For legitimate use cases (module replacement, testing), always:
The topic of "Quectel change IMEI" sits at the intersection of technical capability, legal restriction, and ethical responsibility. While the AT+EGMR command and low-level tools like QFirehose offer technical pathways for IMEI modification, these methods carry substantial legal risks in most jurisdictions and technical risks including permanent device damage.
Send AT+QPRTPARA=1 or AT+QPRTPARA=3 first. If it still fails, your firmware version may have permanently locked down NVRAM writing. 2. The IMEI reverts to original after a hard power cut
. However, Quectel does not officially support or document these commands for the public. Quectel Forums Essential Pre-requisites
Standard production firmware on Qualcomm chipsets often locks the AT+EGMR write command. Executing it will return an ERROR or +CME ERROR: 17 (Operation not custom-allowed).
The old RDA chips are trivial to change.
Users should understand that some modifications are not permanent. As documented: "The IMEI check returns the new one but once AT+QCFG='ResetFactory' is called my previously used IMEI is restored" .
Insert SIM card and verify network registration with AT+CREG? and AT+CGREG? .
Type AT and ensure the module responds with OK .
