HTC One SV In boot loop topic

Hi all,

I've a friends HTC One that is stuck in a boot loop cycle, and I'm trying to fix it for them. I have unlocked the device via htcdev.com.

Action: Power on device
Observe: "HTC quietly brilliant" boot logo. Logo remains on screen for approx 10 seconds, then screen goes black and logo reappears. Repeat x n.

I started by following these instructions: http://forum.xda-developers.com/show....php?t=2113671

However, I can't "Move the Superuser.zip to somewhere on your phone's SD card". The device is never recognised as a storage device.

Some fastboot output:

However, if I enter the bootloader and select "Recovery" I'll see the HTC boot screen with "Entering Recovery" at the top. This screen never changes.

I've tried both the CyanGenMod recovery file and the TeamWin file. Both give the same results.

Any advice?
