[ROM][UNOFFICIAL] LineageOS 20.0 [Android 13.0][JUDYLN] [Updated 15-10-2022]

[DanCS1995]

A special thanks to @EmanuelCN for work hardly on Device Tree, Kernel and Recovery, without it this Rom wouldn't be possible.

ABOUT LINEAGE:
LineageOS is a free, community built, aftermarket firmware distribution of Android, which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for LineageOS is available in the LineageOS GitHub repo. And if you would like to contribute to LineageOS, please visit Gerrit Code Review.

OrangeFox
fastboot-tools.zip
fastboot-driver.zip
fix-fastboot.zip (You'll may need this)

ABOUT GAPPS:
Does this Rom come with GAPPS?
No, it doesn't. It means you'll not have "Google Play Store" app or any other Google related service or application in it.
If i wanna use it, wich one should i use?
Make sure to flash the right one that matches to your current Android version, AVOID Stock packages, and the ones that contains "Pixel Launcher" in it, it seams conflicts with Lineage Stock Launcher, and it will give you black screen.

For Lineage 19.1 ONLY!!!
For sure the better one seams to be the one that Lineage recomends you, that you can find it right here in Google Apps | LineageOS Wiki

CHANGELOG 15-10-2022:
• October 5, 2022 Security Patch.
• Whatsapp audio call issues now gone.
• No more "Internal Error" message.

BUGS:
• VoLTE (Will never work on custom roms on LG phones)
• 10 bit video recording (Watching content in 10 bit works, you just cant record video in 10 bit format).
• You tell me!

QUICK FASTBOOT-DRIVER GUIDE INSTALLATION:
How to install:
1. Extract the fastboot-driver.zip.
2. Open device manager
3. Click right on " Android " it should have a yellow warning icon, press on update driver
4. Select browse my computer then press on let me pick from a list of available drivers
5. Press on Have disk and then go to where you have extracted the zip file and select android_winusb.inf
6. Done.

IF YOU FACE SOME FASTBOOT ISSUES DOWNLOAD FIX-FASTBOOT ZIP :
Instructions: Copy it in main directory (usually in C: drive) and run it as administrator, problem solved.

ORANGEFOX GUIDE:
If you have acces to fastboot, download fastboot-driver.zip and fastboot-tools.zip for the tools necessary to boot ofox.
Open the CMD and use the following command to boot ofox:

fastboot boot ofox-metadata.img

If you don't have access to fastboot, enter in 9008 mode, open qfil and load ofox image on boot_a and boot_b then force reboot (hold volume - and power button for 10s), after it reboots it will get you automatly in ofox.

DISCLAIMER FLASHING OFOX IN QFIL WILL LEAD IN YOUR ROM NOT BOOTING AS LG G7 IS AN A/B DEVICE WHICH MEANS IT DOESN'T HAVE A RECOVERY PARTITION, BOOT IMAGE IS MANDATORY FOR YOUR PHONE TO BOOT, FLASHING OFOX USING QFIL ITS ONLY FOR YOU TO BE ABLE TO FLASH A CUSTOM ROM AS IT OVERWRITES THE BOOT IMAGE WITH THE CERTAIN ROM'S ONE.

INSTALLATION

NOTE: It is STRONGLY recommended to fully wipe your device before flashing and please avoid restoring system apps and system data with Titanium Backup (or with any backup/restore app) as this can cause stability issues that are very hard to debug, restoring regular apps is fine.
If you believe you know what you're doing - then fine, go ahead, but please don't complain if you experience any strange behavior.

"ROM Firmware Required: Must be on 30F EM, 30D EMW/EAW/AWM, 30D EMW for N model"

Would it pass safetynet with microg, zygisk etc? I've heard ungoogled experience improved a lot recently

So I Accidently flash ofox to boot a/b with qfil and now my phone won't boot. Now the screen just show

You need to get the boot_a.img and dtbo_a.img from the kdz stock rom a10 file and you can try flashing it in both boot_a and boot_b, dtbo_a and dtbo_b in qfil, this might fix it. ANd edl is still there, you need to try a fill more, and you will do it

I have also faced that issue. in my case, only edl mode was working. I followed the following steps & it worked for me. You should give it a try.

Is there any way to enable VoLte on custom ROMs on LG G7?

 

[DanCS1995]

Is there any way to enable VoLte on custom ROMs on LG G7?

sadly not, even if you just do a crosflash with another stock rom that isnt from your region, you cant use VoLTE, LG's fault

Hi,

I want to put this Lineage 19 rom on my G7. Can you help me please? My G7 is LM-G710EM, bootloader is unlocked. Its running LG's android 10 up to 01/11/2020 (that appears to be my final update possible - though I thought there was one in 2021?? - no available updates showing there now anyway)

1. (very noob question) when we say 'stock' do we mean just 'what came with the phone, and its subsequent updates?' As in, we didn't install any roms or recovery at this point. Is that right? Thats what i have right now. UK phone.

2. My firmware is V30h-EUR-XX, in this thread it says I need: "ROM Firmware Required: Must be on 30F EM, 30D EMW/EAW/AWM, 30D EMW for N model" - So do I need to find and install the 30F EM firmware? Where can I find the files and instructions please? Is it here: https://lg-firmwares.com/lg-lmg710em-firmwares/ ? ...Or is my V30h ok without this as its newer firmware?

**KEY QUESTION**
3. Could someone please outline for me the 'roadmap' for getting my G7 from: LG A10 -- to ---> L19
(Please correct / advise below)

1. use ofox to replace firmware 30H with 30F
2. use ofox to install L19 over existing LG A10

Is that right? ...or are there steps missing? e.g. I need to install x, then do y, ... and then install L19, or something like that?

Very grateful for any help you can give!

I am a noob but I had some success already putting cyanogen / lineage roms on old devices:
amazon kindle fire, my old HTC oneX, Samsung Galaxy Trend, LG G4 ...all still working fine ;-) ...thanks to XDA.


(I might not be able to reply straight away - work hours - but I'll try to get back asap)

Many Thanks,

Hey, you are fine with your 30H firmware, you should have no problems with it.

Anyway, to change firmware you don't use ofox, you use LGUP
the guide you can find on this thread

Cross-Flash Oreo or Pie firmwares for all LG G7, G7+ dual sim Thinq except t-mobile​

Once in ofox you can do from "CLEAN FLASH" steps of this guide

Hi,

Thanks so much for your reply.

I will not try to flash firmware as you think mine will be OK, but I will check out the linked information you gave for my own understanding.

I will use ofox and follow the 'clean flash' guide from here, as you advise.

That's great! Now I have a plan for action

I will try this over the next couple of days.

Many thanks,

Success!!

Thanks for your help, I have L19 running on my G7 now. the install was painless! all seems good and working. I'm just trying it out, but so far, smooth. It is really nice to have something so up to date running on the phone. also so clean and simple, without all the crud the original system had. a huge improvement.

I have some questions,

- After reboot, trebuchet gives me an Android System message: 'There's an internal problem with your device. Contact your manufacturer for details'
...after I dismiss it, I don't see it again. Have you seen this message? It is too cryptic for me to troubleshoot, but it doesnt seem to be causing a problem (as yet....?)

- Android System Trust Security throws up 2 alerts: This build was signed with public keys ; SELinux is not enforcing, your security has been weakened
...I'm guessing these are ok?

- In the Lineage camera app, the wide camera does not function (only main and front present).
I already put Open Camera app on there, which recognises all three cameras, and gave me great results before this on the G7, so I use Open Camera anyway.

- Can anyone recommend a GCam build for this rom? even better if its older and I don't have to root and do the 'buffer fix' stuff.

If anyone could advise, That would be great thank you!

Cheers,
