AT&T Defy No 3G

[deadsky671]

Alright... so I cannot for the life of me find a fix for this anywhere. At least, one that works. I've been messing with Roms on the end-user side for a while without errors and this is the first phone I've had a problem with.

I cannot pick up 3G anywhere, baseband switcher says it's damaged, I've tried numerous Roms and I've tried any fix I could get a hold of... Tried deleting bp_nvm_default... here's what I have on my phone:

MIUI Pikachu Edition
Model: MB525 (Red)
Android: 2.3.7
Baseband Version: EPU93_U_00.59.01
Kernel: 2.6.32.9-gb08c3c8 (Fri Jun 3 2011)
Build: MIUI-2.Xy

I would most definitely appreciate any help. Some additional info:
I'm with AT&T out of the California area in Sacramento. I've tried towers within 100 miles to no avail.
Again, any help is highly appreciated... if you need any contact info let me know.

-Chris

why not try flashing a stock sbf(to fix the baseband) and install ROM again?
and also, did you try the 3g fixes in the development forum? Try flashing the one specific to your region and you should get 3g back

There isn't one for AT&T basebands..... I've tried all the US basebands available (they're all TMobile). I tried reflashing the sbf
And then the Rom. Doesn't work.

Is the problem rom specific or does the problem occur in stock rom as well

Not ROM specific. It was working before flash...

Try flashing this SBF, containing radio files for T-Mobile US. UnRAR and flash using RSDLite.
This will not change your Rom, just radio files.

Look here for more info.

I know, there is no SBF available for AT&T to extract radio files from and AT-T and T-Mobile use the same bands frequencies.

So, the problem occurs even after stock sbf flashing? I haven't checked, but is there a sbf of your provider available? After flashing that, 3g should work as it did out of box. Also, try ticking ti blank flash option when flashing the sbf. That should solve it I guess.

I cant find an AT&T SBF

 

[thekguy]

Which sbf are you currently flashing? And have you tried the blank flash option? Also, try a different Tmobile sbf than the one you are using currently
