Hi,
Is there a tool similaire ton GSM Band switch working for WM2003?
I need to change the GSM freqeuncy to 1900 since i need to go in Canada with an European XDA 900/1800.
I know i can do it from the bootloader, but each time i change it i get a full reset of my device, not so great
The bandswitch tool will not make your phone a tri-band phone, it will be 100mhz off frequency when on 1900, but heres the link anyway.

Hi guys,
I flashed the rom on my phone and i have lost the 850mhz 3g band. It has been repalced with the 900mhz. Is thier a way i can make my phone connect to the 850mhz band?
did you flashed an original HTC ROM? if so, i suggest you to conact HTC
I just bought a T-Mobile Dash 3G and unlocked it. I'm trying for it to log onto a 850MHZ network but I can't find a way to force that band. It keeps logging unto the 1800MHS band.
The only options for Network Type are: GSM or WCDMA
And the only options for Band type are Euro band, US band, or Japan band.
Is there a way to enable more options like GSM(1900+850)+UMTS(1900+850)??
I bought an European Optimus 7 and it shows on the box "WCDMA 900/1900/2100, GSM850/900/1800/1900"
There's any way to put this phone to work on 3G WCDMA 850 networks at full speed?
Thanks
I own a Telus version of Optimus 7. My phone has the 900 3G band on it. I will tell you how to check whether your modem supports 850 or not. First, you open up the dialer and enter ##634#. This will install the MFG app, that will be accessible through your app list. The password that it asks is 277634#*#. Now you have access to the manufacturer test/setting menu. Proceed to the Engineer Menu, and then Modem Setting, followed by Band setting. There, you should see all the bands that are available, and WCMDA basically means UTMS or 3G. If you have the 850 band, it should be available in this menu. There are two other things you need to do before gaining access to this band, if available. But in order for me to continue, I need to know which carrier you plan to use this phone on. I am going to assume you want to use this in North America and you have already unlocked it. Let me know, and I shall help you further on making your phone functional for a 3G connection. BTW, I am typing this on my Optimus 7...the keyboard is seriously great, and if it wasn't for the loose buttons, I would have absolutely no regret over my purchase.
Thanks.
I saw here, there are these options available:
1.Automatic
2.WCDMA Only
3.GSM Only
4.WCDMA 850
5.WCDMA 1900
6.WCDMA 2100
7.GSM 850
8.GSM 900
9.GSM 1800
10.GSM 1900
11.WCDMA 900
Sorry for picking up this old thread again but there is no final answer on this.
The point is that I'm having the same problem, I have a european E900 and I can see the WCDMA 850 in the MFG settings. So is this working?
I'm going to Thailand next week and wanted to use True Move 3G which is on 850 Mhz.
Ok, just for the record - I am in Thailand now and the 850Mhz 3G Network from True Move is not working on the European E900.
Hope this helps for those who were looking for this answer.
Hello. I have a Xiaomi Redmi 2 2014811 subversion which doesn't have the 850 GSM band that I need in the rural area where I live.
I have seen that the submodel 2014819 (Brazil) has this band and I would like to know if is possible to change the baseband by flashing any software.
In other words: Are submodels 2014811, 2014819 the same hardware with different radio/modem partition softwares or have they different hardwares?
I have seen that with other mobiles like Moto E 2015 is possible to change the region of the baseband by software:
http://forum.xda-developers.com/moto-e-2015/help/question-models-bands-t3163453
Thanks
I hope someone can help you with this
Hi, I'm Brazilian and got the HM2014819, as soon as I get the partition table I will upload it for you TO TRY of course after a Nandroid Backup by you. I will upload if the size match with my data plan :good:
Well, I don't know if you will can successfully flash it, and if it will work.
Going to dump the modem here in a .img that you can flash or make a flash zip
Thanks Lennoard, but I think is not a modem issue. I am on the way to Unlock the GSM bands in the Qualcomm, if it would be possible.
I have followed all the steps in
- Unlocking Basebands on MI4 (http://forum.xda-developers.com/mi-4/general/unlocking-basebands-mi4-t2879685)
- Unlock all bands of your Qualcomm device! Use your phone globally! No bs! (http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269)
- [Q & A] how can i enable qualcom diagnostic mode? SOLVED (http://en.miui.com/thread-100458-1-1.html)
Now, if I read the NV_RF_BC_CONFIG_I (#1877) from phone, the value is changed and all GSM and WCDMA bands are enabled, included the GSM 850 MHz band.
But I cannot connect to any GSM band and doesn't recognize any GSM provider in the area.
Bad luck
Anybody has tried this way with success?
Thanks
Anybody changed the basebands of a xiaomi redmi 2 in the qualcomm way with success?
I've tried the Qualcomm method and so far it's not working. Whenever I tried to add GSM/WCDMA bands, my phone keeps restarting. But, I can confirm that I can disable bands. When I tried to add LTE bands 5(850mhz) and 28(700mhz), the phone didn't restart but after disabling all other LTE bands, I'm quite sure the phone couldn't detect those bands. I don't think I can enable it because well... someone with an OPO couldn't... and 700mhz is just really low...
I don't know what's causing my phone to restart everytime I've added additional bands. What rom and you using? I'm using resurrection remix.

Thanks. Now I doesn't feel so lonely.
I did the changes of NV with MIUI v7 installed in the phone and indeed, the changes are still present and the mobile works exactly like before the changes. I read the NV and the bands are enabled, but still doesn't connect to any different bands than before.
It is strange the behaviour you get with a different rom. The NVs should be not affected by the ROM, it isn't?
Which submodel of redmi 2 do you have? Is possible that different hardware or antennas could be assembled in the different submodels of this mobile?
Thanks

I'm using 2014813, I wanted to add 900mhz wcdma which 2014811 has, but I chose 2014813 because it supported more lte frequencies that my carrier uses. There's also some lte frequencies that both models don't support which I tried to add.
I'll try to add bands with miui tomorrow.

I've flashed miui. So far instead of my phone restarting after trying to connect, the radio keeps turning off and on.
Ups! What a different behaviour! Is it maybe because you are changing the NVs for 4G/LTE? I only enabled all the 2G and WCDMA (3G) Bands and didn't changed anything in the 4G and my phone just works and detects networks exactly like before, nothing looked like to change.

Have only messed with 2G/3G so far, adding 900mhz wcdma is still causing issues for me. I can enable 850mhz gsm but I don't know if it would actually work because no carrier uses 850mhz gsm here.
What are the steps you did to try to get 850mhz gsm to work?

According to the specs:
HM2014813 Is "China Mobile 4G Dual-Sim Version". It Supports These Network Bands/Frequencies:
4G Network : TDD-LTE (B38 / B39 / B40 / B41: 2555-2655 MHz); FDD-LTE (B3 / B7)
3G Network : TD-SCDMA (1900 / 2100 MHz); WCDMA (850 /1900 / 2100 MHz)
2G network : GSM (900 / 1800 / 1900 MHz)
The phone should have an antenna capable to work at 900 MHz, because it uses this frequency for GSM, then, adding support for WCDMA 900 MHz is not a radio issue but a logic one. Doesn't it?

I basicaly followed this steps:
Unlock all bands of your Qualcomm device! Use your phone globally! No bs!
http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269
I enabled all the bands using the NV calculator and saved the value that after restarting is still stored, but nothing changed. The phone is working since this (2 weeks ago) exactly like before, no any strange behaviour.
Then... still there are no signs of anybody saying that this method works with this model.
But I don't loose the faith

I don't know if antenna placement is different but the modem between the sub models aren't compatible with each other. This is what I would need to do to get any signal at all.
With mztool, try selecting only 850mhz gsm and edit the RF BC Config as well as the Band Preference values and see what happens.
I think I might need to conclude that I have not been able to get 900 mhz wcdma working on my 2014813 despite the 2014811 having it. Also with LTE I haven't been able to unlock any additional bands.
Hii all, I'm interested with this topic too.
I would like to add LTE band40 which 2014813 has.
What happen if i flash baseband from rom 2014813 to 2014811 ?
Here my baseband radio on crdroid [imgur.com/wgrMqPk]

Flashing the 2014813 modem on your 2014811 would probably lose your signal. This or this is what would need to be done if you have a 2014813 and flashed a rom with a 2014811 modem in it.
Happy new year to you, all. @MagMar I already try to flash 2014813 modem to my 2014811..it is no signal but imei n baseband are find..but my 4g card display correctly at lte discovery..so maybe you can share nv config value (like nv 1877, 6828 n 2others) that 2014813 have...n i think lte freq dependent with 3g freq also

While I've flashed 2014811, my phone does recognise the imei and baseband but it'll tell me that I have no service. Both models do share some of the same bands so it should be able to connect assuming both models have a supported band to the carrier. This is why I think that flashing different modems and editing the NVs won't work.

Mine is 2014813(running a mokee 60.1 rom), too. I've tried to add wcdma 900 through changing the four nv values specified by the mztool and fdd b1&b8 through changing the lte_bc_config nv value. So far everything seems to be fine. While, I not sure whether those changes are successful or not. Do you have any idea how to confirm that those added bands are working or not?
