Hello all, thanks for your support.
Now, I do all the same progress from bro C4Eva's video.
The process is quite simple, but one thing that happened to me but not on video is, when I still on 3.0 unstable, the Force Close is really quick, and I can't input anything because when the keyboard showed up, it will be forced to close. So, I have to using USB keyboard to input my search query "acer recovery install" on Android Market.
Now my Android version is 3.2 and it's rooted (I have icon superuser on menu), thanks a lot.
But, I have issue here, (fyi:my Iconia is A501)
1. The model number on "About tablet" is A500, not A501.
2. Looks like I'm missing my 3G Support, the signal says (No service) even if I already have SimCard inserted. I already tried to remove and insert it back.
I think I'm losing my 3G Support now. Can you help me about this issue?
Thanks a lot.
