Help/Support Unc0ver 11.4.1 bootstrap extract error

RyNx_APoLLo · March 1, 2019

Hello I’m on an iPhone 8(red edition) with iOS 11.4.1, jailbroken with Electra. I am trying to switch to unc0ver but I get 2 errors. After my phone reboot about 2-4 times, it says “fatal error, extracting bootstrap failed”, then it says my device is jailbroken and I can open cydia but I get the first copy of cydia. If I go into Cydia its like a dead copy, I can’t install it uninstall anything. Please do anybody have a fix to this?

Thx but I just upgraded to 12.1.4 and then downgraded to 12.1.3b3 which flashed all my files then allowed my to jailbreak. I tried using all those methods to remove jailbreak but they don’t work for my phone. Also @MeSailesh7 what version do u recommend for jailbreak?

I Myself I am on 12.1.1 rightnow using unc0ver jailbreak and it works well and stable.

and depending on your device if you’re are using device lower then A8X then you should use unc0ver upper then b36 version but as of now there isn’t full jailbreak for those device and A12 there isn’t any jailbreak while as if your device is A8x to A11 then I would recommend using unc0ver b36 as it solves one of the major bugs on unc0ver.

Edit: IOS 12.1.3 b3 Or 12.1.1 b3 ? You can only jailbreak upto 12.1.2

Yeah, thx. I have the A11 chip. I was wonder because my device is red which is limited edition it have a little bit different security than the regular 8. The way the ps3 and special ps3 is. But I might flash again and downgrade to 12.1.1 instead if the beta version. Thx.
