(OK you need XP  .net and nokia basic utils)
Need to sign sis files 

cannot get a symbian account (surprise surprise...)

This will work on 9.1 9.2 phones  ie n95 21.0.016

if it only works first time recopy these files to there locations 

0000001
key.key
cert.cer

or just re do the procedure in the install docs

!!!!!!!! if xplor.sis file wont install on your phone try drjukka ybrowser!!!!

Hack perms make sure the com port is correct it can change when you reconnect!!!!


Have fun 30 years of cert life
