[LG V20 Guides, News, & Discussion] Jesus is God Almighty:
I will try this guide, he does not seem to try to install TWRP in it, which hopefully will work, that would be nice! Taking hours and hours to get to specific points, I'm just updating the version 7 to have a more updated version as a backup, although I guess it should not matter, but there seems to be a good amount of bugs in the oldest version 7 that I have:

Congrats, now you have a rooted, twrp phone. Now onto flashing oreo with root

2. file needed: TWRP 3.2.3-2 for US996 (can be found here), oreo mk2000 beta(the most up to date) kernel for F800L/s/k, lastest magisk or su zip file, oreo kdz - the latest one 2018-12-13 *I have the F800K version, so search for that if you have another phone L S K* and SD card. 3. copy all these file to sd card. 4. connect your phone to pc, open patched lg up it should detect your variant, select kdz directory, select PARTITION DL and flash kdz with partition dl mode, uncheck recovery, recoverybak, aboot, abootbak

5. wait for it to finish!

*He seems to not think I need to do anything, but just go into recovery... Like no reflash of it or anything, I hope that is true. But we will see... Partition DL as far as I can understand don't override those recovery stuff, so why should it not work? Dunno... I will try and hope for the best, this seem to be my hiccup for now*

6. boot to recovery by hold volume down + press twice the home button the screen gonna show factory reset, select yes twice then it gonna boot to recovery. 7. you might need to repeat all those step twice but > format data > flash Magisk/SU, reboot recovery then format and flash mk2000 kernel then flash root Magisk/SU again to make it work. 8. clean dalvik cache for safety, and reboot system. 9. your phone gonna booting up, if it pass through all LG logo (may take some time, be patient), you are done, if the LG logo keep showing for too long, then you may try boot recovery and repeat all those step.
[LG V20 Guides, News, & Discussion] Jesus is God Almighty:
It seems the F800K Oldest version which does not go beyond 2017 is December 1 2016. They also seem to have fixed the Camera in this version, so that is good. And the Memory issue is not there either. So at least 2 bugs fixed and most likely a lot of others. Just nice to not have those at hand.

Sadly I flip away to quick but I think the next update it is now downloading is 2017 Feb, which most likely will have the security so one cannot root.

So I should stop at this point.

The Newest version A8 F800K that one can download, has one update back to being fully updated. Not a biggie overall, don't care much for the security anyway as long as it works. It's outdated anyway, whatever I do :P

As long as I can get it working smoothly, then I am happy, with root and all! That would be my goal. If not I will just install it unrooted and use it as is. But I really would like to have it rooted. Will most likely also help me transfer programs from one phone to another future one that I am still awaiting to get.
[LG V20 Guides, News, & Discussion] Jesus is God Almighty:
No this update is from 2016 12 20... This should be all good, I will install it. And move forward, just amazing how long it takes to update things :/

Anyway, hopefully everything will be fixed without issues and then I can make a backup with less bugs from the beginning at least! :)

Hmmm... Yup takes a long time to download and update, as it takes one after another. hours and hours to do it really. Kinda wasteful if I can get the A8 working but hey... step by step getting closer to the goal.

Still have lots of videos and reading of stuff to do... Digging around and all that.

Just weird that TWRP would effect the system speed, I think... I wonder what that is about, might need to retest it to see if it continues with that. Of cause A8 might work differently overall with the speed, and who knows if there is more kernels and all that.
[LG V20 Guides, News, & Discussion] Jesus is God Almighty:
Whats the no-verity-opt-encrypt file about? Did not seem to see anything on that?
[LG V20 Guides, News, & Discussion] Jesus is God Almighty:
Okay... This update is 2017 Jan 10 so... I think I will reset the mobile now with the version I have from before Jan and go from there so I don't have the update annoying me. Although need to set things up again... But whatever. Erasing now. At least the updates absolutely made the phone better from the first. Will be interesting to see if I can root TWRP it and Root it now. And surely make a backup out of it.

So far so good :) Some more days, and some more work and it should be Rooted with A8 I hope.... I hope.... At least others have done it, I should be able to figure it out as well.

So now it starts from the beginning with the updates

So far so good :P

Security patch level December 1 2016.

Against I don't dare try to install the next update as it is from 2017, but if one wanted just to stay on Android 7 with root I guess one could try it out and see how far one can go before it breaks. At least this updated version of 7 seems to be pretty good overall.
[LG V20 Guides, News, & Discussion] Jesus is God Almighty:
After 4 days of work, study, testing and seeking I have a Rooted Android 8...

And it seems to be running smoothly and stable, as far as I can see.

What a maniac experience.

Still of cause I have things that I would like to test out, but overall... I have something that seems to work now as I wanted it, as my goal.

I should be able to restore all my apps from my old unrooted LG V20 Hongkong to this rooted phone and from there, when my main phone sometime, hopefully arrives from Germany, I can move them over without needing any google as they have a version without it which would be nice. To just get away from the Tyranny of google to the best of my ability.

Anyway... Still waiting for the phone, and I have no idea when it comes around. But at least I have a new V20 that can serve as a replacement of my broken V20. So many things have broken on it, yet... it still runs but it is ticking for sure.
[LG V20 Guides, News, & Discussion] Jesus is God Almighty:
Okay, I sorted out the issue I had with the Encryption, although not sure how I did it. I did 3 things. I have to further test what worked to figure it out.
[LG V20 Guides, News, & Discussion] Jesus is God Almighty:
So after toying around and fixing this and that, I can now say I have a rooted Android Stock H990N Hongkong model - which seems to be stable, although I have no idea if everything works or not... or if it will continue to be stable. But it looks pretty good to say the least. Thought it might work with A8 even if it broke on A7 ;)

Hack the planet... or something...
[LG V20 Guides, News, & Discussion] Jesus is God Almighty:
Well, lets just check if the mobile connection works with a sim card.... Overall, I am not going to use this phone much anymore, beside maybe as a tool or mp3 player. Really it seems to run pretty smooth after being rooted, without much issues really. Looks good, although.... Waiting for connection here.... :P

Who knows that might not work. Seems like the network does not work, I guess it could be the foreign kernel installed for the LG F800K or something, dunno - but overall, the mobile seems stable and smooth.

I could look further into this, and try some other kernels... but... well, enough for now.

I don't know how far you guys got on it, but this is my written testimony on the LG-H990N rooting and jailbreaking into freedom! So free so you don't have any calls bugging you :P Ha ha ha
[LG V20 Guides, News, & Discussion] ElMudshark:
Before I start I need to know how to find out if I have Google's security patch of January 2017 or later.

It's an LG v20 vs99520c

Security software = MDF v2.0 v4

Android 8.0.0

Androiod security patch 10 October 2018

Kernel v 3.18.71 -perf+
[LG V20 Guides, News, & Discussion] C D:
Google's security patch referred to by the OP is the same as the Android security patch date. Nowadays, the chances of having a V20 that doesn't need to be downgraded for this procedure are very low. And any phone on Android 8.0 has a patch date from 2018, so they all have to be downgraded for this.

Bro, were you able to get Lineage running on your H990N? I've been able to convert an H915 to H910 by flashing the H910 stock firmware (kdz) without any issues for months now. I'm considering converting the H990N to H990DS through the same process.

Can someone chime in if this is the right way to get Lineage OS 18.1?

This thread helped me on my mission to convert my H915 phone into an H910 to get VoLTE working on AT&T's network in the U.S.. AT&T a wireless carrier that is banning all V20 except for H910, so I went H915 -> US996 -> H910 and I'd say life is now good, except they know my IMEI was once a H915 and refuse to ever look at the current device reporting from that IMEI, so I'm still kicked off their network, in the long run. But thanks for helping me complete my adventure.

in terminal emulator on the android device:

verify ”Context = untrusted_app” in the output

then

cd /storage/emulated/0

then

applypatch /system/bin/atd dirtysanta

there will be output about applying the patch. wait for it to finish then proceed with the remaining instructions. Good luck

Boss sorry if someone has already asked this question

I have an lg v20 h910v10jPR for a Puerto Rican carrier Claro and the ARB is 0

will this method work for me??

all my efforts to get a very simple and clear answer have proved futile I hope this honestly

I recently got the phone and realised I can't unlock the bootloader since LG's developer website has been shut down.

it has a lot of features missing and it throttles badly even when I played basic games

to cut it short will this method work for me?.
[LG V20 Guides, News, & Discussion] baugen55:
Great! I tried the 2 other methods but got syntax errors at elsa prompt in Windows. Not sure why, I did follow one of them to the point of installing 915e but the security patch was from 2016. This just worked from the rootable 915 rom.
[LG V20 Guides, News, & Discussion] baugen55:
Yes this should work. I don't know if your version is rootable but you will soon find out, then you must install an earlier software and root from that.

Please help

I was reading this topic but I my LG is F800S. How do I unlock the bootloader

My Goals

1. Unlock the bootloader

2. Flash twrp

3. Upgrade from Android 9 to Android 11 Lineage OS 18, and eventually Android 12 when LineageOS got it :)

Please help, guide me to the topic for LG V20 F800S. I was looking in the forum I cant find it for this particular model

I appreciate your help
[LG V20 Guides, News, & Discussion] baugen55:
You must use patched LGUP to go back to an earlier firmware, in this video (below) this is explained in detail. When you have done that you connect the phone to pc and use ADB suite to run the JustRunMe.cmd script. What you have in this thread is a simpler and more automated version of the method in the video and other threads on rooting. Read the thread, watch the video and get an overview of all the steps.

Thank you baugen55 :)

I have a question.

In Android 10 on another phone I have

OEM Unlocking - Allow the bootloader to be Unlocked

On LG V20 F800S Android 9 I have

Enable OEM Unlock - Allow the device to be OEM unlocked (this option can only turn on when I set security to None (delete Pattern/PIN, fingerprints) otherwise it does not turn on

Having seen the description in Android 10 is this feature in Android 9 the same

How do I determine the booloader is Unlocked

I restarted the other phone in Recovery and I saw Recovery/FastBoot/System (3 separate lines)

Please advice how to determine the bootloader is Unlocked

Thank you

What is OEM Unlock and Why You Need It | Updato

Ever wondered what is OEM unlock and why your Android device would need to have the option enabled? Here’s a complete breakdown.

updato.com

PS Here is what I found online though I also want to hear what you can say :) (you have much more experience than me. Appreciated)
[LG V20 Guides, News, & Discussion] baugen55:
It's not unlocked until you have twrp installed.. and that will not work unless you have a rootable version of android, which is why you must downgrade. I believe that even if you get usb developer mode enabled the dirtysanta method will not work unless you downgrade first, it was blocked with security patches back in 2016 - 17
[LG V20 Guides, News, & Discussion] baugen55:
I'm afraid this info you found online is outdated. LG terminated their bootloader unlock service last year when they went out of the phone business. Therefore downgrading --> dirtysanta method is now the only option if you really want to root your phone.
[LG V20 Guides, News, & Discussion] lkstamenov:
True. The service with Unlock codes is not available

LG Developer

The official developer resources for LG products and platforms.

developer.lge.com

Then yes dirtysanta apparantly. I need to read and practise more. This method is beyond my current experience
[LG V20 Guides, News, & Discussion] jimmy crypto:
@baugen55 with regards to my v20 h910pr v10j will this method work ??
[LG V20 Guides, News, & Discussion] baugen55:
Yes, it is on the list of included models. But have a look at the YT video above, it is a very detailed presentation of the process, with a link to another thread here which is also very detailed.

I Tried it Today

the h915 rom installed properly

but after trying the dirty santa method it booted to android instead of twrp

i performed a factory reset and ended up with a green screen

any fix?
[LG V20 Guides, News, & Discussion] baugen55:
sounds like you may need this https://xdaforums.com/t/guide-unbri...res-unbrick-v20-variant-mismatch-fix.3652222/ (however I'm a beginner myself and don't know exactly what you did, but maybe you forgot that first boot after twrp install you must not let it boot by itself because bootloader will be overwritten again- ? Did dirtysanta exploit give errors?)
[LG V20 Guides, News, & Discussion] baugen55:
after installing twrp successfully the factory reset key combo should get you into twrp and you can flash supersu/magisk and custom roms. otherwise you must use patched LGUP to get back to a working rom and start over.
[LG V20 Guides, News, & Discussion] zenmode:
no need Bro, I Fixed it with LGUP, I went back to LGUP and connected the Phone in download mode and re-loaded the h915e ROM and it Booted successfully. anyways I'm not trying the root method anymore since this is the only phone I have currently. Any fatal error and a lot of things will go real south for me.

I'm not giving up on it though. I'll try it once I get a second phone

A few Benefits I got after flashing the h91510e ROM

1. Overall Signal strength is better compared to the stock h910v10jPR

2. Phone doesn't Heat too much again

3. Battery Performance has also improved
[LG V20 Guides, News, & Discussion] baugen55:
Great! Now this rom is rootable so it should be able to coexist with TWRP. That worked on my 910. But I think you are right to be careful.

I have 3 V20s all bought used, VS995, F800 and H910. Reason I want this phone is the high end audio capabilities and the ability to take out battery and SD card - and its still a high end phone in 2022. My H910 is a bit of a hopeless case as it is missing some bands needed here in Norway, so no signal. I will try a US996 rom, if that does not fix it i will get a H990 mainboard for ca $40. edit: US996 does not work at all despite posts to the effect that it can be used. It almost bricked my phone, twrp crashed and the OS did a boot loop. Got it back to 915e, finds sim but no phone signal. This is the same with stock 910 roms.

[LG V20 Guides, News, & Discussion] dextructor:
I can't vouch for the files that the OP refered, but as anything you should be as "period correct" as possible. Every driver, fastboot, the same version for achieving consistently results.

My considerations/recommendations for this include the necessary files, and everyone that followed word by word could unlock with minimal modifications to each variant.

I tested with Windows 10 and 11, using many USB cables, hubs always unlocking at the end.
[LG V20 Guides, News, & Discussion] ssurell:
Had to boot into Linux to flash boot2.img and finally booted up. Been going back and forth between Windows and Linux a lot with this one.

Previously OEM unlocked US996 that failed secure boot and relocked itself after using some Qualcomm tools. Now the original unlock.bin doesn't work.

Update: After going through this, I used LGUP to flash the 10d US996 kdz again (for the umpteenth time), toggled OEM unlock in Developer, and was finally able to flash the OE unlock.bin using fastboot. Updated to last US996 kdz firmware, flashed TWRP v3.2.3, red boot screen gone and everything back to normal. IDK

Me and the guy on page 2 have the same problem. It's the Security update from January 2018. I get the same error when i try to do it. applypatch kicks back that we have to add -c or -b or something to it and that we're not using it correctly.

I'm guessing that this is the fact that i have LS997ZVC and therefore won't be able to root the phone until someone releases a patch that works with the new security update. This really sucks because i paid my phone off in full and moved it to another carrier, but if i pull my battery out i have to factory reset my phone every time to get it to work with different sims. So I basically can't put anything long term on my phone. I wanted to flash it to a Custom Rom so i didn't have to do this anymore.
