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:

Hey guys having a bit of problems. I tried the LTE enabler since we have it where I live now. I got the zip from a popular thread in the general section, I asked in there but figured this warranted it's own thread. I had no bars, so I switched back to the latest radio and now I'm permanently stuck with zero cell reception of any kind. I've tried everything I can think of to fix it, I flashed a new ROM, restored a backup, I even flashed the stock image from Google, and did each piece individually in a terminal, so I know I flashed the radio and I'm STILL not getting any service.
Today, I went into Telus to get a new sim card because I thought that was the problem, but that didn't help at all.
Please don't tell me I'm screwed. And yes I did try the disable zip multiple times.
I've attached screenshots of my APN and mobile network settings. Trying to join the network results in an error message.
Anyone? Would greatly appreciate some help as I'm stumped and this is my only phone.

My apologies if I was unclear in my original post, I've tried that. Multiple times.
i followed this thread, and LTE worked like a champ. Though i did not stay on a stock ROM, u personally used DirtyUnicorn rom, but still followed steps to edit the build.prop manuall, and flashed the radio .33. You must use the correct apn's. For US T-Mobile, there is a old epc.tmobile.com apn that does not get LTE reception even if you have a lte equipped device, i had to use the fast.t-mobile.com apn, im sure Telus has an updated apn as well.
http://hippowise.com/how-to-permanently-enable-lte-on-android-4-2-2-nexus-4/
BTW, i dont think it matter what android version your in, cause when i did this, i was on a stock 4.2.2 and it worked, and then i flashed over to the DU ROM, and made the same edits since i used a new rom, and it worked perfectly again. Make sure to press *#*#4636#*#* once all is set said and done and put the netowrk setting to LTE/GSM auto-prl. Not sure why the option for LTE/WCDMA/GSM is not available, maybe someone could help with that one???????
One thing most people forget is that your provider plays a big part in your LTE service. If your sim/account is not provisioned for LTE you will never get it.... period. IN my case I came from an android phone that had no LTE support so it was never provisioned on my account(att). And since the nexus wasent shipped with LTE support or part of att' s LTE phone lineup...they refuse to add LTE support for my nexus. The only way for me to get LTE provisioned on my sim is for me to buy an att LTE compatable phone....then I could just use the sim in my nexus. Try flashing a stock Google image, see if it helps.

I recently got a Verizon S5 from a friend of mine to use with my T-Mobile SIM card. It had stock 4.4.4 with build NI2 so I rooted using the NCG stock and towelroot before flashing back to NI2. Everything worked as expected and I was able to make calls and whatnot.
Now I decide I want CM 12.1 on my phone and begin the process of getting BusyBox and SafeStrap installed. Again all is going according to plan including the backup of stock ROM.
I wipe and flash CM 12.1 and get into a boot loop, so immediately I wipe again and restore to my previous backup.
Now I can send/receive texts, MMS, and my LTE works fine; but I can't make calls.
I've gone through all the steps to enable T-Mobile LTE through the CA Settings and manually enabling Band 4, and don't think this is related, but it might be.
I've reset multiple times, tried flashing CM 12.1 multiple times, and now I'm back on stock Touchwiz and am ready to shoot someone.
Specs:
SM-G900V
Version 4.4.4
Baseband is NI2

You might try flashing the NI2 kernel and if that doesn't work, the NI2 firmware.
So I just got a pop-up wanting to know if I would enable global mode. It had a dialer app icon but it appeared while I was in the messenger app. I said okay and now calls work. The only place I can find global network settings is in the network settings, so if anyone finds this with the same error, try re-enabling global network mode.

Verizon uses CDMA technology. T-Mobile uses GSM. All non-USA part of world is GSM, so maybe phone has both so that it can be used outside USA, but you have to enable Global to enable GSM. (Verizon, Sprint, and one other USA carrier are the only ones in the world to use CDMA.)
hey just a tip. it has nothing to do with your problem (well maybe it does) and sorry if you already knew but i was very happy when i found out. T-mobile roms work on these phones. I use Alliance 4.4.2 rom from the sgs5 t-mo section. Flashed with safe strap and it works great. I was having major issues when using the VZW roms. Like phone wanting to dial *86 for my voicemail then hanging up my phone call, or getting the 1x symbol constantly while in a call or just after calls ect. Now all i need to do is figure out how to put T-mo 5.0 roms on this thing....mehhh... i'm sure there's a step by step somewhere I just cant find it. Hope this helps if not I'll edit and put a thanks or thumbs up or something.
Can we install a t-mobile rom (900T) and flash the radio specific to 900V back so that t-mobile wifi-calling works? Can someone answer if they have done this?
Also will the band 12 on this work with t-mobile's new 700MhZ?

It works fine i used the alliance rom but you dont need to flash the modem file, even the wifi calling is working but since t mo recognizes it HSPA+ as 4g but when you connect to an actual 4g it will say 4g lte but you cant connect to t mo 700 mhz as it doesnt support that frequenc

I am using am gs5 verizon on a gsm network with lte band 3 and i never had problems with calling, i suggest you look for an app called Advanced Signal Status though you will need root so that you can change between network types

Looks like we may be stuck on CM12 or LP based custom ROMs my friend
To be perfectly honest, you're not missing out on anything, having run the same ROM of LP and of MM, there is no real difference in regards to performance and battery life.
Sent from my SPH-L720 using Tapatalk
This is really sad... I've spent 3 days flashing various modems and can't find nothing. Though, I'd point out my LP kinda behaves same as my M, when it's done loading apps after flashing, it ask to insert simcard (same like my M), but then I go change the network type to 3g and network returns on the phone. Tried with cm13 but nothing, does anyone know what could be wrong??

Yeah like my texting and data works fine it's just the calling that doesn't work, and I'm just like lost now and ran out of ideas, like when I go in the settings and go under phone info and it shows I'm connected to mobile network and IMEI info is still the same from stock ROM.
I'm stumped. The sim is working since text and data work.
Is the phone being used with the carrier that issued the phone or was the phone purchased outright and unlocked?

It was originally by telus Canada variant, but recently in Canada they made it free to get your phone unlocked under certain conditions, so I called telus and they unlocked it for me to be world wide, because my phone is actually so simaler to the US and European variant, on how they are built so I Flashed TWRP GT-i9505 on it and now so now I'm running XOSP-UNOFFICAL-20180114-JFLTEXX and everything works except calling, right now that's how I'm responding to this thread is by mobile data.
Yes, the sgh-337m (Canadian variant) and GT-i9505 are very similar but the radio bands supported by each model is different. Maybe certain radio bands need to be unlocked or enabled for voice?
You could try this website to check compatibility with a stock i337m ROM: https://willmyphonework.net/

I am using Freedom mobile is my current service provider, not the biggest company but they are growing. OK I'll look at that link
Did you modify the radio bands to enable AWS for Freedom? I know they are expanding their LTE network to bring LTE to phones that previously worked on 3g only like the iPhone 6s a1688.
Modify Bands? May you describe what that is and how? Because I didn't modify anything all I did one day was Flashed stock ROM via Odin from SamMobile and ever since them my IMEI hanged or anything

I think it may be a kernel issue. Is the phone running the kernel included with the rom?
I never actually knew the differences were between a Rom and a kernel? For a while ithought they were the same, hold on I'll take a screenshot of it.

Hello guys.
I have an issue since I decided to flash a pie rom, specifically simplix blue, have no idea if has something to do with that rom.
I used to have LTE as normal and everything was good. Since I flashed a PIE rom I lost LTE. I tried going back to stock and LTE is still gone. Had tried flashing some modems, did not work either. Tried several radio combinations on *#*#4636#*#* did not work.
Any suggestions? I am on Tigo Colombia as carrier and never had this issue before across several xiaomi devices that I have had

https://forum.xda-developers.com/lenovo-p2/how-to/enabled-4g-ca-p2-t3707584
As soon as you finish adding the band, install network signal guru, provide root admin rights and then select on the 3 dots at the top right corner lock bands, select lte and pick up the band missing and reboot.
