[HELP] Bootloop of Death

Hello.

Tody i woke up in the Night because of the Respring Loop. Before i went sleep, i turned my iPhone in Airplane Mode and was in the Jailbroken Mode. I made a Hard Reset und let my iPhone boot. After 2-3 Minutes my iPhone reboot itself. This Cycle goes on. My iPhone is in a full bootloop of Death even in non jailbroken mode.

Is there anything that i can do to fix the Bootloop? I Dont care about my iOS 9.3.3 Jailbreak but i dont have any saved data on iCloud / Computer. my Data is important for me. Is there any Way, that i can save all my Data?

Hope someone Can help me? i Will donate 10 Euro to someone, who can help me, to get out of the Bootloop of Death or save all my data.

Big Thanks in Advance. Greetings, Lukas
