Requirements

• Nothing Phone 1 with unlocked bootloader
• A Windows PC or Linux/Mac terminal
• Latest Platform Tools
• 7-Zip installed
• Compatible fastboot-flashable stock ROM (you can usually find on XDA or community forums)
• USB cable (preferably the original one)

Steps to Go Back to Stock ROM:

I. 🔽 Download Required Files

• image-boot.7z
• image-firmware.7z
• image-logical.7z.001 to .00x (depending on build)
• Flashing Script: flash_stock_rom.bat (Windows) or flash_stock_rom.sh (Linux/Mac)

Place all these files in a single folder for convenience.

---

II. 📦 Extract Image Files

On Windows:

• Right-click → Extract Here (with 7-Zip)

On Linux/macOS:

7za -y x image-logical.7z.001

Make sure all .img files are extracted into the same folder as your flashing script.

---

III. 🧰 Prepare Drivers (Windows)

• Install the Google USB Driver (or Nothing Phone driver if available).
• Go to Device Manager → confirm Android Bootloader Interface appears when phone is in Fastboot mode.

---

IV. 🔁 Boot to Fastboot Mode

1. Power off your device
2. Hold Volume Down + Power
3. Connect your phone to the PC using USB

---

V. ⚙️ Flash the Stock ROM

1. Run the flash script:
   • flash_stock_rom.bat (Windows)
   • bash flash_stock_rom.sh (Linux/Mac)
2. Follow on-screen prompts:
   • ✅ Confirm actions
   • 📱 Choose to wipe data (Y/N)
   • 📶 Choose to flash both A/B slots (recommended: Y)
   • 🚫 Disable AVB (Android Verified Boot)? (Usually: N)
3. The script will:
   • Flash all image files
   • Ensure proper partitioning
   • Show success or error status

---

VI. Reboot to System

If everything flashed correctly:

fastboot reboot

If errors occurred:

Why Use This Method?

• Ensures cleanest return to stock
• Full re-flash of every system partition
• Helps unbrick a soft-bricked Nothing Phone 1
• Useful when ADB sideload or OTA methods fail

Common Flashing Errors & Fixes

1. “fastboot: error: cannot load ‘boot.img’”

This usually happens when the file is missing or misplaced. Make sure all image files, like boot.img, are extracted properly and located in the same folder as your flashing script or terminal.

2. “FAILED (remote: flashing is not allowed in lock state)”

Your bootloader is likely still locked. To fix this, unlock it by entering:

fastboot flashing unlock

Once unlocked, repeat the flashing process.

3. Device stuck in bootloop after flashing

If your Nothing Phone 1 keeps restarting, try flashing the ROM to both A and B slots when prompted. If it still doesn’t work, do a factory reset from recovery and flash again.

4. “Invalid sparse file format” or flashing stops part-way

This is typically caused by an outdated or corrupted fastboot tool. Download and use the latest platform-tools from Google to ensure compatibility.

5. Device not showing up in Fastboot mode

First, check if your PC detects the phone. If not, install the correct USB drivers. On Windows, go to Device Manager and look for “Android Bootloader Interface.” If it’s missing or marked with a warning, reinstall the drivers manually.

6. The flash script crashes or exits halfway

This usually indicates that the ROM was either not extracted properly or the script is outdated. Re-extract the files using 7-Zip, and ensure you’re using a reliable flash script from a trusted source like the official Nothing community or XDA.

7. Data still exists after flashing stock ROM

If you want a completely clean install, make sure to select “Yes” when asked whether to wipe data during the flash process. If you skipped it, boot into recovery after flashing and perform a factory reset.
