So, the big question is: Has anyone been able to pull today's OTA with their leaked 2.2?
Do I really need to revert back to 2.1?
I downloaded the first 2.2 leak from P3Droid.
This apparently is a touchy subject, people were asking this all over the forum, then rumors started flying it couldn't be done, then moto stepped in with threats, people got hit for posting certain files to revert and now if you even mention "do I have to revert for OTA to apply" you see /duck ... mod delete
ect.
I apparently wasn't on the forum
every single day so I too must have missed something in between the above events BUT to answer your question, yes, you need a stock OS before the official OTA will apply. I have the first leak, honestly love it, but I've been trying to force the update since 10pm last night with no luck, so I personally can confirm that the first leak needs to be reverted, there was another one but that was in the foggy area I speak of above.
I've hinted at this question and never got a response either, so apparently its been questioned to death no body will truly give you the run down.
On a side note, birdman still retains the first leak and is working on a new 2.2 zip that would apply the same OS the OTA provides - relax and see how this OTA works before doing anything you don't think you can handle (i've prepared myself for this day, see sig) sometimes when these first role out there could be more bugs than the leak, who knows - only time will tell.
