Guys aoscp oreo has a known BUG which loosens the sim detection!!! Try with aoscp nougat first and for oreo there is an app by alaskalinuxuser about rild restart!

Please always keep in mind that oreo is brand new and even it is stable it still has bugs like Bluetooth issues and the sim issue!

Personally I do not use oreo as in my opinion it's not production ready for daily use even though for many ppl it is good enough.

Try everything first with lineage 14.1 and aoscp nougat.

The v29a ROM has issues on some models as we know.

I would recommend that the users having issues to boot / use v29a should try the f500 port or f500 system and f500 boot image

And another one:

The baseband package is needed only when you use a MM or N modem partition.

If you have issues regarding cell service:

Flash your modem partition of your SALT backup. If you were on LP before flashing UsU that's all you need. If you were on MM before flashing UsU you need to flash the baseband package afterwards.
[G4 General] fil3s:
I'm on crdroid 7.1.2 and everything is A okay.

Ps. I noted the cellular connection problem on Oreo and quickly flashed nougat .

Another win !!! :D

I did it in a VM. It worked fine.
[G4 General] Zambiemambie:
The requirements section states no required Android version, but in FAQ #9, You say that I need MM or LP.

I have an H815P on V29a with ARB = 0

Do I need to go back to MM before I try to flash UsU?
[G4 General] fates13:
Hey steadfaster, how would I go about restoring my stock lollipop system.img back on my phone after UsU unlock? Unfortunately I forgot to make a TWRP backup so the system.img is all I have to work with in order to get cell service back up on my phone until working Nougat rom specifically made for VS986 is out. I tried flashing the system.img in TWRP and fastboot but it failed to boot.
[G4 General] Abhishek_gkp:
Anyone Successfully Unlocked H818N.......
[G4 General] mwahahaa:
Thanks for the file -- I flashed the modem using fastboot but I still have the no cellular connection. I'm not sure if my problem is the same as others who can't make calls. It says "service disabled" on the lock screen and "mobile networks" is grayed out in the settings. wi-fi and bluetooth are fine, with no sound or video issues. I'm a bit lost as to what I should try next... I'm on Koodo (Telus) in Canada.
[G4 General] hey_joe:
So what you did is just flash the modem and nothing else? Which rom are you using right now?
[G4 General] mertklic:
Hi steadfasterX, After I did these steps|

--

Flash the baseband package now: <model>_UsU_baseband_flash-in-twrp.zip

While still in TWRP choose REBOOT menu and reboot to RECOVERY (yes again!)

Notice: TWRP will show your REAL device model when connected to the PC now.

--

I couldnt manage to reboot recovery, it rebooted the device THEN I booted into RECOVERY and now TWRP does not show my real device model. It shows`3.2.1-PREVIEW-103_g4_N`. Does this really important or should I continue? Here is the LOG. Thank!

Hey I'm making a tool to unlock h818 variant or you can say I'm trying to fix the touchscreen error, It's still a test, so I'm not totally sure that it will work or not but for that i'll need some h815 international variants, will anyone like to contribute to this project?

SALT can unlock h818 already so there's no need for another tool imho. H818 is just disbaled there but up to you ofc. How do you solved the touchscreen issue?
[G4 General] Aryan_Q:
Well I'm still working on the touchscreen issue 😅, I'll need more G4 to test
[G4 General] steadfasterX:
Ah lol.. Good luck.. I've asked for test devices since years but nothing ;)

Sir, I can understand how hard it had been to create something like this, I really respect your work in the development of this devices🙂
[G4 General] Aryan_Q:
I can't explain everything about this project because it connects to the servers of LG 😅 if I explain everything, there may be a chance that LG will fix that and we will never be able to unlock our bootloader

[G4 General] Mr Joegernaut:
My ARB Version is 20....am I SOL? I was able to boot into maid 4.0xx, update salt, etc. Obviously UsU wont proceed given it needs arb < 2.

Goal was to flash lineage 16 (updated security/no bloatware) and use the phone for wifi only/music player/etc around the house and car. I may just have to find another phone. It was laying around so I thought I would repurpose it. Probably going in the trash/recycle bin now.

VS986 (GPT H811)

Firmware: VS9862BA

Firmware System: VS9862BA_00

Andriod: 6.0, security patch 2017_05_01

Country: US

Carrier: VZW

ARB: 20...

If my LG wont work, anyone have recommendations for a easy to mod cheap phone preferably with sd card support? Removable battery would be awesome also but those days of any recent phone are long gone...
[G4 General] steadfasterX:
Share the SALT debug log (advanced menu -> upload button , share the link)
[G4 General] Mr Joegernaut:
I didnt see the upload button in the advanced menu so I just copied the debug log to a text file.
[G4 General] steadfasterX:
The button is at the bottom of the debug log screen....

Ok so it seems you have 2BA firmware and that has ARB 2. Could you pls do the following:

Select backup -> custom and just select aboot and tz. Then after the backup share these files here. They do not contain any personal data so no worries ;)
[G4 General] Mr Joegernaut:
Here are the files. Also when running maid nightly build from USB my display resolution is locked to 4:3 something really low. I suspect that is because of my nvidia GPU 3060-TI (proprietary driver) so I can't resize or move the salt windows small enough and why I missed the upload button at the bottom.
[G4 General] steadfasterX:
ok so you def have ARB 2. need to fix the detection for your special firmware in SALT..
[G4 General] steadfasterX:
ok I think its fixed and should work now.

follow FAQ 10 of the SALT faq and switch SALT into develop mode. then restart SALT and try again.
[G4 General] Mr Joegernaut:
Fixed now, was able to unlock device, flash twrp, and lineage 16. Thank you!
[G4 General] k24a1:
i am curious as i cannot open the svc menu on my LG G4 and i am unsure how to install SALT. i have a VS986 on software version 2BA (build number MRA58K) and i don't know how to check the anti-rollback on that phone. i would like to unlock the BL to install lineageOS.
[G4 General] Mr Joegernaut:
Run maid nightly from a USB stick, boot into it. There is a LG folder and salt there to handle the unlock process, then follow the guide here in OP to flash twrp and then your rom.
[G4 General] k24a1:
i am also curious, did anyone else find the rollback of 2BA on a VS986?
[G4 General] steadfasterX:
a quick search (https://xdaforums.com/search/30366379/?q=2ba&t=post&c[thread]=3760451&o=relevance)

points e.g. to:

https://xdaforums.com/t/unlock-unofficial-g4-unlock-any-lg-g4-device-with-usu.3760451/post-85862413

and as already said SALT is showing that (for the vs986 you have to update it to develop though. how is written in the SALT FAQ #10 ofc).
[G4 General] k24a1:
so i did get rollback 2 and i managed to get lineageos on here, but when I put a SIM card in the phone does not detect it. I have also installed the baseband. alsom LOS 16 feels laggy sometimes. anything i can do about these issues??
[G4 General] steadfasterX:
1) when installing an UsU based ROM flashing the baseband is NOT needed and can (rare) cause issues when doing so. Flash the modem from your backup again when using an UsU compatible ROM.

2) sim detection can take from 10s to several minutes after a fresh boot. That is a well known bug and i did everything possible to speed this up but it is sometimes fast sometimes not.

3) laggy .. That depends on millions of things. The ROM is made to provide a balance between performance and power safe which can never satisfy all users. Main reason for your feeling is very likely the apps you're using. When they consume too much RAM then android will kill others in the background which then can cause this feeling (as e.g the launcher needs to be restarted etc)

All ROM related questions are better placed in the ROM thread btw ;)
[G4 General] redgrass83:
Hello . Long story short I've got an 812 model. Been flashing The hell out of it it's bricking it after using the new nouget update. Everything is back running now but it's acting kind of funny on the official nuget USU.. random reboots and it doesn't like going from charge mode to starting up the OS it takes a few tries.. pretty sure my power

button is screwed, and there's no sound, again I might have screwed up the speaker connections those don't matter. Flashing a couple times I've noticed sound would come back. Like I said I'm not real worried about those issues I just use the phone for the apps to fly drones what I'm concerned about is I think it might be an incorrect kernel or maybe bootloader I'm not sure. All through this flashing processes to unbreak it it's been identified as an ls991, an 815 , but now. Everywhere it says 812 even in salt. .. so there's a little back story for my real question. Going to upload a picture of what it does sometimes on boot up. Please tell me what it is and what I can Flash to more stabilize it thank you. Btw I never post, figure it out myself usually but let me tell you you guys are really frankensteining lol, the g4 with USU. Love it. Flashed all day yesterday. 9008 a couple times.lol. anyways .thanks for any help anybody..isthisnormal? Or a clue as to what I'm missing? It doesn't like to stay in charge mode. Always wants to boot into os. Oh. And have to power up by plugging usb power in for a second . The. It boots right. Leave it in too long , and I get that weird battery thing.

Oh ya. It seems there's no more power input, to the power pads for the power button. I'm thinking Part of it is something Flashed from a different model. Probably bootloader or kernel, no?

Like I said I went around the world with it yesterday haha..so to speak .and literally. Lll
[G4 General] redgrass83:
it does say ARB 2.. so do it download the original 812 firmware and then hexedit, it , to match what lgup identifies it as? Then flash ? And if so, lollipop, or marshmallow? I forgot to add , yeah , it won't Flash with any lg tools. Invalid kdz . Really I just want to bring it back to stock and then come up the proper way. I do love it , It has brought New Life to it for sure.

What should I be heading back to lollipop or marshmallow for the first thing..?

Or is it just something I can flash to fix? Itz almost, pefect except for that one issue about the power having to be started with an adapter..

Salts new to me. :-(
[G4 General] bakdorbandit:
What is UsU
[G4 General] steadfasterX:
Something to eat. You can download it and print it and then just eat. It's even better with a sweet sauce if you like.

Really that question is so silly no idea what else to write .. The first posts describes everything in deep detail.
[G4 General] redgrass83:
At least he got an answer. . you'd think there would be info on maybe what to fastboot flash to get a stock phone back up n running normally. . what's the use of using salt if there's very little documentation on the real-world restore uses of it. .Gotta be a cut n dry way of explaining how to properly restore **** from the salt backup.. I mean it IS an OLD phone,....
[G4 General] steadfasterX:
Do i missed a q from you? Restoring a salt backup is by fastboot and there are tons of guide how to use fastboot but yea i could have done an own too.

EDIT:

Other then that this thread has a massive FAQ section and if you want to know how to go to stock consider reading them. especially FAQ 28) in your case..
[G4 General] steadfasterX:
For those who got catched by the LG unlock portal shutdown on 31th of dec 2021 before they were able to grab the official unlock.bin:

Yes, UsU works on official h815 devices, too with the exact same procedure.

Actually I made UsU based on an official h815 and it works like all the others.

So if you own an official unlocked h815 and do not have the official unlock.bin then UsU is the only way to unlock from now on.

Read carefully the OP and FAQ as usual.

Happy new year 🎉
[G4 General] steadfasterX:
hmmm seems xda didnt notified me on some posts in december.. anyways I try to answer:

> random reboots and it doesn't like going from charge mode to starting up the OS it takes a few tries..

this sounds like the ILAPO. I may be wrong but random reboots never occured on UsU'd devices. so it must be hardware imho. either ILAPO or something else.

> button is screwed, and there's no sound, again I might have screwed up the speaker connections those don't matter. Flashing a couple times I've noticed sound would come back.

well yea that really sounds like a hardware issue which also likely means your random reboots are related imho.

> Going to upload a picture of what it does sometimes on boot up. Please tell me what it is

> isthisnormal? Or a clue as to what I'm missing? It doesn't like to stay in charge mode. Always wants to boot into os.

the first pic is likely the charging animation which does not load properly. I think that a fix in the ROM is needed for that. nothing you can do on your site regarding that (other then using STOCK likely).

the second is something explained in the OP topic "Changes in behavior".

> and what I can Flash to more stabilize it thank you

at this point I do not think that you can stabilize your device by software. I mean you can try going back to stock as explained in the FAQ but I dont think this will solve all your issues.

> Oh. And have to power up by plugging usb power in for a second . The. It boots right. Leave it in too long , and I get that weird battery thing.

that sounds like a contact issue. as you screwed up your power button there is not much help you can get here I guess. This is actually not UsU related.

> Oh ya. It seems there's no more power input, to the power pads for the power button. I'm thinking Part of it is something Flashed from a different model. Probably bootloader or kernel, no?

UsU is explained in great detail here: https://xdaforums.com/t/unlock-unofficial-g4-unlock-any-lg-g4-device-with-usu.3760451/post-75817534

> it does say ARB 2.. so do it download the original 812 firmware and then hexedit, it , to match what lgup identifies it as? Then flash ? And if so, lollipop, or marshmallow? I forgot to add , yeah , it won't Flash with any lg tools. Invalid kdz .

well you should have read the OP at least until you understood that you should never ever use lgup again after UsU'ing the device. you can be lucky that lgup failed.

> Really I just want to bring it back to stock and then come up the proper way. I do love it , It has brought New Life to it for sure.

Follow FAQ 28

> What should I be heading back to lollipop or marshmallow for the first thing..?

Hi please Help Me.

I have this Messange,

Salt 3.24 - No Support Me Device LG G4 H815.

Please send me next Step Me.

Dear Users XDA Forum. Please Give me Support. Me Device Micro SD Card no Detected

Tools fdisk -l in Terminal Consol Arch Linux / FUEL By Mr. SteadfasterX Dear Developer.

I have messange Me Device SD Card 31 GB No Mount.

I confirm that I am using the console and after typing fdisk -l I cannot find the 31 GB Micro SD Card disk. From the depths of my heart, I am asking you for your support. I am asking for directions, how can I make the command that the 31 GB Micro SD card mount to me as a portable disk? I am informing that I use Linux Ububtu on a daily basis and know the commands for Ubuntu Linux, I have contact with Arch Linux for the first time here.

How should I install the Micro SD card device in the console / terminal? My question is based on the instruction point - which says clearly that you should prepare a memory card / format to vfat format - this is what the instruction says. So here has already come a challenge for me. From the bottom of my heart, I am asking you to help me get the best effort to pass my challenges best.

I'm Confirm here Windows No Available Option Format SD Card to vfat - file format.

There is no this option even available in the Disk Management Menu - not even from the Admin account.

Please Give me The Best Support Me.

What did the Dear Post Author of Steadfast X mean when he wrote that you need to format the memory card to vfat format? Can any of you help me, how would I do it?

Could I use a Linux other than Linux Arch - to try and format the memory card to vfat format? Sorry, Linux Arch doesn't detect my Micro SD memory card correctly, I can't read the disk after typing fdisk -l - even when I log into the console with Admin account.

My second Iphone 7 Plus smartphone breaks down. I have to get this Iphone serviced in some time. Can you help me ? I urgently need to upload Android updates to the LG G4 H815. Could you please tell me how should I format the Micro SD memory card to vfat format?

If, after logging in to the Admin account on the console / Terminal, it does not detect my 32 GB memory card - which is correctly detected in Microsoft Windows 10, after connecting the LG G4 H815 Smartphone to the Laptop with a USB cable?

Should I download an additional application, a tool for Windows 10, so that such an application will allow me to format a 32 GB memory card to vfat format according to the instructions provided by the Author Dear SteadfasterX?

Is there an application for Microsoft Windows 10 - on which I can successfully format the memory card to vfat format - i.e. fo such a format - as required to proceed with unlocking the LG G4 H815?
[G4 General] Radoslav 1608:

It informs that in the Linux Ubuntu Console after logging in to the Admin account - I also cannot access this 32 GB Micro SD card. Despite typing fdisk -l on the logged in Admin account, it cannot find this disk for me. So I can't go any further from the Linux console to format this disk.

Hello,

Sorry for this, I am a complete noob and haven't dealt with custom ROMs for a very long time now so it's like starting from scratch for me... I have a stock G4 H812 on Android 6.0 - searching here on XDA it seems like it was a bit troublesome to unlock the bootloader but apparently it's doable now.

I would like to install this Android 10 ROM.

On the first post it says that I must download the TWRP accordingly but it only shows up to Android 9. Which one should I get since I want to install an Android 10 ROM?

Also:

I am not sure how to check if I have v20x or higher, the phone says nothing about this.

Can anyone help me?

Thanks!
[G4 General] tonapi:
Hi i have Lg G4 H815 European version, it's possible to unlock bootloader? thanks
[G4 General] steadfasterX:
I told you where to look at. FAQ 28. It has all the fastboot commands needed.

Use the latest TWRP preview for pie.

You can't check easily what bootloader stack is installed. To be sure about the easiest is to flash the bootloader stack needed. How depends.

If you haven't UsU'd yet ( that was not clear in your post) then it would be the easiest to just flash that stock version by LGup.

If you have UsU'd the device already you would flash just the bootloader stack in TWRP:

https://leech.binbash.rocks:8008/stock/LG/h812/20x/

--> h812_20x_ARB-0_UsU_bootloader_TWRP-flashable.zip

Ensure you use the UsU one not the other!

Sure and its the only way now to unlock when you do not had the chance to get the official unlock bin before they had shutdown the website. The OP requirements shows that its supported and UsU was even developed on a h815 international.

thank you...
[G4 General] steadfasterX:
Do you see any? If you find one let me know.

No idea what you did. No idea in which state your device is. Invalid ram console usually means you have a lollipop bootloader stack flashed. You have to flash the MM one. Otherwise check if deepl.com works for you for better translation of your language
