Thanks for your valuable time.

i tried to manually turn on the radio but it is automatically switching off.

it was working fine one month ago, i dont think it's a hardware problem because i tried flashing roms many time and that messed the modem partition i guess. Where can i find v10 modem?
[Verizon LG G4] steadfasterX:
sorry just remembered the vs986 has a different version naming. what I meant is just it should be Lollipop based. I guess LP based starting with a 1 (e.g. VS986-13A) and MM ones with a 2 (e.g VS986-2BA). I am not 100% sure though but it looks like.

you have to find KDZ's which are Lollipop and extract the modem partition with SALT.

example site: https://lg-firmwares.com/lg-vs986-firmwares/#tab=firmwares

there are others but you have to ask google for those.

btw: I someone help you out on XDA consider to use the thanks button on useful posts. not just mine it goes for any ;)

[Verizon LG G4] Ashish_117:
Can you explain the difference between modem and baseband and what is happening when i flash modem followed by baseband.

Thanks

btw: i will break your thanks button xD
[Verizon LG G4] steadfasterX:
modem (aka firmware) contains firmware (thats why many ppl mix things up here). Example: sound blobs, camera stuff and also the baseband needed to bring up the radio/modem properly.

as long as you do those tests with other modem partitions on an UsU compatbile ROM (like this one here) then there is

no

need to flash the UsU baseband package. tbh that would make your tests useless so do not do it.

The baseband package is fully explained in the UsU thread ( https://xdaforums.com/showpost.php?p=75817534&postcount=3 )

Wow thanks for the great info, by the way i will post my status of network service after flashing different modems, hope it works.

I would like to learn more about roms and interested in building an aosp Pie for G4.
[Verizon LG G4] EsperaKing:
Hello guys...

I think I discovered something. For those like me trying to flash Oreo roms directly from MM on their devices... You may get boot loops after flashing the Rom...

The trick for me was to flash nougat stock first and then flashing Oreo. This way I can have Oreo rooms booting fine.

But now am facing :

* network issue.

* no sound (can it be fixed by flashing Dolby?)

* camera not working too

I don't know how to get the network on Oreo as I have network on MM...

I'm out of ideas as I've tried anything

And modem.bin causes bootloops on nougat or Oreo...

Hope this help someone...

[Verizon LG G4] Ashish_117:
Tried Everything still its not working. I cannot start the radio. is there any way to restore all partitions?
[Verizon LG G4] Ashish_117:
Hey can i try restoring all partition of other VS986?
[Verizon LG G4] steadfasterX:
You can but you have to skip several partitions otherwise you will brick or loose your imei etc
[Verizon LG G4] Ashish_117:
So i have this modem/baseband issue that get no service after 1 day or few restart so should i try to restore all modem/baseband partition from a working vs986? If yes which all partitions should i?

Thank you

EXPLANATION

I am from india, I bought this phone from a guy. At first whenever i insert an Indian sim It will show sim not from verizon but some 2g sims like vodafone works even though it shows sim not from Verizon. So I UsU'ed the phone flashed baseband -> Flashed MM modem and magisk, it work fine for a month then after many reflash and installing masgisk caused No Service and I tried different ways to fix it but then came a new issue after fresh install os, the network service works only for one day. Tried everything I can still not use.

Here are list of guide I create to flash the OS to get network works but only the last method works now and it has the one day Network Problem::

------------------------- 1st Method ------------------------------

goto bootloader

fastboot erase modemst1

fastboot erase modemst2

Flash MM modem no matter the os Nougat or Oreo

format data

Flash OS

goto bootloader

Flash UsU kernal for specified OS. —> Fastboot flash boot boot.img

Flash gapps

flash magisk - - network wont worker after flashing magisk

*************************** 2nd (If First method does't work) *************************

fastboot erase modem

fastboot erase modemst1

fastboot erase modemst2

format data, cache, system

flash stock rooted_vs9862ba OS

format data, cache, system

flash Lineage Os

flash gapps

And network will be there

———————————3rd method if above method doesn’t work ———————————

flash stock rooted_vs9862ba OS

goto bootloader and erase only modem

fastboot flash modem modem.image (28a modem extracted modem.image)

twrp wipe system, data, cache, format data

flash lineageos

-------------------------------------- End ----------------------------------------------

Note: Only the 28a modem worked for my sims before.

[MENTION=5545101]steadfasterX[/MENTION] [MENTION=7806151]ANDROID2468[/MENTION] Kindly help!

If it's a hardware issue what should I replace?

Thank. you.
[Verizon LG G4] Ashish_117:
[MENTION=5545101]steadfasterX[/MENTION] It is my primary phone ?!
[Verizon LG G4] ANDROID2468:
ok so did you restore those partitions with the steps I gave you?

one question. why are you erasing modemst1 and modemst2?
[Verizon LG G4] Ashish_117:
Yes, i have done that steps but still the radio cannot be turned on. The only way it can be turned on right now is the 3rd method i have mention but it wont last long.

I erased the modemst1 and 2 because in the instruction of LOS installation it is said that to clean flash MM modem, so I did it(i was not sure if it is needed).
[Verizon LG G4] steadfasterX:
When the signal disappears after one day:

Only do a

factory reset

(in TWRP or ROM) & reboot

-> Brings this the signal back ?

If not:

format

data in TWRP and reboot

-> Brings this the signal back ?
[Verizon LG G4] Ashish_117:
I Flashed KDZ using LGUP Tool, I will try to UsU again and post the result here. If it exists again we can confirm it as a hardware error right?
[Verizon LG G4] steadfasterX:
No. My mentioned actions are to identify a possible workaround but for this I need to know where the issue occur and why it does not appear on the first day.
[Verizon LG G4] Ashish_117:
I flashed kdz and UsU'ed the device and followed the steps still no signal not even the one day signal fix. But it says registered on a network and have the sim toolkit app. the Radio is off and if will turn off when we try to turn it on.
[Verizon LG G4] Ashish_117:
[MENTION=5545101]steadfasterX[/MENTION] Can you find me a solution?

This one is when Airplane mode is turned on and off: https://bpaste.net/show/c8c41129450f

Thanks
[Verizon LG G4] steadfasterX:
well the best one who could help here is your provider but I bet you will not be able to reach someone with technically knowledge who even understand the issue.

do you have tried to select the network operator manually? do so and follow exactly the guide for taking the logcat: https://bit.do/logcat

follow ups to this should be handled in an own thread though or just IRC - up to you

Calls & texts no longer working

Was having terrible battery drain issues with LG G4 VS 986, tried new batteries, nothing worked.

As a last resort I tried flashing a custom ROM: LineageOS 15.1. I did this using FWUL, SALT (for UsU), and TWRP via this thread.

LineageOS up and running, battery drain issue solved! WiFI & mobile data both work. However I can no longer send/receive calls and texts.

I’ve tried resetting network settings, taking out & reinserting SIM, even had Verizon reset my number to my device. Nothing seems to work.

Of lesser importance: camera and flashlight also down.

Help?
[Verizon LG G4] steadfasterX:
the last one is absolute NOT unimportant. If camera and sound does not work properly then there is an issue with your modem partition.

Try flashing the modem partition of your SALT backup BEFORE UsU. Do not flash the baseband package. Boot and wait 5min at least, change to GSM/2G and wait again at least 5min, reboot and wait again 10min. If it still get no signal try the same with all other network types as well.

.-
[Verizon LG G4] Asusbricked:
I already UsU'd since that was first in the Installation instructions. I have ARB 2 so I may be able to revert the UsU, is that what you're suggesting?

Before seeing this reply: I read in UsU FAQ #5e (re: no cell service) to first try flashing UsU kernel for your ROM - still no calls and now mobile data no longer works (SIM card not recognized). I swapped out the SIM, did not work.

I continued following #5e suggestions: next flashing the baseband package (still no calls) and then the modem partition of my backup. The problem persists.

I had LTE mobile data working before flashing the UsU kernel, so close.

This is an older G4 that I'm comfortable losing if I can't undo what I did. Total noob, enjoying learning the process even if I mucked it up.
[Verizon LG G4] steadfasterX:
No I said you should take the modem partition of your backup which you made before you UsU'd the phone

afaik the vs986 custom ROMs are not fully working in terms of cell service. I know there are some others for which it works and others not. I am not sure the main issue for this but I started to update the proprietary blobs a while ago for the vs986 to see if that changes anything. Still no guarantee though so you should either wait for this or going back to stock e.g. with the excellent guide by [MENTION=7806151]ANDROID2468[/MENTION]

Hello everyone... hope you doing well...

Well am back again lol

I don't know if this is the reason why when I flashed Lineage, I didn't have network... Well the thing is that I don't have an imei on my phone. *#06# gives me no imei... There is the original imei under the battery but not in the system... Network is still working with even LTE sometimes... Any idea of how I can fix this?
[Verizon LG G4] ANDROID2468:
What carrier are you using right now?
[Verizon LG G4] EsperaKing:
I am using "MTN" don't know if yo know it... It's a local carrier here in my country....
[Verizon LG G4] ANDROID2468:
Did you flash the baceband package?

What FW where you on?
[Verizon LG G4] EsperaKing:
Yes I did flash the baseband package...

Am on the stock 2BA...

I will be flashing the one you released later but for now am trying to fix IMEI before...
[Verizon LG G4] ANDROID2468:
Yup that's your issue, I will give you a flashable modem. later about 45 min from now I'm kinda out right now and my phone is about to die.
[Verizon LG G4] EsperaKing:
Nice thanks bro..
[Verizon LG G4] ANDROID2468:
here you go. flash this in TWRP

https://drive.google.com/open?id=1WArxQBjDgn10tofIyroGJ8K-QmlHadj0
[Verizon LG G4] EsperaKing:
I flashed this in TWRP but my IMEI is still 0 in phone informations... Am about to flash your revamped 2BA firmware... I will flash your modem on it maybe I may get my imei fixed...

Oh wow, you changed this boring boot animation from VERIZON... That's nice!!!
[Verizon LG G4] ANDROID2468:
If the IMEI is different then the one on the back of your phone then tell me
[Verizon LG G4] EsperaKing:
The imei is still 0
[Verizon LG G4] ANDROID2468:
ok try this... (this was from [MENTION=5545101]steadfasterX[/MENTION] on page 3)

... but when you see a different IMEI in the dialer (*#06#) it means your misc partition is likely screwed (I had the same issue while my UsU journey when flashing a stock firmware).

try this:

write down the full IMEI you see in the dialer ( back of your phone)

do a SALT basic backup

open a terminal in the backup folder

type:

strings misc* | grep THEIMEIYOUSEEINDIALER

(replace the word "THEIMEIYOUSEEINDIALER" with the IMEI you saw in the dialer or the one on the back of your phone)
[Verizon LG G4] aka_bigred:
hey [MENTION=8339641]EsperaKing[/MENTION] - did you ever get your VS986 working with Lineage ROM? I've been running 2BA stock on my USU'd VS986 and the battery is unbearably bad. I want to try Lineage, but *must* have mobile calling working.
[Verizon LG G4] EsperaKing:
Hey bro!!! Wassup? Well I've just got it booting but there is no network. It may work on yours but it didn't on mine. I've stated what I did to get it flashed if you encounter issues...

But as you know... ALWAYS TAKE A BACKUP OF THE CURRENT ROM ON YOUR LAP OR EXTERNAL STORAGE!!! before anything else...

Goodluck!
[Verizon LG G4] SomeDooD123:
Been using this on my VS986 for almost a week now. Been working great on T-Mobile. Thanks so much for all the hard work getting this to our VZW G4's.
[Verizon LG G4] SomeDooD123:
Hello,

So I finally got around to trying to encrypt my phone and seemed to have lost the ability to connect to my cell signal. Phone says it has no SIM card. Is this a known issue? Tried to search on this thread but didn't find any mention. Also saw there was a new April build, might give that one a shot later this weekend. Was also experiencing video lag when playing any 1080p video, but saw you posted a possible flashable fix, will probably give this a shot later today. Thanks again for all the hard work.

Edit: Nevermind, the no cell signal with encrypted phone went away on its own after a couple of restarts. Have yet to give the video lag fix a shot. Hopefully soon.
[Verizon LG G4] Prayerwimp:
Hello, I am having trouble getting my sim card and my sideload to recognize. Also I cannot get the Google Pico to flash. Originally I installed the Aroma but then wiped and now cannot get Pico to flash. the error is: failed to map file '/sdcard/open_gapps-arm64-8.8-pico-20190418.zip' error installing file '/sdcard/open_gapps-arm64-8.8-pico-20190418.zip'. I have the LineageOS installed.
[Verizon LG G4] ANDROID2468:
Go into the advance wipe opinions in twrp and format the system. after that flash your rom again. About the Sim card not working, it totally depends on what carrier you have if you can get phone calls working or not. If you flashed the baceband.zip, flash this in twrp to get your sim card to be recognized. If you have Verizon the only thing that works is data. No calls or SMS messaging.
[Verizon LG G4] Prayerwimp:
I did not flash the baseband.zip as the instuctions said if I use a USU rom I would not need it.

Is this going to fix the Sim card or the side load, or the Google apps?

So, if I get a new Sim card for say Straighttalk it should recognize it?
[Verizon LG G4] ANDROID2468:
Sorry I didn't clarify, that is the 2ba modem. I would flash that and see if it changes your sim card issue.

As with the gapps issue, just reinstall the rom. That will get rid of the old gapps install and just flash the gapps you want after that.
[Verizon LG G4] Prayerwimp:
Do I need t remove the modem that I have installed? If yes, then how would I do that?

About the Gapps. I just installed the nano version.
[Verizon LG G4] ANDROID2468:
No you don't have to format the modem partition. It gets to overwritten by this installer.

HELLO

My little sister played with my mobile and entered a pattern to the lock screen (S8+) and no longer can I access mobile again after reboot :(

I have google account email but I'm not sure that is logged on mobile

Is there a way to bypass without wipe data and factory reset ??

:confused:

WORK OF 10 YEARS WILL BE ERASE BY THIS DATA RESET !!!!:crying:

HOPE I WILL SEE SOLUTIONS TO MY PROBLEM

REGARDS
[Samsung Galaxy S8+ Questions & Answers] andy_n_:
just enter an invalid passwor a few times, and it will take you to the forgot password page.

You can then enter your google account email, and proceed to unlock it with your google account password, or create a new pattern. ( You have to have a google account created when setting up the phone, but don't need it logged in on mobile).

If you perform a factory reset, you will still need your google account email and password, as those are saved to a protected partition on the phone, and you cannot erase that. This is to prevent people from stealing phones.

Team Win Recovery Project (TWRP), is an open-source software custom recovery image for Android-based devices.It provides a touchscreen-enabled interface which allows users to install third-party firmware and backup the current system, which are often unsupported by stock recovery images.It is, therefore, often installed when rooting Android devices.

What's new in 3.2.1-0:

* minui fixes (cryptomilk)

* Better android-8.0 compatibility in ROM trees (Dees_Troy)

* Fix missing library in android-8.0 (nkk71)

* Fix inconsistent SDCard naming (DevUt)

* Default to TWRP restore instead of adb backup restore to fix restore on fresh TWRP boot.

Downloads:

TWRP For J7 Plus

Installation:

•In your ROM, go to Settings -> About device. Tap 7 times on Build number to enable Developer options.

•Now go to Settings -> Developer options. (above About device).

•You need to enable OEM unlock, otherwise you might end up with boot problems or be unable to flash later on.

•Extract Odin_3.10.7.zip to your computer.

•Install Samsung Mobile Phone Drivers for Odin to find your device.

•Download .tar image of TWRP For J7 Plus.

•Reboot your device into Download mode. To do this, select reboot from the power menu and hold the [Volume Down] + [Home] buttons while your device reboots.

•Once you reach the Download mode warning screen, press [Volume Up] to continue.

•Open Odin and place that TWRP tar file in the [AP] slot without touching any other options, then press [Start].

•Hold [Volume Up] + [Home] buttons near the end of the flash, and keep holding them until you are in recovery.

To disable forced encryption and mount internal storage(/DATA):

(Note this MUST be flashed after SuperSU if you intend to root)

1. Boot to TWRP

2. Format Data partition using FORMAT DATA button under Wipe options.

(Note: This will wipe the internal storage)

3. Check DATA is mountable.

4. Install SuperSU (if root is required)

5. Install Boot Image Patch below.

Thank you so much

I had been waiting years for a TWRP for J7 Plus. Thank you so much. idk if this works or not but I will give it a shot once I reach home. Thanks again. Btw how do i use the verity patcher?
[Miscellaneous Android Development] Albe96:
Flash it from TWRP. ;)
[Miscellaneous Android Development] Recreation01:
thanks, it works perfectly! I hope more users can notice this.
[Miscellaneous Android Development] Albe96:
WOW.Maybe PM me with some screenshots! ? Glad to know
[Miscellaneous Android Development] PreferableBird69:
Questions

1. Do we still need to reflash the boot image after booting to twrp again to avoid encryption?

2. Where do we need to put the boot img and magisk/superSU files if we're going to wipe the data, won't that be deleted as well hence with the internal storage?

3. Lastly, will the sd card be read? Because in the other twrps I've tried both internal and extsd will not read or not mountable.

Hope you'll respond ASAP

Thank you :o
[Miscellaneous Android Development] Albe96:
Did you flash no verity boot image patch after flashing twrp and before booting back to rom? You gotta flash that. :)
[Miscellaneous Android Development] PreferableBird69:
I haven't tried it yet as I'm still not sure of the outcome of it. So what you're saying is that flash no verity first before fomatting the data?:confused:
[Miscellaneous Android Development] Albe96:
Just flash the no verity zip.then reboot the device.Then you're good to go what you want to do
[Miscellaneous Android Development] Recreation01:
1. No

2/3. SD Card can be read but I can't mount it on a USB. You might want to backup all your data.

---------- Post added at 12:09 PM ---------- Previous post was at 12:08 PM ----------

Btw can you develop roms for this device? I am sure many of us will be hype
[Miscellaneous Android Development] Albe96:
First off all I wanna know if TWRP is working or not? Secondly I don't own this device to work for it either I can but you have to provide logs(will be irritable).And I don't see many people for whom I can work.I mean these days,nobody like mediatek chipset devices...

Maybe you didn't set RW permission that's why USB can't mount ?
[Miscellaneous Android Development] PreferableBird69:
Okayyy thank you very much for the immediate responses guys highly appreciated:victory:
[Miscellaneous Android Development] PreferableBird69:
Hey guys any update from the official twrp of this device?
[Miscellaneous Android Development] Albe96:
LMAO No.This device us not official to TWRP yet
[Miscellaneous Android Development] PreferableBird69:
Y though:(
[Miscellaneous Android Development] Albe96:
Because the device isn't popular I guess
[Miscellaneous Android Development] PreferableBird69:
Hey so i tried flashing it and still my sd card won't be read sigh
[Miscellaneous Android Development] Albe96:
Did you flash the dmverity patch?
[Miscellaneous Android Development] PreferableBird69:
Yes ofc because without it my phone will be stuck. Anyways internal storage is still readable but I'll be flashing the dmverity always after installing something right before rebooting or else it won't boot. Thanks though:D
[Miscellaneous Android Development] PreferableBird69:
Can someone help me fix this problem please? Would much be very appreciated
