[HTC One X] vantt1:
My HTC One X's bootloader refuses to be unlocked. No matter how many times I get the Unlock_code.bin, the result is the same. I see the screen prompting you to unlock, the phone restarts, but the bootloader is still locked! It always says "FAILED (status read failed (Too many links))", as shown in the "code" below, and when I try to go into recovery, I just end up in the bootloader again.

I've tried rebooting, powering off, and unlocking the bootloader at least 20 times.

Please help!!

UPDATE: The HTC One X is now stuck in APX mode. I've installed NVFlash drivers and got the NVFlash tool, but executing "nvflash --sync" gets me this:

D:\HTC One X>nvflash --sync
Nvflash started
rcm version 0X4
Command send failed (usb write failed)
