[Q] Need direction with a frozen A500

I've got an Acer A500 that's frozen on the Acer logo on restart. I can't get into recovery. I can't hard reset. When I press the power button (+/-) volume button, it vibrates and freezes on the logo... every time.
This happened after trying to root and install Thor's ROM.
I know there's other threads on this, but I can't find one to help me when I can't get into recovery.
Sorry, I'm sort of new at this...

fixed
Nevermind... reverted back to stock with EUU in APX.

How did you revert to stock? Mine: A500 not rooted stuck on google sign in screen.
unresponsive even after sticking a paperclip in it. not even certain if I did the "stick" correctly. Any simple direction? Just watched youtube flashing for a gtablet. same android but mine is acer Iconia a500. do have two google accounts linked to this tablet just can't get online with it. had gotten online with Samsung precedent and pdanet but lost 3g on phone so got cable internet (no router). can I route from asus k501j? not sure how to. did download some acer files from acer, have them unblocked and unzipped. haven't combined into one folder yet. not sure if that is correct procedure. files are: usb acer 1.00.0524, application acer 1.06.3006 and patch acer 1.0 A31. thanks, on verge of giving up.

[Q] A500 Boot Issues...need assistance

I've searched and found a few similar (not identical) problems that people were having, and tried some of the solutions, and none have worked.
I'm trying to fix this stock Acer A500 for a friend. It will boot up part way, goes past the acer screen and android screen, but then stops at a black screen with 'android system' in the upper left corner, the home and back buttons in the bottom left, and the time, signal, and battery life logos in the bottom right. Then there's the Power Off thing in the center of the screen, and it says shutting down but it never shuts down.
I boot into the stock recovery mode, and it says in the upper left on the acer screen:
erasing cache before SD update
SD update cmd: recovery
--update_package=sdcard:update.zip
booting recovery kernel image
then it shows the android with the turning gears, then goes straight to the android with the warning symbol.
Since I can't get into the OS, i have no idea which version or specific model this is, but i downloaded a few different honeycomb update.zips, and put those on the SD card, and when i tried booting with those, the loading bar pops up under the android logo, and it goes to about 1/3 of completion before switching back to the warning symbol.
I tried downloading what im pretty sure was a full version of jellybean for this tablet, and it went straight to the warning symbol, no loading bar. same when i tried renaming the file update.zip >.>
im clearly very new to all this, but i'd really like to get this thing working.
is there a way to do a factory reset without booting all the way into the OS?
im not sure because it seems like the only file its looking for in recovery mode is update.zip.
if anyone has any bright ideas, id appreciate the help.
Also, not sure if this is relevant, but when i boot it normally, and it goes to the 'shutting down' screen, the battery level indicator says its almost dead, but i can leave it plugged in for hours and nothing changes at all.
EDIT: Also, it won't even boot if the power cable is not connected.

Similar issue hope there is a solution
I have a similar problem. Tablet was working fine, sitting on docking station. Returned to it the next day and when I went to wake it, it would not wake. Rebooted it but will not reboot. Sits on the ANDROID screen after the ASUS title screen indefinitely. If I try and boot into recovery it fails at "update.zip" and I see the broken Android image laying there.
Is there a means to restore it from PC via the usb cable and can someone please post a very noob friendly walk through step-by-step?
Greatly appreciate any positive advice!

Probably the mmc failed. Same symptoms as mine. Non-recoverable.

Yep.. 14 months old in my case. Contacted Acer and said "what about a fix?" They said, "no chance unless you cross our palms with lots of silver."
So, bought a Samsung Note 10.1 instead. Acer can "stuff it". I won't be buying a tablet from them again. Considering that I bought their "flagship" product of the A501 with the 64GB memory, this is truly unacceptable.
I was incredibly careful with it and certainly never did anything to void the warranty. But, you only get 12 months and then it's over.

I wouldn't go as far as to say dead, have you tried booting into APX mode and then running BABsector?

Definitely more than I can manage but I've handed the tablet over to a friend who is capable of understanding and performing your suggestions. All are greatly appreciated.
Thanks!

Hey Skurtov,
Thanks for the offer to help my friend NoOneSpecific.
If my Android terminology is correct, APX mode is the diagnostic mode which invokes the Bootloader when a device specific combination is held while powering on, right? And while the Bootloader GUI is active, it is shown on a PC as an Nvidia device?
I believe the key combination on the A500 is Volume-Down and Power, but doing this causes the tablet to automatically boot from the recovery kernel image. The same message appears regardless of whether an SD card with a decrypted update.zip is present or not.
If I am mistaken, I would greatly appreciate your help in pointing me to the right step in getting my friend's tablet working again!
Cheers!

You are quite right sir, however the button combination I am most familiar with is holding the power and the reset button (the one you have to stick the paper clip in) when you first start it up. It should then either say APX mode on the screen or be blank, either way the computer will identify it as a APX device and automatically install the drivers.
Going into APX MODE manualy
You enter APX mode by holding down the Reset button(with paper clip). Do not release it. Hold down power for 3 secs and then release it. After another second, release the reset button.
Your Windows PC should then detect your device and install the APX driver. You should then have an APX USB device installed. If you do not have an APX USB device listed in your system tray, you cannot proceed.
The screen of your tablet is black.

The next course of action is to get the SBK, from what it sounds like the tablet didn't write a partition properly and that's why it's not booting. So what you can do is wipe out the partitions and install a custom bootloader and recovery. Not only does it fix things but it also opens up his world to custom roms . Okay, back to the matter at hand, I don't know if he has his SBK or not, and if he does skip the step to find it and just run babsector below. If not then follow the next step.
You'll have to pull the UID from the tablet using this method described here:
http://git.pappkartong.se/?p=a500/apxuid.git;a=snapshot;h=HEAD;sf=tgz
There's a readme
After getting the UID and calculating your SBK you'll just go to the next step.

Run this file hosted here:
http://narod.ru/disk/53919831001.a235ea2225f319015f30c009629d2075/BabSector.rar.html
And this file basically rewrites and formats the partitions out installs a custom bootloader and recovery

Once this is done, pick a new rom. I prefer the Civato ones, load it on a SD, boot to recovery, erase dalvik cache, cache, do a factory reset wipe (from the recovery menu!), then wipe system, flash the rom and go on your merry way

Many thanks for the reply.
As per your instructions, I have booted the tablet into APX mode. However, as I do not know the UID of the device, I've had to try to run the utilities to create a driver for the device and then pull UID from the tablet...
I am able to create the driver for the device and install it with driver signing off in Windows, but I can't figure out how to run the script to get the UID. I notice the file in the package you directed me to contains an .SLN file, which would indicate it is a programming solution file. I have Visual Studio on my system but it cannot open this particular .SLN file.
How would I run what's in the package to pull out the UID of the tablet?
Any help getting past this hurdle would be much appreciated!

ACER A500 Iconia Tablet -- Stuck at Acer Logo...

Was using tablet and just playing a game -- tablet reset, robot with ! showed up.
After that, reboots bring me only to the Acer screen.
I can do the VOLUME UP + POWER -- vibrates, powers up, toggle the switch, let go of power button and it does:
ERASING USERDATA...
ERASING CACHE...
Then it reboots back to the ACER logo, and just sits there. I have downloaded one of the ROMs and done the VOLUME with POWER BUTTON start up and it doesn't do anything. Just stays at ACER logo.
I've looked at quite a few things here on the forums and it hasn't done me any good -- nothing seems to want to work with the tablet unless it's in debug mode (which means it has to be a working tab). When connected to a PC it does detect as an MTP USB DEVICE and says "THIS DEVICE IS WORKING PROPERLY." But I can't get much of anything. The only thing I've used that remotely works is USBDEVIEW which gives me the device info including a serial #, which I understand is NOT the cpuid. I do have the box, so I guess that would have the CPUID? Any help appreciate. More than willing to just blast this thing with a one touch factory reset from the PC, if it will just connect.

If you had it at the dead android guy, it means you probably didn't have the decrypted "update.zip" on your Ext SD card. If you had stock ICS running before, you can try downloading those 4 update.zips I posted a few threads ago. Will have to try each one, and hopefully one of them works.

It went to the Dead Android guy when it rebooted after a crash. I haven't seen it since. Just got to the Acer logo screen and stops.
Your linked post is going to what it actually shows instead of the real link.

I'm also stuck at the ACER logo. I d/l'd all four of the zips from your link. All four appear to install correctly but when the flash finishes and the tablet reboots, it's still stuck at the logo.
Also, when I just tried the link again, it is no longer working.

where were you coming from when you tried this ? what BL? gb?JB? what recovery , theres a alot of reading to be done with this device Acer didnt make it easy , but if you read and take it slow there are/were some great devs that left the door open for us all to use these ? Explain where your started from and how you got to where you are now? (Moscow is a sharp dude he can help)!

I bought the tablet used and it would loop on the green "ANDROID" screen. So I don't know what version it was on. I tried the volume +, rotation left and power on to clear the cache and user data. After that it hangs at the ACER screen. I'm assuming it had HC because it has standard recovery. IOW, if I hold the volume - when powering on, it goes to the green Android logo and if an "update.zip" file is present, it will flash it. I've tried just about every "full" ROM I can find and most of them flash but none of them get past "ACER".
I've tried pushing the reset button while powering on while connected to both a Linux box running Mint 15 and a Win7 box. The Win7 box see the tab but won't load the driver. Even though I d/l'd the USB driver from the Acer site. Mint 15 sees the tab but comes up with the error box saying it can't be mounted.

[Q] Bricked A500 tried everything, I think!

Ok I have a stock acer a500, one day it went to shutdown, I turned it on and guess what? hung at the ACER screen, I finally got my CPUID & SBK (thank you linux, love that ****) well I tried the apx flash tool with every bundle it would let me download, they all finish but it always hangs at the acer screen! Ive tried barbsector and got an error which i will post later if the tdv4 tool doesnt work which im running right now! i have previously put two mainboards into this thing and this is the thanks i get! well anyways I need some help here!

Does your screen just have the acer logo or do you see some white text in the top left corner?

[Q] Acer a500 wont boot

hello, I recieved an acer a500 from a friend, because he couldnt make it boot.
I looked around these forums, looking for an answer but nothing seems to work.
First of all, this is an european acer A500 tablet,
when I power it up, it comes the ACER logo, with a red writing in the left corner > Boot verified failed
so I tried all the factory resets possible combos, power and volume up, but nothing works.
I downloaded from this site various update.zip files, put them one by one in the SD, and tried loading them with the power and volume button, but what happens is, first it comes the ANDROID logo loading, then on the ANDROID logo comes a RED triangle, and nothing happens.
I dont know what O.S was installed here.
I also managed to get to another screen while pressing the reset buttons,
thats a black screen, with this writing in the corner > Bootloader v0.03.12-ICS: Starting Fastboot USB download protocol
That-s all I managed to do, but nothing works for me, so could someone point me out a working update.zip file, or something, to unbrick this A500 please

if needed, i managed to get the UID code with ubuntu, and the SBK key
i-m still trying all the update.zip i can find on these forums, and so far, only one managed to get me a loading bar under the Green Robot, instead of giving the RED TRIANGLE error, but after 1hour, the loading bar is stuck on like 25%
help me pls

Either babsector.rar file and flash a custom ics rom. Or the tdv4 file, which will flash an HC Rom for you.
You will need a pc, the drivers and cpuid, instructions and downloads in the root guide in my sig
