Ubiquiti Nano LocoM2. Not working, help

[SoporteHR]

Hi all

Receive a warm greeting

I have a LocoM2 unit.

I presume that the firmware is corrupted since when turning on the computer it does not do anything.

¿Someone will have the original dump version of this computer?

I downloaded a firmware from the official page, but it did not work. Now turn on some LEDs but does not respond.

Record the flash with the CH341 programmer, since it was impossible to connect via LAN / TFTP.

LocoM2
Board: FR494 V-0 / E88551
Flash Chip: Winbond 25064CVF1G

Thanks

usually these things are purchased in pairs, also 2 of them at the same time. See if you can get the other unit, factory reset it, then copy the content. I haven't seen one that had corrupted firmware. If the winbond is good, I highly doubt the firmware is corrupt.
what happens if you press the reset button? Make sure that button is good and not jammed (don't ask, I've seen that).

Hi.

Thank you very much for your answer.

I do not have the other unit, they only gave me this as a gift and for replacement, since it is practically dead.

Turn on but there is no connection to the LAN. The LEDs do not respond as it should, nor does it respond to RESET procedures. Neither factory reset. That's why I think it's a firmware or memory problem.

Thank you.

There are 2 different firmware's available for that LocoM2. Apparently there are 2 different boards. An XM and a XW board, each have their own firmware. Probe around the LAN port with an oscilloscope. Some LAN connectors have magnetics inside, or my best guess is the LAN chip itself is bad and needs replacing. Look at this example for an Atheros 7240: http://www.lan23.ru/forum/attachment...0&d=1502374718

Simply connect a console (UART/whatever) cable and see how far it boots.

CPU are bad
Change AR7240 or 7241 and working again.
