Hi All,
Recently Moto has pushed 7.1.1 update for Moto z. But as always, update is not flawless. It seems like LTE Band 5 and Band 40 is not working after the update. It works fine on Band 3 though.
If you guys have the same issue of 4g, kindly do the following and post the band number (or LTE frequency) on which it is not connecting.
1. Install the app LTE Discovery
2. Remove sim tray and open LTE Discovery.
On right top box, you will see LTE information as shown in below screenshot.

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
3. Now insert the simtray with your sim in slot 1. You will see the app picking up information. (Note: be quick to take a screenshot or remember the band number. It will disconnect shortly. If it disconnects before you could get the band information, repeat the steps 2 and 3) If you have successfully taken a screenshot, it should look like the below pic.
4. Now post the Band which is not working in your phone and the Band that are working (If the Band is working, it should not disconnect immediately) along with your software channel.
In my case, Band 3 is working and Band 5 and 40 are not working. Mine is RETIN.

Same issue since 7.1.1
Hi,
after installing 7.1.1 this morning it seems i got the same issues.
My little network strength display triangle shows a very small x on the right side, and no mobile data flow.
If connected to HSDPA everyting works fine, as well phone calls are ok (no phone via LTE here).
Talking to a technitian of my provider (Hutchison 3 Austria) he told me he could monitor my phone trying to connect,
changing between 4G and 3G but no data flow.
Now, LTE Discovery shows my Z jumps between Band 1 and 3, but not establishing any stable connection.
Softwarechannel is 'reteu'
Talking to a Motorola online help chat they just told me to send my Z in for repairing (after it didnt work in safe mode as well).
Now, what to do?
P.S.: its already my 2nd Z, as my first one crashed its SW and after restart had excellent 4G internet, but no more phone working, as it didnt switch back to HSDPA or 3G
4G/LTE issue after 7.1.1. update - Moto Z
Hi,
This LTE / 4G issue is the same on my Moto Z too after the 7.1.1. update.
Only 4G/LTE not works, 3G/2G works fine... but who use those?
I've contactet the US and the Europe Support of Motorola too.
And after reading a lot of topics about this problem, I said them, to make a fix for this, because its a global issue, and lot of people just can't use it's 4G/LTE mobile network.
They told me to go to my service provider. I did it, we tried my SIM card in other mobile brands, 4G works perfectly, only the Moto Z can't connect to 4G/LTE.
As U guys said, yes the LTE Bands are the problem on our region.
For example, my case is the following:
Region: Hungary
Service provider: Telenor
Bands that are have to be enabled/supported on this region with this service provider: B3, B7, B20.
I tried the LTE Discovery app too, and I saw that my phone trying to connect to the B20 and B3 but not establishing any stable connection.
At the moment I really don't know what can I do.

Hi, thanks for sharing.. Moto customer care is virtually useless. I tried contacting their technical team with no success. My best guess is, Moto screwed up with their modem configuration. In RETIN device, B5 and B40 are not working. I am guessing B5 and B40 is not available in Europe. B3 (which is a common band in Europe) is working fine in RETIN.
If they find out the issue, they can fix within a week. Probably flashing modem (NON-HLOS.bin - was the modem file in Moto firmware, I am not sure if they are still using the same name. It's been a while since I did these things.) from an old firmware should also fix this issue..
I would suggest you to wait till the next update, I am still trying to point this issue our to Moto tech team.

Hi, I am from India. After the update, my phone worked fine.. I was very happy, but I came to my hometown for the weekend. On my way, signal dropped. And since then I am managing with wifi. My carrier is a 4g only carrier. I don't have any other number too. I really hope to get signal back in the place where I work. (Band 3 seems to be working in RETIN device).
I am quite sure this is a minor bug on the technical implementation front. Moto can fix it in a week, if they come to know about the issue and it's seriousness. Being a well established brand, this is definitely not a thing you wanna do. It is a blunder by Lenovo owned Moto.

The same problem in Poland. No internet on B3/B20. LTE at B1 works (other provider).
Is there anyone in the USA that is experiencing these LTE issues since installing 7.1.1, or is this purely an international issue? So far since installing 7.1.1 the only problems I've encountered were screen freeze/reboot. But as far as my LTE strength with Verizon Wireless goes, everything is status quo.
I am in the USA, using att, and after updating to 7.1.1 I had the phone set to 3G only here and it was effectively stuck with no option to enable LTE. A network reset fixed that and now I am ONLY on LTE and often it seems to lose the signal. I will try to run the diagnostic tool today. Seems it is a problem on Lenovo side for sure.
Same issue for me in Hungary (B7 connects well in the downtown area, but suburbs only has B3 and B20, those don't have any data connection at all).
I started a thread on the Lenovo forums about this, and many users confirmed, but still not reply from any official Moto account. I also tried the Moto UK support by email, and they said if factory reset doesn't work (no it doesn't), i should send the phone in for repairs. Since my phone is from Germany, that would be quite a hassle
Has anybody tried to downgrade? For RETEU models there is a 6.0.1 fw version available that would be installed via mfastboot. Or maybe just the radio modem...?

Don't try to downgrade to M, it will brick your device because the bootloader has changed from M to N. You can flash the RETBR N firmware via fastboot or RSD-lite. This is the only way to revert to stock 7.1.1 for RETEU devices. The softwarechannel changes automatically into RETEU after flashing and, once booted, you can take several OTAs until 7.1.1.

If you had issues with 7.1.1 you could stay with the latest 7.0, witch is NPLS25.86-30-12 and don't accept the 7.1.1 OTA.
I have the Moto Z force from verizon and after 7.1.1 i can not connecto to LTE 4g,
I'm using this phone with T -Mobile, but i was working fine before the update..
Any news?
Thanks
Band 7 and 8 missing
Getting Band 1,3 and 20 here in Czech Republic with Vodafone.
Band 7 and 8 are missing, as well as the complete absence of LTE-banner, enchanced LTe and VoLTE.
Been using LTE-discovery-app to log, as well as a brief switch of provider (Telenor) to confirm. Have also reported in the Lenovo-forum.
mirrormurr
This is still an ongoing issue for me. I guess we just live with it dropping the connection and not having full LTE support until the next update, anyone who had their device "serviced" have any better luck?
Well, I ended up sending mine off for service and I am on 7.1.1 from the factory on retus.
My problems seem to be fixed. I'm still pretty salty about this and will likely wait eons before Oreo if it ever drops.

Hello,
Are there any users with Redmi note 3 Pro / Snapdragon version that have issues like no 4G or LTE connectivity while using sim1?
this has worked for me when I first bought the phone.
I unlocked the bootloader - unofficial version, installed twrp, tried to flash a rom, bricked my deice, than I managed to flash 7.2.3 global stable official rom - my bootloader was relocked, but sim1 could no more connect on 4g network.
while searching for it manually I can see it, but when i click it to connect, it just registers on 3g network.
since than I have tried to reset the device, full erase, no luck.
I installed global developer rom - with locked bootloader - no luck
I received a code to unlock bootloader, i Unlocked it, but still no 4g connection on sim1.
Any idea what could be wrong?
P.S.
If I put the same SIM in slot 2, 4g connects with no issues, but I want to use that slot for the Microsd card.
And I kind of found the culprit.
The phone that is sold in many countries comes with customized miui 7.1.9.0.0 (note the extra 0) and on this rom version 4g works on sim 1, on global versions it does not.
And now I am searching for a customized rom that can't be found anywhere.
Well I had the same version 7.1.9.0.0 (the unofficial multilanguage) when I got the phone, but I have not activated the 4G on my providers. In the mean time this rom had many issues (didn't recognise the second sim etc) so I flashed with EDL and MiFlash the original Global rom (7.1.7.0) and was ΟΤΑ updated to 7.1.8.0 . Since then I have no 4g on SIM1 but it works fine in slot2
I then got permission to unlock bootloader and unlocked it by flashing the official Chinese Dev 6.3.31.
Someone on the official site reported that the baseband of the AOSP and/or 7.1.7.0 solves the problem if you flash it manually via fastboot... I tried all the following basebands but no luck either.
- AOSP rom baseband (A.2.0.c1.1-00005-8976_GEN-PACK-1)
- Stable 7.1.7.0 rom baseband (A.2.0.c1.1-00019-8976_GEN-PACK-1)
- Stable 7.2.2.0 / 7.2.3.0 rom baseband (1-00019-8976_GEN_PAC K-1.49420.2 .)
Now I have the Greek Stable 7.2.2.0 (based in the Chinese Stable and made by the official fan site in Greece Xiaomi-Hellas) and yet no 4G.
It has been reported as a bug on the official site and as they say the developers are looking to solve it within the next updates..
Hi Project_P we meet again! heh
OP: if you don't need dual sim, try adding a dummy sim on slot 1 and turn it off and keep your normal sim in slot 2. That fixed the issue for me (obviously not ideal if you need dual sim OR if you need to expand storage).

That is the trick, I want to be able to use the microsd slot also. I am thinking of stripping a sim card and glue it to a microsd card as per the many tutorials out there.
Have you tried changing the cellular network type to "LTE" or similar?
I managed to regain 4g by doing this

I have tried to select it manually, but as soon as i click it, it just connects to 3g network.
There are many people who have this issue on en.miui.com/ thread-265011-1-1.html (correct the link) including me.
I came from a modified ROM 7.1.99.99 by the seller and I flash Miui (7.1.8.0) without unlocking the boatloader. Result: No LTE.
I flash the 6.3.31 the same way. No LTE too.
I set preferred network type to LTE only and no signal.
I've 4g on SIM2 when I've two SIM cards and sometimes on SIM 1. It's not stable
Hello,
I am French and I also got my phone with the Rom 7.1.9.0.(0) and I also lost 4G on slot 1. Sometimes I can have it on slot 2 by putting a second SIM card slot 2, but it is very unstable and sometimes I lose it also on slot 2. I installed all the Rom that exists but the Chinese / English, but nothing has changed . Even forcing the preferred 4G, I stay in H / H +. It's hopeless, now I think selling it but I will lose money because the 4G does not work.
Up ! We need some help here

Same problems here. Have to try changing to SIM2 slot and will report back. Weird bug.
edit: Better late than never. SIM2 only supports Nano from what I can tell. Couldn't switch since I'm on Micro. Will have to try with another SIM.
Same issue here. I lost 4g in sim slot 1 somewhere along the way through changing MIUI roms (Official/Dev/China etc) trying to unlock officially.
Until today with SIM1 slot Active, and SD Card inserted - No 4g anywhere.
Today I tried the hardware mod (sticking SIM to SD Card) - I now have 4G!

This is a method to get 4g working on SIM1 for a while. I got this info from XIaomi forums:
1. Turn off your phone
2. Put two simcard (micro & nano) that support 4G
3. Set data/internet to simcard 2
4. Eject your simcard tray without power off
5. Remove simcard 1 and put only simcard 2
6. Set LTE only on simcard 1 (using *#*#4636#*#* method)(dial that number, click phone information 1 and "Set preferred network type:" to LTE only)
7. Eject your simcard tray, and put simcard 1 again
8. Wait a few minute, if simcard 2 change to H+/3G
9. Switch data/internet to simcard 1
10. And ...... 4G/LTE work again using simcard 1.
11. After this you can eject the tray again without turning the phone off and swap SIM2 with microsd card.
I have the exact same situation as OP, even living in the same country. The thing is other users on the phone's softpedia section don't have this issue after flashing the 7.2.5.
I was hoping the 7.3.2. OTA would resolve this but there's no change.
My bug report was closed saying an update will come: http://en.miui.com/thread-280981-1-1.html.
Edit: I don't have a 2nd SIM to try that, nano-SIM too.

Whenever you can do the truck, do it. I also got the update to 7.3.2.0, but it is now back on 3g. I will do the mod again now.
A few have reported that a factory reset solved some issues.

I have the same issue with my handset too. even after update to 7.3.
Today I tested with only nano sim in slot 2 & it started finding 4G signals.
But slot 1 still work only for 2G & 3G
Hello,
I will repeat myself once, but I can confirm that if you received your phone with the Rom 7.1.9.0.0 dealer, it is because of her that we lost 4G on slot 1.
I really tried everything, even change the line build.prop but nothing has changed, still no 4G on slot 1.
Maybe if Xiaomi is an update of the Baseband, we can recover but this is not certain.

I know that, but still, it should work normal with international rom, because it uses the same modem as all redmi note 3 snapdragons out there.
Basically, Redmi Note 3 comes in 3 versions, two Chinese ones (One with MTK and one with SD650) and Global one(SD650). The Global version is the one that is sold in India, Taiwan, Singapore and part of Europe. The Chinese SD650 version, mostly sold in China, says it supports more bands than the Global one.
Chinese SD650 version LTE bands:
B1/B2/B3/B4/B5/B7/B8
B38/B39/B40/B41(2555-2655MHz)
Global Sd650 version LTE bands:
B1/B3/B5/B7/B8
B38/B39/B40/B41(2555-2655MHz）
I bought the Chinese one as I need to have Band 4 to work with my USA carrier. It worked when i was in China, but same unfortunate thing happens the me when I came back to the States and wiped my phone to dev. I can't access 4g band 4 on Sim 1, 3g connection is bad on Sim1 too. Sim 2 works fine for two days and then the 4g downgrades to 3g and then 3g connection is on and off.
Hello everyone!!
I received my Redmi Note 3 Pro last week. Yesterday, I received Xiaomi message saying I had been allowed to unlock bootloader. I did it, I flashed TWEP and SuperSU.
I was trying to unlock the 800mhz LTE band, although I had LTE with the other banbds, with the tools QPST and QXDM. First of all, I did a backup with QPST, in software download. In QXDM, I edited 06828 line, following this tutorial (http://forum.xda-developers.com/redmi-note/general/unlock-lte-bands-step-step-xiaomi-mi-t3084774), and transforming my original number to make it has LTE 20 band, with an app of Play Store.
What I got is no LTE, when I put the original code, after reboot, it kept without LTE. I flashed miui.eu ROM, later Resurrection Remix and today, fastboot ROM V7.3.2 official with MiFlash, and there is no LTE anymore, except in RR, in which changing the mode from settings, it catched LTE (but no WiFi).
Therefore, I think I need the originao baseband to flash it trhough TWRP or whatever, to make the phone has LTE as it had.
Thanks!!
Regards!!

With 2 SIMS, no LTE on any of them. With SIM2 LTE. With SIM1 no LTE.
I also tried this: http://forum.xda-developers.com/showpost.php?p=66889532&postcount=13 But not results at all. After putting another time SIM1, SIM2 gets LTE, but SIM1 doesn´t.

Dont give up miguel! Are you sure your carrier has active band 20 in your area? I've unlocked extra bands and what I've found is with our note 3SD's we cant check the frequency that our phones are actually using to determine what band we have in our environments. The reading of the incoming frequency(number) isn't built into the software. There is that small disconnect between our roms and the hardware. Unlocking extra LTE bands work. I unlocked all possible extra LTE bands. The problem is I cant tell what bands the carrier I use is using by looking at my phone to see what band its connected on.
The best way to see if band 20 is working is use another phone that doesn't have the hardware to software disconnect. See if the device connected to lte band 20 and if you have connectivity. Then on the note 3 only enable band 20 LTE on line 6828 of sim0. I'm not sure what the value is for only band 20 LTE. Maybe someone can post it.
After you restart the phone, switch the sim to slot 2, go to cellular networks in settings and connect manually to your 4g network. After it connects and before it gets data, pop sim out while phone is on and put the card in sim0 slot. let it load for a few min, and if you don't see anything after like 3 min go to cellular networks and see if you can select the local 4g network that you know works and on band 20. If it cant see the network or doesn't automatically connect then band 20 wont make it past the phone bandpass filter.
A bandpass filter is the only thing that stands between us and being able to receive all frequency of signal: https://www.google.com/search?q=bandpass+filter&ie=utf-8&oe=utf-8
If the filter is infact the reason our unlocking full bands doesn't work then I need someone to link a bandpass filter from ebay that will allow the extra lte bands and write a short tutorial on how to solder in the new filter.
I think unlocking bands the way the hardware currently is already works. I'm not in a location to be able to test my successful lte bands unlock until next month when I'll be on AT&T.
Good luck and please PM me any new information on nv memory hacking on redmi note 3's. I am very interested.
Any progress? I can't test Band 20 because my provider doesn't support it.

Hello everyone!!
I received my Redmi Note 3 Pro last week. Yesterday, I received Xiaomi message saying I had been allowed to unlock bootloader. I did it, I flashed TWEP and SuperSU.
I was trying to unlock the 800mhz LTE band, although I had LTE with the other banbds, with the tools QPST and QXDM. First of all, I did a backup with QPST, in software download. In QXDM, I edited 06828 line, following this tutorial (http://forum.xda-developers.com/redmi-note/general/unlock-lte-bands-step-step-xiaomi-mi-t3084774), and transforming my original number to make it has LTE 20 band, with an app of Play Store.
What I got is no LTE, when I put the original code, after reboot, it kept without LTE. I flashed miui.eu ROM, later Resurrection Remix and today, fastboot ROM V7.3.2 official with MiFlash, and there is no LTE anymore, except in RR, in which changing the mode from settings, it catched LTE (but no WiFi).
Therefore, I think I need the originao baseband to flash it trhough TWRP or whatever, to make the phone has LTE as it had.
Thanks!!
Regards!!

check link in first topic above, there is manual how to unlock B20 band and in step 2 use that commands instead dialers code (you see nothing on phone, just your phone opens port in device manager in PC). I have tried unlock B20 but without success and now I dont have any LTE
I am on AOSP 5.1.1

when the phone is booted up go to developer options, turn on usb debugging. Go to notification bar, turn off MTP mode. The phone should say, connected as installer. Then you go to your adb folder and open a command prompt and put in the three commands, one at a time.

i tried what you have posted, but still nothing happens, no ports tab on the device manager
i found the error, i typed usbconfig instead of usb.config
done editing,, is there an app where i can see if the bands are added??
or just by enabling the data to check for lte?
although i think it worked.. before no reception on some part of our house
now i got signal on those areas.
i researched all the lte band provided by the network(both sims)
i come from
11110000000000000000000000000000011011111
to
11111010000000001000100000000000011011111

Dont give up miguel! Are you sure your carrier has active band 20 in your area? I've unlocked extra bands and what I've found is with our note 3SD's we cant check the frequency that our phones are actually using to determine what band we have in our environments. The reading of the incoming frequency(number) isn't built into the software. There is that small disconnect between our roms and the hardware. Unlocking extra LTE bands work. I unlocked all possible extra LTE bands. The problem is I cant tell what bands the carrier I use is using by looking at my phone to see what band its connected on.
The best way to see if band 20 is working is use another phone that doesn't have the hardware to software disconnect. See if the device connected to lte band 20 and if you have connectivity. Then on the note 3 only enable band 20 LTE on line 6828 of sim0. I'm not sure what the value is for only band 20 LTE. Maybe someone can post it.
After you restart the phone, switch the sim to slot 2, go to cellular networks in settings and connect manually to your 4g network. After it connects and before it gets data, pop sim out while phone is on and put the card in sim0 slot. let it load for a few min, and if you don't see anything after like 3 min go to cellular networks and see if you can select the local 4g network that you know works and on band 20. If it cant see the network or doesn't automatically connect then band 20 wont make it past the phone bandpass filter.

Sorry for late reply friend. I first tried to just enable the LTE 20 band, disbaling the rest, but no result, I would try that hardware hack, but I will have to change to MIUI 7 once a time more.
I will give u more news soon!!!

Try CM13 build from @banmeifyouwant
I have fully working LTE/4G now 100% of time in Vodafone, UK. Before on MIUI... Only in some parts of Manchester, about 10%, now, perfect

finally LTE has worked with this CM13 but B20 is still locked
So by a stupid mistake I have selected in *#*#4636#*#* the Radio Band to USA. The signal suddenly dropped and it stopped working at all, the nework does not connect except in 4G and only for data. Calls and text are not working, only 4G data works fine. This is on the sim1 though. On sim2 all is ok (except that with the X829 ROM, on sim2 I have no data, and on sim1 I have no calls )) ). I was on sim1 when I've changed the Radio Band, so I guess that only this one got affected since sim2 is working properly.
Is there any Radio Band files that I can restore? Or some app that can restore the settings of the modem?
Any help is highly appreciated.
PS: Reinstalling the ROM (clean or dirty) doesn't help. Factory resetting also doesn't help. I would downgrade to 014s but I'm afraid not to end up with a brick.
Change the rom

If i were you. I would change the rom from china to indian rom. It would help you. The radio band of chinese rom and the indian rom is different. It would replace the radio band of chinese rom and if it doesn't work. Then return to the chinese rom
I'm 100% sure it would help you.

I did the same thing by my mistake.And my le max 2 also became not able to connect internet. In my case, it can't connect both 4G and 3G .
But I fixed it. But I don't know that it get back to the original completely.
I'm japanese.And I'm sorry for that my English skil is very poor.
My current rom is Le2_X820-MAX_ROW-5.8.015S_V29_CUOCO92.
I used DFS CDMA TOOL and checked the items on the "Band Preferred" same as "RF BC Config".
1. download HTC Diag Driver. You have to customize .inf file later.
2. conect device to your windows pc and choose MTP and USB Debugging.
3. enter the follows command.
"adb shell"
"su"
"setprop sys.usb.config diag,adb"
When you enter this command, your device change over diag mode.
4. diag driver install.
You have to find hardwawer ID from device manager.
And replace the hardware ID in .inf file.
5. If you install diag driver correctly, you will be able to use DFS CDMA TOOL.
sorry, I can't explain any more..English is difficult...
I bought my phone from china and I'm in US, and it works perfect on stock with LTE enabled for AT&T by default. Might I ask why did you change it to US band and it stopped working? It would still work right?

Many thanks for the advice but it didn't help. I had installed the indian rom and then to the chinese without any change in the behavior of the modem. I'll try the chatmonchy's advice to see if there will be any improvement.

Actually I'm in Europe and looks like we use slightly different bands (??). I get 4G data but without calls. To other networks like 2G and 3G it connects sometimes but it's for few seconds only. I even don't remember what made me change the bands to USA, I guess I was curios what settings those were. The options are "USA band" and "Band 6", neither one is working well for my device. And strangely though, there is no other option to go back like "Auto" or something. It seems that I'm not the only one that did it. After a google search, it turned out that a lot of people had the same issue. For some, the factory reset helped, for others was flashing via TWRP the radio bands again.
I had solved the issue and I will post a guide later on for those who want to unlock additional bands or did the same mistake as I did.
Thanks for the help guys.

thread: [SOLVED] Accidentally changed the Radio Band to USA
Hi, gyus
I had the same problem, i select USA band and everything went wrong,
The simplest way for me was:
installing "X820 LeMax2 RevolutioN_Team Resurrection Remix", no other from TeamSpain, only Resurrection Remix
http://revolutionlemax2.blogspot.al/
https://mega.nz/#!T9o0wAhJ!iLa9mrPAr...VkCg3_L-q2RgnA
then after installation, go in dialer and call *#*#4636#*#*.
There are three band: Automaic, USA, and EURO.
I select the EURO and everything i'ts OK.
BEFORE DO ACTIONS DON'T FORGET TO BACKUP ALL THE ROM WHERE YOU ARE WITH TWRP

Does not help. If I go to servise menu (dial *#*#4636#*#*) , I see Radio turned OFF and I can´t change it. How to solve this ?
Did you post any guide how you solved the issue?
Unfortunately USA band selected
Hi,
I live in India. I bought Oppo F3 Plus (CPH1613) 4Gb Ram, 64GB Storage, Qualcomm MSM8976 Pro Snapdragon 653 a year ago and was working too much fine. I was wondering about Qualcomm mobile secret codes and found this *#*#4636#*#* . I dialed this and accidentally changed radio band to USA band and suddnly on instant my mobile didn't get any network signal. From then, I went for Oppo care, and mobile repairing shops and self tried and tested for lots of time; but everyone unable to bring phone to normal. I reset my mobile, flashed stock rom for countless times, wiped all data but nothing helped me out. Finally i rooted my oppo f3 plus and tried to boot in fastboot mode; but Oppo removed bootloader and fastboot mode from 2016 (as posted in XDA). I got a little link about resetting USA band to automate and is erasing modemst1 and modemst2. But again it have to be performed from fastboot.
Help me out for my mobile.
You can flash a modem file, it will reset it as well. Changing the ROM won't update the modem configuration. Try to search modem files and flash them via TWRP.
Hi, I downloaded and installed Lineage ROM, everything was working fine but I found that I was not able to send text messages (receiving messages was okay), I tried change values under test menu (*#*#4636#*#*) but problem persist.
I tried clean installation of new ROM (Aosp).
I tried install new firmware from:
https://forum.xda-developers.com/re.../firmware-xiaomi-redmi-note-5-5-plus-t3759683
And baseband from :
https://androidfilehost.com/?fid=746163614322262750
And finally, text messages are OK, unfortunately I am not able connect to 4G/ LTE networks now. Only 2G and 3G networks are working. LTE services were working without problem on original Miui and Lineage ROM.
Can someone try help me how solve it ? I would really appreciate any ideas.
Do you think this can help?
https://androidfilebox.com/app/redmi-5-plus-modem-firmware/
Thanks in advance and happy weekend
i have the same question! +1
I tried fresh install original MIUI ROM, but it did not help
http://en.miui.com/getrom-340.html?m=yes&mobile=2 .
LTE is not available still.
I did not try this method still: https://androidfilebox.com/app/redmi-5-plus-modem-firmware/
But I don't have another option I guess.
With LTE no Problems = https://forum.xda-developers.com/redmi-note-5/development/rom-omnirom-t3823189
Unfortunately LTE is not working on this ROM (Omni) for me too, but I expected it, because as I wrote I tried original MIUI as well. It's problem of wrong firmware, baseband, modem or something, because hard reset or flashing new rom don't fix it. Btw, this morning I was in big city in my country and my phone was able connect to LTE, but it was 1800 or 2100 MHz, which are available only in bigger cities. When I came back to home, it showing only H+ again. It seems my phone is not able to connect only to LTE on 800 MHz (B20) currently, which is most widespread LTE frequency in my country and this one is only available one in my location. And I was able connect to this network before. Unfortunately I don't know how I can bring it back.
Solved.
My friend share her .xqcn file with me (she has same phone) so I flashed modem file via QPST Flash Tool to my device. Xiaomi started receiving LTE in my location- B20 frequency band, unfortunatelly it was continuously connecting and disconnecting between "no signal" and 4G.
The next step was flash MIUI 10 Global Beta ROM 8.8.9 to my phone via Miflash. LTE seems be stable and fully working now.

i ran into trouble with this. the firmware you have and lineage your using is now outdated but i tried with both your version and the updated ones and 18.x version of lineage does seem to detect my sim card and the new one lineage 19 detects it but i get the error from verizon that my phone cant be authenticated for calls but everything else works. i notice when im running updated stock, the sim card reads fine and service works normally but before when i had it running older stock firmware (android 10) i got the same thing. everything would work but calls. then when i updated the stock firmware, everything worked. so im not sure what im missing here when trying to follow your direction for getting this installed but maybe you know whats going on since your a verizon user using the global variant. please write me back when you get this. thanks a bunch

Well I only had the phone as a test for getting mmWave 5G on the global variant, which isn't possible due to a proprietary solder pattern on the board, but I no longer use this phone.
What I would recommend for you is to flash the NON-HLOS.bin from the stock firmware that worked for you without a problem. It's the modem firmware and it could cause problems like that. I didn't have any issue with my sim card, calls worked fine over CDMA and I could get text messages and LTE data worked.
I have never even seen the error that says the phone can't be authenticated for calls. Is it coming from a verizon app or is it an android error? I would also suggest to make sure the correct APN is being used, should be VZWINTERNET. I had an issue with an older motorola where it would for some reason randomly switch to some other VZW APN that was wrong.
I didn't do thorough testing of this, I just wanted to get the baseline for getting custom roms running, but I didn't encounter anything like what you're going through. Considering you had this problem on a certain stock firmware version, my best guess is the modem firmware. I did flash the VZW firmware on the phone and that worked as well, maybe you should try flashing that modem firmware? I didn't have issues, but I can't 100% recommend it because VZW expects the QTM 5G modules to be present, which it isn't. I don't know if this could cause hardware issues. Other than that, the phones are 100% identical.
Sorry I didn't get back to you sooner, XDA's "stay logged in" checkbox does not seem to work correctly and this website is a hassle to navigate.

I'll try flashing the Verizon modem when I can. Recently, my service randomly died and I turned on airplane mode to restore service but the unable to authenticate for calls happened again when it worked fine before. I had to restart the phone to get calls working again. No idea what it was about. As for the apn, I was going to transfer the apn over from my s21 plus but it seems the verizon sim already sets the apn automatically to where it's not able to be changed. It's all greyed out. I noticed that I also got the unable to authenticate for calls before I updated the firmware. I bought the phone used and it was behind in updates. When I updated to the second most recent update, I noticed calls started to work. I haven't updated to latest since installing magisk with root broke the Ota update. I could update with a pc easy but I haven't since the things listed here are now out of date so trying to stay with the firmwares listed here. Lastly for 5G, i checked the bands the phone supports before buying it and I believe it matched one or two bands with 5G and I do get 5G in few areas. It also supports most LTE bands that Verizon gives. I didn't see any cdma support, only GSM but from my understanding GSM and CDMA is an older thing when it came to 2g or 3g. What I've gathered is if voice can be done through LTE then calls would work. So just a tip on the testing and things I've come across so far
I just noticed in the thread that voice over LTE doesnt work. I wonder if that's my issue? However I see CDMA voice is working so says the thread here. It's confusing at this point

Ok I remember now when I was trying to enable VoLTE the calls just wouldn't work. I didn't get an error though. You have to turn off VoLTE for it to work again. This is in Settings/Network & Internet/Mobile Network/Advanced Calling.
The developer of the lineageos gsi was aware of this issue and tried to fix it but I guess it only applies to whatever phone he was testing with.
As long as the APN says VZWINTERNET you should be fine. Trying to flash over another APN isn't worth the effort and can cause more problems than it could fix, the values are correct as long as the right APN is being selected.
CDMA is Verizons standard calling radio technology, was also used by Sprint. CDMA is being phased out though to be replaced by LTE entirely. I don't know when this will happen. If you check the GSMArena link in the first post you will see all the bands listed on this phone, and it does support CDMA, which is why calling works without VoLTE.
Considering you were having problems on the stock firmware, it seems like your issue is more than just VoLTE not working, because what you explained is not a typical issue, and no matter what stock firmware you were on, VoLTE and CDMA calling both should've worked out of the box. I would test to make sure your Verizon account even has VoLTE support first because that seems to be the only reason for error messages popping up like you had. Although this doesn't really matter though because this method does not support VoLTE from what I tested.

Well I will do more testing here shortly. I noticed that on lineage 18.x (Android 11) I get a missing Sim card error when a Sim card is present. Then with latest lineage 19, I get no sim error except the calling authentication error. I have Verizon firmware with the modem now so I'll try testing lineage again with the Verizon modem to see how it plays out.
UPDATE: i tried both lineage 18.x and 19 that have android 11 and 12 in them. still have the same result of phone not able to be authenticated even after flashing verizon modem. ive even tried other gsi roms and ether ended in a bootloop or an error saying petition was too small. it seems that the apn for verizon becomes greyed out and changes the apn settings itself from the sim card. ive even tried using the latest stock update with the gsi and same results. (had to pay a site for the firmware since the newest update is exclusive?) at this point, ive decided using a gsi on this phone with verizon service a bust. so ive decided to stick with stock with root and magisk.
on a side note, i noticed the newer updates have provisioning apps installed on the stock firmware for carriers. not sure if that makes much of a difference but im done messing with it.
First of all thanks Knuxyl for your guide, it helped me to install a GSI ROM n my Edge+, I found really good images but in the end all the images I tried had the same issue... "bluetooth devices connects but transfer no audio", I dont think this is a ROM issue, because I tested 6 android 10 custom ROMS and 3 android 11 with the same result, so I wonder if you dont have this same issue or you manage to solve it.
Im using crdroid v313+211013 and BT wont connect to anything unless I disable A2DP hardware offload inside developer options, with this option enable, the phone pairs with devices but transfer no sound also most of audio codecs are not selctable, they are disabled (grau color), if I enable gabeldorsche stack, the phone is unable to pair with devices. Please if anyone have this issue or suggestion let me know. Have a great day.
@Knuxyl - Thanks for putting this guide together.
@ifritknight - Indeed, I also couldn't get bluetooth to work. I got bootloop with Havoc and LOS 19. LOS 18 worked well.
hi , thank you , there are upgrade?
Well this platform isn't widely supported. I wrote the guide just to get us a foot in the door. The problems with VoLTE, sim, and Bluetooth are more than likely an improper implementation of the new oem partition stuff Google started enforcing, which started with Project Treble.
I did request the source for the kernel for global retail and verizon variants like a year ago. They finally released them within the past month on their github, so maybe a lineage developer could take a peek and possibly officially support this phone. This phone is too good to not support, but the display over usb c would take some effort.
