FAQ:
Q:why 17R cannot telnet ?
A:17R has no essential files for enabling telnet
Q:why I can't flash 27R (17R)?
A:Motorola has made some s**king restrictions to prevent users modify his firmware, even the stock ones are not so fit for any Z6. the bootloader version 03.CD works on 17R, and A3.C9 on 27R, others I dont know, you should try yourself. it's ok when the phone doesn't boot, that means your phone don't like this version, flash another one.
