[Q] Downgrade to root

[Manneman32]

I have spent the day to figure out how to root an S3 with 4.3.

I´m no stranger to flashing but I get confused with all the threads and all the links, stickies and "how to´s" all over the forum.

Can someone please link me to the proper stuff I need?

* I know I have to downgrade via ODIN to be able to gain root and thereby get a custom recovery. But to WHAT version do I need to downgrade to? 4.1.2? 4.2.2?
* Is there an absolute STOCK deodexed 4.3 prerooted firmware that can be flashed after gaining root and custom recovery.

Just to make myself clear... the searchfunction has not been working today, so I have been making my searches via google... and that can be a bummer when looking for some handson instructions.

Can anyone be a gent and provide me with some links?

Best regards

Just flash a custom recovery with odin (I'd suggest philz) then the rooted 4.3 stock rom, you don't need root to do this. Chose the stock rom from several in the general forum.

Really? That easy? Great news!

Just a question... I have to flash the custom recovery and the flash the rooted 4.3 ROM before first boot? I have to enter custom recovery directly and flash the new ROM? Or can I boot the phone with just flashing the custom recovery, and then take my time finding a good ROM while running the stock 4.3...

Sweet jesus... I have been away for too long, damn Windows Phone

Stock rom flash recovery via Odin that's all .
= rooted stock
Custom rom is then flashed whenever via recovery .

You may find that a stock rom will restore stock recovery on first boot, so you may need to flash your new rom straight away.

You could also root your existing rom just by flashing CF autoroot.

Well... everything went fine!

PhilzTouch via ODIN and after that a good 4.3 stock ROM. Just as mentioned above I just had to make sure in recovery that the custom one wouldn´t get overwritten.

I made a full backup... I have also saved that backup om a HD on my PC. However... when I made a backup of my efs-folder I couldn´t find the backup file efterwards. Not even as a hidden file. I choose to make the efs-backup on my SD-card. Any idea where to find it?
