Hello. A couple days ago, I posted that I successfully unlocked my Lg G4 H812 device but I didn't root it or flashed a rom .

I did flash the G4_29a_N_modem_UsU.zip. I then flashed H812_UsU_baseband_flash-in-twrp.zip.

Now, when I try to get into twrp, I get a display showing the imei number. So I guess twrp is gone. Also, the sound is gone. I tried to make some adjustments in settings, but still nothing. However, on bootup there is still the secure boot error, so it looks like the bootloader is unlocked. If anyone can help me fix these problems, it would be appreciated. Thank you.

Use the search and find the useful posts of sdembiske. H812 is special.
[G4 General] sdembiske:
If you cannot get into TWRP at all, can you get into fastboot mode? If so, flash the TWRP recovery image, i.e., unzip the TWRP folder that you downloaded and open the resulting folder. Re-name the TWRP recovery image inside to recovery.img and copy it over to your adb/fastboot folder. Open a command prompt there, with your phone connected in fastboot mode and enter the following:

fastboot flash recovery recovery.img

Once you've got TWRP back refer to post # 361 and follow exactly the " IF, you've already installed the rom and are having problems ..." suggestion, for the rom (if not the AOSCP N rom) that you've had the trouble with.
[G4 General] stsz1954:
Problem seems to be fixed

Hello Sdembiske. I went through the thread and decided to follow the suggestions in FAQ #19. I went into fastboot mode and flashed the items mentioned in the salt backup. I then reflashed twrp and then the H812_UsU_baseband_flash-in-twrp.zip. I now have twrp and sound back. Do I still have to have to rename,copy and flash twrp again? I would like to install the ascop H812 rom. Do I need to flash anything else beside the kernel, modem.bin file and the rom? I appreciate the response and help I have so far received.

Hi,

my phone isn´t booting up anymore. QFIL says: "Download fail, Sahara FailDer Wert darf nicht NULL sein

Parametername: key

Why I can´t resetting it again with QFIL?
[G4 General] sdembiske:
No, you do not have to install TWRP back if you have it now.

Do not flash the latest H812 AOSCP rom just yet - I have had problems upgrading to it and steadfasterX is looking at the logs, so hold off for now. Flash the earlier dated version.

Remove your screen locks and then reboot into TWRP and do a factory wipe

&

data format in TWRP > then flash the

earlier

dated H812 UsU AOSCP version > flash mini-open-gapps > power down and reboot into fastboot > flash the H812 UsU AOSCP N kernel > flash MM modem.bin file from SALT backup > fastboot reboot.

If all good, reboot into TWRP, flash the SuperSU zip and the Xposed installer zip from the links referenced in post # 361 and go through the post, reading the other posts I have linked to get fully set.

Because qfil is evil. I wrote millions of times that using qfil is f*** dangerous and shouldn't be used!

It can CONVERT your device or blow fuses! Never ever use qfil unless you REALLY understand what files you flash. This requires to analyze the files you trying to flash with qfil. which is something 99% of the average user CAN'T. Which means: do not use it unless you don't care about damaging your device ofc..

The only valid way is using my sdcard unbrick method but as you already used qfil you may have damaged your device already.

If you UsU'd your device there is even one more reason to NOT use qfil. As said you shouldn't use qfil anyways but when you UsU'd your device it's even more worse.

Damn ARB v3 ... well thanks for your quick answer, I guess I'll get a new H815 device
[G4 General] Mahziyar:
Any good news for H818P? :p

I have H818P with ARB=0 and i installed nougat V29A , can i use this method after return to marshmallow ? i know stable file for H818P isnt exist now
[G4 General] runningnak3d:
If [MENTION=5545101]steadfasterX[/MENTION] can get his rear out of work and help me, bootloader unlock is coming for any LG phone prior to the V30, no matter what ARB version, and an engineering aboot is not needed.

lafsploit 2.0 coming soon(c).

How do I boot FWUL ?

I wrote FWUL on usb using Rufus, but my usb was converted 32gb to 64mb.

I'm trying to boot FLUW , but I don't know what to do.

I'm in this screen :

[G4 General] Tros13:
Hi,

I have a VS986 running 6.0 (H811, ARB2). I have tried UsU twice and both times everything goes fine, phone boots up, but the phone says "Service disabled." Seems like it just doesn't recognize the SIM card. Wanted to double check things and make sure I am following along correctly.

Does TWRP need to be installed to the system? Both times I decided not to because I was going to install Magisk, and I thought it was best to keep a clean system image if I don't plan on unofficial ROM use for now.

I used the TWRP Install button for the baseband package of my phone. Does this need to be done a different way like through the TWRP command line? If so, what is the destination for flash? Baseband? Radio? Modem (I noticed I have 3 modem partitions - 1.modem, 24.modemst1, 25.modemst2)?

I have read 5e of the FAQ and don't want to do anything else until I know I should be okay up to this point. The stock UsU VS986 kernel available is for nougat, so if the advice is to switch to that, do I also need to flash nougat? Or as far as "flash the modem partition of your SALT backup before flashing UsU (nothing else!)" goes, how do I go about that?

Sorry for so many questions. I am just trying to understand the process fully for the future. If you're lucky, maybe I screwed up early, and you don't have to worry about the rest of my Qs. Thanks!
[G4 General] sdembiske:
TWRP is installed to 'recovery'. In fastboot the command is: fastboot flash recovery twrp.img where 'twrp.img' is the image file name in full. It's in the OP - suggest you re-read everything carefully again ...

The baseband zip file is installed/flashed in TWRP using 'Install' - it will put it where it needs to go, so don't worry yourself about it. Just select 'Install' in TWRP, select your baseband zip file and install/flash it.

The modem file is taken either from your SALT backup of MM or from the right MM kdz for your carrier/phone model that you have extracted ONLY in SALT. Flash command in fastboot: fastboot flash modem modem.bin (or modem.image from the extracted MM kdz).
[G4 General] Tros13:
No, I mean after the flash. I flashed it successfully to recovery. When you open it for the first time, TWRP asks if you would like to install its files into the system. Didn't know if that could be why my install of baseband isn't working.
[G4 General] sdembiske:
You can ignore that, just tick do not show this again and swipe to enter TWRP, if I'm understanding what you're referring to now.

The baseband issue has nothing to do with that. It is most likely a result of your current modem file or you need to apply the APN settings in Android for your specific network carrier (you could check that first, before flashing the modem file).
[G4 General] TheDerpyLlamas:
Is this a joke?

Actually no it's not a joke.

Anywhere i can go to follow that unlock research progress?
[G4 General] sdembiske:
There is this thread for the H918: [ROOT] - lafsploit - H918 (any version up to and including H91810t) but the one in the next paragraph has some current comments with respect to G4 bootloader unlocking in general with his process.

Addendum

: While he may not be ready to share the latest on a separate thread yet,

he is discussing some current progress on this thread

: LAF (Download mode) What is it, and how can we root with it? - his latest discussion is on post # 993 in that thread.

steadfasterX has been overwhelmed with work here and on his other projects, getting us to where we are now ... and has not been able to fully address this new potential process.

[G4 General] steadfasterX:
Hm sorry but I don't understand your issue.

When you have unlocked your device (officially or unofficially) you can install TWRP at any time.

When you have unlocked your device officially (the link you posted is the official unlock) then this is the wrong thread.

This thread is about

unofficial

unlock

not

provided by LG.

[G4 General] whitewolf1608:
I understand and can you help me find the correct thread for this method

I used to unlock?

I am a novice user on the forum and have trouble with the efficient

searching for threads on the forum.
[G4 General] ingcolchado:
I wouldn't worry about posting it, the vast majority of people that want to unlock their LG bootloader will try that first, and it is a very well known method to unlock it (official) for EU phones (as far as I remember), I tried that first since I got my motherboard replaced thanks to that infinite reboot issue, and I expected to be able to unlock my device with the official method but no luck, so I went on to XDA and found what I needed and got great help from steadfasterX
[G4 General] whitewolf1608:
Dear ingcolchado, I am asking you with a very polite request to send a link to the TWRP Recovery installation step by step. if there is no such detailed instruction then I am asking you to write such a manual here in response to my post.

Which version of TWRP Recovery should I choose and upload to LG G4 h815 if I have never uploaded an update to My Android 6.0 Marshmallow

I am asking you with a very polite request for a link to the appropriate TWRP recovery version

and to the appropriate Super SU version for uploading Root.
[G4 General] ingcolchado:
Didn't mean to be rude, and didn't got what you were asking

search for Twrp in the internet, you'll find the main page and there you can search for your device and download the appropriate version

And just flash it in fastboot

fastboot flash recovery <twrp.img> (replace <twrp.img> with the real filename)

If you don't find what you're looking for, search on Google: xda lg g4 twrp

And read everything you find until you're sure what you're doing, tough it is a very basic step that you should have taken already

There's is no simple explanation nor guide since it's a risky (yet simple) procedure and you may brick your device and nobody will take responsibility for that, and most people here knows what it involves so there's not a step by step guide

You have to search for what you want and if there's something you don't understand, search for that, until you are clear on everything or at least decided to try it despite the risk

Here it is understood that if you got to XDA you know what you're doing especially the risks, and if you're not willing to take the risk to make your device unusable, then you should not try anything that you find here on XDA
[G4 General] Tros13:
Could anyone point me in the right direction for how to do this? Verizon disables the option to manually add an APN. build.prop file editing? what of my current settings do I need to figure out?
[G4 General] sdembiske:
Google your specific carriers access point settings - normally on their web site somewhere.

In android > Settings > under Wireless & networks heading > ... More > Mobile networks > Access point names > + sign at top of screen > once you've entered the correct information that your carrier provides touch the 3 dot menu at top right of screen and Save.
[G4 General] Tros13:
Default disabled, both before and after UsU.
[G4 General] sdembiske:
OK - understood now.

Try editing your build.prop file by adding these two lines at the bottom:

ril.sales_code=LOL

ro.csc.sales_code=LOL

In order to edit the build.prop but more importantly, have it stick on reboot, follow the guide I've referenced in the TWRP-in-FiSH thread in this post: 357

It will work in TWRP as well. steadfasterX references the post in his TWRP-in-FiSH op under List of confirmed flashing experiences .

Then follow the guide I posted above and see if you can now make your changes.
[G4 General] firefalconw:
eyyyy am finally on a custom rom :D

great work, way easier than expected

thanks again
[G4 General] firefalconw:
no sim card

soo everything is working properly now except that i cannot detect a sim card

am running on the latest lineage nougat build,

i have the H815p arb = 0

could the rom be the problem or is there anything else i can do?

help would be much appreciated
[G4 General] steadfasterX:
what ROM version do you had installed before you UsU'd your device? MM or LP?

-
[G4 General] firefalconw:
i had the stock lg marshmallow rom
[G4 General] steadfasterX:
ok.

and how did you flashed nougat? which exact file do you had used?
[G4 General] firefalconw:
ok so after i UsU'd and installed twrp

i flashed the baseband package

then Flashed G4_29a_N_modem_UsU.zip and the baseband package again

then i finally flashed the lineage zip

i used the links in this thread to get all downloads including the rom

this is where i got the rom: http://droid.binbash.it:8008/lineage/nougat/h815/
[G4 General] steadfasterX:
On that current state just Flash the genesixx LOS build
[G4 General] firefalconw:
Great its working now,thanks alot

Cheers

After i unlock my phone, all the app from bank can not pass the security check even i use magisk is there any way to let them work?

My G4 is running with official nougat
[G4 General] fil3s:
Which variant

You could try a ROM that passes saftetynet. You can find some here I use RR 5.8.5 N and have no issues
[G4 General] fitztu:
for example this

https://play.google.com/store/apps/details?id=tw.gov.post.guard

this is the app from Taiwan post it dose not run because of the unlock.

could you do the test if this app running on your handy?
[G4 General] fil3s:
Yes i don't know what the app is (I don't know Taiwan language) but it runs on my H815
[G4 General] quinnby95:
Best ROM to use?

Hey Everyone!

My girlfriends best friend has an H812 and is wants to maximize his battery life and make his phone last longer. He's not very techie but he has heard about custom ROMs etc. I have installed Official Lineage on phones before that officially support unlocked bootloaders. Because using UsU is a totally different ball game I wanted to get your guys opinion, what is the most stable ROM to put on there that will help with his battery life/longevity of the phone? I would like to give him Oreo but Nougat will do if that's best.

Thanks!!
[G4 General] fitztu:
It says "your device was be rooted and it cause security problem. Please check the Authority of your device."

But it run!!!!! maybe I can just hide the root for this app then it work!

Which root app are you using for Root magisk or supersu?

Thank you!!!!!
[G4 General] fil3s:
Magisk 16.0 but I pass safetynet. :good:
[G4 General] spartan268:
I would recommend sticking with stock if that person is not a techie. The most overall stable rom would be aoscp nougat but I say just to leave it cause they're a few loops to be jumped around and it'll completely change up the user experience. Plus do you really wanna be held liable if something goes wrong? :P
[G4 General] steadfasterX:
Short Announcement

h810, h812, h815, vs986 aoscp nougat 4.2 UsU ROMs online!

UsU ROMs do not need baseband patches or UsU kernels. They will just work. Best with a pure untouched() MM modem (h812) or N (h810, h815).

As soon as my time allows I will open threads for every model!
[G4 General] sdembiske:
Thank you - latest aoscp_h812_usu-4.2 April 12 version booting up properly now (allow 6-8 minutes boot-up time). Rom is working like a charm.

Much appreciated.

S.
[G4 General] gh0st:
Thank you for this. I never thought Id see the day my G4 gets a custom Rom.

Having a bit of trouble though, I can install the rom and boot, but having issues when logging into google after flashing gapps. Crashes with the error invalid ram console.
[G4 General] steadfasterX:
Sounds like you have still the LP bootloader stack?

What model?
[G4 General] fitztu:
Is H815 baseband support all channels 2ca? Or this baseband only support 2ca in europ?

Or all kind of h815 are the same?

Because when unlock and move to official 7.0 I can not get 4G+

My Telecom operator is with 700(B28) and 1800(B3).

How could I solve this problem? should I flash modem.bin which I back up with SALT form MM instead?
[G4 General] gh0st:
H812, unlocked the phone when I was in stock LP. The compatibility in UsU shows H811 if that matters.

Using stock LP modem to boot, otherwise crashes.
[G4 General] steadfasterX:
Read and follow FAQ #20b)

.
[G4 General] vsTerminus:
Thank you!!

Up and running on H812 with the factory H81220x (MM) bootloader stack and modem. No baseband package, no custom kernel :)

As for video playback and recording, still broken. There are some third party camera apps which can record videos that play back properly, but YouTube playback is still affected. Anything standard definition (Up to 480p) plays fine in YouTube, but anything HD (720p+) simply won't play at all for me. I imagine that has something to do with the codecs and/or DRM that HD videos are encoded and protected with.

Looking into it a bit more, the H811 users had this problem too a couple years ago with LineageOS 13 when version H81120o's modem broke it. It looks like it was fixed as of the build on 2016-09-21 but so far I can't find anything telling me what the actual solution was; just codeworkx asking for a log to diagnose the problem the day before. Maybe someone needs to ask him what changed??

Again with Lineage 14 unofficial builds list Video Recording as an issue. kessaras apparently developed a temporary fix but the thread he referenced has been deleted. Looks like it was fixed last May. It's Lineage anyway, so who knows if it would have helped for AOSCP or not... But it might be something to investigate?

Anyway, my point is that maybe whatever is causing the problem can be fixed with a custom kernel or a ROM update and we might be able to get some info out of the H811 LineageOS guys.

Otherwise no problems to report!
[G4 General] sdembiske:
I don't know where your problem is arising but I just tested 3 full 1080p HD YouTube videos in Chrome and each one played flawlessly on my H812 with the latest AOSCP N version. Although I was on rooted Lollipop to begin with, following the OP that Marshmallow was recommended, I flashed the Lollipop stock rom again and officially upgraded to MM H81220X with LG Bridge before unlocking. Before I flashed this rom, I did a Factory Wipe in TWRP plus a Format Data. I flashed my MM modem.bin file from my original stock SALT backup. I rooted with SuperSU, not Majisk and have Xposed installed. Since installing Camera FV-5 Lite and Cinema FV-5 Lite I have had no issues whatsoever with video recording or playback.

Where are you differing in any of this? It might provide a clue as to where the problem lies as I am not experiencing the issues that you are reporting with this rom, at all now.
[G4 General] vsTerminus:
How do you set the video quality when watching YouTube in chrome? I don't have the option and it looks like it's defaulting to either 360 or 480p for me.

I'm using the YouTube app and if I set quality above 480p the video framerate plummets until I reduce the quality again.

More or less the same, except I didn't format, I just wiped cache, data, and system before flashing AOSCP. H81220x bootloader stack, SuperSU (no Magisk), and Xposed v89 as well.

Camera FV-5 and Cinema FV-5 work well, yes, but they don't have a 60fps video recording option which is rather important to me.

Edit: There's definitely a problem with this ROM and the Camera2 API, and while using a camera app that can operate in legacy mode might be enough for some it feels like a workaround to me, not a solution.
[G4 General] sdembiske:
The Format Data step is specified in the ROM thread: [G4][5.3.1(O)][AOSP] A.O.S.C.P: CypherOS [OFFICIAL][TITAN] ...

You flashed the H81220X bootloader stack? I presume you're referring to the H812 UsU kernel and MM modem?

Check out this site re: 60fps video recording, may be a couple of ideas to try: https://www.quora.com/How-can-I-record-my-Android-screen-at-60fps
[G4 General] fil3s:
No issues with video playback here

RR 5.8.5 H815
[G4 General] sdembiske:
1) I used the YouTube app this time and, searched for 1080p videos. What I noticed, is the better the quality of the recording (quality of the camera/video recorder being used etc.), the better the playback quality. I noticed no drop off to the extent you're indicating with a good quality 1080p recording. I.E., Crappy recording = crappy video play.

2). Have you contacted the support on the Camera FV-5 and Cinema FV-5 web site to confirm re: 60fps video recording? Legacy camera mode works just great for me - still getting very good quality picture quality.

Not convinced the rom is at fault. Your expectations may be a little high for a custom rom - perhaps you should try the Nougat stock ... ?
[G4 General] spartan268:
For me personally I went straight from lollipop to aoscp oreo. And I used both the N modem and the original LP modem in the salt backup. Both had same results.

I think something about going to Oreo messes it up cause there's no return for several users who tried to go back down to Nougat as a resolution. I've yet to personally try using the MM modem but I think someone else reported that it makes no difference. Haven't had time to do any personal testing for a while though sadly.
[G4 General] sdembiske:
A number of H812 owners seem to have had issues develop as well going from rooted/stock Lollipop to AOSCP N or other custom roms.

With respect to the Oreo downgrade to Nougat, I haven't tried Oreo as a UsU kernel hasn't been done up yet for the 812.

Have you tried doing a Factory Wipe in TWRP plus a Format Data, before reflashing Nougat, then flashing the rom > the UsU kernel for your specific model followed by the MM modem file (or the LP modem file if the MM modem doesn't do the job)?

Failing that, you may have to consider FAQ 20b).
