Just to be safe here. I flashed v29 and its working great and bootloader is still unlocked according to the hidden system menu.

But i dont want to f*** this up so i might just ask:

For TWRP, the version I should use is 3.1.1.1 right? Thats stable enough?

And for root? Magisk V13.3 works?

Many thanks guys!
[G4 Android Development] tmihai20:
[MENTION=1223091]nortish[/MENTION]: use Magisk 14 (stable). For TWRP use the latest beta from [MENTION=5545101]steadfasterX[/MENTION] https://xdaforums.com/devdb/project/?id=16696#downloads. Also make a backup of EFS as he posted HERE. You can skip data so that the backup is not 32 GB large.
[G4 Android Development] nortish:
Super, cheers mate!
[G4 Android Development] nortish:
Another one for you guys. My phone doesnt seem to be able to boot into download mode. Anyone else experience this? Unlocked H815. No custom recovery or anything yet.
[G4 Android Development] kessaras:
unplug.

turn it off.

remove battery

plug in

hold vol down or up i dont remember

and plug battery in.

download mode cant go away.
[G4 Android Development] nortish:
Maybe. But this is all I get and then it boots up as usual. Tried entering dl mode via ADB also but with the same result.
[G4 Android Development] kessaras:
Download mode via adb ????

....

Download mode can only be accessed us described above. If you can't then forget it don't go into download mode.
[G4 Android Development] nortish:
Don't kill the messager, just found a ADB reboot download in FWUL and gave it a shot. No luck so nevermind.

The reason I'm trying to go into download mode is because i want to do DLM backup before installing twrp and Magisk. Seems to be a recommendation atm.
[G4 Android Development] kessaras:
Hmmm fwul can do that ?

I didn't know that way. Ask in TWRP thread please. Steadfasterx knows more since he made it.
[G4 Android Development] steadfasterX:
The following works 100% - at least as long system, modem and laf are not corrupt:

unplug USB

turn it off

remove battery

plug in USB cable and WAIT until you see a battery symbol with a ? in it!!

hold vol up and keep it pressed

plug battery in while keeping vol up pressed

Wait at least 20 sec or until you see the download mode before releasing vol up button.
[G4 Android Development] nortish:
Yep it worked after a few tries. It turned out my buttons where a bit rocked which made the power button getting pushed at the same time, lol!

But still having problems with the extract-partitions.py command. I'm trying to make the backup to a folder in my /home/android folder but it just times out.
[G4 Android Development] kessaras:
:D

but you still haven't asked in the proper thread. steadfasterX has to track you down in G4 community to solve your problems :D

just go to his thread for fwul and tell him ! makes your life and his life easier, lol
[G4 Android Development] steadfasterX:
That's not related to the OP. Ask your questions in the proper threads. It seems you're referring to DLM backup so ask there as this thread has nothing to do with your question...
[G4 Android Development] nortish:
Sorry. Just saw that it was you who where quoting me and figured it was in that thread. Children running around and screaming in my ears whole morning so the brain is a bit mushy.

I can't use Google Camera with this ROM. Always when I select Photo Sphere or Panorama, the camera app crashes with error "Can't connect to camera". I tried Google Camera 3.2, 4.0 and MGC modded 4.4, but they all show the same problem. Do you have the same issue? Any idea how to fix that?
[G4 Android Development] kessaras:
Ofc. Google camera only works on AOSP and LOS based roms. Mostly AOSP.
[G4 Android Development] hannesausmwald:
I've managed to install this ROM including relock the bootloader

Anything seems to work so far. Sad that LG is not able to launch this nougat Rom OTA for all users. Thanks to all for sharing this rom

[G4 Android Development] lapist:
Google Camera also works on stock Android 6 - just the older version 3.2 of it. At least Photo Sphere works there, while the same 3.2 version doesn't work on this 7.0 with Photo Sphere / Panorama...
[G4 Android Development] kessaras:
What does sdk 23 has to do with sdk 24?
[G4 Android Development] lapist:
I don't know, but I would like to get Google Camera on this ROM working (so far I am satisfied with this ROM so don't want to switch to LOS/AOSP). If that is not possible, I may need to find some other camera with 360° / photo sphere functionality - I want it just for this :)
[G4 Android Development] danpan11:
Guys, quick question, I have H815AR, in my experience I should be able to flash any H815 rom, but the thing is that I was following the Bootloader Unlock procedure from LG with no success since it says that this model is not unlockable.

Is there any way I can flash this rom without using TWRP, no KDZ right?

h818p update problem

When I update h818p to f500k I lost the signal for both sims (emergency calls only)

And I come back to android 6.. But Ihave same problem

Please help:crying:
[G4 Android Development] kessaras:
1) have you done this before again ?

2) h818 with MM kdz had signal ?

3) did you format and restore kdz or only push dirty (download only) , install kdz ?

**As i've never done these kinds of experiments i'm unsure if personally i can help. Creating a thread in help section and waiting for a h818 user would be better.

[MENTION=5545101]steadfasterX[/MENTION] also has done these kinds of experiments on his LG. As a matter of fact the only thing he hasn't done yet is to transform it into an iphone instead of simply changing variants lol.

<Make sure you use the latest twrp beta. It may lag or look like its frozen since its not fully operational yet, but the rom flashing goes on normally. If it freezes wait for it to finish installation before you remove the battery to reboot.>

Please retry until you do or redownload rom and retry. Those are automatically generated , the signature is not something i control manually.

And dont quote the OP ! Edit it and remove this huge quote. You can also use @ and my name (@kessaras) to talk to me.

Its in XDA rules. Also hit that thanks button when you like something or something has helped you.

Follow those rules for the god sake , everyone here in this phone is so ignorant. no wonder the one dev after the other abandon it.

What are the security updates on V29a?

Having some bitcoins for common use on my phone I'd like to patch blueborne and other vulnerabilities
[G4 Android Development] Cristobal88:
Security Patch Level is 2017-07-01 with Blueborne present as well as KRACK ;)

I guess LOS to be the ROM of choice when it comes to security updates… the sole reason I'm sticking with stock is LG's camera app.
[G4 Android Development] kessaras:
your knowledge part is outdated.

you need to read more often. thats history.
[G4 Android Development] Cristobal88:
I explicitly referred to the app, not to the camera/picture quality in general.

You need to read more carefully :p.
[G4 Android Development] thewild:
Actually, he mentioned the APP, not the picture quality.

So he's right, he won't have LG's camera app on LOS.
[G4 Android Development] kessaras:
Lol right!
[G4 Android Development] se1988:
Love the rom. Might even stick with it. Just wanted to ask if anyone have had any ticking sound during calls? Not saying it's a rom issue, it might be network related, but I've never had that before this rom.
[G4 Android Development] harysviewty:
Yeah I noticed it too. But voice recording is fine
[G4 Android Development] magiQx:
first of all BIG THANK YOU!

i do have some issues to report. (tried the search function)

previously had the imperium ROM 6.0 MM. Did a clean install as per instructions.

now when booting i see some error message that the boot status cant be confirmed (or something like that)

cant find a way to make double tap to wake working (bothers me the most)

home button does not get me out of apps (fixed after restarting)

the apps list button does not react (fixed after restarting)

For now thats it. will get back with updates.

Cheers!
[G4 Android Development] attom93:
Not sure but it might be related to wifi. When I was on MM and had wifi turned on and was recording video, the ticking sound was continous. If you had wifi off, then I dont know :) Try calling someone with wifi off
[G4 Android Development] se1988:
You know, you are right! I started a call, it was ticking. Disabled wifi mid-call and the ticking was gone. I don't know how I feel about this

EDIT: Did a little more investigation and found that the ticking in calls are not the same as in video recordings.

I tried video recording, and found that wifi didnt affect the ticking at all. However, the focus did. When the focus changes, the ticking starts. Every time. I mounted the phone on a camera and fixed the focus before recording, and it didnt change focus at all. Guess what: no ticking.

EDIT2: I guess its the focus, as it is moving parts. Its also only in the left channel. I guess its the secondary mic that picks up the sound from the AF. So its a hardware problem. Anyone know if its possible to disable secondary mic on video in the stock photo app?
[G4 Android Development] attom93:
In the app maybe no, but with the v10 camera ported to G4. It has manual video control and you can adjust the sound directivity.
[G4 Android Development] magiQx:
Edit: the battery drain is huge compared to imperium ROM MM. Does anyone have an idea about the screen tap to wake?
[G4 Android Development] cineq:
Your lcd/touch needs replacement. I got the same issue and it's gone with new screen.

Wysłane z mojego Nexus 7 przy użyciu Tapatalka
[G4 Android Development] se1988:
Can you mute left channel completely? Will that make the ticking go away?
[G4 Android Development] magiQx:
Thanks for the suggestion. I did reinstall the OS. Wiped everything again and now it seems to work. The battery drain remains as issue. I hope it is also fixed now.
[G4 Android Development] Caffo74:
It is good to be on Nougat, I tried this for a few weeks, then I switched to H-Rom which is based on this stock G4 Nougat, H-Rom is alot lighter and for me overall better on battery life,

On offense to the OP and great work,

Thank you.

Everyone knows that this is not your rom, so there's no need to point that out "a million times". People just wanna give you credit for making it easily available. Why not just let them, and answer with a simple "thanks"? Just saying.
[G4 Android Development] kessaras:
because if i simply say thanks and dont remind them all the circumstances, tomorrow they will ask mods and report battery and report bugs, and such crap.

They better call LG and complain :p

(and if they ever see an OTA , ill do a change race surgury haha)
[G4 Android Development] thewild:
FYI, I don't have this problem, so it might be hardware related. Or some combo of hardware / software, but at least it's not present on all installations of this ROM.
[G4 Android Development] Caffo74:
Wow how rude, chill dude, I KNOW IT'S NOT YOUR ROM! and I appreciate you bringing it to us all that want Nougat on our G4's as LG didn't provide a kdz, you want to be thankful that you are getting thanked for your work [emoji57]

[G4 Android Development] harysviewty:
Maybe we need newer v10 Nougat port???
[G4 Android Development] attom93:
I don't think it is necessary, g6 rom port camera has all the ability that v10 has. And much more :)
[G4 Android Development] Darts_be:
This is "exactly" my concern!

Thank you for confirming this.

Is the Los camera app that bad compared to the wonderful LG stock?
[G4 Android Development] thewild:
I believe most LOS users use Google Camera rather than LOS (because of video capture being broken in LOS app mainly).

Picture quality is as good as stock, but you won't have any of the manual controls that can be found on LG's camera.
[G4 Android Development] kessaras:
Really ? and i thought that my snapdragon camera app coming from aospa has more manual control..................

[G4 Android Development] kessaras:
Flash the boot in bootloader. I don't know what you did wrong I'm no magician

just do it. go into bootloader and flash the boot.img of the kernel you want there, as boot.

about recovery i got no idea what you did

EDIT: [MENTION=8281409]czarnasm[/MENTION] , you didn't read the op. This is not a rom, this is full nougat os alternative to kdz. now you r on stock recovery after flashing this.

hardware combo does exactly what it sais. if you want twrp again flash it in recovery.

Alternative stock rom that doesnt flash the recovery , is freedom rom.
[G4 Android Development] czarnasm:
how can i go into bootloader?

I only did wipe: cache/dalvik, cache, internal storage and data to have full fresh rom.
[G4 Android Development] czarnasm:
I tried with ADB but without usb debugging it is just not working, I tried to go into recovery by pressing buttons, but when i choose the factory reset phone is just saying "Erasing" and the phone is booting.

Last rom I had was h-rom Nougat based.

[G4 Android Development] dropbear2:
Lineage OS has two version: Official old MM bootloader and Unofficial new Nougat v29a bootloader.

Download Lineage Os unofficial on sdcard.

Download Gapps on sdcard

Go to TWRP, then wipe:

Tap on the Wipe Option

Tap on the Advanced Wipe Option

Make Sure the Following Partitions are Checked

Dalvik Cache, System, Data and Cache

Install LineageOS + gapps.

Reboot.

What are the benefits of v29a Lineage OS over stock v29a? I didn't use lineage yet...
[G4 Android Development] se1988:
The dev of LineageOS v29a said not to use it, it's unstable.
[G4 Android Development] eriuzz:
That new version is compatible with the h811?
[G4 Android Development] kessaras:
None.

Now both are on equal quality. Choose and use the one you like.

He said it because he had to warn the people.

He doesn't develop g4 anymore so he won't fix the one or two bugs there. It's usable and kicking ass, it just has some issues. But which rom doesn't have issues

No. Title sais everything. It's the h815 nougat stock full os alternative to kdz.

If you know how to edit the system and add h811 build.prop and use a bootable h811 kernel, then it's usable. But not recommended. You will lose VoLTE and several other things.
[G4 Android Development] thewild:
Try both and keep the one you like.

It is really a matter of taste. LOS misses some features that might be deal-breakers for some people (NFC, DRM), but if you don't use those it's excellent.

Stock Nougat is excellent too, way better than the previous stock ROMs imho, and you have this so perfect Camera App.

[G4 Android Development] casabato:
Hello. I flashed Nougat with this procedure but I have some problems I would like to expose to have some suggestions.

My G4 H815 has MM v20L, it is unlocked from the first month of use. The smartphoe is rooted and has TWRP 3.1.1.

I downloaded the "H815 Nougat Stock v29A" from the front page links.

I followed the directions, in the first post:

Installation procedure:

This is a Full OS Upgrade for all of us coming from MM.

>> Clean Flash << when coming from MM or from Lineage | AOSP based roms!

- Reboot to TWRP OK

- Advance Wipe -> / data, dalvik-cache, / cache OK

- Install Nougat OK

- Reboot. OK

But when I rebooted the phone, reconfigured, setted up, etc, I can no longer install the TWRP and therefore I can not root it.

When I connect the phone to the PC, ADB does not detect it.

Debugging usb in developer options is inexplicably blocked (the option appears in "gray" and I do not have the option to enable it).

As a result, I can not flash TWRP recovery with ADB because the phone is not "seen".

I tried and reinstall the drivers for LGE MTP without getting positive results.

Did anyone have the same problems?

Thank you
