Panic log analysis - 1 to 3 crash-reboot /day

Hi,

I have a refurbished 1 year old iphone SE 2020. It keeps restarting randomly 1 to 3 times a day, sometimes while using it, sometimes making a call, sometimes unlocking it with touch ID, sometimes when the iphone is sleeping.

At some point i could not make a save with itunes (i could syncronise data like music and photos though), the memory could not be read nor written (maybe a separate issue).

I recently decided to wipe it clean to see if the issue persisted and here it goes again like before. The issue started to be annoying maybe 2 to 3 month after the purshase, but i did not care at that time, of course i should have reacted faster.

I am trying to find what the cause is before changing (if there is) a faulty component myself or telling the vendor he sold me a faulty product.

I tried the "idevice log analyser" from waynebonc, it doesnt find my logs while detecting the iphone on my PC so here i am.

I hope you can help me guys, thank you very much !

Well. First. Thanks for a collection of new panic types to add to my iPhone Kernel Panics page. It's still a bit of a work in progress, but sort of a passion project.

Secondly. The SEP panic. Sounds like bad news. The SEP is the Secure Enclave Processor. Which is basically a part of the CPU Which handles and houses all the secure data on the phone. Things like Face ID or Touch ID are most notably stored here. But that's not all. It's super important for proper iPhone boot and normal function.

I will have to do a bit more research since the other two panics are not ones I recognize. But honestly. This sounds like it is very likely an issue with your board.

In which case, if there is a warranty trying to get in touch with the vendor might be a better bet. But have a look at the iPhone Keeps Restarting page just to make sure you've covered your bases if you want to repair this yourself.
