Device freezing after installing new substrate

After installing new cydia substrate i reboot and rejailbroke my device. After sometimes my device got frozen and i was forced to hard reboot my device. After reboot, i rejailbroke my device and after sometimes my device froze again. I used restore rootfs but the freezing issue is still not fixed.

I am using iPhone 6, iOS 11.3.1 Unc0ver v2.1.0 (latest one)

I also found some users with same issue. It mostly happening with older devices.

[iOS 11+12] Please fix cydia-no-network error for China devices

Hi, you may not know the fact that iOS asks network permission for an app when it get the first launch on all China device models. Network for that app is not available until user grant the permission.

However, with some reason, after the initial JB, Cydia just get no chance to show that alert. Users can not even find Cydia item in Preferences app. As a result, Cydia just not work after the initial JB.

A workaround is to delete some Network Extensions files or using a VPN to bypass, but that's very tricky and dirty.

The best method is to call AppWirelessDataUsageManager(link to /System/Library/PrivateFrameworks/Preferences.framework/Preferences) for Cydia explicitly.

code for iOS 11:

NSString *cydiaBundleId = @"com.saurik.Cydia";
[AppWirelessDataUsageManager setAppWirelessDataOption:[NSNumber numberWithInt:3] 
                                      forBundleIdentifier:cydiaBundleId completionHandler:nil];
[AppWirelessDataUsageManager setAppCellularDataEnabled:[NSNumber numberWithInt:1] 
                                       forBundleIdentifier:cydiaBundleId completionHandler:nil];

code for iOS 12:

        Class K_PSAppDataUsagePolicyCache = objc_getClass("PSAppDataUsagePolicyCache");
        PSAppDataUsagePolicyCache *cache = [K_PSAppDataUsagePolicyCache sharedInstance];
        [cache setUsagePoliciesForBundle:@"com.saurik.Cydia" cellular:true wifi:true];

and the entitlements required for iOS 11 & 12:

 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
 <plist version="1.0">
     <dict>
         <key>com.apple.CommCenter.fine-grained</key>
         <array>
             <string>cellular-plan</string>
             <string>data-usage</string>
             <string>data-allowed-write</string>
             <string>preferences-write</string>
         </array>
         <key>platform-application</key>
         <true/>
     </dict>
 </plist>

The code is required to call only once after the initial JB. Could you guys consider adding that piece of code?

11.2.6 iPhone 6 crashes due to Qilin having no support for this device.

Jailbreak never succeeds. App crashes at either 3/50 or 5/50 using MP exploit signed app, from discord. Delectra'd,all tweaks deleted and there were no significant tweaks before. Tried before and after running delectra. App crashing generates no logs. VFS either reboots(exploit fails) or app crashes(when exploit succeeds I suppose). It's not happening only to me, other users are reporting the same problem on discord. with same device. (Might be 4k related?)

cydo returned an error code (255)

Hello everyone! I recently jaibroke my X on 11.3.1 and am unable to upgrade packages or install new tweaks. When trying to do so, I get this error code:

Sub-process /usr/libexec/cydia/cydo returned an error code (255)

Any suggestions?

(In full disclosure: I'm on v2.2.0~b12. Previously, I was on v2.1.3 and getting both error 1 and error 2. Was able to resolve them but now I seem to be stuck. Was hoping when I updated unc0ver that would possibly be it, but not yet.)

How can I get Unc0ver to work on my iPhone 6 IOS 12.5.6?

I am so upset, I saw my iPhone on 12.5.5 and saw that Unc0ver supported 11-14 so I figured I'd update to 12.5.6, because why not? Then I realize that's the ONE VERSION not supported..... IF I HAD JUST DECIDED NOT TO UPDATE, I WOULD BE ABLE TO JAILBREAK I AM SO MAD!!!!

Please tell me IOS 12.5.6 support is coming soon...

Issue with re-jailbreaking iOS 13.5 on an iPhone 11 (unc0ver)
(iPhone 11 Pro running iOS 13.5 - using unc0ver v8.0.2)

Describe the bug A clear and concise description of what the bug is and what you expected to happen.

Yesterday, 1 of my apps stopped working, so I did a hard reboot of my iPhone 11 Pro (running iOS 13.5 with the unc0ver jailbreak). When I went to try to "Jailbreak" it, I keep getting errors & the app keeps crashing. I've been using Unc0ver, & haven't have any issues until yesterday & today.

I have tried using older versions of unc0ver, but still not working.

Here's some images showing the issues I've run into:

Add iOS 13.0-13.3 support for A8-A11 devices

Fix temporary freeze after the jailbreak completed alert

Important Notes:

You must reboot in order to install this update if you are already jailbroken

@Pwn20wnd's substitute bootstrap tooling is used on A8-A11 devices running iOS 13.0-13.3 for battery saving features, improved performance and compatibility reasons

There is no particular reason to switch to the unc0ver jailbreak if you are already running the checkra1n jailbreak (Other than the convenience of being able to re-jailbreak your device without a computer)

Your jailbreak apps and tweaks will be preserved when switching from the checkra1n jailbreak for A8-A11

You can switch back to the checkra1n jailbreak while preserving your jailbreak apps and tweaks but you will need to manually install Cydia Substrate from Cydia after switching back

All devices running iOS 13.0-13.3 are now supported

The connected Apple Watch may re-sync after jailbreak. It will take around a minute or two and it won't touch your data
