Though there is just a serial # in there (I changed the last numbers into '0' as probably not important).
This Zip also includes the calibration data. It shows that indeed the calibration borders are "2" and not "6", thus there should be no problem by using the 3055x-e firmware.

How can you get filesystem access and/or telnet on the dmm?

I've tested post #14 from linked thread on a SDM3045X with latest v5.01.01.07R1, with a 4GB FAT32 clean USB stick, but couldn't get past step 2 - any TCP connection on standard telnet port 23 is refused, while on the other open ports (111, 732, 5025) they drop instantly.
Any hints are greatly appreciated.

There is also the info on how to backup the calibration data.

Ok, thanks.
Tried the attached FW file, but any flashing attempts results in 'update failed'... Are there any special steps to be taken for flashing - especially since the unit may see it as a version downgrade?
