Difference between z3x & z3x Pro box


I’m looking to buy Z3x box.From a reseller i saw normal z3x box,z3x easy jtag box and also Z3x Pro box.

AFAIK,z3x box is for service/software/imei repair box and easy jtag is for boot repair.

1.What does the Z3x pro box comes with?Is it both functions in 1 box?

2.I got a G920F with 6.1.It got no network problem.Baseband and IMEI is ok but customer sent to other technician before so maybe security damaged.I tried with other box but not done "Bypass MSL Error".Can this be solved with either original IMEI of the phone by security repair or Super IMEI?
