yes. the detection is correct now!

if windows is still showing crap its the windows cache for that device (sorry no idea how to fix windows here)

.
[G4 General] lHemaNl:
Ok, thanks for checking. You right. I connected phone to second computer and its name is LG H815, so like you said it has to be Windows cache.

Thanks once again :) .

I have already done this guide few months ago:

https://xdaforums.com/g4/general/guide-upgrade-h815-locked-bootloader-to-t3684945

Do I need to downgrade to MM to make this work? Is there anything else I need to know?

Thanks!!
[G4 General] andy55:
I'm having a heck of a time trying to get a rom to load on my g4. first off its a us991, followed directions and unlocked, have twrp installed etc.. anyway tried loading a gpt compatible rom, had to edit the updater script to load but no matter what rom I try the phone will get stuck on the boot animation, and cant get past it. what can I try to resolve this issue? I haven't found any yet but are there any us991 compatible roms out there?

thanks, and thank you steadfaster for making this even possible
[G4 General] steadfasterX:
Consider to read the OP for an answer and the faq for any further ones.

You flashed the latest MM modem for us991 and then the baseband package in TWRP?

Do you have for sure MM bootloader stack?

If so try the N modem plus the baseband package.

Ensure you choose a ROM which is shown as compatible in SALT.
[G4 General] smurf_1:
Hey steadfasterX,

Sorry, I didn't mean to ask something that was already explained, but I even read the post again and I still can't find the answer. Or maybe I just don't understand what part answers my question exactly.

I currently have a stock nougat that I installed without unlocking my device. I would very much like to unlock it with your guide and install a custom ROM, but I want to make sure that I can do it without any expected problems and if there's anything else I need to do before such as downgrading to MM.

I would really appreciate if you can point me to the exact part where you've answered that question, also, if I do need to downgrade to MM, is there a recommended way of doing it?

Thank you very much for this, really appreciate it.
[G4 General] andy55:
phone was on 25a before I started, so yep it was MM. In salt it showed compatibility with 811, so those are the roms I'm downloading, tried an oreo and nougat rom. and I've tried flashing the N modem, then the baseband package after flashing the rom, and still it'll just hang at the load screen. after about 15 mins it restarted back to recovery.
[G4 General] FpsAndrew:
Could you make a video tutorial for Newbies like me? Like this is too much information when I read it. I'm a visual learner, thanks.
[G4 General] steadfasterX:
Requirement #3 ;)

And you tried the MM modem plus baseband package as well?

No. It's crucial important to READ. This can't be done in a video.

If that's too much I strongly(!) recommend to keep locked.
[G4 General] sdembiske:
Refer to post # 361

While this post was written specifically for the H812, if you substitute your device model and roms specific to your model/GPT compatibility it may provide you a method to try to solve the issue. Start at the paragraph beginning with, "- IF, you've already installed the rom and are having problems ..."
[G4 General] andy55:
thanks for the help into this issue, but flashing modem from 25a didn't help either, it still hangs at the load screen then after about 15 mins reboots to recovery. So I decided to restore back to marshmallow, ran my restore and all went well but now my baseband and imei are missing. I tried reflashing the modem again and the baseband zip in twrp and nothing, its still shows as unknown. I'm downloading a stock kdz now to see if I can extract the 24a modem and try that but aside from that I'm kind of puzzled why that would be lost. Good thing I have a backup G4 to get me through :)
[G4 General] sdembiske:
I'm assuming you followed the steps completely that were listed in the post I referenced and the MM modem you flashed was from your SALT backup/extraction,

only

? I can't account for the loss of your baseband and IMEI other than perhaps the Misc partition got wiped or ... ? What rom were you trying to flash? - it will help if you can provide more detail, i.e., exact steps you did, what rom(s) you tried to flash etc - to give steadfasterX and other members more information to work with to help solve.
[G4 General] steadfasterX:
first thanks for putting this all together for other US991 users! greatly appreciated! :good:

some notes:

I strongly recommend to use SALT to extract KDZs and not that mentioned windows tool as it WILL have issues when it comes to other partitions

SALT is included in FWUL already so its very easy to setup and use

No use the latest TWRP. LGUSUxxxxx is shown in adb only and thats expected behavior in newer TWRP versions. when you open the devices storage in a file browser you will (should) see that the model gets identified correctly. If thats not the case: boot to the latest TWRP and share the recovery.log (see my signature)
[G4 General] tacticalcoconut:
Oh shoot sorry, I didn't play around with SALT enough to know that it could extract a kdz. I've updated my post based on what you said
[G4 General] andy55:
thanks coconut, that helped me out, for whatever reason my device wold hang on the load screen then reboot to recovery, I guess rebooting recovery in between flashes makes all the difference.

edit: anybody know any tricks to get exposed and gravitybox working with the stock nougat rom?!
[G4 General] tacticalcoconut:
I got xposed working on stock by first installing magisk, and then installing systemless xposed through magisk:

https://xdaforums.com/xposed/unofficial-systemless-xposed-t3388268

Basically after installing Magisk through TWRP, you'll have to download and install the XposedInstaller apk, and then in the Magisk Manger app, go to Downloads and search for Xposed Framework.

Install the Systemless for your SDK (I believe stock is based on Anrdoid 7.0, which should be SDK 24).
[G4 General] andy55:
Thanks, that's exactly what I did to get it going, but one more issue has come up. I set up the phone on stock 7.0, had xposed, magisk etc running fine, all before I put my SIM in, only checked to make sure my imei was fine, which it was. Tossed my SIM in and have an unknown baseband yet imei Read's fine. So I can't make phonecalls, but text works and data works. I call out to another line, it shows that the call goes through but I have zero call audio, no dialtone, no ring, nothing. I followed your steps to the letter and no dice I can't get it to register a baseband.
[G4 General] steadfasterX:
baseband unknown is not that evil. its ok and I have it here too.

here some things to try:

try to register manually and search the mobile networks. give it at least 5 min after you select a network manually.

if it says no network available or similar try to reset the APN to "default" & reboot
[G4 General] tacticalcoconut:
Oddly enough I had the same issue in stock AFTER I installed the systemless Xposed. I just said screw it and switched to AOSCP, and everything works perfectly.
[G4 General] mwahahaa:
Did you check the APN? I had to set mine manually before calls would work.

I had no problem with xposed installed through magisk.

Flash Oreo or Nougat from Marshmallow?

[G4 General] TheWarmBreezy:
I UsU'd my phone so I could flash AOSCP but I'm having issues with calling. If I wanted to go back to stock (the ROM my H812 shipped with) would I flash the G4_ARB-any_v29a_FULL-STOCK-ROM_UsU.zip ROM? Thanks to whoever can give me advice
[G4 General] nummer:
Hmm, depends on what model you have ;)
[G4 General] steadfasterX:
You would flash the boot, system and modem partition of your SALT backup.

Verizon LG G4 Revert UsU to Stock

Long story about getting from Lollipop to the latest Marshmallow on a VS986 and have everything work (cell, GPS, BlueTooth, camera, Wi-Fi).

In the event someone else needs to know this, I was able to UsU and Magisk and XPosed my Verizon G4 yesterday, and screwed something up trying to get it to uninstall XPosed to get around SafetyNet. It got stuck in a boot loop. I was originally on Lollipop VS98613B rooted and XPosed. I used LGUp 1.14.3 to update to VS98624C MM Stock (losing root and XPosed on purpose). Then after a few hours of OTA updates to get me to the last update of VS9862BA, I was ready. At that point I had an ARB of 2. Fastforward to my boot loop. I figured wth, it's broken now anyway, and proceeded to mess with LGUp some more. I was able to get it to flash VS98624C again. That removed UsU (no more Fast Boot mode by power off->Volume Down + USB data connection), and removed TWRP (no more TWRP in Recovery Mode by power off->Volume Down + Power button). Then I figured I'd try going straight to VS9862BA with LGUp. That errored out, so I tried the next version back that I managed to find. VS98629A (MD5 = ffdb116d1d4c5132beea97f7c8333f25) worked through LGUp! I then let it take the OTA to VS9862AA (304.3 MB OTA, optimizing 39 apps), then VS9862BA Marshmallow 6.0 (37.4 MB OTA, optimizing 41 apps), and I was able to UsU and TWRP and Magisk and XPosed again. My ARB is still on 2.

I did have to manually flash modem.bin (MD5 = 3621badbc57132280ff283b8c1a7c795) to get my Verizon SIM (cell signal) to work. You can do this at any point in the process.
[G4 General] sdembiske:
If you have a copy of your KDZ or can download one for your specific phone model, version and carrier, you can extract it in SALT and get the necessary files. It takes some time to extract all the partitions (allow up to 6 hours or so to do the full extraction of all the partitions - then keep it, you don't know when you might need it).
[G4 General] andy55:
You can not flash any stock image, but with 29a I haven't had much luck getting calls to work on my us991, so I installed rr 8.1 and have had no issues. Give 29a a shot and see if calling works for you, other then not being able to have any audio in call everything else worked perfect. If I mess around with my apn setting I might have more luck

twrp doesn't detect my model number

Hi, can anyone help me? my twrp doesn't detect my model number even after doing the solution in FAQ 25). I would post my recovery log as well but i can't since I'm a new user.

I'm currently running stock MM rom from LG (not sure which version) and my device is unencrypted.

Any help would be greatly appreciated.

Thank you

https://justpaste.it/4ly9l (recovery.log)

Tried to flash any UsU ROM but failed due to Error Status 7 (model detection is wrong on device),

even tried the "fastboot flash laf laf_UsU.img" and "fastboot flash raw_resources rawres_UsU.img" from H815_UsU_unlock.zip but still same error.

Any suggestions?
[G4 General] steadfasterX:

Dear sir

Could you please give me a hand.

Sorry for my poor English. I using a LG V10(F600). I looking for a way to root my phone, then I find your thread.

I make my phone into 9008, and then use QFIL flash F500's UsU aboot to F600 with other partitions from F600. After that my phone dead. It just vibrant a short second and nothing happen. Even I connect it to USB, there isn't any device would found.

I can make it get in 9008 again when i connect the test point. After flash F600's aboot, it still dead. Do you have any idea?

Thank you so much

LG F600S30d ARB=0
[G4 General] steadfasterX:
Ok so that flashing is fine..

could you pls try some of the earlier preview TWRP versions?
[G4 General] alexanderzhang:
Dear sir

Could you help me?
[G4 General] steadfasterX:
No.

EDIT:

Just to clarify for the others reading this. I answered his PM before he wrote here where he had the exact same question.

So there is nothing I can do for him.. He have taken the risk of trying something and lost. That's all.
[G4 General] Alphaclank17:
Update: So I've managed to solve this problem on my own. Turns out, all I needed to do was to flash an older version of TWRP (version 109 if I'm not mistaken?) and then only FWUL could detect my device model. If any other person is having the same issue as I did, I would definitely recommend trying this method.

Hope you all have a nice day.

?
[G4 General] steadfasterX:
Could you try the latest official as well?
[G4 General] Alphaclank17:
Yeah I did but the latest version of twrp wouldn't detect my device model so that's why I tried to use the older version of twrp and it finally detected my device model
[G4 General] steadfasterX:
Yeah that's what I recommended to do to find out the real reason. If you have the time :

Anyone with an UsU'd device could you try this :

Use the latest official TWRP then when booted:

adb shell
cat /proc/cmdline

paste that output. I believe I know where I made the mistake.
[G4 General] bdasmith:
I messed up possibly!! I wiped the system partition and now when I try to flash aoscp 812 version it errors and says no digest file found, e3004, error 7

please give a little hint as to which direction to go please. Sorry to bother everyone, but my brains kinda locked up on me....
[G4 General] Alphaclank17:
I see, by wiping the system partition, did you mean that you cleared your dalvik cache or you accidentally went and wiped your system partition?

Also, the way that I managed to flash the aoscp rom onto my h815 is by flashing the usu rom that was available first, and then I flashed the aoscp one based on android 8.1. Make sure to remove the assert line first before flashing the zip file and double check the updated script to make sure that the file is not corrupted.

Hope that this will sort your issue out.
[G4 General] bdasmith:
it was the system partion....in twrp under wipe, i was in advanced and not thinking checked the system, along with data, storage, dalvik cache and cache.
[G4 General] Alphaclank17:
Aw damn, you didn't make any backups before you did that didn't you?

I don't think that I can help you if you cannot restore your previous backups
[G4 General] bdasmith:
I cannot find my backups! I did them, but I cannot find them where I thought I saved them! oh man.

edit:

I suppose maybe I should post this in the thread for aoscp for the h812.....
[G4 General] bdasmith:
I removed the assert line and it now installed!

[G4 General] steadfasterX:
thanks for reporting but this must be fixed.. and here I cant reproduce it so I need this from you:

Use the latest official TWRP then when booted:

adb shell
cat /proc/cmdline
dmesg > /tmp/dmesg.txt
exit
adb pull /tmp/dmesg.txt

paste the output and paste the dmesg.txt to http://bpaste.net (expiry = 1 month)

thx
[G4 General] hamudiz:
tried using adb but unable to get to output "dmesg > /tmp/dmesg.txt" (Error Bad Usage)

Used Terminal in recovery instead. Hope this is what you're looking for. :fingers-crossed:

once booted i need the recovery log again ..

thx

Done, attached is the recovery.log.

Tested and able to patch ROMs on the new PREVIEW 125.

Thanks!! :D
[G4 General] steadfasterX:
Great so does the fix works for you? Unfortunately you have attached the wrong recovery logfile could you please verify and ensure you attach the latest one of TWRP build 125? By the way it's always better to use http://bpaste.net
[G4 General] alexanderzhang:
it's risky.

Now I have some new condition. I can use the F500 UsU aboot make system boot up, but touch screen is Chaos. I can't control it. Do you have any idea?

Pea zip is the only one to extract them... And Virtual Box cant read it..

Thoughts?
[G4 General] steadfasterX:
No the server is fine. Wrong thread btw.

Check the md5 this is a client issue not mine. Very likely a antivirus issue which tries to scan the thousands of files within FWUL.

I need to know which exact firmware version you had installed before UsU'd .

If you do not know exactly grab that info from your backup (requires Linux/FWUL).

Open a terminal in the directory where you have your SALT backup before UsU'd.

Then:
