Hi All,
is there anyway to determine what GSM frequency band a WM5 phone is currently using?
I would like to know if my WM5 device is using a 900 or 1800 MHz GSM band. The device is quad-band capable and the network I am on is dual-band 900/1800. I can't find any GSM hash codes to report the information and I've had a quick look through extended TAPI but can't see anything.
Building on from that is there anyway to force a WM5 device to only use 900 or 1800? i.e. the mobile would only report itself to the network as being 900 or 1800 capable...but not both.
Thanks, rhd
The physical hardware between these three models of phones are the same, yet they have slightly different radio ROM configurations set through firmware. My issue is that the 910c I am using has UMTS 850/1900/2100 MHz capabilities and I would like to use it on T-Mobile's 3G network which uses the UMTS 2100/1700 MHz. Has anyone tried to modify the frequency multiplier to substitute either the 850 or 1900 MHz for the 1700 MHz for use with T-Mobile?
Any solution yet?
I would like to be able to use 3G also with T-Mobile and have been looking endlessly, have you found a solution yet?
Don't expect such a solution - I've never heard of a successful radio ROM mod; all radio ROMs are issued by the OEM / manufacturer.
Have a look at the Qualcomm MSM6280 chipset datasheet - it seems the frequencies are probably hardcoded.
but how's talking about some qualcomm? HP has intel inside
Does anyone know Omnia7 supports WCDMA 850 (UMTS 850)?
I want know it's supported by hardware but disabled by software,
or does not have hardware capability of WCDMA 850.
My firmware is
PDA: I8700XXJK1
Phone: I8700DXJK1
CSC: I8700XSOJK1
I tried Diagnosis tool.
*#2263#
[2] WCDMA Band Preference
[1] WCDMA 850
then 'Band Pref:WCDMA 850' is displayed.
then tap [Back], WCDMA 850 is not selected, no changes.
I also choose [5] WCDMA 2100 then 'Band Pref:WCDMA 2100' is displayed,
and then tab [Back], now WCDMA IMT2000 is selected.
Why WCDMA 850 could not be selected?
I also tried,
*#1111#
11111111 then [Back] 8 times to enter test mode.
Then,
[3] UMTS RF NV
[1] RF NV READ
[1] WCDMA 2100 and [4] WCDMA 850
I found tx_comp_vs_freq_0 and _1 and [6] tx_lim_vs_freq is all ZERO.
Could you tell me these values is not all ZERO.
But I don't know WCDMA 850 works if these values set correctly...
I digged this topic quite extensively as there's no W-CDMA 2100 MHz in the country I live in.
Unfortunately, I came to a conclusion that like other Samsung (and other brands) phones, there will be two different hardware versions of the phone with different frequencies.
The Omnia 7 frequency range is the following:
GSM : 850/900/1800/1900 MHz
W-CDMA : 900/1900/2100 MHz
The corresponding W-CDMA 850 version would be the Focus.
Hope this helps.
I think it's software locked.
Last night i was playing with the tx_comp_vs_freq_0 values and i found a site giving the correct values for another old samsung phone (not with windows phone).
Unfortunately those values were couples of numbers, for example 27,23,-5,... and so on but the diagnostic tool only gives the possibility of inserting positive numbers (there are not the + and - symbols). However after i inserted the first two values i exited and.... now i have the 3g symbol. I does not work, but I bet that with correct values it can work. I'm in Mexico with my european Omnia 7. Here the 3g network is 850 wcdma only.

Oh whaw thanks for this info! Continue experimenting, maybe you'll finally get it working on 850 I really thought it's hardware-limited after everything I read on this subject...
Dealextreme sells an omnia 7 they claim to be WCDMA, might be worth a shot to get hold of someone that has it.
I think that the correct values are these ones.
Any suggestion on how to input them with the limited options we have?
4 tx_comp_vs_freq_0
0,11,21,27
26,20,9,0
-2,-1,2,7
11,12,8,7
5 tx_comp_vs_freq_1
-2,9,18,21
18,12,4,0
0,5,10,17
21,21,16,15
6 tx_lim_vs_freq
-1,0,2,2
1,0,0,0
0,1,2,4
4,5,7,7
i tride to change those numbers but i cant even put 1 number =( , someone have more luky .. or any other mehod to write the file ?
Hi,
I found OPO ONE + tutorial about adding LTE BAND in Qualcomm device and i want to make the same thing with my LG F320K.
I try to add GSM and 3G BAND by putting 844425030534016 in 1877 nv value with QSDM but when i start QPST software
downloader it didn't show me a change after a reboot. I try to change this value with QPST Software Downloader and i ve got this error: NV_IMEI_SV, that don't allow me to make the change.
I want to add LTE B20 800Mhz but cannot.
Can someone give me the Qcn backup of an international D802 or help me to activate all necessary network in my country (France)?
Thanks a lot, best regards.
844425030534016 with mzTool gave me:
[Bit_07] GSM DCS 1800 band
[Bit_08] GSM Extended GSM (E-GSM) band
[Bit_09] GSM Primary GSM (P-GSM) band
[Bit_18] GSM 750 band
[Bit_19] GSM 850 band
[Bit_20] GSM Railways GSM 900 Band
[Bit_21] GSM PCS 1900 band
[Bit_22] WCDMA Band I - EUROPE JAPAN & CHINA IMT 2100 band
[Bit_23] WCDMA Band II - US PCS 1900 band
[Bit_24] WCDMA Band III - EUROPE & CHINA DCS 1800 band
[Bit_26] WCDMA Band V - US 850 band
[Bit_48] WCDMA Band VII - EUROPE 2600 band
[Bit_49] WCDMA Band VIII - EUROPE & JAPAN 900 band
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?
