Complete Guide: Installing OmniSD & Restoring IMEI on Nokia 8110 4G

Nokia 8110 4G

Important Preliminary Warnings

Legal Notice: Restoring your original IMEI (from your device's box) is generally legal for repair purposes. However, changing an IMEI to a number not originally assigned to your device is illegal in most countries.

Data Loss Warning: This process will wipe all data on your device. Back up any important information beforehand if possible.

Warranty Void: This process will void any remaining warranty on your device.

Risk of Bricking: Incorrect procedures may permanently damage your device. Follow each step carefully.

📋 Phase 1: Preparation and Prerequisites

Required Materials:

1. Nokia 8110 4G with its original IMEI numbers (from the box).
2. A Windows, macOS, or Linux computer.
3. A reliable Micro-USB data cable.
4. A MicroSD card (formatted to FAT32). A 16GB card is more than sufficient for this process, as the files you need are very small (often less than 1MB).
5. Your phone's battery should be charged to at least 50%.

Software to Download:

1. Firefox ESR 52.9 (for WebIDE):
2. Android SDK Platform-Tools (for ADB and Fastboot):
3. OmniSD Package (the jailbreak enabler):
4. Wallace Toolbox (the main utility):

🔧 Phase 2: Setting Up the Environment

Step 1: Install and Configure Firefox ESR 52.9

1.  Install Firefox ESR 52.9 on your computer.

2.  Open it and disable automatic updates:

    -   Go to Menu > Options > Advanced > Update and select Never check for updates.

3.  Enable WebIDE:

    -   Go to Tools > Web Developer > WebIDE or press Shift + F8.

Step 2: Set Up ADB on Your Computer

1.  Extract the downloaded Android SDK Platform-Tools to a folder on your computer (e.g., C:\platform-tools).

2.  Add ADB to your system's PATH environment variable for easy terminal access.

3.  Test the installation by opening a command prompt or terminal and typing:

adb version

    You should see the version number displayed.

Step 3: Prepare the MicroSD Card

1.  Format the MicroSD card to FAT32 (This is very important).

2.  Create a folder named apps in the root directory of the SD card.

3.  Copy the wallace-toolbox.zip file into this apps folder.

4.  Insert the SD card into your powered-off Nokia 8110 4G.

📱 Phase 3: Enabling Debug Mode on Your Nokia 8110 4G

1.  Insert your battery, then power on the phone.

2.  Update your phone's firmware to the latest version (if not already):

    -   Go to Settings > Device > Device Information > Software Update.

3.  Enable Debug Mode:

    -   On the home screen, open the dialer and enter the secret code: *#*#33284#*#* (which spells *#*#DEBUG#*#*).

    -   A bug icon (#) should appear in the status bar, indicating debug mode is active.

💻 Phase 4: Connecting the Phone to WebIDE

1.  Connect your phone to the computer using the Micro-USB cable.

2.  On your computer, open a terminal or command prompt and run:

adb devices

    This should list your device. If it doesn't, ensure USB debugging is enabled.

3.  Forward the required port for WebIDE:

adb forward tcp:6000 localfilesystem:/data/local/debugger-socket

4.  In Firefox ESR, open WebIDE (`Tools > Web Developer > WebIDE`).

5.  In WebIDE, select Remote Runtime and set the address to `localhost:6000`.

6.  Click Connect. If successful, your device's name should appear in WebIDE.

🛠️ Phase 5: Installing OmniSD (The Jailbreak)

This step gives your phone the ability to sideload apps.

1.  In WebIDE, click Open Packaged App and navigate to the extracted `omnisd` folder. Select it.

2.  Click the green Play button (▶) in WebIDE to install OmniSD onto your phone.

3.  On your phone, open the OmniSD app (it should now be in your app menu).

4.  Press the # key on your phone's keypad and confirm the prompt to perform a privileged factory reset. This will wipe your data and reboot the phone.

📦 Phase 6: Installing and Using Wallace Toolbox

Step 1: Install Wallace Toolbox

1.  After the reset and reboot, re-enable debug mode by dialing *#*#33284#*#* again.

2.  Reconnect the phone to WebIDE (repeat the steps in Phase 4 to forward the port and connect).

3.  In WebIDE, select Open Packaged App and navigate to the wallace-toolbox-master folder you downloaded earlier. Select it.

4.  Click the Play button (▶) in WebIDE to install Wallace Toolbox onto your phone.

Step 2: Using Wallace Toolbox to Restore IMEI

1.  On your phone, open the Wallace Toolbox app from the app menu.

2.  You will see a list of options, each mapped to a key on your keypad. The options are color-coded:

    -   WHITE: Generally safe functions.

    -   RED: Pot dangerous functions that can erase data or affect system stability. IMEI editing is a RED function.

3.  First, you need to enable privileged access. Press the # key on your keypad to "Enable developer menu and privileged access". Your phone may reboot.

4.  After reboot, reopen Wallace Toolbox.

5.  To restore your first IMEI, press the `5` key ("Edit IMEI1").

6.  Carefully type your original, 15-digit IMEI number (from your phone's box) using the keypad and confirm.

7.  If your phone is dual-SIM, press the `6` key ("Edit IMEI2") and enter the second IMEI number with the same care.

8.  Once completed, exit the app and fully power off your phone (remove the battery and reinsert it after a few seconds).

Note: Wallace Toolbox uses a temporary root method. The IMEI change is written directly to the modem partition, making it persistent across reboots.

✅ Phase 7: Verification and Final Steps

1.  Power on your phone.

2.  Open the dialer and enter the code: *#06#.

3.  The displayed IMEI(s) should now match the numbers from your phone's box.

4.  Disable Debug Mode (dial *#*#33284#*#* again to toggle it off) for security.

5.  Optional but Recommended: Perform a standard factory reset (Settings > Device > Reset phone) to ensure system stability after the modifications.

🆘 Troubleshooting Common Issues

Issue and their Possible Solution 

WebIDE won't connect: Ensure you used adb forward correctly. Try rebooting both phone and computer. Try a different USB cable or port. 

Unauthorized in ADB: Check that debug mode is active (bug icon visible). On your phone's screen, approve the computer's RSA key fingerprint prompt if it appears.

Wallace IMEI edit fails: Ensure you enabled privileged access first (pressed #). Ensure you are using the correct, original IMEI.

Phone stuck on boot: Force reboot by removing the battery. If persists, you may need to reflash stock firmware using a computer and Qualcomm Flash Tool.

🔄 Beyond IMEI Repair: Other possibilities

Once jailbroken with OmniSD and Wallace Toolbox, your Nokia 8110 4G can:

Sideload any app: Install third-party apps and ports of old Firefox OS apps.

Remove pre-installed apps: Use Wallace's Make all apps removable function (Right soft key) and then uninstall them normally.

Install Custom ROMs: Flash community-developed ROMs like GerdaOS for even more control and features (search BananaHackers for guides).
