I have a T Mobile LG Optimus phone, with Android 2.1. I had moved every app possible to the sd card but the internal memory was always running low, so I used z4root to root it and had planned to get rid of some of the bloatware I don't use (most of what came on the phone). I used titanium backup to backup everything I wanted to un-install, did the uninstalls and after trying to reboot, the phone would not get past the ANDROID opening screen. Both soft and hard resets did nothing. I finally found upgrade software on the LG Optimus site and used my computer to install that and the phone now at least runs, with 2.2. However, I can't get it to recognize the apps I had on the sd card at all; yet if I try to redownload them and install, it reminds that they are stored on my sd card. I don't mind reloading everything but then that's just more room taken up on my sd card. When I go into the Show Apps screen, when I click on the sd card it shows absolutely nothing. I tried backing up the card to my computer, reformatting the card in the phone and then recoyping it all back over. I'm guessing it has something to do with the change in Android? Do I just have to reformat the card and start over with the apps?
Also, I'd still like to eventually repeat the rooting/un-installing of junk; however obviously I got rid of something necessary to the sytem. Is there a list somewhere to help me figure out what the necessities are so it doesn't happen again?
btw, both Titanium backup and z4root were on the phone's memory so those are no longer present, to interfere with the sd card or anything AFAIK, although I guess the backup files were put on the card.
thanks from an obvious non-geek about phones.
