i don't know mate , i have never digged in bootloaders that deep. [MENTION=5545101]steadfasterX[/MENTION] will know something but will have to wait for monday.

Did you flash all possible partitions that flashfire can select ? its a dangerous procedure, it shouldn't be tested by anyone that doesn't know what to do.

Only a few tried it and succeeded it but they didn't make a guide somewhere. You should ask first and wait patiently for someone who already did it to post a guide.

For the future:

if stead helps you and restore it, please wait patiently as he also works on something really good for all the locked variants. Soon you will know what.
[G4 Android Development] CygnusBlack:
Thanks. I though that following the instructions of Carlos, the other 815p user, would work without issues...but no.

About flashfire, yes, I left it untouched as partitions go (I've followed some guide on the internet).

Anyway, I'll flash a stock MM kdz and let this one rest.
[G4 Android Development] popy2006:
Yeah I have that feeling. Running some Tasker scripts and the result is false (= offline) sometimes but wifi is on!

The setting is set to yes (keep wifi on during standby)

Any hints?

Or must the setting at too off(wrong German translation) ?

How are your power saving settings ? I fixed this wifi problem by disabling "per app profiles" in battery settings.

Don't expect too much though, it worked for me but others tried without success.
[G4 Android Development] steadfasterX:
Something...? Lol ;) I EAT the bootloader and spied it out to create a cake out of it so..then repeating this with different models so... Something.. Is not the right word ;)

[MENTION=5461026]kessaras[/MENTION] your download here has not the 4cores fix or the raw resources boot message fix correct? Completely stock as stated I guess. Just want to be sure.

If there is anything just a bit different then pure stock it would fail for locked phones.

What exactly do you had flashed? Which partitions?

That error means you have a locked device (which is expected as you have no international) and it seems you haven't flashed all required partitions. Likely not the complete bootloader and/or modified boot image in your case.

[G4 Android Development] kessaras:
[MENTION=5545101]steadfasterX[/MENTION] bootloader is 100% clean and pure here. i'm not touching anything [even if they request it many times :p]

one or two did it right and upgraded to nougat with flashfire. One of them should at least make a small guide for the less experienced users.

Anyway.

[{Something} because i want to keep it a secret until its ready. I want it to make a big impression]

Just flash the V20 KDZ using the LG tools?

Kessaras has in his Downloadsection v20p modem and bootloader. Just flash it in twrp and than restore your mm twrp backup or install a stock based custom zip like freedom or imperium or los if you want.

You can also flash a kdz via lgup, butnotice your custom recovery will be replaced with the stock one. But bootloader is still unlocked. So flash twrp via adb is really easy like in the instructions written.

Just updated my G4 H815 Eur to Nougat fro H81520g using your Zip, thank you. All apps re-installed and everything working as it should.

Will the fast boot method to install TWRP work with this OS. The reason I am asking is because I have a V10 H901 (T-Mobile) which updated OTA to Nougat and it will not allow TWRP installation with fast boot.
[G4 Android Development] Hostilian:
Last question before I give this a go..

There were some reports of screen burn, from the Nougat OTA update in Poland (some users sent their phone back for repair/replacement).

Is this a problem with this version or does it depend on hardware quirks..

Wondering if LG might be fixing this - maybe causing the delay in an OTA update for the rest of us..
[G4 Android Development] kessaras:
You can.

fastboot flash recovery <recovery.img>

latest beta 14 or newer

mine is plugged in 24h/7d testing codes, merging, testing, deleting and testing and is fine.
[G4 Android Development] Daniel_Viani:
Thank you! I was using a different version of v20 hoping it was different!
[G4 Android Development] popy2006:
It's a hardware issue many h815 faces! Mine too but lg/amazon replaced it under warranty.

Just Google and you will see that's a common g4 hw issue.

Hi

Trying to install TWRP but cannot get into bootloader. ADB devices shows device ok but when i try to reboot bootloader i just get "waiting for device". I have latest LG drivers installed and my PC sees the G4 ok. Any ideas, anyone.
[G4 Android Development] stefan.kurz:
You have to do this from Homescreen. Although you need to confirm that the Phone boots in Bootloader.
[G4 Android Development] kessaras:
thats pc related, i don't know whats going on there.

use FWUL of [MENTION=5545101]steadfasterX[/MENTION] if you can't connect and sudo fastboot flash the recovery

Hi, can someone please advise me where I'm going wrong.

I've unlocked my BL and download the twrp file, renamed to TWRP.img which I've placed in the adb folder.

I can boot my phone into fastboot but whenever I type "fastboot boot TWRP.img" I just get the error......

"cannot load 'TWRP.img': No such file or directory"

I've tried renaming and also downloading again but it's always the same
[G4 Android Development] Hostilian:
Think you need to have the TWRP file on your PC AND your G4...
[G4 Android Development] Stransky:
Hi

Yes did all that. Even tried on another PC but still get "waiting for device" below command.

Edit: just tried using Laptop and success. Now have TWRP and Rooted H815 on Nougat. Cannot understand why this will not work on my H901 V10.
[G4 Android Development] rocky184:
I have got the file on both the phone and PC but still not working.
[G4 Android Development] Hostilian:
As a sanity check, try renaming both files to g4-twrp.img on both your phone and PC.. All in lower case..
[G4 Android Development] rocky184:
Thanks - just tried that but still not worked.
[G4 Android Development] Stransky:
You need to type "fastboot flash recovery TWRP.img"
[G4 Android Development] mughal23:
Open the command prompt within the adb in which you've placed the recovery.

My pc dont recognize my phone

I've intalled the v29 rom. Now I want to have twrp again, but my pc dont recognize it. I've have on windows ( with amd without the drivers), on linux, with the phone booted and also with the down volume and pluging the phone. Any ideas, plz
[G4 Android Development] kessaras:
this is not windows or linux debugging forum, you should ask there, or Stead in FWUL thread. They should know better.

The only thing i can say is that it happens many times to many pc and you need to setup udev rules in linux.

Without udev rules in linux you can sudo fastboot to force it do what you want.

Guys, one question. Everything's good with the beta version, but whether we will get the final version of nougat by update directly from the phone update menu or have to flash again when release it? And when is possible to get the final nougat for H815? Thanks!
[G4 Android Development] Engelm:
You should be able to get it through the phone update menu if your BL is locked.

And again, it is possible to get final nougat .... .... ... yes - of course.. when they release it!

[G4 Android Development] xdaboobs:
Hang on let me get this right -- the boot loader is auto locked when installing this rom? Because i loaded it and android pay still doesnt pass safety net.

I had an unlocked bootloader. Then installed this rom from twrp.

So now do i need to re-lock the bootloader, then format data, and then reboot?
[G4 Android Development] eldriSs:
Once you unlocked the bootloader using LG`s instructions from the

official

site, it stays unlocked forever.

Did anyone flash device from CM Nougat 7.1.2 to this the latest beta stock 29A ? I have problem with NFC payment, I'm corious that this issue will be also on Nougat stock.
[G4 Android Development] xdaboobs:
Ah dam that's annoying. Guess i'm doomed never to use android pay on this phone! hahah

Well, i was using lineage OS nightlies since genesix started, but NFC payment never worked even tho android pay passed the safety net. (BTW i found on lineage OS NFC always fails to push data out... however, i found that it can read data from cards - tested this using NFC reader app). But with this "boot loader unlocked forever" problem android pay won't work regardless.

Here's the thing,

I flashed this rom a couple of days ago and wanted to try the V30 port and found that twrp was not installed anymore, so I tried to reinstall with the known fastboot commands without any luck when executing the command astboot boot twrp-lgg4.img i get a downloading 'boot.img' and right after that I get FAILED (remote: unknown command).

flashed back to mm and reinstalled twrp in the exact same way without any issues, reflashed this rom and I am getting the same thing. Oh and I also tried the fastboot flash recovery command but unfortunately no way of installing twrp at the moment. oh and I use the latest version from the team win website 3.1.1.1.

does anyone has an Idea?
[G4 Android Development] stefan.kurz:
Fastboot boot doesn't work on nougat. Replace boot with flash. Fastboot flash twrp.img

And all works well
[G4 Android Development] Robert_1968_:
well I tried your suggestion (thanks by the way) but when I run the command: fastboot flash twrp-lgg4.img I get the unknown partition 'twrp-lgg4.img'

error: cannot determine image filename for 'twrp-lgg4.img'

when I use the fastboot flash recovery twrp-lgg4.img It looks like it is flashing but when trying to boot in recovery I get the green android on his back wit the no command message.
[G4 Android Development] Stransky:
You need to " fastboot flash recovery twrp-lgg4.img" i actually renamed the file to twrp.img and it worked for me.

Flashed it yesterday, all seems fine. I managed to install TWRP and root without fuss, and all it's working. I don't use nfc though. I'm having some random bluetooth audio streaming skips on the long term playing (audiobooks and such), that's the only thing i noticed for now.

Hmm. Maybe then search Google to find somewhere in a community in XDA a compatible .dll mate for your phone.

There is a chance you won't find any compatible because you and maybe one more guy in whole planet has h815p with nougat..............

[G4 Android Development] kessaras:
https://lg-firmwares.com/lg-h815-firmwares/#squelch-taas-tab-content-0-1

sort using file name. LG firmwares are a mess. Each country has its own firmware and not all countries get equal updates.

Latest is 20i if you sort by date , which has latest security patch ( supposed to ), but latest firmware is alphabetically (a,b,c.....p) P

so, 20p is latest MM firmware with the latest modem and bootloader inside. (example used h815 international)
[G4 Android Development] aalvico:
Considering European, is alphabetical order, so P is newer. Other markets or carriers use different letters (less updates) so can't compare.

Consequence of unlocking. Bootloader. Cannot be removed atm. Just forget its there. Has no effect on phone.
[G4 Android Development] kklevi:
Follow this link.

For me it worked. Make sure no TWRP is installed or other custom recovery. (The installation of V29a ROM wipes TWRP so if you didn't reflash it, it shouldn't cause any problems for you.) Make sure your phone is backed up including media as it's gonna wipe everything as a factory reset would also do that.

Proof. By the way you can find it by typing

*#546368#*815#

in the dial pad, --> SVC Menu --> Bootloader Unlock Check Test. (Works if you're on Android 6.0 at least I think. In 5.1 or lower I think it's

*#*#7378423#*#*

if I remember well, and it should work for almost all Android phones, at least running Android version below 6.0. The 815 in the code is because my phone is 815 model - e.g. if you've got H811, then, you type 811 in that place.)

On the screenshot you can see from the UI that my device is running Nougat and my bootloader is locked. No more strange messages at booting for me. :victory:
[G4 Android Development] sas007:
I relocked the boot loader and it went but I only had this notice once on first boot when bootloader was unlocked..others report it disappears after a few boots but don’t know if it is so..
