Thanks for all your help and hard work. I got a few questions I hope you will help.
In PRFCreator_v1.0, assuming this is what you used, did you make your zip with Legacy Mode checked or unchecked? Or does it matter?
I made my own prerooted 23.4.A.1.200_R4C zip for my SGP512 US tablet basically how you explain except I didn’t know about the Legacy Mode.
I also signed my zip which worked before so I did it again, but on the PRFCreator thread everyone says don’t sign, so I was curious what you do?
I only do this stuff a couple times a year so I get foggy about the procedure, especially when the device has been heavily used with all sorts of stuff added and customized over time.
So I already had prerooted 23.1.A.1.28, SuperSU-v2.46, and dualrecovery2.8.15 installed on device since the beginning, per your instructions way back when.
And I know how to flash my new prerooted 23.4.A.1.200_R4C zip, assuming I made it correctly with the Legacy Mode thing, but what I don’t know is about the backups and the wiping and when to do them and if I need to do them, etc….
Also, will flashing the zip cause me to lose all the extra stuff I've done to the tablet or installed apps, customizes, etc…or do I use titanium backup before flashing and then restore it after flashing or some mix of these events? Or one of the recovery backups if I make a new one before flashing? Thanks again for the help.
