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

Hi
I am currently trying to install thor_rom_v14.2.zip (ROM) to my
Pb liberty tab said to be the same as acer iconia A500.
The stuck version is android is 3.0.1
But every time I try to start it in recovery mode I get
"secure boot img SOS check sum fail!" and the boot process stops.
I've rooted it with gengerbreak
installed ROM manager from app store. It does not recognize the product under the installation and asks me to confirm that it is an asus transfomer which I did although it was certainly not an asus trnasformer. All the things I tried with ClockworkMod Recovery (CWM) led only to a boot that stopped by "Secure boot img SOS check sum fail!"
So I tried with acer recovery install v2.74. But here I got exactly same result. I could not get past the "secure boot img SOS check sum fail!".
So my question obviously is. How do I get about this "Secure boot img SOS check sum fail!"
Should I perhaps get hold of an older version of the Acer Recovery Installer that has ClockworkMod Recovery rev.1.3.4 by thor2002ro with it? If yes how to I get it?
Other proposals... could I do this in a completely different manner? like from a USB connection from a remote computer or with Unix dd command or???.. How could I get about this?
