Sorry I'm a little confused where can I find a samurai kernel for cm9 beta 3? :)
[Epic 4G Android Development] ÜBER™:
The cm9 host mode thread... but there a few commits not included and I dont know if anything changed... you can flash it... and it should boot... I don't think there were drastic changes. Other than one menial tweak. And a few regarding dvfs.

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

install-eng.bat

for Linux with the rights of root

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:

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

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!!
[Acer Iconia Tab A100] Euclid's Brother:
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.

Finally got it after about an hour. I feel kinda dumb but I forget that the Iconia's volume buttons are inverted compared to other devices. And what I ended up doing was wait for the bootloader screen, held down on the left volume button and quickly pushed down on the right volume button.

Thanks to everyone in this thread!

changing bootlogo?

I've taken a look around and haven't seen this brought up - has anyone attempted to change the bootlogo (not boot animation, rather the logo from the bootloader)?

Skrilax_CZ, from the a500 forum, posted a tool for changing the bootlogo for his bootloader, not sure if that was also attempted here?
[Acer Iconia Tab A100] pio_masaki:
No ones tried it because unlike them we have no nvflash, if we jack it up we're bricked, not worth the risk. Its also an a200 boot loader used for unlock. Its been brought up but I'm sure its buried somewhere.

Sent from my Nexus 7 - JBSourcery 4.1
[Acer Iconia Tab A100] mixednuts:
Thanks for the reply. Sorry, did you mean it's been brought up in the a100 forum, or the the a200 forum, before? And, like the a500, the a200 makes use of nvflash for the bootloader?
[Acer Iconia Tab A100] pio_masaki:
Its been brought up here, we just happen to use their boot loader. Nvflash isn't needed to flash a boot loader, we can whenever we want, its for when we screw up the boot loader and recovering. If you mess up the boot loader without nvflash you're bricked, period.

Wrong a100, but if adb works then try adb reboot bootloader if you want fastboot.

Aside from that, its up to whatever dev community there is for that device, I've never heard of it.

[Acer Iconia Tab A100] pio_masaki:
its denying access to writing the bootloader to unlock so you don't have root access yet. Root, or check you have root, first. There's a version for old and a version for new, try the other version, if one didn't work.

No, I'm getting just nothing. No icons after flashed bootloader. Cwm is just overwritten by bootloader when trying to enter which means the bootloader is not flashed...

I flashed also the patched bootloader v3 from thunderb8r project (a500) which was suggested I another blog.. All steps done, CPUID and SBK received, apx mode entered and flashed the bootloader. But it is still the same bootloader...

These may sound like dumb questions, but I'm just trying to help. You are rooted and on official ICS? And are you using the process on windows? If so when you run the windows batch file your tab reboots,but no lock/unlock option?

Also you are saying CWM is getting over written? How did you get CWM on it in the first place

When you boot the green acer logo is not in the center of the screen

.

Also in the second picture the acer logos is on the bottom and on the top from the screen the signature distorted.

Is there a possibility to replace this pictures?

I now is the bootloader for the a200 therefore the wrong size...

_______________________________________________________________________________________________

Another question:

When you open the Fastboot&Recovery.zip it gives files for the a100 and the a200.

And when you open the install-eng.bat will only access the files for the a200.

Does anyone know what happens if I replace the a200 command line against the a100 command line in the install-eng.bat?

There are in the zip folder files available for the a100.
[Acer Iconia Tab A100] pio_masaki:
If you run the a100 version it relocks the boot loader. He really should have made this clear, but running that and having a custom recovery and ROM bricks the device, it will not boot with no way back.

Tapatalked from my HTC DNA - ReVolt
[Acer Iconia Tab A100] frischeis:
Okay thanks but,

when i use the zip with a non modified tab (only root) with the a100 file version it will fit the boot pictures to the right size?

Another thing: In the original thread they use the install.bat not the install-eng.bat, is there a diffrent?

The main reason why i ask is they i have a clean starting screen during booting.

I now the important part is that the bootloader work correctly!
[Acer Iconia Tab A100] pio_masaki:
The unlocked boot loader is for the wrong screen size son it distorts, if you're just rooted then the a100 boot loader is there and it looks correct. Its one or the other, either unlocked and distorted or clear and locked to factory.

Install and install-eng is the English version of the script.

Unlocked distorted = custom recovery and ROMs

Locked clear = only factory recovery and ROM and root.

Putting the a100 boot loader back on with a custom recovery and rom will brick, I can't stress this enough. Stop messing with the boot loader.

I have a another bear:

I get a tablet from a friend with a problem that the tab not boot.

It stuck on the green acer logo with the message on the left upper corner:

"Bootloader version 0.03.06-ics (unlock mode)"

And nothing happens.

------------------------------------------------------------------------------------------------------

When i go in the recovery with holding the buttons i get this message:

"Bootloader version 0.03.06-ics (unlock mode)

Erasing cache before sd update...

Sd update cmd: recovery

--update_package=SDCARD: update.zip

Booting recovery kernel image"

And nothing happens.

-------------------------------------------------------------------------------------------------------

My question: Is it bricked?

It locks like the recovery kernel image is corrupt?

I try to install by rename a custom rom to update.zip to install them with holding the buttons but nothing happend.

Is there help or can be disposed of it right? :silly:
[Acer Iconia Tab A100] pio_masaki:
Remove all update.zip files or it'll bypass cwm and twrp and they to run it which may be happening now, it will only work on official packages, not custom ROMs.

In fact, remove the SD card completely and they to boot recovery and report back if its cwm or twrp or stock recovery. If its stock then fast boot a recovery onto it. He may have attempted to install a stock ROM which causes these kinds of issues and tends to lock the device out.

Tapatalked from my HTC DNA - ReVolt
[Acer Iconia Tab A100] frischeis:
Thanks for response!

The big big problem is I do not come into the recovery.

It depends on the green acer logo with this message on the screen:

Bootloader version 0.03.06-ics (unlock mode)

Erasing cache before sd update...

Sd update cmd: recovery

--update_package=SDCARD: update.zip

Booting recovery kernel image

and nothing happend....and i cannot boot to android.

When i want to boot android it depends too with the green acer logo and this message:

Bootloader version 0.03.06-ics (unlock mode)

Any ideas?
[Acer Iconia Tab A100] pio_masaki:
Yeah, do what I said, remove the sd card. It's bypassing any attempt at recovery because its sitting there trying to run update.zip, which is NOT what you want it doing right now. Eject the card, then try recovery again. Don't even think about booting android yet, get recovery working FIRST then you can worry about the rest.

If it boots recovery without the sd card, then do what I said, again, and delete anything that says update.zip on that card, then report back and we can move on to the next step.
[Acer Iconia Tab A100] frischeis:
Recovery will not load!

Thats the big problem!

SD card is out of tab.

I get the message as in the previous post:

Bootloader version 0.03.06-ics (unlock mode)

Erasing cache before sd update...

Sd update cmd: recovery

--update_package=SDCARD: update.zip

Booting recovery kernel image

Thats the problem...
[Acer Iconia Tab A100] pio_masaki:
OK you never said you did it, just said what had said before. Is fast boot still an option? Boot holding the other volume button down, I think its the one furthest from the power button, volume down in portrait. Been awhile, just use the other volume instead.

You can try but if there's no partitions there's no place to flash to, and if it does, it won't mount them to read from.
[Acer Iconia Tab A100] frischeis:
I think the fight is pointless.

Last idea:

Would the stock bootloader works?

After flash that I could install stock rom "update.zip"?

Or is that thinking for nothing??

I'm giving up slowly ....
[Acer Iconia Tab A100] pio_masaki:
Same thing, no partitions to flash to, or read from, and putting the stock boot loader on now would lock the device up and brick it anyways.
