I flashed my N9 via NaviFirm back to proper PR1.2, the keyboards are finally IN, phone acts pretty cool but I can´t open/send/receive any mail, I can´t go to my Facebook and my Gallery is empty....
I re-installed my accounts twice, rebooted twice but once I open Mail app it says "Set up your mail"...but check this: I can see all of my accts in Accounts app, I can even log on to Fbook, Gtalk, Skype and see the green icon...but no access to mail app at all...once I start setting up new mail it says the mail already exists...totally insane...

@gallery: I copied some pictures to the phone while in Mass Storage, I can see them all in Filebox @ PIctures but the Gallery app is empty...

I did the same with some music and no problem there....

WTF???
Is there official PR1.2 on NSU yet?
AFAICR the NSU is always the most reliable way on how to update the phone properly...I had similar issues after some flashing PR1.1 before, once I re-installed the FW via NSU, the problems were gone...
