Hi there,
I have an A501 and recently updated from 3.01 (rooted) to 3.2. Now, I want to go back to 3.1 in order to root it again and then to one of the custom roms with 3.2.
So, I decrypted the update file by Acer and put the update.zip on my sd card in the root. I then restarted the tab pressing Volume and Power. It switches on and on the upper left side it says: "Booting recovery kernel image" - and that's it. For over an hour, nothing has been happening. I resetted it once and repeated the procedure, but it again stuck on that message.
Do you have any idea what could be wrong?
I think you are not holding the buttons long enough.you should hold them until you see the 4th line of text.at that point recovery should start.if you are on stock recovery you could have a currupt update.zip or incompatible SD card.
Hi,
yesterday I tried it several times and one time suddenly a green android appeared with an exclamation mark. What does that mean?
I use the sd card I used in my Galaxy S2 and there it worked with images. How can I check if my update.zip is corrupted? I can open it without problem on my pc.
Hi,
I have the same problem ! The droid with an exclamation mark. Any solution ?
Thank you !
I think the stock recovery is looking for an update.zip file on the sdcard. It either does not find this file or the file is not correct.
After an OTA update on my 2 day old tablet it gets stuck on the splash screen. Everything was stock. Update looked like it installed correctly and everything. I tried flashing the stock package provided on this website but in the top left corner in red letters it says "recovery verified failed"
I extracted the files. put the update.zip in the root of my sd card.
I don't know what version my tablet had on it as i didnt even have it long enough to play with it.
Any ideas before I have to send it back and wait for weeks on a replacement?
Itncould be a defective tablet.
You could try a reset with the reset hole on side next to USB port.might revert it back. Or d/load a full rom put on formatted SD cardnand try to flash holding volume down and power until flash starts
Lots more info about this in dev area.
Goodluck.
I tried the reset button but its still stuck on the screen when it reboots. I tried that flash method with a full Rom and that's when I got the red error message.
Thanks for the quick reply.

My a500 gets stuck
Hello. I have an Acer Iconia Tab A200, and recently I tried a factory reset. However, due to my meddling with system files, it won't reset.
I've tried to do a hard reset (Power on, Volume+, Orientation lock switch) but it says the following:
Erasing Userdata...
Erasing Cache...
It then reboots, and does nothing. It hangs on the Acer logo.
When trying to go into recovery (Power On, Volume-), it says the following:
Erasing Cache before SD update...
SD update cmd: recovery
--update_package=SDCARD:update.zip
Booting recovery kernel image
Recovery verified fail ...
Now, I mentioned that I meddled with the System Files. Here is what I did:
1. Removed unwanted Vendor Apps
2. Removed the DEFAULT LAUNCHER <-- I think this plays a big part in this
3. Placed a CUSTOM LAUNCHER in the VENDOR APPS FILE
4. Did a FACTORY RESET
My brother is more techy than me, so he tried to fix it. However, he somehow re-locked the bootloader and even replaced the bootloader with a newer version.
I talked to Acer Support claiming it's system files corrupted itself, but they won't fix it unless I also pay to fix my cracked screen. I'm willing to do so, but hey, I'd like to see if I could save $120. I don't mind the cracked screen.
NOTES:
The Acer Iconia Tab A200, along with their other tablets, has a USB port. I can probably load stuff from there somehow, but not sure.
It is a 16GB model with a 32GB Class 10 MicroSD card in it.
Any ideas? All help is appreciated.

Do you have access to any a200 Update roms? Sometimes, you can pull the update.zip from the rom, place it on your ext sd card, reboot holding Vol+ and PWR, and it might install.

I have searched for some A200 ROMs, but can't find any that work using that method. I'm open for ANY Acer A200 official ROM, then simply updating using OTA. I tried an Acer A200 Recovery Pack I found. It is the exact stock Honeycomb image, but it didn't go. It always says recovery verified fail. I cannot unlock the BootLoader either.
Stockimage flashable while having bricked /DATA Partition
Hi Vuciz,
do you still have the issue with your bricked A200 ?
I got the same problem with mine, the only solution was to send it to repair, it seems the storage controller chip has some bug which destroyed the /DATA partition unrecoverable.
if you need to revert your Tablet to an locked bootloader you have to download an StockRom and modify it by removing the partition check (called "assert") in the update script.
please send me an message if you need further assistance.
regards and good luck with your tab.

Yes I do. However the screen is also cracked so they want me to pay for that. Which I'm unable to do at this time.
anything I do, fails

I also have this tablet. I bought it for 20 bucks because the screen was cracked. replaced the screen and then found out that the bootloader was trashed. I've done almost everything I can think of to fix it. Used APX mode to get UID from ubuntu, tried to use that UID to get sbk, got the SBK and then tried using blackthunder's tool got connection failure, tried using babsector same thing, even went in ubuntu, with tablet in manual apx mode for all three and when I attempt to reflash the bootloader, all I get is that command failure message with a nvflash connection failed nv error 0x30011 message and when that happens in windows, the tablet disappears from device manager, and in ubuntu when I run nvflash with the sbk function --sbk XXXX and so on, I get the command sent failure message, and then when i rerun lsusb, the nvidia device that represents my tablet in apx mode that showed before is no longer listed unless i reboot the tablet in apx mode again. If i boot it normally, the acer logo appears and then goes to the little animation and then the iconia tab screen and thats it. I've tried attempting to flash the bootloader from that screen which i know probably wasn't going to work anyways. If anyone has any advice on something I've missed, or anything that could help, i'll all eyes. thanks in advance.

I've been looking at threads and blogs all over to try and find a fix that will work but I can't find one. I guess this is sort of my last hope.
I tried to update CM7 using ROM Manager. I selected to flash the ROM and create a backup, but when it turned back on it got stuck in a boot loop at the "Touch the Future of Reading" screen. I then tried to create a bootable clockwork recovery SD card, but it just will not work. I re-burned the image to the SD card 3 times so far. All the Nook does is display the "Touch the Future of Reading" screen indefinitely. It no longer is in a boot loop, it just won't get past this screen.
I'm completely out of ideas, if somebody could tell me what to do to make it boot into clockwork recovery I would be really grateful. Really, getting it to boot into anything would be great.

You are in a recovery bootloop with no recovery installed. Go to my tips thread linked in my signature and make a bootable CWM SD as described in my item A10. It has been modified to get you out of these kinds of bootloops. Then you can flash whatever new recovery or ROM (including stock) you want. But do it manually with CWM, not ROM Manager.
EDIT: From the symptoms, it sounds like you had stock on emmc and CM7 on SD (Touch the Future... is stock). If that was the case, your mistake was using ROM Manager with the SD install. It does not work. It only works with emmc installs of CM.
WinDiskImager always tell me "an error has occured when attempting to get a handle on the device. Error 8." so I always use the dd command on Ubuntu to burn the image. Still, I tried to make a bootable SD out of that and my Nook still won't get passed the "Touch the Future of Reading" screen. Also, whenever I try and open the file on the card with the burned image, it tells me the filesystem type is unknown and that I have to format the card to use it.

It is not burned properly if windows cannot read it. Did you use an external card reader rather than any built into your PC? You should. That error message in win32diskimager tells me your hardware is not working. You need to keep trying until it is burned right or it will never boot.

A coworker has given me an a500 to try and restore to a working conditiion. Here is the story I was given... Tablet was working fine but he had a pop up informing of an update. He ignored it for awhile but finally let it update and after it rebooted he was presented with a password screen. He has no clue what the password is. I don't know what the tablet was updated to and to my knowledge it is not rooted.
I have tried erasing user data by holding down volume up and power and toggling the screen lock switch back and fourth after the tablet vibrates. Tablet displays
Erasing Cache before SD update.
SD update cmd:recovery
--update_package=sdcard:update.zip.
Then displays in red Secure boot: image sos checksum fail. I have had a couple different update.zip files on the sdcard when trying this but none are successful and it never seems to erase user data as it always asks for a password.
I have also tried an EUU update and putting the tablet into apx mode manually but this to fails. I was able to get the CPUID off of the device using a thread on this forum and an Ubuntu installation.
I have poured over numberous threads and tried many things over the last couple days and have had no luck. I am look for some help in either just erasing user data so we can go through set up again or downgrading/rooting or what ever it takes to get the tablet in a usable state again. I have a little knowledge of rooting and using adb and have never tried ubuntu until this weekend.
Thanks
Can someone help me with this? Any suggestions?

theres a thread titled "will pay to get my tab fixed" actually there are 2, but in one of them I think the problem was resolved....I'll post a link to it if i can find it
oh... u say u used an update.zip - make sure it isnt still on yr sdcard???
out of interest what happens when u press power + vol UP - just wondering what bootloader the tab has...doing this will tell us
what part of apx mode failed???
i guess you've seen the SOS/LNX checksum thread???
you have a serious failure here, but hopefully not irrecoverable....fingers crossed
Hi, Thanks for responding. Its taken me a while to get back to this because of Thanksgiving and a project at work.
The update.zip is on the sd card. How do I move it the tablet?
When I press power + vol up the tablet vibrates then displays acer on the center of the screen. It then displays in the corner of the screen:
Erasing Cache before SD Update...
SD update cmd:recovery
--update_package=SDCARD:update.zip
Secure boot: image SOS checksum fail!
With the EUU update I run the PBJ20upgrade.exe. I then let it time out and manually put the tablet in apx mode. I then put in my CPUID and hit next. The tablet vibrates and displaces entering Acer download mode but the PBJ20upgrade.exe program displays that the upgrade process failed as soon as it vibrates.
The EUU update i tried was titled EUUs_SBK_Acer_A501_0.017.01_PA_ATT
Thanks again for the help
