[Q] Having trouble upgrading from 2.3.6 to 4.1.2
I have an ATT Samsung SGH-i727 running 2.3.6.
I tried to update it to 4.1.2 stock ATT with Kies, but Kies did not work; it said it could not contact the upgrade server.
So I downloaded Odin 1.85, downloaded ATT stock 4.1.2, and selected the ROM with the PDA button and pressed start. Auto reboot and Reset time were checked.
An hour or two passed and Odin was hanging on system.img.ext4. It never completed. I rebooted, and now it is stuck in "Firmware upgrade encountered an issue. Please selecte recovery mode in Kies and try again."
I tried starting over in Odin, but it says that the write operation failed when it gets to system.img.ext4.
Any guidance on how to get this working?
P.S. Here is the full log from Odin after trying again:
