Respring Loop

Hey guys,

Since yesterday around 2pm my iphone 6 with ios 11.2.5 (latest version), started out of nowhere respring every 10 secs or less and then asked me to put my passcode to access the phone, i proceeded as normal, backed up all my data and then i restored my phone through iTunes, it took me a few hours to do it but it worked for me the rest of the day.

Today, around the same hour as yesterday, it started all over again but this time it got even worse, it is not just the respring every 10 secs, now its on a respring loop, cant access my phone.. Can anyone please help me?
