How to update Galaxy S2 GT I9100 with Official XWKL1 Gingerbread 2.3.6 Firmware
Good news for Galaxy S2 users as an all new Official firmware has arrived and is dubbed as Gingerbread 2.3.6 firmware. This update will be very short lived as an all new Official version of Android 4.0 ICS will be rolling out very soon in 2012. Though this update is official you can update with the help of KIES too but for all those who are on the beta firmwares and KIES doesn’t recognize the device too can apply this update as we will see in the due course of the article on how to manually apply tis update. The update which we will be checking out is specially for Indian Galaxy S2 GT I9100 users, though it can be applied by any S2 I9100 users as it’s a Global update with Multi CSC. The version is dubbed as XWKL1 Gingerbread 2.3.6.
Note: This update is not for Galaxy S2 I9100G users and is strictly for the devices of whose the model number is GT I9100. If you are not sure of the Model number then you can find by dialing “*#1234#” in your phone after which you will get to see the model number of yours.
Disclaimer: Please note that this process of firmware update is not recommended for the basic users and is only recommended for the advanced users. Also, we should not be held responsible for any damage happened to your device in any manner after applying this update.
So, let’s proceed with the list of pre Requisites you need to follow after which we will see the procedure in the next page.
Pre Requisistes:
- So as to ensure that the data is kept safe, you need to backup the same using the below mentioned tips so that just in case if the data gets erased or gets corrupted, the same can be easily restored with the help of below mentioned tips.
Note: Don’t backup the below mentioned data with the help of KIES as it may or may not support KIES after the update.
SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
Notes – Manually save the notes in your mail as these will be lost in the process of firmware update
Call Log - Call Log and Restore
Images, Songs, Videos, Files – Copy to internal / External SD Card,
APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names”
- A minimum of 50% battery charge needs to be there left in the device so as to ensure that the phone doesn’t get turned Off in the middle of firmware update. The APN Settings are located in this path, Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names, you need to note all these manually on a piece of paper so that you can reconfigure the same. Disable tools like Security Suites, Firewall tools and also the KIES PC Suite as these tools generally tend to interrupt the process of firmware update.
So, once you are done with all the above instructions, it’s time to proceed to the next page where we will see on what are the instructions to update Galaxy S2 with Gingerbread 2.3.6 XWKL1.
Pages: Part 1 Part 2

is this the latest official FW???
yes its the latest version.
Hello Pradeep,
I tried upgrading through KIES to FW KL1 but it remains stuck on the page which shows…”Preparing Upgrade Components”. Any ideas on how to update.
Will updating through odin manually to KL1 void my warranty?
no it wont void the warranty, infact its an official update!
Dear Neela,
Does this update (XWKL1 Gingerbread 2.3.6) support arabic
it doesnt support arabic update!
Thank you pradeep for this very nice article.I tried to update my sgs2 with kies 4days ago.It stopped in the middle and the phone didn’t reboot.I searched for a solution and luckily found your aricle.I got my phone using a USB JIG.I followed your instructions and got my phone back alive!!!and all the data is SAFE.
ONCE AGAIN THANK YOU VERY MUCH
with regards

Hi
I had updated with “XWKK5 Gingerbread 2.3.6″ few days ago so.. is this needed.
Where will the other file goes? Kernel_ I9100….? where will you click it… there are two files on the zip folder… will we use only the first one? thanks.. and after this can kies recognize the phone??? Thanks mate..
I will be waiting for you reply and by the way.. great work… appreciate it much
ITS MENTIONED IN THE ARTICLE, PLEASE REFER THE SAME!
Dear Niel,
Thanks for providing the latest official update, I am using the Beta update provided on your website, I am downloading the firmware now but when I go through the installation process I guess you missed the file name to be selected and it only shown as empty commas, so kindly provide the file names to update both the files in a proper order.
Cheers,
Pinaki
How to root this firmware i upgraded via Kies to 2.3.6
update it manually
In your instructions, you ask us to click on PDA and select the file “”. Please specify which file, as there are two. Also do we have to do it two times, as said in the instructions ???
KINDLY READ THE ARTICLE, IT HAS BEEN FIXED!
I manually installed this version but is not recognized by Kies. Why?
install the kernel too! and update the kies!
Hi Pradeep,
I think you need to edit the article a bit as the places where is says that we need to select a PDA file doesn’t says which file we need to select and instead only ” ” are placed over there.
So without knowing which file to select at a particular point, I suppose none would be able to install this update.
hi prashant, sorry for the same. we have made the changes!
Does 2.3.6 has improved battery performance compared to stock 2.3.3?
Hi Neal
i updated the PDA file and then i did not updated the kernel
instaed i used the CWM 5 kernel provided by you for rooting
phone is working fine
I dont understand y u asked to flash the kernel file “Kernel_I9100XWKL1.tar.md5″ ??
i guess its already in the main PDA file
NO, ITS NOT THERE!
but i used the method i told u above
and phone is working fine
Same question. y do v need to install that kernel file. Coz my phone is working perfectly with installing this kernel file. please explain pradeep.
if you install the kernel file and update the KIES to the latest version. your device will be detected by KIES as official version!
Sorry in delaying to your comment as due to heavy comment load, sometimes delay occurs in replying!
Anyone know what’s changed between 2.3.5 and this, other than the standard Google enhancements?
Hi Neal,
My first question on the Android Advisces was if there will any update to get 3g Video calling available on the Galaxy S2, well its finally answered in this update… YES, We can now make a normal 3G Video calls to any phones which support native video calling. I dont mean Skype or GTalk, just the regular Video Call. AWESOME. I really hope that this function will not be removed from the Ice Cream Sandwich Update. Thanks Neal for Bringing this Update to us. I know that many users have been desperate for this function.
Cheers Mate.

the paid apps will be stored in your account!
Hi Folks,
I just updated both the files and its successful, just one doubt, my Kies was working with the Beta firmware as well as this official one of 2.3.6 but it was showing “this device cannot be updated by Kies” on Beta as well as on official one. any Idea why…?
After update my Kies shows ” Firmware cannot be updated through Kies” on the home screen
Any Idea what’s going on…?

Is it possible to update Europe phones or only for indian versions??? plz reply me
yes assmeer you can update!
Just to update, the battery usage has improved significantly and also the charge time. The Media Volume is quite loud now on the stock player and Audio has improved, Now I feel the Rumbling Bass as it should. Mentioning again about the Native 3G Video Call works.
I dont care about the IPhone Siri, I like to use my phone and its fun organizing and searching things on my own. and with this update, the Iphone 4S is beaten down again.
I have done all my updates from this site and honestly it Rocks. Thanks Neal and the Android Advices Team for bringing the best to the Android Community.
Thank You All and have a Wonderful New Year, ICS Hurry home to papa.

have you updated the kernel?
s i updated the kernel too
remember to uncheck the the debug mode to conect to kies.
hey neal, im using win xp to update my firmware, odin works fine with the ID section ‘yellow’. but its taking like more than 20-25 mins to update and gets stuck at ” Enter CS for MD5..” and i unplugged my phone. Is this normal??? It didn’t take this long frm win7!!

Added!!
Odin v.3 engine (ID:14)..
File analysis..
Enter CS for MD5..
Leave CS..
Can’t open the serial(COM) port.
All threads completed. (succeed 0 / failed 1)
check with the usb drivers and install the latest kies!
i already did that. I have kies 2.1, btw i got both the firmware and the kernel re-installed but kies still doesn’t recognize my phone!!!! plz help me out. The whole reason i updated from 2.3.5 to the official 2.3.6 was to get kies to recognize my phone
you need to update the kernel and also you need to update the KIeS!
After updating to this FW apps are not supported. eg.citibank, call track . was working with xwkk5. But issue with that fw was phone use to restart after few hours if connected to wifi. This fw is stable but i am not sure why apps are not supported.
I have done as you said but still its not recognized by kies. In download mode it shows SUMSUNG OFFICIAL but when I connect it for KIES it says ” your device cannot be update by Kies. Why its happen. I flash the kernal also as you said.
Please give me a way out.
you need to update using the Manual method, since you are on non official firmware, you might not get this update via the KIES!
kies not recognized it… any other method..
install the kernel and check, also update kies!
update the kies & it recognized. thanx for original ROM. keep posting…..
I had Done as the procedure given above………
I have Downloaded the Kernel..
How to Update it .???????
you need to update from the Odin!
For the Android Lovers, who are having problems getting their phone recognized by Kies, Please follow the instructions provided By Neal every step by step and you should not have any problem with Kies from there on. I have already mentioned in the earlier posts about the improvements in this Update. Kindly read the instructions carefully and follow the same to update or else your result will be that its not recognized by Kies, you might brick your phone or worst case scenario…..you might end up with a very expensive paper weight. Instructions are very clear and precise by Neal.
Thank You Neal and Android Team, You Guys Rock.
thanks atik!
I did it through moblie odin,the whole process took 3 min.update went smooth,the device remained rooted and irritating “yellow triangle” also disappeared.
thanks
Dear neal,

to unroot, you need to again apply the firmware with which you need to update!
So this is the Indian version of the firmware? Because I wanted to root after this update and use the stock kernel for XWKL1 because I couldn’t find the kernel for XWKK5.
you need to apply for the kernel XWKL1 only!

Do you have any advice on this problem?

Hello Pradeep:
Thank you very much for this firmware update, Its Rocking I upgraded from 2.3.3 to 2.3.6 and lots of bugs have been fixed in my S2.
Including my battery issue which use to drain out in 8~9 hours, after the upgrade I am able to fetch my battery to 10~12 hours. Which is remarkably good.
However I found a issue after the upgrade, whenever I open any application, there is a slowness and able to see the pixel by pixel on the screen while opening the application.
Earlier this was very smooth and fast without any delay in opening the application.
Pls help if this is a know issue.
Regards,
Vivek

how do you update kernel on odin?
we have mentioned the same in the article!
correct me if im wrong if i understand it correctly when u say update kernel it is the step where u flash the kernel on odin? (this step)
■ Once phone is connected, the ID : COM section will turn yellow. Click on “PDA” to select the file “Kernel_I9100XWKL1.tar.md5” and then click on “Start”. Within a minute the device will be restarted. Now after you see the home screen, remove the USB cable to enjoy your Galaxy S2 GTI9100 on the latest and official Gingerbread 2.3.6 update.
because im done with that but still kies cant do update on my phone…
yes, in odin you need to flash! its mentioned in the article on how to flash!
Also, after that update the KIES

Hi Neel,
Successfully upgraded the phone. The phone is Indian make and is to be used in India. Followed the exact procedure as mentioned but still kies is not recognizing the phone. At the end of my current firmware listing it shows XEU in brackets. I think that is the issue…. Can you please guide me to change that and get my phone re-detected…Do I need to do anything else like factory reset or cache clearing..?
Waiting for a quick and positive answer..
Thanks
Dhrupad

Rgds..
Andrew

I hope you provide me a solution.
warranty won’t be lost!
Is it possible that you can provide with a CSC file for this firmware so we don’t get an error on kies???
no, its not possible!
Hi I updated my SGS2 to 2.3.6. The process was smooth and flawless. But after the update i am facing issues with WIFI connectivity. Once connected it works fine, but as soon as it goes in idle mode or the screen is locked if i stop using my phone, with WiFi switched ON the trouble begins. When I unlock the screen and again try to browse using WiFi the net doesn’t work. I need to restart the WiFi again so as to browse again. This issue happens again and again.
There was no problem prior to the update. Any solution to this problem?
its fixed in XWKL2 version!

thankyou for the reply in advance
hiThank you Pradeep Neala very much.
I followed your 2.3.6 Upgrade instructions to the dot and the upgrade went without a hitch.
My GS2 is much nippier now and I find it connects to my Belkin and D-Link WiFi router much better, with increased range. I am also able to get full 4Mbps on my BSNL broadband connection, although I am not sure it is related to the OS upgrade. Earlier I could not get more than 1.5-3Mbps try as much as I did at various times of the day.
Do you have a comprehensive list of enhancements which 2.3.6 does over 2.3.4? Please reference if u do.
We nor eagerly await your upgrade on ICS for GS2 (Presently, 4.0.3 seems buggy, from the comments on your blog).
I will still follow your instructions, as Kies is much too unreliable. I wonder why Samsung messed up so badly on Kies.
Do you have any heads-up on the release date when official ICS will be released for GS2.?
Thanks once again
yes, very soon the new builds will be getting released!

Hello there,
I updated to this firmware and got the force close errors. I can’t do a wipe cache/factory reset because it’s asking me for a password, even if I try to flash it again it fails. Can you help? I’m without a phone now
kindly flash the same again! there is no password asked in your phone!
A late bloomer I must say… Thank you for steps. It worked out perfectly and I am now on 2.3.6. Just to share my experience, my first upgrade from 2.3.4 to 2.3.6 did not work as expected, the firmware got corrupted and a visit to the service center helped me come back on track, the guys there put me on to a 2.3.3 and gave me some gyaan on the do’s and dont’s of upgrading. I went ahead now with the steps as mentioned here and lo.. behold… 2.3.6 is installed…. Thanks once again.

3) What is the use of installing new kernel?
Thanx in Advance
ues but an all new version has arrived for which you need to refer the s2 section!
I am having a similar issue. I have updated both files through Odin (the first one and the kernel). The phone seems to be working ok, but when I connect to Kies it says \Your device does not support software upgrading via Kies.\. I have also updated to the latest version of kies on my pc.
Should I not be able to update via kies after I have followed your steps?
Thanks in advance.
no, you need to update the device manually via ODIN
Thank you !

Dear Pradeep,
The firmware is working awsome…Thank you guys…
My phone is getting connected to KIES seamlessly and it is showing that it is official…
And for all those people who faced battery drop issus initially…Even i suffered 50% drop in battery charge over the night time…
Following is the solution which worked for me and now my battery survives for complete 2 days with moderate usage…
Complete one battery recharge cycle.
Enable When Screen turn off option in Wifi Sleep Policy
Wifi and Network – Wifi setting – Advanced Option – Wifi Sleep Poliyc – select When screen turn off
Deselect Turn off Wifi option in Custom Power Saving Setting.
Hope this help you all…
also switch off Market Data, Data Sync, GPS, Wifi, Location when not required…It gives tremendous boost to the battery.
Enjoyyyyyyyyyyyyyyyyyy
Does it take so long when select file “GT-I9100_INU_I9100XWKL1_I9100ODDKL1_I9100DDKL1.tar.md5” and click on “Start”?
ideally it should not take more than 5 minutes!

hi i am using the samsung sgh i727
i recently updated to the 2.3.6 (gingerbread.ucla3)
this version is very irritating. i cannot connect to any wifi networks and the battery is also draining very fast.. please help..
All,
I’m also facing same kind of issue “Your device does not support software upgrading via Kies”
Let me explain what happened exactly:
1. After 100% charged we get an notification on top stating that 100% Charged , when I unplug the charger after that battery percentage will go down to 95% or 96% immediately as on when unplug the charger
2. And my S2 was little bit hanging while operating
3. While charging mobile is getting heat
Because of all the above reasons I have approached Samsung Servicing Center (authorized) and I was to told that there is problem with Mother Board and needs to be replaced and need to update the OS also,
After 3 days I got my mobile back with replaced new mother board and software updated, after that also above mentioned (Point 1) issue not resolved and moreover I could see and new issue that, when I tried to connect my mobile to KIES it says that “Your device does not support software upgrading via Kies” and it’s showing only current firmware version and not showing that this is the latest firmware version,
Not sure what to do, today again I have approached Samsung Servicing Center to take look into that,
Could someone had same kind of issue, please advice me on this.
Forgot to provide my Current firmware Version: I9100XWKL1/I9100ODDKF3/I9100DDKE4/I9100XWKL1 (INU)
Please help me out in this.
Thanks NP,
Awesome guidelines and indepth “How to” help me get my S2 on new android version 2.3.6. I read this article & the comments atleast 10 times to avoid the confusion/problems & inspite of following all the steps I got one problem which was:
Added!!
Odin v.3 engine (ID:14)..
File analysis..
Enter CS for MD5..
Leave CS..
Can’t open the serial(COM) port.
All threads completed. (succeed 0 / failed 1)
As I mentioned … I read all the comments and then made my PC equipped with latest version of Kies and USB drivers. But still this problem was reoccurring. Then I did the thing which is not mentioned in the article. I cleaned my S2 … cache, history, running apps. & then atlast …. yuppie …. it worked. Now my S2 shows its Android 2.3.6 and also get detected on Kies.
Thanks NP once again for all kind of untiring support.
Balkrishna.
hey bro my phone is stuck on s2 animation and its keep restarting but not showing home screen
what to do ??
first your ICS ruined me, and now the password for this package is bogus. Wow advices.com, dont want anything more from you. Pathetic level of diligence.
hello,
After the update using odin, I connected my phone to kies and what i recieved was that the phone is not supported for kies update. Is this a problem and also does it mean that i can use kies to update my phone again.
thanks
Hi Np,
I had been following your procedure and after first step. I am not getting yellow box as mentioned below…. What to do??
“Once phone is connected, the ID : COM section will turn yellow. Click on “PDA” to select the file “Kernel_I9100XWKL1.tar.md5” and then click on “Start”. Within a minute the device will be restarted. Now after you see the home screen, remove the USB cable to enjoy your Galaxy S2 GTI9100 on the latest and official Gingerbread 2.3.6 update.”
I restarted the phone and allowed omputer to get all drivers, as i was getting USB drivers issue… now its working fine, thanks buddy!!!
Now tell us the procedure to update for ICS…:))
I did what you said but it won’t start,continues to restart and seeing and seeing again the same samsung logo . please help
Hi,
I updated the firmware, but when the phone restarts, it keeps on showing the starting screen with “S” logo and doesn’t proceed further. kindly help..
Hello, I have followed your instructions to the letter with this firmware 2.3.6 but the phone and Odin is stuck at SetupConnection.. for the last half hour. is this normal?
How can I restart the process, because I cannot remove the USB cable. I want to wipe the phone completely and restore to 2.3.6. from 4.0.3. I had serious problems with 4.0.3. and the phone will not even boot
Hi,
I’m from India and have been watching all of your articles about GS2 and i updated my GS2 to 4.0.3 as and when it was released and later i reverted back to 2.3.6 xwlk1 through Odin following your guidance lines. My phone is working fine, but sometimes when the phone is in idle mode (i.e. screen off) suddenly it turns on and turns off. There won’t be any sms or miss call when i check. Is this a virus problem or any malfunctioning? I’ve got Antivirus installed in my phone too and that didn’t find any virus either.
One more question, when i connected to Kies it is detecting/recognizing but when i hit Firmware upgrade and initialization showing “GT I9100 does not support initializing.” Is this a problem when Samsung releases official ICS to update my phone through Kies?
Please suggest.
Pradeep i have android 4.0.3 on my I9100 but i want to downgrade is there any risk….please reply asap
