Are you still able to boot to recovery by pressing Volume-Down + Power?
Have the same problem on my a501, but recovery doesn't work, too. There comes the message SOS Boot Checksum failed. Hope, someone can help me.

Are you still able to boot into Android? if so, download Acer Recovery Installer and use it to install a cwm. It'll fix the SOS checksum issue by running itsmagic.
SOS checksum fail
Hello
My A500 also has the SOS checksum error.
When it boots in only gets to the Android System screen then there is a message that it is poweing down but it doesn't.
I can not navigate to install recovery touch screen is inactive.
Can not flash because of the SOS checksum error.
Help!
Fixed it!
Used EUUs_SBK_Acer_A500_1.016.05_COM_GEN1
That fixed the SOS checksum error
and several reloads of unstable update.zip
Then OTA updates Tablet is alive!!
t_r_j could you explain a little? First. I found EUUs_SBK_Acer_A500_1.016.05_COM_GEN1 with google. It was a rar achive. Should new roms not be a zipped archive? What do you do with it?
/Mikkel
Unzip it and read the PDF inside the rar
hmm.. no pdf inside. Only a very little readme.txt. I'll try with that. Thank you t_r_j

To get back to stock you'll need to run an official a501 EUU - theres a thread in the dev forum by blackthund3r with a list of official Acer Roms -
you need an "EUU" AND I hope you have saved your cpuid from using afterOTA - you can't do anything now without it

I have download a full rom A501 first and install thats work great after booting up it wont start and give the error.
Yes i have olso save my Acer id tekst with spuid serial number like that.

Well, that is good news, you're halfway there
This tutorial will give you some background on rooting and installing CWM http://forum.xda-developers.com/showthread.php?p=35500631#post35500631
But now you have the v8 and access to fastboot the first thing you should do is to hook your usb cable to your pc and run a command prompt from the fastboot folder (if you need help with doing that have a look in the cpuid guide linked in my sig). You want to wipe /data and /cache and then immediately flash an ICS custom rom...civato has a thread with official acer stock roms that will run on the v8 or you can choose a full custom one.
You should already have a custom recovery on your tab, if not, use fastboot to flash one after you did your wipes...then boot to it and flash your rom not an update.zip
i have hook the usb cable but i cant write somthing on the cmd
its noet working, i want to install CWM this was verry easy to use.
I dont now why its verry difficult to root and install a custom firmware on a Acer Iconia A500.
I have olso a Samsung galaxy tab, this was veryy easy to use after 3 minutes it was rooted and installed the CWM.

Go to cpuid guide in my sig
You'll need the drivers installed correctly, there's a section showing how to do that....you'll need to flash the v8 bootloader to get cwm...its all in the guide

First to thanks to dibb_nz, civato, Moscow Desire & Heisenberg.
I have installed Skrilax CZ bootloader V8 on my TAB ( after six month trying )
Then Installed: CWM recovery v5.5 thor2002ro rev.1.7.3
showing: kernel 3.1.10-digetx-thor-4.4micro
Bootloader: 0.03.14-MUL
Active boot partition 1st boot partition set as default.
Not running HC bootloader, itsmagic not needed.
As per your instruction on (Skrilax CZ bootloader V8) wipes all the /data and /cache using fastboot method then reboot and after going to CWM recovery flashed Civato official acer Rom Acer_AV041_A500_1.041.00_WW_CUS1 from here http://forum.xda-developers.com/showthread.php?t=1633907.
But again my Tab is stuck on Skrilax CZ bootloader V8 bootmenu.
now help me what to do.
Is there anyone who can explain to me how I can remove Team Win Recoverey twrp v2.4.0.0 and how to install afterwards Team Win Recoverey twrp v2.1.3.
My Acer A500 starts only in the Team Win Recoverey twrp v2.4.0.0 modes.
Backups are on the tablet and on the external sd card but it is not possible to install them.
Error error ......
After a reboot I see: "Secure boot: image checksum Link Fail!"
I want to install ROM "CM10-FLEX_V6Supercharged_Rev2.3_GappsIncl_Public " but this is not possible with twrp v2.4.0.0.
To install TWP 2.1.3-Triumph.zip with twrp v2.4.0.0 gives "Failed".

I tried to install:
- Ezterry A500's Pub Recover
- Thor 1.7.3
- Ra-recovery 3.17 (recovery-ra-Iconia-3.17-GNM)
During a Reboot each time TWRP 2.4.0.0. is the only one to start so I can't install anything else.

18-02-2013
I also tried:
- The hard reset.
- The reset with a paper clip.
- Several other ROMs but these do not work with twrp v2.4.0.0. Only ROM "Acer A500 Slim 01-14-2013 (1st Release)" should work. But unfortunately I can only see the ACER logo. Even after 1 night waiting you still see the ACER logo.
- Start all over with "Blackthund3r_A500_A501_CWM_Root_v2" software is also unsuccessful.

Only a boot with recovery "twrp v2.4.0.0" still succeeds.
This gives a error message "Unable to locate zip file '/ sdcard / SDCARD: update.zip".

Is there anyone who can help me. It doesn't matter anymore what rom I put on as long as it works.

Can you install THOR's 1.73 recovery? If so, then you should be able to flash the ROM you mention, That's how I did mine.

- Ra-recovery 3.17 (recovery-ra-Iconia-3.17-GNM)

What should I do?
Thanks for any help.
You'll lose all data, so pop out your external micro card, but you might want to try the hard reset...the one where you toggle the orientation button. Have you tried that?
I also tried:
- The hard reset.
- The reset with a paper clip.
- Several other ROMs but these do not work with twrp v2.4.0.0. Only ROM "Acer A500 Slim 01-14-2013 (1st Release)" should work. But unfortunately I can only see the ACER logo. Even after 1 night waiting you still see the ACER logo.

Have you tried flashing a "back to stock ROM". That would also install the stock recovery and remove root. There are XDA threads on this.
Good luck...I hope you get it fixed

I have bricked my ACER and phones several times (and a few times it seemed as if I wasn't gonna be able to restore them). But I always got them running again.
Might take a lot more googling, but you'll eventually figure it out.

Yessss, I did it . The problem consisted of two problems.
1) APX driver reinstalled.
2) Installation on a Windows 7 PC. (Windows 8 will not work)
Then start all over with "blackthund3r_A500_APX_Flash_Tool_v0.4" software.
What a great tool.
Special Thanks to blackthund3r

CONGRATS!!!
Hello,
I read a lot of threads but I'm really tuck...
When I power on my Acer Iconia A500, I have this error message : "Secure boot: image LNX checksum fail!"
According to my research, the issue is the bootloader. So I want to update (change) this.
When I power on my tablet in recovery mod I don't have this error. My recovery it's TWRP v2.4.4.0 (Team Win Recovery Project).
I have not my CPUID, so I downloaded Afterota and install the official driver Acer.
But when I plug my tablet, second step "Usb Connection" I have this issue : ERROR - connect usb cable and enable usb debugging"
But I can't enable usb debugging because my ROM is fail...
I hope somebody can help me because I have no idea

If you do have recovery mode then a) go in and format data and cache,
b) flash custom ics/jb rom....
c) It will show you your cpuid....
I have not my CPUID, so I downloaded Afterota and install the official driver Acer.
But when I plug my tablet, second step "Usb Connection" I have this issue : ERROR - connect usb cable and enable usb debugging"

You can only use afterota IF your rom was a stock ics updated via OTA...was yours????
