Because Microsoft will be discontinuing support for Silverlight, the Silverlight version of Navigator Web is being phased out. All CTI Navigator users should use Web II (HTML version) unless there is a specific need to temporarily use Navigator Web Silverlight (such as to import and convert Matchmakers from Desktop Navigator into Navigator Web format). However, until Microsoft stops Silverlight services, Navigator Web Silverlight will continue to run.
Click on the topic in the list below to go directly to the appropriate instructions:
Silverlight is a browser plug-in (also called an add-on or add-in). If Silverlight does not install (or repeatedly prompts to install), or does not run properly in your browser (displaying either a System Exception error, an error 4001, a blank page, or a blank frame without the menu items in Navigator Web), progressively implement each of the following steps until the problem is resolved:
For continuing Internet security updates in Windows XP and Vista, run Silverlight in the Opera browser (rather than Internet Explorer or Chrome which no longer issue security updates for versions of Windows no longer supported by Microsoft).
Close the browser with the problem, and open Navigator Web in a different browser.
If Silverlight is installed, enabled, and the browser's temporary Internet browsing files have been completely cleared, but Silverlight does not work properly in any browser on this computer, Un-install Silverlight and then install the latest version. If uninstalling and reinstalling Silverlight does not resolve the problem, see the "Clean Corrupted Silverlight Installation in Windows " or "Fix Silverlight in Mac" section below as appropriate.
If Silverlight runs correctly in one browser but not correctly in another browser on your computer, the non-supporting browser itself may need to be reset, restored, un-installed and re-installed, or replaced by an earlier version. For instructions on managing browsers, see "Fix Internet Browser Issues" in the Related Articles at the end of this web page.
To verify the version of Silverlight installed on a computer, click here (or go to http://www.microsoft.com/getsilverlight/Get-Started/Install/Default.aspx). At this website Microsoft also provides install and uninstall instructions, and a chart of compatible operating systems and browsers for the version of Silverlight installed on your computer. If your installed version is earlier than the "current" (latest) version, you can click on the "Current version" number to install it on your computer if desired.
To verify the version of Silverlight installed on a Mac, you can click Help and select "Installed Plug-ins" in the Safari browser menu. Then scroll down to view the Silverlight Plug-in information.

The basic installation steps are:
Note: Some security programs (such as STOPzilla, VIPRE and Webroot) need to be temporarily disabled to allow Silverlight to install properly.

Normally add-ons/plug-ins such as Silverlight are automatically enabled when installed. However, they can be disabled manually, by other programs, or by browser updates.
Internet Explorer (IE). To ensure that Silverlight is installed and enabled to run in Internet Explorer (8 and later):
If using software rendering does not fix IE's "stopped working" error, re-set Internet Explorer to its defaults (as described here). If the "stopped working" error persists, set IE to use Compatibility View for the website (as described here).
Firefox. To ensure that Silverlight is installed and enabled to run in Firefox:
To activate a plugin (such as Silverlight or IE Tab) on a web page in Firefox on a Mac, you can either:
If you cannot type in a text or data entry box for CTI Navigator Web in Firefox on a Mac, activate the Silverlight plug-in for the current web page as described above. Otherwise, use the Safari browser in unrestricted mode on a Mac.

Chrome on Windows. Starting with version 45, Chrome will no longer support legacy plug-ins such as Silverlight in Windows. Therefore to enable Silverlight to run in Chrome on Windows, always add the IE Tab extension to your Chrome (as described here).
Prior to version 45, Chrome can be set to enable Silverlight to run in Windows as follows:
Chrome on Mac. Starting with version 42, Chrome no longer supports plug-ins such as Silverlight on a Mac.
Opera. To ensure that Silverlight is installed and enabled to run in the Opera browser:
Note: For continuing Internet security updates in Windows XP and Vista, run Silverlight in the Opera browser (rather than Internet Explorer or Chrome which no longer issue security updates for versions of Windows no longer supported by Microsoft).
Safari. To ensure that Silverlight is installed and enabled to run in Safari (6.0 and earlier):
▲ Back to the index at the Top of this web page
To provide an extra level of security, Safari automatically sandboxes (see sandbox note below) all plug-ins (such as Adobe Flash and Microsoft Silverlight) to limit their access to key system resources. However, Safari (6.1 and later) includes a plug-in manager that allows users to set the level of security to be enforced for specific plug-ins, either on a per website basis (such as just for the website where CTI Navigator Web runs for your MLS) or globally (for all other websites).

Reviewing the Realme C30s IMEI repair process requires distinguishing between hardware-level "repairing" (restoring a lost original number) and illegal "changing." For those dealing with "Invalid IMEI" or "IMEI Null" issues after a software update or firmware crash, professional tools like the Pandora Tool ChimeraTool are the industry standards for technicians.

is typically required if the device displays a "NULL" IMEI or a "0000..." placeholder after a firmware update or software crash. Since this model uses a Unisoc (Spreadtrum) SC9863A1 chipset, the process differs from standard MediaTek or Qualcomm devices. Common Repair Tools
Professional service tools are generally required to rewrite the IMEI to the device's NVRAM:
Pandora Tool: A popular professional box that has been verified to support Realme C30s IMEI repair on Android 12. Realme C30s IMEI Repair: The Ultimate Guide to
UnlockTool: Frequently used for flashing and bypassing FRP on this model; it can often handle baseband-related issues via the Spreadtrum module.
SPD (Unisoc) Service Tool: Official or third-party service tools designed for Spreadtrum CPUs can sometimes "Write" the IMEI in Diag Mode or Meta Mode. General Repair Workflow
Backup Data: Ensure all personal data is backed up, as these tools often require a factory reset or flashing.
Enable Diag Mode: Most repair software requires the phone to be in "Diagnostic Mode" or "Flash Mode" (often triggered by holding Volume Down while connecting to a PC).
Write Original IMEI: Enter the original IMEI found on the device box or back sticker.
Note: Changing an IMEI to a different number is illegal in many jurisdictions. These tools should only be used to restore the device's original identity.
Flash Stock Firmware: If the software repair fails, you may need to re-flash the official stock ROM to repair a corrupted baseband partition. Hardware Considerations
If the IMEI remains "NULL" after multiple software attempts, the issue might be hardware-based. Technicians often check for:
EMMC Corruption: Failure of the storage chip where IMEI data is stored.
Baseband CPU Issues: Damaged solder joints on the CPU or Modem IC may require "reballing" the chip.
Are you seeing a "NULL" IMEI or is the phone failing to catch a signal despite having an IMEI? Step 2: Write IMEI via Maui Meta
The Realme C30s is a budget-friendly smartphone, and like many devices, it has a unique IMEI (International Mobile Equipment Identity) number that identifies it on mobile networks.
If you're experiencing issues with your Realme C30s's IMEI, such as it being invalid, null, or not recognized, there are a few methods to repair it. However, please note that these methods may void your warranty, and you should proceed with caution.
Some common reasons for IMEI issues on the Realme C30s include:
Here are some possible methods for repairing the IMEI on your Realme C30s:
Before attempting any repair method, make sure to:
Keep in mind that if your device is not registered or is reported as lost or stolen, repairing the IMEI may not be possible.
If you're not comfortable with DIY repairs or are unsure about the process, it's recommended to visit an authorized Realme service center or a professional repair shop for assistance.
Would you like more information on a specific method or guidance on how to proceed?
Ensure battery level is above 60%.
A: Check your baseband version in Settings > About Phone. If it shows “Unknown,” you have a modem firmware mismatch. Flash the correct lk.bin and preloader.bin from the original stock ROM.
System Exception Error: if Silverlight cannot access needed computing resources (such as extra working memory), CTI Navigator Web functions may fail and display a "System Exception error" message. System Exception errors may or may not be fatal. Other Navigator Web functions may continue to operate correctly, and the failed function may recover if needed resources become unblocked or become available (such as by closing other browser screens or apps to free up working memory). However, to avoid System Exception error interruptions, always set Safari's Preferences to run Silverlight in Un-safe mode (as described above).
Sandbox Note. Sandboxing is a security mechanism to tightly restrict access to computer memory, operating system resources, and user files for unknown or untrusted code or unknown or untrusted websites.
Note that third-party plug-in managers (such as ClickToPlugin) may interfere with or override settings in Safari’s plug-in manager.
