Update:
As I've promised, here is my progression update on flashing the firmware on my miner:
I was able to get hold of my miner, the require tools-sd card,reader,etc. After disassembling it I've found out that my miner has a CRT0302 ""double board", which means, according the original site
https://support.bitmain.com/hc/en-us/articles/360019493654-S9-series-S9-S9i-S9j-S9-Hydro-Control-Board-Program-Recovery that I need to shortcircuit the board.
Unfortunately , the official site doesn't do a very clear job(or just i dont understand it,but it doesnt really matter from my perspective

) of what should be connected to what out of the 4 different "pins". If someone could point it out to me I'd really appreciate it!
