You have a very messed up phone I see...next time, always remember to flash stuff for I9100G only...stay away from those meant for I9100...

Here's a possible fix:
1. Reboot into recovery and do a factory reset...
2. Flash a firmware meant for I9100G via ODIN with pit file, uncheck repartition (this is very important, double check that your phone is I9100G and the firmware is for I9100G)...it is better to use the ODIN files provided in this thread...
3. Reboot and it should be done...

Are you sure you entered download mode by pressing volume up+home+power?That's for entering recovery mode...It should be volume DOWN+home+power for download mode...

Place the pit file into the pit section in ODIN...check only the 2 options as shown in the first post of this thread...then start flashing...next, enter recovery mode and factory reset...hope you get what I mean...

VERY IMPORTANT ANNOUNCEMENT​


I would like to first apologize for my absence. My past months have been super busy, and they don't seem to be ending anytime soon. And "anytime soon" meaning in a couple of years. And I'm actually glad that this is happening, since I've been working pretty hard to achieve the state I'm in.

This thread has evolved into something I've never imagined. Only because of YOU guys, we managed to turn a normal thread into a pretty popular and well used Guide, and it made me so happy and joyous of being apart of the XDA community. I feel proud in being a XDA nut. This whole success is just because of YOU guys. :)

As painful as it is to say this... I believe that I will be dropping support on this thread after the New Year, because a) I lost my Galaxy S2 in Paris in a taxi with no hope of getting it back when I went there 3 weeks ago and b) I'm probably getting a Galaxy Note 2 in the New Year, so this thread will be most likely ported and maintained over at the Note 2 forums.

I'm extremely sorry it has come this way, and I hope you guys will understand. In the following days I'll be updating the files to their latest versions, and will try to find new bootloaders and kernels, but without sources, I'm unable to do so. I'll update whatever I'll be able to :)

Regards and thanks to all of you that have supported me,

Rafael K.​

Hi, I had softbricked my s2g this morning when trying to restore my previous Custom ROM.My phone went into bootloop mode and cannot go into CWM mode. However, lucky for me still can go into DownLoad mode.
I went thru this thread and found the solution in page 13 by xxnsra
1. ReFlash CWM Recovery thru ODIN.and ..

I am back to CWM mode and managed to restore..........:good:

Hi all.
My problem is as follows and hope that someone can help.
I have downloaded odin mobile and installed it on my S2 I9100 G which previously had CM 10 installed on it and I wanted to flash the official firmware using Odin mobile. I did run it and then the phone prompted me for M5 or Md5 that was detected and should click yes to verify before flashing. I clicked yes then it started verifying and when it was done it rebooted and then was stuck on the (Samsung Galaxy S2 GT-19100G black screen) and did not want to move. I waited for an hour and a half and nothing happened. When I removed the battery (I could not reset or do anything else) and put it back, the phone turned on by itself and stayed still on the starting screen (Samsung Galaxy S2 GT-19100G black screen)

Now I'm not being able to put it in recovery nor download mode.

Can any one help and anyone knows if the jtag dongle can actually force it to go to download mode even at this stage

Thanks in advance for any suggestion

    Hello everybody :D

    Due to some demand and request, I've decided to adapt my guide to the I9100G. It deserves some love too!

    This is a guide dedicated to noobs, so if you're not one, I would advise to stop reading now! (altough feedback would be great! :))

    Yes, there have been quite a few threads about fixing a soft brick. But what I'm writting now is another solution to a different kind of problem : unflashable GSII (which also works with a soft brick of course ;)), which is a soft brick and a corrupted NAND rw (read/write) function.

    Just in case you don't know, a soft brick occurs when you flash a ROM or Kernel, and it doesn't go your way, thus bricking the "soft part", aka Software, of your phone. Therefore, it is easy to recover from. Now, regarding NAND rw (NAND's read and write function being the corruption) it means that it is an issue deeper than a soft brick.

    It is obvious when you can flash a kernel, but you can't flash a ROM, because it can't properly read the NAND, but can flash a kernel. But you ask, why the kernel? Because flashing a kernel is a bit deeper than flashing a ROM. When you flash a kernel, you're changing/putting new instructions to the hardware, and when flashing a ROM, the instructions that are drewn are different and more "simple", so when flashing, ODIN will say "FAIL" instead of "PASS", or suddenly stopping the flash out of nowhere.

    BUT UNFORTUNATELY, this guide will not be able to fix a NAND r/w corruption, due to tyhe fact that I do not have either the .PIT, the bootloader or the kernel, I only have a stock ROM, which will only fix a soft brick.

    As soon as I get my laptop back from RMA (this Pentium Dual core I'm using right now isn't trustworthy), I'll extract the zImage and sbl.bin from each ROM, zip it, upload it, and add the rest of the guide.


    UPDATE 02/05/2012

    GOOD NEWS EVERYONE!    Thanks to maui75, I have the .PIT and the gingerbread bootloader! When my laptop arrives from RMA, I'll download and unzip all the packages in this thread, add the .PIT, zip, upload again, and add the rest of the guide! :D​

    IMPORTANT ANNOUNCEMENT #2

    Please welcome neerajganga, your new thread maintainer (along with me)! He has been of great help, so I think he deserves this kind of announcement!    ​
    ________________________________________________

    IF YOU ONLY HAVE A BOOTLOOP​

    Wipe data/factory reset and wipe cache. IF THAT DOESN'T WORK, MOVE ON WITH THE GUIDE :)

    __________________________________________________


    Let's start with the basic files, downloads and requirements​

    1) You have to know the basics of ODIN and flashing (duh :p)

    2) Just to be safe, please uninstall Samsung KIES. It usually interferes when flashing with ODIN. You must have the USB drivers from your phone, so don't uninstall them. Only uninstall the program KIES.
    Just in case you don't have them, here are the Samsung USB drivers

    3) Download ODIN, the tool that we'll use to flash all the things into our beloved Galaxy S II ;)

    4) Download the necessary ROM (they are Gingerbread 2.3.6) : Africa (Iraq), Asia (Malaysia), Europe (Open Austria), Middle East (Saudi Arabia). (password is samfirmware.com)

    5) You must have WinRAR to unRAR the Recovery Package and to unzip ODIN.
    You can also use 7zip, as sugested by jermitano :)

    And that is it! Let's get down to business :)

    __________________________________________________

    If your GSII has the folowing symptoms :

    • Bootloop
    • Stuck on GSII logo, but already removed the battery to try to fix it
    • Enters Download mode and Recovery mode

    It means that you are soft bricked and is easy to solve.

    But if your symptoms are the mentioned above, PLUS the symptoms below

    • Enters Download mode but does NOT enter recovery mode (usually means a NAND rw corruption)
    • Doesn't flash
    • Bad flash in odin (FAIL after flashing, or the flashing suddenly stops)

    Then it means that you have a bigger issue, such as the aforementioned NAND rw corruption.

    It's time to open up ODIN and start reviving your phone!

    __________________________________________________


    First of all, let's just have a quick glance of how ODIN looks like, and where we should put the files :

    ojgokk.png


    As the picture clearly shows, the green rectangle is where you can tick. Those 2 which are ticked must remain that way. And the red one is well... Where you SHOULDN'T touch :p

    But where are the files going, you say?

    .tar -> PDA

    __________________________________________________

    Recovering a soft bricked phone​

    1) Grab the Recovery Package, and put the file in its place.

    2) Turn off your phone. Enter Download mode by presing Vol. Up + Home + Power button.

    3) Plug in your phone. It will show you, in a yellow box in ODIN, ID:COMx (x being the number displayed, sometimes displays 7, sometimes displays 9, or other numbers)

    4) Once ready and done all your prayers, press Start. Wait patiently. It usually takes 5 minutes to flash.

    Have you done everything correctly until now? Then...

    Congratulations on recovering your phone!​

    You deserve some cake afterwards, and some rest :D

    I hope that this guide was helpful, and if it was, hit the thanks button! :)

    Credits mainly go to Intratech and Sammobile, for his amazing gallery of ROMS and files :)

    Simple and easy.

    I even fixed my Galaxy S2 which was stuck in "Phone-Exclamation-Computer" icon mode. Couldnt even get into Recovery or Download mode.

    My phone showed up on Odin so i just flashed it with the stock firmware.

    Thanks for the guide!!

    Hi everyone.

    My problem was:
    - I have a GT-I1900G and installed a ICS ROM for I-I1900 on my phone.
    - Results: The phone got bricked. The only screen he showed was the famous (phone--!--computer). The download mode and recovery mode DID NOT WORK! (but ODIN recognized the phone)

    How i solved it:
    - Install KIES on your computer (with the samsung drivers only did not work for me) - Restart your computer. After that, see if the KIES processes aren't open (use ctrl+alt+del to see it)
    - Download this CWM (clockwordmod) - CWM Recovery for Galaxy S2 - I9100G
    - Open ODIN, and in PDA select the .tar file of the CWM.
    - Connect your phone (turned on) on your computer.
    - After the ODIN recognizes it, press START.

    If it works, congratz! Disconnect your phone from the computer, and now, probably, you can acess the download mode and see the recovery mode (its the CWM. He enters in recovery mode automatically).
    On the CWM menu, use the options: "wipe data/factory" and "wipe cache partition".

    - Remove the battery.
    - Wait 10 sec and put the battery again. Turn on the phone on download mode (vol down + home + turn on).
    - Download one of the STOCK ROMs on this topic. Extract the files.
    - Connect the phone on the computer, and put in PDA the new .tar file, from the stock rom.
    - Press START.
    - Pray, cry or whatever you want.

    OBS: If it didnt work, try to use another laptop. I installed KIES on my laptop, and it didnt work. When i used my girlfriend's laptop, it worked! And i have absolutely sure that it was all okay on my laptop (drivers installed and processes off).

    I agree with you and in special way for soft brick due to the wrong firmware.
    I wish to add the link for all the file ( PIT, PDA, MODEM, CSC, BOOTLOADER, APBOOT) of i9100G CHN KH4, it is a little old but good to repair the chn version.
    ht * tp:/ /115.com/file/dnecfzp4
    To download the file push the green button... in the begin I had some problem to find all the file for the chn version.... hope will be helpfull:p
