English is not the OP's native language, so that would explain why it isn't the easiest to read.
To answer the OP's quesions...
1) If you already wiped with JLCmder or BBSAK, then you have already lost your contacts and calendar appointments. It is most likely too late to do a backup of your device.
2)
What to do next if Jl Cmder will not connect and wipe - BlackBerryFAQ (I am glad I am not a female)
3) Once the device is completely wiped with a 507 error on the screen, you should then be able to load the OS onto your device.
