Diamond 3G Radio not working after ROM flash

[mikethewolf]

I am hoping one of you bright lights on here can help me with this problem I've been having.

I have a HTC Diamond US 3G version. I purchased it unlocked, and recently flashed over the stock 1.93 ROM to one of the EnergyROM series. I had the usual problem of repeating hard resets because I didn't do a mtty.

So now I've done the mtty, and flashed with a stock 2.03 ROM and done a bunch of tweaking and reflashing. I'm currently using the Gen Y D2 R2 rev Y ROM. One problem that I haven't gotten to go away is that my 3G radio no longer works.

I can use my phone just fine (including data) when its set to GSM network mode, and automatic band selection. But when I change the network type to Auto, or WCDMA, i drop my cellular connection and nothing works. This has been going on for a month, I've gone through many different radios and ROMs and settings. I've gotten Rogers (my provider in Canada) to reset my network profile multiple times.

I would greatly appreciate any help that someone on here could give as I'd love to get back my 3G/HSPA capabilities!

You probably tried this but just in case you overlooked it.. Did you select 3G from your comm manager? There's a switch that you can toggle to switch between 3G on and off.

Hi,

Some ROMS work better with different RADIO versions... You can either check witch radio is best for your current ROM or try one of the latest Diamond Radios in the following list:

I'm using v1.09.25.23 and it works fine with my current ROM (netDrg 2.8) and had no problem with EnergyROM!

Hope this help!

Thanks for the help.

Yes when i turn on 3G, either on 'auto' mode or on WCDMA mode my phone gets dropped from the network.

Also I have tried many different RADIOs, and two ROMs now.

Some ROM can work out-of-the-box, other one you must try the combo of radio and rilphone. In your case you can search after rilphone and try Raphael rilphone or Blackstone. Raphael is better compatible with Diamond. Btw. I assume you already know your radio must support GSM850 (better use the one radio supported quad-band, you can always try the base radio first 1.00.25.05!)

Sadly I've tried alot of this as well

I have tried these radios;

1.00.25.05
1.00.25.06
1.14.25.05
1.00.25.08
1.09.25.23 (current)

I have also tried to use the Rogers rilphone.dll with my current radio, installed via Captain_Throwback's cab (http://forum.xda-developers.com/showthread.php?t=465419)

Should I be trying additional rilphones.dll?
Is it possibe that I broke my 3G by flashing a ROM? If I go back to my original stock ROM will i get it back?

[mikethewolf]

sadly nobody has any other ideas?

Try to rollback.. Reflash original ROM and keep your current radio. If 3G works then it's because of the other ROM you flashed. If it doesnt work after flashing original ROM, flash original radio. If it still doesnt work (hopefully it will) I think something would be wrong with your hardware then.

Maybe the ROM has hardset the WCDMA freq., like I do in mine.
Try changing this to AUTO in Settings --> Phone

OR Try flashing a radio, and afterwards install the corresponding rilphone.dll
