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
rgds dibb
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:
Thanks,

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...
Thanks dibb!

CyanogenMod
Hi dibb!
Just for the record ended up with cyanogen 12 tegraowners ROM (android 5.0.2)!
And did a litle CPU overclock with Thor Recevory from 1ghz to 1.2ghz..
I'm now a happy user of a Acer A500 with 4 years and a new life!
Thanks,

Okay... so the other day in class I was thumbing through the intrawebs and noticed the leaked ICS had came out for the A500... I tried flashing the ROM to my tablet, thinking it would be a cinch if I just followed the directions. No go, just stuck on Android boot logo. That's fine and all, made a back up with CWM (which i think was my initial problem with the ICS version.. correct if I'm wrong please,) but... my back-ups check sums were mismatching for everything. Couldn't get them to match and couldn't figure it out so I decided to just flash root stock version back on to the tablet and go from there using my titanium backup.
I flashed, and bam... vibrating black screen, no CWM recovery anymore no matter what I do. I've been using the SDK manager / ADB terminal thinger / EUUS Acer Iconia Tab Software Upgrade Utility. I cannot for the life of me find my CPUID, or at least the RIGHT CPUID. I understand to use software to find it but I don't think my tablet is giving the correct info, or something??!?! When I run adb devices in CMD in the platform-tools directory it doesn't list any devices available. If anyone could help it'd be greatly appreciated. Could possibly upload a screenshot of my usb devices with the USBdeview software?

To get your old uid number, look in one of your cwm backup folders on your SD card.should say uid.txt.
Then you can either use the photo tutorial at androidtabletgeeks.com, or there is text instructions here at xda.
Also, sounds like you may need to load the a DB drivers for your tab.
Help ME!!!!!!!!!!!!!
I've got a similar problem. My A500 are with the Boot "Verified Boot failed" and no way I can make it work again. He was with the ICS ROM'm trying to make it back to the Stock ROM but I can not. Please Help Me.
Hmm...

Okay, that got me started in a good direction I feel like. The only problem is that CWM made them all "*.img" files. There is a "system.img", "boot.img", and "recovery.img". Which one should I be trying to tear into to get it? And I'm pretty sure I have the adb drivers installed, or at least my device shows up in my device manager when I put it in APX mode, and I've downloaded the USB recovery drivers from the ACER website, along with other drivers that people have suggested.
Thanks for your quick reply! Hopefully this gets me somewhere, if you have any more suggestions on where to find it within the filesystem / *.img files let me know.
** Also a "data.img"... didn't want to leave the right one out on accident haha.**
Still nothing...
I've been trying to go through the old CWM back up .img files, but the only one I can even open and extract is the system.img which from what I can tell, has nothing to do with the CPUID. Next I started up a virtual ubuntu to try ADB out on there, same results. Even changed the vendor ID to the one given to me by lsusb, still nothing. I'm out of thoughts on this... I'm burnt out on trying to get this to work.
When I opened up usbdeview, I saw an old version of my Acer Iconia tab when it was actually working. Used that serial number and it made it through to where it said it was upgrading, but then sat/hung overnight. didn't move or make any progress so I unplugged it so I could go to class and keep working on it... now that cpuid doesn't work either.
Is my tablet a fancy paperweight now?
A500 Reborn
People,
I managed to make my A500 back to work with an update file, but forum cannot permit to put the link here. Take out the spaces of the link below:
www . fileserve . com / file / 2HUVP9D / update(ok) . zip
Rename the file to "update.zip", then save this on Sdcard and Boot the A500 with Vol - pressed.
Worked for me.
so..

Did you have a recovery that you were able to boot into when you did this? Or does holding vol - while powering up install the update.zip? If you used a recovery manager it's not going to help me at all.

That's where I started this journey to get it working again lol. The only problem I'm having is with finding my CPUID or the UID he talks about. The numbers I get don't work because they're for the recovery driver, not an actual UID for my tablet. There is no serial number displayed when connected.

Well I had... but I think you just helped me out. Will these show up if I'm using the recovery driver to get it to be recognized? I can find it when plugged in under Acer Iconia, but I think that's from a previous plug-in before I flashed it. Now when I plug it in it comes up under "acer picasso recovery driver". I never new what vendor ID to look for, so I'm going to do that.
Do I have to put serial number in the .txt file named cpuid to get it to work?
Thanks for replying and giving me something to do!

Okay, so I'm in my college class so I don't have my own laptop with me, I'm trying this on a "frozen" desktop. I said earlier my tablet show up in usbdeview as acer picasso recovery driver, but it flip flops between that and acer USB-Boot recovery driver. Don't know why. Either way, when I plug my tablet into my computer and put it in APX mode, it shows up, but no serial number or anything. I'm going to try what you said on my laptop at home where I've plugged it in before I flashed it, maybe I can find it then. Hopefully. Here's a USBdeView picture of what I'm seeing when I plug my tablet in.

Our computer labs all use deepfreeze.
Yeah, it should be listed on your laptop if it was plugged in while running honeycomb.
Best of luck.

Hey so do ours. Gotta love the key combination to get past it
But that's awesome, this gives me hope! Will try this if I ever get out of this class... yay for linux classes that last from 8 to 3.
I have also bricked mine due to not reading things before jumping in as usual doh.
I installed the lightspeed ics beta 5 and it was pretty nice but a game I have been playing kept freezing so I decided to go back to 3.2 official by putting it on the sd card and booting recovery. It went through install etc but then just goes to a bootloop with the blue lightspeed flashing adroid. CWM is no more and like an idiot did not get my cpuid prior.
I tried installing the 3.0.1 unstable too but that did not work either. It just sits on flashing android now.
Will I have to wait until an official acer ics update.zip is available once released?
Thanks in advance

I don't think you'd HAVE to wait for the office ICS update. For you, I'd say do what I've been trying to do which is get it back to stock rom and recovery manager so I can wait for the official ICS update. Eventually, if I ever do unbrick this thing, then I will have to decide if I want to wait or not. Or dual-boot ubuntu

I cant get my cpuid though as it dont show in usbdview either unless I need the drivers from sdk first.
Ok here goes. Sorry for the long post but I want to give as much info as possible so I don't leave any of you in the dark about anything. Been working on / researching this for four days now to no avail.
My A500 which was running ICS 4.0.2 just randomly bricked itself one night, so I downloaded EUUs_SBK_Acer_A500_1.016.05_COM_GEN1 from here. It worked, but I really don't want to stay on HC 3.0.1 so I decided to go through the updates. It updated great, HC 3.1...3.2...then when the ICS update came along BAM it bricked itself again (stuck on Acer loading screen)
So, I decided I might as well root it, since I've always wanted to. Ran EUUS again to reset to HC 3.0.1 then ran gingerbreak. Installed Acer Recovery Installer and used Thor's recovery 1.7 I believe it was. Booted into recovery and tried to install update.zip from the STOCK Acer_A500_7.014.16_041.206.01_COM_GEN1.zip I downloaded and BAM bricked again...my tablet doesn't like ICS now all of a sudden? Strange...
I then downloaded NVFLASH from here and installed skrilax's V8 bootloader w/recovery. Booted into recovery great, wiped the partitions etc. and tried to install the same ICS update.zip. BRICKED again!!!! Back to the drawing board...run EUUS...3.0.1 again...
So after days of working on this I decided maybe my Tab hates ICS now for some reason unbeknownst to me. Not very rational (lol) but anyway. I saw the JB ROM that's been put up http://forum.xda-developers.com/showthread.php?t=2239476&highlight=rom+ics and figured heck, why not, maybe the ICS ROM I have is corrupt. So I used NVFLASH, Skrilax's V8, and flashed the ROM...bricked again
I think the only thing I haven't tried is
I think I'm going to go crazy now.
Please help, I'm at wit's end.
More info:
I have acquired mmcblk0 (renamed to mmcblk0_start), my CPUID, and my SBK
I enable USB Debugging and Unknown Sources every time.
I have Windows 7, but also have UBUNTU installed on a Virtual Machine if the need arises.
Oh and I've booted into fastboot mode and run Babsector as well which did not help.
Hope I didn't miss anything. My brain is tired from working on this for so many days. I really want my A500 back! Either JB or ICS & rooted if possible!!!

Wow I thought I was the only one who had this issue. My A501 was working fine on Evil-A V2 (4.1.2) for many months and decided one night to crash and now stuck on V8 boot screen. Ive tried everything however I can get it to boot up on a 3.2 update.zip file.
The only recoveries I can get to work are TWRP 2.5.0.0 (on secboot)
Now I cant get it to flash anything other than 3.2.
It is formatted with ext4 partitions
whenever I try to flash it reboots to ACER download screen but the flashers wont get any further than that. (loads Acer boot recovery driver ok)
Any ideas?
Nice to know I'm not the only one. I hope we get some answers!!
*sigh* My situation has gotten worse. Now TDv4/EUUS won't roll back my device and my tab won't go past the recovery bootscreen (Just says "TEAMWIN" on the screen) That is the ONLY recovery that NVFLASH will flash to my device now, for some reason none of the other recoveries will go back onto it.
My stress level has gone up 800% from working on this. I don't have the money to buy a new tab. I really need to get this one working again.

I think my MB is failing/has failed. Either that or something I flashed to it was badly corrupted.
Now my tab has stuck itself in apx mode, bootloader won't load, recovery won't load, every program I have (nvflash, TDv4, EUUs, Babsector, etc) fails. Babsector gives me the fatal error "command 12 NvError 0x120002" and "setting device: 2 3" which I've read means that the tab is shot. Adb.exe tells me the device is not detected, even though all the drivers are installed correctly.
I'm pretty bummed because I don't have the money to buy another tab at the moment, and I used it ALL the time, took it everywhere with me.
On the up-side, I've done some research and it seems if you disassemble your tab and sell the working parts (things like the screen, metal back panel, internal speakers - obviously NOT the MB though!) individually on eBay you can make a bit of your money back.
Can anyone direct me to some good links/video tutorials for dis-assembly?
whoops... I just started a new thread with a very similar issue... My tab also just involuntarily bricked itself... I've made some progress but it's still in bad shape... I don't know about you guys but I had been running at a steady 50% overclock; do you think that could have led to this?
Sorry Man
No @rwilpstra....my a500 is overclocked to 1504 ghz and it runs just fine......as for you pareeeee....Sorry man.....your device is gone....no apx...no fastboot....no recovery.....it's beyond minor corruption....it's like you somehow managed to corrupt every single part of the memory and every partition that there was on your device....you're better off disassembling it.:crying::crying:
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...

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 all, when I try to use the SD update I get the upright Android with the green bar below & within a few seconds I get the dead Android with a red exclamation mark above his chest. Does this indicate a hardware fault or should I keep trying different update files? Thank you, hoz

If you have the correct update.zip you should be fine.
If you're trying to fix a brick you may need to use nvflash.

I've downloaded the OTA TOOL & am trying to download Acer APX/Fastboot/Recovery Drivers but the link in Where's my CUPID no longer works. I plugged my a500 into my laptop in fastboot mode but it could not find the drivers either. Any idea where i could find them? Thank you very much for your help.

If the rom you had on there was a Stock rom you OTA'ed, then afterOTA tool is the tool to use to Update the bootloader....you are soft-bricked so none of the tools are much use to you.
Which link in the CPUID guide does not work pls, I shall fix that. Try the one in the root guide in my sig.
If you are not currently flashed to skrilax_cz unlocked bootlader, fastboot will not work.
You're really best to start at the beginning in trying to unbrick.
This means downloading everything you need BEFORE you start.
That means:
Acers website for the acer drivers.
The root guide for the adb/fastboot drivers.
A rom to flash ICS, JB or stock rooted ICS.
The babsector.rar file to unbrick you.
You need to know how to get your tab in apx mode manually.
You also need to run the flash manually. Use the babsector file for that and post any errors you get.
Read thru the root guide in my sig, and make sure you have some understanding of what you're about to do. It makes it a lot easier to have all your files downloaded. The actual flashing process takes about 5 mins.
The babsector file will reset your tabs partitions, flash a recovery so you can do the formats and wipes before flashing your rom. Also installs the v8 unlocked bootloader.

The link under DRIVERS: Acer Support for Acer APX/Fastboot/Recovery Drivers. Just loads a Acer error page. I get the same error page when using the link in [GUIDE][ICS] Beginners Guide - Rooting, Flashing, Unbricking.
I downloaded the OTA tool to get my CUPID, tried blackthund3r A500 manager but I need BUSYBOX installed. What would be the easiest way to get my CUPID?
About 3 months ago I bought a manufacturer refurbished motherboard from the States (I'm in Australia) had my local PC shop install it, been working great. The other night it froze & I turned it off & then back on & its won't boot past the acer screen. It's stock, I haven't modified it in any way.
i have iconia a200 got brick
I think I'm having issue with the adb and fast boot drivers..not sure it they are installed. My tab only boots into apx mode. It will launch to bootloader mode while trying any of the tools. .but hands mid way. Doesn't seem the tools see it correctly because no atx devices are detected. The acer picassa driver goes I'm because I see the tab pop up. .but not sure the other drivers are right. So I'm stuck.

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.
