USB weird connection problem :/

[itscanon]

Hello guys,

I have an I-mate JasJam .. a week ago i followed mrvanx's guide to successfully upgrade to schaps 3.30c . just two days ago my windows xp pro stopped recognizing my phone, it says generic USb in the device manager and sometimes it says HTC USB SYNC but with the exclamation mark .
I only managed to connect my phone with activesync 4.5 if "Enable advanced network functionality" IS ticked . and therefore windows recognize my phone as a Network adapter . And i can't flash my phone anymore as windows loses connection to the phone at the final step leaving the phone at the tri color screen :(
Tried and changed the cable but same problem .
Tried to use the microSD card flash technique to upgrade to schap's 3.54b and copied+renamed to HERMIMG.nbh to the root of my storage card but when i enter the bootloader mode i also end up with the tri color screen and the phone does nothing .
Been reading all over to solve this for the past 3 days but i can't figure out where the problem is :confused: :eek:

Is it possible that my phone got defected ? :rolleyes:

here are some info from my phone :
ROM version : Schap's 3.30c
ROM date : 05/15/07
Radio version : 1.41.00.10
Protocol version : 32.74.7020.18H
Herm100
SPL-2.10.olipro

thanks a lot

hi,

following tries:
-unselect/deactivate "Enable advanced network functionality"
-turn your Computer off and Phone on
-connect Phone with Computer
-switch PC on

Is a stable connection between phone and pc?

You can flash much with the attitude sspl in RUU Wapper.
