Phone Radio NOT working/turned on with converted Axon A2017 to Axon A2017U

Hello, first of all I want to let you know that I am not an expert but have so far been able to convert my Axon A2017 to the US A2017U version.
Big thanks [email protected] for supplying the necessary files.
I have:
-unlocked the bootloader
-rooted the phone
-flashed successfully B20
However, When I upgraded to B29, I lost TWRP and the cell radio of the phone is non-responsive. It won't even turn on. Bootloader is sill unlocked. I made phone calls on my T-mobile network when it was the origional A2017 B8 version. So I believe the bandwidths are compatible.
I have already done the following troubleshooting: (note: WIFI currently works just fine)
-My network is with T-Mobile, and I have been using a different axon A2017U for over a year with no problems.
-When I type *#*#4636#*#* and got to phone Info says, GSM Service: Radio Off, and the Turn on Radio button does nothing.
- I have tried working with every setting in this menu with no luck.
-When I insert my SIM card that is working on my current axon 7 into the converted A2017U, it is able to pick up T-Mobile network u.s. LTE, (fast.tmobile.com) and T-Mobile US (tmus). However, there are no bars because the radio is not turned on.
-When I try to search for new networks an error message saying, "network search cannot proceed when the data service is enabled disabled it?" So I disable it and nothing happens except for an error message saying "error while searching for Networks".
-In network mode I have switched to every option available, LTE/wcdma/GSM, wcdma/GSM, and GSM only with no result.
I am currently running Android version 6.0.1 on build B-29. Any help to get the radio up and running to receive phone calls would be greatly appreciated. Everything else is working except for the phone radio to send and receive phone calls.
Thanks for any Help.

Do you still have your IMEI or did the partition get corrupted?

I check the number with several online checks, as well as T-Mobile, and they are unable to bring up any information about the number. I imagine it got blocked or corrupted during the upgrades.
What do I do to unblock it or make it functional again?

Go to settings>About>Status and check your IMEI number. If it's blank its noyt gonna work on any network...
You might be able to restore it if you have a backup of it - no-one will give you their backup as you then have their phone - or as a last resort, you might need to restore to the stock Chinese Rom again and see if that fixes it...
Good luck, I'm off to bed after a long backshift...

Thankfully the numbers are there on both IMEI slot 1 and IMEI Slot 2. Thanks for your help. I hope to hear from you after a good night of rest.

Flash the correct modem/bootstack for your device.

Just go to the LineageOS thread and download the A2017 modem file, then just flash it

Sounds Good
Will I need TWRP to flash it or can is just use the Reg. recovery system?

You need TWRP. Just install it with axon7tool via edl if you don't have fastboot, or try axon7toolkit

Here's the latest update:
I loaded TWRP onto the phone and installed the file A2017U_N_Modem.zip. (Several Times)
nothing has changed. The radio is still turned off and no signal is being picked up from my carrier T-Mobile.
While loading it says: Loading A2017U_N_Modem for nougat system. I am not running nougat and I cannot find any other modem to download. Will that make a difference?
Any other suggestions are welcome?

You need to flash the A2017 modem, not the A2017U one

Okay it works! I've got signal but when I try to make a phone call and my other phone picks up I can't hear or say anything. Any idea what's happening? I have tried refreshing the signal with no luck.

Hey man, I'm having the same problem with my Axon 7, brand new A2017U. Turned it on for the first time and I haven't had an ounce of radio on. Same things you've tried I've tried and it refuses to work. Mine is not rooted and I don't want to. I've tried downgrading my update and to no avail. Factory reset etc. I've contacted ZTE and they said they have forwarded my details and my phone details, storage size, color etc. To the necessary representatives. I think I'm gonna be sent a replacement, but just wanted to let you know your not alone.

Unlocked LG G6 US997 Activation Issue on Verizon with Lineage OS

I just got an LG G6 US997, unlocked the bootloader, flashed TWRP, and installed Lineage successfully. When I went through setup, the wizard never got past the SIM activation screen so I had to skip that. The service state shows as "Out of Service" with a signal strength of 0. I can't send or receive text messages or receive calls, but data seems to work just fine. I've found that if I place an outbound call, everything seems to reset and then the service state moves to "In Service" and I get a signal strength. After that, I'm able to send and receive texts and receive calls. Tried a new SIM from Verizon... no change. I tried flashing the latest stock ROM (17A) to see if there was still a problem and everything activated without any issues. I was able to send and receive texts and receive calls no without issue. After trying another clean install of Lineage, I'm back to the same issue. Any thoughts?

Same for me
Thank you for posting, I was able to get my text messaging working after making a call. I used TWRP to flash Lineage 15.1 and MindTheGapps.
Any updates on the long-term usability of this ROM?
Cheers

You can try to not use a sim to set it up then use the method that scy gave

a2017u b20 firmare on a2017g modem problem

Hello
Could someone help me?
a2017u b20 stock. Flashed via EDL
I have a2017g version. but i need wifi calling working(and it works perfect on b20).
But i have some strange issues with modems.
I tried a lot.
ZTE_A2017X_Oreo_V2.10B12_Gmodem
ZTE_A2017X_Oreo Gmodem for 02 version
ZTE_A2017X_Oreo Gmodem for 03 version
They worked, and wifi callong was working too, but - funny bug - when someone calls me from iphone X(exect iphone X) then i cant hear him. and after i call back all is normal. But cant receive calls from them.
The only modem, on which there is no this bug is ZTE_A2017G_MODDED_MODEM_FOR_OREO_A2017V3.0.0B01-2_TURKDEVS
from this thread:
"https://forum.xda-developers.com/axon-7/development/anroid-8-official-mifavaor-ui-5-2-beta-t3707605"
But with this modem i have only 000000 instead of both IMEI, and after 1-2 there becomes no service on the sim 1(sim2 works but wifi calling works only on sim1) and after reflashing this modem it is good for 1-2 days.
I almost want to brake this phone because of such stupid bug.
Anyone use a2017u b20 firmware on a2017g? which modem do you use and do you have such problem.

hello, as i wrote before i tested b03 and b02 modems, flashed in twrp. On both there is a roblem with incoming calls from Iphone X.

Hello everyone.
Also tested on b12 by nfound. The same issue there on b12 g modem. I cant hear iphone X owners when receive calls from them. Hear them well when call them back. On Turkdevs modem incoming calls are ok, but no imei and "no service" after 1-2 days. I think i already tested all current roms. Maybe someone could mod b03 modem as turkdevs b01-02 from 1st post?

I got the same problem since yesterday. My device was away for a battery replacement some days ago. After I get it back everything was fine. Yesterday the modem stopped working. In my option I changed nothing. I just get no signal anymore. I'm still on 14.1 Nougat. I have tryed to flash the modem again, made a system, EFS, bootloader and twrp recovery but nothing worked so far. I also tryped to reset network settings and tryed another sim card..

Not yet. I was hoping that there is a solution with less effort. Is this the only know solution?

I've actually never heard of this problem, so I'm not sure what the proper solution is. Going to stock via EDL has always fixed my problems in the past, so that's why I recommended it. You can give it a shot, it's not like your phone is very useful in it's current state as a "phone to call people with".

I already read something about it. Thanks for that advice again. It's the absolute wrong time for a error like this. I have absolute no time/no head for this.

My problem is totaly different.
Modem works. G modem (b12,b03,b02) works, but only one problem - incoming(outcoming good) call from iphone x is without sound - i cant hear them. But on one modem - b01-02 from turkdevs i can hear them, but there is no imei - 0000 instead of imei and after 1-2 days "no service"
I started this thread because i think that here could be a man, who could make some magic with b03 modem and make some changes, wich will allow me to hear iphone x users.
Your problem seems like it just wrong modem flashed. maybe some other to try and you will find some which will work.

Is there any user here, who could edit modem?

phone says there's LTE service, but disconnects when making a call and cannot receive/send texts

I installed the latest lineageOS 19 version, rooted my phone then ran into this problem where the phone says i have service, but when i place a call it wont fully make the call. Then my mobile data will X out and i get pop up error saying mobile service is unavailable. I then tried lineageOS 18.1 and arrowOS and same problem persists.
formating between installs obviously.
I have looked at every option on this phone and tried combinations and everything in the network/system/ everything and still not working.
The process was actually very simple since i have some programming experience. Other sources mention possible baseband issues? On the fastboot screen it shows a baseband version. all the information there appears normal. I only flashed the boot image one time to root and didn't mess with any other manual flashing processes. Just used twrp. I didn't quite understand twrp at first and therefore didn't get a backup using it... iused adb to make a backup which apparently didn't work so Im lost and hope someone could help me out here. please and thank you!

If i may add I can use mobile data just fine, i can browse the internet and such (with wifi off and data on only) so i really dont understand. Is this a normal issue to have when using custom roms? did I trip some security that blocked me now? any input???
I wonder, though, this moto g7 is an A/B partition thing. so if i understand correctly, flashing twrp would not work and thus why i did not do that. it makes sense. But should i try flashing it, booting into it then installing lineage? even if i did i feel like that would give me same issue considering the method i followed got me into lineageos, plus root checker said i was rooted.

What I can tell you is what I had to do in order to get LTE (voice calls) running on my G7 - I was forced to switch over to LTE because AT&T turned off 3G here in the US and 4G without LTE is not good enough for voice calls:
Get the latest stock firmware and install it using e.g. Lenovo's "Rescue And Smart Assistant". That will get Motorola's Android 10 on the phone.
After installation, go through setup and actually make a call (calling your mailbox is fine). Then check your ims status (*#*#4636#*#*, goto phone info, pull ims status) to see that ims is actually working.
Shutdown the phone and start installing LOS (use the partition copy script too to make sure that the partitions not touched by LOS installation are updated "on the other flash bank").
Go through LOS setup, select a valid APN for your setup, set "LTE only" or "LTE / WCDMA" for the network and make a call. You should be good to go.
Again this is what I had to do to get LTE working with AT&T USA. YMMW.

I know this is way late, and you probably already figured it out. I didn't share the no text problem. The Problem isn't just the "LTE" setting itself. There is one more option(some Roms show it, some don't) I believe its in the phone app settings? VOLTE must be checked. I have noticed Some Roms do have this option and some don't. when volte is checked, it'll keep your data/internet on during a call, some Roms that option won't show up or isn't available. I haven't used G7 in a while, but I do remember the problem and how to fix (on my phone anyway).
