Can you try to flash again back to stock with kdz or .tot? that security error is mosttimes if you are deleting stuff from LG or adding things they don't like :/ Their Security error was "meant" to stop like virusses or hackers to acces everything, but they actually just made that for root users.

Stuck in Firmware Update Mode after

Hi Everyone,
I had received an update on PC suite for 5.0.2 lollipop and 65% of the way through it had stopped working and therefore my phone is stuck in Firmware Update mode and now I can get out of it.
I wasn't rooted but on the bottom of the box written in red it was saying ROOTED.
Previously I was using the 4.4.2 20h version
Please can you help as I don't really want to take it into LG as they probably will just ignore it
Thanks

How to lock bootloader for Lg Magna H502f

Hi. As i have rooted my phone i cannot update my phone to the latest official update by lg. Now my phone is not able to receive signal while in only 3g mode. Also cant locate gps well. i think this might be the problem because of the phone didnt updated yet.
Because of the phone has rooted i couldnt update. Someone please help me to lock the bootloader first and update to the latest version.

Help me please !!!!!!!!??

Hey Guys ,
I had a problem today with my lovely G6 ; since i bought it 2 months ago everything was working flawlessly (except the battery drain but generally i can say it is really a bad battery because just i think it's not able to stand for my needs like some other phones and complete the day)
till yesterday !!!
My LG G6 is currently running on Android Nougat 7.0 So,When i wanted to upgrade my Os into the latest Oreo update it ; the bad surprise came.
The OTA upgrade doesn't even work for me it always says you have currently the last update even like we know there is a lot of updates and security patches came for oreo !
So I tried the LG Bridge . yes, of course he detected my phone because i installed the latest driver pack but it keeps saying that it is impossible to chek the software version
So at this point , i got very confused about this phone and i did a lot of searches about its IMEI
My phone indicate at its menu that its model is the H873 which means it is The Canadian version but all the informations about my IMEI number i got from the intetnet it says that it is the VS988 model !!!
What should i do now :crying: please help me gyus i am very confused :crying:crying:
You bought it used or brand new from the official reseller? If not it's possible someone tampered with your device before. You can also try to flash the latest *.kdz via LG Up and Uppercut.
@Vatt`ghern
I bought used but if really someone tampered with it i should be able to be tampere with it and upgrade the software the main problem is that the model still uknown even for the PC howcan can i solve this miserable problem ?
Furthermore, I Tried LG UP too but it keeps saying model is uknown ?

Did you try LGUP instead of Bridge? It should recognize your phone.
You can try to flash Oreo with LGUP. Since you don't know for sure which variant you own I'll give two links: H873 VS988.
LGUP and UPPERCUT (Install LGUP and run Uppercut).
@Vatt`ghern
I tried LG UP , phone has been detected but it show me that my phone model is uknown

You most likely don't have any valid warranty on this phone so I would unlock the bootloader and try to install flashable zip through TWRP.
@Vatt`ghern
Excuse me Bro but I will be so greatful if you can give me a closer sight and help me to solve this problem because i haven't understand the process you are talking about . i have a very small basic knowledge about Flashing phones and TWRP

Download the platform tools (you don't have to download Android SDK) and check if your phone's bootloader can be actually unlocked, there is a guide how to do it.
