Here is my problem.
While trying to upgrading my phone through LG offline KDZ updater or UpTestEX, when it reaches to MTK starts, it gives error:
LGUSERCS Tool has stopped working.
Any solution?
I keep getting a message on the LG startup screen, that says,
"secure booting error
cause: boot certification verify"
My phone was rooted using king root almost 6 months ago, and I had no problems with it. Until around a month ago, it started getting real slow and apps would randomly stop. So I decided to format the phone. There weren't many problems after that. but after a while it started getting slow again, but slower than the first time. One day almost every app closed and "LG Home" would close, it would give me some kind of error. I turned it off and tried turning it back on, but that's when I got that error. At first i thought my phone was bricked, i still sort of do, so I tried several methods. I can only turn the phone on in download mode, and my computer recognizes it as an android device.
At first I had some problems because i couldn't find my right .KDZ file, I used KDZ Update and I tried using LGFlash tool, but i can't find any of the files (.bin . dll) I need. I've also tried using the 2014 version of the LGFlash and used the LG Mobile Support tool, and nothing! They all take around 4 to 5 hours to finish!!! It never says there's an error or anything, none of them do! They always finish successfully, but the same thing keeps happening. Every time the phone reboots, it gets stuck on the LG logo and i get the secure booting Error!! What else can i try? Any suggestions? Am i missing something? All drivers are installed correctly and I've tried on windows 7, 8 and 10! Is there anybody who can help me? What do you think the problem could be? What causes the "secure booting Error!"?? :crying: :fingers-crossed:

Hi, Thanks for using XDA assist
It looks like there is no dedicated forum for your device, however
There is a general forum for android here http://forum.xda-developers.com/android/help where you can try to ask to get expert's help.
Good luck.
After messing up with system files BIULD.prop I got stuck in bootloop.
I could find the KDZ but when using LG Flash Tool after 4% it keeps saying phone disconnected try again. I used KDZ f/w update it keeps saying extract error. Even when using Verizon software update I got the same error phone disconnected.
Please help I can't recover my phone.
hi everyone
i have a lg m250e and last week i tried to flash it with lgflashtools 2014 and it didnt worked out and gave me "server connection failed error ", in lgup the error was "0x2bc" and in the latest version of lgflashtools the error was "dodownload error".
after awhile that i was trying to solve these errors my phone wont bootup and just come up to "frimware update" screen and wiping our pressing power and vlome down bottens can not solve the problem.
now i only want my phone come up.
how i can flash it ?
is there a way to boot it up with its own android?
thanks.
Hello everyone, I hope you are very well.
A few days ago, a family brought me a phone to try to fix it, it is an LG MS330.
The phone turns on, shows the typical LG logo and after a few seconds it shows the message:
Security Error
[Authentication Fail # 9] [MODIFIED]

Which makes me think that someone installed an unofficial firmware on it and was what caused the problem. Everything normal up to here, the real problem happens when I try to flash the device through the download mode, where it shows me the following error:
Secure booting Error!
Error code : 1009
MODIFIED !!
Click to expand...
Click to collapse
After a few seconds of throwing this error, the phone automatically shuts down and restarts.
The real problem is that it does not let me under any circumstances flash the firmware of the phone and I also cannot create the connection between the computer and the phone to be able to flash it.
I have tried various programs such as LG Flash Tool, LG UP, LG Mobile Support and have not been successful with any.
Could anyone help me please?
I really don't know what to do at this point anymore. Does the phone have salvation? Is there something that can be done?
