What did you do before?

Did you enter anything at uboot?

Does it show anything at all?

Nothing else was not doing at uboot before and after. At this time switch shown "0" at stack indicator and anithing at console. Before crashing switch was cyclically reloaded with creating crashing dumps.

with era all (not used that by myself) you have erased the complete flash ergo killed all existing firmware possible file structure.
So you need a recovery on uboot level (if that is still working) -> in this case you should see at least some miniboot/uboot related output on console.

If you have that:
With a recent uboot (6.4.3 if i remember correctly) you should try a usb recovery -> find a recognized usb stick:
Test at other running switch
"usb enable" should give you some output, "cd /uflash" and "ls" afterwards should show you files on the stick.

if you have that create a directory
/6850/certified
/6850/working
on the stick
create a file aossignature in root of usb

copy the img files in both /certified and working on usb stick.

insert stick and it should do a disaster recovery.
#####
If you do not see uboot/miniboot update:
You probably bricked your switch.. have it returned to alcatel (this is why you should not use uboot commands unless told so by support), i never used "erase" at uboot only "newfs" in miniboot.
