I have iOS 11.2.6. Using u3tools to install jailbreak app. It installed Electra instead of unc0ver :((
So I jailbreak using Electra and I can open Cydia, but most of the tweaks not working (like the theme etc, but I can open cracked apps) and I cant install any cracked apps. And now my Cydia is gone -__-
edit: managed to restore cydia by going to terminal and run uicache. But, Cydia is buggy. Ton of tweaks need to be updated cause of that ugly Sileo, and cant be updated. It require ton of remove and stuff, which resulting more buggy jailbreak. So i cant install any tweak because it require me to do those things. Infinite loops... And now, Electra always stuck at stage 2, not succesfully jailbreak and give me black display (only on Electra)
Just gonna wait for CydiaImpactor or other online sideload to works so I can get back into unc0ver and wipe out Electra again. (I used electra before uncover, and its so buggy for me, even cant add source repo on sileo)
