[GUIDE] How to unbrick Acer Iconia A500

I just got from a friend an Acer Iconia a500 he says that is bricked.
I tried this method: http://forum.xda-developers.com/showthread.php?t=1572622
But I can't continue because I don't have ADB access, what should I do?.
Thanks for all and God bless you.
EDIT:
I got everything to using the secret APX mode, but now is still everything the same the Android System is still there and not charging and not touchscreen...
Go to the bottom to see how I solved this lol...

If your tablet Iconia 500 (ONLY ACER ICONIA A500) went crazy, and present the next symptoms (Yes it has flu...):
-flu
-Android System icon
-Doesn't want to charge (20% / 15% 12%).
-TouchScreen is not responsive.
-Always when you turn it on says Shutting down and never shuts down.
-In case you're using ICS shuts down immediately without even make you see.​
The solution is the next!:
1. Download this file: http://www.4shared.com/archive/zyP91E0C/root-321-V4.html (This is the file to put recovery in case that you don't have it).
2. Extract all the files in any folder, it doesn't matter where you put it.
3. Go to Image Folder and rename the recovery to: anyname.img.
4. Download any of the lastest recoveries for Acer Iconia a500 (it will work believe me lol).
5. Put the recovery in the Image folder (Ex. Iconia/root-3.2.1/Image/) and rename it to recovery.img
6. Now open with Administrator Rights DotNetDetecter.exe
7. Continue, continue and continue.
8. If you have ADB Active just put it and it will install it. (If you don't have it just go to 8.1)
8.1 Shut down the tablet completly, connect your USB Cable *micro* (Tablet-Computer), take a paper clip and put it on reset without release it then press the power button and count until 4 or u4ntil you hear the sound when you plug something into Windows
8.2 Now your tablet is in APX Mode and the Acer Utility should now work.
9. Put your UID with a 0 in front of all the numbers (if you don't have it go to secret step).
10. Now let everything work. After everything is done you should have recovery now.
11. Press down volume and the tablet will take you to the recovery.
12. Download some ROM 3.2 or ICS 4.0.3, install it via recovery.
13. Download this file: http://www.mediafire.com/?9svnvdk982sxrw4
14. Install the version you have choosen via Recovery.
15. Voila! Your tablet is revived right now
Press thanks button if this helped you =D
SECRET STEP TO GET UID (IS NOT SECRET THOUGH... lol)
Just go to USB tools and use USBdeview, and is done... (Remember to stay in APX Mode)

Acer Recovery from the Market should have the most recent RA Recovery, and the original GPL compliant CWM recovery.
Or if you already have the original CWM, you can get the most recent RA Recovery here. Just check the threads for the flash files.

For CWM you will need to go to tegraowners.

Problems with opening up settings to turn on usb debugging
Hi Travisantonio,
I have a question:
Did you have any problems opening up the settings when you were on the black "android system" screen?
My touch screen is completely unresponsive at the moment.

Maybe I didnt read or understand everything but with my tab USB view didnt give me my ID or it wouldnt work. Got into ADX mode but couldnt get things working. Tried ADB to list devices and would never list anything. I heard my computer beep when I would hook it up but couldnt really do or complete anything. I couldnt get the DOTNETDETECTOR (PBJUPRADE_ to work. Tried A500 APX flash utitlity. Tired nvflash and falied. Guess I should list more information but at this point I tried so many things to recover dont remember the order I did things. I originally tried to upgrade to a Rom but all things failed and actually not sure what ever got completed. Only thing I could tell my tab did besides black screen was the power button either was white(some type of one) or orange.

This helped me to recover my bricked Acer 500 tablet after a failed ICS upgrade. The Acer update seemed to go okay, but on reboot it froze at the Acer logo and had an error in the corner. Every reboot or button/reset resulted in this. It would not recover or do anything else. I was able to get the USB device ID /serial number using the USB deview 64 program in the usb folder. There were several entries for the tablet but only one had a usable number (bottom right line at the end). Then the tool wiped the tablet and reloaded 3.2.1 and booted to factory new. Thanks for the instructions and to all the other XDA-ers for the tools. I am now on ICS properly.

Trying to recover a bricked acer a500, I just have a black screen on boot with no boot logo, vibration or letters or words on the screen
trying to enter recovery/update mode doesnt work
Im up to the step where is says put in your UID into the program
Just go to USB tools and use USBdeview, and is done...

I did this and found the device but where exactly is the UID located?
looking at other threads, the serial number is the UID however the serial number entry is blank for this device

this method is total overkill for your situation....
how did u get yr tab like this???
if u have total black screen - is the power button lite on?????
what bootloader version are u on
have you had a custom recovery on there
to get your cpuid follow the first link to a guide in my signature - you need to follow steps in the guide if you have any probs then post in the guide thread

the previous owner said he tried to install a custom rom and I think it crashed and this is the result
the power light turns on (white)
if I just power it on, the backlight turns on however its just a black screen, nothing else happens
apx mode seems to be the only thing working right now, I thought this method would be my only chance to get the recovery mode working again
I dont know anything else about the tablet, bootloader ect...

ok thats cool, apx mode works!!!
well try this first - using hard reset:
1) Turn off your tablet,
2) Rotation lock on your left;
3) Press Vol Up closest to rotation lock and power on simultaneously
4) As soon as the tablet vibrates you can release the power button and you should start to switch rotation lock left and right till you see

Erasing Cache...
Vol Up is still pressed;
5) The tablet starts to format
6) Your tablet will be as clean as it can be.
otherwise plan B!!!
do u know whether tab was running HC or ICS?
u need some package files and a flash tool either apxflash or nvflash
if u start the tools and then connect your tab via usb cable to your pc
there are links to guides in my sig
my cpuid guide shows u what u need and where to get it, info about your cpuid too and drivers - altho you wont need to worry too much seeing as youre in apx
civatos guide has all the links to the packages and all the info you need to patch the bootloader, then you can flash one of the ics roms and youre all good!!!
the process is simple enough - but if you get it wrong it can be frustrating as heck!!!!

tried that method, get no vibration, devices just turns on to the black screen like normal
the only problem right now, I cant retrieve the uid
adb
when I type adb devices, nothing shows up
A500 manager
tried to the use the uid retriever tool however it just stays blank, same for the bootloader
it says it detects the A500 in apx mode
usbdevice view
shows no serial number for this device
I see there is a A500 motherboard on ebay (cant link to outside links...)
"Acer Iconia A500 Tablet Replacement Parts - MainBoard - 32GB MB, H6000 001 PBJ20"
"Complete with Android 4.x installed, 32GB memory and ready to install and boot."
could I get that and just replace the whole mobo and it will work fine?

OK just clarify - black screen, that is, nothing at all displayed AND Power Light ON??
IF u r in apx mode then
U have a couple of options
EUU flash back to HC 3.2.1 or
apxFlash to ICS
Everything you need for doing this is in my cpuid guide link in my sig.
open apxflash tool do not connect your tab Yet
Go as far as the enter apx mode
Now connect your tab to yr pc
Windows should install apx drivers
Once installed. try clicking blue arrow first
If u don't see the do u want to flash window then
You'll need to click on the "enter apx mode " button instead then
Click blue arrow
Hopefully the PC and tab are feeling pretty friendly and decide to take each other on
The tab should flash the bl and install recovery.....u should be good to go from there!!!
EDIT you can try cmd prompt on nvflash folder
Run a500.bat or.bat file that should kick you to bootloader mode
its really important that your screen display something in white letters!!
Entering Acer download mode OR
Entering apx mode
The flash will fail if u don't see something like this. This holds true for all methods

Wayyyy outta my league m8. Sum1 else will know....

yes, its just a black screen, no vibration, no boot logo, no letters or words on the screen, backlighting for the screen is on, and the power light is on
when I press the blue arrow in a500 apx flash tool it asks me for my SBK, going to that generator site it then asks for my UID which I cant retrieve

if you do not have your cpu id and
if you do not have access to adb and
you're stuck in apx mode
then things are looking grim.....
the only way to get into your tab without yr cpuid is fastboot
but you need adb working for that
someone else was stuck in apx mode a day or two ago, try a search...maybe...

I'm sorry guys I was a little off of this thread .
I will be glad to help you guys to get your UID or any problem that you have even though I don't have the Tablet anymore.
Thanks for all and God bless you all.

There is no way to fastboot the tablet in that mode, the only way is to get the UID and then decode it and NVFlash the Bootloader after it is done then put ICS or HC and the EC_ROM files and the tablet will be working again.

I'm gonna throw in the towel and just buy a new mobo for cheap, it seems im screwed without the UID and cant retrieve it either
I wish the previous owner would have gotten the UID beforehand
thanx for the all the help though

[Solved] Mystery bricked tablet. Black "android systems" screen

I bought an Acer a500 tablet a few days ago not knowing how broken it is.
After loads of research and attempting different techniques I still haven't had any progress.
The software issue:
When booting up the tablet, it goes to the black screen with "android system" at the top and power off/ shutting down in the middle of the screen.
Fixes I've tried:
1.
Since I don't know anything about what operating system is on this tablet, I have been blindly flashing different "stock" (from Vache) versions of HC.
--The android logo with gears shows up, the green bar loads but freezes when it gets 1 cm away from finishing.
--After turning off the tablet and booting it up again, "updating bootloader shows up on the upper left hand corner of the screen. Then a message pops up saying "apk installer: all pre processes complete". Then it returns to the black screen.
2.
The tablet will not go into apx mode (using the reset botton at the bottom).---Fixed. I didn't execute the steps properly. Apx mode works fine.
3.
I plugged the tablet into an older windows laptop and the computer could not install the correct drivers to sync with the tablet. Again also my lack of knowledge. I installed drivers from Acer.com
4.
These two guides seem to be exactly what my problem is but I can't seem to make sense of them:
http://forum.xda-developers.com/showthread.php?p=24531880#post24531880
http://forum.xda-developers.com/showthread.php?t=1572622
This is as far as I've gotten.
Other complications:
--The battery is dead. I have to use it while plugged in by the charger.
--Most of the thread that I have looked at use Megaupload as the source of downloading their files.
--The original owner of the tablet will not help me out. As I stated before, I don't know what version android OS was on here before it was bricked and on top of that the original owner won't answer my questions. As far as I know though, this tablet is not rooted or has anything "non-OEM" installed in it. The story goes that this tablet was bricked when the owner tried to "update" it. Before that, it was functioning perfectly.
-----It looks like Darvis is having the same issue and frustrations I'm having but reading his threads makes me think that this tablet is a dead end.

First off......I hope u didn't pay much for the tablet.
Secondly the guide above looks pretty straight forward but maybe this is one of the ones that has files at megaupload?
I know that the ra recovery and timmydean's files are accessible as I have downloaded both of them.
Maybe someone who has done this previously will chime in and get you the other file if it is indeed unreachable.

I would suggest trying to connect the tab to a Windows 7 PC after installing the USB drivers from ACER. Then check if your device appears in the device manager. As long as you have its UID you can flash the tab from the PC with one of the EUU tools - check my signature on "how to revert to 3.0.1" or TimmyDean's thread which offers an EUU with rooted HC 3.2.1 (it's linked in my thread as well).
How exactly did you try to get into APX mode?
p.s. I have the EUU files if you can't access them from the threads links. I can send them to you.

getting into apx mode
When I perform the steps (hold reset + power for 3 secs then release power); the tablet turns on as it usually does. It goes to the Acer screen, then android and back to the black home screen. My computer responds by saying that it is "installing drivers" but it "fails to install drivers". At the same time I have the DND.exe open and it does not recognize my tablet.
I'm trying to follow the instructions from the root 3.2.1 v4 file.
I can't perform the first step where it instructs me to turn on Usb debugging. The problem is that I can't open the settings by clicking the clock. Nothing happens.
I realize that one complication of my tab is that it will not charge. The battery power is below 15% so none of these fixes might not be effective for me. That might be the ultimate problem?
CyaN1de-
I paid $100 for the tablet. As of this moment I feel like I paid too much.
Thank you both for you quick replies. I have to say that most of the problems that I'm having is because of my lack of experience but I'm learning. I hope I fix this tab soon.

if this dont fix it, i'll give you what you paid for it;0
someone posted a while back that a hard reset fixed the android systems screen error
not sure where you're at now but no harm in trying it
Try using hard reset:
1) Turn off your tablet,
2) Rotation lock s to your left;
3) Press Vol+ (which is next to rotation lock) and power on simultaneously
4) As soon as the tablet vibrates you can release the power on button and you
should start to switch rotation lock left and right till you see
Erasing Userdata...
Erasing Cache...
Vol+ is still pressed;
5) The tablet starts to format
6) Your tablet will be as clean as it can be.

Thanks for the suggestion but I didn't accomplish anything by hard resetting it. I've done this many times and nothing has changed.
I haven't given up on unbricking this tablet yet and even though it's frustrating I'm learning from the process. If I decide to sell it, I'll contact you Dibb.

i've seen the 2 methods u described but i've not seen anyone else have success with it apart from the OP'ers - seems OTT to me but hey if it works for ya...
I've used timmydeans method ALOT on HC it never failed to work and that includes reverting back to HC from ICS - if it doesnt work for your issue then id be tempted to use blackthund3rs APXFlash Tool and civato's HC_ICS_Bootloader zip to flash a new bootloader and rom package on yr tab - but for the moment we'll run with td'sv4 - if drivers fail to install then believe me, its a good sign
try this:
I know you-ve probly done it but u need to do it again:
reboot everything, then reinstall acer drivers (yeh i know)
fire up ya tab but dont connect to yr pc just yet -as you said you
doubt usb debugging in enabled so we'll try another way around it
run the prgb20.exe it will scan for the new image but not find it becos youre disconnected...thats good....
after maybe 5 -7 minutes of scanning for the new image - it will show a
window "cannot detect yr iconia tab"
and instructions for getting into apx mode - go ahead connect usb put the tab into apx BUT don't click next until....
the drivers will try to install, dont let windows search but let me choose
(off memory) choose device and adb or android ph should show up here
the acer boot/recovery drivers should install...maybe even under USB Controllers
once they do and only when they do click next to put tab into:
acer download mode.......
as i said this is worth a go,,,,how about the update.zip have u tried that.....
else the only other way i know is apx flash....ya still need to get into apx
mode and if u cant then ???? sometimes youll try something over and over
and then out of the blue it will work...you'll swear you never did anything different , it jsut worked this time.....
hope you find some joy

Thanks Dibb for your words of wisdom. I've put it aside for now but I'm going to pick it up in the morning.

As addition to what dibb_nz said - Windows 7 would do the trick - I'm almost 100% sure you'll be able to connect in APX mode with the drivers properly installed. Then use one of the EUUs.
Drained battery really looks like the ultimate problem now because as far as I know you cannot charge the tab in APX mode - haven't tried that. Eventually I would suggest to crack the tab open, remove the battery and charge it somewhere - I don't know alternative ways but...may be another tab or you own charger with proper connector ...
http://www.youtube.com/watch?v=xvXihNIdQ1M
p.s. 15% power ... seems enough to flash through the PC...but who knows - don't waste them and get everything you need before starting the procedure.

no probs m8 hope u have better luck tomorrow
if u wanted to try the EC method i have those files if you want them
good luck m8

So I went through all these steps and the TD's V4 tool finishes updating the tab. But then it continues to the same black, android systems screen. And afterwards the tablet won't connect with the computer.
I am currently downloading the update.zip so i'm going to see if that will work.

do u get on yr tab the big 'PASS' in white leetters or "entering download mode" at all???
think we're beyond update.zip if EUU failed but you can try it -
you can get to apx which is a start - getting a new boot/recovery image on there is the main priority I think...as i posted earlier i've only ever seen a fix for this problem work for 2 people, so on new ground here....
But anyway check out the APXFlash method/walkthru in my sig....all the info is in there and the links to the required files ....do we know if you're on HC or ICS B/L????

I got the word pass; now using recovery mode to flash a rom.
not sure which bootloader I have.
I am using:
Acer_A500_7.006.01_COM_GEN2: http://vacheandroid.com/files/Acer_...1_COM_GEN2.zip
But after it says install from sdcard complete it also give me the message:
E: Can't mount/ dev/block/mm....
E: Can't mount Cache: recovery/log
E: can't mount open cache: recovery/log
E: Can't mount /dev/block/mm...

dibb_nz said:
yes if you're talking about the stock roms from vaches thread, you need the full rom package - you cant just use an 'update' package as they need a full rom to work properly....
for instance my original HC3.2.1 Stock build is 7.014.15_COM_GEN1
and theres no FULL Rom for 3.2.1, so i have to use the HC 3.2 FULL instead
.....Acer_A500_7.006.03_COM_GEN1.zip
Once flashed, thankfully I recieve the 2 small OTA Updates to get up to 3.2.1 again
Another couple of days the ICS OTA d/l'ed and installed with no probs....
is that clearer or am i making things worse????

What I've learned from this whole process is that all of the obstacles I'm facing are due to my lack of knowledge. Thanks for sticking with me Dibb. I can't thank you enough.

I could never get mine into apx mode with the usb cable plugged in. So try that if you haven't. And it is literally hold reset, then press power, without letting up on the reset, release the power button after 3 seconds (use a watch or timer!) then one more second before you release the reset... It does work, but the timing has to be close. It must have a tenth of seconds or less tolerance. Very picky... I've done it on 2 different a500s so far and I am heading to do another tonight. If it doesn't work I'll be right back!!!

Crikey just as I finished typing "....land"
Back to more important matters..... whr u at m8????

None of the roms I've tried to flash go to completion. I'm stuck at trying to flash different roms from recovery mode. Not much luck with what I've tried but I'm going to try more before I give up.
Are there any particular roms I should try more than once?
Or why am I getting the "error" messages stated earlier?

None of the roms I've tried to flash go to completion. I'm stuck at trying to flash different roms from recovery mode. Not much luck with what I've tried but I'm going to try more before I give up.
Are there any particular roms I should try more than once?

recovery mode???
u need a new boot and recovery image on that thing
the HC EUU based flash arent working even tho u got a PASS on screen after TDv4
So HC based methods arent up to it. You need nvflash/fastboot.
We need ICS with the unlocked bootloader it has access to another level below where HC worked because HC b/l is and always has been locked down.
If ICS cant fix it, I have no idea what will and my offer to buy is off the table!!!!
check out civatos guide and ready yourself for nvflash via zip files in that post or blackthund3rs APXflash tool, with a complete tutorial for using it, all links in my sig.
good luck

Just to chime in with a tip on getting google drivers to work.
When getting any device not recognized, or driver error, generally I go into windows device manager, select the unknown or offending device, update driver, only I choose which driver to use, and ignore the error message where it says "may not be compatible with your device", and use it anyhow.
I get that occassionally when swapping back and forth between devices.
Also, battery not charging and display errors, are usually a sign of EC Power control. So you were on the right track about that. Once you get a rom up and running, if the batt don't charge, then there are some EC flash's you can do from CWM.

Back at it again using BT's nvflash tool. And tablet is still bricked.
I've tried a few different bundles and none allow me to operate the tablet. Everything goes smoothly and I get "pass" at the end of the process. When I go to reboot the tablet, it gets stuck at the black start up screen.
Found another lead: http://forum.xda-developers.com/showthread.php?t=1579490
Sounds like he was in the same situation as I am but has a bit more skills and knowledge dealing with problem solving.

You say you were able to flash roms. So apparently recovery is working OK. Have you tried flashing civato's flexreaper? It has code that will detect whether you bootloader is HC or ICS. You may just be flashing a rom that doesn't match your bootloader... I know I'm jumping into the middle of this, but it's just a thought.
Also, when you did the hardware reset with the rotation lock switch did you get the confirmation that it was, in fact, being wiped?
Failing all that, I'd be willing to take it off your hands for spare parts...

Download a stock acer image and place it on a MicroSD under the name of update.zip then boot into recovery
But yes it is the wrong forum section - should be in Q&A doesn't bother me too much but it irritates devs because it's the development forum

I'm not sure what may have happened but the easiest way to fix your tab is to downgrade back to HC using an acer utility called an "EUU". you will need your cpuid for this so i hope you have saved it somewhere.
Look here for 'jazzyjames' tutorial How to rollback to HC - for instructions on how to do this and a link to timmydeans HC EUU - also take a look thru my cpuid post (link in sig) for loads of info and links and even how to get yr cpuid if u dont have it

thanks i tried it and follow instructions numerous times. evry time i get to the step where it says "entering acer download mode on my tablet" on the EUU program on my laptop it says it "failed" so i try and try again with the same results. im running out of options. i dont know what to do.

maybe give this a shot. I've never had to use it myself but it's probably worth a shot.
How to unbrick your tablet -
http://forum.xda-developers.com/showthread.php?t=1699277

oh heck that doesnt sound too good, i've not heard of the actual EUU "failing" guess thats the result of the usb issue you spoke of!
The "update.zip" method, you have 2 choices here See this thread for all the Official Acer Stock Roms - Ensure you download a "Full" rom and not just one of the update packages....instructions are in the first post...
You need to extract the update.zip and it may need to be decrypted as I said instructions for all this are in the OP!!
method2 - I've tried this once!! I got pretty frustrated real quick. Its a buggy chinese rom - took me a good hour to finally get into flashing a recovery, but it did work and plenty of others
have posted success with it... drkalo has a guide right here
Failing that m8 yr options are very, very few...
Try on a different computer so we can rule that out...or not!
or try to troubleshoot the usb issue....there are the only 2 ways via sdcard or pc/usb...
thinking about it now, in your post you said
"i cannot use usb because my computer wont read it not even after downloading drivers. anyone help me please?"
Not sure I follow, wouldnt have thought you'd get all that way to download mode without USB drivers to begin with.
You have debugging enabled in settings and you connect your cable to your pc but your tab does not show up on your PC in Device Manager???
Are you still on the stock bootloader??what about recovery??

this is what comes up
this is what comes up after trying this methid

So this window that pops up saying 'failed' and with instructions to go into apx mode - did u do this? what happened after you did it?
I haven't seen this particular error but normally with the downgrade process you do not have yr tab connected UNTIL you see the "cant detect your iconia tab" window (with similar instructions to enter apx mode manually) did you see this window at all? you do not enter your cpuid until AFTER you have put yr tab in apx mode and connected to yr PC, then the green status bar shows and then you should see "Congratulations".
To check you are in apx mode your tab screen is black and the power light is ON.
Now before you connect yr tab to yr PC open up Device Manager (pc) so you can make sure the apx/usb driver loads when you connect the cable - it will show under "USB Controllers". Once you can confirm the drivers are installed then you should be all good
The drivers are a bit of a pain as there are different ones for each different 'mode' of your tab i.e
USB driver that allows you to see the contents of yr tab from yr PC
ADB driver that allows yr tab and pc to communicate by sending commands to yr tab via yr PC
APX Driver which you normally only see while running HC, but yr PC can sometimes report an error with the "apx device" if the drivers have not installed properly
Acer Boot/Recovery Driver which NEEDS to be installed for any type of nvflash or EUU flash to be successful
Fastboot Driver if you have flashed bootloader v3 up this driver will load when you enter "Fastboot"
This is why folks have trouble with drivers and why we keep telling them "reinstall the drivers!!!" The Acer drivers from acer support AND the Google adb drivers which you can get from the first post of my cpuid thread (link in sig) the zip also has the fastboot drivers and saves you having to download the full android sdk. Having device manager OPEN while attempting any type of flash definitely helps you see whats happening - or not - driver wise...

SOD and no root and unable to connect to a pc!

Ok so I was running taboonay 3.0d and I thought I'd have a go at Thor's rom. Flashed it wasn't really into it few things missing that I like in taboonay. So I then restored my back up. All hunky dory.
I then flashed a zip for scrillax v8 bootloader. It seemed to work fine, tablet boots up and rom running fine. I then tried to get to recovery and it's just not happening. Acer recovery says it cannot get root access. When I reboot I can get into the bootloader menu but none of the commands work. I can't get into the recovery menu at all no matter what I do. So then I figured I'd give Blackthund3r's root tool a go. Got everything ready on the pc including latest acer drivers. Now the tab isn't showing up on the pc either. I know some others have had similar problems but no solution was found in the other threads and considering that I probably screwed up badly somewhere along the way I thought I'd start this thread where you can all point out my ignorance and stupidity without bothering anyone else :silly:
Any help?

Any advice at all would be great, I have reinstalled drivers for tab but still no go! I'm on a old xp pro laptop. Everything else connects to the usb port and the cable is working fine

If you can't get to Recovery, you will need to reflash that.
But first thing is first. And that's the driver issue.
With the tab plugged into the PC, go to Device Manager, and see if it reflects there. If not, you will probably have to reload the drivers. You have a choice, which is the Acer Driver installation, or you can try the Google USB Android drivers. Generally I have had not much luck letting windows search the PC, so I usually install them manually. You can either;
a. Direct device manager to look in a specific folder for the google drivers, or;
b. In Device Manager, when you choose update drive, use "select from list" and see if the acer drivers show up there.
Generally, when you install the acer drivers, you should "right" mouse click the install file and select "run as administrator".

Thanks md will give it another go
My device manager has no option for select from list or update drive, just scan for new hardware. Nothing shows up for acer.

Ok, now I run Win 7. But XP should be similar.
Are you saying in device manager, you do not have a device with an exclamation mark when you plug the tab in???
If you do, then right click the exclamation mark, select properties. Then the Tab "driver". Next, select "update driver". Then, "browse my computer for drivers". You should get the option to "select from a list".
If your PC does not detect the tablet at all when you plug it in, then it';s a different issue. It's what we call a USB Brick. At first guess. Usually easy to fix on the 500.
Can you start your tablet in APX mode? hold the pin reset, press and hold pwr. Count to 3, and release pwr, then 1 second later, release the pin reset. You should have a black screen with the pwr lite on.
I'm thinking you might want to do the manual flashing of the bootloader + 1.7.3 recovery. Obviously the bootloader V8 flashed, or it wouldn't work at all. Civato has instructions for manual flashing of the bootloader and recovery. Note that I HOPE you wrote down your UID number somewhere. As you will need to convert it to the SBK.
MD
EDIT. One more note. When you boot to the bootloader menu, in your case, probably the only option that will work is "fastboot mode". When you select it, the menu should go away, and it should say "fastboot mode". Then plug into PC and see if windows detects it in device manager. If so, you can fastboot a recovery image to it. Note, that for fastboot to work, you must have the Android SDK installed on your PC. Because you will have to run the fastboot commands from a command window. But for now, check to see if you get to fastboot mode on the tablet.
Sorry I can't spend a lot of time, as it';s late in moscow. Job tomorrow. But Skirlaz_CZ can give you the commands to fastboot a recovery in his bootloader thread.

Thanks MD I can get into fastboot mode so I'll try that one first. I didn't write and numbers down unfortunately. I was following a thread on tegraowners to install the bootloader which made no mention of making records( I'm a simpleton that needs to be led by the nose)
I appreciate your input

Ouch! No UID numbers. That hurts. Look in your old CWM recovery backups (if you have) on your EXT SD Card. If you were at one time running a more recent version of CWM, You might have them in the recovery folders. The more recent recovery programs in the backup folders, it's called UID.txt. You have to have this if you use NVFlash. No way around that.
With Fastboot, you don't need it, as you will fastboot the recovery image. If successful, that should allow you to boot to recovery, and flash one of the custom roms. Make sure you do your wipes as in the Rom install instructions. I use CWM 1.7.3 (I've been too busy to try EZTerry's or the TWRP versions. But CWM works good so far.
If not, well, there;s always the update.zips to get a stock ICS on your tab.
Either way, we'll get you running, so don't worry. Just takes a little time between time zones, work, and family

You're not wrong there! I'm doing the whole ikea/home improvement thing with the family today. I'll try the fastboot later

Ok MD so the fastboot doesn't work at all. I installed adb using knives and forks and that couldn't pick up the tab for drivers installation. My head is wrecked! checking backups for numbers now
0x037c62074 and a few more got it

You should be able to do it if you already have V8 Bootloader.

MD - Have you a link to download cwm 1.7.3 img? The download link in tegra won't work for me.

Sorry I was away. Did everything work ok for you? All running? (been trying to chase down my rom issue)
If it says "waiting for device", then you need to check your device manager, and make sure the correct driver is recognized. (APX, Fastboot, Recovery, Download, etc). Usually, I can change drivers while this is happening, and the process will complete.
MD

ok I don't mind admitting that I'm totally lost here. Nothing resembling the tab is showing up device manager so how can I check the drivers?I've been playing around with device manager for a while now and I can't find any way to do what you suggested
I've uninstalled and reinstalled the drivers again and again. Nothing! Could it have anything to do with me having a gateway? I wouldn't think so because they're the same inside.

Righto, no matter what I do the tab won't show up. Obviously can't check the drivers without the device showing up so I really am at a loss.
Even if I try the manual flash from civatos thread I will still come up with the same problem. No device no can do

be worth checking you still have usb debugging enabled m8
EDIT: The only other thing i can think of is to put yr tab in apx mode manually (press and hold reset button then press and hold power button, when the pwr lite comes on count 3 seconds and then release it, hold reset another second and then let that go) - you should have a black screen and power lite is on) now connect yr cable and see if the pc picks up the acer boot/recovery driver under usb controllers .
If these drivers install then I'd attempt a rollback to HC using an EUU, at least this method depends on yr pc not seeing yr tab. I'd only attempt this tho if the boot/recovery driver is installed and listed in dev. manager.

Sorry Guys but another A500 Bricked APX mode only

Hello,
I am another unfortunate user who has bricked his tablet. I installed Jue11 Ram Manager Plus and it asked to reboot my tab. On reboot it was bricked, flashing the android logo and not going any further. I have tried everything listed on the site to get my CPUID to no avail. have followed all instructions including trying to retrive using Ubuntu Linux, A500 Flash Tool, (which tells me it is in APX mode but returns a blank serial), NVflash gives a device not found. Any help? I am technically saavey on PC, Windows and the like, but fairly new to tablets.
A little more info, using A500 Manager it reports a500 in APX mode then acts like it is retrieving the serial but comes back blank. Nvflash reports device not found. Using Ubuntu gives errors but reports all needed packages are installed, (not a Linux Power User so could be an ID10T Error on my part).
Please, I appreciate any and all help.
