After lots of dead ends I finally found a solution, flash global QCN on the Chinese version of the phone.
1. Go here and go up to step 6 and STOP. Make sure you don't delete with ADB before you backup with QPST too (see step 2)
2. Go to QPST -> Start clients -> Software Download -> Backup --- Back up as QCN, this is your original is anything goes wrong.
2.5 Make sure you have your IMEI written somewhere.
3. Download QCN and XQCN + All you need for the guide , proceed with the guide until step 12 and then first restore the QCN, reboot -> restore edited XQCN, reboot
4. Enjoy LTE
5. Backup new QCN with working LTE.

Alternate method:
Use RF_MV_Manager to restore IMEI directly to the QCN file, youll need to use the QPST from that thread, the other one doesn't have RF_MV_Manager.
Restore only QCN, LTE fixed.
Bonus:
Using this guide, make sure you still have band 4, original value should be 2061584302303.

Is there a QCN or XQCN with all US LTE bands unlocked yet?

I don't think there will ever be one.
You can unlock all the bands you need with http://forum.xda-developers.com/redmi-note/general/unlock-lte-bands-step-step-xiaomi-mi-t3084774
If it doesn't work there might be a filter, which is a hardware mod.

Well I guess you'll find out if it worked when you get there.
If it doesn't it's probably hardware filter.

if not root can't?
@aried73 must be rooted
thanks I made everything as you wrote, LTE began to catch well! but now I established android 5.1.1 AOSP, I can establish CM13 and not lose the qcn control?
I still have the following issues after following the steps:
- 4Gs network are actually detected when doing network search, but it will be 3G after we select it anyway
- setting preferred mode to LTE Only will make things worse: can't search for network
- in 2nd sim 4G works fine
any help?
Edit: actually I also want to ask: should I first restore your QCN file (80DE5873_0), unmodified? (I did). What's the difference between XQCN and QCN
Hi just wanna ask if this tutorial actually are the method to repair IMEI for anyone that have invalid or blank IMEI after flash / upgrade from custom vendor ROM?
Mine updated from custom vendor ROM MIUI7 (version 7.1.9.0.0) to MIUI7 (7.3.2) the IMEI seems ok, both SIM have different IMEI, even after flash to MIUI8 dev, for unlocking bootloader purpose, the IMEI seems valid, still only SIM2 able to lock 4G.
P/S : Currently I'm on CM13 look like the IMEI still valid and okay and yet only SIM2 can do 4G,
BTW does the method above can be apply on CM13 or just under MIUI environment?
What you're doing here is flash default global qcn file.
If you got a phone with custom firmware it's probably the Chinese version and that's why LTE doesn't work.
@salzzz yes that right first qcn then xqcn, I don't know the default imei for the qcn so can't edit it, only with alternate method I posted after.
Which ROM and radio are you using?
Make sure you use adb commands from the guide to wipe everything related to radio.
@Kirk77777 flashing Roms has not affect on qcn.
@BaTaK_iCe like I said it flashes default global qcn, it will fix any issues with radio, whether it's Lte or imei. Works with any rom.
Basically like going back to global stock.
@ vkass
hello please say why on cm13 santoshi, and other customs, lte only on 2sim slot ?

It didn't work for you.
You need to follow the guide completely step by step, wiping with adb is crucial.
dd if=/dev/zero of=/dev/block/mmcblk0p13
dd if=/dev/zero of=/dev/block/mmcblk0p14
dd if=/dev/zero of=/dev/block/mmcblk0p16
reboot
Just restoring the QCN should give you LTE, but the IMEI will be different, that why you need to restore XQCN with your IMEI.
OR like I said in OP follow alternative method and edit IMEI in QCN directly.
It didn't work for you.
You need to follow the guide completely step by step, wiping with adb is crucial.
dd if=/dev/zero of=/dev/block/mmcblk0p13
dd if=/dev/zero of=/dev/block/mmcblk0p14
dd if=/dev/zero of=/dev/block/mmcblk0p16
reboot
I DO THIS, its not working to me, i`m sad ((
I have tried it again:
I can't install the QPST from alternative method link, so I followed "the guide" (restoring imei), followed that dd-fill-with-zero, restore QCN.
I managed to restore imei using QXDM, yet LTE is still not working (before & after I restore imei)
I'm on CM13 1807 by Santosh, some days ago there's a radio.zip in that thread, and I flashed it, dunno which version, but baseband shows -8976_GEN_PACK-3.53308.1.57464.1
I'm not sure about imei, too, first time I bought the phone it comes with same imei, only 1 imei on box (which matches both sim imeis),
Phone comes with 7.19 rom. forgot whether the LTE was working/not though; after I flashed global rom, I just check that LTE is detected in both SIM1/2, but only works in sim 2

I really don't know, maybe check phone settings at
*#*#4636#*#* and make sure it's on LTE for sim1.
As you can see it works for me, I also have same imei for both sims.
AFAIK the radio zip is for official cm, maybe backup your rom and try flashing stock MIUI just to see if it works.
hi, just wondering how come i dont get the option to use xqcn in qpst?? it only allows me to restore qcn
[edit] updated version of qpst allows xqcn.
But now I'm getting this error when i try to restore xQCN after QCN
"The ESN of the phone does not match the ESN of this file containing RF calibration data"
What should i do?
I'm also getting. "No space on device" error when i run these commands
dd if=/dev/zero of=/dev/block/mmcblk0p13
dd if=/dev/zero of=/dev/block/mmcblk0p14
dd if=/dev/zero of=/dev/block/mmcblk0p16
Need to tick "allow file esn mismatch", restore anyway.
The error doesn't really make sense as it is used to delete.
Maybe the process needs to be done on stock MIUI.
Btw do you execute them one by one?

according to this, it's just a false positive error, you can ignore it
@vkass LTE is on for sim 1 and 2 (if it isn't, it shouldn't have been detected when doing network search either)
Hopefully there'll be a solution for this soon. Btw, what's your baseband version?
hi i did a mistake by dialing *#*#4636#*#* and set the radio band to USA in my lenovo zuk z1 ...I live in INDIA.....Now the problem is it couldnt detect 2g as well as 3g in my both sim slots .........I dunno how to reset to default and i have tried soft and hard reset still the issue persist.....NOTE:i havent rooted my mobile......

i had done the same thing,
theres two ways to do this,
1} Go to lenovo service centre and tell them about the issue
or
2} DIY.
for resolving this i had to flash the stock files via pc.
I have unlocked the bootloader.
then i had to flash the stock files from pc
1) get this tool
http://forum.xda-developers.com/zuk-z1/orig-development/tool-toolzukz1eng0-0-3-mauronofrio-t3332563
2) download and install driver from above tool
3) Download stock rom using above tool.
4) boot phone into boot loader
5) connect to pc
6) unlock bootloader (this will factory reset the phone)
7) now again reboot to bootloader and flash stock rom by tool
8) now you are good to go!

Hello all,
I have been searching for a fix for VoLte on stock based custom roms. Whenever we UB, root and flash rom, there won't be any signs of VoLte except that Volte toggle (which won't work). Even *#*#4636*#*# > Volte provisioned flag is also not working.
Requirement:
Xperia XZ dual F8322
Stock VoLte available FTF.
Flashtool
**No idea about F8331**
Instructions:
Clean flash
Always take BACKUP
1.Clean flash any VoLte ftf, in my case i used F8332_41.3.A.2.99_1305-0131_R3E.ftf
2.Fastboot TWRP and kernel (created using rootkernel).
***For ExistenZ > extract kernel(boot_exz.img) out from patch zip,rename to boot.img and fastboot.***
3.Then fastboot this command>> fastboot format userdata
4.Flash the DRM fix, Magisk (14.5 for Existenz), and safetynet patch.
5.Then turn ON and setup phone. Then go to Network and Internet > Mobile Network >4G sim Access point names and create this APN.
Name:ims
APN:ims
APN type: ims
APN protocol :IPv4/IPv6
APN roaming protocol :IPv4/IPv6
Then save it. This apn won't be visible.
Then wait to see whether VoLte symbol appear or not. (Turn on/off airplane mode for checking)
If NOT, then do this,
Flash the attached ftf file or flash oem.sin file alone from ftf without any wipes and turn ON phone. This time phone will try to restart for enabling network settings (If not, change preferred network type of 4G sim to 2G and back to LTE)
This will enable VoLte for sure.
For Existenz users
After completing above steps and enabling VoLte, open Existenz patch zip using 7zip manager and delete existenz folder.
Then take out updater script,delete this line "package_extract_file("existenz/ftf/boot_exz.img", "/dev/block/bootdevice/by-name/boot");" and replace updater script from zip with this one.
Then flash Existenz patch without any wipes and reboot phone.
If you face theme selection error, then got to system>app>skin picker release and install that apk there itself, using any file manager (ES File Explorer).
Then for making VoLte stable, do these steps again. So that VoLte won't disappear ever.
Name:ims
APN:ims
APN type: ims
APN protocol :IPv4/IPv6
APN roaming protocol :IPv4/IPv6
I tested this method only on ExistenZ Rom usinf F8322 dual XZ.
So for other variants i am not sure and i am not responsible.

I try to instal VoLTE enabler in Magisk but don't work
Hey need help. My friends f8832 was on Oreo. He didn't like it so I reverted it by flashing stock FTF file. But only issue seems to be volte. It stopped working completely. Some modem issue or baseband I don't know. Could you help me out. How to do it? I flashed f8832 commenwealth of countries. From xperiafirmarews(some website) . I would highly appreciate your support
Got one of these used today, not sure if SIM2 ever worked to be honest. After downgrading to Nougat, installing TWRP and installing Oreo, I noticed that the second SIM cannot register to any network - although the SIM card is detected (with PIN prompt) and the appropriate network shows up in Settings if you search manually for networks. Tried RAT selection and Network Mode in the hidden menu, didn't do anything. Clean flashed back to Nougat, same thing. I know this is a known issue for the H990N but I haven't found anything for the DS. Anyone knows what's up?
Did you do the clean flash with LG UP and flash the complete kdz?
Which variant of the H990DS do you have (AME, TWN, ...) and what kdz did you use?
It might be a problem with your EFS or firmware partition. Did you flash any ROM that might have included these, overwriting your original EFS and firmware partitions?
I do some test on my H990DS to enable VoLTE for some carriers used in my country by editing some configuration files (rooted phone on oreo) and found out that if the configuration for VoLTE is not correct yet (meaning VoLTE does not work with the SIM cards of a certain carrier for which I am testing) it can lead to the same symptoms you have. In that case I have to restore EFS and firmware partitions from a backup taken beforehand to make the second SIM slot (in which I tested the card) work again.
I did do a clean flash multiple times, both with LGUP with uppercut as well as clean LGUP with the patch found here: https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222
I seem to have the AME variant since the other KDZs i tried would throw up the "not available to user" error. Until I figured out what that was about, I tried TWN and SG firmwares - v10a, v10b and v20a.
Outside of KDZs i only tried https://forum.xda-developers.com/v20/development/rom-h990ds-20a-ame-flashable-t3883897 , which didn't boot. I was not expecting such an issue, so I don't have backups of the EFI and firmware unfortunately. What are their partition names and what do they contain?
To add, the second SIM slot does have a correct IMEI.
*** Use this at your very own risk.
***Backup your persist.img. There is a guide to fix it if needed.
*** Backup your working modem. Sometimes it is as simple as restoring it if you lose signal.
*** When flashing, you must understand the difference between fastboot and fastbootd to avoid flashing errors.
*** Backup your files in a safe place.
*** Some users are reporting that the whole thing is not working and going on a blame streak. So if you're not quite ready, please don't attempt this.
Basic Instructions: "I will test again since some users are losing signal after flashing". There is a debate whether msm and update the tmobile firmware, or flash the global. Again this is a WIP.
MSM. Here is the thread.

---------------
Old Instructions
Here we go .....
This is fairly new and hasn't been tested so, proceed with caution. There are more knowledgable people here. This was just tested quick and it worked.
Requirements
1-Be on T-mobile firmware and update to the latest version. If you are bootloader unlocked, you mean not be able to take OTA's and you may need to reflash with MSM and update, then unlock the bootloader again. Thread Thanks @Some_Random_Username
2 - Unlock your bootloader.
3- --! IMPORTANT: Make a TWRP backup of your MODEM because we'll restore that later, why? because t-mobile sim doesn't work on the Global Modem. You can also back everything up in TWRP just in case.
If you have OTG, make the backup there so it is safe. You can restore the modem through TWRP with the OTG.
4-Backup your persist. Otherwise you may lose the fingerprint.
You'll need root.
Code:
adb shell
HTML:
su
Code:
dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img
Then
Code:
adb pull sdcard/persist.img
Then copy it from from Sdcard to a safe place
*** You may lose signal again if you update the global version. It is a WIP but keep your modem backed up!
With all the above:
It is simple. Download the global firmware and flash it through fastboot. Here is the thread
.. I tested with "10.5.5-GLOBAL-OnePlus8Oxygen_15.O.14" Thanks @mauronofrio
Reboot to fastboot
Unzip and flash-all
It will reboot to the global firmware. "Now you won't get cellphone signal"
Skip the setup and reboot to fastboot.
reboot to twrp, do not flash it.
Code:
fastboot boot twrp.img
link to twrp thread. . I used TWRP 3.3.1-2 Test by @mauronofrio
plug in the OTG or locate the backup and Restore the Modem" to get signal
Reboot and you'll have signal.
To root. you can flash the patched boot located in the sourceforge folder " Patched-Stock-Boot" on this thread
Code:
fastboot flash boot filename.img
You can also flash magisk in twrp. I prefer the patched boot.
Bonus: I am running the Nolimit magisk rom Thanks @xXx

For the global, we don't know until we get it, but @Some_Ghost checked with the euro and signal stays, so you can do the euro version instead of the global and still keep the the signal without reflashing your modem.
Does anybody have the modem backup I lost mine and can't find fastboot for tmobile
The EU modem dont fix it I just need tmobile modem if anyone can can someone give be the modem either tarp backup or .img file so I can use data

If you flash your modem backup with Euro firm it sticks throughout updates so far... It didn't work for me on global. You still need to restore your modem backup on either firmwares. Global so far modem doesn't stick after updates, euro so far, it stays after updates.

I fixed it with ota if you flash global do the enable and and dev settings I waited to install magisk. Ayer first boot put ota for global and it works because ota has modem in it and fastboot can't flash modem yet with bat file but I have no issues I have global modem and global ROM and from here on ota will work no need for modem
not really converting to Global then? this is just so you can use dev ROM, but since DEV rom hasnt come about there really is no reason to do this.

Ayer first boot put ota for global and it works because ota has modem in it and fastboot can't flash modem yet with bat file but I have no issues I have global modem and global ROM and from here on ota will work no need for modem

I will try this thanks ??
Does the Global ROM share the same 5G compatibility introduced in the new TMO ROM?

What? He used global ROM. Not a DEV ROM.

Thats what I'm saying, this is to flash rom, it not necessarily converting the phone to a global phone since it still need Tmobile Modem bin file in order to be function as a phone. If you take the phone outside the U.S it questionable if it works, that is why I say this is only for Dev Rom and in this case stock global rom but it is not a global phone.

Well check @ecompton59 's response. He was able to get things working.
The modem does work, just there is an issue with the fastboot flashing the modems. The TWRP restore of the modem is to get cell signal right away.
Here is what I did:
After I did what is in the first post in the thread:
I used oxygen updater to download the EU update and flashed it via "Local Upgrade" @Some_Ghost tested that as well.
There is signal. I believe that it may have flashed the modem "maybe", unlike fastboot.
While I was on the EU version, I downloaded the update for the global, and did a "Local Upgrade" again, and got signal.
I did all of this with Magisk being installed and after each "local upgrade, before reboot" I install Magisk on the "inactive slot, ota".
Technically speaking and don't quote me 100%, the first flash to the global is what gives issues with the sim, but that's the way to get the ability to do "local upgrade" because it is disabled on the t-mobile firmware.
Theoretically and I haven't tested.
Unlock bootloader >> Flash global "won't flash everything properly" = no signal
Global to another global or EU update >> will flash the modem >> signal will work "as it will properly flash everything"

again, this does not make it a global sim unlock phone, you are flashing a previous Tmobile Modem on top of a Global rom.

It at least we can run different firmwares on T-Mobile. You could try the global msm on T-Mobile and report back. As being sim unlocked depends on the bands enabled in other countries but should work with any sim.

is there different functionality between the tmobile modem and global modem firmware? I flashed the global rom and am using that with tmobile modem flashed through twrp. I haven't done a local update yet to get the global modem. if I do, what is the difference running that vs the tmobile modem? im in seattle using tmobile anyway.... would I see a difference in anything? speed? I had updated to the tmobile ota right before I flashed, they supposedly updated something with the modem in that update. im just wondering if there is a benefit to using the global modem or not. I definitely see the benefit in using he global rom though....lol

you'll be fine, my signal hasn't changed since flashing it remained the same as far as I can tell

Be happy that people actually take the time to experiment and work on things like this for the community so we can root and run different firmwares, kernels, and recoveries etc. At the least we aren't stuck on TMO firmware with lack of updates and missing features and as far as we can tell everything is working and odds are you aren't going to be using a T-Mobile SIM when going out of country anyway. Any issues will be ironed out when we cross that path I am sure ??
