Help/Support Cydia gone after reboot

[Bezerkey 0 11]

I have freshly jailbroken my ios 10.2 iphone 6s and i rebooted it since a tweak wouldnt work. Now cydia crashes whenever i start it and all my tweaks are gone. Is there any way to fix this without using a computer? I wont have acess to one for like 20h

1) Press and hold the Power and Home buttons for 10 seconds until your device shuts off and restarts itself.

2) While the device is booting back up (when you see the screen with the Apple logo), press and hold the Volume Up button until you see your Lock screen.

At this point, you should now have access to your device again. Keep in mind that because you’re in No Susbtrate Mode, none of your Cydia Substrate-based jailbreak tweaks will function and their settings will be missing from the Settings app.

 

Now is your chance to open the Cydia app and uninstall the tweak that was causing your boot loop.

I had the same problem. To solve this, You delete the Yalu gray icon from your IPhone and then reinstall it using Cydia Impactor. After that, keep attempting to re-jailbreak until Cydia comes back on.

Also note (not sure if you know this) but Yalu is a tethered jailbreak meaning you lose your jailbreak every time you reboot henceforth you must rerun Yalu after each reboot to get your jailbreak back allowing you to go into Cydia also because your phone reboots into safe mode it will never actually let you into safe mode cause you lose jailbreak upon reboot at least for me whenever I tried rebooting into safe mode it would just reboot again back to normal iOS as for deleting the tweak if you can't manage to do that your only option left is to restore before apple stops signing 10.2 and re jailbreak again best of luck to you OP!
