CID 49 is better cuz it's easier to customize, CID means the security level of the phone, the higher the CID the harder to customize. now that your phones EROM CID is 52 it's hard to downgrade back to CID 49. Try to customize your phone with XS++ v1.5, it has CID 52 support
XS++ has CID51/52 only flash support but no customization!You can flash MAIN firmware and filesystem but without finalization.

you are right, the I guess CID 51/52 can be finalized only with a paid service like DaVinci.
ster1357 - you could try to talk to the DaVinci team and ask them if they can downgrade CID.
