Apx. Mode. Nvflash a stock bootloader. Send it in.
Theres a thread in the development section, bootloader thread on how to recover from your error.

Your recovery is borked!!! Just install again...
you still have a working system to boot into??
Install acer recovery installer from either the market or
the apk from the thread in Themes/Apps and install yr recovery of choice....
acer recovery installer will also tell you what BL you are on...
If you cannot boot at all...
Just manually enter apx mode and run either nvFlash or EUU back to stock 3.2

[Q] Bricked?????

Can someone please help or toss me some suggestions on how to unbrick my tablet without sending to acer if possible this is whats goin on. It was rooted and running fine with CWM 1.7.3 from thor then the other day i turn it on and bootloop at bootanimation. i then enter recover to wipe and flash as usual but when i goto wipe it says error removing /data/data/com.android........... I heard my data partition was corrupted and proceeded with trying to really format that to no avail fearing my tablet was bricked i followed another thread titled how to unbrick your tablet!!!! it installed OTA ICS and wiped my recovery :crying: so now i have stock recovery and bootloop and the pc still recognizes the tablet in fastboot and APX mode but when i try to format /data in fastboot it says bootloader locked :crying: and when in apx mode when i try to use nvflash it says error during usb write then it says usb device not connected until i restart apx mode fresh. in the stock recovery it will flash OTA packages and finish install but still stuck in bootloop otherwise i just get the dead android guy with a red exclamation point. Any help or suggestions would be greatly appreciated.

Have you tried installing the patched bootloader? Remember, you have to have your SBK number you got from your UID. I found that NVFlashing using one of the earlier releases works best for me.
Also remember what OTA update.zip you are installing. Some of them, are just update patch files, which require a specific OS to be installed.
Did you try this thread?
http://forum.xda-developers.com/showthread.php?t=1699277
Basically, you decrypt the 2 update files, extract the contents of one on to your SD card. Try booting to stock recovery and see if it installs and boots.
If that doesn't work, then do the same with the other update file.
The 50x is basically bullet proof. There is always a method, and sometimes, it's finding the method that works is the hardest.

I did finally get it. I let it bootloop hooked it up to my pc and used adb while it was bootlooping to get my cpuid and sbk since i had neither of those i couldnt do jack with nvflash. After i got those went back in apx mode flashed bootloader and cwm again followed thors instructions on how to really format data partition and installed rom like normal. Worked like a champ, but without cpuid and sbk i woulda never fixed it

"Boot Recovery"
go into multiboot menu and "set 1st boot partition" as default
and reboot or do a backup of your existing rom, do your wipes and flash jellybean again...this should fix things up for you
multi boot doesnt quite work the way we'd all like!!!

[Q] Acer a500 recovery issue.

So i have a Acer Iconia A500 and i have Android 4.0.3 Kernel Version 2.6.39.4+. I want to root it but when ever i try to get it into Recovery mode i get a android on its back with a hatch open and a triangle coming from it. I have performed a factory reset and still am unable to get into recover. I tried the Acer Recovery App and it says it does not recognize the model number. I have a buddie who works in in a tech support place and told me to download "SD Acer AV041 A500 RV17RC02 PA CUS1" but i am unable to find that file. If somebody could help me out that would be great.

I had a similar issue and I had to install an unlocked bootloader. I just installed Civato's ICS 4.04 RE-FLEX and got around the the issues. You will need to installed the TWRP 2.13 Recovery that includes the unlocked bootloader first. Do a search in A500 Development section for the ROM below.
[ROM][KERNEL]ICS 4.0.4-RE-FLEXxx + CiVz_StormFlex OC Kernel (13-Mar-2013)

cant access fastboot and recovery, help please
no section for the a200 so i got nowhere to ask so please help.
help: acer a200 cannot enter into recovery or fastboot
i got into recovery and flashed the acer stock rom (i think its a honeycomb 3.2.1) then i mistakenly flashed onyx kernel which is for ICS. when i rebooted the tablet, an error message appears : "boot verified failed..." When i tried to get into recovery by pressing volume down and power, the following text appears:
SD update cmd: recovery
--update package = SDcard:update.zip
booting recovery kernel image
recovery verified failed
i tried to boot into fastboot by plugging it into a computer and update its drivers when the "starting fastboot us download protool" appears but nothing happend.
also, the stock rom i flashed lcoked the bootloader.
what should i do. help please.

Dead A500

I think my A500 is dead. It was a good two+ years of service I suppose.. but disappointed none the less. At first it started out not booting... but I could eventually get it to boot after hitting reset a dozen or so time... now that doesn't work. Moving on... Go the Galaxy Note 8 as a replacement and love it.

if you can get your PC to detect your a500, you could possibly restore it with a stock or custom os

Any tips on how to restore a ROM via PC

I tried putting an update.zip on a microSD card, and when I tried to reboot, I got the following:
Erasing Cache before SD Update...
SD update cmd: recovery
==update_package=SDCARD: update.zip
Booting recovery kernel image
Recovery verified failed ...
