Thank you so much sir
It worked for me!
For those of you who donot know how this works
All you have to do is
Place the caynogen mod 11 zip file on your desktop
Open it using WinZip
Then open META-INF
Then open com
Then double click google
And then open android
Now what you see is 2 files
Now what you have to do is drag and drop the "updater script" on your desktop
Now, open this updater-script with a piece of software called "Notepad ++"
Now make changes as described in the comments above by k2wl (I.e changes from w7 to w7ds)
And then save it
Now what you have to do is drag and drop this modified updater script rite back into the zip and hit enter
And then paste this modified zip into your ext SD card
And flash cm mod 11 as usual to your lg l90 D410ds
I know it was all explained in the comments above but when I first read them I had no idea how to find and edit the updater script
So I tried to make it easy for any person who comes looking for a solution for this problem and is not that much familiar with coding.
Of course much respect to all the members who created and resolved this thread.
