Anyone can help me here? So my HTC 10 is the international unlocked version. I bought it from Amazon US and use it in Indonesia.
It worked really fine for more than a month but today something happened.
I turned off the phone and replace the SIM card. When I powered up, it shows only black screen with white htc writing in the center and "powered by android" at the bottom. After a while, there's no change other than the screen turned brighter. It stopped there.
Usually, the normal start up would be green htc logo, and some circles making movement and shapes.
I managed to get into the bootloader screen (volume down, plus power button. And as the logo disappeared, release power button and then press volume up).
Tried to choose reboot, still the same. Tried "reboot to bootloader", it gave the same response as "reboot". Tried "boot to recovery" : nothing significant happened.
Tried "boot to download" : everytime I hit a menu, the screen showed the message that it did the command, but nothing happened after 5 minutes.
Tried to power down, and then charge, the battery percentage didn't show any increase. but it actually charged, because after I entered bootloader and powered off again, charged and then it showed the percentage change. But still not increasing from that later level. And I also couldn't powered on after charge. I had to press volume down and power, to get any response.
What should I do? I suspect major software breakdown even impacted the bootloader? What files can I download (I still confused between RUU, ROM, firmware) to restore my phone. Hopefully it can be done without having to unlock bootloader etc.
Right now it's still "LOCKED", "S-ON", "Software status : Official"..
I just want to restore.. Older firmware will be no problem, as long as it can function normally again and I can update OTA from thereon.
Thank you
