I had been thinking about the '200 OK' response code, so when I saw 300, 200 and 204 together, I looked up what 204 meant.


How will you detect a wifi hotspot landing page without a www host?
That! Is a good find.
Should be fixable by patching out those cmp instructions directly in the binary.

I think replacing

Code:
 CMP     R7, #204
BNE     loc_22144
With

Code:
MOV r0, r0  (0xe1a00000)
which is NOP should work, and no need for the service then.
