Is it possible to change the ROM without activesync?

[mugglesquop]

Hi, i have a T-Mobile MDA Compact III (UK), as original, and want to change it from WM5 to WM6, i have been reading through the forums, and havent heard anything from people being able to change it without a PC connection. I can charge off USB, but activesync doesnt find it (tried with known working cables, and different PCs). I have come to the conclusion that when i charge it in the car, its got broken (as mentioned on one of the threads).

So, is it possible to CID unlock/change the ROM from the Mico SD card?

Cheers,

You can update copying the new rom on the sd card and doing an hard reset. There is a thread about this.
