[Galaxy S II Q&A, Help & Troubleshooting] Geronimo2013:
Hello there

I am back from Seoul... where I bought a SHW M250S. With a official rom, I have updated it to 4.04 but, it's still Korean/English...

So for this reason, I would like to upgrade to i9100, and to JB 4.1.2 also.

Yes, my questions seems to have been seen a lot of time, with some answers, but, I spent hours checking internet, and all of them just over fly the subject. If you are the one who have succeded in this task, help me....

If you know where I can find a REAL tuto, with precise and clear answer, not so:so informations....

If you want to create a nice Tuto ....

The most advanced tuto is this one, but still so many questions....

Thanks to not send me back to this post :

Thanks in advance

Geronimo ;)

1. Siyah Kernel 2.6.13 korean version (you can get it from siyah's site; thanks!) > Korean version ???? :confused: Only 2.6.13 ? witch is old.... May I use 5.01 or 6.0b4 ?

2. Odin (latest version) > for PC ??? 1.85 ???? 1.87 ?

3. Mobile Odin (search this forum... credits to Chainfire... this is the most important soft on this tut) > But Mobile Odin is not free... :crying: What version ? 3.01 3.57 3.67 ?

4. M250S rom. Search for the torrent of [Root]HOME_M250S.EI21.1035_CL566114_REV02_user_low_ship ? Only this version ? :confused:

5. An I9100 DX rom. Search for GT-I9100_THL_I9100DXKL3_I9100OLCKL2_I9100DXKL1.tar (2.3.6) Only this version ? :confused:

----LET'S Start!!!----

NOTE1: Make a copy of the i9100 rom / m250 rom / siyah kernel on a microSD... we'll going to use this later...

NOTE2: the i9100 rom should be on the "firmware" folder of the microSD card...

NOTE3: insert the microSD card on the phone...

1. Do a full factory reset of your phone (settings). Setting of what ? Reboot after ? :confused:

2. Put the phone on download mode and flash it with the m250rom above. PDA section ? No reboot after ? :confused:

3. After flashing with the m250 rom, flash the siyah kernel. PDA section ? No reboot ?

4. After the phone restarts (Why it will reboot there, and not at line 2 or 3 ?) :eek:

and a proper setup has been done, open CWM. ClockworkMod recovery.apk ? witch version ? Why only zip ou tar files ? No apk ? I am not supposed to use it on Galaxy S2 ? :confused:

and select "Flash Stock Firmware". Don't worry CWM will not flash the IBL/PBL and SBL.

This will restart the phone doing the flah on the recovery screen...

5. After the restart, the phone should now be running the i9100 rom but remember, kernel and modem is stock from the i9100 so signal might not be that great. (ALSO NOT ROOTED)

6. Put the phone in download and flash the siyah kernel. Still PDA section ? with Odin From PC ? :confused:

7. Restart the phone and you should now have the root goodies from siyah. (WAIT: WHY AM I SEEING THE YELLOW TRIANGLE ON BOOT??? --- NO WORRIES MATE --- FOLLOW THE NEXT INSTRUCTIONS) INSTALL MOBILE ODIN. Witch version ?

8. Select open file on Mobile Odin. Select External SD and look for the i9100 Rom. Enable --- EverRoot / Inject Superuser / Inject Mobile Odin / Inject CWM Manager. Then click, "Flash Firmware". What means Inject ? :confused:

9. The yellow triangle should be removed by now after restart but signal is quite poor since we are using the i9100 modem.

Open Mobile Odin again, select open file and look for the i9100 rom. Select kernel and look for the siyah kernel. Select modem and look for the m250 rom.

10. Enable everRoot, superuser, mobile odin, cwm. ??????? What that means ? :confused:

11. FINALY... CLICK "FLASH FIRMWARE". From Mobile Odin ?
