I dont know... kinda stumped on this now. Only other thing I can say to try is instead of flashing the boot img, see if it will just run.

(adb command)

fastboot boot BOOT_mmcblk0p2.img

or download the ICS leak update or the official one and try to install it through adb

(adb command)

fastboot update [path to update.zip]

and you tryed to unlock the bootloader again?

http://xdaforums.com/showthread.php?t=1557445

at any point are you getting the green android laying down? or it goes to the android logo and sits there?
[Acer Iconia Tab A100] luthifer:
It says Fastboot: Not support the command in Lock mode...

I tried that multiple times. This is what really has me confused. it says "error: failed to load update.zip". It is almost as if it is not reading the sdcard at all. I've tried different sdcards formatted as fat and fat32, still nothing.

It hangs at "wait for connecting device". I don't know how to get adb access since the tablet won't boot apart from fastboot mode.

If i run the update.zip using power & volume- i get the android logo with the blue spinning thing then there is the green android lying down with the red exclamation over its body. what's funny is that there is no progress bar at all and the same thing happens whether the sdcard is in or not. If i let it boot normally, it just sits at the acer logo forever.

EDIT* I just found out that the fastboot command "fastboot update update.zip" reads the zip file from the working folder, taht is the folder where you run your adb commands from. when i put an update.zip in this folder, instead of "failed to load update.zip" I got

archive does not contain 'android-info.txt'

archive does not contain 'android-product'.txt

error: update package has no android-info.txt or android-product.txt
[Acer Iconia Tab A100] TheBlackshinobi:
I kinda figured that would happen :/

I had the same problem. The first time I ran it, it hung after the reboot then wouldnt do anything and I got the same message.

Again, same problem I had.

Sorry, I should have been more clear about that step. yes, the path is to the working folder on the pc.

Seems like everything your are getting are the same issues I had. I know you tried it already, but I know it worked for me. Run the unlock command again. Im sure you know how to get it to fastboot mode, butI just want to list all of the steps that I did.

1) Install the USB drivers on your PC if you haven't done it already. ( http://global-download.acer.com/GDF...A TAB&Step3=A100&OS=a08&LC=en&BC=Acer&SC=PA_6 )

2) Have the tablet off, then plug it to the PC. Hold the vol DOWN button then hold the POWER button. Keep them both down until the unit vibrates.

3) Once it does, move the rotate lock switch back and forth until you see "Bootloader v0.03.06-ICS(LockMode): Starting Fastboot USB download protocol"

This should put you in fastboot mode.

4) run command prompt on PC (cmd.exe)

5) cd to the platorm-tools dir

6) type the following lines one at a time.

adb.exe

fastboot oem unlock

A lock should appear on screen, press it

7) type

fasboot reboot-bootloader

you should see that the bootloader is now unlocked

8) type

fastboot erase recovery

fastboot flash recovery [path to TWRP recovery img]

9) hold the vol down button on the tablet

10) type fastboot reboot.

HOPEFULLY all goes well and it boots to the new recovery. If it does, goto settings and mount the external SD card then goto install and flash the update.zip file.

If none of this works, im sorry, I have no clue what to do since this is exactly what I did to fix mine.
[Acer Iconia Tab A100] saleandoli@aol.com:
Thank you Blackshinobi, I have twrp now... I am just a little unclear on how to flash from the install screen and the update.zip is the ics leak that is renamed correct? Thank you so much for giving me hope .
[Acer Iconia Tab A100] saleandoli@aol.com:
Okay twrp gives me two errror codes

unknown volume for for path SDCARD:update.zip

can't mount SDCARD:update.zip

installation aborted
[Acer Iconia Tab A100] saleandoli@aol.com:
I flashed cwm recovery and tried to flash the update.zip and it says

Can't open /sdcard/update.zip(no such file or directory)

any helps please?
[Acer Iconia Tab A100] TheBlackshinobi:
yes, the leak should be named update.zip. place it on the root of your external SD card via your PC. Place that card back into the tablet and boot into recovery. When you get the grey TWRP recovery screen, goto settings and mount the external SD card, then go back to install and you should be able to browse the card and select the update.zip file. After that you should be able to boot the tablet finally and enjoy ICS!

Happy you were able to get this far!
[Acer Iconia Tab A100] saleandoli@aol.com:
I couldn't have done it without you and all the others who so kindly donated of thier time and skill, thank you all!

[Acer Iconia Tab A100] tmhtpcmbl:
Actually ... when you boot into recovery and you navigate to mount the external_sd card ... cwm allows you to choose it as the "internal sd" ... that may be what might have been confusing about what to choose when trying to mount the external_sd card
[Acer Iconia Tab A100] TheBlackshinobi:
if the leak wont flash, try the official ICS or one of the roms made by the members of the forum
[Acer Iconia Tab A100] Dave Clandestine:
Device hanging on boot

I wonder if anyone can help me too. I have a similar problem with a crashed A100 and all the solutions on this and other threads have not worked yet.

Symptoms:

On a normal boot, it sticks on the Android logo.

On holding power and left volume button, without an SD card, shows the usual android with and exclamation mark. When I then hit the home button a menu comes up titled "Android system recovery <3e>.

I can move the selection using the volume buttons but don't know how to activate any of them. (home button just hides/shows the menu screen).

I have loaded the Acer usb drivers, but device will not connect. (Tried using adb and fastboot options)

I have placed the stock rom listed in http://xdaforums.com/showthread.php?t=1611696 on a newly formatted SD Card (fat32), at root renamed to update.zip. looks like it works, reboots, says start updating ebt, finished updating ebt, Reboots again, and continues to hang on android logo again.

I don't know what else to do, or if my device is just toast.

Short Version: Tried a lot of options but device still does not work.

Edit: I finally managed to get my device into Fastboot Mode, so USB now works, but Bootloader seems locked. ADB still does not connect

I think I made it worse....I flashed twrp and thought I might as well try wiping sd and system since nothing else would work and then flash cwm...of course after the wipes and removing twrp I cannot flash anything else....man I am lame...anymore advice?:eek:
[Acer Iconia Tab A100] pio_masaki:
Why are you randomly flashing and wiping stuff? I mean really if you have issues you don't wipe and flash whatever you feel like and expect it to not get worse. You had a working recovery right? Now you can't get into recovery?

Why would you wipe then flash a recovery but NOT a system? It can't run without it.

If you still have recovery flash a damned rom or restore a backup before you do anything else. And stop wiping random stuff, fantastic way to make a $250 paperweight.

/rant

Now. What does the system do when you power on? Do you have fast boot adb or recovery? Since things are different you need to add specific information about it now.

[Acer Iconia Tab A100] saleandoli@aol.com:
Lol, nice rant...Okay I still have fastboot, but can't flash a recovery or an update.zip...Before I wiped I had tried for weeks to flash anything and all I could get was a recovery(cwm, and twrp). Nothing would load off of the ext sd either, I tried stock and custom rom's already and nothing would load in recovery...It has been over a month already, and I thought I had nothing to lose by wiping since all the forums have dead ended for me...Thank you for your interest in helping...Perhaps you have fresh insights?
[Acer Iconia Tab A100] SlavPala4a:
I am open to suggestions:

1. USB drivers Installed (Win7 does not recognize my tab)

2. Stuck at ACER UNlocked Mode after full wipe with the >Blackhole Nullifier & Wipe< and applying the official update.zip from my micro SD(extracted successfully)

3.Trying a Factory Reset reboots the device

4. I can't enter the recovery...I have no idea how

I am preparing for warranty and I need the device clean asap

PLEASE HELP!

[Acer Iconia Tab A100] saleandoli@aol.com:
Lol, there should be a thanks for nothing button also...don't rant on someones wall and not help...much thanks to all those that did try I think it's time to lay my a100 to rest.
[Acer Iconia Tab A100] pio_masaki:
Actually I was trying to help I asked some questions and never noticed he replied back with the answers until now. I'm rather busy with other stuff sorry I didn't catch it until now.

And since its obvious my help wouldn't be appreciated anyways, sorry you called it dead. I'll spend my time elsewhere.

Edit: I was a little short on time for that post, so let me finish what I was trying to say. The thanks for nothing comment isn't really valid, the rant did have one very important point you all seemed to have missed, and hopefully the next person who has this issue will see it. I'm sorry you didn't think I was offering help in a way you understand, however being called out on making mistakes is helpful to other people in the same situation. Learn from others' mistakes.

That being said, I'm pretty sure I developed a method to repair this somewhat common issue of bricking, CWM/TWRP works, but nothing else does. I've been reading yours and others' posts and threads about this, and I think I figured it out. I tested it on mine, and mine works. Just fine. It was to be my final project and contribution to the A100 forums, however I needed someone else with a semi bricked device to test it, to make sure it wasn't a fluke. Yes, I've bricked my device a few times in different ways. I do it while trying to make ROMs and other tools for everyone to use to make their life easier. Is it appreciated that I offer help and methods to aid in A100 usage? Seems not.

My final project is on hold until I find someone else who is willing to let me test this method on their device, and is willing to understand I don't have alot of time to do things, look at my Sig, I did all of that. I maintain all of that, I update all of that, plus working on the CyanogenMod Wiki, I'm busy trying to create useful things for multiple devices. You have what, 2 Thanks? Maybe you should calm down with your witty remarks and keep in mind people help WHEN and HOW they can. Maybe someday someone else can figure out how to unbrick these and you can restore your tablet back to operation, maybe not.

This isn't aimed entirely at any one post, thread or user, I've had people complain and whine and call me nasty things in PMs as well, and this last post just kinda did it for me. I'll attempt to perfect the method so you and others' tablet can be restored. It may work, it may not. That's about as helpful as I can get.

[Acer Iconia Tab A100] pio_masaki:
Ok as I mentioned before I think I had a method to repair a bricked a100, from what I can see, you have fastboot and you can go into recovery, CWM and/or TWRP. Does this mean fast boot can flash your recovery from your PC, or is that no longer working? If it does work, if you flash TWRP, can you go into mounts and tap the circle next to external, and then backup or restore from external sd? Or attempt installing a rom from there? I mean a custom ROM, not update.zip. If you can run a zip but it fails, please let me know how it fails and what it says. Also, hopefully adb and external sd works, the method I've come up with fails over PC, but works from external SD in TWRP with commands in ADB Shell, which I suppose I could create a flashable script to do, but again it NEEDS to have TWRP or CWM working, and access to external SD card.

If it won't use external SD card, but ADB works, I'll need the recovery log:

adb pull /cache/recovery/last_log > /recovery.txt

This should copy the file to whatever directory your ADB is run from. That will show why whatever partition isn't mounting, likely due to some kind of filesystem corruption or bad super block. I've recovered from these over ADB, and I've noticed if the /cache partition is wrecked then the normal update.zip method fails.

So, please be clear in what works and does not work, and I'll attempt to create a script to repair the /cache partition and /system partition. Downside, it will be HUGE. the system.img is 1.2GB by itself. However this method will completely overwrite, from the first byte to the last, with a mirror image of MY working system partition. Cache, if wrecked, will have the same thing done. I won't do /data since it contains the internal SD it'll be over 5GB, but a working /cache and /system should get you going again. Its basically my nullifier, but backwords, it puts data on the partition instead of zeroing it out.

If the script can't work because external sd won't mount, I'm not real sure how to fix it by launching the scripts or files from PC instead, I'll have to figure that one out if we know for sure external SD isn't working. I mean I can do it here on my machine with my device, but you're there with your machine and device, which doesn't help much, I doubt you feel like mailing it out to some random guy on XDA.
[Acer Iconia Tab A100] saleandoli@aol.com:
Lol, my apolagies and thanks button then are yours...I am not used to people ranting on my posts and seemingly leaving. I saw your thanks meter so your abilities were not in question . Lol and the two I do have were not sought after, I do not profess to know enough to be of any help, but if you can help any of the others who have posted on my thread please do I'm sure they can benefit greatly from your knowledge . Thank you again.
[Acer Iconia Tab A100] pio_masaki:
The thanks given freely are the ones earned, I'm not one to beg for thanks, and I hate seeing signatures asking for them (maybe reminding is a better word?). I understand why you would be annoyed by my post and then pretty much just never helping, it wasn't my most helpful post to begin with.

I'm still slowly working on a method to get a bricked tablet back up, however I hit a wall that I can't pass, as I mentioned in another brick thread, I can't go much farther until I get ahold of a bricked A100, mine doesn't show this symptom regardless of how I wreck the partitions and brick it, it always comes back with minor adb usage.

The SBK failing seems to be an issue with the bootloader blob we used to unlock the bootloader for installing custom recoveries, and on top of that, the A100 may use a different key (likely) then the A500, and until it gets released, leaked, or Acer offers an unlock token like HTC does, then there may not be much we can do with APX mode, or NVFlash. That leaves at most fastboot, and hopefully ADB, which I know can be used to come back from a non booting tablet (done it way to many times to my own testing all this stuff out). If we have fastboot, then fastboot flash boot boot.img and variants of that for system, cache and recovery can be used to replace the current partition images with a working one, I have pulled them from my own system however they are FULL partition images, meaning over 1GB for system. This is one of the reasons I need a bricked tablet for my testing, not sure many people are willing to try such a long tedious process.

The other option is if we have ADB, then we can use DD to write the image to the partition sector by sector, byte by byte, to create a true mirror image clone of my system, cache, recovery, boot images. These may both fail to work if the EMMC is truly damaged in some way, bad sectors, anything really, can stop DD from working. That leaves NVFlash to repartition around it, but we are locked out and can't use this option. So, a few road blocks before I can begin testing what can and can't work.

I'm still looking for a bricked A100 to get ahold of locally, however none are available (or at least posted for sale). I have $9 in my donation fund, if someone is willing to ship their tablet to me, I'll transfer that over for shipping if it helps. I know, random guy on xda begg0rz device flag, but like I said, I'm trying to create a method that will help at some point, ALOT of A100 device owners that face this same problem. I may make a post in General requesting a loan of a bricked tablet for testing, but I'm not sure about the rules concerning this. If someone happens across this and is interested, shoot me a PM.

Please How can you get into fastboot? I have this same problem but i can't get into fastboot... :(
[Acer Iconia Tab A100] das_webos_transformer:
Fast boot requires the android sdk and some basic knowledge of the command line ex cd'ing to where your platform tools are. If you get that far, hopefully you do, the commands for me are like

CD c:\program files(x86)\android\android-sdk\platform-tools\

Then when you get to platform tools

Adb reboot[recovery

It would look a lot like that. Not as hard as it looks, but you will need the android sdk installed.

[Acer Iconia Tab A100] Mazzstrikers:
Ok I bricked my A500 before and got it back working. Same situation, can't access fastboot, can't use ADB and can't get into recovery. Now I'm gonna help you. Check if your A100 has a reset button like my A500. The type that you can insert a paperclip in to press. My A500 has a failsafe mode by doing a combo press on the reset.
[Acer Iconia Tab A100] lorrisek:
I have Android SDK but my PC doesn't recognize my tab and when i connected my A100 to PC its going reboot and reboot.
[Acer Iconia Tab A100] Mazzstrikers:
Yup people I experienced the exact same thing on my A500 before. The only way out is through APX mode (a failsafe mode built into the tablet). You will need to obtain your cpuid, which you can google how to do it using a USB software, which can dig up a list of ids of all the devices you have connected to your pc before. With this cpuid you can exchange for a SBK code. This SBK code, when entered into a package provided by acer (which you can google and download), will flash everything back to stock ROM, stock kernel etc.

All the info is on this link, it's for A500 but read through it first, very helpful.

[Acer Iconia Tab A100] pio_masaki:
Yes it does and we do have apx mode and we can use it, but without our sbk we can't make any use of it, which was my point.

Although I suppose I stopped my research to soon, I'll have to go find who originally figured out the a500 sbk (vache?) and see if we can apply that to the a100. This would then only work on a100 bootloaders not the a200 bootloader we use to unlock. I'm planning to get an a200 as well so maybe it can be applied to that as well, however the cpuid reported by the a200 bootloader seems to be incorrect.

That by itself would cause issues even with the correct sbk as the tegra would deny the correct boot loader sbk and the boot loader will reject the correct hardware sbk.

Guess its time to revert back to stock and start attacking it.

[Acer Iconia Tab A100] Mazzstrikers:
For A500 Vache found a method to obtain SBK from cpuid. There must be a way, maybe you want to contact him? Cause with SBK many bricked devices can be recovered. Also try Vache's website using an A100 cpuid to see if it works. Do let me know if it does.
[Acer Iconia Tab A100] pio_masaki:
It doesn't I've tried it before, but maybe someone with a stock a100 and boot loader can try and see.

I'm a bit busy so I haven't reached out to vache on this, as it is my a100 must remain modded and fully operational, both for my own purposes and building and for waydownsouth as I promised I wouldn't mess with it until its no longer needed for his testing.

Anyone else can of course feel free to work on this while I'm sidetracked and somewhat unable to mess with this at this time, I'm sure the a100 community would appreciate it.

So, ok is there any way how can i unbrick my tab? Is there existing program which flashed the stock Android like PC Companion?
[Acer Iconia Tab A100] Mazzstrikers:
Shouldn't the cpuid be the same whether stock or modded, unlocked or not? Hence SBK should be the same.

I don't have an A500, but I'm sure you guys in this thread are eager to unbrick your A100. Try going to the link in my previous post. It's for the A500 but no harm trying. There's nothing to lose when you've got a paperweight in your hands.
[Acer Iconia Tab A100] Mazzstrikers:
The cpuid should be the same regardless of stock or modded, locked or unlocked bootloader. It is like the fingerprint of your device, like the IMEI number of your phone. The SBK is only a derivative of the cpuid, hence Vache probably found the method to derive SBK from cpuid. I doubt A100 will be any different since SBK codes are from Acer.

Guys in this thread, I don't have an A100 here so I need you guys to go to my link in the previous post to try the APX method. There's nothing to lose when you are facing a paperweight in your hands.
[Acer Iconia Tab A100] lorrisek:
I can connect my A100 only like APX device. Is there something what i can do from there?
