I need help recovering my GS3, i tried using CF auto root to root my phone and i guess it didnt work because my phone doesnt boot past the samsung screen.

I tried flashing stock firmware using kies but it encounters a error saying its a problem with my phone, I tried using odin but it also gives me an error when flashing firmware saying

What version of Android did you have on your phone when it last worked, stock or custom ROM?

Are you still able to get it into download mode?

Press and hold volume down + home + power at the same time

thats koo but the problem is i dont think my phone is rooted, i cant adb push using twrp cause my device wont show up when i adb devices

If you had the 4.3 bootloader on your phone, you cannot use Odin to flash a stock ROM.

Were you running the stock AT&T 4.3 ROM?

Based on your Odin printout in the first post you were flashing a modified 4.1.1 kernel to install root. This should be fine if you were on either the 4.1.1 or 4.1.2 stock ROM. If you were on the 4.3 stock ROM your root attempt is probably the source of the problem.
IMPORTANT How to proceed from here depends on if you were on 4.3 or an earlier version of stock.

Also, since this forum is for AT&T and Canadian variants; I see the title of the first post says i747 - is this correct? It matters.

ok, not to jack his thread, but what if you are on the 4.3 bootloader? i didnt do what he did, but i am stuck in a similar situation. I am on the 4.3 bootloader, but i do have a custom recovery installed. problem is i get an error when i try to wipe. Ive tried flashing stock 4.3 rom via sideload in stock recovery, and modified rom though twrp. both roms install fine, but dont boot, but they do freeze in different points so i know something is being flashed. ive also tried wiping in cwm and stock. im bout ready to flash anything to this phone. oh and a nandroid restore fails after boot img flashes.

From your message, you likely were on stock 4.3. Since you are able to get into recovery and download modes, you may try a restore via custom recovery. Please see the thread below on how to install custom recovery and do a stock restore ...

I would then link you to the same thread Larry2999 provided.

Yes the phone is AT&T and more than likely it was on 4.3 now what do i do

FuTuRisTiC Zo3 · Mar 12, 2014

Before doing anything else, boot into recovery. If you are on a stock recovery the very first line will tell you that the system recovery is 3e

If you have one of the custom recoveries it will be different. If you have one of the custom recoveries, TWRP or CWM, you can use the link Larry299 posted earlier in this thread to restore your phone. If you are on the stock recovery and the 4.3 bootloader I don't know what to suggest.

I got everything back to normal im rooted on 4.1.2 and have a pending up date, is it safe for me to update via software updater or do i have to do something else

There is a chance that being rooted will prevent you from using the OTA official update. I've seen reports of people being able to update to the official 4.3 while rooted, but I've also seen reports of people not being able to update.

Before you make that update, bear in mind that the official 4.3 bootloader, its name ends in MJB, is the one that will prevent you from ever going back to an older bootloader. Some of the devs and the more experienced on here have no problem with that. Others do consider it an issue. An alternative is to install the leaked 4.3 bootloader, it's name ends in MJ2. That bootloader will allow you to downgrade to the 4.1.1 or 4.1.2 bootloaders, or so I have read. There is information about this in the development and the general forums for our device.

To muddy the waters more; if you intend to sim unlock your device without gettings codes from your carrier you need to do it from the 4.1.1 official ROM. A point you can not return to from the official 4.3 ROM, or so I've read.

I am having a huge booting issue with my Samsung Galaxy S3. Its a brand new one and I tried rooting it but it gave me this error:

<ID:0/003> Firmware update start..
<ID:0/003> SingleDownload.
<ID:0/003> recovery.img
<ID:0/003> NAND Write Start!!

<ID:0/003> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)

I can get to download mode, but not recovery nor does it boot into the Android OS. I tried putting back the stock OS and it gave me this error:

<ID:0/003> SetupConnection..
<ID:0/003> Initialzation..
<ID:0/003> Get PIT for mapping..
<ID:0/003> Firmware update start..

I've tried follow a bunch of these threads, but I can't seem to resolve my issue yet. I probably have that 4.3 bootloader which screwed everything up. Can someone help me resolve my issue? I literally got this phone today from AT&T. Thank you.
