Lg G4 H810 successfully unlocked

[MENTION=5545101]steadfasterX[/MENTION]

successfully unlocked h810 AT&T thanks to you :good:.

I was at stock H81010o (ARB=2) as per SALT and I updated it to h81020n (marshmallow which was also ARB=2) via LGUP. (BTW I think h81021y is ARB=3). did a basic backup of device using SALT version 3.19 ( using FWUL_v2.7_x86_64_8GB and it was run through a bootable usb ----- SALT version was 3.16 so had to update it to 3.19 before using it ---- i was having issues in connecting device to VM therefore had to use bootable usb option-----) and flashed UsU (by storing the UsU files in - "Internal Storage" and folder "Download"), booted the device to fastboot mode and than flashed TWRP (version twrp-3.2.3-0-g4.img ----- it is stable one not the pre released one).

Then booted in booted in TWRP and flashed _UsU_baseband_flash-in-twrp.zip. Rebooted into recovery and made TWRP backup including bootloader and than all went well.

All these above steps were done according to your guide and unlocking was successfull (only change was the use of TWRP stable image. )

Currently running custom lineage 15.1 rom (lineage-15.1-20181003-UNOFFICIAL-h810_usu.zip) with magisk 17.1 and device is performing well; although magisk is unable flash zip modules which is already present in the storage while rom is booted but if install option is selected then module is downloaded and installed accurately. so therefore flashing the modules in TWRP is the option i am currently using since i have modules already present in my storage.

Same is the case of TWRP app not seeing zip files on booted rom so have to flash all the zips by going into recovery.

known issue of Flash light not working is rectified by using "kz Torch - Adjustable torch for LG G4 *ROOT*" apk.

I had tried your cypher os (aoscp_h810_usu-4.2-20180421-unofficial.zip) and flash light is working in it but the default launcher not changing the color to dark mode had made me switch to lineage.

over all everything is working in lineage as it should be but i am having issues when using titanium backup pro. custom lineage rom is not allowing titanium backup pro to make multiple profile widget on home screen. the launcher closes whether its default launcher, pixel launcher (Gapps) or google launcher.

I was wondering if you could guide me regarding this issue that is it because of magisk, or rom not installed correctly or anything else.

Again thanks for giving us this guide to unlock G4.
[G4 General] sdembiske:
The problem is most likely restoring apps/widgets from Titanium backups - known problem with Titanium on custom roms.

Download the app from Playstore and create your widget from there. You can try restoring Data (only) from the Titanium backup but if that fails you will have to recreate the multiple profiles.

Recommend you install the latest

preview

'O' version of TWRP from: https://xdaforums.com/g4/development/recovery-twrp-3-touch-recovery-t3442424.

I don't use the TWRP app for restores, always from TWRP recovery but you can see if the preview version helps with restoring from the TWRP app. If not, post the issue to the noted TWRP thread but search for it first in the thread, to see if has already been addressed.

With respect to Magisk, post the issue to the Magisk Canary Channel: https://xdaforums.com/apps/magisk/dev-magisk-canary-channel-bleeding-edge-t3839337 - install the latest debug version and post the Magisk log in that thread with a description of the issue after you have searched to see if already addressed in the thread.

[MENTION=6302635]sdembiske[/MENTION]

Thanks for your recommendation related to TWRP and Magisk and pointing to me towards the right xda threads.

Although i have chosen to continue with TWRP stable release due to its compatibility of recovery with UsU lineage. The detailed reason for not continuing with latest

preview

'O' version of TWRP is when advance power menu is chosen from developer options of lineage than no reboot to recovery option is shown when power button is pressed which means that preview release is not integrating or being compatible with UsU lineage rom but if stable release of TWRP is flashed than it is compatible and showing the whole reboot to recovery option.

Regarding Titanium Backup Pro the issue was that when a new widget is created of Titanium backup app and if it was chosen for creating multiple data profile of an app which was already restored or even a new app was installed from play store than launcher would crash and no widget would be created or stored.

I wasn't able to find any solution therefore mentioned it here although i know these issues were totally unrelated to UsU G4 unlocking guide.
[G4 General] sdembiske:
I run the the TWRP preview O version on LineageOS 15.1 and have the recovery option on the advanced power menu - perhaps your forgot in that instance to activate it in the Developer settings?

Have you tried Nova or the latest Apex (my personal favourite for customization) launchers to see if the problem replicates there? ... I.E., it could also be launcher related but suspect it is still mostly a Titanium restore issue with respect to using it on custom roms.
[G4 General] us3randroid:
yes i did forgot something in my previous reply :) that instance of advanced power menu was activated in developer option but still boot to recovery option didn't show up at my device when TWRP preview O version was flashed.

will try these new launchers and let u know the outcome. hoping it would resolve titanium issue :)
[G4 General] steadfasterX:
The recovery button in the advanced menu has nothing to do with TWRP stable or preview edition. Its just a setting which reboots to recovery which could also be another recovery.

Lineage does not check if you even have a recovery installed as it's just a command to boot there nothing else!

I use that setting always and its the first thing I enable on every LOS test build I make.

I have LOS 15 as my daily driver and ofc use only preview TWRP builds.

So when it does not show up its not TWRP related.. Factory reset and / or try to reboot once after you enabled the setting
[G4 General] us3randroid:
Thanks [MENTION=5545101]steadfasterX[/MENTION]

Did the same thing earlier. But command didn't show up therefore flashed the stable edition and command was visible than. So did the whole clean installation of os ROM just to be sure and command was still visible. I don't know y it didn't show up when using preview edition but now moving on since my issue was resolved.

[MENTION=6302635]sdembiske[/MENTION] your refer to the launchers helped me resolve titanium backup pro widget issue. Nova is working just the way I wanted it to and widgets are being created without crashing the launcher
[G4 General] roberto888:
[MENTION=5545101]steadfasterX[/MENTION] Been some time, but I'm back. I found my SALT backup folder on my Google Drive. What should I restore from it to try fix my No Cellular issue? Thank you.
[G4 General] mark324:
I normally don't have my phone ringer up or any other notifications, but today i decided to use them, but the ringtones are nowhere to be found, even the sound effects is gone when you turn ringer up, sound effect for tapping, all I can use is the music file added form my music player. I restored my stock rom from twrp it's not there either.Anyone else have this problem.?
[G4 General] steadfasterX:
My memory is like RAM - volatile. oh... I will add that to my sig :p

ok so no idea what your issue was but when you have no cell service you should restore the

correct

modem partition and clear modemst1 and modemst2 -> This will REQUIRE new unlock keys IF your phone is not SIM unlocked (means you need a code to use other cell providers). If you have old ones they may NOT work anymore so you must request new ones - afaik.

So restore:

- modem

- modemst1

- modemst2

- and FORMAT data -> before rebooting to Android!

if that doesn't work do the same again but with a modem partition of the

oldest

Lollipop

(aka v10) version you can find for your model. This may result in a bootloop (which can be fixed by flashing another modem partition version) so be prepared.

If that still doesn't work:

fastboot erase modemst1
fastboot erase modemst2
fastboot format userdata (will wipe ALL your internal storage ofc)

.
[G4 General] roberto888:
I must have flashed the wrong modem at some point, cause I seem to have lost my network unlock, although if I'm not mistaken it supposed to be an unlocked phone by default. When i open the sim unlock menu with 2945#*815# it says that "This phone is permanently locked and can not be unlocked." in all the options. I am having the wrong clue, and should I still proceed with your instructions?
[G4 General] sdembiske:
First thing that I did when I had a similar issue was to flash the MM modem.bin file from my SALT backup (fastboot flash modem modem.bin). If you don't have one, flash the modem.image file from a SALT extraction of your MM kdz. Did the trick in my case.
[G4 General] mark324:
I've flashed modem, still no changes. I'm not sure if the default ringtones are even in the phone anymore, I don't see them in any folders. It's weird cause i made full twrp backup after unlocking with salt and restored and still nothing. Is there like a ringtone manager on g4 other than using music players, cause that's all I can use right now.
[G4 General] sdembiske:
If you don't have the ringtones in Settings > Sound, then it could be more of a rom issue - Did you flash or install something that might have corrupted it or flash a rom that wasn't on the listed custom roms in the Downloads section in the OP or didn't match your GPT compatability?

I would, in your case now, clean flash a rom specifically for your device from the Downloads section. Make sure you are on the latest preview TWRP version for the rom version you select (MM, N or O). Backup your data in TWRP, reboot to recovery and then wipe Cache, Dalvik cache, System and most important,

format

Data, flash the rom, install gapps, reboot to recovery and install your preferred root version. Boot the phone up and see if your Ringtones in Settings > Sound are restored and you have sound from them. If not fastboot flash your MM modem file again and reboot and check again. If all good, restore your Data backup in TWRP. If not, consider going to IRC for steadfasterX's help (see OP).
[G4 General] mark324:
I have installed other ROMs but then went back to this stock one, can't be sure if ringtones and other sound effects worked on those. With my salt backup, are you able to restore the whole phone from there? Or is that just for extracting individual files.im guessing so I couldn't find any restore options. Also I've flashed the modem from salt and still nothing, and there are modem.bin and modem1 and modem2 I think, should I flash those Also. One more thing, when ppl say extract modem from kdz in Salt, is that the same as taking the file out from the salt backup I made.
[G4 General] sdembiske:
Do a

clean

flash

exactly

as I described in my previous post of a custom rom from the Downloads section in the OP, paying particular attention to

format

Data.

Try that first

before restoring any partitions from your SALT backup - for that, defer to steadfasterX on IRC for your particular issue - I believe you only wipe the modem1 and modem2, not restore them. Flashing the modem file from the SALT extraction of your original MM kdz except for the command: fastboot flash modem modem.image
[G4 General] mark324:
Sounds are fine on custom ROMS, just the stock rom I'm missing sound files and folders, I confirmed this by comparing the system.bin in my salt back up and my system images in TWRP backup, I don't know how this happened but the sound folders were missing from "/system/media/audio in the Twrp backups. Would it hurt if I restore the backup from my twrp, then flash the system.bin from the salt backup to get my sounds back and whatever other files I'm missing.
[G4 General] sdembiske:
Not sure why you'd want to go back to MM in the first place, given the lack of more up-to-date security updates - you could consider going up to the stock Nougat rom (from the Downloads section in the OP) if, for whatever reason, you really want to be on stock - at least you'd be somewhat more up-to-date.

As far as flashing your MM system.bin partition to restore your missing ringtones from your TWRP backup, I'll refer that one to [MENTION=5545101]steadfasterX[/MENTION].
[G4 General] mark324:
I flashed the system.bin but it never booted past the lg logo. Another thing I tried was extract the sounds from salt backup and placed them at the appropriate location in my phone, and that worked. As for the nougat stock, stock as in LG released Rom?. If so, I'll check that out. Thanks
[G4 General] sdembiske:
OK. The stock Nougat is here on steadfasterX's server: http://leech.binbash.it:8008/stock/LG/G4/

It was released originally on the Korean model but was ported over. For installing it, refer to the post by [MENTION=4253671]grantdb[/MENTION] at: https://xdaforums.com/showpost.php?p=75913373&postcount=12

Thank you but this rom its usu compatible built? I was suffering a Blue Screen of Death the last week but i managed to fix it ...i went to downgrade Nougat again...To give a example about my problem this was my processing flashing with twrp 3.2.3.0

Unlock bootloader with salt in lollipop stock ---->Flashing Cypher OS Nougat ----> i didnt i like it and flash Lineage OS 15.1 oreo usu compatible with h815..

Now in LOS 15.1 oreo i see my gamepad gamersir T2a doesnt work in that rom,so downgrade it again to the lineage you suggested but that rom give a blue screen of death.I didnt take any photo of my probem because i was reading in xda forums and they said if you can use twrp in blue screen error of death you can manage to install again using a usu rom compatible.

I will try to flash it again...

Edit2:Yep i flashed this rom lineage-14.1-20180517-UNOFFICIAL-h815 and boom!!! blue screen of death....but now im im cypher os nougat and its working fine....but i dont like that os :(
[G4 General] steadfasterX:
Consider to read the OP again because it's all written there especially when you flash a ROM which is not compatible with UsU . The ROM you flashed is not compatible so you need to flash the baseband package otherwise you will get the screen of death.

[G4 General] slinson:
I know for a fact I have a VS986, however in SALT "GPT Compatibility" shows H811.

Does that mean:

A.) I need to get **H811**_UsU_unlock.zip" and **H811**_UsU_baseband_flash-in-twrp.zip along with **H811** ROM?

or B.) I still stick with **VS986** unlock/baseband, BUT only **H811** ROM

or C.) I stick with **VS986** unlock/baseband/ROM all the time?
[G4 General] sdembiske:
Answer: B.) Not only H811 roms solely - i.e.

Only

the specific UsU VS986 roms from steadfasterX (refer to Model specific ROM threads in the OP or .... H811 roms. In order to avoid issues, however, stick with the custom roms in the Downloads section
[G4 General] barbaros:
i have done all of the steps with success. flashed fully usu compatible 29a zip. now my phone is acting weird. These are my problems.

- Double tap to wake almost never works.

- Power button doesnt work sometimes.

- Volume buttons does not work or the phone registers them late.

- Screen wakes for no reason. Multiple times in a row sometimes. (yes i have checked for any bad apps also its been happening since the first boot without any apps) Phone is idle, screen wakes without any notification .

- After powering up the phone, sim code screen comes after a minute or two.

Any ideas ?

Hello. I want to say big Thank You to Author of "UsU" unlock and his helpers. I have success with unlock, I have TWRP, i also flashed root, and so now I have H815 with cool TWRP access, and for now original as it was on it Android 6.0, rooted. Made TWRP backups too. Super nice. :) But, since it is not my "main" phone but rather technical toy, it is all about further experiments... :)) Searching and reading so far gives me two obvious UsU-compatible options: Cypher and Lineage. Right? What do I miss, maybe? For example, does UsU-Compatible LG G4 Lollipop exist maybe? Thanks !! :)

EDIT: i used SALT in that bootable Linux environment (cool thing). I consider interesting to note that, SALT said: my phone "does not support direct flashing", and i was worried i couldn't do a thing, but - UsU unlock went flawlessly.
[G4 General] fmmarotte:
My problems started at the beginning of October 2018, when my wanted to put the rom cm14.1-20161225-NIGHTLY-h815.zip G4 H815P (Brazilian model), the device was already rooted but did not have the TWRP. I no longer remember how things happened. There was a problem and Windows 10 no longer recognized it. At that time I did not know that when I modified the device it was no longer possible to update the official program of LG and also did not know that there is an official method to unlock my device. It no longer goes into download mode, goes straight to fastboot.

My first contact was on 20th October 2018, 08:02 AM | # 20 fmmarotte.

The last contact was on 7th November 2018, 12:06 PM | # 30 steadfasterX

around here; ---> https://xdaforums.com/g4/...t3797100/page2

When steadfasterX ordered that I look for the FWUL. I have never used linux, I had several problems, a lot of headaches, I managed to overcome and created the bootable USB stick and enter the FWUL and access the SALT. But to my disappointment my device remains unrecognized.

I apologize for the long text, always sleeping at dawn, reading about an operating system I have never used.

Currently the screen of my LG G4 H815P (Brazil) is like this;

Fastboot Mode

PRODUCT_NAME - msm8992_p1_global_com

VARIANT - msm8992_p1_global_com Toshiba 32GB

SECURE BOOT - disable

LOCK STATE - locked

[1280] Fastboot mode started

Please help. This situation is insufficient, disappointing

What is the difference between the ROMs that are named with/without UsU? I could build lineage-15.1 for h815. I tried it on my UsU'd h815. But it does not boot. So far I am using lineage-15.1_UsU. It works great. Now, I want to try my ROM. Let me know the difference.
[G4 General] opeller:
Hi,

Thank you for the great rooting solution! Really want to try it, and I'd be glad if you could answer my questions before trying it myself.

1. I don't need any of the data on the device. Do I need a backup? Full or just Basic?

2. I already went a head and did a full backup (through usb stick. vm got stuck several times.) it said

These files are corrupt (md5 mismatch):

userdata.bin

Should I worry? The phone was factory reset, didn't even go through with the initial setup (did do the first boot before backing up), don't need anything on it.

I also got a warrning saying several files couldn't be verifyed. Adding a screenshot, I'd be happy to make sure that's OK.

https://i.imgur.com/cEmQzy1.png

3. Is it OK to use this method on my phone? Adding a screenshot from SALT to make sure.

https://i.imgur.com/yEKiiNY.png

4. If I want to go back to stock after using a custom ROM, how should I do that?

(saw a post about it here but it was vor a different Vxxx version from what I see I have in SALT)

Thank you again! :)

(didn't add LOG since when copy+paste the text file wouldn't contain all of it for some reason, and uploading it from SALT failed)

[G4 General] sdembiske:
1). Partial if you don't need or care about your data. Full, if you do.

2). If you have a corrupt data partition it could create issues. To be on the safe side, you may want to use LGUP-NEW and re-install your stock KDZ(better yet if a newer version is available, a higher version letter in the alphabet, i.e. x - z, install that), before proceeding to unlock

3). Yes , if done properly and exactly.

4). Read the OP - you can't, except in certain instances. You can back up what you have installed after unlocking and installing TWRP.
[G4 General] conbak49:
I have finally gotten brave enough to start this process. I have flashed back to stock LP with LGUP, but I'm stuck there. When I start LG Bridge it recognizes my phone and tells me there is an update available but when I click to update, LG Bridge tells me it can't connect to its server. Is there some other way to upgrade to MM? I have an MM KDZ, but LGUP won't flash it for some reason. Do I absolutely have to be on MM or is there any way to do USU on stock LP? Thanks again for any guidance. Hoping to get this done soon so I can move from my old gPro back to the G4.
[G4 General] sdembiske:
Download an H81220(x-z, preferably) for your carrier for your phone (https://lg-firmwares.com/lg-h812-firmwares/firmwares/) and upgrade it with LGUP-NEW.
