can you show how the current main branch fails ? when I try it seems to work fine:

[USB] chameleon --> hw slot list
 - Slot 1 data:
   HF: Empty - Mifare Classic 1k
   LF: hello - EM410X
[USB] chameleon --> hw slot delete -h
  -st number, --sense_type number
                        1 = LF, 2 = HF,
[USB] chameleon --> hw slot delete -s 1 -st 2
[USB] chameleon --> hw slot list
 - Slot 1 data:
   HF: Empty - Unknown
   LF: hello - EM410X

Now try to delete LF dump, it won't allow you

[doegox]

yes you can't delete the last sensetype, delete works only when both sensetypes are available.

[USB] chameleon --> hw slot list
 - Slot 1 data:
   HF: Empty - Mifare Classic 1k
   LF: hello - EM410X
[USB] chameleon --> hw slot delete -s 1 -st 1
[USB] chameleon --> hw slot list
 - Slot 1 data:
   HF: Empty - Mifare Classic 1k
   LF: hello - Unknown

[USB] chameleon --> hw slot delete -h Delete sense type data for a specific slot. The slot needs to have the other sense type correctly configured, otherwise an error will be thrown.

[Foxushka]

I don't see any point of this restriction. How we can clean whole slot without factory reset?

[doegox]

No idea, feel free to change it, but your fix doesn't seem adequate, it's not about HF/LF inversion.
