Default [Q] Black screen, no USB debugging

Hello everyone,

I hope someone can help me with this.

My uncle brought me the HTC One X yesterday and it didn't run at all. So I charged it whole night and it showed glimpses of life this morning. However the screen is black, there are sounds and I see touch buttons flashing. I don't know if there is lock screen at all, and probably USB debugging is not activated. Yet there is no HTC service shops or something like that so I'm on my own. I've looked everywhere and it seems nothing helps.

P.S. there are probably some grammar mistakes but hopefully you can forgive me.


When I connect my mobile phone to computer via USB cable and HTC Sync Manager pops out it says that my phone is locked and I need to unlock it.

Default Remove Sim

If there is a sim inserted in the tray, remove it.
Charge it for about 3 hours, hold down the power button and volume down for about 10-15 seconds.
If you could get into fastboot then its definitely a problem with the OS. (Locked may be).

Im not quite sure of it. But you could try.
