Help/Support Ipad 3,1 (jailbroken) - recoverymode loop

[wannabepear 3]

Jailbroken ipad 3,1 running ios 9.3.5.
I copied some game saves into a folder which i don't remember (probably i shouldn't have to in first place).
at this point my ipad went in a rebooting loop so i searched and i found this software that claims to be able to fix it so i downloaded it and, following their hints, clicked "enter recovery mode" and it entered in recovery mode but it never exited.
now my ipad is in a state of permanent recovery mode (power on, loads apple logo, enter recovery mode cable image and connect to itunes image ) and it is not recognized from itunes, nor from device manager.
When i attach the usb cable to it nothing happens, if i attach it to the wall while powered off it still go in recovery mode.
I have no idea of what to do honestly.

Put your device into DFU mode and restore with iTunes

Save files doesn't cause it. You probably installed incompatible jailbreak tweak on your device

i'll try, but correct me if i'm wrong, almost every jailbreak hack nowdays is arm64 only and this one is a very old armv7 worth no more than 30$ on ebay i found a nice offer for an ipad air 2 which is an arm64 and i'm probably going for it

edit 1:

i tried multiple times hard reset (power button + home and release power but its not working, the ipad is not recognized from the pc) i even changed cables and a different pc but it didn't help.
