[Firmware](Upgrade+Root/Downgrade/Unroot) Files+Flashing Guide [TOT/KDZ/TWRP] 7/07/19

[Doctor DrOiiD]

I bought lg g3 d851..
The box isn't like the one in YouTube videos it doesn't have T-Mobile logo on it..just written d851
And the back cover doesn't have T-Mobile logo which should be there
But under the cover and under the battery is written d851 and when I power the phone there is T-Mobile logo and I tried hidden menu cod for T-Mobile model and worked
The firmware version is v10z! And it doesn't belong to any model
And baseband version is vs985 which belong to Verizon!
And when I connected to of in download mod it shows lge androidnet for vsw USB port which belong to Verizon! And lg flash tool and PC suit doesn't recognize my phone
And tried to install T-Mobile twrp it didn't work..but when I tried Verizon twrp it worked!
I backup my ROM via twrp and I want to flash android 6
What should I do

What should I do

You should return the device. Someone has highly tampered with it. And sold it as something that it's not.

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:

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.

If there's noantirollback, did you attempt to flash with the device booted into android and letting LGUP reboot the phone into download mode?

Antirollback means no downgrading. But LGUP will stop you if it is. But did you try what I stated above?

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.

[farouk405]

You are using a USB 2.0 port correct? USB 3.0 wont work. And can you try another computer?

 

[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

Did you install of the dll file installers from the lgup download right?

And no you will need to use LGUP.

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

the info doesnt even fill right, and I do not know why in the slightest,

what it says is

Modem port -1 USB Serial port 1
Connect mode Normal (Booted in Download mode)
Model name ___
ESN/IMEA ____
Phone S/W Ver ____
battery level 0 (required level >=4) (at 100% charge)
Phone number ____
Chip type Error
SmartphoneType ____
Android version ____
LTE DL Mode check N
SetAuthmark This chipset not support authmark
(same for get)
Password ___
IFXNVDB (INF ONLY) INF CHIP ONLY
Prevent upgrade Supported the Upgrade

in box on right above PC Mem check

IMEI EMPTY
IMEI AUTH FAIL please check IMEI Value

Phone mode normal
Phone model ___
Server model ___
Buyer ____
phone ver ___
Server ver ____
**Phone sub version length is more than 2 digit
**Server version is empty
Please check imei or S/W file status in CSMG

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?

It appears that both TOT and KDZ are impossible to do with D85130e.

---------- Post added at 07:02 PM ---------- Previous post was at 06:39 PM ----------

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.
