Data recovery from a SGH-p520 Giorgio ****** GSM

[bobfalcon]

Hello to all of you!
I hope anyone can give me some advice on this one...
Long story short: I need to recover some deleted pictures on a SGH-P520 ****** phone.
I already tried things like Wondershare, Recuva etc, but there are a few hurdles that make it hard for me and left me clueless....
For instance, Windows 11 gives a USB device error when i connect the phone.
Windows 10 has issues with executing any ancient samsung software (kies, pc studio) i tried but it does see the phone as a connected media device, but does not see root or internal storage, nor gives the phone a drive letter. Windows 7 and vista did run PC studio which gave an update error. It tries to connect to a Samsung update server but that servers do probably not exist anymore. With PC studio i can see what files are still on there but windows still won't assign drive letters which i needed for the recovery software i tried. i did find some program that could assign a letter to it but that did not fool the recovery programs which simply just ignored the phone. I learned that the phone storage is NAND and that it works different than FAT, exFAT, Fat32 etc. I also learned that you can do a full system backup to pc with later versions of PC Studio but those don't work with the phone, which could be caused by the phone´s firmware which never seems to have been updated from stock.... I was hoping that i could recover files from a full system backup.... if only i could get it on my pc..... The pictures that were deleted from the internal phone storage were very important and just need to be un-deleted. No new files were written to the storage so it must be possible you would say.... Any tips, hints, software or other type of help/support is higly appreciated. I had contact with some guy at Sammobile but there's no living soul left there that knows about the firmware or pc softwares that can be used.

Thanks, in advance!

Kind regards, Bob
