Successful unrooting Tecno CX to take up OTA Update
(01-12-2017, 12:00 PM)dalid.daud Have any one been able to unroot CX and take up ota update without flashing stock rom. I failed, everytime there is ah update am forced to flash stock rom and restart updating version after version till reach the latest.
I root using option 1 as provided on this link https://www.hovatek.com/blog/choosing-ap...a-updates/

(02-12-2017, 07:41 AM)dalid.daud I have read it and it mainly focus on re flashing stock boot, recovery and system. From my understanding, for instance, my cx will take me to version 107 which is 5 OTAs away from latest V159. This is what I was trying to avoid, I want if I want to unroot I should do so but have same v159. I don't know if my point is correct. What am trying to avoid is the cost of data to update from v10u to v159. Last time I only tried to flash stock boot and recovery only and it didn't boot it stopped at tecno log. At that point the only way out is to root so asto patch boot.img. Thus being back to rooted device, no work done!

(03-12-2017, 11:59 AM)dalid.daud I understand using fastboot boot recovery.img doesn't remove stock recovery, but am not sure what else get altered in the system that you can't take up OTA. Because last time I did OTA failed too.
