[FIX] Market Not Downloading After Downgrade From Froyo Back to 2.1 ROMs
Myself and @minamiki were having problems downloading from the Market after we downgraded to CM5.0.6/7 after upgrading to Froyo. After numerous attempts, we figured that it was due to Google's servers storing some information that we are on 2.2, and now we're on 2.1 it's just not working. We tried re-checkin, clearing market data, all to no avail. We also downgraded our radio.
Finally, we decided to wipe, and then flash a 2.1 ROM again. This will cause the welcome screen and log-in screen to launch on bootup, thus, re-signing into Google with new info so to speak. Once done, restored our backed up ROM, and Market downloads are working again. I'm on CM5.0.7-T3 running Froyo's radio, and @minamiki is on CM5.0.6 running EPE54B's radio, FYI
Note: What we assume is purely our guess, but it has worked for us. So, here are the quick steps:
Step 1: Download a 2.1 ROM, such as CyanogenMod 5.0.6 or Enomther's 1.9.2
Step 2: Nandroid backup your current 2.1 setup
Step 3: Wipe, then flash the downloaded 2.1 ROM
Step 4: Upon phone reboot, sign into Google
Step 5: Go back to recovery and restore the nandroid backup
We've confirmed this to work on CM5.0.6 and CM5.0.7-Test3
We did not try removing and re-adding a Google account without wiping, but that *may* work as well.

that usually forces you to sign in again in market.
I didn't have to use this when i downgraded from Froyo since my Market was working, so it's just a hypophysis.
Hope it helps
