how can i reburn the radio update?

[Guest Pavelol]

well. i got my desire 2 weeks ago and 2-3 days ago i just rooted it by paul's guid and installed modaco custom room for HTC Desire with online Kitchen includes A2SD+ and radio update.

after rooting i had the generic rom and the gps worked fine but after i installed the custom room the gps stop working and cant find the satellites.

i try even the compass and still it doesn't give me the coordinates.

same with navigator.

so can i reupdate only the radio?

don't want to go back to the generic rom :\

Hi sorry for my english. You must flash older radio rom. Now check this ROM RADIO. Flash same like ROM, no wipe.

i just tryied to upgrade my radio update and in the recovery mode it's says: signatue verfication faild installation aborted.

i downloaded the zip file and changed the name to just "update" (no needed .zip cuz the file itself in zip) and move to the sd card and its always faild like i said above.

any ideas? :<
