As we all know, IOS system is very closed. Usually, we can’t view the content and structure of system files at will like windows and Android system. But GeoFilza developed by GeoSn0w is an app that can view and manage IOS system files, and IOS devices do not need jailbreak.
What is GeoFilza?
GeoFilza was developed by GeoSn0w. It mainly utilizes voucher_swap vulnerability discovered by Brandon Azad and executes filza tools. If you encounter a page card for a long time and the device reboots automatically, that is, the vulnerability attack fails, and you can open it again until you can read the system folder.
The @tihmstar vulnerability allows 4K devices to be used. Due to the low success of exploiting vulnerabilities in the 5S, 6, 6 Plus and iPod Touch 6 devices, it is normal for them to reboot. At present, the author has no solution.At present, “/var” and “/tmp” can be written. The rest of the folders are only read permissions, but there is no write permission.
Supported IOS system: 12.1.3-12.2

How to install GeoFilza?
Because GeoFilza can’t be installed by downloading the enterprise version directly (otherwise it will cause a direct flip back), the author says he can’t find out why, and can only use Cydia Impactor to sign.
Step 1: Install Cydia Impactor on your computer.
Step 2: Download the GeoFilza ipa file.
Step 3: Open Cydia Impactor, connect your computer to your IOS device with a data line, and then drag the newly downloaded GeoFilza IPA file into Cydia Impactor.
Step 4: Then enter your ID account and password (double validation needs to be turned off) as prompted, and wait for the installation to complete.
Step 5: After installing into the mobile phone, an APP named GeoFilza will appear on the desktop. The mobile phone opens the “Settings – > General – > Description File” to find your ID, and clicks Trust.
Step 6: Pay special attention to the fact that the white-card screen is normal for a long time when it is opened, and sometimes it may lead to restart, which is also normal, because exploiting vulnerabilities fails, as long as you click on it again until the iOS folder list appears, it will be successful. In addition, remind us not to close App from the background, which will cause the App to become stuck and unusable when it is turned on. (Keep in mind the system files you don’t know, please don’t delete them indiscriminately. There will be no garbage can retrieve the information and can’t recover. Serious indiscriminate deletion will immediately lead to the disappearance of App desktop and the inability to boot.)
