[Desire Q&A, Help & Troubleshooting] wojtal:
I've been trying to install any ROM on Desire. The problem was it either didn't boot or did but here's another problem.

Successfully installed Supernova. Booted (and followed the instructions), installed some apps and... It keeps doing random freezes. Phone just stopped working and, after around minute, changed the screen to the HTC splash. Now it won't boot until I pull the battery for a few minutes.

Logcat doesn't show (imho) anything that can help...

...and here the phone goes into HTC splash.

Edit: And the second log.

Here the phone resets itself and isn't booting.

What's important, this phone was working properly without the sd-ext partition. SD card is 8GB Class 4. Is this card too slow for my Desire?
