ROM Update (O2 Germany) 1.25.207.2 and GPRS/UMTS does not stay connected

[admiral_k]

As i had this problem after having updated to the new german O2 ROM 1.25.207.2, maybe it is of help for somebody else:

The problem was that everytime i activated DirectPush on my xda Trion, it connected just fine and synched my device.
But after some time (10-30 minutes), the data connection (GPRS or UMTS, no matter) dropped and could only be re-established after a soft reset of the whole device.

I GUESS that it could be the CAB: \Extended_ROM\PP_Suspend_Resume_Null.CAB in the extended ROM of the new O2 ROM.
Judging from the filename it is setting the following registry entry to NULL.
This MAYBE causes the problem described above.

Nevertheless, the fix for me was to enter the following in the registry:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ConnMgr\Plan ner\Settings]

"SuspendResume"="~GPRS!"

This is of course an old tweak from former Windows Mobile Versions - it works nevertheless also on the new Trion ROM - at least for me!

Has anybody else had the same experiences?
If so, maybe this is worth to put in the WIKI, as it took my some time to find this old tweak again somewhere.

Best regards - and have a good start into 2007!

Yes i had this in a similar way. It worked for some hours with some reconnects. But then a reconnection was not possible. So once or twice a day a reboot of the device was needed. I set the connection to alwayson to solve the reconnection problem. That works too. But I think this is now responsible for calling problems.
I have to do telephone calls twice to get a connection. Or in UMTS networks (mainly in one special location, could be an HSDPA problem) it happens, that the connection freeze. So I can't hear anything from the otherside and other way round also. I also can't close the connection.
Maybe that tweak from you is a better solution.

After having testing it for nearly a week now, all i can say is:

It works!

No disconnects, no failed reconnects, no calling problems.
Device runs even more stable as with the previous ROM - and, although this maybe is only misperception, it also runs faster!

So if you have problems with your GPRS/UMTS connections to stay connected - try this tweak!

Maybe somebody could add this to the Wiki?
