- flash the original stock rom. The file is called KIES_HOME_L900VPALJ1_L900SPTALJ1_265523_REV04_user _low_ship.tar.md5
I used the note 2 toolkit by skipsoft /w odin to do this. I attempted to download this file from hotfile, but that site got shut down. Find a reliable copy of this file, then use odin to flash this when doing a "flash stock rom" operation.
- at one point, my phone kept rebooting to the samsung logo, and did not get into the operating system, so I thought I was bricked, but your still ok. I had to remove the battery, then re-insert, then force it into download mode with power+down volumme+home button. Then, it magically continued the process at the "upgrading android 1 of x" screen. Then, it will boot up to "factory".
- Now, it it truly factory and ready to accept all sprint provided updates, and yes, all the way to 4.3.
Let me know how it goes.
Actually I have given up trying to get an update because of all the gyrations involved. I have too many apps for any backup program to backup/restore reliably.
I found a thread where someone had posted a method to get rid of the constant upgrade notification. Now I do not get update notifications. I will stay on 4.1.2 till I upgrade the phone or a better rooting method is found.
I did consider flashing the phone with CM10 but even their stable builds have problems as indicated by users on their forums. Now that CM has got new funding, hopefully, they will release more stable builds.
