A little under a week ago, we talked about how Android 4.3 (I9505XXUEMJ5) was starting to roll out for the Samsung Galaxy S 4. Thankfully for those averse to waiting, XDA Recognized Developer Faryaab mirrored the update and gave users instructions on how to use Odin to flash the ROM image. Unfortunately though, some users updating from Android 4.2.2-based custom ROMs have had their share of issues ranging such as bootloops.
To help users who are currently experiencing problems, XDA Senior Members Degrated Shadow put together a list of three device scenarios, each with steps on how to proceed. These include: unrooted 4.2.2 and official status with old bootloader, pre-rooted stock firmware, and rooted with custom ROM or PIT. Instructions for those coming from a custom ROM or PIT make use of XDA Senior Member S.a.M.e.R_d‘s version of CWM and XDA Elite Recognized Developer Chainfire‘s Auto-Root.
If you’ve been experienceing issues while updating to Android 4.3 on your Galaxy S 4, head over to the troubleshooting thread.
