[How to] Install unlock bootloader for A100/… |

Original article is published on this site and created by ZeroNull and vdsirotkin (4pda.ru).

WARNING - If it works on your device, be careful, as with an unlocked bootloader you can brick you tab faster than you can imagine.

How to:
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:
for windows with the rights of administrator

Code:

install-eng.bat

for Linux with the rights of root

Code:

bash ./btl-a200.sh

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:

Code:

sudo fastboot reboot-bootloader

And you'll get the message on the screen when it comes up in fastboot mode.

Code:

"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

Code:

bash ./btl-a100.sh

PS: After unlocking bootloader there is a noncritical distortions of the picture at a stage of initial loading.

Hi there,

First off, great work. Just tested this on a100, once I re-read your post and I ran the a200 named script first it worked fine, I assume this is method shoehorns the a200 bootloaded into our a100s?

Excellent work, this means a lot!!

oh nice! I assume, if you could use the a500 patched bootloader as well, yes? That one is actually the same version as the A100 ics bootloader.

Thanks for the script.

I thought as much, hearing that the A200 bootloader is unlockable. Any word on a custom recovery? Perhaps we could roll our own Clockwork?

Would you be looking into CWM 5.5 or 5.8 (touch version)? I ask because after using it on my Atrix, I think the latest version is far better than the old volume rocker navigation.
