[HTC Desire V] jp1980:
* disclaimer, I ‘am only new on android so this procedure might include flaws and perhaps unnecessary or stupid steps. There might be better ways although it worked for me. You have to reinstall your apps. Of course I ‘am not responsible if your device gets bricked. Pay notice you will have to reinstall you’re apps again and probably a redo a lot of settings. Backup your data well

Thanks to kingcedz who got me started.

This procedure will get your radio updated to version 1.06. (at least it did in my case)

If you have installed a custom ROM already you are unable to update the radio version. In my case I had symptoms that for example the Facebook app and Google play did work over 3G even at high speed, but internet browsing was impossible. The radio update solved this.

IT IS HIGHLY RECOMMANDABLE TO UPDATE THE RADIO ALSO. VERSION 1.04 DOESN’T WORK WELL ON SOME OPERATORS.

If you want to do so, we have to go through some drastic measures though. Pay notice again the result will be like a fresh install!

1.	Backup all data from your phone.

2.	If your bootloader locked, unlock it first.

a.	For this I ‘am referring to this topic: http://xdaforums.com/showthread.php?p=28172565#post28172565

Follow the ‘bootloader unlocking’ instructions first.

3.	Backup your system.

a.	Boot into fastboot (or you are already there!)

b.	Go to bootloader

c.	Go to recovery

d.	Choose ‘backup and restore’

e.	Choose ‘backup’

4.	Lock phone

a.	Boot into fast boot

b.	Connect USB

c.	With command prompt : “fastboot oem lock”

5.	Install original RUU

a.	Reboot system

b.	Connect USB

c.	Run original RUU.exe. In my case it was “RUU_PRIMO_DS_ICS_40A_HTCCN_CHS_CU_1.35.1402.1_Radio_1.04.34D.11_20.11.30.11U_release_256137_signed.exe”. Google will find you some downloads.

d.	Follow onscreen instructions.

6.	System will be rebooted. Follow setup instructions. Don’t bother too much with the settings, although make sure you set language to English and set up a WIFI if possible. That will be useful for downloading the update.

7.	Update OTA

a.	Go to settings >> about >> software updates >> check now

b.	If asked select to download the update.

c.	After downloading select ‘Install now’.

d.	This will take a while. When finished you can check your version in about >> software version. Baseband should be 1.06.34D.05_20.22.30.23U and ruu should be 1.59.401.1

8.	Unlock phone

a.	Boot into fastboot

b.	Connect USB

c.	Run “fastboot flash unlocktoken” unlock_code.bin

9.	Reinstall clockwork recovery

a.	Boot into fastboot

b.	Connect USB

c.	Run command “fastboot flash recovery recovery.img”

10.	Restore backup

a.	Boot into fastboot (or you are already there!)

b.	Go to bootloader

c.	Go to recovery

d.	Choose ‘backup and restore’

e.	Choose ‘restore’

f.	Choose backup image (check backup date to get correct one if you have multiple)

g.	Scroll all the way down until you see ‘yes’. Select ‘Yes’. (google must think if we get to this place we still are not sure what we are doing)

11.	To make WIFI and BT work if they don’t work.

a.	Follow step 9 of this procedure:

12.	Reboot!

a.	Set up your phone to your preferences

b.	Everything should be OK now. You have to reinstall you’re apps.

Enjoy!
