Instructions

Detailed video on the process. Its displaying the process on a Sensation, but its pretty much the same thing. Thanks to kgs1992 :)

Boot the linux box and download the appropriate package for the device.

Extract the package in the home directory

Open up a terminal

Remove SIM, microSD card and battery and connect the device using the USB cable. This procedure must be done without battery

Detect the device using the script provided. Type this in the terminal

./brickdetect.sh

You should get something like sdX. We are interested on that "X"

Unplug the usb cable from the device

Backup the hboot currently in the phone by using this command. Plug the device in ONLY when asked to

sudo ./emmc_recover --backup b_hboot.img --device /dev/sdX12

Replace the "X" with the letter the script gave you

Follow the on-screen instructions from emmc_recover

Hexdump the b_hboot to check the hboot version

hexdump -C b_hboot.img |less

The output should be like this:

00000000 05 00 00 00 03 00 00 00 00 00 00 00 00 00 10 40 |...............@|

This is the typical hex of a hboot. We are interested to check if that is the hboot partition and if it is, to get to know the version. In this case it is 1.90

If in the above step you failed to identify the hboot, unplug all devices connected to that pc, reboot and try again

Unplug the device

Check again it is the right version, because if you do a mistake here, you won't be able to go back

You can only flash the same version as the one in the device.

!!!!!DO NOT ATTEMPT TO FLASH ANOTHER VERSION OR DOWNGRADE!!!IT HAS BEEN PROVEN FATAL!!!!

Flash the hboot on the device. Replace "V.VV" with hboot version (eg. 1.90, 1.93) and "X" with the one you got from the detect script. Plug the device in ONLY when asked to

sudo ./emmc_recover --flash rubyV.VV.nb0 --device /dev/sdX12 --backupafter hboot_f.nb0

Follow the on-screen instructions from emmc_recover. A successful flash should have this output:

511+1 records in
511+1 records out
1047808 bytes(1.0 MB) copied

Unplug the device, put SIM, microSD card and battery in and power on

Congratulations, the device is unbricked.

FLASH THE RUU IMMEDIATELY AFTER RECOVERING!! The device will be unstable after the recovery if you don't flash it.

Notes on the procedure:

​

If the device doesn't power on, get a copy of the hboot_f.nb0 and b_hboot.img (should be located in the home directory) and contact us

The connection between the device and the pc will be unstable, and will time out. You have to be quick when doing the above, specially while flashing. If the connection times out don't panic, just unplug and replug the device

Unity and automount are known to cause issues in ubuntu 11.04 and 11.10. We recommend getting rid of both, or use a 12.04, or 10.04/.10 liveCD

USB3 ports do not work properly. Please plug the device in a USB2 port

How to disable automount on ubuntu

gsettings set org.gnome.desktop.media-handling automount false
