HTC ONE wont turn on
I've bought the phone today.
It's in mint condition, lcd isn't cracked.
It won't turn on. I've tried to reboot it, it didn't help.
Back and home button is blinking when i release power button.
I've entered to fastboot blindfold with keys, flashed RUU 4.4 rom, that didn't help. But it gave something - phone produces the power on sound.
PC detects it as default - MTP device.
Now it's charging - led is lighting.
What should i try?
i don't think that the lcd is the main problem - it looks like new. i've disconnected it from the housing - no any signs of damage.
