my phone is a little buggy so i wonder should i flash a new firmware or just factory reset it? if i flash new firmware i should reroot, but if i factory reset my root will stay right?
My Nexus 9 which is completely unmodified (Bootloader unlocked, stock recovery,no root, no custom ROM) had an upgrade for 5.0.2. So I clicked OK and then after the upgrade it got soft-bricked.
I tried clearing the cache in the recovery and even a factory reset but nothing helped.
What helped me in the end was flashing a factory image of Nexus 9 5.0.2. So if anyone has softbricked Nexus 9 due to faulty upgrade and a factory reset doesn't fix it then please flash the factory image.
On the same note, my Nexus 9 still has not received the OTA 5.1.1 upgrade. Does it have anything to do with the fact that I manually flashed the factory image on my Nexus?
i have xt912. i installed lineage os 13 on stock slot. i did that by doing a factory reset in safestrap recovery. But that seemed very slow. Now i want to install mokee 6.0 rom. what partitions should i wipe. Should i wipe system+dalvik+data+cache or should i do data+dalvik+cache (factory reset) .
i have read on some threads that system should not be wiped. What is the reason for that?
Is anyone having similar problems. I have flashed an open kirin rom. After that I haven't been able to factory reset the phone using the stock recovery and it keeps looping. The factory reset option seems to be blurred out and I can't access it
What should I do in this scenario ?
TIA
Do you have flashed recovery_ramsdisk with Magisk?
In that case, you may have to restore the stock recovery
When I trieed, I noitced that eRecovery boots Recovery to factory reset and wipe. Which was not possible with the falshed magisk....
Good luck,
Peter
