How to get skey for sl75?
midlet x65v5 (from comments works with some x75 phone) can`t be run
midlet x75v1, start and after enabling access to local files, generate java exception
midlet viper gsm, can be started, ask for access for serial port, and after while, says "java need data cable".
...prolific cable working on S-Gold phones only if you insert two resistors (10Kohms value) between pin 2 -> pin 5 and pin 2 -> pin 7 in the Lumberg slim connector.
BTW, use BsReader midlet and export ESN and HASH to papuautils. After use papuautils SKEY and Boot key calculation.
