If you are in ownership of an iPhone or iPad running iOS 10.3.x and are jailbroken using the excellent and stable G0blin, Meridian, or h3lix jailbreak tools, then you may have experienced some issues using Cydia Eraser. You’ll be glad to learn that with just a little bit of file modification it’s actually possible to get the Eraser app working without issue.
As most jailbreakers will know by now, Cydia Eraser is a highly useful tool which allows a device owner to essentially remove all aspects of the jailbreak and “restore” back to a stock version of the firmware that they are currently running.
This is in direct contrast to an iTunes restore, which could force you to upgrade that firmware to the latest version, therefore removing the ability to jailbreak at a later date. However, a tool can only do its job efficiently if it is compatible and working with the firmware that it’s actually running on.
Let’s dive in and take a look at the requirements and process needed to get Cydia Eraser working on iOS 10.3.x devices.
Part of the process involves deleting and amending files, so the Filza File Manager is also a required installation.
Step 1: Using the Filza File Manager app, navigate to the following directory: /Applications/Eraser.app/.
Step 2: Inside of that directory you should find a file named Eraser_. Delete the file entirely.
Step 3: You should also find a file simply called Eraser. Modify that file and rename it to Eraser_.
Step 4: Now, exit out of the Filza app. Reboot the device. When the device starts up again you will need to go through the jailbreak process once again using the jailbreak tool for iOS 10.3.x of your choice.
Step 5: And there you have it. Once rebooted and re-jailbroken, the Cydia Eraser application should be functional.
The process above should ensure that you have the ability to use Cydia Eraser for its intended purposes on your jailbroken iOS 10.3.x device even though it still hasn’t been update officially by Saurik for 10.3.x. It’s still possible that you may encounter some niggles or issues, but, all things well, following the above process should give you a positive and trouble-free experienced.
That said, if you happen to get an error titled “cpp:131 error”, using Filza File Manager, navigate to /etc/. Here you will find the hosts file, and will be renaming it to “hosts.old”.
Or perhaps you encounter the “zip:444 error”. This one is relatively simpler to solve; simply remove the app from the App Switcher and try once again.
