How to Fix Magisk Process Error Installation Failed
Process error usually indicates an issue during the flashing process. This could be due to a corrupt or incompatible file that was downloaded or a lack of storage access given to the file manager app. Although the error log can pinpoint the exact reason, the following methods can help troubleshoot the problem without it.
Redownload Zip File
The Magisk Process Error Installation Failed error usually occurs due to incompatible or corrupted files. If you download a file with a slow internet connection, there is a slight chance that the download may become corrupted. Therefore, it is recommended that you check the downloaded file with its checksum or download it from an official source to avoid encountering this error.
Check Zip Format
Magisk can only work with ZIP or IMG format files that are compressed. Attempting to install any other file format will result in installation errors. Occasionally, the flashing zip downloaded from the internet could be in 7z or RAR format. In order to obtain the Magisk-compatible ZIP or IMG formats, you must extract these files.
Check App Storage Permissions
In many cases, it is quite possible that the ZIP file is correct and valid, but the file manager app you use within Magisk does not have storage permissions. So eventually, Magisk will start the installation process, but will not be able to find the file and hence the installation error!
So to fix this, you have to make sure the app has relevant storage permission. Assuming you will be using EX File explorer as a file manager app, here are the steps to give storage permissions.
Open ES File Manager or download it fresh from the Playstore.
It will ask you for storage permission, Grant all permissions. After this, start the Magisk installation process and select ES file explorer when it asks for flashable zip file access, it will not show any errors now.
Check File Permissions
Make sure the file you are flashing have both Read, write and executable permission. It is important to have these permissions as without these, you cannot access the file and hence Magisk will not be able to flash it on your phone.
You can easily check or change file permissions with ES file explorer.
Find FIle location and choose to change permission from file options.
Here make sure all the checkboxes are ticked under-read, write and executables.
Read Error Log
The above methods will surely help to clear all possible errors, but there are many reasons on why you are facing the installation error. To get a clear picture, it is important to check the error log from Magisk.
java.io.FileNotFoundException: /storage/emulated/0/boot.img: open failed: EACCES (Permission denied).
As you see in the above error log, we can easily identify that issue is due to permissions denied – so we can go ahead and grant relevant permission to the app. Similarly, there can be different issues that you will be able to identify from the error log only.
