Please give me a method to change the IMEI for E5577CS-321 .
Specifications:
Found modem: E5577Cs-321
Model: Huawei AuthVer 4 modem (New)
IMEI: 860783033178xxx
Serial NR: D2LDW16721003xxx
Firmware: 21.322.01.01.401
Compile date/time: Mar 9 2017 14:23:43
Hardware version: CL1E5573SM11
Dashboard version: WEBUI_17.100.20.01.401_MRE5
Web UI version: WEBUI_17.100.20.01.401_MRE5
SIM Lock status: unlocked
Wrong codes entered: 0 (unlock attempts left: 10)
When using the command:
Code:
AT^CIMEI="xxxx"
The IMEI changes to the new value, but the router displays "No Service" and there is no signal.
Once I restore the original IMEI, the connection returns.
What is the solution to change the IMEI without losing the signal?
