Hey guys,
I think this is my first post on XDA
I have a UK H850, with TWRP and SuperSU and stock ROM. I have a very early version, something like version b.
Anyway, my reason for posting is I would like to update my firmware version because it is a year old to the latest version, or a custom ROM. I have looked around and I cannot seem to find a definitive answer on weather I can use flashfire app to successfully update and automatically reroot the device. If this does not work, what other methods can I look at? TWRP flash? Will I be able to keep my current data or will I have to restore from titanium backup?
Thanks :good:
TL;DR how the update do

Updating your firmware should be fairly easy with LGUP. (I've done it successfully several times with my UK H850.) Just find the KDZ files for your UK H850 here: https://lg-firmwares.com/lg-h850-firmwares/ If you're going to flash Nougat firmware, make sure you have the latest TWRP: twrp-3.1.1-0-h850. After flashing stock firmware you'll have a stock G5, which means no root and stock recovery. (I don't believe there is any way to retain root when flashing stock firmware.) The good news is that after flashing stock firmware your bootloader will still be unlocked, so you can flash twrp-3.1.1-0-h850 with fastboot and then reroot by flashing SU with TWRP. You have correctly deduced that retaining your data will require separate action on your part. And don't forget that if you want to remove encryption on your data you'll need to format (not wipe) the data partition in TWRP.
Good luck!

EE. The latest firmware I've flashed is H85020d_00_EEO_GB_OP_0403.kdz. I'm using the G5 in the US with a SIM card accessing the AT&T network, so I have deleted the EE bloatware that came with it. I bought it, of course, since it was a European H850 with an unlockable boootloader.

Have you successfully unlocked the bootloader on the ee variant of the h850?? If so I guess you could also flash other networks ROMs and also lineage os right?

Yes, the bootloader on the EE H850 is unlockable. I wound up with the EE H850 by chance; I was ordering a "European version" of the H850 online for the express purpose of getting one with an unlockable bootloader. I have been able to flash all LG KDZ firmware on it with LGUP, and have successfully flashed TWRP via fastboot and then rooted it. I've never had a problem flashing any ROMS, although I admit that I haven't tried all the custom ROMs out there. I prefer stock ROMs such as Fulmics 3.5 for the LG camera.
I picked up a new in box factory unlocked LG V30+ (LG-US998) on Amazon pretty cheap in December. What I didn't realize it that it is just running android 7.1.2 not 8 which I believe is the most current version available. I bought the unlocked version to avoid all the AT&T bloatware, but now I'm realizing it won't update OTA to the newest OS and is probably behind on security updates. Does anyone know what I need to do to get the phone to update OTA. I'm not interested in a custom rom or any of that, so if that means I need to flash the AT&T stock rom (with their bloatware) that's fine. I just want the phone to get OTA updates. I tried using the LG software to update it and it doesn't recognize the phone.
Refer to these two threads. Read through them, ignore the part about rooting if you won't be doing that.

You just need to update to latest US998 KDZ via software called LGUP.
See link below. You want steps 4 and 5.
FRANKENSTEIN INSTRUCTIONS
https://forum.xda-developers.com/showpost.php?p=76510671&postcount=168
Yes, those instructions are for converting to US998 -- but steps 4 and 5 still apply to someone just wanting to update US998 to most current firmware.
Install LGUP, download latest US998 KDZ (links provided), flash via Update mode. Easy.

An even better answer:
https://forum.xda-developers.com/lg-v30/help/lg-v30-oreo-t3831950
Just go to the US998 Oreo KDZ thread, install the LGUP attached there and download latest KDZ to update. Install via "Upgrade" mode in LGUP.

I read through but I'm a bit unsure of what I need to do. Do I need to unlock the bootloader or root it? I'm not interested in rooting it. Do I just download US99820h_00_0318.kdz and use the patched LGUP to install / flash it to my phone? I'm not sure where to get the proper patched version of LGUP to do this.

Yes, that's exactly what you do. It's like a manual OTA. You have the file, you use Upgrade mode with Dev Patched LGUP (which is more powerful than stock LGUP).

I had this same issue with my phone... Wouldn't ever get OTA updates... Honestly, the easiest way to get updates outside the kdz and lgup is to use the twrp stock builds. They're stock V30, you can get them without bloatware (US-998), and updating them is a piece of cake once you know what you're doing... In my case, the lack of updates seemed to have something to do with the fact that my device was somehow a Sprint device, blah blah blah....
Anyways, TWRP stock builds is the way to go... I'm currently running the Tmobile stock build and it's fine and does whatever I need it to... I like it better than custom

But they don't want to unlock bootloader and root, so I'm telling them the easy LGUP Upgrade mode method with latest US998 KDZ.
I agree TWRP flashable zip is fantastic. I use it, but for my wife's phone which is not bootloader unlocked or rooted (and my sister's phone also), the LGUP/KDZ method is where they need.

I hate to resurrect such an old post, but I never got around to doing this. Now that the quarantine is in place I have time. Is there a newer version of the kdz that I should use (probably Pie)? I'm guessing there's a newer version of LGUP (modified) as well?
Let me make sure I understand this too. I can use the modified version of LGUP to flash the newer kdz to my phone using the "upgrade" option and it keeps all the data currently on my phone, right? If later I wanted to do a factory reset on my phone, that would wipe the data but still retain the newer kdz that was installed, correct?

For US998, I only recommend updating to last Oreo 20h. I'm rooted, still on that. My wife, mother, sister, brother in law who are all NOT Bootloader Unlocked/Rooted are all still on that, also.
The one US998 Pie KDZ we received is very wonky. It's technically for U.S. Cellular. LG never released Pie KDZ for Open Market. Charging is slower, other things broken if you use other carriers.
Many people find it hard to update to, and if you have problems most of the workarounds depend on having TWRP.
I strongly recommend stable last Oreo 20h.
Yes, there is newer version of Dev Patched LGUP. I have it posted in the US998 Oreo and Pie KDZ threads, as well as Frankenstein.
Yes, if the use Upgrade mode you keep your data as long as you are already on earlier same firmware, in this case US998.
I have a stock US998 V30+ that is currently on Nougat. I am wanting to use LGUP to update to the latest version of stock Oreo. I am new to rooting and custom Android firmware, so I have a couple of questions about backups and firmware before I take the plunge.
1. I will probably eventually go to a custom firmware, but I would like to stay on stock right now. My plan is to upgrade to the most current version of Oreo through LGUP, create a backup there, downgrade to pre-July 2018 Oreo to unlock the bootloader and root, and then finally restore my backup of current stock Oreo. Would this allow me to root my phone and get the latest version of stock Oreo without losing my current phone data and apps?
2. Can I flash straight from Nougat to Oreo 20h? I saw in this post that it is recommended to flash 20e-20h individually through TWRP after root, but I wasn't sure if that applied to upgrading directly to 20h through LGUP.
3. Is it possible for me to create a full system backup of my Oreo install on stock before I root? I would essentially like to take an image of my OS and reload it after I root and wipe my phone.
Thanks in advance!

For bootloader, no need to update from Nougat to LATEST Oreo (20h), to then have to DOWNGRADE back to what you (temporarily) need for bootloader unlock and root (20a or 20b). Instead update to what you need for bootloader unlock and root (US998 20a or 20b), THEN update to 20h afterwards.

You can flash straight to Oreo 20h from Nougat, but if you need 20a or 20b FIRST for bootloader unlock, why would you waste effort doing it? That's having to backtrack.

Not before you root, no. That's something like TWRP or Titanium Backup does. When you unlock your bootloader your phone will be Hard Reset. Even AFTER that, you will purposely re-format your entire Data partition as part of the TWRP installation steps.
Having said that, Google DOES make backups of your apps and settings (if you have that option enabled) in the Cloud, and when you switch phones or make major updates like this (which is essentially a "new" phone), Android asks if you wish to "restore" the most recent history of apps and settings if possible. Say yes, have a good Wi-Fi connection, sit back and relax -- and all your apps and settings will restore.
After you go through all this, in TWRP yes you can then make a backup (RECOMMENDED!) for future use. In fact, you should always have a recent backup stored, just in case. You can also use Titanium Backup to make backups of all apps and data.

Ok that makes more sense. Thank you for clearing that up. My main reason for the suggestion about backtracking was because I thought that it might allow me to keep my current setup and data if I was already on Oreo to make a backup before unlocking the bootloader. It appears that won't be an option though.
Does flashing a stock kdz through LGUP without rooting format the device?

Depends on which LGUP option you use. Upgrade keeps data. Refurbish or Partition DL of all partitions does not. There are times you HAVE to do that.
You can plug in your phone to PC and transfer off any files you wish -- music, pictures, video, etc. Save as much stuff as you can, then transfer back later.

I have a US998 running the latest Verizon Oreo 20k. It tried to update to Pie but failed and since then, I've lost all fastboot commands. Prior to this, I had TWRP, and an unlocked bootloader. Now, it seems by bootloader is locked, and I cant get into download mode and downgrade with any .kdz via LGUP. Any suggestions?

You never had no fastboot flash commands while on Verizon firmware. You only have fastboot flash commands while on US998 firmware. That's why you had to temporarily Frankenstein to US998 to unlock the bootloader.
Why did you try to update to Pie OTA while you had TWRP custom recovery? OTA is ONLY for phones with full stock. We tell people over and over they will NEVER take OTA unless back in on full stock firmware.
Most people with TWRP freeze or disable the annoying OTA bags which are useless to them.
You should have waited for the TWRP-flashable zip that's coming...
Yeah, hindsight is 20-20. I installed stock 20k Verizon firmware, and took the OTA update. Wanted to play with Verizon's Pie for a bit. The update downloaded, but on rebooting, it failed. So now I'm still stuck on Verizon Oreo, no fastboot commands, unable to use LGUP to flash any .kdz. Lesson learned. Perhaps the guy on ebay can remote fix this.

You didn't install full stock firmware if you flashed with VS996 TWRP-flashable zip.
If you flashed full VS996 KDZ via Dev Patched LGUP, then yes that's installing stock firmware. And that would have wiped out TWRP, and safety allowed you to update with OTA.
HOWEVER, you would have no fastboot flash commands and no way to reinstall TWRP. You would then have to Frankenstein back to US998 for that.
Good news is your bootloader is still unlocked. You never locked it back. You just have no fastboot flash commands.
You've tried to manually go into download mode before opening Dev Patched LGUP?. Just asking.
(My hindsight isn't 20/20. I could have told you this would have happened if you'd ask questions. We tell people over and over not to try to take OTA after they install TWRP.
1) We have something better than crappy partial image OTA. We have full image KDZ and then TWRP flashable zips based on full image KDZ.
2) They will mess up their phones taking OTA with TWRP custom recovery installed. I'm sorry you didn't read the warnings.)
I don;t think anyone could predict that an OTA would wipe out download mode. Plenty have taken the Pie update without this happening. For ****s and giggles, I wanted to try Pie, and for me, the best way to do so was to do it via OTA on a fresh stock kdz. I didn't mind, as I can (could) easily get TWRP, root,etc back. However, the OTA didn't install (Verizon's fault?), there was an update installation error. I gave up, tried to kdz back to us998 like I've done successfully a bunch of times. But LGUP can't install any kdz because I lost download mode. It just gets to 4% and reboots back into the OS. I have a feeling my LAF is corrupted. Taking an OTA from Verizon that is meant for millions of phones shouldn't cause this sort of trouble but it did. I lost my ability to revert changes.
It appears the only way to get download mode back is to do it remotely via test points. Arghh.

So you did flash full VS996 Oreo KDZ? You had already gotten rid of TWRP prior to taking the OTA? I thought you had flashed V996 Oreo TWRP flashable zip and tried to take OTA with TWRP custom recovery still installed.
Then other than the crappy partial image OTA, I don't know why it didn't work.
Are you able to go into download mode manually before opening LGUP? If so, what I would suggest is re-installing Verizon Oreo KDZ via Refurbish mode to clean things up. Make sure you are using the NEW Dev Patched LGUP found in the Pie KDZ threads, not the older one found in the Oreo KDZ threads. The older one doesn't work to downgrade from Pie. Even though you didn't successfully update to Pie, something about your system may have changed.
Then after successfully reinstalling VS996 Oreo KDZ (if successful), then go full blown Frankenstein to US998: US998 Nougat, Master Reset, US998 Oreo.

See that thread. They recovered.
Unfortunately, I have somehow lost download mode, so LGUP will never work. Is it possible for an OTA to inactivate download mode? If so, that seems pretty shady, but not unlike Verizon. If Verizon is inactivating download mode, they're being selective (maybe by IMEI?) sonas not to be obvious about it.
From what I understand, the LAF partition is associated with download mode in LG phones, is it somehow possible to restore via LGUP an LAF image or whatever format that's in and maybe get LAF partition back?

You really need to unbrick this using qload 9008 and remote service from someone using octoplus, any button dance doesn't work to get download mode?

Yeah, as far as I know if LAF is borked on VS99620K then Octoplus is it, but I'll ask on Telegram to make sure. Good news is you can go into QLD 9008 mode for Octoplus repair using button dance and not necessarily need to open back of phone. There is a dude on XDA that'll do it for $15 instead of $35 (XDA discount)
EDIT: Found him: https://forum.xda-developers.com/member.php?u=6038524 (MFKilla). Here is what he offered few days ago: "For all xda members i have -20$ discount) Im from Moldova
And on my service no need disassemble the phone =)

That $15 is super cheap :laugh:
Thanks for the suggestions, everyone, I'll reach out to this guy and see what's what.
I have an unlocked AT&T V30 H931 that I've been using on Verizon with a stock Verizon Oreo ROM. I got a prompt this morning saying System Update 14 was ready to install, so I accepted the update. It proceeded to update until it got stuck on the white Verizon boot screen with the animated dots. I left it here for a while in case it would eventually make it past this, but I gave up after 90 minutes.
I can reboot, go to download mode, bring up the recovery menu, reset, choose safe mode - none of these change anything. Whenever I try to boot, it just hangs at that screen. I've tried using LGUP to revert to the Oreo ROM I had, but I get an error with that. To top it all off, my brothers have the same phones and ROMs and they're in the same boat I'm in after accepting this update.
So, what can I do at this point? I thought maybe I could install Pie via LGUP, but I haven't been able to find a place to download the appropriate files from.
Use newer Dev Patched LGUP that can handle Pie (some stuff changed before aborting, so you may have partial Pie).
Go into Download mode manually, Refurbish to most recent Oreo KDZ.
Master Reset.
See Instructions in post #3 of this thread, about downgrading to Oreo...
https://forum.xda-developers.com/lg-v30/development/vs996-lg-v30-vs99630a000704arb00-kdz-t3952254
Use the newer Dev Patched LGUP from that thread. Uninstall any prior version. Read the installation instructions.
______
Then wait for Verizon VS996 Pie KDZ to be released publicly.
Use same newer Dev Patched LGUP to install that, when available.
Great, it's working with the dual mode LGUP. Thanks!
Do you know why the OTA upgrade didn't work? I haven't had any trouble with previous OTAs, but of course this one is installing Pie.

Glad you recovered!
You aren't the only one who got bit by this. There's another thread going with almost same circumstances. Originally I thought he tried to install OTA with TWRP custom recovery still installed, but he was full VS996 stock (from US998), and he knows what he's doing.
No, I don't know why -- but I'm very distrustful of any partial image OTA updates. Learned that from Droid Turbo forum. I always prefer to manually flash full image, as it gives me more control.
Full image Pie KDZ for VS996 should be released publicly any day now.

Ok, I see. I'm making a mental note to wait for KDZ releases in the future.
One more question: my brother's phone, which has the same issue, has data on its internal storage that he hasn't backed up. Is there any way to downgrade without having to wipe the internal storage or perform a reset?

Probably won't work, but using Dev Patched LGUP he can TRY to use "Upgrade" mode to go back to most recent Oreo. It's not really Upgrade but if successful, it would keep his data.
If that doesn't work, then he needs to use Refurbish mode.
You're lucky, I lost download mode and the ability to LGUP and kdz. I've never had any problems using an OTA update when on stock firmware but I sure as hell learned my lesson. I feel sorry for those poor people that don't understand these issues and just take an OTA update because they don't know any better and lose features on their phones. Perhaps ignorance is bliss.

So you lost download mode after an OTA update? Just trying to understand whats happening here.
Yeah, on stock Verizon firmware, update restarted the phone, booted to a failed update screen, then back to the normal OS. But I don't see my unlocked bootloader warning screen anymore, and when I tried to use LGUP, I found I didn't have download mode anymore, so currently unable to flash any kdz.

What about TWRP?

Lost that, too. I've never had an OTA jack my phone up so bad, it's like it erased the LAF partition. My only option it seems is to use an Octopus Box.

Do you have stock recovery now?
Sent from my LG-VS980 using Tapatalk
I have nothing, if I try and adb into stock revcovery, I get a "no command" error, and no button combos can get me past that. Eventually, it just boots up normally.

I remember having similar instance of flashing one of the Verizon roms that I lost download mode too. I had to flash a us998 rom to fix it..

How do you flash without download mode? Did you have TWRP?

He's on stock firmware, so no TWRP.

You still have unlocked bootloader, but Verizon firmware doesn't have unlocked bootloader warning.
Some people in the past would flash parts of Verizon KDZ to get rid of the annoying bootloader unlock warning. But that's dangerous to mix and match.

So he probably flashed a stock rom, and hopefully flashed magisk, he'll have root. He can possibly recovery twrp with Flashify.

He Frankensteined to full stock VS9996 to see the Verizon Pie OTA. It didn't successfully install. He somehow lost Download mode and doesn't have fastboot flash commands -- since he's on VS996 firmware.
He DOES still have unlocked bootloader, but it can't do any good without being able to Frankenstein back to US998. He needs Download mode for that, to use Dev Patched LGUP.
If someone can capture the OTA .up file, couldn't that be installed with LGUP in FOTA mode? If the update succeeds, it should restore LAF.
I understand that's what H932 users who lost their LAF do to restore it. Haven't tried it myself, just pointing it out. Check the H932 lafsploit root thread for details.
Heck, try updating with LG Bridge. If it works, great, otherwise it should at least provide the OTA file. Again, as I understand, haven't tried myself
Edit: Even better, don't try to install the Pie update, but rather install the last security update with LGUP FOTA mode, if you can find the OTA file. Again, that's what H932 users do to restore a lost LAF partition.
