I restored a PS4 backup e now the PSN games that I've purchased are locked

Hi guys.

I did a full backup restore in my PS4 but now the games that I purchased online from PS Store are locked. When I attempt to play them it asked me to buy them.

I probably need to sync with my PSN account. But I don't want to go online because I'm on 7.55.

Is there any way to unlock the games without going online? Although I know I can download FPKGs with the new 7.55 exploit, I would like to keep my original games because I don't want to lose my saves for them.

Thanks
