Samsung did a great move by letting Samsung Galaxy S2 bootloader unlock. Therefore, lot of developers are developing custom ROM for Samsung Galaxy S2 now compare to HTC Sensation and HTC EVO 3D which have locked bootloader.


  1. So what type of application that require root,so far dnload fr the android stall without problem.may be I’m too far out need to learn more fr u.

  2. Hard habit to break. After playing with custom rom on HD2, i see that you already itcy to do the same to your new SGS2

  3. Hi
    How long it is suppose to take? My SGS2 is about 1 hour with the “downloading screen” and I don’t know what it is doing.


  4. Hellow Jayce,

    Thanks for the article.
    I hav a few question to ask,
    Do you know other vendor who not lock the bootloader beside samsung?
    is it still the same : power button + home + vol up to boot in safe mode for sgs ii ?

  5. hey so i just got this phone like 2 days ago and i don t want to mess with it. i accidently came across this thing and now i cant get out of it. so what can i do?

  6. hi,
    my grandson was playing with my galaxy s2 and locked it as he was playing with the pattern lock, how do i unlock the phone as ive forgot my gmail and password i used when i first had the phone… or how do i do a hard reset to get in to my phone…
    please help!!

  7. Thanks for the explaination!
    But how do one tell that the firmware is Odexed or Deodexed?
    I am currently on XXKG6 2.3.4 for my SGS2, that I got from your site. Is this Odexed or Deodexed?

    Also, can I use odexed for deoxdexed firmware or vice versa?

  8. Hi Jayce,

    Is there anyway I can get the files to upload Bootloader, CSC, PDA and Phone of SGS2. I made a terrible mistake by choosing to download with ODIN’s Bootloader the kernel_i9100xxki3.tar file. The operation failed but after that, I couldn’t do any more downloads with other options. I also have the Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again message.

    Luckily, the phone is still recognized on my PC and ODIN so I am hoping I can correct the issue.



  9. Hi, I would like to ask for your help. I tried to flash the modem to KG5 using odin. But it stated failed at the end of the process. (it is my first time trying) So I took out the batt and tried to restart my phone but it couldn’t be on. It showed a black screen with a pic of [phone]–!–[com] is at the top left corner of the phone. May I know what can be done to solve this problem?? I am still a noob wiith android. Thanks a lot for any help!

  10. Dear Jayce,
    I did everything you said (wrote) and now I’ve got my phone in Odin mode ( it was and still is my last hope, i’ve tried many many many ways-my friend’s blocked my phone with trying “too many patterns” ) but what now? It’s been like this for about 5 min. I’d just like to know if I should wait & for how long? (as much as i love my expensive SGs2, i don’t feel like staring at it all day long)
    You’ve guessed right, I’m certainly not into that stuff but thios is my last hope. It really is.

  11. Hi Jayce, my sGs2 in in odin mode that says downloading do not turn off target, i know from previous reply that i’m supposed to flash a new firmware but i don’t want to do that. How do i get out of that screen?

  12. Hi there i’ve been trying to download the stock rom on my tmobile s2 and everytime i do i get this far

    Check MD5.. Do not unplug the cable..
