hi folks!
I am pretty confused now. I am looking to get the V20 H990DS, but i am more confused now after reading here. My questions:
1. Is Bootloader unlock possible?
2. Can i install TWRP?
3. Can i root?
4. There is LOS official i know, but is the problem with 2. screen now fixed / going to be fixed?
Seems so good of a device, but i am insecure about it now after reading here. My old Mi4/Cancro is one of the best supported phones out there, so i dont expect it to be the same with V20, but i need working LOS with Root and working 2. screen (or the outlook on it working in the future) to be confident in buying it.
I hope you forgive me my nood questions,
Greetings
With sadly no replys, let me add what i know now:
1. + 2. + 3. Still no easy way in sight AFAIK. EDIT: To be clear: There IS a way, Dirty Santa, but the instructions are somewhat too complicated to be confident with trying. Have had rooted Phones with custom ROMs since over 5 years and never again a stock device, but i dont dare it. The 300€ i payed are much to much to have spend it on a bricked device. Will try to find more dirty Santa noob friendly explanations and post them here. EDIT2: For those who DO dare it, here the thread: https://forum.xda-developers.com/v20/development/dirtysanta-h990-t3624296
4. Second screen still a problem, nothing new heard for quite a long time.
Anyone with knowledge to add or correct, please help! Stock ROM is not as bad as i thought, but without Root, Android is not fully usable for me.
thank you pro for this thread
very useful for me.

i dont get about your complain. you said already using phone with root for 5 years so i guess you've been here on xda for a while. if you really want a phone which support custom rom go with phone which support unlock bootloader like HTC, Oneplus, or even xiaomy. its not that hard finding them on XDA. 300euro for briked devices? well, if you read v20 section carefully you knew most people here bought this devices for the camera, audio, and other things like removable battery, etc. i never found someone who bricked their devices while rooting here, even if they do we already had flasher tools like LG up which already tested fully working by some members. and whats the problem with second screen? its working for whatever it made for. are you expecting to watch movie on those 2.1 inch display? i had lg v20 h990ds rooted with magisk and had no problem so far. bought some apps like grenify and titanium backup for debloated and my phone rocking solid for abouth 2 month. if you cant wait for LOS just bought lenovo zuk2 or oneplus 3t on the same price range.
No problem doing 1+2+3 with DirtySanta exploit/procedure. It's not as complicated or dangerous as it might seem from the instructions. I thought I had soft-bricked my phone twice after rebooting normally with the old kernel instead of straight to TWRP to update the kernel first, but it was easy to re-flash the 10d factory firmware file I had and start over again without any issues both times.
Basic summary of procedure:
1. Flash factory firmware version earlier than 31 December 2016 (only needed if installed firmware version is after 1 January 2017).
2. Do DirtySanta exploit to unlock bootloader and install TWRP and root.
3. Use kdzwriter to update phone's system/modem/cust partitions to latest firmware version without overwriting unlocked bootloader/TWRP, reinstall root (SuperSU or Magisk) from TWRP.
4. Disable automatic OTA updates so that any future firmwares won't automatically install and overwrite bootloader/recovery and remove root and set ARB 1. If that ever happens then TWRP/root will probably be gone forever.
provided you follow the instructions carefully, it's safe to root with DirtySanta.

Using the steps on #3, would it be safe to say that we can update the device to oreo and still keep root?

No, right now if you update you'll lose root as the engineering aboot isn't compatible with Oreo and you have possibly non working data, invalid sim issues etc

Too bad. Your earlier post actually got me excited. Hehe. Anyway, hopefully someones starts working on rooting the oreo firmware.
The short answer? @Stele88
Yes. To all of it.
The long answer starts with the Dirty Santa root process. Believe me, I was daunted by it as well, but as long as you follow it (or the noob version of the guide you can find by searching around the same section the original guide is in) and take your time, you'll be okay. It's what I did and I'm now where I am today.
I'll address a couple things since I have the same device as you. If you want to get your device working properly on LineageOS/ResurrectionRemix (LOS with more customisation) then it's a long process.
1. Start by following the bootloader unlock process for Dirty Santa. Depending on what firmware your device gets shipped with, you may need to downgrade to (in the case of the H990DS) the v10c firmware. Once done, then you can Dirty Santa the bootloader and get it unlocked.
2. Once that's done and you're rooted with the initial TWRP from the thread installed, you'll want to look into KDZWriter. It's a program by the same emdroidle who did the Dirty Santa process for us that allows you to update your STOCK system software to newer versions and keep root. You can use it for example with the H990DS firmware KDZ files and go from rooted 10c -> rooted 10f -> rooted 10xx -> etc. until you're on the latest available 7.0 KDZ for the H990DS. This will be the longest part of your process, but it ensures that everything is up to date before going to AOSP/Lineage/Resurrection, specifically the modem partition. I recommend using the TWN region of firmwares if you're just going to convert to a custom ROM anyway, but any region will work fine (the only real difference is that, for example, the Australia region of firmwares comes with more bloat than the TWN region).
2b. You can also use KDZWriter from an updated TWRP you can get in the thread by Phoenix591, his latest TWRP versions have KDZWriter built-in so you don't have to run it off the computer, you can do it all with the kdz files in recovery.
3. Yes, you can root using the Dirty Santa method on v10c kdz firmware. I recommend Magisk for root over SuperSU.
4. There's no official LineageOS that is as up to date as the unofficial ones, and there's no official ones with second screen enabled full stop. That being said, the unoffcial LineageOS 15.1 by x86cpu has been my rock solid daily driver for about 2 months now and I've never had any issues that stop me from using it. The same can be said for ResurrectionRemix 6.2 by Blaises. To use either of these, you will need the updated TWRP from Phoenix591.
4. Second-screen enabled builds of LineageOS and ResurrectionRemix do exist, and in this case ResurrectionRemix is (as of this post) more up-to-date than the LineageOS 15.1 second screen version. If you find yourself needing additional features that aren't in the stock kernels for those ROMs (such as KCAL configuration to help with burn in, among other things), then I maintain the second-screen version of the Gamma Kernel by Omar-Avelar. People are successfully using this with second-screen ROMs and have full functionality. You can purchase the app BoredSigns from the play-store to add additional functions to the second-screen.
As I said at the start, it is a long process, but a very worthwhile one. The jump from stock to custom-ROMs is absolutely incredible. Again, in short, yes. You can get everything you want.
Just do your searching around the forums for the processes I outlined above, ask any questions you have, pre-download your kdz firmwares from HERE and any software you need, and just take your time. It's maybe a couple hours to get setup with a rooted stock system that's up-to-date, and maybe another hour or so to go from stock to Lineage/Resurrection.
P.S: If all goes well with the Dirty Santa process, but you get screen distortion after rebooting when flashing the TWRP from Dirty Santa, just pull the battery instead of rebooting.
Good luck, good searching, and remember to not be afraid to ask questions in the relevant threads.

It's highly doubtful this will happen, but one can hope. Right now the best way to get Oreo is through a custom ROM, purely because of how security is implemented by LG in the stock Oreo ROMs.

Actually it is possible runningnak3d has already said awhile ago he has a process to root stock oreo he's just not releasing it yet so LG can't patch it before the Oreo roll out is complete

Hi. I've never really liked the Android version in my Lenovo but I am now facing an annoying issue with Play Store downloads getting stuck and delayed and going to have to reinstall.
At this point I am ready for a root and changing the ROM but I am rather lost in what android distribution are working and tested at the moment as after reading for a while there are some which are only for the Win version. I also see some references to X90L on threads about rooting and installing twrp but I am assumming these would work the same on my F version.
So the question is, what updated current ROMs are working fine and are worth (better than the official one) after root and TWRP on the Android version?
Also, once unlocked and changed bootloader, where can you get the official ones again?
Thanks for any help.
"Also, once unlocked and changed bootloader, where can you get the official ones again?"
You don't need it if you flash YB via Intel Flash Tool with oryginal rom.
Hi, guys, i need some serious help. I have run into trouble.
I have LG v20 and lately, the battery was going very bad giving me SOT of around 3hrs. I searched online and found that a recent Google play services update is messing with phone batteries for a lot of phones and only possible solution at this moment is so to opt for beta Google play services, which i did and it became a disaster. I am now getting SOT of 1hr max and battery goes down quickly. I opted out of beta play services too.
I have never ever done custom rom installation, ever but this recent issue is making me think of doing it now. I have never unlocked bootloader and rest onward procedure. I have been reading the xda but i seem to find only one or two roms for my phone model.
Guys, can you please help me through this? I found some posts regarding the procedure, please let me know if they are the right ones.
1. Unlock Bootloader
2. Rest of steps
Please guide me with the step by step instructions. I am asking this because on many ROM description about the things which can go wrong and they are more than the things that will go right. This scares me.
I found only this rom for my model.

Additional info: I have a Korean LG V20 f800k with android nougat 7.0 and software version f800k10e. I installed oreo via LG UP + Uppercut 6months back and had very horrible battery life just as now, so i reverted back to nougat. I am suspecting that the flashing process didn't go well.
Hello LG fans,
There is an old thread with a similar title, but since it is inactive I started this one. For certain reasons I got this G4 phone only few days ago. The model number on the box and under-battery tag as well as in settings showed F500 (just F500 without any suffix S, L, or K). It came with Android 5.1, and everything was working well. Online search showed that F500X phones can be officially updated to Nougat 7.0, but the phone OTA update said no update was available.
As per LG website, I installed LG Bridge to get the updates. It identified the phone as F500K and found two updates. First it installed 6.0 Marshmallow and then 7.0 Nougat software version F500K30c. Also the model no changed to F500K in settings. I think this probably means it is is a refurbished phone
The Installation was successful, but it installed a Korea Telecom version with some Korean stuff. I uninstalled or disabled all the Korean bloat I could without root, but there are still a few things remaining, and some Korean language here and there.
In general, I’m quite satisfied with the phone. The only thing I wish to get rid of is the KT Wifi manager app which is all in Korean, and I don’t know what it does or which settings to select. It is a system app, and I can’t uninstall or disable it, but my wifi and data networks seem to be working fine, so no complaints. I’ve seen several people here and elsewhere complaining about network issues, boot loops and bricks, but so far I haven’t experienced any. I hope it stays this way :fingers-crossed:
I was wondering about the other variants F500S and F500L, do they also have Korean bloat and is it more or less than F500K? I have read somewhere that these three firmware variants can be interchangeably installed. Is this the case, and if so, is it advisable to install another variant? I have been reading about this phone, but this is my first time to use an LG phones, and I have no experience with their software and tools, so any help, ideas or suggestions will be highly appreciated.
Thanks

You could
downgrade to MM,
backup with SALT (CRUCIAL important),
unlock by UsU ,
extract with SALT: system ,modem and boot partitions from a f500 kdz,
root and debloat or (if you like to) install a custom ROM
Check the UsU and SALT threads (you can find both in my signature)

Thank you @steadfasterX for your reply,
It's quite an honor the Guru himself was the first to reply to my post. I have seen many of your posts and replies in the forum before, and now looked at some of the stuff in your signature. Pretty impressive work. I definitely need to spend some time learning about them particularly SALT and FWUL, as I have also started learning and using Linux lately. How come FWUL is not shown on distrowatch?
For the time being, I was thinking to stick to stock Nougat 7.0 as it's a fairly recent OS, and the phone is fine even with the remaining little Korean stuff. My main dissatisfaction really is with the mysterious kt wifi manager app which is all in Korean and has some settings which I don't know what they are. If just replacing the current Nougat 7.0 with another variant S or L is actually possible, and these variants don't have a similar app, this would be great.
I have been searching for information about these S/L/K firmware variant differences but couldn't find much. I hope other S & L phone owners could tell us about their phones. The only thing I could find so far is that each is for a different carrier in Korea, and that they can be interchangeably installed as per a Reddit post. I don't know how reliable this information is!
From a purely technical perspective for G4 F500 , is it possible to flash another F500 variant using LGUP, or is this something that shouldn't be done? I have seen many people getting in trouble for flashing wrong firmware. If this is safe to do, do I need to do any preparation work like downgrading to MM first, and should this be done as an upgrade or a refurbish? For what it's worth, my ARB value is 0.
Thanks

Hi Sfx,
1. to downgrade to MM... use uppercut, right? I'm using latest 20u for F500l is OK for UsU?
2. after backing up with SALT, can I revert back anytime after unlock and with new custom ROM?
3. after rooting, do I install twrp and load custom ROM? and can I extract 30b Nougat's modem from KDZ to use with the custom ROM?
thanks so much in advance for answering...:angel:

ok so one thing first. the most important one: Ensure you keep your ARB at 0. This is crucial important. So never ever flash anything (including QFIL restore files!!!) where you are not 10000% sure it wouldn't increase your ARB.
If you are about to flash a KDZ then check that file with SALT first (simply press extract and it will display the ARB). If you flash anything else.. well ensure that the files offered have that information listed and hope and pray its not wrong (e.g. there are QFIL files around which are labeled for a ARB 0 model but contain ARB2 files..). Never heard about a wrong labeled KDZ file but who knows.
The second important thing is (maybe its even the first): before doing anything, do a full backup with SALT (basic is fine) and (!!) move that to a secure place! (I saw so many ppl who lost their backup through several ways).
So when going on through the UsU process you will have 2 SALT backups: the one before downgrading to MM and another one after you downgraded to MM (tbh the more important one). If you can keep them both.
so about flashing other variants: yes it IS technically possible to even flash e.g. h815 ROMs to a F500 and so converting it that way! but never try that with h811 KDZs or others..
anyways yea you could flash other F500 variants without fear (just carrier bloat is different) as long as you follow the above advises.

1. I dunno the latest MM F500 version but "20u" sounds good. Can't help in the downgrade process but there are plenty of guides here in the G4 forums.
2. dunno that you mean here.. but if you wanna know if you can stay on STOCK after UsU'ing yea sure. flashing UsU does not require to go for a custom ROM. It just gives you the freedom to do so.
3. if you follow the UsU guide you will have TWRP already and that's the place where you install a custom ROM if you like. Sure extract the 30b modem and flash it in fastboot should work fine (after UsU).

if you would flash h811 on yours you will increase your ARB so do NOT flash that.
Use a h815 based ROM even when SALT compat shows different. your partition layout is somehow weird..
for non-UsU ROMs flash the f500(!!) baseband package once

hey there,
just a quick recap:
The phone is still on Android 7.1.1, I"ve got a script with ADB from 7to Forum through 4pda.to, got the custom TWRP working, but after getting root through flashing magisk, it got stuck on boot. After I got the official 7.1.1 zip, it is back on official recovery and I gave up... (Link to 4pda, which I got my inital files from - it is a link to google translate, so you could read, what it is all about
The forum here on xda-developers for Nokia 5 is really messed up and there is no real guide or any help which could help me out, I don"t know any valid source of official ROMs, there are no tools - nothing.
I planned to get on Android 9 with ROOT through MAGISK, so I"ve got a unlocked bootloader and wanted just update to Android 9, so I could install MAGISK through TWRP.
but none of that worked, I got only the unlocked Bootloader....
maybe someone could please help, I just don"t know where to start now - I have some knowledge about Android, because every single smartphone of mine got rooted (HTC EVO 3D, SAMSUNG S5, HTC MI8), as I love AdAway and Viper4Android, but this phone for a family member got me started..... This phone is brand new, never used, got it from the grandmother of my girlfriend, wanted to get it to work and give it to someone else in need of a smartphone, but I got stuck...
Thanks it advance
I've managed to update it to pie, with some obscure errors, but it works flawlessly, but I'm on 6.12 now, want to update it to 6.19, but it doesn't work through the recovery, but I'm on it.
Maybe I will write a little tutorial after all, for someone, who has also those problems like me - it is getting harder and harder to get things done on older devices...
