If youre sure you have a v500 you should flash recovery via flashify
Else you cant flash anything belonging to v500 through recovery since your recovery makes sure it is a v510 build before flashing it
Ok so here it is, it was a pain in the $%$&"#.
First I installed TWRP 2.7.1 and it didn't work because the problem was this.
If you updated you LG Gpad over air then after installing any recovery software the device recognize V500 device as V510... which is LG's fault.
If you wanna read more about his this is it:

Then I was thinking of using LG Mobile support tool to come back to original Rom, and then try again, but that was out of the question...
but if you want to know this here you go:

So what I did (most of it my friend helped me) is that when your LG is recognized as V510 or Palman (and you know you have V500), you need to edit updater-script file that is in Mahdi Rom... here:
mahdi-2.7-v500-20140805.zip\META-INF\com\google\android
Why you need to do that is because it's recognize V500 device as V510, so when you edit that line, it won't even check which device that is.
Now the TWRP still didn't worked, nor 2.7.1, nor 2.6.3
So I tried that with Philz, and I also edited Philz file (as I can remember) for recognition the device, It worked.
Now that I was on Philz recovery I installed edited Mahdi Rom, and everything works.
Hope you guys understand what I went through...
