Hello,

I am experiencing an issue while trying to unlock my Huawei MiFi E5577Es-932 using DC-Unlocker. Below are the details and steps I have followed:

1. Device Information:
   • Model: Huawei E5577Es-932
   • IMEI: 868778033270226
   • Firmware: 8.0.1.1(H335SP1C1367)
   • Dashboard Version: UTPS22.001.29.01.03
   • Web UI Version: WEBUI_801.999.31.1.1367_MRE5
   • SIM Lock Status: Locked (Card Lock)
   • Unlock Attempts Remaining: 10
2. Steps Taken:
   • Connected the MiFi to my PC via USB.
   • Installed Huawei HiSuite to ensure drivers are properly set up.
   • Launched DC-Unlocker 2 Client (Version 1.00.1442).
   • Selected "Huawei AuthVer 4 modem (New)" as the model.
   • Detected the modem successfully, as the application recognizes all the details.
   • Purchased credits to unlock the device.
   • Attempted to unlock the device.
3. Result:
   • After initiating the unlock process, I receive the following error:
     "No response! Error code 21. Unlock failed!"
4. Questions:
   • What does "Error code 21" indicate?
   • Are there additional steps or configurations required to unlock this device?
   • Could this issue be related to the firmware version (8.0.1.1(H335SP1C1367)), and if so, what is the recommended solution?
   • How can I proceed without losing the credits I purchased?
5. Additional Notes:
   • The device is detected correctly, and no wrong unlock codes have been entered yet.
   • I have access to the necessary tools and software to troubleshoot further if needed.

I am concerned about losing the credits I have purchased and would greatly appreciate your assistance in resolving this issue. Thank you in advance for your help!

Could you please guide me on the following:

1. What are my options with the credits I’ve purchased?
   • As I am unable to use the credits for unlocking my device due to this limitation, I would like to kindly request a refund for the credits I have purchased, as they are not usable with my current device.
2. How can I change or downgrade the firmware on my Huawei MiFi E5577Es-932?
   • Is there a recommended method to downgrade or update the firmware to a version that would be supported by DC-Unlocker? If so, please provide the details or tools required.

I would appreciate your assistance in making use of my credits and helping me unlock my device.
