I have tweaks from Willerz's list that I paid for or we're free on Iphone 5 7.0.4. Every time I go to install a new tweak off compatible list springboard crashes , I get the apple screen, and then I'm in safe mode with grey screen. I try to reboot from choices that safe mode offers to no avail. I then use respring tweak to respring and all is well. I'm just running into issues only when installing tweaks from Cydia. Is Cydia the culprit? Buggy?
