Unfortunately your best bet is service.

But they can send you away as your warranty is void.

Try to persuade them to fix your tablet for a charge.
[Acer Iconia Tab A100] sachadesousa:
so its toast? ill just return it to wallmart ;D
[Acer Iconia Tab A100] cindylike24:
When did you buy your tablet at Wal-Mart? I believe that they have a policy that after so long after you buy it, their warranty on it may expire and they'll have you go through Acer's tech support to rectify your issue with your tablet.

How to unbrick A101 when unlocking bootloader?????

Hi all,

Before unlocking bootloader, I was in android HC 3.2.1 and I followed above guide. I am using Windows 7 64 bit so I right -click to run instal-eng.bat file with administrator rights but nothing is happen. So I open instal-eng.bat in notepad to see it's commands then open a command window to enter commands line by line. I do to:

@echo off
cd tools
cls

echo Wait for connecting device
adb wait-for-device
echo -
echo -
echo Prepare...
adb push bootloader.blob.a200 /mnt/sdcard/
adb push wrtbtla200.sh /mnt/sdcard/
echo -
echo -
echo Execute scripts
adb shell "su -c 'sh /mnt/sdcard/wrtbtla200.sh'"
sleep 20
echo -
echo -
echo Rebooting
echo -
echo -
echo Wait for connecting device
adb wait-for-device

Then my A101 is rebooted and I see the Acer green logo and nothing is happen. At the command window, I try to type "adb devices" and see no devices connect... I tried to reboot sometimes but nothing is change :(

Now I can not do anything, so could you please help me to guide me how do I need to do to unbrick my A101.

Thank you very much :confused:

Read the text you quoted. Only works on ICS bootloader.
[Acer Iconia Tab A100] trevor7428:
quick question. In OP it says

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

This is where im confused (haven't tried yet) what does it mean by execute file? like type that code in command propt while connected to a100?

if so, what state of the a100 should it be in? just turned on normally? download mode or hold down power and volume down and navigate to fastboot mode

or am i completely wrong and you have to do something else

any help would be appreciated and thank'd
[Acer Iconia Tab A100] Theonew:
It means to run the file (just double click it, or right click and run as administrator). The tab should be connected to the PC in its "normal" state.
[Acer Iconia Tab A100] pio_masaki:
Can't double click, to be run as administrator you have to choose it. Even logged in as administrator you have to right click and choose that.

adb help

I ran the file using the en and ADB just flashes real fast then disappears. when i try to open ADB on its own it flashes fast then the same gone so fast I cant even read it. I then ran the non en file and it ran fine but I still cant get my adb to stay up in English. So I cant do a back up. I am running win 7 x64 pro. I have eclipse and it in installed on my j drive I don't know if that is an issue. Any thoughts or ideas would be greatly appreciated.
[Acer Iconia Tab A100] labros1995:
guys i finished the process and now my bootloader is unlocked.thanks very much but every time i open my tablet when it starts booting is shows a green acer logo and on the top of the screen it shows "Bootloader v0.03.06-ICS(UnlockMode)" in white letters.is that normal?

That's normal.

Update driver

Update Driver for Windows. Look this.
[Acer Iconia Tab A100] Attictron:
Thanks for the reply but I'm actually on Ubuntu and not Windows. Would the same drivers still work?
[Acer Iconia Tab A100] -DarkKnight-:
dament times out before i can do anything
[Acer Iconia Tab A100] pio_masaki:
No. Find one of the many guides on building from source and it will tell you how to setup for the device to use adb/fast boot. I'll try to edit back the lines but it should be in my cm9 build guide in my sig. The section on USB and android.rules file.

[Acer Iconia Tab A100] Romman0:
You have to be super fast to toggle the unlock, and you might have to hit it a few times to get it to unlock.
[Acer Iconia Tab A100] pio_masaki:
Yeah IMO have your fingers on the volume keys in your lap, hit the script and immediately get ready to hit those buttons as soon as those icons appear. Its like a half second window.

[Acer Iconia Tab A100] ponjanek:
zn mentioned that the unlocked bootloader used for android 4 is not compatible with android 3.2. I have a stock 4.0.3 and would like to down grade to 3.2, due to some functionality lost in 4. Is there a bootloader available? Will the update.zip thats available in the downgrade thread replace the bootloader automatically? If not, could someome make available what would be needed to complete what the the update.zip would be missing to downgrade from a stock 4.0.3.

Thanks much...
[Acer Iconia Tab A100] smokku:
Take a look at the end of the first post:
[Acer Iconia Tab A100] ponjanek:
Thanks for the reply. I'm familiar with zn's procedure. btl-a200.sh moves in the unlocked bootloader and btl-a100.sh moves back the 4.0.3 LOCKED bootloader. I've tried it a few times. It works great. Acer Recovery Manager states that the new ics bootloader is not compatible with the hc. My concern is that using the update.zip without the correct bootloader in place could keep the tablet from booting up. Has anybody out there tried this?

Thanks
[Acer Iconia Tab A100] smokku:
I successfully downgraded my A101 from leaked A100 ICS back to stock A101 HC using standard decrypted update.zip (Acer_A101_0.000.00_2.004.01_EMEA_GB.zip).

So if you restore the A100 locked bootloader first you should be fine with downgrading to HC.
[Acer Iconia Tab A100] Romman0:
Agreed.

You can also flash the stock .014 ics that zeronull released here. That will relock the boot loader and reflash the stock recovery. Then downgrade with any stock 3.2 package. I definitely would not go right ahead and flash a stock 3.2 rom, over what you have now. Sounds like trouble.

Also if your already unlocked and have a custom recovery, why not try a few roms and see if any of them fix your issues.
[Acer Iconia Tab A100] ponjanek:
Thanks smokku and romman0 for some very useful info. I'll try some of the ROMs you suggested.

I'm pretty familiar with UNIX/Linux - the base OS of these tablets - but am new to Android.

One more question: looking through these threads I see the term 'leaked'. What is that? How is that different from the stock released ROM?.

Thanks again.
[Acer Iconia Tab A100] pio_masaki:
They are essentially the same thing however there was one very large difference: The "leaks" were leaked out before ICS was supposed to be released, so in effect we got it because someone managed to get it out into the wild for us to play with. It's unofficial Acer ROMs that were otherwise apparently just production ROMS before they were production ROMS.
[Acer Iconia Tab A100] rldstover48:
hello, I have had my A100 about a month when i got it it was on HC so i just let it run all the updates from acer until getting it to 4.0.3 stock and then rooted it. So i could use TiB and Root Explore

Image ver=Acer_AV041_A100_RV02RC01_PA_CUS1

Build #=Acer_AV041_A100_0.009.00_WW_GEN1

Kernel ver=2.6.39.4+

I am having force close issues with H.A.W.X would like to install cf3d so i can see if i can get it to stay running. In tring to install cf3d I get error cant write to system. In reading up on that error i read cf3d needs bootloader unlock or s-off .

I do not CWM or any other if there is custom recovery installed/flashed.

In reading the OP I dont see that thats a requirement but wanted to make sure before i try this and also wanted to make sure my setup above is ok because in reading this thread there have been those who have had problems and id like to not be one of them,LOL

If i need to Flash CWM or the Leaked ics rom would like to know before i start this. If you need more info let me know also.

Thanks ahead for those that can give me a heads up and keep my tablet untoasted.
[Acer Iconia Tab A100] pio_masaki:
Custom recovery is not needed, there is a specific order and recovery is third on the list;

Root>install and unlock a200 boot loader>install custom recovery > install custom ROM.

Needs that order or it won't work, since you're rooted you can continue to step 2, the bootloader, and stop there if you prefer stock recovery and ROM.

Tapatalked from my Galaxy S II - CM10
[Acer Iconia Tab A100] rldstover48:
Thanks appreciated,
[Acer Iconia Tab A100] Romman0:
I thought .009 was a leak version?

Either way the procedure is the same.
[Acer Iconia Tab A100] pio_masaki:
I hadn't even seen that. But yeah either way its the same game regardless of the ICS ROM you're on. The leak thing is a remnant from before Acer released ICS officially. Leak or OTA, doesn't matter.
[Acer Iconia Tab A100] rldstover48:
ok im tring to do this now and ok up to point of executing bat file and it runs the comand prompt so dam fast cant see whats hapening, i did do the adb devices first to check conection but had to copy all the files in fastboot&recovery into fastboot_recovery to get to i couldnt change directory thru command prompt but nothing happened no screens for unlock lock
[Acer Iconia Tab A100] pio_masaki:
If its opening and closing a prompt in the blink of an eye then it hit an error of some sort. In order to see what that error might be, you need to open command prompt then launch it from with in, so assuming windows

windows key +r enter cmd hit enter (or however you launch it normally)

once in the terminal type

cd c:\whereveryourstuffis

then once in the correct folder, invoke the bat file

batfilenamehere.bat

press enter to run it, and see what it's saying.

For ease of use, I would put in a folder on root, so its like c:\unlock then everything is right there, easy to get to.
[Acer Iconia Tab A100] rldstover48:
Thanks probably won't get another chance until tomorrow but really appreciate help never seen something like this weird how file unzipped and that I couldn't get into the directory with command prompt and couldn't for life of me remember how to key it into the directory this should help I'll post back.
[Acer Iconia Tab A100] rldstover48:
ok i did get back to it it seemed to go thru, when i got to the sudo reboot part it said sudo unreconized command but on tab screen it just said to reboot so i powered off and back on seems to be working tab rebooted is there anyway to check it. while i was on a roll decided to attempt to flash cwm downloaded image placed in the workin folder followed steps no errors seen. whe i try to boot into recovery i get dead android red esclamation triangle. tryed power=volume down and reboot into recovery with TiB. what did i do tab boot fine also bootloader did think i read bootloader 3.06 unlock mode. did i get wrong image
[Acer Iconia Tab A100] pio_masaki:
Sudo is a linux thing, windows won't know what it is. If your script is using sudo then its the linux version.

Not sure what you mean to check, if you mean it did the process for unlocking (the screen with two icons) then you can check on the acer screen, upper left, in white text, will say bootloader whatever version (unlock mode). If it doesn't say (unlock mode) then it's not unlocked. It'll probably say something like bootloader 03.06 ICS (unlock mode). If it says 03.06 ICS but no unlock mode, or locked, you'll need to pass the command for it:

adb reboot bootloader

once the usb download whatever screen appears

fastboot oem unlock

quickly hit volume - then volume +

You have got to be quick, its like a half second window

once thats done enter

fastboot reboot

and the tab will reboot.

Thats basically the manual way of doing it once the a200 bootloader has been pushed in the previous portion of the script.
[Acer Iconia Tab A100] rldstover48:
have a question is the rom im using a old one looking at other numbers i see what you are saying should i be using a different rom and thats why the gameloft game im trying to run force closes in game after a bit, i had another tab that i took back think it was a teki came with ice loaded game worked well on it but the tablet was slow and now got a strang one with cwm not loading, any ideas or help appreciated

---------- Post added at 09:30 PM ---------- Previous post was at 09:12 PM ----------

thanks again all i got it checked at end of the cwm thread and it said something about getting rid of install-recovery.sh file i just renamed it and redid flash backing up now and the sudo thing i was talking about was in the op i guess i was moving to quick but was sure it said befor it windows command. But anyway all went well your all great minds this old man says thnks for being there.
[Acer Iconia Tab A100] pio_masaki:
Glad it all worked out for you. Yeah the instructions seem to mention that install-recovery.sh thing after the directions on how to do it, so alot of people miss it the first time around. You're not the first, or the last :good:
[Acer Iconia Tab A100] :
HELP!!!

I ran fastboot on the a100. It went fine till the two unlock things came out.

Fastboot : Cancelled by user or timeout.

Fast replies would be appreciated.

Edit: Problem solved. I pressed the wrong button. Thanks mates.
[Acer Iconia Tab A100] Theonew:
You need to select the option as soon as possible (try to do it instantly).
[Acer Iconia Tab A100] imamreizafahlevi:
I want go back to locked bootloader, can someone help me? :(
[Acer Iconia Tab A100] pio_masaki:
Run the a100 script instead of the a200 script, however before you do that make sure you have stock recovery and/or stock ROM installed!

You can also run one of the stock rom releases as update.zip (stock recovery, or flash it via custom recovery as normal) and it will replace the bootloader, then the recovery when it boots into android.
[Acer Iconia Tab A100] tennessee_titan:
Dont understand why this doesnt work. Error message says install-eng is not a recognized command or batch file..
[Acer Iconia Tab A100] pio_masaki:
You have to run it from the folder it's in, windows doesn't just know where it's at, especially in a terminal.

unzip this stuff some place easy, like c:\unlock

Open a command prompt

type: cd c:\unlock

type install-eng.bat

it will then run, and follow the rest of the directions.

Alternately you can go to the folder install-eng.bat is in, right click it, choose Run as Administrator. The window will open up, and close when it's finished, however any errors will make it vanish in the blink of an eye, hence my earlier instructions.
[Acer Iconia Tab A100] tennessee_titan:
Finally got it! Problem was wrong directory...

Thank you!

The step cd c:\unlock was not in the OP. really needed to make any of these scripts work!
[Acer Iconia Tab A100] bertmansk:
i have rooted my A100 successfully by following these instructions:

Full root for A10x and A5xx ICS. Simple method.

i am now trying this unlock but i get stuck from the get go.

i open the install-eng.bat file. it will connect to the device, tell me daemon was started successfully, then nothing. it never moves past that.

i tried two computers and a different USB cable. i tried with and without USB debugging. i opened the bat file by both running CMD as administrator, CD'ing to the directory and open from there. i've also tried just opening the bat file by just clicking on it, with always the same outcome.

i saw a spanish video on youtube where he shows after running the bat file, the tablet almost immediately reboots. mine doesn't do this :eek:

i tried searching, it seems i'm the only one with this issue.

PS my A100 is updated to 4.0.3 ICS.
[Acer Iconia Tab A100] Theonew:
Leave USB debugging enabled. Make sure you have the drivers for your tab installed. That usually occurs when they're not.
[Acer Iconia Tab A100] bertmansk:
thanks a lot. installed the driver from acer's website (i'd provide the link but i don't have 10 posts yet), and it went through. perfect!
[Acer Iconia Tab A100] star_fire:
Hey OP, I own a Mac and I created a version packed with osx-compiled versions of adb and fastboot. Also aded the USB vendor so that Fastboot can detect the device properly.

To unlock the bootloader all you have to do on a mac is execute

sudo sh btl-a200_mac.sh

Alternatively to revert, execute from the terminal.

sudo sh blt-a100_mac.sh

and let the magic happen.

I have left the Windows and Linux binaries and scripts unchanged.

I have personally tested the package on my A100 and it works, anyway if someone finds a glitch PM-me.

Hi everyone, I am new to this forum and the a100. I have made a mistake and need some advice before I go any farther. I have flashed recovery and roms on 3 other devices so I got a little ahead of myself with this tabby. I have successfully rooted it. But, I flashed the CWM recovery using the "recovery IMG... easy as 1-2-3 jejeje" where you put it on the root of the sdcard and use terminal emulator to install. It I forgot i have to unlock gthe bootloader. So when I went into recovery I got the green android with spinning bucky ball(?) and it then it which to the android laying down withe the red triangle with the explanation point It was then when I realized I had messed up. Can I go a head and install the unlocker for the bootloader now or do I need to uninstall the recovery img first(which I do not know how to do)?
[Acer Iconia Tab A100] pio_masaki:
Go ahead and run the script to unlock then you rename /system/etc/install-recovery.sh to something else, I just change sh to bak, install recovery then you're good to go. If you don't rename that file it'll overwrite your recovery whenever android boots.

[Acer Iconia Tab A100] lartomar2002:
You said to install recovery after I change the name but I already installed recover, only it did not show up when I booted into recovery because I had not unlocked the bootloader. Are telling me I will have to reinstall CWM again?
[Acer Iconia Tab A100] Theonew:
Here's what you should do:

- unlock the bootloader

- boot into android and rename the file

- install the custom recovery
[Acer Iconia Tab A100] pio_masaki:
Yes I am saying that. I also said why you have to in the same post, it overwrites any recovery that's not acer's recovery every boot as long as that file is there and not moved or renamed.

[Acer Iconia Tab A100] Izzyb914:
After Step # 4 ( Reboot the Tablet ) can you Power Off with Power Down Button and Reboot would be to Power On Again with a Successful UNLOCKED Boot Loader, instead of using a Command to Reboot ? Also every time the Tablet Boots would it Show in the Upper Left Hand Corner that the Boot Loader is UNLOCKED ?
[Acer Iconia Tab A100] pio_masaki:
You can power down yes. And that's normal to show, supposed to be there.

I can not remember after which I did, unlocking the bl, rooting, or installing CWM. but, when I boot up the green ACERs logo a long the bottom appears a little distorted with a bunch of lines running horizontally through it and the white lettering along the top are the same and completely unreadable. Is this normal.

That's caused by unlocking the bootloader. Don't worry, it is normal.
