Hi, after all I didn't need to change rom, with Mauro V8 I've manage it to work, Its exactly that problem that I told you in the beginning, the Ground wire needs to be connected to the fifth pin (in normal cable Classe B)...
Here is the photo of the finished work, and yes... OTG in G615 works, you only need a connection for a external power supply!
Well it's a bit of a mess, but I'm going to explain why all the colours (female USB) and all the cables... I didn't want to ruin any new cables that I have, so I took old cables and a hub with 4 female USB ports, and built this one that almost seems Optimus Prime
The OTG cable, I've done it from a Nokia Data/charging cables, destroying it's armor inside the strong rubber that covers it and with meticulous work, very carefully, I took (with a scalpel) the inside cover which is some kind a type of a hard/rigid white glue, colored like silicon, and found the empty pin and the Ground (black) one and connected them through a little piece of wire from a old usb cable, then taped it with black insulating tape...
This was the hard part, next followed the easy but labored one, since I didn't want to mess up none of my cables that have, male to female usb ports, I needed to figured out how to built an alternative cable to power up the OTG cable, since our mobile needs it due to is lack of powering these kind of cables (kernel issue).
Two cables needed to this one (old ones of course), and three USB female ports from a hub that I didn't used, and patience...
A Samsung cable was used for powering the other cables, so it can be connected trough an AC USB 5V adapter or directly connected to a computer (red and black wire were the only used), the rest of the connections, data/power ones, were made trough a cable that didn't had any brand but however it seemed the better one (quality of the inside thread), resuming, it was only need to follow the schemes that already were posted... Finally, in the purple door is were the external peripheral devices connect. I've also made the blue and orange connection to maintain the male USB port to try latter an original OTG cable
And after the trial...
, there it was, in ES explorer the USB file located in Mount it opened and showed it the files inside!!!
Howwwwwwwwwww awesome!!! And after that I've connected a wireless mouse and it also worked!!! Cool!!!
Well this experience was mainly done to experience the capabilities of this phone since I do not see much use for this type of use in a device of this size, but the little black with a white frame cursor in the screen of this device is strangely pleasant!
I Hope that this post becomes helpful to someone.
Oh and I've stripped so much f******* wires (with an lighter) that I still have my fingers sore...
