Had anyone who doesnt have the Global Version tried to change the LTE Band with the Snapdragon software tools? If you haven't heard or tried this just search Unlock LTE Bands in XDA main search. Because I'm think its going to be much cheaper to by the Chinese version that is like only 343USD for 6gb of RAM and 128 ROM and unlock the bands. Any thoughts? Thanks.
Changing the bands with QPST or QXDM can be done but it has no effect on functionality.
Some software will see these bands as unlocked but the phone itself can not make use of them. You might also run into some trouble on MIUI though custom roms seem more flexible with this.
At the moment there is no way to convert a CN (band restricted) model into a Global model (no band restrictions).
Hi, somebody has any news ?
for conversion(activate ) band 20 in Xiaomi Note 2 ?
thank you
This is very important topic I think. What I find really weird that the firmware files (modem) and rom are the same no matter which version you have...
On redmi note 3, kate and kenzo have different rom and different modem files. Its really weird here.

Hello,
I have an Vns-l23 from latin america and i want to change carrier but it has a 900MHz band and my model only support this bands.
4G: FDD B2(1900MHz)/B4(1700MHz)/B5(850MHz)/B7(2600MHz)/B28(700MHz)
But i've researched and models like vns L21,L22 and L31 support band 8 and i want to know if there is a way to have LTE in this band in my phone, maybe changing ROM or something similar.
I've found methods in google but are only for qualcomm processors and doesn't work.
I'm using Cyanogenmod ROM and i haven't tried if this band is compatible but i want to make sure that it works before i change carrier.
If someone confirm that this band work in CM or know how to make compatible, please solve my dude.
PD: excuse if i made mistakes, english is not my native language.
Thanks.
As far as i know, is this a hardware thing and cannot be "unlocked" via software. If the latin american modem does not come with lte 800 support, i think it is imposible to "unlock".
News? Is it possible?
Could anybody do it?
I suppose it is possible...
I had asians firmware was-lx2 but i need to use it in Argentina, with other band for 3g and 4g.
So i chanhed firmware to latinoamerican was-lx3.
I supposed it would unlock me the same frequencies that the p10 Lite in latinamerica is using qhen you buy it original, but at the moment (1 day) i think nothing happend.. i do not hace 3g nor 4g.
What do you think?
Hey guys -
So like many of you, I reflashed my two Yotas to the latest RU Lollipop and was wondering if there was another radio firmware file that might wake up the AT&T US LTE bands. Any thoughts? Has anyone tried flashing the different radios to see if you can get a 4G LTE signal stateside?
Thanks,
Rootdude
what upload/download speed do you have now?

I have HSPA+ on AT&T . Can you help us with US modem firmware for LTE?

HSPA+ can be sometimes very good - 3-15Mb/s - what is your speed at the moment? can you check through speedtest.net ?
At&t firmware
I have around 3.5 mbs to download and 0.6 uploaf. Too small comparing local 4G. So, can you help us?
I do not think you can change that easily, there's a thread talking about changing Radio Bands but the conclusion I got from the reading is that it does not work, at least with current "user" knowledge, YD206 is from China or HongKong, and some of those LTE Bands can work in Europe, not so much on the USA, the bands that USA telephone companies are very different than Europe or Asia, and as such YD206 IS NOT compatible with USA LTE bands. UMTS can have much higher upload speed than the ones you posted, so it might be your network problem, don't know if they are any better in LTE over your region.
Should be possible
Qualcomm 8974 supports all LTE bands. We just need proper modem firmware for US bands. Method in those threads definitely doesn't work since Qualcomm introduced some hidden filters inside firmware
BTW, there is lte_prefferedband file in the modem folder of Yota EFS. Does anyone know how to edit it?
That might be a anti-tampered code against our NV changes
Ok, I found out. For AT&T we need qcn file from Yotaphone 2, model 205. I don't know it such thing exist on the market but this reference says that it might be compatible with At&T.

interesting thing is that YD205 model was never launched, so it doesn't exist at all, unfortunately. The inquiries about future developments of this model were negative...
Hi guys, I found this post, but it is an old one from 2014, I want to know if it still work.

Will test soon
I'm wondering about this too and will be testing it this week.
I've acquired a WW version of ZE520KL and have tried to change the firmware to the JP version to
see if that adds any usable bands. As stated somewhere else it appears that the hardware differs from
TW, JP, other version to the WW and I ended up with no network connectivity; both sim and WiFi.
I will be posting again after trying the QPST trick, but would love to hear if somebody else had any
success adding bands to their ZenFone 3. (CDMA and LTE 19 band is what I'm particularly interested in)
Take a look at this thread to start with.
I'm interested in this as well but haven't had any luck.
Hi, I have a korean LG G6 G600L model. I am based in Germany and use the T-Mobile (DTAG) network. LTE Band 3 works but I would like to check the LTE band list on the device itself. Does somebody know the network test menu code for this specific device/network?
Additionally is it theoretically possible to exchange the modem driver to enable additional LTE bands (Band 20 in my case) ? Is it only possible with root?
Happy to test stuff on this device as I would really like to keep it and improve the LTE reception. I love the DAC btw.
Thanks.

Hello
Just a question
Do you think if i flash a different firmware (H870) in my mobile (G600L) i can receipt UMTS 900 ?
It will not help u to add WCDMA b8 900 to supported bands, because:
1. Korean submodels probably have no hardware antenna support for this band, which is totally unusable in Korea;
2. U will not be able to flash another submodel's stock to Korean models without root and some rom cooking preparations, flasher just restricts u to flash another submodel's stock;
3. In case u modify another submodel's stock enough to sucesfully flash it to Korean model, but without Korean kernel, modem and specific patches - it will probably softbrick ur device.

Thank you for your reply.
I will change my modele by another
So I can confirm that G600L is not only showing the bands but also work with them. Band20 and 3 successfully tested here in Germany. Now if it would be possible to configure VoLTE with T-Mobile or cross-flash the german firmware but still keep the DAC would be perfect for me...
Looks like the Korean version has the most international 4G LTE Bands. The rest of the models in Asia barely have any 4G LTE Bands. Not sure what is used with this. Is the Korean version a dual sim version as well? Anyone have a picture of the box of the Korean version? There is usually a sticker on there that shows which 4G LTE bands are supported on box
---------- Post added at 02:58 PM ---------- Previous post was at 02:54 PM ----------
One more question.. Anyone here that has the Korean version able to tell us if it comes pre-installed with facebook? Do not want a smartphone with Facebook preinstalled that can only be disabled and not uninstalled.

how did you bring up that menu with all the bands? I have the lg h870ds model with hifi dac and 64 gig, but I can't locate the LTE bands to turn them on
Try the same but with 870 instead of 600.

based on the listed 3g and lte bands, I can assume this will work fine on tmobile us? any downsides?
what for this code *#546368#*600#
and in this menu "field test" is missing..... any one help Please.
Hi, I'm new here. I have a question. is it possible to unlock b20 band on Xiaomi mi note 2? In Poland I need to use LTE 800 Mhz. I apologize for any mistakes but my English is not very good.
There are some ways on the internet for different Snapdragon devices and CPUs .
Never heard any Mi Note 2 user that he succeded doing such operation...
I guess you don't have the global version and need band 20 for LTE...
Maybe someone will come with a different and better answer, but as i know, you can unlock them in software but hardware does not support those additional bands that the Global version come with...
I tried to change the nvram parameters but to no avail
