There was an error loading this photo, cannot load photo
Yesterday I tried to transfer all the photos from my iphone 12 camera roll to my mac. I failed to do so (it could not read my phone properly, I suppose due to a worn out cable). After that, all the photos and videos (6500 thousand of them) on my iphone became blurry - so saved in lower quality, have an exclamation point on them and I can't seem to access them any way. I must mention, iCloud was never enabled on my phone or on my mac, I don't use that for these devices. All of the tips on retrieving my photos I found online are related to iCloud, but that is not the case here. I tried: updating from ios 14 to the newest one (15.4.1), reset all the settings of the phone to factory settings, and also deleted some stuff to free up 2,99 GB of space. None of those things helped. All the photos I try to take after the failed transfer are taken in normal quality and I can access them without an issue. The problem are all the photos prior to that (so my whole camera roll). I'm going crazy over here, please help.
Oh and when I installed the new ios (which took more than an hour to do via my mac) there was a backup made, and that is the only backup I have. The backup size is 30 GB and my iphone's memory is 65 gb. Does that mean all my photos are lost? Because on my iphone it still says 62 out of 65 GB are full.
Please help :(
iPhone 12, iOS 15
