How To Update Samsung Galaxy S GT I9000 with Xtra Long Battery Amestris ROM v3.5

Amestris ROM LogoIf you are in search for a custom firmware for your phone then you have come to a right place as in the due run of this article we will see on how you can taste your phone with the final and stable version of custom ROM called as Amestris ROM which has the version number as 3.5. There are quite a few number of enhancements which this version of custom ROMs comes along which we will see in the due course of this article. While the Froyo was themed and was wet in the blue colour, Gingerbread in the green colour, this Amestris custom ROM is fully filled with the Orange colour which i think is really a nice visually appealing one as shown in the screen shots in page number 2 of this article.

Just in case if you wish to know all the features which this phone comes along then the below listed features might just grow on you to make you move applying this update for your phone. Just like its earlier version of firmware, this version of firmware too is based on the Gingerbread 2.3.4 XXJVR Edition. Also, additionally, note that this ROM Firmware is not in any manner is released by the Samsung Electronics as this is as it’s a custom made ROM built by various developers. Also, this update of Amestris ROM can only be applied by the users who have rooted their Galaxy S GT I9000 powered with the XXJVR 2.3.4 version.

It has been found that several times many users tend to apply the updated for the wrong phone. So, before proceeding to apply this update, ensure that you only apply this update for Samsung Galaxy S GT I9000 and not to any other similar phones like Samsung Galaxy S GT I9000M or I9000T or Captivate or even to Mesmerize etc. We take no responsibility in what so ever manner in whole or in parts if you still proceed with the updation of device. So, ensure that you don’t proceed with the instructions if your phone is not Galaxy S GT I9000.

Please note that If you are not sure of whether the version you are On is XXKG6 or not then you need to head to the path from your phone which is Settings > About Phone > Firmware Version where you will find the version of Android OS where it will show XXJVR 2.3.4

How to Check whether the Phone is Rooted or not?
The simplest and the easiest method to find this out is to find for an application called the Super User application in your application list which will be in the skull shaped icon. If you are able to see this application in the application list then that means that the device is rooted and you are ready to proceed with the procedure of applying this update.

Disclaimer: We take no responsibility in any manner if any damage occurs with your phone which is a very unlikely event if you follow each and every single instruction which is mentioned in the due course of this article. Although if at all there are any issues then do report us in the comments section and we will help you in solving the same.

Note: In the process of updation you will be losing all the data which is SMS, Contacts, Music, Videos and Pictures if they are stored in the phone. All the contents stored in your external SD Card will stay intact and no contents will be modified in the external SD card. Additionally, all the APN Settings as well as the MMS Settings too will be erased, so you need to ensure that you are noting all this settings somewhere so that you can then restore the same by configuring it manually once the firmware updation process is done.

    Best custom rom I have tried in terms of battery life, however, I have noticed that several apps keep automatically popping up in the active apps (running even without user intervention) – I noticed this on the go widget which monitors apps opened… this was very odd hence I changed to another rom. Currently on Darky now – more stable but batt life is not as good as amestris.

    Lastly, when you’ll post the latest Amestris rom (v3.6 or v3.6.1)?

    Thank you

    • NeaL Pradeep

      September 14, 2011 at 11:51 pm

    Updated to Extra ordinary rom 3.4 on Galaxy i9000t. I know the instructions said it was not applicable to this device but I felt left out. Anyways for the most part it work good except that I was not able to make a data connection and some menu keys were not visible.

    I am now considering block buster 5.0 or amestris 3.5, battery life and ability to connect to kies is a must which do you recommend?

    • NeaL Pradeep

      September 17, 2011 at 11:58 am

      September 17, 2011 at 12:05 pm

      you need to again download the apps from the market!

    For users experiences battery drain in their Android phone. This could be because of goggle map with new version (4 and above). You can check (main > Settings>about Phone>Battery use). IF maps is showing high usage please remove updates and install again while charging phone. You may have to do multiple times till you dont see main in high usage (Dont ask me why).

    This gave me almost double of battery life. Good luck.

    September 7, 2011 at 7:36 pm

    • NeaL Pradeep

  35. Umer

    September 5, 2011 at 5:38 pm

      It is easily installed if the procedure is followed.
      Like any other ROM it has it’s pro’s and cons.
      I like the battery life, a couple of the apps. inculded. Phone clocked at 1376 (quadrant) which is more than double Std.
      Apps open and close quicker.
      Three things I miss (and preferred in ExtraOrdinary ROM) are the blue increment line when phone powered on, the full screen stand-by mode picture and the notification bar at the top of the screen was green – now orange (I don’t like orange).

    Can i use KIES application to restore the contacts, videos and photos backed up previously after the Amestris ROM v3.5 update ?

    Does kies recognise the device after updating it with custom rom ?

    i am using XXJVR stock rom and i could not find the ‘import contacts’ or ‘backup contacts’ in the contacts menu inside ‘more’ as explained in

    • NeaL Pradeep

      September 5, 2011 at 3:31 pm

      no, kies won’t be recognizing the phone after updating with this version of firmware!

  42. Kath

    September 4, 2011 at 4:05 pm

    Al these options are very tempting to me.
    But I’m not familiar with this Amestris roms so I have a couple of questions:
    Does it support the Dutch language?
    Does it also still has the SWYPE text input method?
    Can I keep using the Go Launcher EX?

    • NeaL Pradeep

      September 5, 2011 at 3:29 pm

      yes it has swype and yes rest all you can customize the phone!

    Everything works smooth and fine!

    P.S.: “Quadrant Standard” points on my “SGS-I9000” for

    “BlockBuster 5.0 Custom ROM Firmware” = 1350

    “Xtra Long Battery Amestris ROM v3.5” = 2150


    • Maniz

      September 5, 2011 at 8:15 pm

      I don’t really care Quadrant Standard score, it doesn’t reflect the performance of your devices, if lag fix is on score will be high. What I care is battery life, GPS, wifi and mobile networks, and bugs. I am happy with 1400 QS score if these things are better. Currently using stock XXJVR with semaphore kernel 1.6, will you believe it battery life of my SGS is 36 hours after more then normal (almost heavy) use?? But QS score is only 1450 🙂

      • adlibitum

        September 7, 2011 at 6:24 pm

        Hi, Maniz !

        I agree with your comment! Indeed, you are right! But, as you see my main aswer [about] “Xtra Long Battery Amestris ROM v3.5″ is that „Everything works smooth and fine! And I wrote „Post Scriptum“ some additional info, knowing that „Quadrant Standard score“, doesn’t reflect the performance of the device.
        Before all, I would like to write that I‘m fan of all which is better than before in broad sence. For this reason I like to experiment and to try different tnings. For instance, as for now, I had tried all proposed firmwares and ROMs as well for SGS-I9000. My last favourite was “Extra Ordinary ROM v 3.3”. But the drain of the battery and some occasional force close errors continued my search for something better.


        So, straight to the point – the performance according to my (e.g. my observation) of SGS-I9000 on “Xtra Long Battery Amestris ROM v3.5″:
        # When is full charged the display show me [for instace today], that battery life has 62 hours.
        # GPS : from 10 to max 15 seconds for primary location (for „Google Maps“ and „Sygic 3.0 Aura“ as well). And after that the GPS-navigaton work without no interruptions.
        # The Wi-Fi connection is also perfect and stable.
        # As for now, I have not seen any force close errors or bugs and so on.


        I know that this sounds too good to be true. It doesn’t matter, because I don’t want to convince anyone of anything. Moreover, I’m looking forward to the next new firmware or ROM to try it.


        • adlibitum

          September 7, 2011 at 6:28 pm

          P.S.: It is clear but anyway – “aswer” to be read “answer”.

      What phone and model do you have..
      Updating your phone ROM you need correct download files according to your phone model and country you based in..
      This website has links on how to root your phone..
      Also custom ROM is updated not purchased via Odin or other methods..
      What kind of hardware?? I think you meant to say firmware
      Any questions reply back

    Hi Neal, thanks thanks 🙂

    Currently on EXTRA ORDINARY ROM 3.4, after following the procedure of wiping of cache e.t.c. Can I flash the zip file in RECOVERY MODE, as already base version is XXJVR. OR do I 1st need to do the whole thing again i.e go back to stock ROM, root it and than install the zip file. ?????
