Very confused trying to upgrade to Gingerbread with IMEI mismatch
At this point, the directions in this thread are too telegraphic for this poor technology-challenged but willing learner...
I managed to root and unlock my Captivate and upgrade from Eclair to Froyo long enough ago that I don't remember how I did it all (Odin one-click figured in, I think), but I now have an IMEI discrepancy, so when I tried to use Kies Mini to upgrade to Gingerbread, no joy, and of course OTA is impossible.
I don't know where to start. I have TiBU, busybox, various SGS tools, and astro file manager among other things. I THINK the firmware's just stock 2.2 (baseband I897UCKB1, Kernel version 18.104.22.168, build FROYO.UCKB1) now, but when I put in the "secret code" for IMEI, it doesn't match what's under the battery, and the product code is also hash now.
So...which of the many threads and alternatives applies to my situation? Do I need to clean up the nv_data file (it looks like there is a backup /mnt/sdcard/nv_data.bak, and if that's NOT a backup, what do I do? there's also a folder /mnt/sdcard/Galaxy_S_Unlock with nv_data.bin and nv_data.bin.unlocked and subfolder /efs that also has an nv_data.bin, among other things.
I'm not trying to flash super-duper ROMs, just get to stock Gingerbread. No need to reinvent the wheel for me - just point in the right direction because the terminology's getting beyond me!
