Featurephone IMEI editor codes

------------------------------

These secret codes have been tested on most non-Nokia featurephones manufactured since 2016. They open either the IMEI editor directly, or the engineering menu where it can be found (like "Para Set" - "Update IMEI Number" on Mocor-based phones). In some cases, you may be required to press the Call button after entering the code, so please test both options.

This list will be updated from time to time but it already covers over 80% of

cheap featurephones on the market.

Bonus:

For MediaTek-based featurephones (MT6260, MT6261, MT6276 chipsets) without secure boot, if you find a way to open a USB-COM connection, you can also use the following AT commands to update IMEIs (the change will take effect after rebooting the phone):

For SIM1: AT+EGMR=1,7,"newimei"

For SIM2, if present: AT+EGMR=1,10,"newimei"

For SIM3, if present: AT+EGMR=1,11,"newimei"

For SIM4, if present: AT+EGMR=1,12,"newimei"
