• Kernel and TWRP includes patches aimed at brick prevention
• Resolution is set at native 1024x600
• Very fast actions and touch response
• Backward compatibility with previous releases of TWRP
• Compatibility with all Ice Cream Sandwhich and Jelly Bean ROMs for the A100(HoneyComb should be compatible too, however currently untested)
• All previous features from TWRP that you may be familiar with are included

Mount Point Information:

• External Storage - mountpoint= /external_sdcard
• Internal Storage - mountpoint = /sdcard

Instructions:

Automated Installation (Windows/Linux):

• Most importantly you need to have all drivers required for adb and fastboot working on your OS, this shouldn't be a concern for linux users, however it may be for Windows users as it is picky about adb drivers.
• Download the above Automated Install .zip file for your operating system
• Extract the contents of the Zip to a location on your PC's hard drive
• Change to the extracted directory's contents.
• Run the installer; On windows you may just double click the install-windows.bat file, on linux you need to run the install-linux.sh script
  example linux installation commands:

  cd a100_twrp_installer_linux

   bash ./install-linux.sh

• Read the on screen information of the progress. If you get any errors you will need to resolve the issue or try one of the following alternative install methods.
• If you need more detailed installation instructions please read the INSTALL file included inside the .zip

Manual installation:

1. Download the .img file for the recovery
2. Connect your A100 device to USB on your PC
3. While your A100 is booted in either Android or Recovery just enter the following into your PCs command prompt/shell:
   

    adb reboot bootloader

4. Now flash the image - at the command prompt/shell enter:
   

   fastboot flash recovery openrecovery-twrp-2.2.2.1-a100.img

5. Reboot the device - again from the command prompt/shell:
   

    fastboot reboot

6. Enter Recovery mode - While tablet shuts off, hold the Vol - (down) button until you see the screen saying "loading recovery kernel"
7. Checkout the new TWRP build and enjoy!

Flashable Upgrade Instructions: (flash just like you would any other .zip, but here are instructions anyway)

• Download the Flashable ZIP above
• Save to a location on your tablets internal or external memory
• Boot to recovery
• Choose the file a100_twrp_upgrade_2.2.2.1.zip in the install menu
• Swipe to install
• Wait and DO NOT Disconnect your A100!
• When finished, go back to Main menu - choose Reboot - and Reboot Recovery
• Enjoy the Official 2.2.2.1 TWRP Release!

And don't forget that i forgot the download link!! lol **fixed haha

 

[Fransis88]

Broken links, so you can correct it.

Broken links, so you can correct it.

Thanks francis88, i just tested them on my end again (btw the hosting server is remote from me) it worked for me, so maybe you should check if you have an adblocker or some kind of ipfilter going on? possibly the host was having issues too, but the links works for me at the moment. tested both github sources and the download link to the img. Thanks again

*Edit: Please keep in mind I am using androidfilehost's beta site and they are doing quiet a bit of changes to the site lately trying migrate users from the original site over to the new, and once they get everything settled in and the 'beta' goes away everything should straighten back up. I really like the services at 'androidfilehost' and the owner is really great at working with devs, so please be patient as they continue to upgrade their servers to bring us superb file hosting services. If a link appears to be broken, please wait a few minutes and try again, if the link is down for a long period of time please contact me in PM so that the thread stays for discussion about the TWRP Recovery. Sorry and thanks everyone

Perfect, i have been able to download it. i had a very bad experience with CWRP, now I only use TWRP apart from the fact that their options seem to me much more practical.

So let me know how you like it. Also if you happen to be a linux user, I have wrote an automated installer script for linux, Xbow59 is currently writing a windows batch script for installation, I currently have the Linux installation working though if you'd like to test/try it out just let me know. Windows users can look forward to an automated solution within a day or so

help :/........ i am on stock rooted ics. i just unlocked the bootloader sucsessfully and went to flash this. flashed the recovery. and when i try to boot into recovery i get the dead android guy with an ! in a triangle above him......... should i flash recovery again or try to boot into recovery again? i just dont want to mess anything up.

edit: im just scared its trying to update a stock package. i had an update a couple days ago and tryed to update but it failed since i deleted a bunch of bloat, no problem. but i dont know where it downloaded and if its still there trying to install.

By unlocking the bootloader successfully, what exactly did you do? If you flashed the btl100 file to the device that's not successfully unlocking, in fact don't touch that 100 file again. Hopefully you followed the guide and used the A200 bootloader unlock method. If you followed that guide though you wouldn't be getting the dead android looking guy. Be careful with this stuff, can easily brick!

i used that method (only one i know) and i got the distotrted green acer logos and it says its unlocked. after i followed the steps to install twrp and it went smoothly. until i tryed booting into recovery. should i try to boot into recovery again? ive rebooted a few times so im still safe if i have to power off. OR should i try to reinstall twrp and follow the guide again. because i am CERTAIN i am unlocked. before i had to send in for repairs i had it unlocked but of course they relocked it.

(btw im not getting angry or smart assy with you haha,if it seems that way i dont mean it to come out that way)

Delete or rename /system/etc/install-recovery.sh then install twrp again.
its overwriting your custom recovery every boot.

I had forgot all about this, even though it is in my unreleased linux auto installer. If by chance you are using linux, I have an installer that will do this all for you the right way, I just haven't posted it yet because I don't have the windows installer fixed

you can either download the linux installer git repo and just extract it to a directory named twrp_install or similar; just run sudo bash ./install-linux.sh after you are in the install directory. https://github.com/godmachine81/Acer-A100-TWRP-Installer/zipball/linux <<current linux installer for a100 twrp


Or you can clone the repo

git clone https://github.com/godmachine81/Acer-A100-TWRP-Installer.git

then checkout the linux branch:

git checkout linux

then install:

sudo bash ./install-linux.sh

The git method requires you have git installed, you will probably just want to install from the zipball method if you don't already have git

aahhhhhh. thought it was something of that nature. now will i have to delete/rename and reflash twrp every time i need to flash something? or will it stick once i sucsesfully flash it?

will report if it works in a few seconds

edit: noobness showed there. haha thats a script to reinstall recovery at boot so once i delete it it wont reflash stock recovery right?

edit edit: nope, im not on linux (yet) my computer is a mess of three harddrives and messed up registrys and unofficial windows 7 haha. once i buy a copy of windows 7 its a full wipe and partitioning for a windows/linux dualboot

EDIT EDIT EDIT: SUCCESS now i flash linux's kernel
Thanks for the help you guys. once i get some money from the boss man i will gladly donate a little something something for the cause

Also I noticed you mentioning that you are using a stock rom, you might want to talk to pio_masaki about this; but to my understanding the stock roms from Acer are not suppose to be flashed from custom recovery. I have read different things on this, however I haven't ever attempted to do such, from what I can tell doing this can or will brick your tablet by overwriting your bootloader and failing to install android, giving you no way to get to recovery nor android.. Might be something you want to discuss with him sometime.

In your kernel thread he mentioned staying on stock for stability, so I don't think he'll be flashing off stock anyways. Not yet anyways....

Restoring stock works as it leaves the boot loader alone.

Thanks, just trying to look out for these newcomers - however I'm still a bit confused at which causes the brick. The way I first interpreted it, it was flashing any Acer packaged update.zip from a custom recovery that would cause it. Then someone said that only the HC zips would. So to play it safe, I believe I'd double double check as many times as possible before I flashed any .zip from Acer from either twrp or cwm if it was me. Wish there was some clarity though on which Acer zips are SAFE and which ones are BRICKs -n- a Zip lol

The ics Acer zips are known brickers but it happens for a reason I'm not very clear on. HC will also brick it.

Basically there's a chance it will run the zip, attempt to flash everything, however for some reason it will fail to flash system or boot correctly, but does replace the bootloader. What I'm not clear on is why it fails on system or boot but succeeds on bootloader, or why recovery doesn't error flashing it.

Once this situation occurs you get locked out of both recovery and system by the bootloader, no adb or fastboot access to correct it.

Using the information I've gathered on this I've been working on a method to restore to stock if needed, but its going slow as I have to triple check everything before I even test it. Its a long and annoying process but should result in a 100% factory stock system.
