  1. no error message… the phone freezes alot

  2. hey guys
    i need some help
    i have a brother recently rooted my phone to -
    android version – 2.3.6..icecream sanwich…omega
    i having problems with this rom..

    can someone tell me how to change this rom to a properly functioning one?

  3. Awesome, awesome, awesome, no problems at all, follow directions people….Just a small question, at the end of your directions you say to enter into download mode to clear the cache. Now I know from flashing my old v845 that when I go into the download mode there is a whole menu and and option to clear cache etc, but after flashing this awesome rom, i go into download mode and it just tunes me to press volume key up if I want to proceed. By the way, none of my original apps are corrupt when entering home screen so I dunno? Does the cache files clear automatically when entering download mode again or do you have to use odin somehow to clear it? Anyways bro, thanks for this awesome and fast rom its truly legendary that I can keep my warranty etc and still change the stupid green gingerbread look as well as boosting speed etc. Any way to update to 2.3.5 using the same method as above? By the way I am in S.A on the MTN network and came from xxki3 to this rom of yours and the network is superfast, as fast as lightning you could say. Thanks again, God Bless ya soul for this. SUPERSTOKED.

    • thanks kyle for your appreciation!

      • No worries bro, you must have worked your ass off to get this rom as perfect as it is. I am currently using the darky ota app on the market to change various things, mostly just the kki4 modem and some visual aspects, working ace bro. If you could tell me, is there any inherent danger with using darky ota app with this rom of yours? I have not noticed anything but read somewhere that blue on the sgs2 screen can cause the burn-inn phenomena. Anyways, thanks a million, is there any way I can donate to say thanks? I know on the xda forums etc I can donate by pressing a few links, does it work the same here? Thanks again Pradeep and, ‘Nameste’.

  4. Hi Neal, boss you rock.

  6. I mean the sound on the camera… i do like my bells ad whistles

  7. Where?

  10. The rom works very good. The only issue i notice is that i don’t have a shutter sound on camera app. Is there a fix?

    Thanks and keep up the good work.

  11. Hi, i have a question. My SG2 has 2.3.4 UMKG4 can i update directly or do i need to update to KH3?


  12. Hey Neal.. Does upgrading to Litening ROM requires rooting?? will i be voiding my warranty if i update to this??

  13. hi neal i recently updated my s2 to 2.3.5 from ya other post …now can i install lightnin rom on that…with out any hurdles……

  14. Hi Neal,

    Notice a few lagging/staggering effects on the Lite’ning ROM when I am receiving calls.

    I was hoping to revert back to stock ROM, but have got glued to the:
    1) % Power Meter
    2) CRT Effect

    Have noticed online (Youtube and other forums) that this can be done separately without having to install custom ROM.
    Can you please advise how to achieve this.

    I would be glad if you can share the files, links and instructions (preferably doing via Odin, instead of Clockwork Recovery Methds).

    Do let me know if you can assist.

  15. Hi Neal …

    I have successfully flashed and moved to Litening ROM.
    The effects are really cool … but I miss the swype keyboard.

    Any idea how I can install the same ?!

    Is there a way to check and kill unwanted apps and processes … now that I have rooted …

    Another quick question, where can I get more information on this “Superuser” app … ?!!

  16. mine has been hanging for way longer than 10-15 min.. its stops here..

    Leave CS..
    Odin v.3 engine (ID:3)..
    File analysis..
    Get PIT for mapping..
    Firmware update start..
    NAND Write Start!!

    any solutions?

  17. Hiya Neal Pradeep,

    Coupla questions:

    1) Can I install the Lite’ning ROM over Gingerbread 2.3.5 (i see that this page recommends 2.3.4).

    2) Once I have installed the latest Gingerbread (either 2.3.4 or 2.3.5) I can flash and install Liten’ning ROM, correct? Does this mean the phone is rooted. So my basic question is do I have to do anything else to root my phone in order to make certain APPS (Juice Defender, etc) work more efficiently ??

  24. Hey Neal Pradeep.. I have upgraded Galaxy s2 to 2.3.4 XXKG5 version referring to your article itself from this very website.

    Is there any way to install the official ROM for SGS2 so that I can get updates from kies if any.
    if it possible where i can find the same.

  35. Hi Neal,

    Just a couple of questions:

    - Should I select the check box for repartitioning if I am uploading the PIT file? I noticed it was unchecked in your screenshot.
    - Also, in recovery mode should I also restore factory settings on my phone after flashing firmware? Some guides suggest doing that and some don’t.

  36. Hi Neal Pradeep,

    How do I know which Lite’ning ROM i must/can use on my Samsung galaxy s2? If any ROM is okay, which is the latest?
    IS the Lite’ning ROM compatible with all the stock software (except for the browser) ??
    Will I face any issuesing trying to flash Android Gingerbread 2.3.3 – XWKF1?

    Can I backup and restore the old stock ROM?

  37. i havnt use USB DEBUGGING mode ON
    any problem

  38. Hi,
    I just applied teh ligtening rom. All has gone well but I would appear to have lost my CWM application ?
    How do I recover this ?

    I used CWM to save my previous rom.

    Thanks for any advice


    • Ok, I resolved the problem.

      Although lightening comes as rooted, you lose the cwm applications.

      To get this back just follow the rooting instructions ( do it again if you did it before installing ligtening rom ) and you will get your cwm back.


    • download the same from the market!

  39. I mean custom firmware counter so that Samsung will be able to know how many times the device was rooted

  40. How can I remove the information added after the rooting I did from the download mode without using a Jig? Your kindly assistance would be most appreciated

  72. Thanks neal ive updated to the new rom update. only problem in my s2 is that while in camera mode, there is not shutter sound when i am taking snaps. Can u help in this regards…

    • go to settings and set the shutter sound!

    • Hi Neal and everyone! I double-checked this problem just to make sure. I reverted to previous firmware and stock ROM XXKH3. Then updated to Litening ROM. After updating, I immediately opened camera and took a shot. Result: No sound of shutter. Will have to revert again to firmware XXKH3 and stock ROM and check camera sound.

    • Hi Neal! I found solution to this problem. Replace the following camera sound files: camera_click.ogg, camera_click_short.ogg, and Shutter_01.ogg and re-boot your phone. The files are found in /system/media/audio/ui

  73. O yes, thanks Neal, updated with the Superfast Litening ROM, works great!!!
