[FIX] Market Not Downloading After Downgrade From Froyo Back to 2.1 ROMs

---

Hi all,

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 .

Extra:
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 !

Thanks, I was having the same problem and your steps worked for me

Happened to me too. All I did was flash old radio and all was well. Didn't have to do all the rest.

I did flash the old radio, as did @minamiki but it didn't help us. Also, it didn't FC, rather, it hangs at "Starting downloads" . Glad it helped at least one more person!

I have the same problem so will try this now and report back

EDIT: Fantastic, all fixed and working. Thanks

Oh man! This thread is coming in 12 hours too late. I came to the same conclusion as you guys did, wiped, loaded up cyan7test3, logged in, and yes, market was back again. The only difference is, I didn't follow this up with a nand restore, but painstakingly (and painfully) went through a Titanium app restore routine. Everything works now, but man I wish you'd posted earlier

So it seems Google does store some information on what ROM version you're on :P.

I tried dalvik wipe, clearing market data, removing the market update, etc. none of it worked. Doing a full wipe & reinstall got it going again though, cheers!
