[Acer Iconia A500] codemansGT:
My update keeps failing 4.010.07 to 4.010.10. I have all my original apps installed of course and unroot using iconiaroot1.3.apk then i restart. Go to start the update it restarts then im stuck with an orange triangle symbol. I have even taken out the sd card reading that some people have tried that. I installed 4.010.07 using cwm, not sure if that matters or not. would be nice if i can update without wiping my device like i had to do when i use cwm. im going to post my long from /cache/recovery/last_log. I think the problem has something to do with itsmagic but not sure.

Fixing A500 Boot/Recovery Checksums...

Running itsmagic

Some magic trick by @sc2k on xda

it tricks the bootloader to run any kernel you want.

Thx @Acer for making this so easy.. why did you say the BL is locked if it isn't?

USE AT YOUR OWN RISK!

Done. Have fun!

Done!

Finding update package...

I:Update location: /cache/acer_ug/update.zip

Opening update package...

I:1 key(s) loaded from /res/keys

Verifying update package...

I:comment is 1690 bytes; signature 1672 bytes from end

E:failed to verify whole-file signature

I:verify_file returned 1

E:signature verification failed

Installation aborted.

p.s. i think the problem is because i used cwm to get 3.1 i dont have a stock bootloader? so my question now is how do i get a stock bootloader. i would like to do future ota updates because its simpler.
