The problem for new versions z3x software IMEI repair e1200R

Hi

I have problem problem for new versions z3x box Sam IMEI repair


Flash Mode:


Software version: 21.1


Waiting phone... detected COM20

Sending FDL... OK

Reconnecting phone... OK

Reading NV... OK

Checking NV... OK

IMEI Master: 024447774440452

Phone HW: MP 0.300

Product code:

Phone S/N: R21F87A4SE

Sending NV... OK

Repair done

Done with Samsung Tool PRO v.21.1


Phone not power on ! I need to install version 16 and repeat step


Normal mode: It shows with doing but it does not


Please improve it because I always want to do as older models need to
install the old version . Likewise, the new PRO does not do many i9300 ,
i9505 , etc. - I have to understate Z3x software .


Through these errors begin to regret the PRO bought and not another program
