[Q] FroYo & Desire reboots on its own

[Guest -Will-]

Hello,

All started when my Desire was updated to FroYo OTA !

I had some random reboot when using internet browser, Nav, Maps, etc...

I tried to install another ROM by re-installing 2.1 with HBOOT 0.80, rooting it with Unrevoked, wipe all that I could, and install another official 2.2 with radio found here, install Advanced Task Killer, Smooth Calendar and Astro file viewer.

I have re-installed a clear 2.2 rom (2.09.405.8 CL218634 & Radio 5.09.00.20) without any application to prevent from compatibility issues, but it is still the same.

I don't know what to do... and don't want to get 2.1 as it should be fine with 2.2.

I tried to do it with and without the gel case, as the phone was hot the first times.

And sometimes, it reboot, and stay on the first HTC screen, before the "quetly brillant" animation.

Anyone could help me or give me a way to use Nav without reboot after 2 or 3 min ?
