Unbricking MediaTek MT6580 By shorting KCOLO pin to GND - Android Q&A, Help & Troubleshooting

Hello, I did the worst thing possible on one of my devices which was formatting all + flashing a wrong firmware and a bad preloader. Therefore my phone isnt even recognized when i plug it in.
I wanted to try wiring GND to the KCOLO pin cause it supposedly forces a usb connection and therefore I could reflash my phone. However, not all pins on my phone's motherboard are labeled. I took a screenshot, can anyone tell me where I should connect GND to? I cant find the KCOLO pin.

[Q] Charging Port?

So, my S2's charging port is broken, I ordered new usb port for it. I got the usb port, I disassembled the phone and noticed it is impossible to change, so I ordered Dock Connector Charging Port Flex Cable Ribbon.
How can I change it?
Is it hard to do?
Can I easily break something else?
It looks like this :

Sorry for horribly written thread, I'm writing this from my phone.
Fairly easy to do & you're halfway there assuming you've ordered the correct part. KeithRoss39 has a guide in General (not stickied; search for 'replacing USB charger board') which has all the info you need to get it done, and he's the expert on these things here.

By my guess, GND at pin number 1 after contacting watch body using a multimeter. CMIIW.
Thanks for your help.
Just checked, the bottom pin, #5 in your pic is where the +5 comes from on the cradle

Strange RK3188 board, drivers problem.

Hello,
I'm working in Digital Signage company. We bought ultra-wide displays (1366x70, 19:1) with android board. The problem is that we want to install own software on this screens but display shows only 70px of top side of android. I think that LCD controller is set on 1366x768.
I can't connect to board via external usb ports but there is two USBs on board (OTG and USB1). I made a cable for connectors but Windows can't recognize this device.
Could anyone tell me is that some way to get to this players?
