iPhone 6(S)/Plus Cant restore deleted Messages

[snadge]

I have an iPhone6S - someone has deleted very important court case documents, I have tried a few "pay to display" programs which simply show all the current TXTs (and maybe 1 or 2 that weren't there but irrelevant

can someone advise on what's best to use?

I tried to use an Un-Delete software but the drive doesn't show in windows My Computer, it shows as a phone that you have to click on to get access to the storage - these un-delete programs will only pick up true local drives in My Computer

If you’ve got a previous backup then you can restore back to that. Don’t think there are any other option.

there are many programs that scan ready to-be-written blocks - the unfortunate thing is he continued, to use the phone several months later which meant the data is well gone!
nothing will get that back
