WARNING: HP2210 and TTN3 Restore Issue

I was recently in a position where I had to hard-reset my 2210. No problem, I thought, as I religiously back up my system to both SD card and via the Activesync backup tool onto the desktop.

However, after restoring via either method, upon soft-reset the 2210 would hang. After doing some research and coming up with a blank I thought the only option was a complete rebuild from scratch.

However, I finally came across the following thread (msg#13):
http://www.totalpda.co.uk/forum/showthread.php?s=592c9d12a40c8e9cb18d5fece47dc884&t=1614&page=2&pp=10

This describes the symtpoms I was experiencing, and the solution (interestingly another issue apparently caused by TomToms ttbtdev.dll replacing the default BtCeIf.dll).

If only I had known this before I did my last backup!

All was not lost however, as it IS possible to use the information in this thread to recover a system where the ttbtdev.dll is active.

Here is how I did it:
- after the hard-reset, I restored from the most recent backup - but did not soft-reset
- I renamed \Windows\ttdtdev.dll to \Windows\ttbtdev.dll.old
- I copied \Windows\BtCeIf.dll to \Windows\ttbtdev.dll
- A subsequent soft-reset did not hang the 2210

I used the free PHM Registry Editor to reset the appropriate registry key and performed another soft-reset. Then deleted ttbtdev.dll and renamed ttbtdev.dll.old back to ttbtdev.dll.

Last thing, I took another full backup!

This has been discussed many many times on this forum before - I'm suprised you didn't find anything here.

I might even be as bold as to say that I was one of the first to discover the fix to this problem Wink

Alternative, possibly easier, way of doing it is when you do the restore, simple untick ttbtdev.dll from the list of files being restored. Works fine then.

A much easier solution is to use Sprite back-up, which only costs 10 dollars for the upgrade after the free 30 day trial - the latest version is 3.1.4. This overcomes the problem which has had many threads on this and the Sprite forum.

nej - apologies for the repeated post Embarassed

. I am not a regular on this forum (can you tell?) and not finding anything here (I did look - honest) wanted to pass on my findings in case they were helpful to someone else.
I'll look harder in future before posting.

SteveW - I prefer the 'cheap' solution to the 'easy' one Wink

I believe the easiest way to restore if a full restore hangs the machine is to turn off Bluetooth, restore everything except \Windows\ttbtdev.dll, soft reset, install a registry editor, find the HKEY_LOCAL_MACHINE\Drivers\BuiltIn\SerialN key (where N is the COM port number of your outgoing Bluetooth serial port) and change the DLL value in that key from ttbtdev.dll to BtCeIf.dll

If you're not sure you've found the right SerialN key go through them all and change any DLL values that are ttbtdev.dll to BtCeIf.dll - there should only be one.

That leaves you with a machine where the TomTom Bluetooth driver is not hooked into the Bluetooth stack. If you don't like this behaviour, turn off Bluetooth, soft reset, go to Start Menu, Settings, System tab, Remove Programs, tap on TomTom ~ GPS and tap remove, then download and install TomTom GPS 3.07.

TomTom GPS 3.07 is half the fix to this issue - the other half is to buy the upgrade to Sprite Backup 3, and install the latest version of Sprite Backup (3.1.4 at this time).

Those instructions were for hangs when restoring using iPAQ Backup or older versions of Sprite Backup.

For ActiveSync restores, see here. I think, unfortunately, that if you're seeing the problem in that thread, your backup file is useless, and the only option is to set things up again from scratch.
