I do not have twrp and I'm already on d85130e

I have d85130e lg g3 but I do not have twrp, or anything like that, it is supposed to assume that those who want to root and never installed Twrp will not be able to use this method.

Everything is useless, nothing works.

Simply impossible to root the d85130e.

I can not go back to d851xxx because I do not have twrp nor way to install it since I am not root and I can not become root.

What a great dilemma :crying::crying::crying::crying:
[T-Mobile LG G3] hyelton:
Does 30e have antirollback? To downgrade back to 20x. I haven't kept up with recent firmwares for that model. Is there's no antirollback you would be able to downgrade.
[T-Mobile LG G3] farouk405:
please help me

my phone d851 with 30e

i want to downgrade to 20E lolipop

i try with lgup

but unknown device although the driver is instaled
[T-Mobile LG G3] hyelton:
If there's noantirollback, did you attempt to flash with the device booted into android and letting LGUP reboot the phone into download mode?
[T-Mobile LG G3] farouk405:
thnx for answer

my english is very bad

what you mean by noantirollback??

---

the problem is

[IMG="b"]http://www.3rbz.com/uploads/4d2a8d9ace671.png[/IMG]

when i click select a message appear " you have to select a known model"

although the driver is installed correctly

[IMG="a"]http://www.3rbz.com/uploads/d586e0af6a871.png[/IMG]
[T-Mobile LG G3] hyelton:
Antirollback means no downgrading. But LGUP will stop you if it is. But did you try what I stated above?
[T-Mobile LG G3] farouk405:
so idont have Posibility to enter to the program and select the kdz file D85120E_00

to downgrade from 30E
[T-Mobile LG G3] hyelton:
Don't know that for sure as I can't keep up with all the device models and there versions. But did you try what I stated above? You get unknown model in download mode that's normal. You need to booted into android for it to detect the device.
[T-Mobile LG G3] farouk405:
yes i tried with the phone booted in android .

and i seleceted mtp

but lgup still in unknown model so lgup cant restart the phone in downlaod mode

---------- Post added at 11:15 PM ---------- Previous post was at 11:09 PM ----------

yes i said that the msg of unknown model appear when the phone is in android with MTP

how can i pass this obstacle
[T-Mobile LG G3] hyelton:
You are using a USB 2.0 port correct? USB 3.0 wont work. And can you try another computer?
[T-Mobile LG G3] farouk405:
yes i tried an another computer with a diffirent os

and im using a port usb 2.0 not 3.0.

I have a doubt about the cable because it is not original

---------- Post added at 11:45 PM ---------- Previous post was at 11:27 PM ----------

there is another method to downgrad from mm ?
[T-Mobile LG G3] hyelton:
Did you install of the dll file installers from the lgup download right?

And no you will need to use LGUP.
[T-Mobile LG G3] farouk405:
thnx a lot

i forgot the dll file

now it's ok

Im trying to do KDZ restore on my D851 but i keep getting an error Unable to connect to server, then when it is doing the S/W update, it gets to 4% then breaks

now this happens instead no matter the port layout

I have no idea what any of that means, all i know is my phones been out of commission for like 3 years and i want it back enough if i had to send it to someone i would.

TOT attempted just sits on "Waiting for connection." when i UNPLUG then it does its attempt. and this is with both Update and Board DLL

LGUP also does not detect my model as with farouk405 I Difference being I CANNOT load android at all. mine is soft bricked at boot goes to LG Scree, then goes black and sits there for hours until battery dies.

Following the information i read from hyelton helping Farouk I am going to plug into USB 2.0 (As have been using 3.0)

My Tmobile service has been disabled for.... 5 years? Still owe on the phone, trying to setup payments again to finish paying it off, could that have a hand in this issue set?

Ok, I spoke too soon on the KDZ. I was trying to do 30b and it wasn't working at all.

I hunted down a version of 30d and I was able to get that flashed. Now to see if the next steps work. :)

It is probably something other than 8.1 because I have done it on 8.1 many times successfully.

Hi there, I'm relatively new to the community here and during this process, it freezes and tells me the phone was disconnected while it wasn't. It stops at 15%. I'm using W8.1. Any help or ideas will be very appreciated. I did follow all steps and I'm downloading c++

Thanks for posting this thread. I got an error saying connection to the server couldn't be made, but I just left the error up on the screen and noticed that it kept going through the process and all is good. Took about 5 minutes total.

my issue is using the tool it's asking for a b2c client tool.... any suggestions to fix this
[T-Mobile LG G3] albertzelaya:
It worked perfectly for me. Thanks a lot for this. I had rooted and when I click the full unroot button on the su app it uprooted. But the phone was still registering as rooted on the dialer hidden menu. Since I got the camera issue and I want to replace this phone. This worked perfectly for me. Not shows not rooted. Idk if by doing this it might have fixed the camera issue or not. But for not its gone. I'm able to zoom in while recording. Thanks again.
[T-Mobile LG G3] KiNG OMaR:
Doesn't work on Windows 8.1 for me. Tried this method, soft bricked my phone because it didn't flash all the way. Tried the .tot method and that also failed after 40 minutes.

Copied files to flash drive, moved to a Windows 7 pc, finished within 5 minutes.

Some people are having luck with this on Windows 8, but I'm just not one of those people. Hope this helps anyone who's stuck on Windows 8!
[T-Mobile LG G3] twiifm:
Didn't work on Win 8.1 Parallels but worked w Bootcamp Win 7 for me.

I think its the usb drivers
[T-Mobile LG G3] RichieRich84:
So this worked after I wiped my phone in twrp by accident when I was going to flash a new rom. Im on win7. Now if I flash any rom my phone it wont connect to my laptop. I cant figure out what my issue is. I also used the tot method. Been using dropbox to send files to my phone from laptop as walk around.
[T-Mobile LG G3] ThePagel:
Try to reinstall the driver or just uninstall and let windows automatically install it.
[T-Mobile LG G3] RichieRich84:
I already got drivers installed. The mtp driver fails to download while the other drivers install from windows. Also phone shows up as a media device instead of mass storage device, but opens extra folder as mass storage device on stock rom.
[T-Mobile LG G3] ThePagel:
You may have got a bad kdz flash but i doubt its that. Most likely on your computers side. If you can, plug into a different pc or usb slot. Odd things happen and I find some of the most irritating problems have a simple answer.
[T-Mobile LG G3] RichieRich84:
Could be my on my laptop side of things.
[T-Mobile LG G3] twiifm:
For me the problem was the files never got uploaded to phone. I got to the LG update tool but it always stopped before finishing

Once all the files upload. The flashing occurs on the phone. So i think it has to do w usb drivers

When used Win 7 using bootcamp it worked
[T-Mobile LG G3] antawnm26:
I'm on windows 8.1 it worked for me
[T-Mobile LG G3] RichieRich84:
Figured a Quick fix. Restore to stock (kdz), root, change setting to mtp, dirty flash rom worked for me.
[T-Mobile LG G3] inshadesofgrey:
Hi - I followed these instructions, but I must have done something wrong.

My first try FAILED (with " ???? " all over the error code on the computer), and now the phone is stuck on the "FIRMWARE UPDATE - Do not unplug the USB connection until the process is finished - USER B51" screen

No matter what i do (all key combinations for recovery mode, download mode), plugging, unplugging the phone, taking the battery out for 30 mins or so, and putting it back - NOTHING is working. It all goes back to the screen mentioned above.

I tried running the LG Flash tool again, but it fails.

Any ideas? Any help would be greatly appreciated. This phone is my daily driver, and I am in a major fix without it.
[T-Mobile LG G3] twiifm:
Keep trying w different computers. Same thing happened to me.

Your phone can go into download mode right?
[T-Mobile LG G3] ThePagel:
Im going to do some testing when I get a chance because I think a recent 8.1 update has made this tool unreliable. If that is the case it should be a fairly easy problem to get around.
[T-Mobile LG G3] inshadesofgrey:
The phone is stuck at the "FIRMWARE UPDATE - don't unplug usb...... - 0% ......" screen.

is that the DL mode?
[T-Mobile LG G3] albertzelaya:
I got the pop up window with the ??????? Usb????? Something else i cant remember. I didnt click anything and left that window open and let the process finish. Took a long time over 40 min. But i just assumed it was because of my old and slow laptop. It worked perfectly for me. Just took a long time.

Idk if this helps at all. Just letting you know what happened when i did it.

Help downgrade TOT

Good afternoon, I have a problem, I have followed all the steps of the guide, I am trying to downgrade it, but when it starts everything tells me the flashtool that can not read the device information 00000m imei null pim null.

In lgup I get error 4:42:37 some error with the bin.

I'm connected on port 41. I do not know what else to do :c, I'm about to try with the ToT of the D801AT to see what happens. I need help I'm stuck in Marshmallow 30e, aaah I tried to downgrade with flash2014 and could not either I could not go to the 30d :c
[T-Mobile LG G3] Xplorer4x4:
I followed the directions for the tot method(had to use the generic dll instead of the one with the tot(due to model fail check). However I have another problem while using the generic dll. Screenshot attached:

[T-Mobile LG G3] SolidSnake01:
hello thank you for this alternative method but have one question. Why is there no need to download, copy and past megalock to the lg folder created in the C: drive like other methods indicate?
[T-Mobile LG G3] hyelton:
But you do need the megalock dll..,the kdz method doesn’t require this. The tot flash tool is the one that requires it
[T-Mobile LG G3] ThePagel:
Sorry for the super late reply!

I try to make everything as turn key as possible. So in this release everything is already installed and the megalock is already in the folder. No need to move it around, works as is.

Years have come and gone and I seemed to have forgotten about this thread... Well I am back and going to do a full update to the OP since its sticky as well as add some content and mirrors!

For now here is what I have added:

KDZ

D85130g_00_0420 (07/05/17)

D85130e_00_0711 (08/08/16)

D85130d_00_0404 (05/02/16)

D85120G_00 (10/05/15)

TWRP

D85120G_00-Untouched_Stock_Restore

D85130d_00_0404-Untouched_Stock_Restore

D85130e_00_0711-Untouched_Stock_Restore

D85130g_00_0420-Untouched_Stock_Restore

EXTRAS (Bottom of OP)

All files in the KDZ files except System.img

I will also be adding the updated tot/kdz method to upgrade or downgrade. When I am finished it will be the final version. All relevant stock files and restore/upgrade/downgrade methods will be available in the OP with enough mirrors to ensure the files will be around for another 5+ years.
[T-Mobile LG G3] kahriman:
Why can't I see the contents, download files?
[T-Mobile LG G3] ThePagel:
Are you using 7zip?
[T-Mobile LG G3] twiifm:
I think so. You press volume up and plug in cable. An icon of computer appears then you get message about firmware update i think.

My phone was bootlooped after a bad flash. But I forgot what. Maybe volume boost mod. I used the method in this thread to go back to stock.

Everything worked correctly except the last step of rom being uploaded to phone. Sounds like you have same issue. The firmware doesn't upload to phone

I have a macbook using Win 8.1 thru Parallels. Didn't work. Then I tried it on an iMac that had Win 7 thru Bootcamp. That worked.

I believe it has something to do w LG usb drivers.

After the rom is uploaded to phone the flashing takes place on the phone. The steps on your PC is to upload the firmware.

Try another PC and good luck. I've had this happen to me w past devices Samsung & HTC. As long as phone turns on and you can go into DL mode you can probably flash. Only one time I had an Galaxy S2 that had a damaged USB port I couldn't do this until I replaced the port
[T-Mobile LG G3] inshadesofgrey:
FIXED IT!

EDIT - SOLVED

Thanks to everyone who chipped but especially to pside15 and one other person (but i can't find his post)

The solution was very simple - I was making the idiotic mistake of looking at just the computer screen and NOT the phone screen. The computer kept giving me all sorts of errors saying 'update failed - can't connect to server, yada yada' etc. I just left the phone alone - came back 10 mins later to working phone.

Moral of the story - Watch BOTH the phone screen and the computer while doing these things, because my computer had me believe that this is not gonna work - the phone obviously disagreed

[T-Mobile LG G3] DigitalChris602:
Just had a near brick experience today. My phone saw it's life flash before it's eyes. Now, I've used this restore method many times before with no issues, but today was trouble. I think I figured out what went wrong. I installed Fallout New Vegas on my computer after a reformat of the drive. While installing the game, it also installed DirectX 9.0 I think when that happened some other things on the computer were also downgraded and caused my problems. I downloaded the latest microsoft runtime update, it worked. But this time it took about a half hour rather than the few minutes it usually takes.
[T-Mobile LG G3] ThePagel:
Yeah I have been thinking about what the best way to go about this would be and I think if this can run in wine that would be the perfect universal fix. I'll try that this weekend I'll make a virtualbox pre setup that way if problems happen it can be a fall back method. I hate the feeling of knowing you can fix something but your computer isn't cooperating.
[T-Mobile LG G3] wpboyce:
I was wondering if there was a way to just flash the radio from the new update with this, I am rooted and have done several mods and don't want to flash back to stock and redo all the mods just to get what ever the update did

[T-Mobile LG G3] ThePagel:
Yeah that's the problem I haven't updated the op yet but I really should. This can work on 8.1 64 but its buggy when it does work.

[T-Mobile LG G3] ThePagel:
Which method should you use?

I cannot tell you which one is best for you so I will tell you the strengths and weaknesses of each method

Ill add more as I think of them

BACK TO OP​

TOT

Strengths:

Works without root

Unbrick 99% of the time

Restores every partition

Restores SOME bricks that normally require a debrick.img

Works on win vista, win7, win8/8.1 x86 and x64

Weaknesses:

Full wipe every time (not external sd)

Takes longer than KDZ and TWRP

Many steps that might confuse some users

Replaces kernel and custom recovery (dirty flashers will need to re-install their custom kernels and twrp)

KDZ

Strengths:

Works without root

Full wipe or no wipe option (you can use NORMAL FLASH to upgrade firmware and not lose anything)

Fast compared to tot

Easy to use (if it runs for you)

Weaknesses:

Runs poorly on win8/8.1 x64 and may not even work in some cases

Restores limited bricks compared to tot

Replaces kernel and custom recovery (dirty flashers will need to re-install their custom kernels and twrp)

TWRP

Strengths:

Honestly preferred method unless you severely messed up your phone

Works when tot and kdz will not run on your pc (if you can access recovery)

Upgrade firmware like its a rom (installs stock: system, kernel, modem, recovery and rpm)

Downgrade firmware like its a rom (installs stock: system, kernel, modem,recovery and rpm)

Fresh untouched firmware like its a rom (installs stock: system, kernel, modem, recovery and rpm)

Re-root from twrp before reboot [don't forget to re-install TWRP easiest way is with TWRP manager from the play store]

Weaknesses:

Will only recover from system bricks

Requires root

Replaces kernel and custom recovery (dirty flashers will need to re-install their custom kernels and twrp)

BACK TO OP​
[T-Mobile LG G3] mingkee:
I had same problem unpacking the files.

You should check is it compatible with your platform.

Eventually I got them unpacked in Win8.1 and brought my G3 back to service.
[T-Mobile LG G3] mapobean:
problem unzipping

most of the time when you cannot unpack a zip it is due to not getting the complete download. I would re download the files and verify the MD5 check sums.
[T-Mobile LG G3] hudhacks:
Has anyone flashed the kdz on linux?

I would like to use the kdz file to get back on stock, though I only have linux systems.

The only flash instructions I have seen in this thread are for windows systems, are there instructions for linux?

TWRP Files/flashing guide

(This is a WIP)

Download your preferred choice of D851xxx-Untouched_Stock_Restore.zip HERE (Perfect 1:1 image unlike most roms)

Copy D851xxx-Untouched_Stock_Restore.zip to phone (external sd if available)

Reboot into twrp

For firmware update do not wipe! skip to step 8. If you want untouched stock continue with step 4.

Click [Wipe]

Click [Advanced Wipe] (For full wipe stock restore only)

Select dalvik cache, system, Data, Internal storage (only if you use external for downloaded file) and cache

Click the home Icon in the bottom left

Click [Install]

Select D851xxx-Untouched_Stock_Restore.zip (make sure you select the proper sd card)

Swipe to install [====>]

Install will now begin: pure stock system, pure stock kernel, pure stock recovery, modem and rpm will be installed

After completion click [wipe cache/dalvik] (do not skip especially if you dirty flashed)

Swipe to wipe [====>]

Click [back]

Click [reboot system] (it might say no os but it is wrong you do have a os click restart anyway) [dirty flash will not have that problem]

DO NOT INSTALL ROOT UNLESS YOU WANT IT TO BE ROOTED

If you did a dirty flash to update you need to reinstall twrp! (goo manager or twrp manager from the play store is the easiest way)
