While this is a Sierra forum, I understand you can change the Quectel EP06 modem IMEI via sending AT commands such as
Code: Select all
AT +EGMR=1,7 "New IMEI#"
Thank you!

Interesting. I dug and dug and came up empty.Yipzy wrote: Sun Dec 29, 2019 9:18 pm It's possible now thanks to bkerler https://github.com/bkerler/SierraWirelessGen to unlock Engineer Mode and issue the enhanced commands meant for testing purposes. Do some more digging and I believe you will find the answer. Sierra has pretty good modems unless you are on Sprint then I advise you to not use the MC7455 variant due to a lot of disconnects for most people who have it.

I wonder if it also works for Quectel EM12 because then it would be the main reason to choose Quectel over Sierra modem for a new router.pengo wrote: Tue Dec 10, 2019 9:48 am While this is a Sierra forum, I understand you can change the Quectel EP06 modem IMEI via sending AT commands such asCode: Select all

Make sure you can access the serial port of the modem so that you can send AT commands to the modem. It varies from different operating systems.Garbage internet wrote: Fri May 15, 2020 3:29 pm So I need to repair a Quectel EP06 IEMI and need the steps if anyone knows how.

However, if it gets wiped out during a bad flashing process, then it could be REPAIRED with the SAME IMEI as printed on the modem's label. I've read that a failed flash, or the proper test command can potentially wipe the NVM, or via a challenge/response:
AT!OPENLOCK?
The encryption key must be calculated based on the above challenge response, then entered via:
AT!OPENLOCK="xxxxxxxxxxxx"
AT!NVIMEIUNLOCK
For example, if the imei repair is 12345678901234+<check-digit + 0 padding>
The check-digit can be calculated using this LUHN calculator > https://planetcalc.com/2464/
So the repair command in this example with the calculated check digit 7 + 0 padding would be:
AT!NVENCRYPTIMEI=12,34,56,78,90,12,34,70
FYI. Changing imei in the US is illegal (there's a federal statute against it, and Big Bubba's waiting for ya in jail lol), however repairing it with the original imei should be ok, though it's a gray area. Just to be clear, the above is for information purposes only, I do not condone the use of it in any shape or form.
This is the modem telling you that you are not privy to change this secure item the way you are trying to change it is trippingSudoroyal wrote: Sat Nov 09, 2024 10:53 pm everytime i try to repair my imei the sierra card powersdown and kills my serial connection to it.
