Request ADB and Root Login Password

Could you please provide the login password for my EG21-AUX?

Here is the login prompt I met.

mdm9607 login: root

quectel-v : v1.0

quectel-ID : 33178484

Password:

For security reasons the community won’t be able to provide root/ADB passwords. If you legitimately own that EG21-AUX module, the correct and safe routes are:

  1. Check the module’s quick start/user manual or the firmware release notes — manufacturers sometimes document default credentials (if any) there.
  2. Contact Quectel support or your vendor with the module’s serial/IMEI and proof of purchase; ask them for the proper recovery procedure or the official firmware/flash tools.
  3. If the device shipped with a carrier image, ask the carrier/vendor — they sometimes lock devices and control credentials.
  4. Don’t post any passwords or sensitive console output publicly here — share them privately with official support only.

If you want, I can help you draft a short support request to Quectel (include model, quectel-ID shown in your prompt, firmware version if known, and where/when it was purchased). Example template:

Subject: Request for ADB/root access recovery — EG21-AUX (quectel-ID: 33178484)
Hello Quectel Support,
I have an EG21-AUX module (quectel-ID: 33178484) and I need assistance recovering ADB/root access. The login prompt shows mdm9607 login: root and quectel-v : v1.0. The device was purchased from [vendor] on [date]. Please advise the official recovery procedure or any required files/proofs. Thank you.

Hi! Thanks! I need two more root login passcodes — both of them are EG21-AUX, with Quectel IDs 28191675 and 27282805.

I can’t log in with the code you kindly provided me. What am I doing wrong? Maybe I need a special firmware version?
