[Q] HTC Desire freezes when switching from 3G to 2G

Hello out there,
since I wiped my phone and updated to the most recent CyanogenMod 7 build (#262), my problem regularly freezes when switching from 3G to 2G mode. The only thing to get the device running again is to remove the battery and reinsert it again. If i'm still in an area or room with only 2G coverage, the phone freezes soon after boot-up.

Help or advice would be greatly appreciated!

Thanks in advance,
toco

My phone:
HTC Desire (GSM)
PVT1 S-OFF
RADIO-5.17.05.23

CyanogenMod 7 20120225-NIGHTLY
Android ver. 2.3.7, kernel 2.6.37.6

What I'd do in this order:

1) stop using nightlies
2) change kernel
3) change radio

There was this guy whose phone froze every time he was in space with low or no 3G coverage, and I think changing kernel from snq's to some other solved it for him.

Thanks for your quick response!

Ok, I appreciate your advice. If the problem keeps occurring I will switch back to the latest stable.

But, still something strange about it: I had absolutely no problem the first weeks i was using this nightly (262 was since November 2011 the latest nightly until today), the problem started to occur from one day to the other.
I am using the radio version since probably half a year or even more, without any problems.
Also, 262 was reported (cyanogenmod forums, other forums) to be very stable on the Desire, almost no people reported having problems with it. That's why i decided to update to build 262. I for my part am suspecting a software being the cause for the freezes, but i have no clue which one.. I even checked the system logs.

As for the kernel: Call me a noob, but how do i change the kernel? I know how to root devices, flash recoveries and roms, but how can i change the kernel directly?

Greetings,
toco

Kernel is flashed the same way as roms are. Make sure you use a correct one, manU 2.1 is probably the most popular of those which will work on cyanogenmod.

Alright, one more thing: If I change the kernel to let's say Manu 2.1 - how can I switch back to the original CM7 kernel again? Just by reinstalling the CM7 ROM?

Thanks!

Wait, if I set it to WCDMA only I can only access data services when in a 3G covered area, right? Thats not optimal either because i'm regularily visiting my parents on weekends, where only 2G coverage is available. Also in some buildings (esp. cellars) here in the city there is only 2G coverage.

Yeah, but it can solve the issue, I get it intermittently sometimes too but after a reboot or two its usually fine.

I would have written you a PM but as I'm not yet allowed to (too few xda posts) I have to put the question here: What happens on May 7th (your signature)? Because i'm looking for an adequate successor to my Desire (~3,7" display) as well.
