The MC801A employs secure boot chains. This means that simply flashing a modified NV (Non-Volatile) memory file—which contains the IMEI—is blocked by the device's security architecture. You cannot simply connect via USB and write a new number as you might have done on older smartphones.
Once Diag Mode is active, technicians utilize specialized NVRAM editing tools (such as QXDM, QPST, or third-party service software): are installed so the device is recognized as
If you are having trouble connecting devices, you can use the WPS button on the router to pair them automatically. Device Management: You can manage blocked devices through the Block List in the Wi-Fi settings menu of the web interface. Are you experiencing a specific connectivity issue
