[GUIDE] How to Prepare Your Phone to Return to the Store or for Warranty Replacement

[creepyncrawly]

I wouldn't hold my breath for ICS via OTA on our phone soon!

Most here would prefer to get ICS through custom firmware rather than OTA anyway.

But if it does come via OTA, the process should be the same.

As far as what to do, of course your reasoning may be different than mine. My son has an sgsII which he is not into modding. So I installed Entropy512's daily driver kernel on it to get improved battery life and some other benefits. His phone is stock UCKH7 with a custom kernel, so it will not receive the OTA update and will stay on UCHK7, which is my preference for a stock phone. My own phone is running UnNamed with Entropy512's daily driver kernel.

Entropy's return to stock method is very simple and is what I'd recommend. Although I wouldn't do it until ICS comes out because you really don't want 2.3.6 stock unless you have to (for the reasons CreepynCrawly describes).

Samsung GSII
ICScrewD 2.0.1 (init.doh 0.2.5)

I thought ICS was coming soon to S2. I get it that the periodic updates aren't worth it.

And can you send me a link to Entropy's method?

Many thanks.

I believe that the international sgsII, the I9100, will be receiving ICS before long. Even so, if history is any guide, it will still be quite a while after that before AT&T pushes it out to our phone.

A link to Entropy's method? I'm not sure what you mean, but if you want to install Entropy's daily driver kernel onto the stock rom, I would suggest you follow my guide, how to flash custom binaries without incrementing the flash counter. A link is in my signature. You'll need to root your phone using one of the procedures in step 2, and then install the kernel using one of the procedures in step 3.

Hey guys, so i followed the instructions and ran the odin one click app. It removed the yellow triangle at boot and did everything swell.

Except the flash counter is still reading 1 count. I bought a jig, and tried holding vol + and - with it in but the phone doesnt turn on. It only turns on when i have my usb cable from the pc in.

Insert the jig while the phone is turned off. Do not hold any buttons. The jig will make the phone boot into download mode.

Creepy:
Thanks for all your work. I wonder if you could put up the UCKK6 equivalents to the UCKH7 stock/stock+root. I just rooted my KK6 phone, (no new ROM, just wanted to freeze the ***king voice talk app that pops up every few seconds.

I lost WiFi and can't complete an OTA update. I understand that a factory wipe might restore WiFi, but don't have any way to back up all the apps etc. I've installed, and it sounds easier just to go back to KK6, and live with the battery life.

Am i on the right track here? Could you put up the KK6 files needed, or point me to them?

Again, thanks for all your work and patience.

Entropy512 has a UCKK6 plus root package in the Unbrick/Return to Stock thread which is a sticky in the development section. You can flash it with Odin3 v1.8x. However, I'm not sure what side effects you might experience going from UCKK6 to UCKH7 plus root to UCKK6 plus root. I'm also not sure if that will restore your wifi, but I'd have to guess it might. Of course, you'll never know unless you try.

As far as making a one click of the UCKK6 package, I might do that if they start shipping phones with UCKK6, but so far I haven't seen anyone report buying a new phone with UCKK6 loaded.

This worked great getting back to stock (Flash the UCKH7-CL503881 stock kernel and system package using Odin3 One-Click Downloader ), i was having some issues that seems to have cleared them up. So right now i'm being a total noob, and yes i did search but the kids are going crazy and cant i concentrate, i cannot seem find how install clockwork mod recovery, i know not to use that app to do it. I know i need a custom kernel, but where and how to install (odin i presume). Again i feel like a tard for asking but im pulling my hair out.

Follow my guide How to Install custom Binaries without incrementing the Flash Counter. It's linked in my signature. Step 2 is rooting. Step 3 is installing a CWM enabled kernel of your choice.

o okay thks. so there is only one offical frimware out for this att phone and it is 2.3.4?

Correct. It's only been less than two months since release.

Is there a 2.3.6 version out yet? I rooted it using Odin3 One-Click Downloader Stock I-777 UCKH7 and noticed that the Android version went to 2.3.4 from 2.3.6 and now my WiFi is not working, not sure if it is related but that is the only thing I can do. I have now removed root using odin, but still have 2.3.4 on it. Let me know if there is a version with 2.3.6 or if you have an idea why the WiFi has suddenly stopped working.

Cheers

Wifi always breaks when you flash back to 2.3.4 from 2.3.6 without a wipe, but a wipe data/factory reset will fix it.

Entropy512 has a UCKK6 stock plus rooted system package available in the Return/Unbrick to stock (or root) thread which is stickied in development.

Why did you post in this thread? This thread is about returning the phone to stock so that you can return it to the store or for warranty replacement.

Thanks used 2a of the guide to set thing correct . Helped to unbrick my phone after flashing

 

[houstonsveryown]

im sorry but i cant get my phone to get past the boot.
i did all that it said and i can get in to download mode still.

UCKH7-CL503881 stock kernel and system package using Odin
still didnt work. i wonder what im doing wrong.

i figured it out. went into 3e recovery and wiped. worked like a charm. i was so scared lol X_X

 

[CyberGhos]

Easy way: make it completely dead and won't even turn on.

 

[Biporch]

Nice guide.

Any idea what to do if Odin won't recognize your phone?

 

[creepyncrawly]

Any idea what to do if Odin won't recognize your phone?

I assume you have a windows computer. If not, you must use Heimdall instead of Odin.

This would usually be either a driver problem, or a usb connection problem.

First make sure that you have the correct USB drivers for the I777 installed on your computer. You should see "Samsung USB driver for mobile phones" in the "uninstall a program" utility of Windows. It is also possible that you have corrupt drivers installed. In that case, you would need to uninstall the drivers, reboot, and reinstall the driver package.

You should use a usb port that is connected to the mother board of your computer. If a desktop, that usually means use the port on the back of the computer. You must also have a good usb cable, as some don't work. Things you can try: use a different USB port, use a different USB cable, use a different computer.
