Messed up my CC3D

Hi, I have a non-working OpenPilot CC3D and I think I messed it up myself. I want to get to the depth of the problem and solve it. I do have a Brain, a Seppuku (dronin) and a couple of Naze32 REV6 Full version boards around but they are all in use. The point is I had installed BetaFlight on it then I wanted to switch to dronin (It's amazing, try it out) I couldn't figure it out so I accidentally flashed with CC3D-OPBL in frustration and I regretted that immediately (even though cheap it's a reliable board) I tried a lot but I cant connect to the STM32 through the MainPort or any other port, I even tried bridging the ExOR gate between the microprocessor and the MainPort but it still gives an error. I want the board working (Its good as a dummy board, Why won't it be? Its just 10$) so, I would really appreciate any help. Please dont suggest me to buy another I am not going to do that.

Good luck, CC3D doesn't have bootloader pads so it's a complicated process to get it into DFU mode and reflash the firmware. There are videos on Youtube that show how to do this.

Well from what I have observed, you don't need to be in the DFU mode to flash the firmware, if you have CF of BF on it you can just flash it with an FTDI adapter connected to the MainPort and enabling the main port.(It has worked for me all along). I don't think that it is booting up at all since it is the wrong firmware that is flashed. The light is solid green. The CF flashing software says it expected something else (something like 120 instead of 100). I think I will be able to do it with a St-Link V2 adapter but I don't have one. And actually, I couldn't find any YouTube videos regarding this problem pleas post them if you do.

I tried doing that. But its a really messed up situation.
It still gives the same error. And I am not sure if it gets into DFU mode because the green light is always solid. And blue is not starting at all.
