Hello everybody, So a few days ago I was installing a Tweak from Cydia on my phone and when it was done installing my phone froze. I rebooted my phone by holding the power and home button at same time and it got stuck on the apple logo. After that, I tried to reboot it a few times from redsnow but that also didnt work. Finally I tried to restore my phone with itunes but I got an error everytime. Error 1601, 1602, -50, 21 etc. I tried to do it in DFU mode, recovery mode, "normal" mode. But they all ended up failing. Is there anyone who can help me restore my Iphone??
