Hi guys i know Brian117 originally posted this and sc2k helped him fix hes tablet i apologize for not continuing the thread
but its been almost 8 hours since i bricked my tablet. i can't take it anymore i tried alot of things i search Google for answers until i gave up.
Im not a pro but im not new to flashing roms so i originally installed CWM from the "it's Magic" post from sc2k i did it successfully then installed
Dexter's primee rom successfully aswell no problem. Once i discover Virtous picasso rom, Honey Villain rom i decided to test them out aswell
see witch one fit my liking so i did successfully. After seeing Virtous galaxy i decided to check it out i did i got an error at boot so after posting
my error some suggested i update my CWM so i was able to boot into galaxy rom loved it then i downloaded "update-recovery-thor2002ro-rev1.3.4"
from the instruction i gathered im suppose to just flash it through CWM so i did and it said that i succesfully flashed it now reboot into CWM to see
the changes so at this point i thought heck yeah!! then to my surprise i reboot it the tablet and was greeted to " secure boot: image SOS checksum fail!" so i then tried a normal reboot the ACER logo just stood there hanging looking back at me laughing.
Before i originally installed CWM i followed all instruction so i have all my back ups and UID saved on my PC. i Already pm sc2k about see if he can help me
but i thought i post the whole processed of what i did to avoid others bricking their tablet aswell and hopefully in the mean time if any of you guys have any suggestions, tips i gladly welcome them since i cant return it to staples anymore i have to deal with Acer if i cant get it to work. Also I fully understand this is a risk i took and not blaming no one for my error all im asking is for help
u done one wrong step, u didnt run its magic before installing thor recovery i think..
I am pretty sure that thor explains in his thread that you should flash his "update-recovery-thor2002ro-rev1.*.*" files only if you allready have his version of recovery installed.
So you should have installed the full "recovery-thor2002ro-rev1.3.4.rar" as described in 1st post of his thread and not just try to flash the update-recovery file.
Maybe thor or sc2k can help you now..
I think the problem was that your original cwm was an older version that did not run itsmagic automatically on startup and the update package doesn't run it either. I'm so glad to see someone who has backups!
Don't know if this will help.. The hang at the logo is usually an indication of needing to do a data wipe after installing a custom rom. Was the tablet booting normally before flashing the cwm update?
Anyway, this thread from sc2k demonstrates a method to wipe data. You can see if that will help get you past the logo screen. If it does, great.. run itsmagic, then you should be able to get back into recovery.
If it doesn't help, you'll need to ask sc2k how to unbrick via nvflash (that's what mcblk0_start file is for).
Edit: aw man..I just realized I forgot the link.... ah well
Update: with help from sc2k i was able to fix my tablet it worked great.
and im currently installing a custom rom through Thor2002ro CWM.
Thousand thank you's to sc2k and everyone in the Development comunity
for the advice i knew if you guys couldnt help me no one could.
thank god for the XDA forums.

How do I PM SC2K. I have the same issue with my a500. LNX Checksum error. I Need Help!!! Please Help.
I was trying to flash my A500 back to stock and something, somewhere, went horribly wrong.
I did everything I normally would: factory reset, wiped cash and dalvik, and then flashed the ICS stock zip. I rebooted the tablet and it said something about updating the bootloader and then went black. Now, the black screen is all I can get.
I've got good drivers on my Win8 computer, and the device is recognized in APX mode, but I haven't been able to do anything with it. I've tried messing around with A500Manager, AfterOTA, and the APX Flash Tool, but I do NOT know my CPUID - which makes everything quite difficult.
I looked through the thread about getting the CPUID from the tablet via USB while in APX mode, but I know nothing about coding or building drivers and the like, and it all went well over my head.
I don't normally ask for help like this, (as one could guess from my post count) as I very rarely find myself in a situation a good amount of reading won't get me out of. This one has me well and stuck though! Any help would be greatly appreciated!
(For the record, I was on the unlocked V8 bootloader, Thor's CWM, and CM10 and tried flashing Acer_A500_1.041.00_WW_CUS1)

Hi Clark, sorry to hear of yr troubles....there's a recent thread here that sort of describes your issue....I'll post a link in a tick
But what happens when u turn the tab off - make sure pwr led lite is off - and then power on again?
Can u charge yr tab - pwr led is orange?
Flashing stock - did u use an update.zip or EUU or flash via cwm - there's a great guide how to revert to stock the easy way by jdgM3NT4L u should look at.
You might try booting to fast boot pwr volume UP but it sounds like that may not be available as u said yr tab did say updating boot loader...
Once u have the v8 boot loader the ONLY way to revert to stock is a downgrade to HC
Try running the nvFlash manually see civatos boot loader guide, (this requires yr tab to be in apx mode first,) and run the bat file.
IF YR TAB DOES NOT ENTER BOOTLOADER/A500 APX MODE please disconnect everything and don't go any further - you'll end up in more strife!!!
I'm on my way to work so will post links when I get there....

Thanks for the response!
I flashed a .zip via CWM to attempt to revert to stock. I flashed an ICS stock ROM (Acer_A500_1.041.00_WW_CUS1), while on the V8 bootloader, might that have caused my problem?
Right now I can only get the tab to do two things: charge and boot into APX mode. No matter what else I do I just end up in a black-screen APX mode. Power+Vol does not do anything other than put me back in a black screen with power LED white state.
I haven't tried doing an nvFlash yet - can I do that without my CPUID?

most definitely....u must flash a stock update.zip....but an EUU is best
u cannot flash ANY ics rom like this UNLESS u have the unlocked bootloader first... and u must downgrade If wanting to revert to stock....

just becoz i wish to spend some quality time here on xda....we are flat.out at work, lol....
u can try theauto flash tools.but. they
rely on the cpuid....there's a guide.in my sig but the.only option u have is eppeP.s method, check.out srbeens guide there..

If your tab has been connected to your pc, you can get the cpuid from your pc, without the tab connected. (using USBDeview)

Well,there is still Linux. Not a Linux guy, but search the forums, you can find instructions for running some linux commands that will find your cpuid. http://forum.xda-developers.com/showthread.php?t=1751978 is a good place to start.

Fantastic! I've got a laptop running Ubuntu and I'm pretty comfortable with being a script-monkey in terminal, I'll give it a whirl when I get the chance to spend some quality time with the tab.
Thanks for the link too, I had not found that one before. I had seen eppeP's guide and it made my head spin pretty quick, the srbeen one you linked to looks like someone with no dev experience like myself might be able to pull it off.
*fingers crossed*

HAAAA!!!! Success!
Well, I had some trouble with my linux laptop being 32-bit and spitting out the wrong UID, but got that sorted and snagged my UID and SBK.
Used blackthund3r's APX Flash Tool to get the V8 bootloader and Thor's CWM back, and then flashed rooted stock - all is good!
Not sure if I'll try getting back to full stock or not, still deciding if I want to sell the tab or give it away as a Christmas present.
Thanks so much for the help everyone!

that's gr8 m8.....u feel like writing up a bit of a 'how to' on wot u did, would come in mighty handy for others in the same boat?

I could, but I'd be pretty much just replicating srbeen's thread here: http://forum.xda-developers.com/showthread.php?t=1751978
The only thing I could really note is that eppeP's code that's linked to in srbeen's OP will only work on a 64-bit install of Linux. If you're running a 32-bit system (like I was) you need to scroll a bit further down the 1st page and grab the proper code for a 32-bit script.

while trying to root and unlock bootloader on acer a500, somehow i screwed things up and had to finally flash a euu file to get it working again, now im rooted unlocked, i guess, im able to flash roms but my storage has been reduced to 128mb. , no matter what i flash or try no change, not enuff room to restore any apps.. question is any chance or anything i can do to recover that space? thank you...

Wow, you might have screwed the pooh on this one.
Did you install the V8 or 9 Unlocked bootloader?
Ok, for starters, WHICH EUU and what is current operating system?
Did you flash a custom Recovery (in this case CWM)? If so, what version?
But BEFORE you do anything else, you should get your UID number from Civato's sticky thread or one of the others. Very important. So check the sticky threads, there's a simple app to get your UID. Save it somewhere in like Notepad.
Then report back.
ok let me say ive been rooting my ohones since the OG droid, its been 5 or 6 diff since then but this tablet has me stumped... can you please tell me how i can find which version bootloader? the euu file i got off of tegra forum owners, ive got cwm based recovery v5.5.0.x 9thor2002ro rev 1.7) and as far as operating system ive flashed 3 diff roms so far the 1 im on now is flex resurection rev1...4.0.4 android version, ive tried 4.0.3, and jb... i have cpuid if thats the same as uid#...? if you could help in any way its much appreciated...

Ha ha, no mate. No doubt you are a bit familiar. Phones is different than tabs though.
Ok,, when you start your tab normally, you should see the bootloader version. Upper left corner.
There's only a couple EUU files, and I believe both are Honeycomb.
CWM ver is ok.
But if you are running ICS or JB roms, on a HC bootloader, than that's not OK.
So, I need current ROM and version, and current bootloader version. Civato has several roms.
Just wanna see where exactly you are at right now.

3.11 sounds like an HC bootloader, or one of Skrilax_cz's initial bootloader. If you try running ICS or JB based roms, you're gonna get a lot of screwy stuff going on, Like display glitches and stuff.
You need to goto Civato's Bootloader thread in the Dev forum, and try running the apps listed there to get you to Skirlax_cz's unlocked bootloader for ICS. Works for CM JB.
@dibb_nz also has a thread there, explaining things about UID and stuff.
Then, after you get the unlocked bootloader NV flashed, throw CWM on there. I use 1.7.3 I believe. In mounts and storage, there is an option to format your internal SD. Select the option, then do your wipes and formats. Then flash the rom.
Think you'll be okay then.
recovery also says thor kernal v1.16mini running itsmagic that is on the screen when i run a backup....

It's magic is no longer needed for unlocked bootloader and ICS/JB.
If you boot holding PWR and Vol -, you should boot into the V8 bootloader menu. If you don't, there's an issue.
ok i got that set up right now, its magic is no longer needed it says... everything is working fine but still only 128 mb of storage wiped mounted unmounted formatted everything, nothing is changing it....

Well, sounds like the emmc memory is hosed. As you read in the threads, it happens sometimes.
However, as a last chance, there is a thing called "bab sector". I've never used it before. Supposedly helps recover bad memory blocks. I've tried searching for it here in the forums, but must not be using the right search parameters . Found discussions on it in @Skrilax_CZ bootloader thread. It's labeled for the a501 but doesn't matter as partitions are the same I believe. He knows more about the memory partitions, so may want to post the issue in his bootloader thread.
But, I do happen to have one of the zips on my Dev Host server.
http://d-h.st/iQX
If I remember correctly, there are 2 variants of this repair file. @dibb_nz might know more about it.
Also on my server. is an HC roll back tool. If not mistaken, it may have a different variant of EUU. Might wanna run it and see if it resets partitions. As it seems like things screwed up when you ran an EUU.
http://d-h.st/0x7
At any case, I would run the EUU again. Can't hurt, and maybe will reset partitions.
thank you that bab sector file how would i go about installing that? flash with the a500 apx flash tool ? and the euu i believe get done that way also?

Ok, never run the Bab tool before. But looking at it, you have to be in APX mode just as you would to run NVFlash, as it operates the same way.
With the Bab tool, if it errors out writing any of the partitions, it should at least generate an error message. Now, you'll have to search to find out how to manually get into APX mode. But if I'm not mistaken, it's tab off. Hold PWR and Reset button. Then count to 3 or 5, release reset, then 2 counts later release PWR. But please do not quote me on this. Been some time, and primarily I work on the A701 now. But it's pretty close.
Then, run the bat file in the zip via a command window. Note I have never had to use this before.
The rollback/EUU works just like any other EUU. Has an exe file in it to run (make sure USB debugging is on, and remember to get your UID.
I also have an ATT EUU handy. Not sure which version it installs, but will be HC.
I still say to post a note in the Bootloader thread. Skrilax_cz knows more about the 50x partitions than even Acer.
flashed the bab file thru cmd promots device said pass reboot... rebooted to booloade mode saying error invalid primary lnx kernal image.. wont d...o anything but reboot to this same screen... also the other file euu is a rar file wont let me do anything with it when i flashed the other file euu i used the a500 tool and it found the euu file, how do i extract the euu from the roll back rom?

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.

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

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

Looking to do a stock install of 3.2 on A501
blackthund3r said:
LIST OF FILES
Please note that none of these files are rooted and/or tweaked! They are stock Android ROMs from Acer and designed for stock recovery!
Flashing them will remove custom recovery and/or custom bootloader! You will be fully stock! Update zips may not install if you have modified your device in any way. If unsure use a full package! You need an EUU package only if your device is bricked as it will be completely wiped clean in the process!
-----------------------------
I am looking for the 3G version the 3.2 stock ROM to do a fresh install on my A501
The link from Vache seems dead.. can anyone please help to provide that particular ROM?
Thanks a lot. Desperately need some help as I'm password locked out!

Best to just get stock ICS. Why are you password locked? Is the device stolen? I can easily help you get past it but I'm not sure whether I should.

Thanks blackthunder. It's our personal device, my wife set the password some time back and is sure she hasn't forgotten but for some reason it's not being accepted. We can't figure out why! I have the original receipt and box etc in case anyone's interested!
I tried the stock ICS Rom by naming it update.zip and rebooting into recovery, but that gets stuck at the Android guy logo immediately. Also tried 3.2 before that via a link from this page, and that seems to work until the progress bar hits about 80%. Then it just reboots back to the dreaded locked screen. From what I understand I can only do a reinstall of the same ROM version that's currently installed? We have a password lock on it, and not pattern. Would highly appreciate any help. . Really want this thing to start working again. It's practically new [emoji20]
Guys any idea? Really desperate here. Thanks in advance!!

Your beat bet is using an EUUs package to wipe the tablet and reset back to 3.0.1 then use Flash Tool to get CWM or TWRP + a decent ROM

To install EUUs, is it the same process; rebooting with power+volume and flashing via SD card? What version EUUs do you think I need, currently I have 3.2 installed. Is there a guide for above?... will be a lot of help. Many thanks

Actually, even easier.....use the APX Flash Tool to get yourself a CWM Image (you'll need your SBK....there's a fair few guides on obtaining this) then do a wipe data/factory reset within CWM.
From there it's fairly easy to side load the latest Acer ROM.
Thanks. I'll try it out over the weekend! Appreciate your help!
God morning! For the apx tool, I'm not sure if USB debugging option is selected, never ticked that myself consciously. Is it OK to go ahead?
Tried using the apx tool after downloading the Acer USB drivers and in short no luck.
Had to go the manual route for flashing since I don't have USB debugging enabled.
Tried two packages, one honeycomb bundle 6 and then also tried a later one for ICS.
It goes thru the motions enters APX mode with confirmation as well on the tab screen, without any hiccups right to the end. But then reboots to the old dastardly lock screen asking for password!
Any ideas? Already backed up using mobo app so am OK to wipe clean and start anew.

Options for upgrading an Acer A500: Acer_A500_4.010.15_COM_GEN1
OK, heres a totally noob question. I have an Acer A500 I bought used. It has been rooted apparently. Has the ClockWorkMod bootloader installed, v5.0.
My question is, what are my options to upgrade this tablet and is there a thread with instructions on which firmware files to use, how far can I go with upgrading the A500 (ICS?). Not really looking to trick it out and go the whole mod route, would be happy with stock firmware, just looking to make it a little more up to date and, above all _stable_! The main issue I have with it now is the wifi craps out every month or so and I have to do a refresh and wipe all info and start over.
I used to get prompted to install a system update, and every time, it would fail with the dead Android dude on his back....so sad. Now, it just tells me, "Network Coverage is poor, please move to a location with better coverage". I am sitting right beside my router...
Here are the relevant specs:
Model number: A500
Build number: Acer_A500_4.010.15_COM_GEN1
Kernel version: 2.6.36.3
If you need any other info in order to help, just let me know.
Thank you very much in advance for any advice!!
