A lot of users are reporting that Yalu jailbreak is getting stuck on a white or black screen. Fixing this is really is simple so let’s get right into it.

Why yalu/mach_portal gets Stuck on Black or White Screen?

Before we fix this error, let’s analyze why this error occurs in the first place.

The 2 main reasons why this happens are –

• Using the wrong version of Yalu jailbreak on your device.
• Conflicting Cydia tweaks installed on your device.

90% of the time, the jailbreak gets stuck black or white screen due to a bogus or conflicting Cydia tweak.

Apart from this, this error can also occur due to a problem with your display. If that’s the case then you should get your screen replaced altogether.

How to Fix yalu/mach_portal Stuck on Black or White Screen

Method 1. Use mach_portal+yalub3 OR yalu102b7

A lot of users who face this error are using the latest version of mach_portal, which is, beta 4. The latest version is the most stable, in theory.

However, in this case it’s clearly broken and will throw errors on your device. The best way to steer clear of all errors is to use mach_portal+yalu beta3 and yalu102 beta7 IPA.

If you are still using an older version of Yalu jailbreak, follow this guide to upgrade or downgrade to the recommended beta versions.

Method 2. Uninstall Conflicting Cydia Tweak

This is the major reason why you are getting the dreaded black screen.

You can fix this issue by performing the following steps –

• Enter No Substrate mode on your device. If you don’t know how to do this, follow this step by step guide.
• Remove the conflicting tweak. It is usually the last tweak you installed.

That’s all there’s to it. Hopefully, the black or white screen should be solved by now.
