[Q] OTA Update dependence on Stock Recovery
I am in need of a stock recovery for 4.06.651.4 as I want to update my stock+ 4.06.651.4 to the OTA 4.06.651.9 update. I have stock recovery .img's from previous versions but not for 4.06.651.4.
Currently, I just flash the 4.06.651.4 unmodified firmware then apply the OTA 4.06.651.9 update. Following that, I flash twrp. This method works but seems/is kind of a waste of time.
Q - Where can I find a stock recovery for 4.06.651.4?
Q - Is there a tool/method to create a "stock recovery.img" from the installed unmodified firmware? I am willing to write one.
Q - Does anyone know if older versions of the "stock_recovery.img" are compatible with 4.06.651.4?
Thanks in Advance...
