Since you are doing this without a PC, you need to prepare a few things on your phone itself:
Developers have created APKs that contain the fastboot binary packaged for Android. This allows you to run fastboot commands targeting your own device using a local loopback.
However, due to Android security restrictions (root access is required to send fastboot commands to the bootloader), this method requires root access first. But you need an unlocked bootloader to root. It’s a chicken-and-egg problem.
The Workaround: You must have already unlocked via PC once, or you are on a very old firmware that has a known exploit. For 99% of users, Method 1 is obsolete. Do not waste time looking for a "Fastboot APK" – it won’t work without root.
Verdict: Impractical. Move to Method 2.
This is the only practical, semi-"no PC" method that works for most users. It requires an OTG cable and a second Android phone (or an Android tablet).
| Aspect | Rating | | :--- | :--- | | Difficulty | 8/10 (High risk of bricking) | | Success Rate (2025) | 5% (Only on very old firmware) | | Time Required | 1 hour (including downgrade) | | Risk of Brick | High |
My advice: Find a Windows PC for 15 minutes. The official Asus Unlock Tool is safer, faster, and guaranteed to work on any firmware version. The "no PC" method is a fun experiment for vintage firmware collectors, but not a reliable daily driver solution.
If you are determined to go PC-less and your phone is on Android 8.1 Oreo, follow Method 2 above. For everyone else: respect the bootloader—it was designed to require a physical computer for security reasons.
