I don't know what else to try as I flashed a modem file and it still shows no signal. Even on stock firmware it says no signal. I'm pretty sure it's the correct modem file because the IMEI shows up but still no service. I put the sim in my Redmi 1S and it works fine. Anything else I can try? I flashed both the chinese modem and the modem for my phone already. It is model number 2014817. I also dismantled the phone and the antenna cable is connected.
Same here, did you got any solve ?

I hope I am posting in the right section.
I have a Samsung Galaxy S4 (I9505) and it was crashing on the stock ROM so I flashed the Imperium LL Rom v11.0. The problem I am having is my phone reporting no network signal or "Out of service". But not always. After a reboot I usually have network signal. After locking and unlocking the phone I never have. The signal usually comes within a few minutes. When my phone is reporting "Out of service" I cannot make calls but I can still receive calls. And after the received call has terminated I can still not make calls. After a few minutes the network signal icon comes and I can make calls. Until I lock my phone because it gets lost everytime.
Some info:
1. I was on a rooted Stock 4.2.2 before I flashed the Imperium LL Rom.
2. The IMEI seems to have changed. I never took note of it before flashing, so it might have always been different but the IMEI reported by the phone is different from the IMEI on the sticker underneath the phone battery. I tried the Xposed IMEI changer but the problem still happens so this may be unrelated.
3. While searching I found it could be an invalid Modem driver. In the settings the Baseband version is I9505XXUBMEA so I tried flashing the driver for that version using ODIN. No change.
4. I tried via Recovery to flash Slim80 Kernel Cleaning Script v1.9 and then the Imperium Kernel v3.3 but no change.
I did a factory wipe before flashing the firmware.
Any help or suggestions please?
Thanks!
I have actually solved this. What I had tried before was flashing the modem with the same Baseband I had previously ie: I9505XXUBMEA thinking that there were specific versions which needed specific drivers. Upon reading more I found out that newer versions of the modem should be installed and that XX was a carrier code and the last 2 letters are how recent the driver is. So I tried the latest modem (XXUHOE2) I could find similar to the Imperium Build which is XXUHOJ2 and it seems to be working. My phone retains the network signal when put to sleep.
The fact the IMEI changed is weird and I don't know if it makes a difference. Maybe it was always like this..but it is strange that it is different to the one on the sticker. The format is correct because only the last 4 digits differ.
Anyway I hope this info helps someone with similar problems.
How can I mark the title for this as [Solved]? I can't find any way.
Evening,
I have a signal problem on my N9005
Signal is just about non existent, so far, i've tried the following:
Factory resey/wipe cache
Flash modem with 2 different one, works good for 5 mins, then goes off again
Flashed about 5 different stock roms, same result, works fine for 5 mins, then stops
Flash a custom rom, same result lol
I'm now believeing it to be a hardware issue, unless someone has any ideas?
Change sim card would be step one .
Does this happen with all sim cards? Phone shows the correct IMEI? Was the phone ever dropped? Phone support's your carrier's radio frequencies? It worked properly with this carrier on a prior occasion ?
my phone is china model and after recover back to stock rom s288 row everything is going well but sim cards signal is not activated although the Imei is found ..
what can I do to get back the signal ???
If you have flashed CN version with ROW room you need to replace NON-HLOS file and flash it again. You can find NON-HLOS file in google. I think. If not I can send you the on that I've found.

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.
Firs

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..

Have you tried to reset to stock via EDL?

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?
Hi all,
My SM-G935F is not rooted and it has been bought network unlocked.
Yesterday I was browsing normally in 4G, the device became very slow and suddenly a message popped up "please insert SIM card". I have done the normal procedures of restarting and wiping cache partition which did not solve the problem.
In the meantime, I have tried the SIM on another device and it has worked properly.
I've noticed that the fields IMEI and IMEI DV are displayed as "Unknown".
I have searched for solutions but, because my phone is not rooted I'm not sure whether it applies to my case. Please note that I've made no change that could cause this issue, it has simply happened.
What could be causing this?
Try to reinstall the stock via odin. Maybe that will solve your problem. If not, it may be a hardware problem.

Thanks. I have installed latest firmware via ODIN successfully. However it did not solve the problem.
Baseband is also displayed as unknown.
If it is an hardware issue,is it repairable?

99% of the time, its a mobo replacement for this issue if it ends up being hardware related, and if a mobo replacement doesnt fix your issue, not much else will. Might as well strap it to a missile if a mobo swap doesnt fix it
SOLVED
Right, the problem has been solved for now.
I have taken multiple steps which have got me confused TBH, but I will try to recall them in detail:
(please note that before these steps I have attempted to flash latest firmware G935FXXS7ETA4 at least 3 times without CSC home before rooting)
1. I have rooted with CF Auto Root hero2lte
2. I have copied EFS, radio and nv_data.bin to a safe location in my PC.
3. Used latest TWRP flash.
4. Flashed latest firmware G935FXXS7ETA4 with Home CSC and that did not work.
5. Flashed latest firmware G935FXXS7ETA4 CSC only and after restarting a message popped up informing that the single SIM mode had been switched to DUAL SIM mode, and network signal was back on.
6. I have installed the app "phone info" which now indicates baseband version and original IMEI. Happy days!
Notes:
On the phone info app I get the following information displayed
Device Type:
hero2lite
Product Name:
hero2ltexx
Is it possible to change this back to the original name?
UPDATE
UPDATE
- Sometimes it switches from 4G to 3G ("E" symbol). 4G comes back on if I restart on safe mode.
- It disconnects from the network randomly, then it comes back on.
- Everything else works perfectly fine.
This is clearly an intermittent issue, could it be the modem hardware failing?
