Root How to upgrade radio in my Desire?

Current version of my Desire's radio is 32.44.00.32U_5.09.05.30_2
I want to the upgrade it with the latest version. Is there any risk to do this? What benefits I can get after upgrading it? Will it increase the battery life?
 
1) Yes - if you make a mistake or its corrupt, phone bricked. As in really bricked.
2) You may get a slightly better signal*
3) You may get a slight;y increased battery life**

* You may get a slightly worse signal
**You may get a slightly reduced battery life
 
I've flashed mahy radios. Some of them did give me slightly better battery and signal but its not just version that makes difference. Its also network, country, atmospheric pressure... Just about everything is a variable so there are no guarantees.

My general rule is if it isn't broke, dont fix it.

I am s-off so I use fastboot flash radio radio.img to flash radios. If you are not s-off, it can be flashed via recovery but it adds a layer of software to go wrong.
 
:(

So, is it better to avoid upgrading? Did you upgrade yours? If yes, which version and how?


I've just flashed the latest radio. My Wifi and phone signal is improved very slightly. Battery life no difference. I only flashed because I was not getting as good a signal on dGB, than I used to on Oxygen. The latest radio (I was on a old Froyo radio) has improved this.
I used my netbook (linux) to flashed so that I have battery bakup in case of power fails during flash. But it literally take 10 seconds using fastboot.
 
I'd add a couple of tips:

* always check the md5 sum of a radio before flashing. As SUroot says, if it's corrupt you will wreck your phone, so it's worth a few seconds to ensure it isn't corrupt.

* fastboot flash if possible (i.e. if you are S-Off). In particular, do not try to flash from recovery if you are using a hboot or mtd with a cache partition less than about 30MB - installing from recovery will temporarily write the radio image to cache, so cache must be bigger than the image for this to work (and they are 26MB in size).

* if you flash from recovery (e.g. because you are S-On), then the procedure is flash, then reboot, then don't panic when it reboots itself a couple of times. The install only occurs when you reboot, and it will restart a couple of times during this - just leave it alone during this and don't interrupt it.

Having flashed radios both via recovery and fastboot, I have to say that fastboot is less stressful ;)
 
The radios are just that - radio firmware for the GSM Desire in flashable zip format. I specify GSM because they are not for CDMA handsets. The mirror site linked in the first post of that thread includes md5 sums for these (I think you can also find them from AdamG's site, but they aren't written in the first post itself).

RIL is a Radio Interface Layer. If you click on that link there is a description of what this is. The ones labelled "HM" are intended for Sense ROMs, "G" for AOSP. These can't brick your phone (an incompatible one could mess up reception, but easy to undo), but generally the RIL that's included with your ROM should be fine.
