Hello everyone, I hope someone can help me, I tried to revert to OEM firmware on an MX5300, I followed this guide https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=70fd815e57dc98cef88828faa5ce71717540e99e number 4, but when I restart the computer it no longer starts, it only stays with the LED on, I opened it to see if I can connect it via serial. I can't read it, but I can't type it or stop the boot, to try to flash it using a tftp server, I've done it with mr7350 and mx4200 I think it's similar, but I can't stop the boot, I don't know if the serial connection is ok or what's going on, or some other method to recover it
This is what it shows on the console
