I do have sound issues. Basically no streaming video works, sounds doesn't work, and music doesn't work. Bluetooth audio streaming was working earlier, not sure if it still is.

I did usu via salt, flashed twrp via fastboot, flashed H812_UsU_baseband_flash_in_twrp.zip, then nandeoid backup.

That left me on MM stock that I was on before.

Then I decided to flash aoscp Oreo, so I flashed G4_29a_N_modem_UsU.zip and then H812_UsU_baseband_flash_in_twrp.zip again and then flashed the rom, then open gapps.

At that point I was on Oreo but no cell service, so I flashed G4_29a_N_modem_UsU.zip and then H812_UsU_baseband_flash_in_twrp.zip again and that gave me cell service.

Then I flashed the latest version of magisk to get root.

Besides having no sound and video everything else seems to be working so far.
[G4 General] nummer:
Ah, but still, sucks that video cant be played on the custom roms, maybe sfX will have to do something about this :(
[G4 General] steadfasterX:
Well regarding the video/sound

Sound is modem partition

Video is modem partition

It's odd that it happens though.. Well the thing is this requires debugging.

When playing sound do this:

adb logcat -d

This may give a lot of output. Use e.g. bpaste.net or gist or attach it if nothing works

As another test:

flash the modem partition of the firmware which you had installed before flashing UsU. then try again. If it fails or hang on boot/crash/bootloop flash the baseband package again

On every step do that logcat command above and paste it
[G4 General] FoxyLove:
I tried an another rom, and I still have the same problem. I flashed the modem and the baseband for my H812. I don't know how to solve that problem
[G4 General] slim902:
I'm out right now for a few hours but when I get home later I will post the outputs.

For the modem I checked the links in the FAQ and there is a Telus modem partition there for the h812. Are the modems carrier specific? I'm with Koodo, which is a Telus brand so Telus sim cards work with Koodo if that matters at all.

I also did a salt backup before I did anything, so if the modem partition is in there I could use that if you think that would be better.

Thanks again.

Theres something i can do in my lg g4 us991 11a? firmware is lollipop 5.1 and i cant update
[G4 General] sdembiske:
By 'update', I suspect you mean by OTA or LG Bridge? You will have to update using LGUP - NEW. You can get firmwares for your device here: https://lg-firmwares.com/lg-us991-firmwares/#tab=firmwares - scroll down to Firmwares. You can check known arb version

beforehand

here: https://xdaforums.com/showpost.php?p=73206763&postcount=3 -

make sure

your arb version is 2 or lower for whatever Marshmallow firmware you upgrade to.

One you have upgraded, do a backup in SALT before proceeding to UsU unlock your device - read thoroughly the OP in this thread, making sure you understand it fully and then proceed exactly as written to unleash (unlock) your device and root etc.
[G4 General] minomx:
hi, can anyone help me or im going to die with a heart attack >> without unlocking my LG G4 H815 ...... T_T

after i do the unlock method :

* Extract <model>_UsU_unlock.zip and copy the aboot_UsU.img, laf_UsU.img and rawres_UsU.img to either:

b) connect your running Android device with your PC, select MTP mode in Android and copy it to the:

- "Internal Storage" and folder "Download" (exactly there!)

* Start SALT

*Open the Advanced Menu

Click the "Unlock G4 (UsU)" button and read carefully the popup. Click Unlock.

and it was successful

i get now the secure boot error and in the SALT i get USU as Yes

but i cant get it how to flash TWRP ??!!! the hard attack getting closer when is see falsh TWRP T_T..

what is that i have missed how to flash the TWRP for god sake .......

by the way i have read the thread 100 times
[G4 General] sdembiske:
You obviously didn't read it as closely as you should have, eh? Refer again to this section in the OP:

OK enough about all this: LETS UNLEASH YOUR DEVICE!,

Starting from this line now

:

If the UsU flashing was successful (SALT will validate the flashing) continue:

Boot your device into fastboot mode (yes UsU has enabled an unlocked fastboot access for you!):

thoroughly through to this line

:

If you do not boot to TWRP after flashing it it will get OVERWRITTEN and you have to do all the steps for flashing TWRP again!
[G4 General] minomx:
the problem is i did that and i didnt boot to TWRP and i didnt get it how to do this If you do not boot to TWRP after flashing it it will get OVERWRITTEN and you have to do all the steps for flashing TWRP again!

:confused::confused::(:(

http://prntscr.com/nrkfim
[G4 General] sdembiske:
The screen shot you provided does not indicate that you have actually flashed TWRP. The fastboot flash recovery <twrp.img name exactly> command has to occur when in fastboot mode in your sdk/adb folder (on your PC, where you've copied the TWRP image to), when you're connected in fastboot mode - it should show when the command has been executed successfully that it has completed the flash.

Addendum

: [MENTION=4910179]minomx[/MENTION]

If you did flash TWRP successfully before, then what you have done is booted back into fastboot mode again, not into recovery mode where TWRP resides. If that is the case, re-read the OP again, paying particular attention to what is written under the section:

Changes in behavior

.
[G4 General] minomx:
ok, sorry for been so dumb to understand where and how to flash the TWRP, you saying ""The fastboot flash recovery <twrp.img name exactly> command has to occur when in fastboot mode in your sdk/adb folder (where you've copied the TWRP image to)"" the whol problem is how to flash TWRP ...

i used the FWUL v3.1 and SALT to unlock the device .. and in the thread and speicaly in this section ""OK enough about all this: LETS UNLEASH YOUR DEVICE!"" nothing on how to F... flash the TWRP.

so how the hell am i going to know where and how to Flash the F... TWRP . when it just says. Flash TWRP (yes you can do that now... because of UsU!): oh nice yes i can but i dont F... know how to. very very SAD FACE. :(:eek::rolleyes:

and thank you sir for the replays :angel: you are very kind :fingers-crossed:

i will die in peace :angel:
[G4 General] ST Dog:
Well the command was given.

fastboot flash recovery <twrp.img>

Spend a few minutes looking for info on fastboot and flashing.

Short version, once the phone is in fastboot mode on the connected PC you execute fastboot commands (similar to adb commands).

At the command prompt you type the command.

Stuff in brackets, <>, are arguments to be replaced with the actual filename.

If not in the current directory, give the full path to the file. That's the path on the PC.
[G4 General] sdembiske:
A certain knowledge is presumed when undertaking flashing custom recoveries, roms etc. You are obviously very new to the game but sometimes it pays to do a little homework/search, either in TWRP or the web in general, first - it can prevent a lot of mistakes being made down the road.

Here is the link to TWRP for the LG G4: [RECOVERY][OFFICIAL][F500,LS991,H81x,US991,VS986][MM,N,O,P] TWRP [2019-04-29]

You'll find all the versions you will need there but for now I would recommend, once you're rooted (here is the Magisk link: https://xdaforums.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445 - adb install the Magisk Manager apk first, then reboot into TWRP and flash the Magisk zip when you've put it on your device's SD card), install the Official TWRP app after you've booted back up and check to see if the version you have matches what is selected for the LG G4. Flash the selected version in the app if it is different from what you've installed, for now.
[G4 General] Sir Daniel III:
Hey you may have missed this in the original post:

In order to flash TWRP you need to be in fastboot mode, but I'm sure you're wondering how to get there. Well...

1. unplug the usb cable from the PC (not from the device)

2. Insert the battery again

3. wait 2 sec

4. press volume DOWN and while keeping it pressed: plug the USB cable to the device

5. keep volume DOWN pressed until you see the fastboot screen

You should see a bunch of little text on the top left side. Now you can properly flash TWRP to your phone with the command "fastboot flash recovery [twrp.img]"

You then power off your device by unplugging the USB and taking out the battery. Then put it back in and boot to TWRP (power + volume down) or else it will get overwritten. Once you've loaded into TWRP, go into reboot, and press reboot recovery. You should be free to do whatever flashing you need now.

"UsU is based on an ARB 2 based aboot (part of the bootloader stack) and so ARB > 2 will hard-hard brick your device if you would flash UsU on it. Hard-Hard brick means no way to recover other then sending for repair."

OK, then. A lot of us have ARB 3. Can we get a USU based on this so we can root, or any other suggestions, like smashing it and getting another rootable phone?

Rootable

I would really like to see a list of rootable phones for 2019, including from LG. I used to have my g4 rooted, and it worked great. Then it boot looped, I sent it for repair, and the Bastards had put 22f ARB3 on it, ruining it. Basically, how can I tell if a phone is rootable without spending hours searching Google?

Haven't seen one.

Most carrier free devices can be, eventually though often not at release and they tend to be released after the carrier versions.

LG list for official unlock is European versions recently.

I found out about UsU yesterday and I'm very interested to give it a go on my old G4 H815L.

After reading the OP I’m a bit confused about the requirement 3.

My phone has the latest 6.0 OS. I did a SALT backup and found the following data:

Firmware (laf)= H81520g

Firmware (system)=LGH815LAT-00-V20g-ISR-XX-NOV-23-2016+0

AntiRollBack=0

a)	Is this firmware good for the process or should I do something?

b)	I wish to go to Pie rom, if I use your linage->pie-> h815 should I do something special in the installation process?

Thanks for giving new life to this phone!
[G4 General] sdembiske:
You should be good to go - just ensure you have a copy of your modem.bin file in your SALT backup as you will need it.

- Read everything carefully in the installation/unleashing process, making sure you understand the process and follow it exactly, careful not to miss any steps.

- When you're at the stage to install TWRP, make sure you are on the correct,latest preview version that matches the rom version you are going to install.

- When you're at the stage to install the custom rom, make sure in TWRP that you have first backed up your current stock rom and backed up/copied any data (videos, photos, etc.) on your SD card to your PC. When installing the new rom, wipe Cache, Dalvik cache, System and importantly,

format

Data > Yes before flashing the rom, then install OpenGapps (arm64), reboot to the bootloader/fastboot screen and flash the Marshmallow (MM) modem.bin file from your SALT backup then boot up the system.

- Once booted up, to root your device, adb install the latest Magisk Manager apk, reboot to TWRP and install the latest Magisk zip.

One consideration, the LineageOS 15.1 rom is still more stable and overall, IMO, smoother at this stage than the 16.0 version that is earlier in its development.

Hello, UsU users and thank you SFX. So far I have UsUed two h815's (cheap phone from China) and they are working very good. This time I bought h810 (again from China) for fun. I connected it to FWUL and found that ARB = 4. Yes, I immediately stop doing UsU for it. I learned from other thread change/modify ARB is impossible. What I am curious is: there is UsU for h810 and about 5 % of users successfully UsU'd their h810, this means (maybe old) h810's ARB was less or equal to 2? If this is the case I will stop searching for unlock bootloader and play with my new h810 with pre-installed ROM.

It depends your h815 is a real, international one or not. If so you can forget about UsU, just visit LGE official site for unlocking officially.

[G4 General] Korin67:
I do not understand what 20f version means, it should be a variant of h815, right? Well, after you successfully UsU'd your phone, what people do is to install TWRP. Read OP and find the right TWRP. What was difficult for me is to set the phone in download mode. If you clear this step, you can install TWRP with fastboot command. Once, you install TWRP, you can install any ROM, gapps, and Magisk if you want. I do not know if you can get android 5 for h815_usu (I have not tried it). Why not go to the newest android 9, Pie? Regarding android Pie for h815_usu, there are three selections as far as I know, LOS16.0, AEX v6.6 and AOSCP. You can try and compare.

What I wrote is very well written in OP. The first thing you need to do is read OP carefully.
