Password doesn't work

[Yessos]

I upgraded from stock firmware using lede-17.01.4-ramips-mt7620-u35wf-sysupgrade.bin as it says in the instruction, but upon login I met with the following message: Non of the usual passwords work like "password", "root", "12345678" or empty. I am completely locked out and reset button now does nothing for some reason. @arvati please help.

What I did was: 1) connect lan cable directly between Kimax device and my usb adatper (http://www.tecknet.co.uk/ul699g.html) but keeping the adapter disconnetd from my macbook pro 2) connect the usb lan adapter to macbook just after Kimax red led starts to blink 3) both Kimax device leds start to blink really fast and stays like that 4) now the device is in failsafe mode and you can access it as described above Hope these can help you

It doesnt work for me... I plug this lan adapter just in time when red light starts to blink and like you sayd booth lights start to blink fast but it tooks only about 2 secs and stops...

[FilippoIOVINE]

I assure you I made this test several times and it always worked. I kept the cable conneted to the usb adapter and conneted to my mac book pro just when first red light started to blink. Have you tried to set static IP address of lan adapter to 192.168.1.100 (and gateway to 192.168.1.1) before doing that?

I was looking for an easier place to solder the Tx/Rx, and I found that they're exposed on one of the ribbon cables as well. But strangely, I couldn't find them anywhere on the other board that the cables connect to.

I suspect they might be exposed on some USB or ethernet pins, but something else has to be configured first. Does anyone know?

[servas35]

Sorry I am back again, soldered successfully with shaky hands however connection still not working. Have tried to swap TX and RX on adapter

Setup COM port and speed on Device Manager, COM3 (and later 16) and Speed 56700 PuTTY does not show anything except for green cursor. Won't let me type anything (maybe because connection never established.

Any idea what I might be doing wrong? Should I try to connect the TX wire on rest of the 3 solders? Also, DO i need to attach board's connections flex with the rest of the device?

what happened to the photo I was able to log in as root

Still having this problem. No wifi AP at all. At boot it responds to ping at 192.168.1.1 on ethernet for about 9 seconds, but doesn't accept connections on ssh, telnet, or http. Hitting reset button at various times doesn't make any difference.

Strange behaviour if I plug in the USB 3 cable to my computer. The ethernet interface goes up and down repeatedly and the wifi LED is on extremely dim. Still, no way to recover.

It seems there are a couple of hardware versions, I have one with green boards and was unable to access it.

I just went into failsafe and ran mtd -r erase rootfs_data and I was then able to use it normally, including USB.

[RenaKunisaki]

Is there a way to issue that command on a bricked device? Last time I tried soldering those test points I destroyed the board.

If you can re-flash SPI, you can re-flash back to stock with this SPI dump. U35WF.zip

I followed these similar instructions to dump/restore it using a RPi. https://www.reddit.com/r/openwrt/comments/dfuc9y/comment/f8xpdnu/?context=3
