Huawei p9 lite firmware update doesn't have effect after successful installing
My p9 lite is VNS-L22C706B120. I never upgraded it since I bought it in New Zealand, though I have received notification of updating to B130 for a long while.
Recently I tried updating to B130 in order to get Android 7 finally, but got problem that the successful update takes no effect at all. I still remain at B120 and keep receiving update notification to B130. I described my steps recently as below:
- Try Updater
First of all, I tried using Updater downloading the package and install, it says update failed because the package it not found. I found the reason is the update package is stored in internal storage other than SD card. Then I created dload folder and moved update package to SD card, but Updater cannot detect it and keep telling me to download B130. Therefore, I tried pressing Volume Up, Down and Power button together. Then the package is detected and installing started. It is very fast and I was told install success. However, after rebooting I still have B120 and am told to update to B130 by Updater.
- Unlock bootloader and root
Yesterday, I decided to try custom ROM, so I managed to unlock the bootloader, install TWRY and root the phone, though I still cannot make B130 update take effect. I searched for a few custom Rom with Android 7, but I found they still required a higher firmware version than B120, like , which requires EMUI 5.X.
- The help I need
I wonder if I can flash the ROMS that require a higher firmware version when I only got B120 firmware. If I cannot, how can I get my firmware updated, through Updater or any other way (like TWRY possibly) ?
I hope I have stated my problem properly so that you guys can understand. I appreciate any suggestions!
