Unable to unbrick my LG G2(vs980)..Crossdl [l01f] to [vs980]

Hello guys, I have an Lg g2(vs980). Some days ago, I flashed Grolla rom on it and then it always booted in fastboot mode. Then somehow I got it into the download mode. I thought that it would be easy now to flash through lg flash tool. First I tried Kdz method but it always stopped at 2%. Then I tried tot method but every time I try to install the tot file, if I use vs980 dll file it shows me the error "Phone model is different. Check phone or dll" and if I use universal dll for lg mobile it shows me error"Crossdl [l01f] to [vs980].
Its been 3 days I am trying to unbrick my phone but all in vain. Somebody please help me.....
I solved my problem. It was a simple mistake that wasted my whole day. I didn't replaced the megalock.dll file in lg flash tool dirctory with the given megalock.dll file. After replacing, i used the universal dll file with my tot file and i was able to flash. Thankx Allah.

[HELP] LG MS330 - [Authentication Fail #9] [MODIFIED]

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]
Click to expand...
Click to collapse
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?
