[Q] Hard bricked G2 won't appear in /dev/sdb* on linux topic

I was trying this to fix a hard-bricked G2 I just recieved:
http://forum.xda-developers.com/show....php?t=2582142

The device is in the following state:
No download mode
No recovery mode
Shows qhsusb_bulk in lsusb -v
I don't know much more about it (e.g. I don't know if it was rooted or what type of ROM was on it).

I need to unplug the battery by removing the back cover to have a chance to reboot it. The first boot after that it shows the LG logo, then a blank screen (back lit but no text).
(UPDATE: Pressing the power button 8 seconds also reboots the phone without having to unplug the battery).

When I wire it up to my Arch Linux computer here is what the command `dmesg` shows:

Code:

Note the "config 1 has an invalid interface number: 20 but max is 1" error, and all the Buffer I/O errors.

Here is the relevant section of `lsusb -v`

Is there anything that could be done to fix these Buffer I/O errors so I can mount the phone (and continue with the FIX tutorial posted above)?

Anyone able to shed some lights on the meaning of these lines would be of great help in my quest of learning how to unbrick my phone.

Note: when connected to the computer the blank screen goes in a repeating cycle of being back lit for 1 second then no backlights for 1 second. The cycle stops (with backlights) when unplugging the phone.

Linux on the Nexus 9. topic

I'm wondering if anyone is interested in a guide to getting Linux running on the Nexus 9.
I've got a base system running with fbdev as a rendering output. With a bit of work I'm sure someone could get Nouveau running as a hardware accelerated video driver.
I posted a tweet with an image of it running Ubuntu core + i3 window manager.

Do people have enough interest in this for me to write up a guide?
