Hi; I am a user of Acer Liquid E with build number "Acer_LiquidE_1.100.41_AAP_GEN2" and firmware version of "2.1-update 1". I am looking for the latest 2.2 version Android. So, I been search from the website and manage to get info about "FIDO & ROGER" 2.2 version installer but; after i downloaded and save it into my phone, both of the installer is not working and fail. Is there any others version of 2.2 software to suit my handphone version???
