Or physically restart your laptop / re-seat the modem.

In some firmware versions, the modem accepts standardized or semi-proprietary AT commands through a terminal interface (like PuTTY or Minicom). : AT+EGMR=1,7,"YOUR_NEW_IMEI" .

Here is a high-level, unverified technical workflow discussed in reverse-engineering circles:

: Flashing custom or incorrect firmware on the L850-GL can sometimes "wipe" or reset the IMEI. Many community forums report that there is currently no known reliable way to restore or change the IMEI on this specific model if it becomes invalid after such a flash.

: Some modules require you to enable the editing of parameters. This might involve using a specific AT command like AT+EGMR=1,1 to enable writing.

often return errors on the L850-GL. Some users suggest these commands only work for restoring a factory IMEI, not for spoofing a new one. Firmware Risk
