Hi there,

My X7500 internal GPS seems to have a defect. The slightest touch makes it lose it's fix as if there's a loose contact. My x7500 is SuperCID (IMEI-Check) and has OliPRO hardSPL.

Is there a way to downgrade to the latest WM5 version prior to me sending it back to HTC for repair?

Cheers

FYI

With one exception. When going back to WM6 I lost my radio 1.45 in the process. I was stuck at 1.38, and upping to WM6 did not bring back the later radio stack.

*Update* Olipor's unlocker nicely took care of that. I now actually managed to combine rom 2.20 and radio 1.47. Thx Olipro for a helluva job building the unlocker! The only thing now is to see whether radio 1.47 improves some of the GPS reception. If not, it's down to WM5 and back to HTC with this puppy.

I have the HTC Generic X7500 (originally Dutch). I used RUU_Athena_HTC_WWE_1.25.405.2_1.38.00.00_Ship.exe to go back to WM5, but the prerequisite is OliPRO *and* superCID.

OliPRO's unlocker will do that for you and gets you these two prerequisites.
