What happens when a jailbreak tweak bugs out on your device and ends up in a boot loop? Do you try to reboot the device to no avail? Do you take to the internet to ask how to fix it?
How about this: try booting into a form of booting up that Saurik calls ‘No Substrate Mode,’ then uninstall the faulty tweak.
In this piece, we’ll talk about how you can use No Substrate Mode, an under-used feature of jailbroken iPhone or iPad that can truly save you from losing your precious jailbreak when you’re unable to turn on your device.
We’ve talked quite a lot about Recovery OS, an underestimated feature of OS X that makes it easier to troubleshoot your Mac even if it refuses to start up properly.
But as you’ll see for yourself in this post, Recovery OS is but one of the more than dozen different ways to start up your computer, aside from OS X’s regular startup mode. In this tutorial, we’ll list all the ways you can start up your Mac and detail each one.
But there will be times when a rogue app, a misbehaving service, outdated caches and other issue will cause your Mac to slow, stop starting up or exhibit other unwanted symptoms. Thankfully, Apple has provided a way to boot OS X in Safe Mode.
In Safe Mode, your Mac prevents some software, such as startup items, from loading. What does get loaded are the bare minimum level of drivers and essential software. This is by design, to help you troubleshoot your Mac and isolate the cause of a software conflict. As a bonus, booting in Safe Mode also forces a check of your startup disk.
Here’s what you need to know about Safe Mode on OS X, when you should use it and how to startup up any Mac in Safe Mode and get back to normal.
Substrate Safe Mode, the package that allows jailbreakers to safely boot into Safe Mode and remove uncooperative packages, has been updated to version 0.9.5000. The update, which was pushed by Saurik just recently, fixes a fairly significant issue related to CPU usage.
Safe Mode works similar to the Safe Mode on desktop machines, as it allows you to boot without loading certain extensions, allowing you to troubleshoot problem extensions. Have a look inside for more details.
Good news this morning for jailbreakers. Following the release of the new Mobile Substrate for iOS 7, Saurik has updated Substrate Safe Mode to be more friendly with the newer firmware and newer A7 devices like the iPhone 5s and iPad Air.
For those unfamiliar with it, Safe Mode is what prevents your device from entering a permanent crash cycle by giving you a chance to uninstall problematic packages. And until now, it wasn’t behaving nicely with the Mobile Substrate update…
If you need to quickly boot your iDevice into safe mode, there are quite a few options available on Cydia in order to do so. One of the latest tweaks available via Cydia is InstaSafe, which places a dedicated safe mode button conveniently on the SpringBoard.
Take a look inside as we show you how InstaSafe works in this video demonstration…
Did you know that the iPhone had a “Safe Mode?” Safe Mode on the iPhone has been apart of jailbreaking for years now, but many people still don’t understand it. If your iPhone is jailbroken, Safe Mode will be invoked when MobileSubstrate (the Cydia support framework) crashes.
Desktop operating systems, like Windows and Mac OS X, have had a “Safe Mode” for a long time. On the desktop, safe mode is used for removing corrupted processes that may be causing the operating system to not function properly.
The iPhone has a “Safe Mode” for that exact same reason. A simple Cydia app called “Safe Mode Launcher” allows you to invoke the iPhone’s Safe Mode with one tap. Let’s take a look…
Yesterday night, I was quietly watching some bad reality TV when a push notification showed up on my iPhone. I grabbed the phone, looked at the notification and I slid to unlock the phone in order to launch the mail.app.
To my surprise, the following screen appeared.
What’s strange is that I wasn’t doing anything with the phone. That day, I did nothing but installing a new app (TomTom), and I am 100% positive I didn’t mess with any of the settings.
I had heard about the iPhone safe mode before but I had never experienced it until today. I know the iPhone can only get into safe mode on jailbroken iPhones and that it has something to do with the fast respring. That’s about all I know about this issue.
I simply tapped “OK” and turned off the phone. For a minute, I was scared that the problem would persist after rebooting the iPhone but it didn’t.
Has your iPhone been into safe mode before? If so, why do you think that happened?
