WARNING - If it works on your device, be careful, as with an unlocked bootloader you can brick you tab faster than you can imagine.
0. It has been tested on the A100 ICS firmware. This bootloader doesn't work with HC firmware.
1. The tablet should be already rooted and charged more than on 30 %. Сonnect the tablet to the computer and power on.
2. Download this
archive. Unpack it to any place.
3. Open the directory with the unpacked archive. Execute file:
with the rights of administrator
with the rights of root
4. Wait. The tab will show a screen with two icons. One for lock and on for unlock. I used the volume down to highlight the one I wanted and the volume up select it.
Then you have to reboot, using, for example, this command:
sudo fastboot reboot-bootloader
And you'll get the message on the screen when it comes up in fastboot mode.
"Bootloader v0.03.06-ICS(UnlockMode): Starting Fastboot USB download protocol"
It's unlocked and available for fastboot flashing, etc.
For return original bootloader:
for Linux with the rights of root
PS: After unlocking bootloader there is a noncritical distortions of the picture at a stage of initial loading.
