Before Installing new Japhar sim

Hello
I have a little question
I am in the process to get a japhar nc3 for a dm800HDse V2 (clone) running sim 2.2 and ssl 88a with second stage r89 installed .
In the tutorial, it is mentioned to install secondstage-dm800sev2_allsim.rar with "original" sim before replacing.
Is it mandatory to do that or being on 88a(89) is good enough ?

Can I back up my actual second stage before flashing with yours ?

Thank you for the support

You can flash the ALLSIM SSL or the SSL88J from Japhar. In your case it will give the same results.

It's IS mandatory to flash the SSL first, before replacing the SIM. You can try to replace the sim without flashing the SSL and you will see that you will fall on NO CA ERROR message if you do that way. So if you want to do all smoothly, do as explained in the Tutorial.
