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...

TF101 "bricked" and I can't restore it

Hi !
I am posting here because I'm a bit desperate.
I have a B40 TF101 and a B70 dock (I bought them separately).
I have tried to flash an official ASUS update downloaded from their website using EasyFlasher.
The thing is it did not work and now my tablet won't boot at all.
All I can do now is start APX mode. The wieird thing is that it does not work with every computer, some detect my tablet and some just don't. Note that it only works while the dock is connected. Without the dock, I can't get the APX mode to be detected on any of my computers.
On the only computer that detects it, I have tried pretty much everything I found on the web to restore a rom, using easyflasher again on windows, then juste wheelie's restore.sh script under linux.
Using easyflasher I can't download the complete rom (it stops at uploading blob.APP, saying that a timer has expired or something like that). I tried to simply install a custom recovery image, to be able to flash an update.zip from there. The flash process seems to go as expected but I just can't reboot into the recovery, the tablet only boots into APX mode.
I am really stuck there, and I hope someone among you will be able to help me or at least tell me there is still hope
Thanks

If you aren't getting many replies here, I would post this on the Q&A section.

You need an NVFLASH rom
even if it doesn't seem to have detected APX mode try it anyway

You have to install the apx mode drivers for your device in order for it to be detected by the computer plenty of tools available to recover your device just search for some good ones will even install the apx drivers for you for example this tool http://forum.xda-developers.com/showthread.php?t=1185104

[Q] Stuck at stage two (unlocking bootloader)

Hi guys !
I'm trying to install a custom rom on my A500 but I don't get to unlock the bootloader...
I stuck with blackthund3r tool at :
Flashing Bootloader (EBT) stage two - uploading image...
I'm on ICS OTA 4.0.3 and the bootloader is 0.03.12-ICS
I follow all the threads talking about that but did'nt worked...

You need the drivers installed
1. Acer website for the acer drivers
2.zip file attached for google/fastboot drivers
Ive attached a .jpg too, u need to have the apx device listed in hardware/printers as shown
3. with apxFlash try dumping your ".bct" when u see that window
4. you can try the afterOTA tool too...
5. if the auto tools dont work then you will need to rollback to HC using tdv4 EUU
6. have a look thru the OP of the cpuid thread for more background info on all things acer http://forum.xda-developers.com/showthread.php?p=25429111#post25429111

I've never had this much trouble before.
Ok. A little back story first. I'm not a moron, I have a myTouch 3G Sapphire 32a Fender rooted using the gold card method, LG G2x - P999 Rooted running CM10, and a SGH-T999 Stock rooted (That's a Galaxy S3 for those who don't know).
I have a friend that got an Acer Iconia a500 tablet a year ago. He's not a power user, doesn't know anything about rooting. All he did was play games on it. One day it wouldn't turn on, the screen was blank. Occasionally it would freeze at the Acer logo, but it would never boot up.
Now it's stuck in APX mod due to him pushing a bunch of buttons(idk how he got it into APX mode so don't ask), so there is absolutely no way to boot the tablet. He never turned on USB debugging, and I can't get into the tablet to turn it on because it's stuck in apx mode.
I must stress this!
I have been working on this tablet for 3 weeks now, and read countless posts about how to fix the exact problem that I'm having with this tablet, the only drawback is: step 1 is always, "Turn on USB Debugging." That is IMPOSSIBLE for me to do at this point.
Here is list of what I do know:
Hardware - Acer Iconia a500, APX Driver Version - 1.0.1.0 Released 4/1/2010 Shows as APX in Devices. Shows as Acer USB Boot-recovery driver in device manager.
Software
ADB info - Android SDK rev.20
ADB ver 1.0.29
Windows 7 64-bit completely up-to-date
Commands: adb get-state, get-serial ------- returns, unknown
Commands: adb remount, root, usb ------- returns, "error: device not found"
Command: adb devices -------- returns no value at all.
Programs used for rooting - AfterOTA 1.09, EUUS v3, blackThun3r A500 Manager
I have the CPUID, and SKB (I was somehow able to acquire those in one of my attempts to flash the stock rom)
What I don't know:
What version of Android OS is on the tablet. I'm pretty sure it has ICS, but he was deathly afraid of downloading any updates, even app updates even though I told him that all updates should be installed a.s.a.p. So there's a chance that it's still running HC.
Now here is my problem other than being stuck in APX mode. I have tried AfterOTA, it won't detect anything past Driver Installed on the Tablet information screen because USB debugging isn't enabled. So I can't use most of the functions of that program.
blackthund3r APX Flash v0.4 - Will get the tablet into the bootloader mode where it says:
Acer Iconia APX Mode in the upper right with a glowing yellow Acer logo in the center of the screen, nothing is flashing like the APX flasher says, I have reinstalled the drivers hundred of times with the same results.
Hangs at, "Flashing Bootloader (EBT) stage two - uploading image..."
EUUS v3 - Says, "Acer Iconia not detected"
(I had a screenshot posted here, but stupid forum limitations wouldn't let me. You could see what's going on if it let me post this.)
I do the reset procedure and it just goes back to the same message.
It will go into a screen on the tablet that says "Entering Acer Download Mode" Then EUUS tells me to do the reset procedure again, and this is a continuous loop that results in nothing being flashed. If I ignore that message and just continue nothing happens.
I also have a file called a500-hc.bat that runs nvflash and it gives an error that leads me to believe that a partition on the tablet is corrupted. Everyone says that EUUS v3 should fix this and flash back to original stock, but it obviously doesn't work.
Any help that I could get would be greatly appreciated. If you need any more information, just ask, and I'll do my best to get it. The tablet is (for lack of a better word) bricked, so I'm very limited on what sort of software info I can give you straight from the tab. Please Please Please help. And thank you in advance.

[Q] Stuck at ACER logo

So, i have been tasked with fixing an acer tablet. I have been searching these forums for a few days to try and figure out how to fix this tablet.
The issue is, it sits at the ACER logo screen (this would be an easy fix on my GNEX). Sifting through the threads i decided to post here to help me move this along faster.
I can get the device into the bootloader. I am presented with the following -- Bootloader v0.03.12-ICS: Starting Fastboot USB download protocol. I can not use fastboot as the bootloader is locked and i can not unlock it (from searching i found i need to installed a patched version, and that is where i am running into issues).
I can not figure out his CPUID. Since the system will not boot, i can not use a terminal to get it. this tablet was completely stock so no CWM on it. I thought i had it showing in ADB once, but i have never been able to get it back into that mode. (any tricks, i thought it should work if i am in the bootloader, i installed the driver from acer, but i does not list any devices, tried another usb port).
I have also tried putting an update.zip file on the sd card and booting into stock recovery, but that ends up with an android with the red ! mark above its belly.
so, i ask you guys for some help. Is there any way i can fix this tablet?
EDIT:
when i do a fastboot devices, i just get a ? fastboot. and nothing for ADB
The tablet also responds to fastboot commands, mainly reboot, anything major and it tells me denined (that it is locked)
EDIT2:
I have blackthund3r A500 manager running, i got the tablet into APX mode, at the bottom it says A500 detected in APX mode. When i click Dump dmesg to desktop, it created a file but nothing is filled in it. When i clicked view dmesg, it says - error: device not found.
Also, under device manager i am seeing a device called Acer USB boot-recovery driver. When i get it into bootloader it shows up as a ADB driver.
Thanks

I'm going to assume you have an A500 and NOT an A501.
It appears your stock recovery is probably also working, as if it weren't, you'd probably go to APX mode. As it is, you get the Acer screen.
Regardless, here's a list of A500 ICS full update files on my Dev Host server. I've already decrypted, and named each one a little different so you won't get confused. Put one of them (the zip file, DO NOT EXTRACT) on your external SD card. Then power on your tablet holding either PWR & Vol+ , or, PWR & Vol-. Can't remember which for stock recovery. See if the update will install. You'll see some text in the upper left corner, then you can release the buttons.

Now, you may have to try more than one of these updates. Some work, some don't. But try each one and see if it completes install. This is about the easiest way to begin with.
If it don't work, then probably have to get a linux ubuntu install to get the UID number.

The updates did not work for me (was I not supposed to change the names of the archives to update.zip?), and I have the exact same issue as the author of this thread (minus the part where he's doing it for someone else, It's my tablet). Is there a way to get the CPU ID on XP? I do not have access to a Ubuntu installed computer, although I have Virtual Box installed on my XP and when I set up Ubuntu on it, it did not work.

thank you
thank you, it worked for me.
i formatted my SD card, and i renamed the file i downloaded with ------> update
i copied it to SD card.
i pressed Power button + Volume button (-)
it took me less than 2 minutes to update.

I found a partial solution to the problem. you need to download a file archive called babsector.rar. It has two batch files in it that will basically do the same thing as blackthunder's tool, the only problem being is that the tool won't work for me. The other part of the bad side is that now I need help to flash a kernel onto mine without the tool.

Hello,
I have been asked to troubleshoot an ACER iconia stuck at boot logo. I am not sure if what I read here is applicable to the model I got. Here is what I can read on the label at the back of the tablet :
ACER iconia One 10 B3-A20 Model A5008
FCC ID:HLZA5008 IC: 1754F-A5008
So is "A500" topics relevant for that tablet ? I don't see any topic about "iconia one 10" or "A5008" ...
Thank you for your answers.

Stock firmware reinstalled
Replying to myself !
Found stock firmware from that Acer link, entering model etc.... (change language FR to what you need).
Then copy downloaded file to SD-CARD, and restore firmware from the recovey menu (pressing "Vol Down + Power" to enter.
Then Restart ... Cool.

Acer Iconia A500 Stuck "Black Screen"

Hi,
I have an Acer A500 that I'm trying to resurrect after my son tried to root the device. I'm new to this and have checked many sites in search for a solution to this issue (if possible). I'm not sure what all my son did to this device so please bear with me. After reviewing several posts I find my issue unique where as some members may have simular issues I still have not been able to isolate my issues.
The issue: The device is stuck in APX mode with a black screen.
1) The Power Button does illuminate when powered "On" but the screen is "black". There is NO vibration when turned on.
2) The Battery life is good on this device.
3) When the device is powered "On" and connected to my PC the "Blackthund3r A500 manager" display "A500 connected in APX mode. Please Install drivers!"
4) Using Ubuntu I was able to get the "CPUID" and with "SBCalc_v1.1" I was able to get the "SBK".
5) Performing a startup utilizing reset button and On button has no effect
6) Going to "On" with the Vol + pressed has no effect
7) Using "AfterOTA 1.09" on the first "Info" tab under "Tablet Information" it displays Driver "OK driver installed", under USB it displays "ERROR - connect USB cable and enable USB debugging". Everything else displays "waiting for connection". Pressing "Reconnect Tablet" has no effect.
So far that's all I have been able to do to this unit with NO success. I welcome any feedback on this issue.

bricked tablet
best bet is to use babsector
it will install recovery and unlocked bootloader and format all the partions back to default
then you can flash updated recoveries roms etc, from there

Thanks for your response. I'm not familiar with that with that program. Will it work even though the other programs show the device not being connected? (I've Used several USB cords with the same result). Where can I get that program?

you will need to install the acer usb drivers to your pc
if it's win 8/10 then you will need to first disable signature enforcement
http://forum.tegraowners.com/viewtopic.php?f=10&t=2196
babsector is a simple forum search

I complied with the driver settings and still no joy. The device stays in the APX mode and nothing seems to helps on connecting the tablet to the PC. Is there any script that will manipulate the tablet setting for connecting using Ubuntu?

can you give the steps you used to obtain the cpuid? im stuck with a black screen. have ubuntu installed on a virtual system, when i run the command for apx the file that comes back does not have the cpuid.

You can recover the CPUID by following the instructions at this link http://forum.xda-developers.com/showthread.php?t=2096826
You can then convert your CPUID to SBK with the app here http://forum.xda-developers.com/showthread.php?t=1810618

thanks for the reply. i was already trying out all of those guides. it didn't work at first but i changed a few lines of coding and it worked!!! i was using a 32bit ubuntu, made the suggested changes and also added a different line elsewhere. if anyone needs the apx.c file i used with all the changes already made. let me know.
