[Q] Omate TrueSmart change baseband freq ?

[Viperdk81]

Hallo, I bouth by mistake a 1900mhz TrueSmart and cant use 3g here in EU, so I was thinking maybe I can change the baseband freq to 2100mhz. I did abit of research and it seems that the MT6572/MT6166 is capable of running in both the 1900mhz and 2100mhz 3G-FDD baseband freq, but is it controlled by the firmware or does it use different pin's on the SoC, and if so can I rewire the pin's and the use the 2100mhz firmware ?
Hope someone can help me with this, thanks

I dunno if this helps but a while back i had mt6589 phone with tri band GSM and single band HSDPA, but then I changed the modem files in /system/etc/firmware (modem_***.img) and when I checked in Engineer Mode it changed into quad band GSM and Dual band HSDPA (like phone which modem file i pulled)...
It have more stable network signal and connection
I think flashing 2100MHz firmware is also works :good:

Hello could you help me with finding and flashing modem firmware - I have Callisto 300 (same specs as Omate's Truesmart, running omate KK now) I don't get 3g in US and in engineering mode it shows Euro, Japan and Aus and Aus1 - I'm assuming this is 2100 mhz watch and I need 1900 baseband in order to get 3g with at&t.
Thanks a lot

Change from 2100 to 1900?

I too would like to know if it's possible to change the modem frequency, but I have the EU version, but am in the US with AT&T. Is it possible to change to 1900mhz so I can have 3G?

Baseband Changed

Hi, I finally got 3g 2100 mhz on my 1900mhz
I flashed the 4.4 rom from http://forum.xda-developers.com/omate-truesmart/development/rom-omate-truesmart-ironman-firmware-t2998434
and Baseband file from https://drive.google.com/folderview?id=0Bz7sBdJpIWEgRm5MYnhEQmlTNDA&usp=drive_web&tid=0Bz7sBdJpIWEgOWoxNEVXWkZKbkk

then followed guide from gerhardo.

adb shell mount -o remount,rw /system
adb push .\1900Baseband\modem_1_wg_n.img /system/etc/firmware/modem_1_wg_n.img
adb shell chmod 644 system/etc/firmware/modem_1_wg_n.img
adb reboot

Change Baseband from 1900Mhz to 2100Mhz.

I have refleshed from my stock rom 1gb/8gb 1900Mhz to stock rom 2100Mhz (from needrom). 3g works fine now with 2100Mhz.

Fifine W9 1900->2100 3g?

I have refleshed from my stock rom 1gb/8gb 1900Mhz to stock rom 2100Mhz (from needrom). 3g works fine now with 2100Mhz.

I need the inverse. Do any of you still have your original 1900 Mhz baseband files for Kitkat 4.4.2? The google drive link in the post above is dead.
