[Q] Flashing Gingerbread with Froyo MODEM ROMs

Hello, i live in Argentina and here UMTS/3G networks use the 850 Mhz band, as you know this is different to the 3G bands in use in Europe/Asia/Brasil, So far i haven't seen any GingerBread ROMs for the Galaxy Ace that use that Band.
I was wondering if using ODIN i could flash BOOT/PDA/CSC and leave the old Froyo MODEM ROM installed.
There is a brazilian modem working on your band, 850 mhz. Look this post

Nope, that won't work, Brazil uses the 2100 Mhz band,
I've already tried that ROM with no luck, had to return my phone.

[Q] S3 I9305 change baseband to AWS 1700?

Is there is a way to flash change the modem for my S3 I9305 (international unlocked) so that it works with Wind mobile which uses the 1700 band?
Is there a custom ROM for this, or a modem rom I can flash to make this happen?
Hey Max,
what model do you have?
i9300-international
or the i9305 ?
Anyways both models doesn't and will not support the 1700 band as it's a hardware and not software.
sorry mate..

I thought the modems were just software controlled for the bands?
The modem can affect your signal, but only as long as your device has the required hardware.
I mean, you can't control the TV from your S3 as you don't have the IR like the S4 does

Yes it will work, you may just need to flash a new modem adapted to Canadian network frequencies. Read this and that.
