Help with my infinitely booting iPhone

[CptSalty11]

I know this isn't necessarily the website for this question, but I need help with fixing the boot loop my iPhone 6 is experiencing. For around 6 months, I have had my iPhone 6 jail-broken with the yalu102 jailbreak. Since apps from the app store weren't downloading, I looked for any version of appsync I could find, and downloaded Appsync Unified from the insaniely repo. When doing the required respring, my phone stayed re-springing indefinitely, and so I hard reboot it but then that cause it to be stuck on the apple logo. Find my iPhone erase isn't working, and I don't want to restore and update my phone through iTunes. I don't care if I loose all my data on it as long as I stay on 10.2.

It's an iPhone. There aren't really any diagnostics you can perform if it isn't booting. You need to put it into recovery mode and let iTunes perform a clean install then restore from a backup, start fresh or perform a new jailbreak.

Although it's been awhile since I fooled around with jailbreaking. Apple finally added some feature I wanted in iOS 5 or 6 and had no more reason to Jailbreak. Anyways, you may have to enter DFU mode to recover it.

Flash your phone with a third party software and then restore your backup from iTunes, you can perform a jailbreak later on.
