[4g fix] on Fulmics Rom for verizon VS985

Four things to note before proceeding...
1. This only works for users having vs985 model outside the US or not on verizon network.
2. I'm beginner im not responsible for any harm to your phone , I'm just sharing what i did to attain 4g services.
3. May be you already know all the things in the post but it can be useful for beginners like me .
4. Sorry for the english as its not my native language.
So Hi guys i installed this rom and as usually i was not getting any 4G or lte network.
Then i go to my network provider's website to check on which Band or frequency 4g services are active. ( for this i just googled 'idea 4g band' and i am redirected to my network provider's website. Here 'idea' is the name of network provider.)
So i found that in my region 4g services are active on Band3
Different careers use different Bands to provide 4g services such as band40 , band17 etc
Then i go to phone's hidden menu by the Advanced Menu of Fulmics Tweaks.
In hidden menu i select Modem Protocol > LTE Band Selection
There i select Band3 but i got "Fail' message on screen , however when i select band4 it gave me a 'success' message.
It means on my phone band4 is active but not band3.
All this information of Bands are stored in Modem or Bootstack section of our phone.
May be fulmics rom is having a band concerned with international rom So now i need a modem on which Band3 can be activated by going to hidden menu.
So i just flashed 35b Bootstack compiled by @xdabbeb.
Which can be found in this thread http://forum.xda-developers.com/verizon-lg-g3/development/xdabbeb-s-vs980-2-0-0-t3231279
After flashing when i tried to select band3 in hidden menu it gave a 'success' message . It means Band3 is activated on my phone. And now when i searched for all networks in Networks Menu of Phone Setting. I got my network listed and i successfully registered on it. And got 4G NETWORK.
So first of all you should know on which band your network is working and then try flashing different bootstacks on which your 4g Band can be activated.
Flashing wrong Bootstack can brick your phone
""Do not flash any bootstack above 35b. Custom roms are still not compatible with bootstacks above 35b""
You can try 24b , 12b. (But im sure only about 35b as i tried only this)
Again I'm not responsible for any harm to your phone. Use your mind and search thoroughly before taking any step.

Hi there, thanks for the info. What area are you in and where did you find what band you needed? I have tried numerous times with all the bootstacks and never had consistent 4G.

@mopartonyg
I'm in India and i just checked my career's website to know which band they are using. However in USA Verizon wireless uses Band12 as Primary Band and Band2 , Band4 as Secondary band to strengthen the signal in densely populated urban area. So if you are verizon user in USA band 12,4,2 must be activated. I can't say anything about consistency as it varies from place to place.

Actually Verizon uses band 13 for it's primary along with bands 4 and 2. Not having any luck getting data to work on Fulmics with this method. I select band 13 and band 4 (as band 2 is not in my area) yet even with that I still can't get data at all on Verizon with Fulmics.

same boat here... actually the only band I can get working is 4. I have to assume the design of the international rom with the band they are designed around, just don't play nice with our CDMA harware/modem partition. I would suspect that the international roms would require some engineering for them to really work properly. not sure if just porting them over and chaning settings is going to get the job done. perhaps someone more intelligent than I could share some light, but there certainly is a conflict with how these roms communicates across the CDMA bands in the US

One thing i noticed here... that only Verizon sim users are facing problem regarding 4G whereas other international users like me ( and some of my friends in China are free to select any network ). So may be verizon is creating restrictions as when i was on Stock vs985 verizon Rom ( unrooted) , i was not getting any official ota updates. It always says your software is up to date. But then i found a statement in Verizon's website that you will not get any official updates if you are not having verizon sim.
So verizon knows what Rom and what sim we are using.

A couple of good approaches to the issue. Although it needs to be noted 4G is directly related to the band on each carrier (VZW, TMO, etc) See Below
Carrier 4G LTE Bands Frequencies
Verizon Wireless 2, 4, 13 1900, 1700 f, 700 c
T-Mobile 2, 4, 12 1900, 1700 def, 700 a
Sprint 25, 26, 41 1900 g, 850, 2500
Europe 3, 7, 20 1800, 2600, 800
If a specific ROM cannot be set to the correct bands above, it would make sense to me that Verizon wouldn't work in Europe on a stock VZW ROM. It would not be able to use the channels in Europe.
And vice versa, that Verizon wouldn't work in the states on an international ROM in the US. Whether the Verizon SIM is blocking that band, or the design of the ROM, would be a better question for the developers.

Warid's approved devices will definitely work with Warid's LTE network. For our "Warid LTE Approved' devices please visit the "Warid's LTE devices" section. You can also purchase LTE devices that support 1800 MHz (FDD-LTE Bands 3) from other sources. However, Warid doesn't take responsibility for these devices if they do not work on Warid's LTE network http://www.waridtel.com/lte/faqs
So it makes sense that if BAND 3 works international (see above) that you get 4G

The one thing I noticed after activating bands 13 and 4 (with the proper VS985 35B bootstack) in the hidden settings is when I searched for my network under network settings it does bring up Verizon but it fails authentication. So it's like there is something missing in Fulmics ROM itself that would get it to where the ROM will work with Verizon's network. So is it a matter of lifting whatever files from say 47A/47B into Fulmics that have the Verizon VS985 specific info to get it to work perhaps?

I think now its not a matter of bootstack. Because even when Required Band is activated we can't register to the Verizon. Xpirt mentioned in a post that he is working to resolve network issues in Verizon models. We can hope that this problem will be solved in next version However xdabbeb shared that the 47A modem won't work without the corresponding 47A secondary bootloader (sbl1). Unfortunately, the 47A sbl1 doesn't play nice with the last bump-exploitable Android bootloader (aboot) we have from 12b. If you use that pairing, you'll put your device into 9008 bulk mode(Hard brick).

The good news is we do have 47A ROMs that are using the 35B modem so there is potential that Xpirt could use that as a source for a fix with the authentication issue. So @xpirt if you need anyone to beta test fixes my VS985 is ready to help!

This is good to hear and I second that!
Looking forward to getting it fixed and use it as my daily driver. It would totally be worth a big donation, thanks to everyone working on making this available to so many.

Great discussion towards the development of the International ROM's for our VS985. I was able to get 4G with Andy's 30A ported ROM...although the signal bars never came up on my phone, I was able to get the 4G speeds. I noticed that the APN XML was filled with Chinese... So for whatever reason and way, my phone was able to grab "somebody's" 4G tower. I'm hoping the RIL (Radio Interface Layer) and libraries were pulled over and perhaps this could provide some more insight to @Xspirit

I am on BlackSoulxxx latest LG G3 Tekcafe v5.3 D85530A-Full G5 ROM. Here's what I did to get the bars with 4g data. I tested it out in areas where there is no cell service and in areas where there is 1x or 3g and the 4g came back. I even made a backup of the ROM wiped and installed another marshmallow aosp rom and others. I then went to restore BlackSoulxxx ROM and 4g signal still came back.
Steps I did.
1. Tot'd back to stock 10b and rooted and installed twrp.
2. Flashed LG_G3_Flash2BackupEFS.zip of the 10b rom.
3. Wiped stock 10b and flashed the 10b G3_EFS_Flashable_Restore.zip that was created from the the LG_G3_Flash2BackupEFS.zip.
4. Flashed BlackSoulxxx rom and after it booted up I had signals but not data until I entered the Verizon APN manually see picture of what to enter. If mobile network is greyed out flash 35b bootstack.
5. I entered the verizon APN and selected CDMA then global I got the 4g icon with signal bars I changed the icon with a buildprop edit.
I just don't get signals while in 1x or 3g but data does work still and it will get 4g again if your in a 4g area. The phone does say T-CDMA 64. Here's a https://drive.google.com/file/d/0B-EyVOQK1xDAa0VmbERXcUlrV1U/view?usp=sharing to change it to Verizon Wireless courtesy of @xpirt.

Great job posting your step by step instructions. I've been able to achieve all of the same on a host of international ROMS however with a couple of caveots. I can either have SMS/MMS working properly, or break SMS/MMS and have internet with signal bars. Question about the file above. This will just modify the header, or will it specifically put you on the Verizon network?

Sprint HTC 10 on T-Mobile?

Does the Sprint variant work with Ting GSM (essentially T-Mobile towers) if you SIM unlock it following the SIM unlock tutorials? Or would it require more than that? I looked on HTC's site and its shows the phone has all the same bands for the Sprint version and T-Mobile version. Does anyone have a Sprint version working with Ting or T-Mobile?

I believe it does if you change your cid and flash it to the unlocked firmware. There are threads everywhere on how to do this, make sure to check the un-carrier branded HTC 10 xda site.

I run a Sprint device on T-Mobile. Works perfect with the exception of WiFI Calling which I am currently trying to get working.
Simple way is to unlock SIM NV method, load custom recovery, load latest Viper ROM, on AROMA pick the proper base install MM or N and Choose T-Mobile for carrier and that's really it man. the LTE bands are already all there, reason why I say Viper after the unlock is because other people including me had trouble getting data to work on stock Sprint MM. Flashing Viper solved that beautifully.

The only thing that sucks is you will be missing WiFi Calling which to me was a little annoying. I have tried everything, I went as far as S-OFF (kinda of a waste of $25) installed multiple firmwares (T-Mobile stock with Sprint radio, etc), different rom's, so far nothing, it seems tied to the actual us unlocked/t-mobile radio which as we know isn't compatible with the Sprint variant. On the plus everything else works including VoLTE.

xt1644 (us) moto g4 plus radio, which one???

I am running Official Lineage for the Moto G4 plus , I currently have the latest radio (M8952_70030.25.03.62R8952-05.30.R), this must not be the right radio for the xt1644 (us) version on Verizon (cdma). It (or the rom) thinks I have 2 sims. The 1644 version has only one sim (a cdma/gsm,/lte, etc. ) radio.
The phone is sometimes flaky, sticking on cdma or LTE, have to go into the hidden menu (Phone info), to get it to switch sometimes.
Also Phone-settings-calls (phone.android.com) always force closes when trying to open that submenu.
Droidphilev said we may need to flash this radio: athene_MPJ24.139-64_radio_M8952_70009.08.03.45R+FSG-8952-03.68.zip
Does anyone have any experience with the xt1644 specifically? I know most of you are in Europe/asia and have GSM.

Here is a link to all the radios

I lose LTE when I flash any of the zip file radios in twrp. I have to wipe, and reflash the stock Nougat rom through fastboot to get LTE back. Fortunately, I can restore my data backup through twrp and be back up running pretty quickly.
I have noticed that it thinks I have two sim slots, when I have only one. And when I try to open phone/settings/calls to set up voicemail, com.phone.android force closes, and sometimes it asks me to choose sim card 1 or 2.

Data will not work after flashing G935U Firmware on G935V

So Im looking for a way to enable native tethering on my phone and after a lot searching I flashed the G935U firmware. After flashing the G935U firmware on my G935V, my data stopped working. Call and text works fine but no data. It doesn't even show the 4G LTE symbol in status bar.
I am currently using Straight Talk BYOP.
Any help would be much appreciated and thank you!

Thats the crazy part! I cant edit it after flashing the U firmware. But the APN settings are the same from when it was still on the V firmware. Its just now the 4G LTE doesnt work. I downloaded some 4G enabler from the play store that took me to some hidden settings to change between GSM, CDMA, and about 12 other variants of similar nature. After doing so the only one that worked was the CDMA (prl) which activated 3G network. But LTE CDMA (prl) didnt work which was what it was on I think.

add a new APN with tour settings. emable it... and try global mode

Nope still no go...its not even showing 3G at the momemnt

I tried every apn/preferred network type combination and wasn't able to get anything better than 3G. So I just got done flashing the G935V firmware back and now 4G LTE is working. Anyway I can use hotspot on G935V firmware?

SOLVED!
So after contacting straight talk it seems my APN settings where to blame.
Upon opening the APN, I had to change APN from "vzwinternet" to "tracfone.vzwentp." Then save and make sure network mode was set to LTE/CDMA instead of global.
I noticed it returns to default "vzwinternet" after flashing any firmware thus making me have to put it back in. But that's no problem at all. Everything is currenly working and I now have tethering THANK YOU FOR THE HELP

G935V to G935U for AT&T
I have the Verizon S7 Edge G935V working on straight talk with their AT&T sim.
Had to change from CDMA to GSM then add the new APN settings.
The problem I have is the G935V doesn't have LTE band 17 which is used in my area.
My Nexus 5 with same sim using LTE Discovery app confirms band 17 but with S7 Edge G935V
I don't get it but a different connection and its very weak.
I would like to give this G935V to G935U a try. My S7 Edge G935V has Android 8.0
I have downloaded ODIN, Samsung S7 Edge drivers, and G935U w/Android 8.0 (AT&T) July 24, 2018
Has anyone done this recently on a G935V with Android 8.0 on it?
Will I get LTE band 17?
Do I loose any CDMA capabilities should I want to try it?
What's the down side of doing this?
How would I continue to get updates?
Thanks,
Ken

Strange Network Issues With Unlocked SM-G935P (Sprint) on MetroPCS

Hey guys, I could use a little help here. I've done some firmware flashing on phones years ago, so I'm not a total noob, just haven't needed to in a long time.
Anyway, I recently picked up an unlocked Sprint S7 edge (was a really good deal) and I'm trying to use it with Metro now. The issue is this. If I set the network to GSM mode, I can make phone calls just fine, but data is totally not functioning. If I switch it to LTE/CDMA mode, the data works beautifully, but I can't make or receive any phone calls. It just instantly hangs up if I try to dial out or goes to voicemail if someone calls me.
I've activated the IMEI with my carrier and verified that the phone is indeed unlocked. I'm guessing this is just some annoying Sprint bug put in there to make the phone not work right on other providers. Any ideas what needs to be done? Do I need to run a third-party ROM, flash a different modem to it? Something else?
I really appreciate any tips here.

What firmware is the phone running?

Hi Ivpre,
Thanks for responding. The phone is running Software version G935PVPU6BRD2, baseband version G935PVPU6BRD2, it's HW revision 7.0 and Android 7.0. Kernel version is 3.18.31-12623509.
I've tried using a few SM-G935U ROMs but they all have failed so far and left the phone in a boot loop. Only by reflashing a Sprint ROM am I able to successfully flash it.
I assume I'm just not selecting or finding a ROM that the same or newer version, as I've read about the downgrade issues with the bootloader. Any idea how to match one? I'd be fine with pretty much any ATT/T-Mobile/Metro ROM since that should fix my issue for the time being. A factory unlocked ROM would be nice though.

I have a T-Mobile Sim (same network Metro uses) in my unlocked Sprint S7 Edge. Network mode is set to Automatic and everything works fine.
Did you Add the APN for T-Mobile? I had to add the T-Mobile APN https://support.t-mobile.com/docs/DOC-28006
And the ALSO add a second APN named internet, with no other values changed. The 2nd one is the one selected, not sure why, but it works that way.
I would like to flash a T-Mobile Rom or the U Rom but they are on Baseband 4, which will not work since our phones are now on Baseband 6(5th number from the right in the firmware version.)

Did you try changing the APN settings?

So you are using the Sprint firmware on T-Mobile? Everything works well? I'm thinking of jumping to cricket this summer, but one phone is stuck on b5 (the other is still rocking 4), so I was a little worried. So basically you just put in the SIM card and added the APN's?

Yes it was working fine with a T-Mobile Sim card and edited APN's. It is now back on Sprint because T-Mobile coverage is poor/non existent inside my work. I will be porting one of my SERO lines to T-Mobile but keeping one with Sprint. T-Mobile only uses Band 2 and 4 where I live, If you live somewhere that has band 12, it may not be unlocked in the Sprint Firmware.
