Flashed it with LGH90130d kdz, 30c, 20c 20e, 30c firmwares using LGUP. Every one of them was fully flashed till 100% but phone goes to dead mode (doesn't reboot) after the flashing finishes. which file should i flash exactly. my original firmware was t-mobile lollipop 5.1.1 LGH90110c. Can you please point me out what i didn't do exactly?


Sounds like a permanent brick. If you ever attempted to roll back to an older version of firmware that would’ve tripped antirollback

I've taken it to a service shop to flash it with Octopus box, that guy tried to flash it with lgh90120c firmware but he bricked it with just a black screen then i got back and flashed it with H90021w Unbrick Qfil with Qpst. Phone now boots in firmware update and fastboot mode nothing else.
I made a rawprogram.xml file with LGH90130d kdz firmware and flashed the phone with Qpst it was flashed but then no response as usual. I need a solution. Don't know what else I need to do.

no didn't try to roll back to any older version but i tried to update it with a newer version using LGUP. When my phone didn't response after flash has been done then I noticed that I flashed the wrong firmware. I got the file from lg-firmware.com site which was LGH90130d.

LGUP Method flashes both KDZ & TOT files:
Thanks to @shakeyabooti for LGUP!

Download LGUP from HERE
Install the file with the DLL name in them first and then LGUP_Install_Ver_1_14_3 Then copy the folder "common" to C:\Program Files (x86)\LG Electronics\LGUP\model (this should resolve unknown error)
Make sure you have downloaded the required KDZ file MM or LP
Open LGUP on your computer "make sure your phone is plugged in"
ARE YOU HAVING TROUBLE WITH LGUP NOT SEEING YOUR MOBILE?
Try this....... take the back off your mobile so you can get at the battery. Connect your mobile via USB. Start LGUP, if it does not see your phone DO NOT DISCONNECT, DO NOT RESTART OR TURN OFF LGUP. Take out the battery and then put it back in.......let the phone restart on its own. LGUP should now see it.

LG Drivers: All Others - HERE Verizon - HERE


TO DO A FULL WIPE AND INSTALL MM - Open the LGUP on your computer. FILE PATH point it towards the MM KDZ.
IMPORTANT!!!!!!! shut down LGUP!
Now open LGUP again - you will notice that the MM KDZ will still be showing in the FILE PATH section. Select REFURBISH and make sure BIN file is ticked. Press Start. Make cup of tea and be patient

TO GO BACK TO LP FROM MM - Open LGUP on your computer, click on FILE PATH and point it towards your LP KDZ. Close LGUP and re-open LGUP. Make sure you select REFURBISH this will do a FULL wipe, tick BIN file. Press Start. Make cup of tea and be patient​

Hi bro hyelton,
I read all your thread, because really LG in these models, it is a controversy and it is a terminal garbage for all the possible details that was to be a like bricked! :(

Question!
How do you know, when the “Anti-rollback Security System” is active, how can you check this before flashing any ROM Firmware in these Series of Terminals? :confused:

According to what I have been able to understand from all this and I want you to rectify if I am wrong about something regarding these LG series (Model: LG-H9XX): :fingers-crossed:

1. You must pre-flash the New ROM and even after flashing, you will a Factory Hard Reset. (To eliminate old cache that can intervene and cause errors in the functions of some APKs). ;)

2. If you have an LG-H9XX, and it is with the Android 5.1.1 Lollipop´ ROM, you can upgrade it to the Android 6.0 Marshmallow version with the LGUP or UPPERCUT Softwares. But if you are already in the Masmallow 6.0, you will have to die with that ROM for life, since the Anti-rollback protection will be activated, this means that you can never return to the previous version, it may also be the case that some functions such as Fingerprint in Security, do not work very well. Also, do not pick up a signal or that it is blocked when you insert your operator's SIM card, after flashing to the Massmallow 6.0 version. This is at your risk! That is, this entails many risks and it is NOT recommended to do it unless you need it!
Note! If you have an Android Marshmallow Operating System, you CANNOT use LGUP or UPPERCUT Software, it will give update errors. Only Lollipop or other system... :fingers-crossed:

3. If you are in the Marshmallow 6.0 version with the problems described above, the entire phone will be lost and the only way to recover it is to change the complete Board Replacement of the LG-H9XX. :mad:

4. If you are wrong to select the model of the ROM when you are going to upgrade your Lollipop Stock 5.1.1 to Marshmallow 6.0 you have turned your phone into a brick, since there is no going back, you have to buy the new Board Replacement. Please note that updates can be automatic from the same Terminal to LG server! :mad:

5. If your Mobile on the outside claims to be an LG-H9XX but actually inside the Terminal it has a Verizon VS990 Board with a deceptive Operating System (scammed and emulated) of a ROM with the LG-H9XX Operating System of the AT&T, to deceive and scam people and to top it all Upgraded your Mobile to a new version of the H9XX of AT&T. You will lose your Terminal for a lifetime, since you are installing a ROM Firmware (Update) that does NOT really correspond to your Board and the Protection Antirollback is activated! :(

SUMMARIZING!
DO NOT buy LG of these series and DO NOT upgrade to a higher version or to a Custom ROM, if your Terminal works well as it is. The series of LG-H9XX is very S h i_

:mad: :eek:

Sorry my English ok.

Hi bro! In this year 2020 is the same Flash Tools v1.8.1.1023 used or should a newer version be used?
What is the difference of FlashTools 2014, only work KDZ files?
You can clarify! :confused:
