- Hold the RST (Reset) button with a paperclip.
- While holding RST, press the Power button. Release RST after 5 seconds.
- The screen will flicker and display "Update system from USB..." in yellow text.
Step 3: The Flash Process
- The system will verify the
userdebugsignature. You will see a red warning:"Warning: This is a userdebug build. Security is disabled."Press "Continue." - A progress bar will appear. Phase 1 (System partition): 2 minutes. Phase 2 (Boot image): 30 seconds. Phase 3 (OEM config): 10 seconds.
- Do not touch the screen or turn off the ignition. If the bar freezes for more than 5 minutes, you have a stale USB drive. Reformat and try a different port.
Step 4: First Boot (The Long Wait)
- After completion, the unit will reboot to the "Android is starting... Optimizing app 1 of 45."
- On userdebug builds, this takes 4–5 minutes (versus 90 seconds for user builds) because the system is recompiling apps with debug symbols.
2. Debug-Specific Update Features
- Preserving root after updates
- Keeping
userdebugflags - Maintaining ADB root access
8. Conclusion & Action Items
The KSW-Q-userdebug update succeeds in delivering required kernel and driver fixes for internal validation. However, its debug-oriented nature (permissive SELinux, test keys, root access, high logging) makes it strictly forbidden for customer/end-user devices.
