How To TFTP EdgeRouterPRO / ER-PRO-8 / EdgeMAX

I have 3 EdgeRouters in my backbone , one of them began presenting crashes, take down bgp session and delay at startup.

I notice that when this occurs the LEDs of the interfaces are off , requiring one or more reboots followed to normalize .

In LOG equipment could identify error KERNEL / squashfs .

SQUASHFS (kernel: SQUASHFS error: Unable to read directory block [426d907:1f69]).Anyone know how to make a clean install ? Reinstalling EdgeRouter again ?

The Forum found solutions for ER- Lite , ER- POE and ER- X, but for ER- PRO have not found anything yet.

P.S : Sorry for by google.com English
