    I got uncover from tweakbox and jail broke my phone but after I installed a couple tweaks I went to open uncover and it said wasn’t verified but I did it when I first installed it. Then I went to verify it(again) and it said it needed an internet connection but I am connected to the internet. I’ve looked every and can’t find anything about this problem. Can anyone help me please???

    my phone unjailbreaks by itself overnight while charging, I wake to my phone being back to stock. Any recommendations ? …. Seriously ill never get like this while jailbroken with electra i always had to rejailbreak after 7 days if someone can help thanks guys!!!!!!

  9. Dylan Rosario

    Hugeeee question, because I literally can't find a genuine fix for this anywhere: Some of my preferences won't load into settings. I get an error saying it couldn't load the preference bundle. Is there a fix for that at all? In all my years of jailbreaking, I haven't experienced this until now and thus I'm lost.

    After I got the error where it couldn’t extract bootstrap, I did as you said got rejailbroken, but all my tweak are gone. Any way to get them all back without having to go and install every one of them again?

  11. Chris Slaughter

    EVERYONE! If you update “essentials on Cydia and see something like borne supremacy etc. DO NOT REMOVE THEM! I accidentally taped the “unsafe” removal and my phone crashed and would not hard reboot?. It went to the initial “hello” screen and would not open the phone?. I tried everything, but the only fix was updating to ios12.2. So don’t make my mistake?….. jailbroken phones are very sensitive ?

  12. Knut Melbye

    When I’m trying to install a tweak these two errors pops up:

    1. Failed to open package info file ‘/var/lib/dpkg/tmp.ci/control’ for reading: No such file or directory

    2. Sub-process /usr/libexec/cydia/cydo returned an error code (1)

    Please tell me how to fix these problems!?
    Thanks
