[G4 General] steadfasterX:
really its hard for me to understand what you have done when not given me all information asked for..

1. which exact KDZ do you used to flash on the sdcard ?

2. are these the SAME then the ones you have tried to flash in fastboot?

3. have you checked the ARB of the kdz you extracted?

4. next would be (if the ARB is not higher then 3) to boot to fastboot and flash the CORRECT bootloader stack of your device model but ensure the ARB is not higher then 2!

5. again IRC is much easier for these kind of support..

-
[G4 General] rezalaga:
1.Using MM KDZ

2. yes

3. Yes my device arb is 2

4. how to boot to fastboot when using sdcard?i have try to boot to fastboot but fastboot read the partition from the sdcard, not internal storage

5. what channel?
[G4 General] mwahahaa:
In trying to isolate what is responsible for my problem on h812. I have LTE connection and mobile data along with SMS. Wifi and Bluetooth work fine. The only apparent issue is I can't send or receive any calls. SIM card works fine in another device. Can this particular problem be isolated to a particular .bin file? AOSCP nougat with MM modem. The AOSCP kernel messes things up for me.
[G4 General] steadfasterX:
4 -> when u say "read" you mean you tried to "flash" ?

5 -> pls read the OP -> Support / IRC Channel

No idea what that means: "The AOSCP kernel messes things up for me".

Do you meant the

UsU

aoscp kernel? what means "messes up" ??
[G4 General] nummer:
I'm not sure, I flashed G4_ARB-0_29a_bootloader_UsU.zip once, I'm not sure if it is still around or not :confused:
[G4 General] mwahahaa:
Freezing, force closes, generally sluggish performance. The ROM operates much more smoothly without the UsU kernel.

Video recording is also broken.

Is there a ROM available to take back to stock LP unlocked? I know the SALT backup would be the best option in this case but I messed that up.

I know you must be stretched pretty thin dealing with the range of different problems with different devices. You need a full development team and a beta program!
[G4 General] steadfasterX:
if you flashed it once it is still active.
[G4 General] mwahahaa:
http://bpaste.net/show/9211565af086

Tried persistent mode, still no partition to extract.
[G4 General] steadfasterX:
I had a private beta with several users. Consider what would had happen if I would had released UsU 1 year ago?! a nightmare.. But its always one thing to test things with a few (as the risk is high) and a complete other going public..

finally... someone is able to grab a log thx!! :victory::victory::victory::victory::victory:

will be fixed in a second. ;)

EDIT: should be fixed in SALT v3.11
[G4 General] mwahahaa:
Almost, but still had an error: http://bpaste.net/show/7a15d3be5e6e
[G4 General] rezalaga:
No problem already, i have successfully recover my H810 using qfil but i change aboot and laf partition from usu and editing some line in rawprogram.xml from the recovery file, will try again to updgrade to N, hehehe, i'm sorry bro.....
[G4 General] nummer:
Alright, I think I got the idea on what to do:

- fastboot flash the partition images from my SALT backup that were listed in faq 18

- flash custom rom with gapps

- flash UsU kernel

Then theoretically everything should work?
[G4 General] steadfasterX:
Almost:

extract a MM kdz matching your device model but not having a higher ARB then 2 (SALT 3.11 will display the ARB when u extract a KDZ)

flash the files listed in FAQ 18

flash either AOSCP Nougat or STOCK v29a nougat and gapps if needed

flash the UsU kernel

(if you use it: supersu/magisk needs to be done after UsU kernel flashing ofc)

if you encounter any issues follow FAQ zzz
[G4 General] Jonotjie:
Silly question. :)

I have the G4 815-P. Would it be advisable to do this as this is my only daily driver. And I am often on standby, so calls and messaging is important.

From the Poll, I see much more 815's that have been unlocked.

I guess I'm just scared. I last Flashed when I had my LG G2 :)
[G4 General] 593cdn:
Hey man I'm trying to read up on everyone's responses on the h812 but i'm really not that experienced to understand everything everyone is saying. I thought I'd ask how's your h812 doing now, is there any problem with your phone after a few days of use on the custom rom you're using?
[G4 General] hey_joe:
Well I thought that everything is ok until some users report that video is not working which is something I haven't tested ( just did the photo-taking function ). And it turns out mine is not working as well. It gives out an error as soon as you change to video from photo. I just went back to my original MM ( but now rooted ) to have all the functionality and will come back to Nougat one day when the video function is fixed. I've been through 4 roms ( 3 from Tmobile and one from steadfasterX which is stock nougat ) and in every case every function works except for the video recording.

[G4 General] fates13:
Any other suggestions you might have for me to try on the VS986?
[G4 General] pr3dicament:
Alright so I have an issue with installing any rom made for H811 in TWRP. My GPT compatibility shows H811 in SALT. My device is an H812. Keep in mind that I got the same result with Resurrection Remix and all others that I have downloaded for the h811. There's barely any roms that are specifically made for the h812.. and Yes, I tried searching and looking in the FAQS among other places; I downloaded these roms from the Downloads section of the original post, as it said that H811 is compatible when I used SALT; according to GPT compatibility, that is. I'm guessing my search was a little too specific but I haven't seen anything addressing this. If I'm wrong, please point me in the right direction.. I'd really appreciate it. Is there any advice as to how to get around this? It gives the following when I attempt to flash the zip:

"E3004: This package is for device: g4, p1, h811, ls991_UsU; this device is h812."

Updater process ended with ERROR: 7

"Error installing zip file '/external_sd/lineage-14.1-20180102_003620-UNOFFICIAL-h811.zip' "
[G4 General] steadfasterX:
its easier to discuss things on IRC. (Read OP - Support..)

faq #13

:(
[G4 General] mwahahaa:
You have to open updater-script using winrar or similar program, change all H811 entries to H812, then save to archive. It will then install in twrp without error.
[G4 General] David X:
Thank you very much. Current rom works fine. I have backed up all in TWRP. Can you please explain that I can just go back to current rom thru restore and everything will become normal even if there are some issues during trials of H811 roms?
[G4 General] pr3dicament:
I'm not sure why I originally thought that didn't apply to this situation. Fair enough, I'll edit the script and if I have an issue furthermore I'll probably be asking more questions. Sorry about that.
[G4 General] izzle47:
Hello, i have two g4's a h810 and a vs986 and I boot into download mode and salt isn't recognizing both devices, the h810 is on h81010o kdz while the vs986 is on vs98610b kdz, what could be the issue with the devices not being recognized, I tried with a h815 and it's being recognized in Salt in download mode.
[G4 General] steadfasterX:
This is not the SALT thread sorry.
[G4 General] Jonotjie:
I decided to give it a go.

And I'm unlocked.

LG G4 815P :D
[G4 General] fates13:
Finally got it working!!! Not sure what exactly fixed it but here's what I did to get LTE and Cell Service working on VS986

1. Wipe dalvik/cache + data + system + cache

2. Format data

3. Flash MM 28A boot.img

4. Flash MM 28A modem

5. Flash MM 28A system.img

6. Reboot

7. Reset Network Settings

8. Wait for it to pick up signal and test

9. Reboot and reflash TWRP because it gets lost flashing the stock MM system.img

10. Flash supersu and whatever else

Hopefully someone can figure out Nougat on VS986 one day but I'm happy on stock rooted MM for now.

"Open Camera" app - working OK on H812 with H811 AOSCP N installed!

Reported in to work on Lineage OS 14.1 as well (not confirmed by me on the H812). Worth a try if you're experiencing issues on Lineage N, for example.

Just a short note for those experiencing issues with their video recording/playback with their current camera apps on H811 AOSCP N, Open Camera is working, so far OK ... let it settle in after a couple of reboots and clear the cache and data for the app after installing.

It's available

free

on Play Store

( https://play.google.com/store/apps/details?id=net.sourceforge.opencamera&hl=en ) and better yet, there are

no annoying ads

. Check it out if you're having issues with your current one. Has lots of option settings etc. An OK replacement.

Addendum

: My new go-to Camera/Video app(s) are Camera FV5 Lite and Cinema FV5 Lite . Much better quality/performance, IMO. Reference post # 527

Hi, first my english is very bad but I can read well!

I flash my LG G4 and install lineage-14.1-20180101_232135-UNOFFICIAL-h815.zip, but all of my phones sensors disabled!!!

I was able to restore my original nandroid backup, after which I flashed all the files recommended in FAQ #18 from the kdz I originally used to root my device. The same problem exists with calls, only its worse overall because the phone keeps freezing up and is very unresponsive to input. I even reflashed the UsU h812 LP baseband but that didn't make a difference. Any recommendations on what else would have to be done to return to the original unlocked state from a backup?

I did it all, including the wipe and I ended up where I started. The AOSCP ROM is very smooth with no sluggishness and freezing like with my original TWRP backup. The strange thing is I have a great mobile connection, LTE is working fine, as is SMS. It is just voice calls (and the lack of video recording that some others have found). I don't know if that helps in the diagnosis.

Battery drain issues on N ... ?

One of the things, in addition to Greenify and Amplify (pro/paid versions recommended) that I have installed for reducing battery drain is AppopsXposed. It is similar to the Privacy funtion in Lineage OS. It also, as with the other apps, requires Xposed to be installed (Greenify for the Xposed based features).

For a tutorial on how to use these mentioned apps, refer to ✭[GUIDE][26-07-2016]Extreme Battery Life Thread(Greenify+Amplify+Power Nap)✭

Senior member Xspeed has adopted the AppopsXposed app for Nougat: refer to post # 883 in that thread - he has provided the apk for download in his post. I have installed it in H811/H812 AOSCP N on my H812 and can confirm it is working as it should on my phone. Normal course is to turn off Keep Awake in both Google Play Services (not Play Store) and Google Services Framework and anything else you feel is causing unnecessary battery drain, if it is not required to remain awake.

Alright, I'm not sure if there's much you can do to help here, but I noticed not long after flashing UsU on another G4 device (H812) .. it was working for a little bit, I didn't do any updates or anything like that.. I noticed it just randomly rebooted into a GREEN "DemiGod Crash Handler" .. I saw some stuff about blue/purple screens but not a green one. And to be clear, yes.. I flashed my baseband. I didn't flash any other bootloader stack. I have a basic backup and a backup in TWRP but I cannot boot into TWRP without getting this green DemiGod screen. I attempted using fastboot to reflash TWRP, so I did.. it still didn't boot into TWRP. Same result if I try. If I just attempt to try and let it boot, it just sticks on the LG screen.. sort of like a boot loop. It doesn't even get past the screen that shows secure boot being off. It just turns off, turns back on. Can't even get into TWRP. Just keeps shutting off, similar to a bootloop. Anything I can do to fix this?
[G4 General] steadfasterX:
Can you take a photo of that green screen?

Yes what you describe sounds like FAQ 14.. You can try the link there and modify the boot image and TWRP to 4 cores..
[G4 General] pr3dicament:
I want to reiterate that I only get the Green demigod crash handler screen if I attempt to boot into recovery.. at that point TWRP had already been installed, things were working, installed and backed up fine.. but I have no way to access it via TWRP. For the hell of it, I tried to reflash it, and it showed the first boot TWRP screen, then I got the green demigod crash screen again. I'm pretty sure it's ****ed.. I also tried flashing the modem.bin in fastboot from the backup (yes, I can still get in to fastboot and I can still go into download mode, which is why I'm asking if it's possible to salvage this or if this just sounds more like the infamous LG bootloop--I figured I'd ask at the very least.. SteadfasterX seems pretty qualified to at least ask if it's salvagable or not)

.. I doubt this is salvagable. This phone is used.. and I think the hardware is just a flat out dud. I'm still asking what there is I could do to salvage it before attempting to return it (yes yes I know, I got it on eBay. I'm pretty sure I did nothing wrong here in the first place based on the other device I got which is still working without a problem.. same model, different seller.)

---------- Post added at 08:04 PM ---------- Previous post was at 07:59 PM ----------

Yeah I can't even get to the green screen now. Now it just freezes up. It started booting and then froze up about half-way into the boot process. It makes sense since it just RANDOMLY turned off and started giving me that issue in the first place. I'm guessing it's because I let it cool down or somethin'.. but I'm pretty sure this is screwed.. probably was defective before I even placed the order for it. I'm gonna have to request a return on eBay--it's a used phone. -_- I'd open it up but at the very least I want to see if I can get a return first. I was looking at the ILAPO guide you made, SteadfasterX... I might try letting it cool down more but I'm pretty sure this is just defective. If I get the green demigod screen, I'll take a shot of it with the working G4 that I have :P

SteadfasterX, regarding FAQ #14.. i'm looking at the links for the .TOT unbricking method, and I cannot find one under MarshMallow for the H812. I had a Marshmallow stock rom prior to being basically not able to use the phone, but since I do have access to fastboot, would it be okay to attempt to use the .tot listed for Lollipop on the unbricking page? And also, I was able to get a shot of the Green screen. My apologies if I already posted it, I can't really remember right now.. been focused on trying to at least get the phone working.. just to try, at this point..

https://imgur.com/a/rGxKf

---------- Post added at 10:44 PM ---------- Previous post was at 10:12 PM ----------

Now the phone is booting fine after letting it sit for a couple of hours turned off. I wish it had done that before so I could actually not have to worry about whether the seller would accept a return, lol.. Hopefully they don't know what UsU is. The good thing is that it works enough to where all they probably need to do is just put some thermal paste on the CPU.. I'm pretty sure it's overheating. TWRP booted fine, the OS booted fine, no freezing up, nothing.. as if nothing ever happened.. but it's definitely a sign that something is wrong hardware wise. So.. with the unbricking method you have.. could I use something not specified for the H812? I don't see anything specified for it with Marshmallow H812. if it's a CPU issue and it's just getting too hot, I'd like to at least mod it to have it only use 4 (cooler) cores for other devices I use to avoid this problem in the future, especially if I can't return this.. then it won't be dead weight. Thank you for your help in advance.
[G4 General] steadfasterX:
Ok walked through your story and I have to say it sounds 100% like the ilapo. It is not fully applied yet but that's the way it goes usually.

If you go through the link in faq 14 you should fine several ways of temporary(!) fixes..

The only real one is replacing/reparing the MB though.

Remember and read FAQ 2 before you thinking of the TOT unbrick! This way is not possible after UsU but you can achieve 100% the same using the boot image X cores guide. Just with a bit more work.

The green demigod is odd. It shows up invalid ram console and that usually means in terms of UsU: LP bootloader stack. This can be fixed by flashing a MM bootloader stack. Is it true that your bootloader is on LP?

It's a shame what LG has done on this device (and others) but on the other hand... It had made my life easy due to my several unfixable hard-hard bricks. The ilapo made it possible even if I never had any ( there is a way to let it LOOK like one though..)
[G4 General] pr3dicament:
MarshMallow boot stack.

---------- Post added at 02:36 AM ---------- Previous post was at 02:32 AM ----------

Actually, I don't know which actual bootloader stack it was on, the phone was used but nevertheless came with Marshmallow for the OS itself. I could be wrong about the boot loader stack.. but that green screen hasn't come up since I let it cool down for a few hours.. seems like the hardware is probably screwed. And like I mentioned earlier.. now everything is suddenly booting up fine and all of that. All symptoms I mentioned were all very sudden, including it suddenly working again as if it never screwed up in the first place with no fix applied at all aside from just letting it sit. It seems like failing hardware to me.

[G4 General] sdembiske:
In the downloads section in the OP, the AOSCP for Nougat. It's running very smoothly on my H812, no lags whatsoever and I'm really enjoying it. Just make sure you follow the OP instructions instructions

to the letter

(I think some of the members posting with problems have gone off script, flashed other custom roms not in the download section in the OP, forgetting to remove the 1st/assert line in the updater-script, etc). Refer to my post # 361 for some guidance and a solution to video recording/playback that has worked perfectly for me. While I installed the version noted as H811, steadfasterX has since uploaded an H812 version (it wasn't uploaded when I downloaded and installed) - so your ROM info on your phone will show H812, not H811 I believe - basically, I think exactly the same rom except for the phone name change, but I'll defer to steadfasterX on that ...

Good luck.
