I5800XXJPU on I5801 3G

Hi,
I'm on Vodafone India. I have flashed I5800XXJPU on the I5801 and it works great. I recently activated 3G on the phone but it just doesn't seem to connect..!! Is it a problem with the radio or something, like the radio not compatible for 3G in India??
Thanks!!

Flash an asian ROM. I think it's called XXJp4 or something like that and you can also contact vodafone for your APN details.

If you want 3g and also want great features of other countries firmwares I think I remember Darekills has a work around try contacting him

I think this problem is faced by vodafone users and it has to do with modem

Why did you create 2 threads for the same issue?
Anyways, what data network mode did you select? It should be LTE/WCDMA/GSM Auto connect.

Thanks !

Maybe you can flash your old radio from previous rom where LTE works? Did you try flashing roms before it happened?
