[Q] HELP with recovery, no usb access to nexus 7, not detecting with official cable. topic

05:38






Ok so long story short, i have a nexus 7 2012 which a rooted and installed cyanogen mod.
I was using it as a car install and works perfect, i'm using an otg cable to mount usb sticks, triggering soft shutdown and powering the nexus etc. So usb seems to be working fine.

Basically i removed the tablet it to modify the bootloader to turn on automatically with ac power applied, if the battery runs out i have to manually power on with button, but now i'm running into a problem.

Ever since taking the tablet out and trying to connect over usb, none of my computers detect the tablet.
I've tried different operating systems, drivers, cables etc etc.
Also changed from mtp to ptp in storage and also turned on usb debugging mode. If i connect an otg cable the nexus see's the otg and i can mount usb's etc.

So i thought i might try recover the nexus back to factory, maybe there was an issue with the rom corrupted etc, I've downloaded the original 4.2.2 firmware which is currently installed.
Booted into recovery and tried re-installing the 4.2.2 zip, it keeps aborting. A guy in work tried to use sideloader and connect via adb. no luck.

I'm not very familiar with the android platform so i've no other ideas what to do and other idea's how to recover now.

The guy i work with mentioned using a usb jig, would that be the way to go or can anyone else suggest some else that might help.

Thanks
