Problem with ActiveSync since patching EXT_ROM to Bigstorage

[Moeppel]

Hi, since I've updated my ROM to get a BigStorage EXT_ROM, I can't sync anymore. ActiveSync starts and connects, says "looking for changes" and disconnects immediately. Hardresetting my MDAc didn't change anything, clearing old partnership and establishing a new one didn't work also. I can only connect as a "guest". Tried it also with an older image of my Windows XP Home System, but failed. I received an crc error message after updating my ROM with the patched one, but the the MDAc seems to work (except ActiveSync) and the BigStorage is available. Any ideas?

Hello, anybody out there?

Hiding and locking ExRom have no result :(

ActiveSync v4 return error:
"Critical communications services have failled to start. Try resetting the mobile device, and then connect again."

With a ActiveSync v3.8 all works ok!
