I looked around and it seems like some people want to downgrade just for root - even though 6.0 roots fine. And multiple methods are suggested.

So it would be nice if you could share something you know to work for d855.

Edit. Figured it out and got the outdated twrp installed. From: lg-g3/general/root-twrp-marshmallow-d855-30b-t3286268

Then updated to latest twrp from here and installed lineageos 15 official + their addon su. everything works.

In case anyone else who is also confused is stumbling on this you don't need to downgrade the ROM to kitkat just the bootloader and the app from the referenced thread above does it straight from the official android 6 - and other versions of it (autorec) would do it from android 5 as well. The only requirement is any root, and the thread above also gives you a KingRoot that works, it prob has some adware if not malware in it but that doesn't matter because you will be formatting the system partition anyway.
[G3 Android Development] SnowFuhrer:
The app btw, downgrades your bootloader. Glad it all worked.
[G3 Android Development] MrOS:
Good day!

Tell me which version of twrp is suitable for as985?

From vs985, us985 and ls990 does not fit.

Really looking forward to help.
[G3 Android Development] HardStyl3r:
This probably isn't supported.
[G3 Android Development] Verlog5454:
Why is this unofficial version is the one regarded as best? There is an official version of TWRP on their site for the G3.

So why does this version exist in high regard or why is it not co-opted to be the official version if it is better?
[G3 Android Development] HardStyl3r:
It is not the best, it's recommended as official one does not work.

I don't really want to become official.
[G3 Android Development] MrOS:
Very sorry! I was hoping that one of the options would do.
[G3 Android Development] pol098:
Having had to root a phone running Marshmallow, and with no knowledge initially, I'll fill in some of the blanks for anyone still keeping the G3 running who comes here via a search:

-Download a KitKat stock ROM image in KDZ (or TOT) format for your model from somewhere (easy to find). (I downloaded a v10a KDZ version, the oldest, and found that it had been kill-switched by McAfee anti-theft/virus. Hellish to fix - no download mode or access to the phone software). The "V10a" tells you how old a release is by the letter; V10a may be easier to root than, say V10n. (V20 is Lollipop, V30 Marshmallow)

- Install the latest available version of LGUP. Make sure that the DLL file in c:\Program Files (x86)\LG Electronics\LGUP\model\ is for 8974 (it's often supplied for G3 with incorrect 8994, reporting the phone as UNKNOWN), and flash the KitKat KDZ with it.

- I used Towelroot 3 rather than StumpRoot as it happens, but there are many ways to root a KitKat phone.

- Once you have some form of temproot, install SuperSU from the Play Store as an app and then into recovery, or some other permanent solution (Magisk) on the now-rooted phone. Install the TWRP application from the Play Store and use it to write a TWRP image to recovery.

- From what I've read, Flashify requires root.

HTH

First off, kudos for all of your hard work. and for all those that help guys like me who have questions... Currently G3 VS985 running RR 5.8.5 final using that last official TWRP 3.0.2. I have noticed something odd and just wanted some feedback. I have tried to update to later versions of RR and just recently CRDroid. They all require the updated TWRP Unofficial to install, so i have tried the 3.2.2 ver as well as the latest 3.3.1. ( i made sure i used the correct version for the vs985). Whenever i have updated TWRP, the install of those roms have no problems except i cannot get 4G data. Upon restoring back to my old rom (RR 5.8.5) i can longer get 4g either! (Yes i did have 4G before attempting to update TWRP and install another rom). The only way i can get back the 4G data is to downgrade to 10B, Root, install TWRP official, flash 35B Bootstack, install new RR, and finally restore back to configured RR. So knowing that i had this issue before, i downgraded again, root, TWRP (but used latest unofficial build 3.3.1), 35B bootstack, installed RR 5.8.5 and again no 4G. I can get 3G to work but not 4G. Any thoughts? Ideas? would love to upgrade to to PIE.

[G3 Android Development] Mechif:
I’m running LS990 g3 with stump root, twrp 2.85 (this version bumps the boot loader), I was boot looped trying to figure out nv band values in QXDM so I had to download a factory copy of the KitKat. Then did the above. Once I was rooted and bumped I upgraded to newest twrp. Then installed lineage 16 with Pico gapps. I’ve got full LTE now! It also had 3g and 4g with cloudy rom 2.5 but pie is so much better and amazing. Very happy with it. It took me forever to get to this point as there were lots of trial and errors. Hopefully this helps you.
[G3 Android Development] stslivealoha:
Mahalo for the info

Mahalo (thanks) for the info...happy to hear you were successful in dealing with your issue...I also was able to finally flash RR 7.0.2 with no issues. Not sure if I did anything differently other than i re-downloaded all of the software TWRP and RR,

LG G3 D850 - Fastboot after flashing

Hello,

I am new in the world of mobile modifications.

I have got a LG G3 D850 (It is a refurbish phone but system is saying D850, behind battery it is writen D850 and IME correspond to D850 ... so I asume it is a true D850 !).

I root it with LG OneClick root

Then I flash recovery using the D850 image I found on MEGA, using dd copy

First time I reboot in recovery mode, no TWRP but it ask me if I want to restore default and I say yes

My did not restore to default but is booting and everything ok in normal mode

But when I wand to go to recovery mode, no TWRP bug a console screen saying it is fastboot mode. To go out I add to remove battery or to reboot connecting USB and using "fastboot reboot"

Do you think it is a bug on D850 image or do I make something wrong ?

How to go out of this situation ? Everything is working well but I want to install LineageOS ...

Think you for you help.

Other more global question : Where can I found good resource on how Android and Phone are working ? Recovery, Fastboot ...
[G3 Android Development] Rob...:
How do you boot into the TWRP? Power and volume down buttons? Which ROM is installed?

Maybe try twrp from this forum.
[G3 Android Development] Stanislas81:
Think you for your help

I try to boot into recovery using "Power and volume down buttons" and "using adb reboot recovery" => Same problem

Installed ROM is officiel Android 4.2.2

The version of twrp is the one of this forum. I try to installe other version of official twrp with TWRP App, it said success but no change ...
[G3 Android Development] Rob...:
Sorry
[G3 Android Development] Stanislas81:
I think you did not finish your sentence ...
[G3 Android Development] Rob...:
if that does not work, I suspect that the official android version will overwrite twrp. In this case, you should not let android to boot after installing twrp. boot into the twrp first and install a custom rom.

Recovery: powered off, hold volume down+power. When LG Logo appears, release both buttons and then hold them again.
[G3 Android Development] Stanislas81:
The problem is that I never manage to boot into twrp. What I have try :

1.

Dowloading image of twrp for LG G3 D850 from this forum or from official (I try booth)

Copying to mobile with adb (adb push twrp-3.0.2-0-d850.img /sdcard/twrp-3.0.2-0-d850.img)

Login to shell with root (adb shell, su)

Flashing (dd if=/sdcard/twrp-3.0.2-0-d850.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery)

2.

Reebooting on recovery mode (powered off, hold volume down+power. When LG Logo appears, release both buttons and then hold them again)

Then I have a question asking if I want to reset factory default (no twrp 'logo'), I said Yes twice

Then it is showing a back screen with some log : [740] fastboot mode

If I connect usb I have other logs

If I reboot into normal mode (removing battery of fastboot reboot in terminal), everything ok

I I try to enter factory again, black screen with [740] fastboot mode

If I flash again, goto 2

It look like installation of twrp doesn't work ...

I will try other version of twrp ...
[G3 Android Development] Rob...:
I am sorry! On my device d855, TWRP was overwritten by the original firmware. Your device seems to be something else.

Did you try the 3.3.1.0 from this forum? If root is given it should work. You need a bumped Version. Official I don't know if is bumped.

Maybe someone with the same device can help here further.
[G3 Android Development] Stanislas81:
Yes, I first try this forum version ... then official version ...

What I can suspect (but it can be wrong has I havn't any experience) is that, as it is a refurbish phone, it is not a true d850 and then it can be compatibility probelms ... but I don't know how to check this, neither what to do :) I will try to understand more about software architecture.

Thanks for your help.
[G3 Android Development] Stanislas81:
I finally manage to install TWRP ! Here what I done for someone else :

To resume :

I have a LG 3G D850 refurbished

After installing TWRP, my phone was working but in recovery mode, instead of having TWRP I have fastboot console

Has it is a refurbished phone I was assuming it not really a d850. But I fear installing a bad TWRP image.

Has when I try to boot on recovery I get fastboot console, I use fastboot to try booting on image on my pc without having to flash. Like this I was able to try different TWRP version without (I assume !) any risk. fastboot boot twrp-xxx.img

With this I can see that d851 version of TWRP was working for my mobile. I then can flash it correctly.

The question is : How can everything saying that it was a d850 ... and only d851 image is working !
[G3 Android Development] HardStyl3r:
Basically the software will tell whatever it's programmed to say (or just the plain strings), so the best way to make sure what device are you using after buying new parts is just to actually to try it through trial and error. If the d851 software is working, start using D851 ROMs.
[G3 Android Development] Stanislas81:
That's a point of view :)

I am ok saying that software is saying what it's programmed to say. But I was assuming that there is difference between d851 and d850 ... so you can see the difference and then your can know witch real model it is !
[G3 Android Development] HardStyl3r:
There's huge difference, d851 is using BCMDHD chip and d850 is WCNSS. Huge deal.
[G3 Android Development] yahya69:
I just dd'd it into the recovery partition, but on next boot, I still see the stock recovery, which only has the option to erase all data. How do I actually get into TWRP?
[G3 Android Development] HardStyl3r:
By proceeding further, you'll see TWRP recovery if you flashed it successfully.
[G3 Android Development] yahya69:
I am the guy who contacted you via telegram. My problem was that LG refused to boot TWRP: LED flashing red and blue, "Secure boot error" displayed on screen, supposedly because the bootloader was locked and there was no way of unlocking it. I solved this by downgrading to KK with LGUP, then using LG One Click Root and then flashing TWRP through the official TWRP app, which finally allowed me to install LineageOS
[G3 Android Development] Андрей711:
please tell me if you plan to create twrp 3.3.1 with support for MultiROM?
[G3 Android Development] HardStyl3r:
I might do that, but no ETAs available. I am still learning how MultiROM works.
[G3 Android Development] Андрей711:
Too bad! It is very convenient to use. Let's hope that someday you can assemble it.

[MENTION=6880495]HardStyl3r[/MENTION]

Thanks for keeping our device recoveries up to date, however the latest build gives the "E:recv error on uevent" error during backups.

Did a Google search and found out it wasn't a big deal though.

Just giving feedback.

Thanks.

EDIT: Did another backup without the above issue.:eek:

All good now, evidently.
[G3 Android Development] dfunct:
[MENTION=6880495]HardStyl3r[/MENTION] may I ask why you did not bump the version/release number? This is a little confusing as won't really tell us immediately that a new version of TWRP is available. I had to actually see your comment and check the release date to realize it.

Besides, I see this is the unofficial channel. Do you think this version will be released on the twrp.me website at some point? Is this version needed for updating LineageOS 16 to 17.1? I currently have the official TWRP 3.3.1 installed.
[G3 Android Development] HardStyl3r:
I didn't bump the version, because it's not necessary to update. I think the changes I applied over the previous one will be official when they make it 100% Android Q compatible.
[G3 Android Development] mabs67:
[MENTION=6880495]HardStyl3r[/MENTION], many thanks for giving us Android 10 on our LG G3. It seems to work ok on my device. But for some reason I'm no longer able to boot neither to bootload nor recovery. I tried the manual way, via adb and also from the phone but is is booting to Android all the time. Any idea what I miss here?
[G3 Android Development] HardStyl3r:
My ROMs currently have that issue, but it will be solved this weekend.
[G3 Android Development] LZ_:
It should be always possible by the buton.... as described in

https://wiki.lineageos.org/devices/d855
[G3 Android Development] mabs67:
Thanks I actually know all of that, but for some reason it was not working when I was posting my question. Later on I got it working again, and can boot to recovery.

Now I'm looking forward for the up coming ROMs with the correct booting to recovery.
[G3 Android Development] w1ll1m:
Hi guys,

I have the same problem. After lineage OS update, I was not able to reboot into recovery nor fastboot using hardware buttons or apps. Is there a way to fix this?

I ran into the same problem above. I originally had MM, then tried downgrading to LP, but got the secure boot error as above. I downgraded to KK and did the exact same steps above before finally getting TWRP 3.3.1 and Lineageos 17.1 installed on the D852.

Hi !

Can it work on LG G3 D859 Daula Sim .

I made TWRP for this device 4 years ago .no when i flash same Twrp on Lolipop i got Secure boot certificate error.

How to fix that or Can i use your TWRP on Lolpop version will it work ?
[G3 Android Development] 64801965:
And how to enter into twrp?
[G3 Android Development] admiral.ackbar:
Start up phone from off state by simultaneously pressing Down Button + Power Button. Once the screen lights up with logo, release and IMMEDIATELY hold Down Button + Power Button until you are in recovery mode. It will ask you if you want to reset data twice. Selecting Yes will initiate Recovery, which has been replaced with TWRP software. You should be sure your data is backed up already in case something goes wrong this first time.
[LG V30 Questions & Answers] cmrntnnr:
I have a US998 v30s on Verizon with the stock Oreo 8.0 rom. A peculiarity is that no notification appears on the status bar after a voice message is received. What happens instead is that a text message is sent to the phone. The text message is "coded" and not intended to be read by humans. Nonetheless, it isn't hard to spot the caller id of the person who left the voice message within the text. Another text message is sent to the phone upon emptying the voice mail box. My suspicion is that these messages should turn on or off the voice message status bar notification. Is anyone familar with this behavior and how do I get the notifcations to work properly.

Thanks in advance for any assistance and apologies if this is asked an answered in another forum,

cmrntnnr
[LG V30 Questions & Answers] dvgb173:
Yup. This is one of the issues with using non-Verizon phones on Verizon.

VZW won't let you install the proprietary Verizon apk.

I'm hoping someone figures it out soon.

I like having an unlocked bootloader on Verizon.
[LG V30 Questions & Answers] jeston:
Had this problem too. I just started using Google Voice as my voicemail service instead. Works for me :good:
[LG V30 Questions & Answers] cmrntnnr:
It might yet be possible to get it working though I agree switching to google voice would be sesnible and easier, too. The reason for thinking so is that I have a droid turbo with resurrection remix as a backup phone. It has no verizon software, and the vms notifications work fine. Perhaps someone with one of [MENTION=3475147]SGCMarkus[/MENTION] roms on verizon can comment? If not, I'll give it a go eventually.
[LG V30 Questions & Answers] jjppott:
I think it is more likely related to just visual voicemail and not voicemail in general. I have us998 and use an MVNO whose repackaged service is Verizon. I have no issues with just voicemail, but when they tried enabling visual voicemail on my account, I started to get the weird texts. As soon as visual voicemail was disabled the texts went away and the standard voicemail notification started working again.
[LG V30 Questions & Answers] AdmiralKirk:
Visual VoiceMail or Advanced VoiceMail as its called in Verizon's business control panel is the cause. If you switch your service to Basic VoiceMail you wont get those anymore. Although I have to agree with everyone here that switching to Google Voice for Voicemail was the best option. After you sign up for Google Voice, google around for the special forwarding codes to use. Thier were two if memory serves, special numbers you can dial on your cell phone and then provide your Google Voice number. This makes all unanswered or denied calls go to your Google Voice number directly which will then take a message. Google Voice honestly does a much better job than Visual VoiceMail, even offering voicemail-to-text for free.
[LG V30 Questions & Answers] cmrntnnr:
Took the plunge and installed [MENTION=3475147]SGCMarkus[/MENTION]' DotOS rom. The voice message indicator is now working. The issue seems to be in the software of the open market v30.
[LG V30 Questions & Answers] my.ads0:
Really? So Visual Voicemail works properly on AOSP!?

Did you also install Stark's camera mod? Does it have all of the functionality of the stock camera?

Thanks for the feedback!
[LG V30 Questions & Answers] cmrntnnr:
It seems so, but I confess to not fully understand some of the Verizon nomenclature. Perhaps this helps get the correct conclusion. My service is basic, I dial *86 to get to voice messages, and I don't have any verizon software. The tape notification flips on and off properly with DotOS. The notification doesn't work with the stock lg software. I get a clunky text messages instead like described above.

I haven't tried Stark's camera but plan to soon.

Other lg apps like HD audio recorder and FM radio install but force close.
[LG V30 Questions & Answers] my.ads0:
Ahh. Visual Voicemail is the service/app that you use to access and listen to voicemails through the app on the screen. It sounds very different than what you are suggesting works (message notification). I am holding out on stock in hopes that someone will eventually get it to work.

Thanks for the feedback, though.

I just flashed the vs996 kdz. Left out the boot and recovery, visual VM is working! Wifi calling too!
[LG V30 Questions & Answers] dvgb173:
That is great news! I'll be trying that tonight.

Did you have to flash the 2 other files too?
[LG V30 Questions & Answers] suzook:
I loaded the kdz in lgup, used parttion upgrade, unchecked boot, and recovery....I did NOT reflash noencrypt or lgrootchecker, or magisk. It booted, still have root.

My service is better too. I already had the modem flashed, so there must be something with the actual 996 fw. I'm quite happy now.
[LG V30 Questions & Answers] dvgb173:
It is working, but I am getting some force closes and it can't read my sdcard.

EDIT: SD card corrupt. Tap to repair.

Format of SD card in phone fails. TWRP can't read it either. Bummer.

I have no force closes. I will pop an SD card in and check.

Edit....no issues with SD card either. Not sure why your having issues. Maybe try wiping data?

Can I load the vzw kdz on my open market us998?

From what I'm reading, it sounds like I can. I of course feel more comfortable when I can get others to confirm.

Thanks
[LG V30 Questions & Answers] suzook:
That I'm not sure about. Probably?
[LG V30 Questions & Answers] Ballroomblitz:
Thanks.

I probably should have mentioned that I am on Verizon and have unlocked bootloader with root. Shouldn't assume that folks know that. ;)
[LG V30 Questions & Answers] my.ads0:
:eek:

Wow! This is amazing! I'm on a converted ls as well. Thanks for testing this out!

Can you link to the kdz, please? I'm not sure where to find it.

Well, Suzook wrote:

The "ls" he's referring to is likely the LS998, which was a Sprint phone. If that's what it was, then he had to convert it to an unlocked US998 to be able to load the Verizon kdz, so you should be able to do the same thing. Should, of course, being the operative word. :)
[LG V30 Questions & Answers] suzook:
https://lg-firmwares.com/downloads-...s996_north_america_vs99620b_03_0312_arb00_kdz

That's kdz. Yes, I have a ls converted to us998 rooted with twrp. I dirty flashed over the rooted us998 fw
[LG V30 Questions & Answers] my.ads0:
Thanks for the link, Suzook. Much appreciated.

But are you sure you "dirty flashed"? I thought kdz'ing was more of a nuclear bomb rather than a bright little flash.
[LG V30 Questions & Answers] ChazzMatt:
Not quite a dirty flash as you unchecked some category in LGUP DL PARTITION method, right?
[LG V30 Questions & Answers] suzook:
That's true, I unchecked recovery, and boot. By dirty, I meant I kept data and all.
[LG V30 Questions & Answers] my.ads0:
Wait...so doing the kdz method doesn't delete photos and such? It only overwrites the ROM?
