[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] Thl W8 Basebands

Hello all!
I bought a THL W8 in Argentina, and I noticied that it works ok in GSM (QUAD BAND) but in WCDMA it only works in 850/2100.
I just ask if there is any baseband flasheable zip to enable 850/1900 instead of 850/2100 knowing that maybe its included in the hardware but capped by software baseband.
Thanks!!!

X10a configured as X10i Working bands for 3G

Hi there, Could anyone tell me why my phone is configured as x10i bands? as the service menu says:
Working band/s:
GSM850, GSM900, GSM1800, GSM1900
UMTS_BC1, UMTS_BC4, UMTS_BC8
Well, this happened after flashing my x10a from 2.1.update-1 to 2.3.3, I don't know how to reconfigure the bands but I think is something related to the Trim Area partition because I flashed several generic roms such as:
-x10a (2.1.update-1 - 2.3.3)
-x10i (1.6 - 2.1.update-1 - 2.3.3)
Then the results are the same x10a still configured as x10i's working bands for 3G.

[Q] LTE Bands G850Y

Hi guys. I've a question. There's a way to unlock LTE bands on g850Y? I've bought my phone in Chile, but in Argentina LTE doesn't work on the same frec.
On theory, Panama's ROM for G850Y should work in Argentina's LTE frecuency, (band but i'm not really sure to flash, and i'm not sure if i'm doing something stupid and end up with a soft brick.
If that's possible, could someone explain the steps for flashing? (If i have to do a complete flash, or just modem.bin.. etc)
I need a ROM that get's BAND 4 AWS.. is any of this possible?
Thanks!
Same here
I have the same problem, if anyone can help please.
