[H910][Oreo][Stock][Rooted] AT&T LG V20 Stock Oreo rooted flashable zip
- Thread starter clsA
- Start date
good night all. I installed this rom into my h-910 maybe a year ago and it worked fine until i installed an update to magisk that threw a soft-brick (showed a lg crash screen). After reading some messages online, I went ahead and flashed the rom again and got the phone working. after installing a new version of magisk, the soft-brick came back. I one again reflashed the rom and since I didnt add anything to the phone, no loss for the second flash.
after flashing the phone and installing a stable magisk, i started to add my info back to the phone. I started noticing that some apps on my phone flicker black and white whenever i open them. not the entire app, just parts of it like the top of the app etc. it happens with a handful of apps and i notice doesnt really affect me using them.
recently, i noticed that the usb connection menu pops up and defaults to charging another device aka use your phone as a power bank. I dont know if its related. the LG theme app seems to crash when i am downloading a theme.
does anyone have any idea whats going on with my phone? if i need to get a new phone or flash the rom again? thanks
also, whats does the mk kernel do?

The rooted rom H910_20h_Oreo_full_rooted.zip includes all the files of the stock romHi, what if I wanna flash the H91020H stock ? Can you please provide that ?
all you have to do is open the zip in winrar / 7zip
rename the current aboot to aboot.rooted
and boot to boot.rooted
and rename the 2 changed files they will likely be named aboot-copy to aboot
and v20h_stock_boot.img to boot
save the zip and flash it you now have stock 20H

No I have no idea what the last security patch does and no I have no intention of making another rom for this device

I'm having the same issue... Won't even boot into TWRP. Can I flash the Full nandroid backup I have from an external SD card with no computer?
Did you ever solve this? Can I flash my TWRP backup from an SD card without a computer? H910 with same issue
If you can still boot to TWRP you can flash the rom again or flash the backup
If you have lost TWRP you have to start at the beginning and re install the eng Aboot with dirty santa
the mistake here is flashing magisk on the rooted rom
all you need is magisk manager the boot.img is already patched
I never used Lineage on this device so I don't know if it works on oreo firmware or not ...sorryok thx

Thank you very much for helping me out! So just follow the rooting method like normal and all should be fine? Can I just restore my TWRP nandroid backup one I get it to boot too recovery, or better to just start fresh like I haven't rooted it at all yet?
Update... I started entire dirtysanta method over. After the kdz flash my phone was stuck in a bootloop on the LG logo, but no more kernel crash. The only way I got it to boot to the system was to pull the battery for a few minutes and plug the phone in after reinserting the battery and it finally worked. Now rooted and running Lineage OS 18.1 Unofficial. I did a clean flash right from the nougat ROM to it, and so far everything works fine. Camera is a little slow, but I don't use it much. Thank you @clsA for helping me out and everyone else who posted problems for me to read through. I hope this helps someone else out!

If you boot up into the system and there is static on your screen, then you have to flash the kernel

21Good Morning
New: Well AT&T updated us to Sept Security patch
here's the new Stock rooted rom > H910_20h_Oreo_full_rooted.zip > https://www.androidfilehost.com/?fid=1322778262904015326
Tested by @darkknight200
After @NotYetADev posted his VS995 rooted Oreo We decided to give it a try on the H910.
It's not perfect but it does work. You'll need to Format Data and flash the H910_20g_Oreo_full_rooted.zip + the Newest - H910_mk2000 kernel from recovery-twrp-h910-2018-10-18.img
Your phone will be wiped and updated to Stock rooted Oreo so backup your phone first!
If you have never rooted your H910 you'll need to use the guide here first > https://forum.xda-developers.com/v20/how-to/root-h910-v10m-t3664500
Note: when you get where you would flash 10r just use my rom instead. Don't forget to flash the kernel after the rom
Note2: Flash TWRP again before you reboot (Install / Install Image / recovery-twrp-h910-2018-10-18.img to Recovery
It's also recommended to use the new TWRP for Oreo found here > https://forum.xda-developers.com/v20/development/recovery-twrp-3-2-1-0-t3720239
Note: you'll have to flash TWRP back to the phone after flashing the rom and kernel because it installs stock recovery.
If you have any problems getting DATA on any sim other than AT&T check this post to fix your APN > https://forum.xda-developers.com/showpost.php?p=79619740&postcount=244
Thanks @StrikerTheHedgefox
After your phone is setup be sure and install the Magisk apk
Hide unlocked Bootloader warning boot screen by 4shared < This removes the ugly pink and black screen on reboot. I tested it and it works great
Huge thanks go to @darkknight200 and @askermk2000 for the Idea and the kernel.3
Hey, saw that this wasn't answered yet. Here is how I flashed both v20g and v20h. I did exactly what you're asking about. I flashed Oreo, then re-flashed the correct Oreo version of TWRP from the same recovery session. It worked both times. Obviously when I went from v20g to h, I did not fully wipe, I just dirty flashed right over it. There's no reason you can't just flash v20h directly, at least I don't think so; it should be a full image and not a differential update. These instructions will assume you're going from anything Nougat based to Oreo. You have to install the Oreo version of TWRP as your first step, and then reboot (from within TWRP) into recovery again. Don't try flashing Oreo using the older versions of TWRP. These instructions assume you're already on the proper version of TWRP!
- I made a full nandroid backup. I chose system, not system image and data, not the beta option that includes media. I usually just copy /sdcard over to /external-sd and rename it to /external-sd/.sdcard
- I went into the Wipe menu, and completely wiped "system" and then also chose the option to wipe "data" without wiping /data/media. Don't remember if it matter or not. Pretty sure it didn't, and my "internal SD card" was wiped. That's why I copied the entire thing in Step 1
- Flashed v20h ZIP
- Flashed mk2000 ZIP
- Flashed Magisk 17.1 ZIP - I've been informed this step is superfluous since mk2k is already patched for Magisk, but it didinstall Magisk Manager for me, so, do what you want.
- Flashed TWRP Image
- Went one step further and did all of my debloating before first boot! I've added two screenshots at the bottom to show what I copied off to the SD card and then completely deleted from /system/ - Wi-Fi Calling still works (AT&T customer)
- Wipe cache and dalvik
- "Fix Contents" (because you've been using TWRP to manually delete things in /system/)
- "Reboot to System"
It powered up, went straight to the AT&T logo (when I went from v20g to v20h - when I initially installed v20g, it rebooted three times before I saw the AT&T logo) re-did all the odex / oat / Dalvik stuff ("Upgrading Android" screen) then the LG theme app undid all of my substratum overlays and restarted System UI. Which was nice, because normally when you forget them running before you update, you get stuck in a force close loop.
What I deleted from /system/priv-apps/
What I deleted from /system/vendor/app/
SafetyNet a-OK :good:
You can probably get away with de-bloating more. I saw no need to; these were the most annoying, persistent, and/or resource intensive pieces of bloat aboard. Too lazy to check the screenshots, not sure if I trashed YouTube too initially, but I ended up deleting it from wherever it was and then also unlinking it from the Play Store because I use the Vanced Magisk module and I like to hit "Update All" without worrying about it disappearing.
Good luck!3I 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
Code:lge/elsa_att_us/elsa:8.0.0/OPR1.170623.032/181871124f959:user/release-keys3LOL -- 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

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
