How to unlock Huawei E5573Cs -322 / 609 / 931 Mifi

Credits hovatek forum
This is a step-by-step guide on how to unlock Huawei E5573Cs -322 / 609 / 931 MiFis. These types of MiFis do not support unlocking by generating NCK code using IMEI so you’ll need to unscrew the modem down to the board for a bootshot.

This guide doesn’t seem to work on devices running on the latest firmware versions i.e 21.326.xx, 21.327.xx, 21.328.xx and it doesn’t work on the Huawei E5573Cs-933 model

Why would I want to unlock my MiFi?

You might have purchased a branded MiFi which would normally be locked to a single network. This does not mean it can’t support SIMs from other networks. The process of unlocking enables you use the MiFi on other networks’s SIMs so you can switch at will depending on your budget and location.

Requirements

  • A PC running on windows 7 for best outcome
  • USB cable
  • A thin piece of copper wire to bootshot
  • Download all software requirements @ https://drive.google.com/open?id=0B4S-Z7…npXMjBMdmc (Swift-E5775, Balong usb downloader, usbloader-5573cs-322, E5573cs_Update_21.318.03.00.00, E5573cs_Update_21.318.99.03.00, Update_WEBUI_17.100.15.01.356_MRE5)
  • Specifically for E5573Cs-931, download USBloader

Important Notice

  • If your model has a high firmware version (e.g 21.326.xx, 21.327.xx, 21.328.xx, etc), this guide will not work for you. You can try flashing unlocked firmware for your model
  • Unlocking doesn’t automatically mean that all SIMs will work on the MiFi. The SIM’s band needs to match that supported by the MiFi.
  • This guide can also be used to unlock certain Huawei E5573Cs models (e.g e5573cs-322, e5573cs-609, e5573cs-931) by MTN, Airtel, Spectranet, n-Tel, Idea e.t.c
  • Do not disconnect the device from the PC until you’ve flashed the last update file so as not to encounter driver issues.
  • If you wish to unlock the MTN MiFi device E5573s-320, then see https://forum.hovatek.com/thread-16008.html
  • The WEB-ui included has the idea 4G interface but it has an extra feature which the default interface doesn’t (USSD feature i.e you can dial USSD codes directly from the device)
  • If you wish to use the default Huawei interface, then you can download @ http://www.mediafire.com/file/9hkwich758…eneral.zip
  • If you used the Idea 4G dashboard and you encounter an error while trying to install, simply use the default huawei dashboard provided in the link above
  • If after following the entire procedure and your device seems bricked (i.e blinking the two green lights) , then simply install the E5573cs_Update_21.318.03.00.00 firmware again then restart your device. The device should now work properly.
  • The default WiFi password after unlock is 12345678 . If this doesn’t work then power on the MiFi and connect to PC via USB. This will enable you access dashboard where you can reset WiFi key
  • After flashing usbloader successfully, the reset button on the mifi will no longer work

Unlock and enjoy
