Afaik If you do the EMM mod, even though the card will not lock, the mosc will be no different to a non updating fun card. Since You will have a non updating card the keys will have to manually updated when cc change them
There are alternatives. You could either download a rom 11 image which stays at Revision: RevB01 hence is auto updating and non locking
Or
Do not do the emm mod so card auto updates but it does lock and will need unlocking with an unlooper. But at least the box will carry on working so no need to unlock!
Note: There are also non locking rom 10 auto updating images around.
Nice tut crackerchalk!
