To identify your module's current IMEI, you can use the standard AT+CGSN or AT+GSN commands. AT+CGSN Response: 860195057712345 2. The Repair Command ( AT+EGMR ) quectel change imei

Changing or repairing the International Mobile Equipment Identity (IMEI) on Quectel modules like the EG25-G or EC25 is a specialized task typically reserved for authorized repair or development scenarios. While technically possible via specific AT commands, the process is heavily restricted by firmware and local laws.

  1. Thanks for the article, Yahya. I just opened EAGLE for the first time in a while and saw the notification with the jump from 7>8. I googled “eagle cad differences version 7 to 8” and this was the first article that came up. It was exactly everything I was hoping to find. Thank you.

    1. You’re welcome Scotte. I’m glad that it was exactly what you’re looking for. even that Autodesk has brought a lot of new features since the time I wrote the article, however you can easily follow the new features in the official website.

  2. Hello Yahya,
    Thanks for the article.
    What are the reasons to stick around with EAGLE and not switch to Altium, which is pretty well-known as an industry standard software.

    1. Actually nothing 🙂

      As an old user of Eagle and personally, I find it time consuming to switch to another CAD tool while the current tool Eagle do the job right now.

      Generally, I advise all beginners to start with Altium. It’s indeed professional, but in the same time I think also that Eagle CAD under the heavy development from Autodesk team will have a brilliant future with these steady steps.

      Thanks for the question my friend Siraj 😀
      By the way: I started tinkering with circuit studio (the hobbyists version of Altium)

  3. Hello Yahya,
    Thanks for your article. Can I ask you something?
    How can I proceed a part of my .brd design which already finished.
    For example, I have preamp and main amp in one .brd where separated with straight line of ground (so its become 2 blocks). Now I intended to proceed that .brd to the next step but only preamp side with FlatCam.
    Is it possible? How can I make it?
    Warm Regards,
    Thank you

    1. Hello Eka

      While your design is already separated into 2 blocks, why you just delete the main amp part or to copy the pre-amp part into a new PCB and then process it with FlatCam? Just to understand your case here.
