V20 vs995 oreo question - LG V20 Questions & Answers

I seen oreo has been released on the v20 and alearted my youtube fans about the update and not take it or lose root. Since oreo is a new version of Android OS will the uppercut downgrade method still work for oreo to 13a or will it brick the phone
If it will brick the phone is there a way to downgrade to 13a or is there a root method for oreo
Thank you

can you get twrp on h91810k (may 2017) with unlocked bootloader lg v20 tmobile?

I have tmobile v20 and accidentally installed the latest update. I know It's impossible to downgrade due to antirollback. If you sucessfully were able to get back to twrp please share.
thanks

I tried to downgrade using lgup it don't work man.
It does work. It worked for me. I just got my V20 a few days ago and updated it. Then i rolled it back so I could root.
Please do some research first before posting false info. Its doable

LG H918 OTA 10P KDZ? Update:warning

HI. The LG H918 10P OTA Update.zip has started pushing out. I received it on my phone last night. Can somebody provide a link to the LG KDZ for this update? I want to get on making a stock flashable zip ASAP.
Warning Note: this new update is anti rollback V1 so if you have root DO NOT take the update or you will lose root!
Thanks in advance!
UPDATE: I sniffed the following url from LG Bridge but it's not working for me yet

I wonder if 10N was about to be rolled out then was aborted in favor of 10P. Strange since the Android version itself on both remain on the 7.0 branch. Hopefully the full fledge 10P build will emerge so devs can incorporate any fixes and what not into ROMs.
Edit: Looking at LG's kernel source distro looks like we also missed out on 10O as well as that's up right now. No kernel source as of now for 10P.

You must be new to LG. They stay on the same point release as the phone was released with with all updates. Okay only when they update to the next version of Android does the version number change.

Until you posted this I swore at least the G6 and some of their recent lower tier phones were on 7.1.1 but alas they too are on 7.0 as well. So yeah the next major push LG will do is probably to whatever Android O will be (which is 8.0 the last I heard).

you can't I've tried waiting on a 10p root I havn't tired to root yet
Is it possible to flash a rooted 10p kdz? Is there one?
I unlocked the bootloader with 10p and tried root with easyrecowvery and dirtycow. ER will not install twrp successfully and DC hangs at the logcat command.

If your bootloader is unlocked can you try this:
https://www.howtogeek.com/240047/how-to-flash-twrp-recovery-on-your-android-phone/
Earlier H918 bootloaders (10d etc) did not have the FLASH command built in if I remember correctly. Maybe LG threw us a bone and included it in this bootloader.
Let me know. If would be great news.

If you do what my previous post says make sure as soon as you get into twrp that you FORMAT data and system (you will lose all data but it will unencrypt the rom) and flash the 10p stock rom, modem, and bootloader. If you don't, you may get a boot loop. You might get one anyway, this is risky. But you already unlocked your bootloader so it's obvious you are down for a little risk lol
God's speed sir. This could be huge

What's the latest update we can use and not lose root?

I'm not well versed in this realm of rooting, but I've rooted my V20 (H918) and I'd like to update to the latest version possible and not lose root. I think it involves using some kdz file or something and flashing that, is that right? Let me know, thank you.
Wrong, you have to use this @runningnak3d tutorial to go back to root...but so far, even if you are on H91010T, you can roll back and root. ARB has not yet been implemented on this phone, so you're good to use any rooting method you see fit in this forum. Enjoy!

I think you may be responding to the wrong thread? I wasn't asking how to root, I've already rooted my phone. Also, I said I have a H918, not a H91010T.

Oops!!!! LOL! That darn 8 looked like a 0! My bad, bro! LOL. Late night!!!
You can use kdz writter to upgrade to kdz with new security updates. You will not lose root.

do not use anything kdz to flash... you will lose root! you need to flash a TWRP flashable zip to update and keep root

Thank you! That would've been atrocious. Can you point me to a guide that explains this? I'd hate to make a rookie mistake like I would've made and accidentally update the firmware past 10J.

I don't know what version of H918 you're on now, but if I'm not mistaken 10k is the last one that you can still mess up and still get root back by downgrading to an earlier version, root and then upgrade. any version after 10k will increment ARB to 1 whereby you will not be able to get root if you lose it. that said, the latest version out now is 10s and if you have root then you should also have TWRP. here's my guide for updating to the latest versions while keep root https://forum.xda-developers.com/v20/development/rom-h91810q-stock-rom-twrp-flashable-zip-t3681312. looking at this now, I haven't posted the 10s update file, which I will do now... keep in mind that if you update to 10s that if you lose TWRP you'll be fscked and stuck without root, which at this point could be permanently.
EDIT: 10s is a go! original post updated with link. also removing the older versions from Google Drive to free up space... if they're still needed, PM

Hey, I followed the instructions per your thread and successfully installed 10s and kept root! The bad news is that I did a factory reset immediately after and now it keeps bootlooping into TWRP. Any idea how to fix this? Sadly I didn't make a backup because my microsd card was too small and I didn't have the patience to wait til tomorrow and go out and buy one, really hope I didn't kick myself in the ass and brick my phone. :crying:
Edit:
I was able to find a fix by following these instructions:
"I had this happen to me after installing TWRP for the first time. It would keep rebooting to TWRP. This was after making sure I flashed SuperSU as well. Eventually in a moment of "might as well see what will happen" I rebooted then held down the power button and volume down. Got to the option if I wanted to factory reset my phone which I did which booted into TWRP. Rebooted to system from there which got me out of the TWRP Bootloop."
I also set my phone up again and can confirm that 10s is still good with root! Thanks for the guide and work, man. Much appreciated!

LG V20 T Mobile Mobile Data Not Working after Update

Hi Please help me, i upgraded my OS to Oreo, and after that, i can recieve calls and messages but when im turning on my mobile data, it doesnt work. My APN is correct, any help
Thanks
And when did T-Mobile release Oreo for the H918?
From their support site:
Software version: Android 8.0 Oreo
Phase: Manufacturer Development
T-Mobile and the device manufacturer have agreed to support a new software update. The manufacturer is working on it.

If you have a rooted phone, and you installed boot and system from one of the models that currently does have Oreo, no -- your modem isn't going to work with their rild.

Maybe he means lineage?? The lineage build is Oreo right?
Could be, but that would make diagnosing the problem much easier if he would have said Lineage
If that is the case, I hope the OP made a backup of their EFS....

Hi Brian...
I got my H918, Used your FWUL and LAFsploit.... (I think you are like a V20 rockstar...? thank gosh there's guys like you and websites like XDA to find you with!)
Got superV20 V2.1 on, I installed with
the option or the MK2000 kernel, although, I'm listed as kernel version 3.18.31. My softwaRe is 10t security patcheck level, March 1st, 2018.
In the last 2 days TMOBILE has been trying to push an Android System Update, of around 119.8 Mb to my phone.
(I don't know that it matters or is even noteworthy, but my provider is Virgin Mobile Canada, In B.C..)
It's asking for restart before installing, and I just keep closing it.
Could this be Oreo?

All the ones I've seen are for downgrading from unlocked /rooted oreo. Mine is completely stock and I haven't seen anything for that.

Reread them again. They're downgrading in order to root (mostly), not with root.
But the TLDR of those guides is LG UP, in upgrade mode, with whatever firmware (kdz).
Anyway here's a link to the vs995 thread where the guy made videos and has links to lgup and one of the old firmware that can be used to root. If you want to browse or download a different one this site is ok but slowish
