I went from Nougat stock rooted right to 17.1. you need to do a data format so all of your internal stuff will be gone so make sure to do a backup before you do it and then I just flashed 17.1 and then the g apps magic I just downloaded the manager and then reinstalled it through there and it worked fine for me but that was on 17.1 I haven't tried 18 yet

Has anyone had issues with image rendering in apps after installing this?

More specifically, I have found that, e.g., the Slickdeals app (and others) won't display images or displays them garbled if using the default Open GL renderer. If i set the Open GL render to Skia the images render fine. However, then other apps (Nextdoor, for example) start suffering missing or scrambled images.

H910PR here flashed latest TWRP, flashed Oreo zip then the mk2000 kernel then magisk, everything worked perfectly (except that boot "your device can't be trusted" message is now static), I debloated my software however Magisk was downloading too slow, so I downloaded Youtube Vanced zip manually, tried to boot into TWRP to flash it except my phone factory reset instead...

I guess I have lost TWRP? I haven't lost root though but now if anything goes wrong there's no way to restore my backup, how can I flash twrp again?
[LG V20 Guides, News, & Discussion] darkknight200:
the oreo zip flashes stock recovery by design. on first bootup the oreo system needs to see there is stock recovery so it can boot to normal system.

This is how eng aboot can co-operate with the oreo firmware without any modem data problems.

Now you can get twrp back by booting your phone into fastboot mode due to having eng aboot and pushing the twrp from there.

Then you will restore twrp back.

I would suggest using the new oreo twrp posted in OP because it mounts internal storage properly in twrp.

My start up warning page is static too so no biggie as long as it boots.
[LG V20 Guides, News, & Discussion] Messaibi:
Thank you so much! I will do it once my phone finishes updating the apps
[LG V20 Guides, News, & Discussion] clsA:
You have root so as far as I know you can flash twrp with the twrp app or flashify or flashr or simply

adb reboot bootloader

it throttles down when gaming, ?
[LG V20 Guides, News, & Discussion] york824:
So I tried it multiple times because when I saw the messed-up screen when booting I assumed it was not done right so I re-rooted the phone and did it all over and over again. The last time I just happened to have to pee so I let the phone stay on for a minute longer and the phone boots. Feel so stupid and wasted a few hours doing the same thing. Guys if you see the messed-up screen after flashing the zip and the kernel, don't panic, just wait a few more seconds.
[LG V20 Guides, News, & Discussion] Huhahha:
thank you very much ! sometimes camera stop working, can fix it ???:rolleyes::rolleyes:
[LG V20 Guides, News, & Discussion] darkknight200:
Guys if you are having bugs that's because of bad flashing with nougat twrp.

Update to the Oreo twrp in the OP and flash the zip again.

I ran into these problems before too but now I have it perfectly flashed and it's running like a champ.

Also make sure to Format before each flashing.
[LG V20 Guides, News, & Discussion] cooki3monst3r77:
anyone use the newest MK2000 kernel with this??

As for flashing: I used TWRP 3.2.3 to flash, then flashed the kernel specified then let it boot. First boot is scary, but if you hang in there, it WILL boot. After boot, do an ADB reboot bootloader to get back to fastboot, then fastboot flash recovery recovery.img and everything is up and running. Good job OP!

Now off to debloat this heavy beast.... ;)
[LG V20 Guides, News, & Discussion] runningnak3d:
LOL -- so they check for stock recovery, and if it isn't there, then: "NO DATA FOR YOU!". I wonder if that was intentional.... I doubt it since they could have just as easily checked for the eng aboot and refused to allow data, or even boot.

Glad you got it figured out ;)

First post updated, H910_20h_Oreo_full_rooted is up

Seems you can dirty flash right over 20g or wipe and clean flash Rom and Kernel

TWRP will be over written but can be flashed back with the TWRP app
[LG V20 Guides, News, & Discussion] TheIronMaiden:
Is there a changelog for 20h? Does anyone know what has changed? Couldn't find one online. Presumably under the hood fixes but still....lol

yes sept security patch.

Anyone have any issues with fast charging on this rom? It seems that all the stock-ish type roms that I flash have issues with fast charging. They will for a bit, then they don't. I've checked the kernel settings to make sure that fast charge is enabled....any ideas?
[LG V20 Guides, News, & Discussion] darkknight200:
No problems here.

I'm still using the cable and charger that came with the v20 and still fast charges no problem.
[LG V20 Guides, News, & Discussion] sheik124:
I would tell you to poke around thermal-engine-8996.conf and edit a few lines, but it isn't the same anymore and it looks like gibberish when I try to edit it. Previously it was plain-text and had a few very overzealous configuration options that damn near limited you to 500 ma charging almost all the time. Any temps above 40, the screen being on, you name it, limited charging speed.

On the bright side, it looks like I didn't hhave to edit it on Oreo because I've been on v20h for a few days now and it works great!

Debloating was a bit of a PITA - I use Facebook, but I don't wwant Facebook as a bloody system app! Seriously AT&T/LG?! Some of the apps kept bringing themselves back from the dead too!!! I finally used SD Maid Pro and completely nuked Lookout, Facebook, Facebook Installer, Facebook App Manager, all of the DirecTV ****, and every other AT&T app other than myAT&T which I just froze (disabled) and Device Help, which I froze in either Ti Backup or SD Maid because Android wouldn't allow me to disable it. Caller Name ID nuked too, the only ones I think I kept too was Hot Spots, and it's also frozen. Any remaining AT&T apps I went after and made sure they had absolutely 0 permissions left. I know one of them was actively redownloading **** like DIRECTV as I was uninstalling it. Assholes. None of said de-bloating broke Wi-Fi Calling or VoLTE. Thx again OP.

Also, I don't remember where I saw it asked, but I can confirm that Oreo hasn't broken HDMI - it still works with my Microsoft Display Dock - SlimPort is DisplayPort over USB-C, and anything capable of handling that should still work.

Only real nuisance is being unable to get Bromite WebView working, but it should work once I change the package name.

And in case anyone is curious, none of my de bloating tripped Safety Net. If you somehow managed to, there's a Magisk module for editing device fingerprint that may help, here's mine from before I started cleaning up. I don't think any of it is personally identifying, but if it is, please tell me so I can edit it out

My Wifi doesn't work anymore (I came from LOS 15.1)
[LG V20 Guides, News, & Discussion] clsA:
Do you have a H910 ?

did you install the latest TWRP from 09-23-18 ?

did you format data before flashing the rom and kernel ?
[LG V20 Guides, News, & Discussion] hoanns:
1. Yes.

2. I installed the TWRP you linked in OP, it's "3.2.3-0 : 2018-08-17"

3. Yes

It should be noted that I used this fix to get Wifi working on LOS 15.1: https://xdaforums.com/showpost.php?p=70474540&postcount=12

Yes it works
[LG V20 Guides, News, & Discussion] clsA:
You hex edit your phone ?

You realize that guide is for a G5 right?

You need to flash the H915 kdz and see if can restore the partitions you edited

See the h910 root thread on flashing your phone to H915
[LG V20 Guides, News, & Discussion] hoanns:
It's written in the LOS 15.1 thread, that you should do it if the wifi doesn't work.

Anyways, I just flashed h910-10r.zip again, booted once, then went back into recovery and flashed the Oreo Zip + Kernel.

Now wifi works again. So it seems you can't go from LOS 15.1 to Oreo Stock without this step.
[LG V20 Guides, News, & Discussion] toastyp:
This zip works great! Haven't checked in on the v20 and found I wouldn't have to dump the update myself. Thanks a ton for doing the hard work for us. The dump process takes a while and is appreciated. My h910 is running 8.0 and took my all of 5 minutes to update. Great work
[LG V20 Guides, News, & Discussion] elyod:
Guys, thank you very much for getting these set up for us. I was able to smoothly flash the g version, however I am unable to download the latest zip because the download fails.

Hi all. I recently installed this rom and it's working just fine except for one thing, it's corrupted two of my MicroSD cards. My 128 GB card failed and then I replaced it with a 64 GB card that I had laying around and it corrupted it too. Has anyone else experienced this? Both are Sandisk
[LG V20 Guides, News, & Discussion] clsA:
No.. my 200gb Sandisk card is fine
[LG V20 Guides, News, & Discussion] emilyrugburn:
I have a 200gb in mine and no problems
[LG V20 Guides, News, & Discussion] 1914Macguyver:
I found an old 32 gig laying around and it works so far. I contacted SanDisk about a replacement, but with Radio Shack being kaput and no proof of purchase, I might be out of luck. But I'll try at least
[LG V20 Guides, News, & Discussion] clsA:
I had a Sandisk 64gb Ultra just die in a Nvidia Shield a few weeks ago

The funny thing is, the 64 bit card was working in my NVidia Shield with no problems. I put it in the V20 and it died. The good part is, I was able to save all my music from the 128GB card.
[LG V20 Guides, News, & Discussion] clsA:
I have a habit of taking sdcards and making a rar archive of it every couple of months

[LG V20 Guides, News, & Discussion] askermk2000:
As I understand there's a lot of "pirating" going on with sd-cards. I was reading up on the matter a while

back, and it seems it is to such an extent that you cannot be sure you got the real stuff almost no matter

where you buy it from.

Even if it's not outright fake wares, it could be the manufacturer itself who sells mislabeled or subpar cards

in some cases.

At least that is what I read, but it is not such a stretch to imagine it's true.

One thing is definitely true; if you buy from Ebay... beware

I followed the instructions from the first post. I was on SuperRom before. I am on the latest TWRP, from 9-30-18, I believe.
[LG V20 Guides, News, & Discussion] darkknight200:
Ok take battery out and then use buttons combination to get to recovery.

See if you can do get to twrp still or stock recovery.

That will tell me whether the flash was good or not.
[LG V20 Guides, News, & Discussion] MMIKKESS:
I booted into stock recovery.
[LG V20 Guides, News, & Discussion] darkknight200:
ok do factory reset with stock recovery and then see if it boots up.

It's been about six minutes or so and I'm still stuck on the LG boot logo.
[LG V20 Guides, News, & Discussion] darkknight200:
you only have stock recovery now so you cant re-flash the oreo zip with twrp again.

You wil need to downgrade to nougat and then do dirtysanata steps again for the h910 phone to get twrp back to flash oreo zip again
[LG V20 Guides, News, & Discussion] MMIKKESS:
OK. When I flash the Oreo zip should I use the 20g zip?
[LG V20 Guides, News, & Discussion] darkknight200:
Shouldn't matter. Both work but 20h is the latest September security patch.

But here are the updated steps:

Be on h910 twrp 9-30 build

Format phone if coming from nougat.

1. Flash Oreo zip in twrp.

2. Flash mk2000 Oreo kernel.

3. Flash h910 twrp 9-30 build

4. Boot up to system first time. It may reboot 3x before the att logo shows up. As long as it doesn't hang on lg logo.
[LG V20 Guides, News, & Discussion] MMIKKESS:
I'm in the process of attempting to downgrade and LGUP has my model listed an unknown and won't let me continue.
[LG V20 Guides, News, & Discussion] darkknight200:
I get that sometimes.

When u hold vol up and plug in to pc, let the phone fully boot into download mode and then launch patched lgup.

If you launch it while phone is booting to download mode, this will happen.
[LG V20 Guides, News, & Discussion] MMIKKESS:
It says download mode for awhile then the screen turns into some type of static mess. In LGUP it still says Model Unknown.

What can one expect from moving from Super Rom running N 7.0 to this? Is it possible to revert back?
[LG V20 Guides, News, & Discussion] clsA:
reverting is possible but like any major update (7--->8 or 8-->7) you would have to totally wipe the phone and start from scratch each way
[LG V20 Guides, News, & Discussion] Ciopenhauer:
But the phone doesn't need to be re-rooted, right?
[LG V20 Guides, News, & Discussion] clsA:
Most likely yes

The point is my roms here update your firmware to 20g or 20h

And going back to any 10x would mean a firmware mismatch and your phone will most likely not boot untill you fix it. Which would require going back to stock with a rom or a kdz that flash the 10x (Nougat) firmware.

Correction: The 10v firmware and rom are posted here >> https://r.tapatalk.com/shareLink?ur...share_tid=3771412&share_fid=3793&share_type=t

Can you just flash the Oreo rom from recovery and then flash TWRP recovery back from the same recovery session in TWRP without rebooting or do you neeed to boot up once into the Oreo version of the Rom with the stock recovery before putting TWRP back?

---------- Post added at 12:30 PM ---------- Previous post was at 12:27 PM ----------

Did you check the MD5 hash on the download before installing it? You apparently also need to use the Oreo-compliant newer version of TWRP to flash it. There is a link for that in the main post.
[LG V20 Guides, News, & Discussion] lgv20:
Hello, newbie here.

Recently i got a H-910 device from the internet. I already succeed unlocking and rooting then flashing its to this ROM. But 1 thing that bugging me is why this device always freezing and crashing with some screen of death (sometimes its green, purple, or pink). With code "reboot reason code 0x6d630300" sometimes i can use it full day before it crashing. but the other day it can crash 3-5 times a day. I use it very rarely, just for messaging or social media with 0 use of gaming.

Did i can fix it or i should find other phone??

It did happens to me, but rarely. After crashing sometimes the radio turned itself off then it hard to turn it on, but just wait it and change it to WCDMA preferred first then if you succedd change it to whatever you want. Oh i change it via *#*#4636#*#* menu which i cant open it on stock rom android v7.00
[LG V20 Guides, News, & Discussion] clsA:
Sounds like your motherboard is going out .. you can buy it or another device

You may want to try and get a refund if someone sold you a broken phone
[LG V20 Guides, News, & Discussion] lgv20:
Dank it really?? is that the problem?? It sucks. I just got it recently and the mobo gone bad.

I thought it was the ROM. Because before i update it to this ROM it never gave me this kind of error screen. But if i use that ROM i cant use the mobile data because i cant open the *#*#4636#*#* menu.
[LG V20 Guides, News, & Discussion] clsA:
Yes we have 4 - V20 in the family and none of them crash or freeze like you described
[LG V20 Guides, News, & Discussion] partyman66:
Check the md5 hash on your TWRP recovery installer and the ROM you installed. Corruption in either of those could have caused an incorrct flash with buggy behaviour. Try removing your SD card too (if you have one).. My phone doesn't work that great with mine in and crashes every few days and doesn't crash with the card out, but the same card works just fine in other devices.
[LG V20 Guides, News, & Discussion] princedede:
No. Mine do crash like that too. Started after i installed this rom. I think flashing the new recovery as mentioned on the first page can solve it. Flash rom. -- flash recovery -- use the recovery to flash the rom -- then flash the recovery again. It will stop.
[LG V20 Guides, News, & Discussion] lgv20:
Can you please explain it to me in newbie language how to check md5 and etc.

Finally someone with the same problem. I notice that this crash always occur when I open Facebook so I clean Facebook's cache, debloat the facebook vendor app through debloater, even though the apps itself isn't gone but I'm crash free for 12 hours already.
[LG V20 Guides, News, & Discussion] clsA:
The correct steps would be

Download new TWRP and put on SD card

Boot to your old TWRP recovery

Flash the new TWRP, reboot recovery

Format Data, flash V20h rom

Reboot bootloader flash new TWRP

Google MD5 checker, download the app

Open app check MD5 of your downloaded rom.zip and compare it to the AFH number

I hope that's all your problem is.

My phones were all flashed with the old TWRP from the root guide and worked fine.

I also took the OTA on my phones and all the firmware was updated.

Unfortunately I can't make a full rom that flashed everything or you would have a clone of my phone and your IMEI could be lost
