1. LG devices with a removable battery doesn't support reset by power button, regardless of what OS you are on.

2. What the hell do you mean "Upload Nugat Stock ROM Full"?

3. In Developer Options (tap Build Number 7 times), enable the Terminal app, then launch the Terminal app, and type in "reboot recovery", or if LineageOS has Advanced Reboot, enable that, hold the power button down for power button menu, choose "Advanced (Reboot)" and then "Recovery". Failing that, just switch off your cellphone, then hold down the Volume Down and Power buttons until the LG logo starts to pop up, then let go of said volume button for a split-second, then repress the volume down button while still holding the Power button. If done right, which can be hard, you'll be asked to reset the device - choose yes, and then confirm that, and it will take you to TWRP.

4. Please flash the Marshmallow modem and bootloader stack if your device is permitted to do so.

Hello, thank you very much for your reply to the forum now. This Smartphone has a loaded operating system Android 9.0 Pie LineageOS 1twrp.

I am asking you once again, very sincerely asking for your support, what I should do right now for me to get a good recovery twrp

It seems that at the moment the smartphone does not have a Recovery twrp partition because it probably could have been this partition neatly cleaned up when updating Android

from Android version nougat 7.0 to Android 9.0 Pie LineageOconsole.

I am asking you with a very heartfelt request for help, I have access to the Windows powershell console.

please help me with the command combinations for powershell in Windows 10.

how to enter fastboot boot twrp - with the exact name and spacing, then the power shell console in Windows 10 suits me that there is no such file or direconsole.

Take a look exactly as it is described in my previous post. What is the answer in the Windows powershell conconsole.

I think I have all the required drivers installed for correct Communication of the smartphone with a Windows 10 computer from the CMD console Sorry not CMD only Power Shell because here is the top ten in Windows 10 is now powershell console.he.

how my smartphone runs LG G4 h815 it shows me the information about unlocking the bootloader and I do not know if this information comes from LG or from whom but I write there that I could commit corruption he he he.

this message that I will try to imitate a screenshot so that you can check exactly what it means how you can remove this message quite that the smartphone did not communicate that something is happening because it is annoying for longer the device turns on.

Does Miracast work for you guys? It's simple doesnt find anything,i tested on 2 different smart tvs...Can i make a log of this since it doesnt tell me that something went wrong during the search of a display?thank you in advance and sorry for my english..

Hi !

I have a problem, I explained it on another topic https://xdaforums.com/g4/help/twrp-problem-fastboot-boot-unknown-t3935914

But I don't really know if I should have done it, sorry if you consider it as a "double post".

My "fastboot flash recovery (file)" command works but the "fastboot boot (file)" command doesn't, it says "Booting FAILED (remote: 'unknown command')".

Do you know why ?
[G4 Android Development] polfrank:
I will tell you exactly what I did:

Because I didn't know where the cast setting were, I wrote it on the search in the settings. Then I press the option that comes and then select the 3 dots on the right. There was something like "activate wifi screen sharing " or something and it worked! I can reproduce it now with LOS16 and Chromecast 2nd gen.

This command (fastboot boot) is disabled on v29a. It only works on Marshmallow and earlier on the g4. You should first install the recovery by using "fastboot flash recovery recovery.img" (or whatever you have named the file) and then boot to recovery.
[G4 Android Development] horvalos:

great thx for confirmation!
[G4 Android Development] steadfasterX:
due to a bug in all current LOS (PIE / 16.0 only) builds for the LG G4 the OTA link needs to be changed manually:

adb root
adb shell setprop lineage.updater.uri https://sfxota.binbash.rocks:8010/lineage/16.0/api/v1/{device}/{type}/{incr}

with magisk:

adb shell
su
setprop lineage.updater.uri https://sfxota.binbash.rocks:8010/lineage/16.0/api/v1/{device}/{type}/{incr}

NOTE: needs to be done again after a reboot.

next build will contain a fix for that ofc.

Anybody know if wifi calling works with the H811 version of this phone using this ROM and the T-Mobile network in the US? I've been using my H811 with an AT&T SIM for the last few years, but VoLTE was never possible nor wifi calling. So I have swapped in a T-Mobile SIM, and yeah, VoLTE was provisioned immediately. But I registered for wifi calling, too, and while they said it might take an hour to get enabled, it has already been several hours with no success. I'll continue waiting, but in the mean time, I am simply wondering if it is possible at all.

If you are not the US nor do you use T-Mobile, I'd still be interested in hearing if you have been able to enable wifi calling with your H811, whatever your circumstances happen to be.

And thank you, @steadfasterX, for your continuing efforts to keep this phone alive!!!
[G4 Android Development] steadfasterX:
VoLTE & WiFI calling does not work on any custom ROM. I mean it is possible for some devices out there but it requires a LOT of trial & error and also usually requires to code stuff around it (shims). this is nothing which will ever be possible for this device as I do not have the time for that. If you really require it your best chance is STOCK.
[G4 Android Development] verbage:
Ok, thanks for this clarification. I was basing this all on what I saw under the hidden menu you get to with *#*#4636#*#*. Under the AT&T SIM, the "VoLTE provisioned" toggle was off and gray/inaccessible. But under the T-Mobile SIM, the same option was enabled and turned on.

To figure out if VoLTE was actually being used with the T-Mobile SIM, I downloaded the Network Signal Info app, and made a call. Unfortunately, the voice network type was listed as UMTS * 384 kbps * 3G. So yeah, even though it is theoretically provisioned and toggled on, looks like it is not being used.

My G4s may be coming to the end of their usable life here in the US in the next few months as many service providers are taking down their 3G service to reuse that spectrum for newer 5G service. Sad to think this is the case with seemingly perfectly usable phones...
[G4 Android Development] steadfasterX:
VoLTE and WiFi calling are like VPN tunnels to your provider. there is MUCH more needed then just this toggle which can be even enabled by modding the build.prop but it won't work without adding proper blobs for that, the correct configuration files + ofc might shim'ing the blobs as they are not working just by copying them over. you can believe me when I say its not that easy and yes I tried to make it work somewhen in the past ;)
[G4 Android Development] verbage:
I absolutely do not doubt you--your efforts are legion! I might be able to get along a few more months--maybe more--with this T-Mobile SIM as I do not get the same incompatible phone message I get with the AT&T one, but in the long run, yeah, the days for my G4s seem to be numbered. Thanks again for all your efforts through the years--they commuted the death sentences that my G4s would have received long ago!!!

I successfully unlocked the bootloader on the Brazil H815P variant, everything is fine so far, except this:

I installed the lineage-16.0-20211122-UNOFFICIAL-h815_usu.zip, with Gapps, so far the only problem I've had is that sometimes, in random moments, the system simply crashes, and the only way to get back is to remove the battery and calling again, I don't know what it is, has anyone else been through this? is there a solution?

Edit: I have reinstalled several times to test and try to understand what could be causing two problems I encountered, the first is a total system freeze, and the second is an absurd overheating for no apparent reason or use.

I reached the following conclusion: On my G4, Brazil version, H815P, these two problems are caused by cores 5 and 6 of the processor. Why did I say that? Well, from the various reinstallations I've done, the times I: SELinux in Permissive, Kernel Audiutor: Disabled cores 5 and 6 of the processor, with powersave governor, and the maximum clock at minimum, and in temperature, it just didn't freeze anymore , and the overheating greatly decreased

That means LOS and /e/ OS will get a10 and ofc all ROM @aoleary build too. A10 for the g4 is a project where you can see how important teamwork and patience and being steadfast(!) ;) is. We all together made it possible that we will see a10 for this device anytime soon.

Question. I noticed that while at the home screen my wallpaper gets rounded in the corners, basically cutting off parts of the wallpaper. Thought maybe I screwed something up while tinkering with it. So, I wiped everything, completely reflashed and it still persists. Is this an intended feature or a bug? In the pictures, you can see that if I take a screenshot it show normal 90° edges but in the photo, they are rounded, clearly visible on the lefthand upper corner.
[G4 Android Development] juanpenia:
Hi, this is kind of a repost because I asked this around 2 years ago. I’d like to know if I’ll be able to install this rom and if I’ll have a limitation. My phone model is country specific (H815AR) so I’d like to know if it’s compatible with this rom and if I need to UsU the device and stuff. Also I had this weird software version problem which I explained in my comment which I’ll post the link below and I'd like to know if it will affect anything.

https://xdaforums.com/t/rom-unoffic...91-vs986-lineageos-16-0.3929082/post-80563803
[G4 Android Development] steadfasterX:
No idea tbh..

if your model can be unlocked officially then you don't need UsU. But afaik LG closes unlock possibility soon or has it already. In that case or if the model isn't international you need UsU. As you can see my builds are UsU and official compatible. So that part is no issue.

Limitations ? Like all custom ROMs you will have some. E.g. no VoLTE/VoWIFI , no fm radio, camera quality is good but not 100% as with stock, ... there's more but ig these are the important ones.
[G4 Android Development] rundumdieuhr:
I think this is Android 9 standard behaviour and presumably intended CM feature. I have seen rounded edges for long with Android 9. I believe they got trendy at one point in time (particularly observable on new phones), so that seems to have been replicated in stock Android or CM.
[G4 Android Development] girdap:
I have used december update till launched and I can say it's very stable and everything works fine. It's just like original rom. Btw developer returns to opengl instead of skiagl, I think that's a better choice.
[G4 Android Development] doomanix:
Hey steadfasterX, I'm back running my G4 as my A40 died on me. It's funny that Samsung can't even manufacture a decent budget phone by my LG G4 still boots after 6 years.

That being said, I've had a problem with my G4 continuously shutting down when the screen is off.

It happens every time with every type of rom (stock, Lineage, AEX) rooted or not and only when the device sleeps (using caffeine the phone will run till the battery dies) and when charging it doesn't exhibit the issue.

I've tried multiple things to correct it (reflash modem, replace battery..ect) and it's the reason I left this phone behind. Going back to it now -- knowing A10 is around the corner it's something that I hope you might be able to diagnose.

Pstore hasn't been storing the logs, as it seems they must be wiped when it shuts down, and the phone doesn't exhibit the same issue when plugged in so logging to a PC doesn't work.

I've used logCat Extreme to record the issue as I can capture on device when it hits, I hope they will be sufficient.
[G4 Android Development] steadfasterX:
This sounds like a hardware issue not software.. Does it happen also when just laying around on the desk or when moving around only?

In any case my guess is an issue with maybe the battery connectors or the battery itself (how old is it?) .

The logcat seems to be cut . This plus the fact that no pstore logs are there means the power has been lost completely which all together points to an issue with the battery or its connection. Imho.
[G4 Android Development] doomanix:
I'll take a look into the hardware then. It doesn't seem to happen at all when the phone is running; being lying on a desk (with caffeine to keep the phone alive) or when walking with the phone.

I have three batteries that I've used and all seem to exhibit the same issue.

Might be a ILAOP issue then; just strange the phone is able to function normally -> to sleep before crashing. Do you know of a better solution I could use to capture the logs in this situation? Either way I'll open the phone up and see what I find. :)
[G4 Android Development] steadfasterX:
Nah don't believe that's the ilapo. The ilapo acts regardless of power plugged in or not. Its more likely a circuit failing or so. Don't know if you can fix that but doesn't hurt to try ;)

Updated to this ROM couple of days ago from stock marshmallow.

Really impressed how well it performs.

Better battery than stock Android 6.

Only thing I'm failing is saving photos to SDCARD, only to internal memory.

No option available, I'm on google cam stock and then updated.

Not a major issue.

Hi steadfasterX my NFC is working ok (tested with my Sony headpones registering via NFC and also reading some NFC cards), the problem is that when trying to pay at store via NFC phone does nothing. Nothing triggers. I have got a logcat

https://pastebin.com/fGERByXC

12:03:35 start NFC

12:04:02 approached phone to NFC pay terminal

Reading the log can be seen as NFC protocol seems to start requesting a read messsage and got a write message... but this goes on and on in a loop.

I have tried with banking APP and with google pay with same result. Nothing happens.

Yes I have MAGISK installed... if you see something wrong on the log... good! if not... no complaints.

Thanx.

2. flash the 20p UsU bootloader zip (https://leech.binbash.rocks:8008/stock/LG/h815/20p/ --> h815_UsU_20p_bootloader_20p_modem_TWRP-flashable.zip ensure downloading the UsU one then!) by TWRP/SHRP

[G4 Android Development] 1captainjacknotsparrow1:
So I switched from LineageOS 18 to 16, because of it being not secure by SELinux being deactivated and not even mentioned in the start post. Still would be the right thing to do to add that info in the start post of your LineageOS 18 rom for the G4.

But now I have some questions for your LineagesOS-16-rom:

1) No new security updates released since January? Or you just didn't have enough time to do it?

2) How to install any updates correctly? Just flash the zip in TWRP and my old system settings etc. stay the same?

thanks in advance
[G4 Android Development] steadfasterX:
1) as mentioned in the 18.1 thread IT IS MENTIONED in the OP. You should read the known issues but if you don't sorry.

2) security patches coming from LOS. LOS does not support 16 anymore so no sec patches so no new builds.

3) a full clean flash is required which is described in the FAQ. Ofc you can't switch between ROMs and keep settings and apps. That's not possible. You can only backup & restore and even then some apps can fail .
[G4 Android Development] aoleary:
1. I need to work on the getting A11 enforcing. It is a bit particular though, compared to Pie.

2. LineageOS used to maintain security patches for much longer before.. A pity, but we all have real lives outside the custom ROM scene..

3. There used to be a great app for that, but he stopped before Nougat..

[G4 Android Development] steadfasterX:
video should just work on pie like it does on all others. could you try with selinux set to permissive please? if that works gen a new log like that: reboot, do not start cam, set permissive, start video, grab log. thanks

EDIT: oh and I never said this is not supported anymore - just that likely less or no builds will happen anymore due to the lack of security patches. but when there is an issue fixed affecting pie it will be backported here as well

Glad to hear you're still supporting 16.0. The 'relevant' security patches are still being uploaded by some LineageOS Gerrit members so I am keeping the rom up-to-date for my H812 UsU device. In the web site, in the search bar at the top right, you can enter, for example, P_asb_2022-08 and find if the patches have been uploaded. The only difference is that they are not being 'Officially' merged in now but the topic can be repopicked with no problem and the end result is the same.

Thanks again.
