Disclaimer: This technical paper is for informational purposes. Modifying firmware voids warranties and carries the risk of "bricking" the device. Ensure you verify the specific sub-model of your E173 before proceeding.
This guide is for flashing and unlocking the Huawei E173 (specifically Megafon E173u-1 models) to firmware version 11.126.85.00.209_B427, which makes it universal (compatible with any SIM) and provides a "portable" (Mobile Partner) dashboard for easier management. ⚠️ Pre-requisites & Warnings Backup: Flashing may erase data.
Safety: Do not remove the modem or turn off the computer during the upgrade.
OS: Use a Windows 7/XP computer if possible, as newer Windows versions might not support the older flasher tools.
Codes: You will need a Flash Code and Unlock Code (Nck) for your specific IMEI. Phase 1: Preparation (Get Your Codes)
Get IMEI: Remove the plastic cover of the Huawei E173 to find the 15-digit IMEI number.
Generate Codes: Use a Huawei Unlock Calculator (e.g., v4mpire_unlocker or similar) to calculate: Flash Code: Required to flash the firmware. Unlock Code (NCK): Required to unlock the SIM lock. Note: Save these codes. Phase 2: Firmware Upgrade (11.126.85.00.209)
Prepare Modem: Remove the SIM card and MicroSD card from the modem. Connect: Plug the Huawei E173 into your PC.
Run Flasher: Download and run the huawei_e173_e173u 1_firmware_update_11.126.85.00.209_B427 file (often found in forums like 4PDA or 3Ginfo.ru).
Flash Code: When prompted, enter the Flash Code you calculated in Phase 1.
Wait: Click "Update" and wait for the "Download to DataCard" process to finish (can take ~30 minutes). Do not interrupt.
Finish: Once the green checkmark appears, the firmware is updated. Phase 3: Unlocking & Installing Dashboard
Unlock: Insert a non-Megafon SIM card. Connect the modem. It will prompt for an unlock code. Enter the NCK (Unlock) Code generated in Phase 1.
Dashboard Update: To change the interface to generic Mobile Partner (portable dashboard), download and run a suitable Dashboard update (e.g., UTPS11.300.05.15.143_MAC11.301.09.01.143). Optional: Set "Modem Only" Mode
If you are using the modem on a router or Linux, you may need to disable the virtual CD-ROM/SD card features.
Use a terminal program (like PuTTY or HyperTerminal) and send this AT command:AT^U2DIAG=0 Troubleshooting
SIM Not Detected: Re-flash with the same firmware, or try a slightly different version.
Flasher fails: Ensure all Huawei software is closed before running the updater. If you want to know: Where to find the specific files (like E173Update.rar) How to fix "SIM/USIM card not detected" How to re-lock the modem if necessary
