History in brief: Initially on stock B882, flashed to B892 (stock), then B927 (leaked stock), then B936 (stock), now on official stock B952. Never a single problem during flashing. After each flashing I (re-)rooted the phone (via adb), just in case.
A few days back I tried to flash Dazzozo's CM10.1 via (stock) recovery. No success. I read that I needed CM recovery. So, tried to flash CM recovery via fastboot - upload to phone went fine, then "no permissions to write the image". Same result with other third-party recovery images. Tried to "fix permissions" using ROM Manager, but all I get is an error message.
Reflashed stock B952 - the process went smoothly as always.
My uneducated guess is the bootloader is locked - but have no way of confirming or denying this. Attempts to unlock the bootloader using unlock scripts fail with the same "writing error" message.
I have no idea what to do now. Shall I downgrade to GB and then try to install CM??? Sounds crazy.
Any advice/help would be warmly appreciated.
