Last night I got sick enough of running out of room for apps on my Aria that I finally decided to just install Froyo. Froyo, along with many other cool features, has a way to install apps to the SD card where there is plenty more room than on the phone itself. The process was way easier than I thought it would be, and after using it for a few hours seems just as stable (to me anyway) as the stock OS. These are the steps that I took to get Froyo installed:
1) Root the phone with Unrevoked3: http://unrevoked.com/recovery/ I ran this from Linux with no problem.. didn’t have to do anything other than start the application and plug the phone in.
2) Created a backup by following the steps here: http://forum.xda-developers.com/wiki/index.php?title=How_to_backup_or_recover_via_Nandroid (Note, the button combo for Aria to boot into recovery mode was holding down the VOLUME DOWN while pressing the power key while off.
3) From the menu, after backing up everything: Wipe Data
4) Wipe Dalvik Cache
5) Download the liberated_aria_FR007_signed.zip rom from here: http://forum.xda-developers.com/showthread.php?t=819715 and copied it to my SD card.
6) Boot up in recovery again and installed ROM from SD.
7) Booted Froyo! There were a couple additional steps to get the apps to the SD card, they are detailed in the thread from step 5.
Couple of notes: I suppose that I could have recovered my apps from a backup, but I didn’t, I just downloaded them from the Market again. Everything else that I needed (contacts/calendar/etc) were all stored in the cloud and were there again after setting up my google account. Don’t forget to read as much as you need to of the instructions.. I’m sure that I’m leaving out some detail that is covered there.
Thanks to everyone from forum.xda-developers.com and unrevoked for making this possible!
