Hey guys! I have a question. I'm currently having a problem. I don't know what to do in order to update to Android 4.3 on ky GS3. My phone is rooted and I have a custom rom. From what I heard, I have to unroot and put back the stock rom and I guess I should put back Android 4.1.2 hence my custom rom is based on 4.1.2. Can someone please explain step by step what I should do in order to update to 4.3? Thanks in advance!

Well it depends on what style of android are you looking for, a stock android look like the Nexus phones have or a Samsung Touchwiz.

It depends on you (as for me I wanted to go back stock so I cleared the flashcounter as well)

THIS WILL WIPE YOUR INTERNAL STORAGE ! ( loose all apps and stuff )

A) If you don't care about the flashcounter

- Just download Odin 3.0.9 http://forum.xda-developers.com/show....php?t=2189539
- I downloaded I9300XXUGMK6_I9300OXAGMK6_OXA which is a clean 4.3 UK NO Bloatware firmware ( if you need a fast Mega download link PM me )
- Open Odin3 v3.09
- Restart phone in download mode (Press and hold Home + Power + Volume down buttons)
- Connect phone and wait until you get a blue sign in Odin
- Add AP_I9300XXUGMK6_2168382_REV00_user_low_ship.tar.md 5 to AP
- Add BL_I9300XXUGMK6_2168382_REV00_user_low_ship.tar.md 5 to BL
- Add MODEM_I9300XXUGMK6_REV02_REV04_CL1413323.tar.md5 to CP
- Add CSC_OXA_I9300OXAGMK6_2168382_REV00_user_low_ship.t ar.md5 to CSC
- Make sure re-partition is NOT ticked
- Click start button, sit back and wait a few minutes.
- If you encounter any issues with the firmware (Any FC, Bootloop etc)
- Boot into recovery mode (Home+power+vol up)
- Choose to wipe/factory reset. (THIS WILL ERASE ALL OF YOUR DATA INCLUDING YOUR INTERNAL SD CARD!)
- Then choose reboot and you should be good to go!

B) If you want to have Official ( so you can send it back to Samsung if you still have warranty )

- Just download Odin 3.0.9 http://forum.xda-developers.com/show....php?t=2189539
- Search for your 4.1.2 firmware http://forum.xda-developers.com/show....php?t=1646610 or on Google, download it.
- Extract the zip you downloaded so you will have a the .tar.md5 on your desktop or where you extracted it.
- Open Odin , and click on AP and select the .tar.md5 you got from the zip.
- Restart phone in download mode (Press and hold Home + Power + Volume down buttons)
- Connect phone and wait until you get a blue sign in Odin
- Make sure re-partition is NOT ticked
- Click start button, sit back and wait a few minutes.
- If you encounter any issues with the firmware (Any FC, Bootloop etc)
- Boot into recovery mode (Home+power+vol up)
- Choose to wipe/factory reset. (THIS WILL ERASE ALL OF YOUR DATA INCLUDING YOUR INTERNAL SD CARD!)
- Then choose reboot and you should be good to go!
- Then you must root the phone again,
- Use the Triangle Away app
- Reset the flashcounter and from there just follow the steps from A)

Hope it helped you

Yes, and you don't have to choose the one for your country. You can you any firmwork you want. My phone came with XEF ( France ) but I live in Romania and currently I have a UK one and there is no call or mobile network errors.

Thank you! I live in Romania aswell. I was thinking on flashing the rom for Switzerland. I heard that it is one of the best 4.3 stock rom's.
