❓ Frequently Asked Questions

Will rooting void my warranty?›
Rooting trips the Knox counter on Samsung devices. This is irreversible but does not physically damage your device.
Can I unroot later?›
Yes, you can unroot by flashing the original firmware via Odin, or use Magisk’s built-in uninstall option.
Will I lose my data?›
No. The Magisk patched boot method does not wipe your data. Only the boot image is modified.
Is Magisk root safe?›

Will Samsung Pay stop working after root?›

What is the Knox counter?›
