I'm currently on CM11 (nightly and TWRP) and want to revert to stock. Kies has the "Firmware upgrade and initialization" option ..
My question is:
Is it necessary to reset the flash counter in order to use this? What will happen if I try to use it without resetting the counter?
I tried to find an answer for the last few days, but couldn't (or couldn't understand what I found).
The backstory is my serial number was reset and I can't connect to network after flashing ArchiDroid with a new modem. I afterwards flashed a different (JB) modem. I was already on Samsung stock 4.3 so I guess my efs is v2 (so no Ariza's patch..), and I have some backups of it.
I'd rather not use Odin or ADB. I figured the easiest and safest way is to reset and restore everything to stock, send to a lab if necessary, then reinstall cm11. I'm also not sure how restoring the efs works ..
I'll be very thankful for any feedback, as I've been wasting a lot of time on trying to solve it recently ..
