So, this is really frustrating me. I even redid the entire process of using the 2.3.20 SBF file, downloading the official OTA update, rooting the phone, installing ROM Manager and the boostrap, then installing the September 8 build of CyanogenMod 7. I then booted it, rebooted ClockworkMod Recovery and installed the Google apps.
However, it seems like the majority of apps don't want to download. Some of them will, the ones that phone just automatically re-installs from my purchase history. But other ones, rather IMPORTANT ones like Titanium Backup Pro Key (you know, so I can skip the massive redownloading of 200 apps and just restore my backup with one-click?), it gives me a message saying "[Name of app] could not be downloaded due to an error". I've wiped the data and cache plenty of times, this stupid thing keeps happening. Google apps like YouTube say they're starting download and just sit there for hours.
I really have no idea what's going on here, but this is a fairly serious problem. I need to be able to install apps that I previously paid for!! Anybody had this happen to them or know of a possible fix?
Also, on a slightly unrelated note, the ALT Lock key on the slide-out keyboard doesn't work. Not sure if this has been reported or not.
