FAQ
Does KernelSU support my device?
KernelSU supports devices running Android with an unlocked bootloader. However, official support is only for GKI Linux Kernels 5.10+ (in practice, this means your device needs to have Android 12 out-of-the-box to be supported).
You can easily check the support for your device through the KernelSU manager, which is available here.
If the app shows Not installed, it means your device is officially supported by KernelSU.
If the app shows Unsupported, it means your device isn't officially supported at present. However, you can build kernel source code and integrate KernelSU to make it work, or use Unofficially supported devices.
Does KernelSU need to unlock bootloader?
Certainly, yes.
Does KernelSU support modules?
Yes, most Magisk modules work on KernelSU. Check Module guide for more info.
Does KernelSU support Xposed?
Yes, you can use LSPosed (or other modern Xposed derivative) with ZygiskNext.
Does KernelSU support Zygisk?
KernelSU has no built-in Zygisk support, but you can use a module like ZygiskNext to support it.
Is KernelSU compatible with Magisk?
KernelSU's module system conflicts with Magisk's magic mount. If any module is enabled in KernelSU, Magisk will stop working entirely.
However, if you only use the su of KernelSU, it will work well with Magisk. KernelSU modifies the kernel, while Magisk modifies the ramdisk, allowing both to work together.
Will KernelSU substitute Magisk?
We believe that it isn't, and that isn't our goal. Magisk is good enough for userspace root solution and will have a long life. KernelSU's goal is to provide a kernel interface to users, not substituting Magisk.
Can KernelSU support non-GKI devices?
It's possible. But you should download the kernel source and intergrate KernelSU into the source tree, and compile the kernel yourself.
Can KernelSU support devices below Android 12?
It's the device's kernel that affects KernelSU's compatibility, and it has nothing to do with the Android version. The only restriction is that devices launched with Android 12 must have a kernel version of 5.10+ (GKI devices). So:
- Devices launched with Android 12 must be supported.
- Devices with an older kernel (some devices with Android 12 also have the older kernel) are compatible (you should build kernel yourself).
Can KernelSU support old kernel?
It's possible. KernelSU is backported to kernel 4.14 now. For older kernels, you need to backport it manually, and PRs are always welcome!
How to integrate KernelSU for an older kernel?
Please check the Intergrate for non-GKI devices guide.
Why my Android version is 13, and the kernel shows "android12-5.10"?
The kernel version has nothing to do with the Android version. If you need to flash kernel, always use the kernel version; the Android version isn't as important.
I'm GKI 1.0, can I use this?
GKI 1.0 is completely different from GKI 2.0, you must compile kernel by yourself.
How can I make /system RW?
We don't recommend that you modify the system partition directly. Please check Module guide to modify it systemlessly. If you insist on doing this, check magisk_overlayfs.
Can KernelSU modify hosts? How can I use AdAway？
Of course. But KernelSU doesn't have built-in hosts support, you can install a module like systemless-hosts to do it.
Why is there a huge 1 TB file?
The 1 TB modules.img file is a disk image file. Don't worry about its size; it's a special type of file known as a sparse file. Its actual size is only the size of the module you use, and it will decrease dynamically after you delete the module. In fact, it doesn't occupy 1 TB of disk space (your device might not even have that much space).
If you really care about the size of this file, you can use the resize2fs -M command to make it the actual size. However, the module may not work correctly in this case, and we won't provide any support for this.
Why does my device show wrong storage size?
Certain devices use non-standard methods to calculate the device's storage size, which may lead to inaccurate storage calculations in system apps and menus, especially when dealing with 1 TB sparse files. Although this problem seems to be specific to Samsung devices, affecting only Samsung apps and services, it's important to note that the discrepancy mainly concerns the total storage size, and the free space calculation remains accurate.
