Hello, and thank you everyone for all the helpful posts on my device the a500.
I really like my tablet, I know it is not the newest out but I really like it and the screen size is nice too for the price I think it is great. I do have a problem tho, I want to try out some custom roms, and to do that I need to install a custom recovery like CWM, and I am having a really hard time of it. I was able to get root easy enough using an archive I got from this site (thanks) it used adb and pushed some files, then I installed Superuser, and Titanium Backup, and all was fine, then I installed acer recovery installer to install Thor's CWM 1.7.3 and found out that I have a locked bootloader 0.03.12-ICS, so I figured ok it should be easy enough to install a patched or unlocked bootloader, I was wrong... I have APXflash and afterota and have tried all the methods I can find to try to unlock my bootloader and nothing... with afterota it just hangs on flashing kernel 3/5 and with apxflash the same it just hangs forever the progress bar does not move. I am not the most savvy with these kind of things, but also I am no dolt either. I dont know what the deal is but my device just wont accept a flash at all I dont understand why, I used the stock recovery to flash an update.zip I found for my a500 thinking that after that I would be able to use apxflash, or afterota, but still nothing...
Here is my device info:

If anyone has any idea why my tablet wont accept a flash I would love and appreciate any help at all here. I was wondering if I could manually flash my bootloader with dd in terminal emulator? like this:
dd if=/sdcard/bootloader.blob of=/dev/block/mmcblk0p4
or is that wrong and I just made a paperweight?? Like I said I am pretty new to tablet mods, and I am just totaly stumped here its like acer has my bootloader on double lockdown... if there is an update.zip out there that would use the stock recovery to unlock my bootloader that would be awesome, then I could install thor's CWM touch and check out some fancy new custom software .
Again thanks to everyone for all the work you have done and shared with us here, and thanks too for any help any one has for me

well I tried flashing with nvflash but still no luck here is the message I get:
Flashing bootloader: bootloader_v8.bin ...
Nvflash started
[resume mode]
Formatting partition 4 please wait.. Command Execution failed cmd 13, error 0x1
0002
FAILED!
command failure: format partition failed (bad command)
bootloader status: unknown operation (code: 1) message: flags: 0
Nvflash started
[resume mode]
Then the program just hangs while the tablet sits in apx mode with the acer logo....
I am still just completely stumped on my I cant seem to find a way to flash the bootloader, I can flash the recovery, which then wont work with the locked version of bootloader I have, so I flash back to the stock recovery until I can get this bootloader flashed...
has any one encountered any thing like this? I would really like to figure this out and flash a patched bootloader to my tablet.
I have not had any problems like this on my phone, its an older one an LG ally, but I didn't have any problem with it at all and have cwm on it and run a very customized version of BioNX on it with the Next launcher, I really like how that all went, and I figured I would be able to customize my tablet as well, but until I can get past the bootloader, all I have is root, which is good for some things but without access to the custom recovery there is a limit to what I can do, and I am not big on being limited, hehehe. any how any help at all will be highly appreciated
Thanks
A500 Bootloader unlocking
Well I sent my A500 in for repairs, no nothing with the software, and I did not brick the tablet either, but a little drop and cracked the plastic shell, so since I bought insurance on it in-case of damages I sent it in to get the plastic shell repaired for free and they gave me a loaner to use while I wait for my A500 to be repaired. They gave me an A200, and so far I like the A200 it is basically the same minus the camera, it did take an extra second to install the right drivers for it to connect properly to my Windows PC ( I had to download adb drivers "Acer.rar" package, and direct device manager to the folder to get all the drivers installed. but once I did, I found a package to unlock the bootloader, root the device, and install thor's CWM all in one The package - "AcerA200 SimpleTool V2" worked perfect and in the archive I found, among other files specifically for the A200 was: adb.exe, AdbWinApi.dll, AdbWinUsbApi.dll, and fastboot.exe (You can find those files in many different archives designed for rooting tablets and phones, or in Android SDK. So with those files, a boot image, and recovery image, the SU binary, and memproid, a simple batch file ran in windows unlocked, rooted, etc... The A200 Yay!! :laugh: So I am thinking that maybe I can use a similar scenario to get things moving on my A500 when I get it back. The commands in the batch file were really basic for the unlocking of the bootloader. I plan to try them out on my A500 as soon as possible, the commands in sequence are as follows, in the folder where the windows executable adb.exe and fastboot.exe, and the dll's are located, open a command prompt windows (cmd.exe) and then:
adb wait-for-device
adb reboot-bootloader
fastboot oem unlock
-
"At this point you have to follow the on screen directions on the tablet and use the volume button to choose the unlock option on the tablet", then back to the PC command prompt for the final command
-
fastboot reboot
Thats it!!
If it works like it did on the A200 the A500 bootloader should be unlocked, nothing like simplicity, and a command prompt :laugh:
If it does work now CWM can be installed, and work, giving rise to custom ROMS, and any other customizations I want to install but need a custom recovery and unlocked bootloader to have .
I really hope it does work the same on the A500 as it did on the A200. As far as I can tell there was no special files or images loaded onto the tablet to unlock the bootloader, just adb and fastboot, and apparently there is a built in option to unlock the stock ICS bootloader. To bad I wont find out until next week Tuesday night after work if it does work on my A500.
As always, I will post the results I get right away, so that anyone else stuck trying to get past the locked bootloader, can, well if it works, and if it does not, well at least I tried. So far I have tried all the step by steps with no luck that I can find, and as I have seen others experience the same thing the tablet just plain refusing to except any flash using APXFlash or AfterOTA in attempt to unlock the bootloader, wish me luck, and if anyone else happens to try this before I can in a week let us know, or if you already have a solution please let us know. Thanks so much
And again thanks everyone for all your time and contributions, the guides, tutorials, and custom software that you have written and shared, and for sharing with us your own trials and results so that we can all enjoy the most of our devices, the way that we want them to be I am fairly new to Android mods and development, but I have always liked the Linux based OS, and infiltrating exploits on gaming consoles, phones, etc.. has always been a sort of pass time hobby of mine, when time, money, and devices to play with are available to me I am definitely glad that I found and joined this forum, by far the most helpful, and extensive concerning Android Devices by far.

hey thats the exact same thing that happened to me...nvflash hung and same with blackthund3r's flashing tool thing
so what i did was use babsector
here's the link to Heres the link to babsector.rar
How to use babsector -
Turn your tab off and put it in apx mode manually. Press and hold reset button, hold power for 3 secs after the light comes on and release it, after another second release the reset button. Your screen is black and the power light is on.
Download and extract the .rar to a folder on your PC
Connect your tab to your PC
Navigate to the babsector folder and click on 501 A.bat
Reboot into recovery
Go to Mounts and Storage and Format System twice and Power Off
Go back into apx mode and run 501 B.bat
Reboot into recovery and do the wipes and flash your rom
Reboot!!!

if u want to take a look
but all u need to do is follow the instructions for babsector and you're done!
Thank You
Thank You so much this was exactly the information I was in need of. Thank you very much again. I should be able to resolve everything and get on with my custom rom. I am thinking of going with this one: CM10 JellyBean 4.1.2 build for Acer Iconia A500 (picasso), build 3. Has anyone been using this one on their A500 have anything to say? As far as I can tell by what I have read on the custom roms out there it seems to be the best there is for the A500. What ios the best Kernel to use with the CM10? I was thinking of going with this one: godmachine81 A500 Kernel, or The Onyx Kernel Kryos Version 1.5 SR. does any one have anything on either of those, which is the best in combination with the CM10 ROM, or is there a better kernel?
Any how I am excited, thanks again.
And even though I am excited I will be taking everything nice and slow to start with, step by step and carefully, I will probably try a few different arrangements until I get what I feel is the best performing / looking set up. I am pretty sure about the CM10 rom though I just don't see the stock based roms performing as well as CyanogenMod I would love to check out some benchmarks of anyone's A500 running either CM10 or CM9 with different kernels, including stock, and maybe even other roms too
Well one final time Thanks for everyone's help , guides, tutorials, and software. All of it is truly appreciated here
I look forward to whatever anyone has to say on the roms/kernel combos, and I will post my experiences too.

I just thought I would say thanks to all for helping me I have been happily using CM10-Flex V6 Supercharged ROM with the EZTerry A500 latest kernel Overclocked to 1.5 and a few other mods and the tablet is awesome I really Like JB 4.1.2 I did try out CM 10.1 JB 4.2.2 and had to figure out that you need to click about tablet then tap Build in the info 10 times to unlock developer options so you can tick USB debugging but in the end I went back to CM10. My tablet just seems to run faster, better, smoother with the setup I have, I will most likely keep on checking out the latest CM builds until I find one I like better, hehe I Do just love to change things I hear that there may be a CM 10.2 build for A500 soon I hope so . Oh and I ended up going with Skrilaxs V9 patched bootloader with a fancy CM logo I put in with the V9 bootloader image tool.
Any way I just wanted to put in my thanks, and let you all know that all is well and good, and I will keep on testing ROMS on my A500 till I get a new tab and then continue on that one too. I really love the site and all the info, babsector worked great to get things going on the A500 I did modify some of the files to suit my own needs, and install the v9 bootloader and my own choice of CWM (I used thors 1.8)
So thanks tpo all and if anyone has any news they think I would like to hear on the Acer tabs please let me know. I do have an update.zip that will return the tab to full stock, unpatch the bootloader, and stock recovery too incase I ever need to send it in to acer, and an almost stock rom too deodexed rooted, and tweaked, also will install an unpatched bootloader, and stock recovery, I think it would pass for stock "like" and some other nifty roms and tweaks for the a500.
Any how it is late I am ramlbling, lol, long day at work. But as always test tweak, and tune EVERYTHING must be modded, hehehehe
See ya - Kaiji
Hello guys.
I would like to ask you for help with my bricked Homecare. I apparently cocked up the flashing process and now I don't know, how to proceed.
What I did:
At first I used the Russian (translated) version of supertool designated for Homecare Note 7. But the process wasn't 100 % successful. The bootloader has been unlocked, CWM recovery has been flashed, ROM 4.3 has been flashed. The tablet was able to boot, but it always froze after a few minutes of operation. Most probably there was a wrong boot flashed. No idea.
So, I checked the forums and RootJnky's videos and decided to use CWM to flash a deodex 4.3 stock ROM.
Flash process was successful, but after restart the tablet remains in boot-loop.
Now, I was NEVER able to enter the Recovery or Bootloader using the button combination. Don't ask me why, but it wasn't possible. I could however access recovery or bootloader using ADB.
Right now the only status except a boot-loop is the APX mode. Is there still a chance how to unbrick the tablet???
Thanks for any advice.

At worse case scenario you need to use APX mode to reflash. You can get the download references for the APX files, particularly the package from Advent UK. The package is setup for Windows but it's easy to use in Linux with their executables.
The APX mode does reflash your tablet in whole, but the end result may not be perfect, but should allow a stepping stone to fastboot mode.
If you can obtain 'fastboot' mode then your can reflash partitions. The 'adb' mode in recovery level or system level will allow for updates with 'sideload' command.
Hope that helps.

@e8hfff I managed to sort him out yesterday using the APX method the use has now got it working, with no issues at all (WiFi works as well).
The only thing different for him is that his Generic bootanimation which Xolo Tegra Note 7's have is now showing advent.
I will send you a PM in a bit out the bootanimation as i have a idea LOL.

Hi hacktrix2006.
Thanks for the help again. The tablet is working like dream. All my Chinese colleagues are staring at it. The poor guys know only the products of the fruit company (Apple).
I saw the boot animation is a set of pictures in the flash package from Advent. It is ZIPed.
Is there any way how to make and flash a boot animation without reflashing the whole thing? (I know the answer already, but I don't know how to do it DD)

The bootanimation.zip is in /lbh partition under media. Should be a easy enough to copy and paste in if not then i will have a look for a way of doing it without flashing all of it again.
Docs on Homecare Fly One rom update
Hi jardam.cz AND hacktrix2006
I see you guys have a working method to update the Homecare Fly One - do you have any documentation on how to root and update the rom for this model? Jardam mentioned a Russian rom, but it caused problems. I really don't want to brick this, as I live and breathe with this tablet every day! But I can't stand the limitations of no root.
Almost all the YouTube videos show EVGA solutions, and lots of people have Homecare Fly One problems - what's the solution please?
They are all the same base nvidia model which is p1640 the lbh partition is wrote when flashing via apx mode which can be risky. However there is a twrp recovery for our device and a stock 4.4.2 image from tom you can use to flash a generic version if the os.
hi all and thanks for your help in advance...
i have been assigned an a500 which is bricked and only shows the acer logo and nothing goes on from there
i have tried multiple roms along with custom roms as an update.zip into an SD card but it stops at the same position which is about 30% everytime on every rom
ive tried fastboot, says the BL is locked and when i tell it to unlock it it just says OKAY and stays locked
now blackthund3r with his apx flashing tool presented some hope as it detected the apx mode but after the flashing starts it wont go into bootloader mode the screen is just black
i have attached a screenshot of my pc trying to identify the tablet with apx not installed for no driver is found
i have installed every driver i can put my hands on starting with the latest from Acer drivers and none of them seems to give me the apx driver.
i think the only problem i have is the apx driver, can anyone point me in the right direction? ive got my SBK from afterota only one time and it never worked after that time. can anyone help with the drivers?
#edit:
i forgot to mention that even though it says apx is not installed, when i connect it in apx mode i have a little usb icon which says "eject APX" call me crazy but that just says apx IS installed right?

Generally, the APX (boot recovery download) driver should be installed with just the normal Acer drivers from the web site. On a Win8 pc, it can be a real pain, so if you have a Win7 pc, I would advise it. I suppose you are looking in Windows "Device Manager"?
Not sure about the "eject APX" message. Sounds strange to me, but maybe it says that on an XP PC, been to long to remember.
Stock Acer bootloader has no "Fastboot" capability. This was added after ICS with a patched bootloader.
Either way, you will need your CPUID number to use any of the NVFlash tools. There are stickies on how to get this, but more than likely you will need a Linux set-up, not sure if there's a windows method.
If the tab had been rooted, and a custom recovery added, there's a possibility there was a backup done, and it would be in the Clockwork Mod folder on externalSD card.

I am running win7 x64 and the apx drivers seem to be installed as blackthund3r recognizes it, its just that in blackthund3r apx tool it never seems to want to get into the bootloader mode i have no idea why.
also regarding my CPUID when i used afterota it showed me :
Tablet Serial : 485FEFA483118011
Tablet Cpuid : EMULATOR-5554
Tablet Sbk : 0xF5030000 0x00000000 0xF0D1E302 0xF0D1E302
Android Build : GT-N7000-user
Bootloader : 0.03.01-HC
now isnt the CPUID a 15-16 digit hex number?
and if my CPUID is wrong in this case above it should mean my SBK is wrong aswell right?
the build number is of a galaxy Note device which is also strange.
also, the device came with no SD card and it has not been rooted or a custom recovery installed on it, the owner says "it just died"
I had the Linux idea in mind as a last resort i suppose its time.
thank you for your help

Oh man, Somebody must have tried installing a Galaxy Note Rom? Got me a little confused on just exactly what you have there mate.
The CPUID as you stated, should be an alpha numeric sequence such as for example (mine)038061c7409fa617.
Why it's telling you it's Emulator-5554 is quite strange. Tell me, how exactly did you get this CPUID? As if the tablet won't boot past the bootloader (Acer screen), then the usual discovery tools we have, can't get it, and this I can promise. I'm guessing it's just spitting out some programming error.
And, I can also say your SBK number is suspect also. Looks weird. Here is mine (no, won't work on yours) 0x79531F00 0xBB680C01 0xFB22E803 0x8ADE2003
I would suggest the following;
There's a user here, dibb_nz, and he has some links on unbricking. Currently he is abroad, so won't answer PM. Also, there is a thread "Why CPUID is Important (might be the same things). In there, are some steps on how to get the number from a dead tablet. No, I've never personally had to do this, but other folks have. I know there's steps from Linux, but believe there may also be windows steps as well.
Another good link from Linux (you can run I dual boot, as I do) http://forum.xda-developers.com/showthread.php?t=1751978 This should be easy to follow, and probably best chance at getting it.
Another good thread from Dibb_nz http://forum.xda-developers.com/showthread.php?t=2049778 Has several unbrick procedures.
I have several factory Roms here on my server. I try getting one whenever I come across them. Acer in all of their infinate wisdom, have shut down their OTA servers for quite some time, and also, they add and delete factory Roms from their official support site all the time.
If I can help you, I will. Some things may be out of my control, but will help as much as possible. We have some pretty good folks here in the 500 forums, but the tablet is getting a bit old, and most have moved on to somehing newer.

In there, are some steps on how to get the number from a dead tablet. No, I've never personally had to do this, but other folks have. I know there's steps from Linux, but believe there may also be windows steps as well.
Another good link from Linux (you can run I dual boot, as I do) http://forum.xda-developers.com/showthread.php?t=1751978 This should be easy to follow, and probably best chance at getting it.
Another good thread from Dibb_nz http://forum.xda-developers.com/showthread.php?t=2049778 Has several unbrick procedures.
I have several factory Roms here on my server. I try getting one whenever I come across them. Acer in all of their infinate wisdom, have shut down their OTA servers for quite some time, and also, they add and delete factory Roms from their official support site all the time.
If I can help you, I will. Some things may be out of my control, but will help as much as possible. We have some pretty good folks here in the 500 forums, but the tablet is getting a bit old, and most have moved on to somehing newer.

I got my CPUID from afterota "no idea how but it just worked for one time, and later yesterday worked again".
when i try "adb devices" it just shows nothing, while yesterday also i tried the same command and it returned with EMULATOR-5554 as a device connected and i could get in the shell but could do nothing from there...
i have seen those posts before they have been helpful but as far as using "a500 manager tool" to recover my CPUID, the tool hasent worked.
anyways i suspect the only way of getting my CPUID is through a linux distribution,and from there i can stumble around with nvflash from there or go back to windows. As I dont have any linux expertise it would be a good experience.

Use Ubuntu for the linux distro. It's by far the most common. Basically you can install it 2 ways.
1) As a dual boot (might have to disable a BIOS setting if your PC is pretty new. Usually only if it was a Win8 new system) Benefit is that the Linux OS will get 100% system resources. Downside is that it'll partition your HDD.
2) Run it under cygwin. Basically an emulator which runs within windows, and you create a virtual drive for the Linux install. The benefit is that you can uninstall it rather easily when finished. Downside is it shares Windows resources.
If you're only after the UID, then probably the cygwin method is better for you.

i've never heard of cygwin, i was thinking virtual machine but i was slacking due to the work it needs doing and my impatience... i must ask if afterota is showing EMULATOR-5554 and i managed to get it in adb mode and it still showed EMULATOR-5554 do you think its even recoverable in ubuntu?

Well, being in the 500 forums, and owning a 501, I can say these tablets are pretty much bulletproof. I've never known one that can't be unbricked. Basically, if it has some life, it can be brought back. Mine blew away the bootloader, hard bricked. Took out the mainboard, slapped it in the oven, reseated some nand chips, and it updated the blob file when I booted it. :good: imagine that!
It's still a little flakey running EUUS files, but it's on 3.2.1 and rooted, so I will leave it on that rather than press the issue any further. Besides, it's only used for You Tube and Browser anyhow.
I would say the Linux method will probably reveal the true CPUID. Afterota seems like it's generating some development code. Like I said, none of those tools will work properly unless the tablet OS is running, so who knows what strange things will happen.
I've never used VM, but it should also boot ubuntu.
This chap just got his CPUID today using a Linux distro.

the oven? im confused what reflowing the solder has to do with anything lol and i hope im not going to that stage haha
im downloading ubuntu now as we speak, im hoping it will work but im confused about the libraries that i need to download, GCC and the other ones, are they something special and special installation required? or sniffing around google would do the trick?

Well, normally after you get an ubuntu install, you can download extra packages. Terminal for one. I'm sure the Ubuntu help center tells you how to get certain packages (lib's and such). Basically you do it via a terminal window. Like I said, I've never used that particular procedure myself, but seems some others got it figured out.
Ha Ha... the oven. Yes, I was skeptical to say the least, but thinking back on rice to dry out a phone, putting a dead HDD in the freezer, well, it seemed plausible. And for me, the oven trick worked. Pressed all the nands back into place, and was able to clear the "Blob update failed" error (was stuck with no working bootloader, hence a hard brick). I attribute it to my 2.5yrs old girl dropping the tab once too often (although was in a good cover).

Eh, ok, you got the CPUID. Hang on and I'll give you a link for Timmy Deans 3.2.1 rollback.... Sounds like you got a corrupt partition.
OK, download and unzip the contents.
http://www.mediafire.com/download/fo4wqjeald4s3rj/tdv4_rollback_rom.7z
Now, in the contents, you will see the file pbj20upgrage.exe
Run it as "administrator" (right mouse click it and select run as administrator)
Now, don't plug in the tab. After it does a couple things, (installs drivers, starts looking for current build it will eventually prompt you to start your tab in APX mode. Do it. Then connect, enter your CPUID when asked, and it will NVFlash a complete pre-rooted 3.2.1 with CWM Recovery.

Great!
Now, just remember, when you install one of the full ICS Update files (I have a thread stickied in one of these forums), it will change the bootloader, and also do away with the CWM custom recovery. A custom ICS ROM will not run on an HC 3.2.1 bootloader. This is why we had the Blackthunder tool and patched V8 bootloader. Just so you are aware.
Good luck!

blackthunder's tool just WILL NOT RUN on the tab its always stuck on nvflash resume mode, and uploading image, even after i got the tab back to life i have no idea why, and everytime i try to flash the v8 or even v9 BL it just freezes and i get the acer splash screen again, and then i have to rollback again.
is there any detailed tut on installing ics with the correct steps ? it would be much appreciated, HC wont run any recent app and its ticking me

Welcome to the world of corrupted nand memory.
You can try running "babsector" and see if it will NVFLASH repaired partitions.

Not saying it will fix it, but it might.

Please Help,
Two days ago my A500 freezes!
Had to force a shutdown, at start got stuck on Acer logo!
Tried the 4 official updates everyone talked about with no luck!
The only one that solved my problem was the original 3.x Honeycomb ROM:
SD_Acer_A501_Android 3.2.1_4.066.29_COM_GEN1
That Solved!
Then I downloaded a suposed Acer A500 Stock Rom to update from 3.2 to 4.0.3. Didn't notice was a rooted one, update completed then got an error.
ROM used: Acer_A500_Stock_ROM_v1.054.00_ww_gen1_rooted_4.0.3 _ICS
Now I can not even load stock recovery (vol-+ power), only power light turns on and off as i press power. No vibrate, no acer logo only a black screen!!
Can anyone help? Ideias?
PS: The A500 always was stock, no root, no special recevory, etc.
Thanks,
PereiraMan.
update
:fingers-crossed:
For the record it seams that my A500 is in APX mode.
After using a fresh install of Windows 7 with th Acer drivers, the fantastic OTA Tool: http://forum.xda-developers.com/showthread.php?t=1675939
Detected my A500 as in APX mode, and has an advanced feature specific for those like I stuck on APX mode that let's us Install Bootloader and Recovery.
First try didn't work: I downloaded and tried to install TWRP recovery and ICS Bootloader, it was stuck on FASE 2 (flashing recovery).
Will try this night with A500_Thor_Recovery_1.7.3.a500apx. :fingers-crossed:
Thanks,
PereiraMan.
No luck yet
Not giving up... no yet!
On the Windows Device Manager it detects tha A500 like "Acer USB Boot-recovery Driver"
The other night a think it was different, something like APX...
Any way in the system tray on the USB devices always shows APX device.
APX Tool and OTA Tool detect the A500 in APX mode, but none of them can flash a recovery... Windows Drivers issue?
Because ADB via command prompt doesn't detect the device!
The tools use ADB commands, right? And ADB shoud detect the device in APX mode, right?
Any APX expert?
More info:
in the driver details I have this values: "USB\VID_0955&PID_7820\5&24FD8A70&0&1"
Read somewhere the last digits are the CPUID... calculated the SBK. Hope is correct.
Thanks,
PereiraMan.
ok, first of all we need the patched bootloader to be able to flash a recovery and a custom ICS+ Rom. But to do that, you need to root first, using the ICSRoot tool, see the root guide in my sig for the download.
Then while you are there download the babsector.rar file - this file will install the patched bootloader and a recovery, but more importantly it will output an error if your tab is one of those which has a faulty memory chip. If this is the case then nothing you do will fix this issue
Put your tab into APX mode(do not use otatool or a500 manager to do this for you, you need to do it manually via the buttons) click the a.bat file and follow the onscreen instructions.
IF the bat file runs without error...congratulations, you now have the patched bootloader and recovery. But what you do not have yet is a workable rom...You must now boot DIRECTLY TO RECOVERY (PWR VOL DOWN).
The patched bootloader does not work with HC Roms which is what you still have at the moment, even tho you tried flashing ICS previously. So, flash one of the custom ICS+ roms.
The best thing to do though is wipe all your userdata first before you flash the rom. You can try and get away without the wipe but its not best practice!!!!
Once the rom is flashed you can reboot.
Just a couple of things to note - the a500 is very old now, and so are alot of the roms. You may still have trouble, altho you will have a running system, it may not run as you might want!!! I have not used my tab for this very reason...it freezes or takes along time to do anything like surf the net, emails etx...even using it as a media player seems to be too much for it,lol - I have not tried any of the JB roms, the tab is still on one of the "Flex" series of roms.
But anyway good luck with everything, feel free to ask if you have any issues

Thanks dibb,
I will try to root, but don't I need the CPUID/UID for that? Everyone tells me that without it I can do nothing...
I'm stuck in APX (my A500 only turns on in apx I have nothing else) and have no CPUID... (i'm installing a Linux right know on a secondary laptop to solve that issue)
Also ICSroot link is not working!
About the A500, I bought it almost 4 years ago it had already ICS update available OTA that I apply in the first day... True it's a litle slow now when loaded with apps... A couple days ago when recovered from the "acer logo" symptom with acer recovery and honeycomb ROM I was susprise how fast it was (and yes without any apps). I was thinking about a light costum ROM or Cyanogen UnOfficial stable (version 10 i think) when i recover it.... Hope so! :fingers-crossed:

YES YOU DO NEED CPUD!! Sorry, did not realise you did not have that. NONE of the auto tools will work without'!-This changes everything.
You are limited to a couple of choices to retrieve your UID
Hope your PC has stored it by you previously having Tabconnected to Pc via USB- there's a tool in my CPUIDGuide,1 forget nowwhat it is called.EDIT: USBdeview
OR
installing Linux.
I am pressed for time right at this minute will await
your reply as to this development
dibb
Success!!!
Finally Got my uid via Linux, was hard to install Linux, all my old CD's where broken, had to create a usb pen!
Anyway, my A500 UID: 0x37001474420a157
But that 17 digits, so realized the leading 0x is not part of the UID!
Flashed Bundle 17 with APX Flash Utility!
Now going to try some ROMs...

I got this from work and I'm not sure it's worth fixing but here is where I am with it. Recovery mode just shows the dead Android. I can get into APX mode but that's it. I have the SBK number and Blackthund3r APX Flash tool and I believe the recovery is what I need to flash. It seems all of the links to APX recovery files are broken. Please help me with the files I need to unbrick this thing. I believe if I can get into recovery, I'll be OK. Let me know if I need anything else.
