Hello! I have a WR740N V4.23 with the AR9331 microcontroller, the ESMT M13s2561616A RAM and S25FL032P flash

I was checking voltage with my multimeter and I think I short-circuited the flash or something

When I turn it on, only the power led glows and i get 1,7 volts on the last 2 leds of the right

I removed the flash from the board and I get the same problem, so I think the flash is the problem
I cant get serial access aswell (as far as i know it's a software feature)

Is there any way to solder a SD card and boot the system from  there?

Thanks in advance and sorry for any mispelling
