[Galaxy S II General] Phistachio:
Hello everyone! :D

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.

IF YOU ONLY HAVE A BOOTLOOP​

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

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!​

__________________________________________________

Okay, so apparently people that come from ICS and try to recover it with the GB files make their phones nearly unrecoverable. So, now I've divided the guide in 2 sections : the GINGERBREAD VERSION and the ICS VERSION.

Due to popular demand, I have also added an I9100G Version, which is here!

I have also added the I9100

M/P/T

versions. Now I support ALL I9100 variants.

But for the moment, I do not have the G/M/P/T .PIT, kernels or Bootloader, so if you have any of those version, only flash what is in the provided package.​

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 :

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

ONLY FLASH WITH RE-PARTITION TICKED AND A PIT FILE IF YOU ARE SURE

THAT THE FLASH WILL SUCCEED.

Which means that you CANNOT have a damaged USB, corrupted drivers and such.

​

When recovering from a soft brick, it is recommended, not mandatory, to have Re-partition ticked with a .PIT file. So you must be extra careful when you are using a .PIT and Re-Partition. And obviously, the red box is the one where you can't and don't want to mess with ;)

But where are the files going, you say?

.PIT -> PIT

APBOOT -> BOOTLOADER (or PDA if flashed alone)

CODE -> PDA

MODEM -> PHONE

CSC -> CSC

***If you have a 1 file .tar package, then flash it in PDA***​

There is only 1 way to recover a soft bricked phone. How to recover from a NAND corruption? We'll get on that later on ;)

__________________________________________________

Recovering a soft bricked phone​

1) Grab the Recovery Package, and you'll see a bunch of .tar files. Take a look at the names. You'll see CODE, MODEM, CSC and .PIT. Put each one in its place.

2) Turn off your phone. Enter Download mode by presing Volume Down + 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)

Now here, take a breath​

First try flashing

WITHOUT

the .PIT and re-partition. And only if it

DOESN'T WORK OR FIX

then you flash with the .PIT and Re-Partition ticked.

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

Now, if your problem is the NAND rw coruption, and wasn't fixed by the above fix, then follow these steps :

5) Download the Kernel. Flash it in PDA. Without ticking Re-Partitioning

6) Successful? Nice, hope is still present.

7) Flash the recovery package, following steps 1-4 This should fix your issue. If it does not, then :

WARNING : FLASHING A BOOTLOADER IS DANGEROUS. FLASH WITH EXTREME CAUTION.

8) Download the Bootloader. Flash it as PDA or Bootloader in ODIN. Without ticking Re-Partitioning

9) Flash the Kernel, as in step 5

10) Flash the recovery package, like in steps 1-4 And that will fix any of your issues :D

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