My OPO(One plus one) with cyanogenmod (last update in August 2016) purchased 2.5+ yrs back, is not starting when it is connected to USB or starting to fastboot mode when it is not connected. It is happening from last 3 weeks only.
When it is in fastboot mode, I connect it to my PC and run command
fastboot continue to resume the boot and it starts. But I need to do it everytime.
So I have
wipe cache partition and then
full factory reset. But I can see that the problem still persist.
I have installed TWRP now. But it din't solve the problem too.
- If I install some custom ROM, would it solve the problem?
- Why fastboot mode comes everytime while there was no update happened recently?
- Can it happen due to some hardware issue? (I actually put a cup of hot tea on back of my mobile for a min .... :( )
:: Update ::
I have installed LineageOS. But still facing the same issue.
