Hi together,
good news & bad news....

Scope DS2072a FW 03. SP1, HW2.0
Memory dump with: echo :SYST:UTIL:READ? 15441920,13262848 | ncat -i 1 SCOPE_ADDRESS_HERE 5555 > DS2072A_sdram.bin
works fine. 12,9MB.

rigup DS2072A DS2072A_sdram.bin > opt.txt
works also fine and generates 4 different keys (only all options, 100MHz full option, 200 & 300) and I try all but they sems not to fit.
PS: also rigup scan DS2072A_sdram.bin > ec_decoded.txt works also fine an generates valid entries

BUT entering the key over:
a) Scope directly = 0 reaction
b) over Ultra Sigma SCPI command ":SYSTem:OPTion:INSTall key" = 0 reaction
c) over Ncat via LAN "echo :SYST:OPT:INSTALL A_KEY_FROM_OPTIONS_WITHOUT_DASHES | ncat -i 1 SCOPE_ADDRESS_HERE 5555" = also 0 reaction

Any ideas/hints why it fails?
Update: Scope was blocked by to many false tries to enter unknown Options. After factory reset (multipress left gray button #6 multiple during booting) and retry to enter generated keys

IT works!
