I haven't had an
y success of popping the rom102 rev242 with any script at all.
I was able to pop the rom102 rev103 without any issue. But, I just can pop the rev242 with any resistor pot setting.

Any suggesting?
I have used winexplorer, nagramaster..
I got a good atr and it does read the rev. if insert in iso reader.

I think that's a rev106 and you can try this:

Rebel Serf 102 rev108_244 Unlocker_Reader
*NOTE* Works with revs 106 up to 108

Use 4619 chips.
Dip 1 (on) all others off for powersync
not sure on Mikobu N2
Set the trimpot 215-257ohms
with 9v power supply and newRS flash
