Kingroot 4.1
The "unroot" feature in version 4.1 frequently left behind system files, traces of the su binary, or caused boot loops. Once you install KingRoot, it is often easier to factory reset the device than to cleanly unroot.
The technical sophistication of KingRoot 4.1 was impressive. The developers maintained a massive database of device-specific exploits. When a user hit the "Root" button, the app didn't just run one script; it fingerprinted the device. It identified the exact Android version, the kernel build, and the chipset architecture, then deployed the specific exploit known to work on that configuration.
However, this efficiency came at a cost.
Even a stable version fails sometimes. Here are frequent issues and fixes: kingroot 4.1
When using KingRoot 4.1, you may encounter these issues:
If you're reviving a 2014–2015 phone, you have three options:
| Tool | Difficulty | Success Rate (Android 4.4–5.1) | Safety | | :--- | :--- | :--- | :--- | | Kingroot 4.1 | Easy (1-click) | 80% | Moderate (replace after) | | Magisk (v18.1) | Hard (requires custom recovery) | 95% (if bootloader unlockable) | High | | Framaroot | Easy | 30% (outdated exploits) | Low | | CF-Auto-Root | Medium (needs PC + Odin) | 99% (Samsung only) | High | The "unroot" feature in version 4
Recommendation: If your bootloader can be unlocked, use Magisk. If not, Kingroot 4.1 is your best bet.
If you are using a device old enough for KingRoot 4.1, you might wonder why not use something newer. Here is the comparison:
| Feature | KingRoot 4.1 | Magisk (v20+) | SuperSU (CF-Auto) |
| :--- | :--- | :--- | :--- |
| Systemless Root | No (modifies /system) | Yes | No |
| Open Source | No | Yes | No (after Chainfire sold it) |
| Works on Android 8+ | No | Yes | No |
| Hide Root from Apps | No | Yes (MagiskHide) | No |
| Ease of Use | 1-click | Moderate (requires custom recovery) | Moderate |
| Safety | Low (unknown code) | High (audited) | Medium | The technical sophistication of KingRoot 4
Verdict: Only use KingRoot 4.1 if your device is too old to support a custom recovery (TWRP) or Magisk.
⚠️ Note: Kingroot 4.1 will not work on Android 7.0 (Nougat) or newer.
