I have an ADP1 (among others) and was having some problems with it. Long story short, it ran fine for quite some time, I installed cyanogenmod 4.2.x on it awhile ago and then 5.x on it a few months ago. About a week ago it started acting up - lots of program FC's, including gvoice, gmail, seesmic, and sometimes the phone would just simply lock up while I was using it. So I started troubleshooting it and am getting frustrated. Now I have it kind of running - it's not bricked, and most of the core apps work now, but some (like Market) say "Application not installed" when I try to launch them. So, my question for the forum is do you think I should: a - follow the instructions on the HTC ADP1 site to restore it to the original 1.6 system image, radio, etc., or b - upgrade to cyanogen's 6.x ROM, or c - do something else? Model Number Android Developer Phone 1 (rooted g1) Firmware Version 2.1-update1 Baseband Version 62.505.20.17H_126.96.36.199I Kernel Version 2.6.34-cyanogenmod Build Number EPE54B Carrier: AT&T Country: US I've put a Transcend 8GB class 6 sd card in it and it had been working fine with that for at least a few months. Any advice or thoughts would be appreciated.
