[Em3rg3ncy]

Okay, I can't launch Unc0ver at all, it just crashes at startup

When I try to launch the Unc0ver app, it just crashes.

• iOS Version: 11.4.1
• iOS Device: iPad Air 2
• unc0ver Version: 3.5.6

Place an "x" between the brackets if true:

• [ ] this is a bug others will be able to reproduce
• [ ] this issue is present with all tweaks uninstalled(except for default packages) or disabled
• [ ] this issue is present after a rootfs restore
• [x] this issue is present on the latest version of unc0ver

I tried to re-installed via Cydia Impactor. Use older version like 3.5.5. None of them worked

This exact same version was working but after reinstalling it (bc it expired) it wont open, i tried deleting the appid and certificate but nothing... Gonna try an older version like 3.5.4 and see if it works

Reset like reinstalling iOS?
I tried cleaning the RootFS with Chimera to see if it fixes it with no luck. I ended up jailbreaking my iPad with chimera and installing cydia for chimera...

Well, i upgraded to iOS Version 12.4 and Installed unc0ver but this didn't worked for me (App Crashes on Launch) so i did a reset in Settings > General > Reset > Erase All Content and Settings.
but i have no idea if this can cause any damage to your iPhone.. i did this once with Electra and almost Bricked my iPhone. Create a Backup before proceeding.

• This problem seems to have nothing to do with Unc0ver.
• There are some problem with Apple's certificate server. Therefore Cydia Impactor and Reprovision can't sign Unc0ver successful.
• Use enterprise root certificate can solve this.

I download Unc0ver from https://app.ignition.fun/ (in Jailbreaks -> Unc0ver(Official)) and it is working. Unc0ver no longer crashes and Jailbreaks success.

Hello, first of all.
Your solution fixed the problem perfectly for me! Thank you very much!
But at this moment I'm worried that do I have to resign the app after 7 days?
Even though I downloaded it directly from the Safari browser?

Same here.
iPhone SE on 12.4
Unc0ver 3.5.6 or 3.5.2

What I've tried and failed: (between every step there was a hard reset holding down home+sleep)

• installing 3.5.6 using jailbreaks.fun -> stays greyed out
• installing 3.5.6 using app.ignition.fun -> stays greyed out
• installing 3.5.6 using cydia impactor 0.9.52 and my own apple id (basic apple id, not a dev) -> instant crash
• installing 3.5.2 using cydia impactor 0.9.52 and my own apple id -> instant crash
• in cydia impactor [Xcode]->[Delete App ID] then [Xcode]->[Revoke Certificates], after these two succeeded, I tried once installing 3.5.6 again -> instant crash
  The crash looks the same as OP youtube video (https://youtu.be/v9O1oZEWKy0)

What I did however: in cydia impactor I had opened [Device]->[Watch Log...] and saved the output of the crash.

Apple is unsigning ignition apps but they're currently re-signing them so you'll have to wait a bit

[romestylez]

Same here. Im using newest unc0ver and also tried older versions. Tried two different Apple IDs (revoked all Apps/Certs). Also tried ignition etc but its always greyed out and not finishing installation.
