Now that you have PSVIMGTOOL frontend installed, open it up and pick backup manager, then unsign & extract, then last is system backup.

Once the backup is made you are going to install PSVIMGTOOL frontend and use it to decrypted the system back up. In this post, I will show you how to use psvimgtool to extract the app.db file and modify it for custom themes to work on newer FW.įirst, you are going to make a full system backup with cma or qcma ( I prefer qcma) on the PC. We’ve been getting quite a few request on how to install custom theme on FW3.63 or 3.65 and since the release of psvimgtools there not really a clear guide on how to install them.
