Resetting and Uninstalling

Resetting & Uninstalling

OpenKE gives you two ways to go back to stock. They do very different things — pick the right one.

---

Which one do you want?

I want to…	Use
Remove OpenKE's screen and mods, but keep all my Klipper config and print files	Uninstall
Wipe everything — configs, gcodes, OpenKE, all of it — and start from zero	Factory reset
My screen is black / SSH is dead / nothing works	Factory reset via USB (works even with no screen)

---

Uninstall OpenKE

The uninstaller removes OpenKE's screen binary, Klipper mods, and system changes. It keeps your Klipper config (printer.cfg), print files, bed meshes, and calibration data — so you can reinstall later without recalibrating.

Run it

SSH into the printer and run the same installer with the uninstall argument:

sh -c "$(wget --no-check-certificate -qO - https://raw.githubusercontent.com/coreflake1/guppyscreen/main/scripts/installer.sh)" -- uninstall

What it removes

• OpenKE binary and config (/usr/data/guppyscreen/)
• Klipper mods: KAMP configs, Axis Twist module, TMC Autotune config, Skew config
• System patches: probe.py is restored from the backup the installer took
• Init scripts added by OpenKE (the factory reset service, any camera scripts)

What it keeps

• All your Klipper config (/usr/data/printer_data/config/)
• Print files and thumbnails
• WiFi credentials
• Creality cloud account

If anything wasn't auto-restored, the installer left a backup at /usr/data/guppyify-backup/ — restore files from there manually and reboot.

After uninstalling

The stock Creality screen binary comes back on the next reboot. The Klipper interface (Mainsail/Fluidd) still works as normal.

To reinstall OpenKE later, just run the installer again.

Factory Reset

A factory reset wipes the printer to exactly how it came from the factory — no configs, no gcodes, no mods. Use this only when you need a truly clean slate or the printer is in an unrecoverable state.

⚠️ This is destructive and not reversible. Your Klipper config, print files, calibration data, and all OpenKE mods are gone. WiFi credentials and the Creality cloud account are preserved.

Method 1 — USB drive (no SSH required)

Works even when the screen is black, Klipper is dead, or SSH isn't responding.

1. Format a USB drive as FAT32.
2. Create an empty file named exactly emergency_factory_reset in the root of the drive (no extension, no .txt).
3. Eject the drive, then plug it into the printer while it is powered off.
4. Power the printer on. The service detects the file, renames it to .old (so it won't repeat), wipes everything, and reboots into stock firmware.

Method 2 — Screen (Settings panel)

Open Settings → System Info → Reset Options → Factory Reset Printer → red Confirm button.

Method 3 — SSH

/etc/init.d/S58factoryreset reset

What gets wiped

Path	Outcome
/overlay/upper/	Wiped — all system-level modifications removed
/usr/data/guppyscreen/	Wiped — OpenKE binary and config
/usr/data/printer_data/	Wiped — Klipper config, gcodes, calibration
/usr/data/printer_data/logs/	Kept — logs survive for diagnosis
/usr/data/wpa_supplicant.conf	Kept — WiFi credentials survive
/usr/data/creality/	Kept — Creality cloud account & device identity

After the reset

The printer boots into stock Creality firmware. To get OpenKE back:

sh -c "$(wget --no-check-certificate -qO - https://raw.githubusercontent.com/coreflake1/guppyscreen/main/scripts/installer.sh)"
