With Team Win updating their new recovery to include a touch interface and new features to what has been dubbed TWRP 2, developers for devices that weren’t initially supported have been working on making the new touch recovery a part of their device’s repertoire. While most haven’t received the touch enabled awesomeness just yet, those carrying the Acer Iconia A100 have, and they can flash it immediately.
XDA Senior Member ZeroNull has ported the now popular touch recovery to the Iconia A100, which makes it the second Iconia tablet to receive the touch recovery after its cousin, the A500. The recovery, which is actually based on the A500 version, is relatively easy to install. However, users do have to be running certain firmware first. Says ZeroNull:
Before anything make sure you have the latest ICS leak C/O Vache, Root, and Unlocked Bootloader.
So if you don’t fulfill those requirements, you should steer clear of this for right now, as it’ll probably won’t work. For those who meet the prerequisites, the installation instructions are a cakewalk. Simply download the included package, unzip and run the install.bat executable file on a Windows PC, and wait for everything to settle down. Once it does, you’ll have TWRP 2 on your A100.
