You have to downgrade to 2.2.2 or 2.2.1 if you like....I'm pretty sure you can't just unroot cm7...correct me if I'm wrong...

Question: Why would you need to downgrade to sell it.
Then it's just a used M.
If you look in this forum, everyone wants gingerbread.
I personally think you will get more for your phone if you keep CM-7 on your phone. Just show the new owner how to get into the recovery,restore,etc.

The reason for reverting to stock is because OTA activation may fail on a custom ROM.

Ok, can you keep the CM-7 ROM nandroid backup,and the custom recovery. Just flash the stock ROM, activate, restore the nandroid?
