I have one of these rare machines with 4 hash plates, the problem came when one of these went away, the firmware of my machine does not have an event log, so I tried to update the software to an original one. The control board is the G19 model without sd reader, after updating the control board it has died, it only turns on a small red led marked on the board as D1, if you press the reset button it turns off and a led turns on green D10 and the fans go up to 100% but in no case do the front lights or the network card turn on. I have tried pressing the ip button, both at the same time and the reset button for several minutes, but it does nothing new. I don't know how to install a new firmware, the board has several pins, a row called J25 and another called J26, maybe by bridging one of them the firmware will be reset, I have also thought about soldering an sd reader, I don't know if any of them have any idea of ​​how I can recover the plate, I need help, thanks

Hello friend, I introduce myself, I am Jose from Spain.
I have miner innsilicon or dragonmint or aladdin t1, well it is the same as the t1 but it mounts 4 hashboard  , the fact is that I have tried to update and I must have installed the wrong firmware and now it only lights up the red led D1 of the control plate, none of the headlights and the network does not work. I have tried to press the button Ip report, reset and both at the same time and nothing. The control board model is G19 without a card reader. There are several pins on the card, does anyone know if you can connect a usb input or sd reader or is there a way to reinstall the firmware, since right now I can't connect via network
