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

and Baseband file from https://drive.google.com/folderview?id=0Bz7sBdJpIWEgRm5MYnhEQmlTNDA&usp=drive_web&tid=0Bz7sBdJpIWEgOWoxNEVXWkZKbkk

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

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 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.

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.

Believe me, that works on 850 mhz frecuency. Mexician users had no problem with telcel in that band
I have both a RM-801 and a RM-819, I just flashed 7.8 to my 801 with NaviFirm and the NCS. I was wondering if it was possible to use the 801 FW on the 819, as I don't see the 7.8 FW for the 819.
If this has already been asked and answered, please point me to the thread. I saw something about using 819 FW on a 801, but not vice versa.
Thanks!!
yes you can flash if rm is different but phone models are same
Thanks!

Dont know if roms all also band related..
Nokia Lumia 800 variants
RM-801 / 800 - Global - GSM 850/900/1800/1900 MHz, WCDMA (3G) Band I (2100), Band II (1900), Band VIII (900)
RM-819 / 800.1 - US - GSM 850/900/1800/1900 MHz, WCDMA (3G) Band I (2100), Band II (1900), Band V (850)
Well if it doesnt work just flash the original fw back.
Works. Already got like that and no problems with 3g or signal... so, go ahead and flash it!
My GF has a 801-819 from US, which ROM on navifirm is the generic, unbranded one?
Hi everyone,
I have the LG Optimus L90 D415 from T-mobile. I'm in Europe using a different carrier and I can only connect to 2G (EDGE). Following the instructions I found, I configured properly the APN and tried to change the radio to "Euro band" from the *#*#4636#*#* menu but when I press the option "Select radio band" I don't have any options to choose, just the title "Set GSM/UMTS band".
I didn't find any custom ROM to check if it changes. Can you please help me?
Thank you in advance.
It may be under the menu found via 3845#*415# ,
Theres radio settings to enable band 2100. Not sure if it will work without a new anntena in your phone. Tmobile US do not use full 2100 band but a cdma subset.
Failing that i think your wasting your time with roms. Try updating the firmware for your anntena. Perhaps the firmware from the 405 model but update firmeware with cation
Did u get it working ?

After enabled is it possible disable it?
hi
Did it work?
The T-Mobile version of the phone does not support UMTS (3g) on band 1 for the 2100 Mhz frequency as many European and other countries use, so that's most likely why there aren't any options, because nothing you could change would make a difference.
Help
Any solution for enabling WCDMA 2100 band 1 on LG-D415 ?
Hi, I have two major questions about this tablet.
1. How long should I expect for the root access?
2. Any info about the LTE version? LTE bands?
Thanks in advance!

After purchasing Xperia Z3 I am eying Z4 tablet as well. I wonder if they'll release LTE version for US market with AWS HSPA bands (1700/2100) that T mobile uses in addition to LTE bands.
Here
android-root-guide.com # tutorial # sony-xperia-z4-tablet-lte.html
(replace the " # " by "/", couldn't post the original link as a new user)
is a guide that claims root access to the Z4 LTE tablet can be gained by a one-click-method. I haven't tried it out yet (and don't really trust it).
Root access to the z4 tablet would definitely be very nice to have. Any reliable source is appreciated!
Get a TWRP

This website appears like a scam to me:
- same text for several devices one could come up with
- same "testimonials"
- the text touts a lollipo-upgrade for the Z4 tablet ???!!
You should get root this way:
1. Go to SONY developer world and obtain an unlock code for your Tablet
2. unlock via fastboot
3. get a TWRP-Recovery image for the Z4 (THAT is NOT available right now, building it my self seems very hard due to my limited experience)
4. Boot into Recovery and flash SuperSU.zip

we need a working recovery like twrp, thats correct... AndroPlus mentioned that the recovery for Z2 + Z4T stock kernel could work.
He will work on it as soon as he gets his Z4T.

LTE works with T-Mobile network (B3:1800/B7:2600/B20:800) in Germany.
Here's what gsmarena says about the bands:
2G bands GSM 850 / 900 / 1800 / 1900
3G bands HSDPA 850 / 900 / 1900 / 2100
4G bands LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 17(700), 20(800), 28(700), 40(2300)
Speed HSPA 42.2/5.76 Mbps, LTE Cat6 300/50 Mbps
GPRS/EDGE Up to 107/296 kbps
which is consistent with my observations.
We have root now (though i haven't tried it myself due to limited functionality of my tablet) Check this thread http://forum.xda-developers.com/z4-tablet/development/kernel-andropluskernel-v1-t3170689
