Problem with my signal after i flashed 8.1 (Oreo) - Moto G5 Plus Questions & Answers

Hi!
I have rooted my phone, and i have flashed Oreo RR and everything is working, BUT...when i have 4G (LTE) my signal drops down and suddenly i dont have a signal. Even if i dont have 4G on my signal drops.
But if a am on 2G network my signal is full and no drops whatsoever.
I have tried to go back and flash 7.1 But same problem there.
So my question, is it someting wrong with my phone? Because i remember that i didnt have these kind of issue before i flashed a ROM.

Okk,then I have no idea about your problem.
Sorry brother

Any one found a fix for this? I also have random signal drops even after some tweaking in the mobile data settings. This doesn't happen on stock or other nougat roms. I really want to run Oreo on my phone
EDIT: I still have 4g+ when my signal drops but for a few seconds people cant seem to reach me because of the signal drop

It's a bug in Oreo, there is no fix.

Ok, thank you for answering! Finally a clear answer. Guess people just live with it

You have to restore full nougat stock image.....and then if you wanna go oreo then before doing that you have to backup EFS partition....install then Only Pixel Experience pr Lineage custom roms....if needed after iflashing custom roms restore only efs partition from nougat into oreo...that should do the trick

yes bro 4G single drops Oreo rom...?

I have to say that after flashing any of the 8.1 roms it is a crap shoot whether I get any voice signal (4G) at all when I reboot. I kinda wish I never would have updated to any of these 8.1 roms. I know there was warnings when I first bought the phone about saving your EFS and other aspects of your stock rom and I did do that. But man,,I dont know if it was that the devs just didnt know or what,,,but I would have rather stayed on Nougat and not have to worry if my phone signal will come back after a reboot. And it happens with every 8.1 rom at some point and trust me those out there saying "well it never happened to me, give it time, it will LOL. Not complaining, we all signed up for this when we tinker with the phones like we do, but if I had known it would be like this then i would have stayed stock.

What if I used a stock debloated franco28 rom? Would that work the same way? Or do I really need to go back to full stock ?

Would a custom Oreo ROM still boot with a stock Nougat EFS partition?

Signal bars seems to be an issue with most Oreo ROMs I've tried (Lineage, PixelExperience, Ressurection, AOSPExtended, MSM). I've even tried flashing my backed up Persist/EFS. However I've noticed that my phone is still reachable and can make calls even when it shows the "No Service" message. As soon as it does the signal bars get updated so not sure if this is not just a UI glitch.

i believe it's an UI issue, i mean my signal bar drops every 3 minutes and changes from 4G to 3G all the time but the internet works very fast like stock

hello, friends. Specially those who are worried about the so many problems with signal moto g5 users face. Im here asking for help. i have a moto g5 (cedric) i was working almost fine with oreo stock. i say almost because some times when i lost signal it didnt recover like any other phone woud, i had to reboot. now from almost a week ago i had lost signal and now i only have 4g. no 3G and no 2G, so no voice calls going out nor incoming ones. i ve done hard resets, flashing stock 7.0 and going back to stock 8.1 and nothing. on saw 3g for a little moment coming back to oreo. i also flashed carbon rom wich is android 9.0 to see if a custom rom helped but it didnt. i only have internet now and sms. and this is very frustrating. ive checked persist folder and everything is correct there. i have my imei right, this phone is like new but not being able to call is like not having a phone at all. also why i have to reboot to recover missing signal? is just a pain. this moto phones are really problematic when it comes to Signal management.
things to consider too: im currently on stock oreo, just rooted to be able to check if persist folder was correct and to backup efs folder. also my operator uses 900mhz band as 2g and 3g wich is an european frecuency not common in latin america. maybe that has something to do with problems im facing. the rom has cedric_latam_cust as the baseband. can anyone help me find one frome europe? im wondering if flashing one from there could help. the weird thing is that it was working before with that baseband.
so many people losing 4g, i could be glad if that was my case and had 2g and 3g only with full internet and calling capabilities.
im sorry i know it is a little bit too much information. but i really need the help

Once you select automatic band with the rom I built you can flash whatever you want. The change remains permanent regardless of what rom are you going to flash afterwards (atleast for nexus 5x and nexus 6p)

Can confirm this works. You are a £450 life saver friend.
This needs to be stickied. There a lot of people with this issue. I've been telling people to use Chroma to get it working again. It looks like this ROM has more options tho.

Well I got stuck with this issue after traveling overseas. I already had a sim, but got no signal when I put it in upon arrival. Of course I pressed every button and changed every setting, who doesn't? Well it turns out the sim had expired and that was the original issue. It went downhill from there when I couldn't get any sim to work in my phone and had to revert to my backup OnePlus.
I've updated to the newest image, but I doubt there is any change that fixed this issue. Is there any way we can get this going without flashing another rom? I tried to get QPST going but didn't have any luck with driver setup.
The other question is how do you know it's fixed BEFORE traveling overseas again?
anybody success get band back to automatic after flash this rom?
pretty desperate as no technical service for 6p in my country,
flashed rom, multiple crashes, able to change radio to auto, still no signal. anyone?
This worked for me, 6p LTE signal drops. Before i Flashed rom, found the mm29m vendor image on afh, flashed rom, open gapps, vendor, rebooted. Had bunch of fc's but struggled to set everything up. Force stopped setup wizard. Logged into google.
Then did a factory reset. Earlier today on stock and on roms 4 lte drops, after flashing this, no more
Edit update:
Day 2 of no drops. Flashed 2 ROMs and all is well.
BEFORE I FOUND THIS FIX, I was losing LTE about every 3 hours, nothing fixed it. Flashed STK on toolkit, airplane mode, dialer codes, nothing.
Thanks OP!!
I am using a Moto X Pure XT1575. So sorry for my question not in the right place.
I have the same mistake to press USA band in *#*#4636#*#* and try many way to fix the problem. But, it is not completely work, I have 2G but lost 3G now.
I see that there is a thread in Moto X Pure about the Pure Nexus - Clark developing now:
forum.xda-developers.com/moto-x-style/development/rom-aosp-pure-nexus-clark-t3337479
@bitdomo: My questions is Can we modify this rom above Purenexus -Clark to make a Rom with Auto Band same as what you did for Nexus? If yes, please instruct/help to make this rom.
Thank you

Anyone facing signal problems on lollipop .87?

I was just using my phone as usual, and suddenly my 2 sims didn't work.. there's no sim all of sudden.. i tried on and off airplane mode but still no signal... i have to restart then only its back to normal.. how to fix this?
Because sometimes i need to make emergency calls and this just happens. Its bugging me.
Btw, no threads for general q&a? Hate to post a new thread for something minor bug like this..
I had same problem when I updated to .87..
could not find solution..
so reverted back to .60
which is most stable of the lot..
if your bootloader is unlocked & if you don't have screen freeze problem..
there are many good custom rom's..
try one of them..

check your imei *#06# and about phone info
there is a possibility you have null imei and baseband unknown., this is common known bug when upgrade to LL,
if it is confirmed that you got that bug, navigate through the troubleshooting area, there are many threads discussing about it though. thanx.

Lost LTE after flashing a ROM

I lost LTE after I flashed Ressurection Remix. I wiped after I flashed Ressurection due to the ROM constantly dropping service randomly. I had LTE perfectly fine with that ROM though. So afterwards, I tried Omni Rom and that's when I started only getting 3G and absolutely no LTE, no matter what ROM I flashed. I flashed the stock ROM, including flashing the stock modem and wiping modemst1 and t2, and still have no LTE, even on the stock ROM. Is there anything I can do? I'm fully rooted with TWRP, and have not had any errors upon flashing. I don't know what would have caused this.

I think you have to re-create the APN settings that your carrier requires for mobile data. It's possible that RR has APNs built in for various carriers and if that's the case, find the one for your carrier and make it the default. This is what I had to do when I flashed LineageOS and also after I re-flashed the stock ROM.

That's what I did, and even flashed back the original ROM and all I'm getting is H+ data now. Absolutely no LTE. Something had to have went wrong to cause the radio in the phone to stop picking up LTE.
UPDATE: I found out that it was the kernel that caused me to lose LTE. I flashed a different kernel and it brought back LTE.

Can you link what kernel worked for you. I'm having the same issues with LTE trying to use it on Verizon. I can get 4G to work if I change the radio to United States but then phone calls don't work. If I get it so that phone calls do work then the signal drops out all the time and 3g is only available.
Thanks.

Keep in mind, we can use G4 plus kernels and ROMs too, even if were on the regular G4.
ElementalX kernel may also work if that one doesn't work out for you.
Download according to your current ROM (nougat, marshmallow, etc), reboot to recovery, install zip that you downloaded, wipe cache, reboot, done. Turn off WiFi before rebooting to recovery, that way when you reboot after flashing the kernel it will go straight for mobile network instead of WiFi (;
Let me know if it works for you too!

Thanks for the reply!
I was excited, but it did not work for me. Still only getting 3G. Its weird because it constantly says I lost signal cause I went outside my home area. There should be perfect Verizon coverage here.
But when I set the radio band to United States( which I am in) the 4G works perfectly but then the network for calling/SMS is gone.
When the 4g works, the apns all change and then when I set the radio band back to automatic they change again but to something that has no 4G.
I also have no option to edit or add any APNs.

You know what's weird is I used to use Total Wireless which is on the Verizon network in my G4, and towards the end I was only getting 3G as well.
Which ROM are you currently on if you don't mind me asking?

Its not that personal of a question lol I don't mind at all. I am using Resurrection Remix. And the kernel that you mentioned. The sim came from my work phone which was a Galaxy S5 Verizon.
So does the G4 work on cmda AND gsm? I thought you had to get an unlocked version of one or the other?
I think the guy I bought the phone from said he was using it on TMobile.
He mentioned that the moto g4 had sim issues when it first came out but this one was a new one Motorola sent back to him.
Maybe this will help you out, I had LTE issues right out of the box on mine and fixed it with this:

I downloaded the rom and extracted the zip file. I'm not seeing where the NON-HLOS.bin and fsg.mbn files are?

Nevermind. Think I downloaded the wrong file.

VoLTE gone forever?

To address the issue, a lot of people (including me) lost their phone signals because of IMEI turning to "0" after flashing some 8.1 based ROMs.
There were few tutorials to get back the signals but now no matter what ROMs I flash, VoLTE isn't there at all.
Custom ROMs have the option but the switch does nothing, stock ROM doesn't have the option at all (see screenshot below)
I'm curious if anyone faced a similar problem and managed to get VoLTE to work.
I am also one of them. It was something in the early January build that made it happen. Because I switched back and forth on Stock and custom ROMS on December 2017 builds and everything worked fine.
I am just waiting for and OTA or Oreo update to see if anything happens.

For me, I have the same issue; but I guess my IMEI # is intact because when I dial *#06#, it returns me with 2 IMEI numbers for both my sim cards. what might be the issue in this case?
I'm curious about this issue with VoLTE. What's causing it? Is it reversible with a backup restore? Is it hardware specific or software specific? Do we have any workaround for it?
The 8.1 ROMs might have overwritten some files related to VoLTE
volte
any one knows how to fix volte?
Mod Edit: Removed rude/disrespectful quote
Don't call anyone stupid FFS. We don't have a solid proof what exactly is causing it. Atleast they didn't do it intentionally.

I believe Moto changed something in the latest 92/93 update that's causing permanent VoLTE loss to almost everyone flashing 8.1 ROMs.
I don't think so....i had 67.5....for me also volte is not working...
Only devs can tell the exact reason. what i think is if we knew earlier then when we try to revert to stock fro the first time when everything was working fine(VOLTE). we should've skipped that 2 lines (Erase one's) while flashing stock rom
What if i have EFS backup of Stock Rom ?
By flashing efs backup of solves Volte issue ?
Please let me know if anyone have idea about the same....

If you did the backup while your VoLTE was still working only then it could be of some help.

Well i had the efs backup when Volte was working and it did not work.
Not only is VoLTE broken but the network keeps refreshing itself.
Never thought flashing a custom ROM will make me get another phone but there's no other way.

Really sad to hear all this going on. Why isn't there any fix to it? Hope someone can resurrect VoLTE on our devices.
I'm on Oreo Pixel Experience and I'm scared to flash other roms. What should I do? Does any backup help?

As far as I've seen, No.
Restoring stock via fastboot or restoring efs backup via TWRP didn't do any good.

I hope someone comes up with a fix. I don't want VoLTE to be dead forever.

Thanks! I hope that too.
I'll be saving for a new phone and by the time watching if a fix appears.
someone please help us..as soon as possible
I managed to relock bootloader and fastboot stock. I skipped erase modem commands and 4g is working, however, Volte was not fixed by this.

I have this idea which I'm not sure will work or not:
A friend of mine has a Moto G5 plus too with everything stock and VoLTE working.
If I backup everything on his phone via TWRP and use that backup file and restore it in my phone, would it work? I'll find out tomorrow.

Bought a used N900v with TWRP installed and no 4G signal just 3G

I have 2 N900V phones with Alliance roms with safestrap on both. , wifes phone has a a bad switch so i bought a used N900V on Swappa. The phone came with TWRP installed so i flashed Alliance rom and everything works on except it is stuck on 3G. have tried most suggestions i could find and nothing works. So i thought it might be the rom, thought i remembered reading some where that Alliance rom may not work on TWRP. I installed Android 8.1]LineageOS 15.1 which works ok but still no 4G. The phone has a 4G back cover and model numbers are newer than my other 2 phones. Any ideas? Thanks for any help, my wife loves this phone Also i tried my sim card and both sim cards are new.

In setting about phone what is the baseband?
Thank you for your response. The new phone Baseband is N900VVRUE0F1. Both other phones are RUCNC4
I am not sure how TWRP works , is it overlaid on factory rom like my other phones which have safestrap ?

TWRP replaces stock recovery if you're not using safestrap or bootstrap and the custom ROM replaces the factory ROM. Does the new phone have an unlocked bootloader or is it using safestrap? Which custom ROM are you using.

If the it's unlocked you may see a unlocked pad lock on the screen, after boot or reboot. Also if you boot into download mode and wait a few minutes a list of text will show up, one line will be " Developer Device ". If it is unlocked.
Read this, ( all of it, its short )it will help you update TWRP.
https://forum.xda-developers.com/verizon-galaxy-note-3/help/trouble-flashing-custom-rom-t3887320
Alliance ROM looks old (Android 4.4) from what I can find. Your baseband is for Android 5.0 or higher. After TWRP update you will be using HLTETMO ROMs and a lineageOS ROM like this one.
https://forum.xda-developers.com/ga...eageos-15-1-hltetmo-unofficial-t3829154/page1
Or one of the other ROMs here:
https://forum.xda-developers.com/galaxy-note-3/development
May be best for you. Read the first post in the tread of any ROM you want use. If you have a problem with a ROM use search in that ROMs tread, most questions have already been answered. You can also ask me here for help. Good luck and always make a backup before making big changes.

Thank you for the links, Bootloader appears unlocked as i get the custom unlocked padlock when it boots. I have 3.2.3-0 TWRP already and i flashed the 15-1 Linage rom and it works fine . My main problem is no 4G on any rom. Do you think i need to update or change baseband? Thanks again for the help.
I have the same issue except I get No service after 1 reboot or any twrp backups.

Your baseband is OK. Did you do a clean install and what does the status bar say for the cell signal?

Try turning the phone off for a minute and then back on. I've had a no signal problem a few times, reboot and/or power down got the signal back.

Im starting to believe my issue is I have a Verizon note 3 board in a sprint phone I put the Verizon back plate back on
---------- Post added at 08:35 PM ---------- Previous post was at 08:29 PM ----------
Also when I did get service 1x-4g the network name was "roaming indicator off". For maybe 2 minutes it stayed " Verizon wireless"
I just remembered that all touch wiz Roms do the same thing to me. Also for some reason I can't flash stock based Roms. I'm getting a little worried about my note 3

I would make a full backup and try a custom ROM that's not a touch wiz ROM ported to note 3. It may fix the phone and if not restore the backup.

I almost think you have a hardware problem. The only way to be sure is to go back to shock, but it's a pain to root, unlock the bootloader and install TWRP again to get back to using custom ROMs. I let you know if I think of anything else.

My name is actually Mike. I live on the edge of a small city named Zachary. Good luck with your phone.
Thanks for your help Mike!
Well i am down to hardware issue, Verizon is telling me there is an issue with the 4G antenna and it is a different than the 3G antenna.
Does anybody know if this is true and if so where is the 4G antenna? I know there is an antenna cable between 2 contacts inside, does it handle
both signals? Thanks again for all your help and time.
