Flashed modified firmware, laptop not booting anymore

It worked!!!
Here is what I have done, Yesterday I soldered two wires to JECDB port to connect to UART, but I didn’t get any output because the USB cable was broken (bruh). Then while moving everything I ripped off the pad for TX (bruh x2)
Today, using continuity mode on a multimeter, I found out that the TX pin was also on the JSWDB port (the one with 12 pins) on pin 4 starting from the left.
So I soldered the wires run your commands and then boom the computer booted.
