Looks promising thanks for putting this up! I look forward to seeing if this successfully works on the various types of bricks.

Edit: Not sure what's up with your links or hosting, but yeah...doesn't work, just ads, then redirect to ....another ad. No download.

Edit2: Ok I've tried 6 times, no download, and I should mention links like this are frowned upon by XDA Mods, so you may want to switch to a host that doesn't require going through steps to get to the download, like dev-host. Looks like now I can't go past unless I sign up for something, which I may or may not agree with, which is kind of forcing users. Or I'm blind and not seeing it, always an option too lol

Np just thought I'd report what was happening. I can mirror on my dev-host as well if you'd like.

In my case it does not serve for anything. Because as it does not recognize me the tablet by any means. The usb does not even sound when I connect it .... it is a pity, tomorrow a messenger comes to take her to him to the SAT. but thanks for the work
I have a photo of the current condition of the tablet, but they do not stop me to place external links...

asi se encuentra mi tablet. h t tp ://w w w .youtube.com/watch?v=G-TDTX-wvy4&feature=youtu.be

but this defiantly got me farther then any other thing

This won't get any farther then any other current method on a locked boot loader. This is for those having issues with recovery not responding so a rom install isn't possible.

What kind of brick do you have? There's a few kinds now.

I don't know what type it is if I had to guess I would call it a complete brick but fastboot works (locked mode) and it sometimes will work with adb (also in locked mode)

The last step...

-- Install /sdcard/cm9-7-9-B29-a100-PM.zip ...
E:failed to mount /data (No such file or directory)
E:Can't mount /sdcard/cm9-7-9-B29-a100-PM.zip
E:failed to mount /data (No such file or directory)
Error flashing zip '/sdcard/cm9-7-9-B29-a100-PM.zip'

So close... but failed

you shouldn't be use it on a locked bootloader, or an official acer rom, otherwise you be locked out by the bootloader

1. download this tools and extrackt -multiupload -night.dyndns.org
2. get into fastboot power of device then power on hand hold down Volume Down when the first screen appears push the screen lock below are 2 pictures
3.in fastboot connect usb and run the first script this will copy the recovery (A100 TWRP recovery (TeamWin Recovery Project) 2.1.1+)

That md5 error is normal, and isn't causing the install to fail, its the pretty much brick status your device is in that's causing that. Basically all those errors are saying you have no partitions on your device, so it can't do anything until that's corrected.

any idea where to start or how to get it back so i can return under waranty

Get it back how? Acer knows of the problem so just use the warranty.

Edit: sorry just realized what you meant. Sorry but no in its bricked state you can't restore it back to normal. You could try to fast boot the stock recovery and adb the stock boot loader, but it may or may not work. Doing any if the Modding voids the warranty anyways.

i ment to remove the recovery and the unlocker

What's the command for flashing the stock bootloader blob file?
