Airtel India has recently launched a new Huawei‘s Mobile WiFi router, the E5573s-606 (Huawei E5573). It comes with customized firmware and there is no option to enter the unlock code. When you will change the default SIM card of Airtel with any another network, then it will show already used 10 codes and attempts to try is 0. It runs on the firmware version 21.180.17.01.284. You can also check the firmware version of your device.

Airtel E5573s-606 Huawei UnlockAirtel’s Huawei E5573s-606 mobile WiFi router can be unlocked after the firmware upgrade.

Before proceeding with firmware upgrade, download the following required files :

1. Huawei E5573s-606 Firmware ver 21.110.99.03.00 general and Huawei E5573s-320 firmware ver 21.180.17.00.00 general.7z from https://routerunlock.com/download-huaweis-e5336-e5573-and-b593-firmware-and-webui-free/

2. Huawei hilink drivers from https://routerunlock.com/download-huawei-hilink-modem-drivers-free/

3. Firmware code you can generate from Universal Master Code tool or comment with model and IMEI to get it.

How to Unlock Customized Airtel’s Huawei E5573s-606 Mobile WiFi Router :

1. Connect your Huawei E5573s-606 router to PC or laptop via USB cable.

2. Make sure that your router is charged at least 50%.

3. Extract the zip file Huawei_E5573s-606_Firmware_21.110.99.03.00_general and run P711S-E5 update_21.110.99.03.00.exe.

Note: If you are getting “Error 10: Find port failed” then refer this post to rectify the problem. If your PC is not available under COM ports then run this registry file and restart your computer.

4. It will ask a password. Use flash or firmware code as password.

5. Input the correct firmware code and wait till finish process.

6. After successful flashing of the device, switch off the router or remove the battery and re-insert battery in the device and turn it ON.

7. If it is not detected by PC due for drivers problem then update the drivers (You have already downloaded Huawei Hi-link drivers).

8. Now, download DC unlocker from here or any another source (latest version).

9. Detect the device under DC unlocker.

10. Go to the end of the result.

11. Now type “AT^NVRDEX=50503,0,128” (without quotes) and press enter from the keyboard.

DC with commands

12. Now, it will show NV codes in hash format. Pay Rs. 300 (if from India) or 6 USD (if from outside, then use PayPal button) and mention the details, I will contact within 8 hrs. Hash code will be converted into the unlock code / NCK and will be emailed back to you.

Note: After getting the code through email, proceed with further steps.

13. Now, extract Huawei_E5573s-320_Firmware_21.180.17.00.00_general.7z file in a folder.

14. Run the firmware setup file again. During this period, it will not ask the password.

15. Wait till firmware successfully installs in the device.

16. You will notice that all light are turned ON, including battery light and network light.

17. Open web-browser (Internet Explorer) in PC and browse for 192.168.8.1.

18. Login to device router panel (username and password are admin).

19. Here, you will see, your device have 10 unlocking attempts left.

20. Just enter correct unlock password in a router and your router will be unlocked.

Note : Don’t try to enter any wrong / free unlock code into the router, otherwise it will be locked permanently.

Generating unlocking code was not so simple task, a very big thanks to Balwinder Singh for sharing images and tips about the unlocking.

Note : This firmware process is mandatory for all the Huawei E5573s devices.

Update : Various people are facing driver problem in Windows 10 /8 / 7 / XP PC. For that, download the latest Huawei Mobile Partner, install in PC, and now restart the PC. All Huawei drivers will be updated successfully. Now, you can proceed with further steps.

Update: Airtel is now providing updated Huawei E5573s-606 MiFi router. It comes with firmware version 21.315.01.00.284 and WebUI 17.100.14.00.284. It can be unlocked with above method, after shot of boot. Unlocking of Idea E5573s device is also possible after shot of boot. The procedure is same as Airtel E5573 unlocking.

Update: Airtel and Idea have recently launched Huawei E5573cs-609 in India, both devices can be unlocked.

  1. sir,please help, firmware update is succesfully,but my E5573s-606 AIRTEL WIFI MODEM is not visible ,not conect,pls help me sir,my whats app number 9655693609,

  2. My imei no is 866079021326167. model no. e5573s-606. i have try to unlock with new algo and old algo but is not a write code. so i need the write simunlock code

  3. Sorry I do not think this the right method as it is bricked only after following your method. Also many other problem have similar problem as I can see in the forum discussion. Please check and give the solution.

    • Sorry Kamlesh. I was actually doing in a wrong way.I did as you directed today in proper way and now it all fine.Thanks a lot.Sorry to be rude before.

  4. dear all after lots of efforts and getting errors esspecially “error code 10” on my windows 7 OS, several times, finally Just now I had successfully unlocked my AIRTEL MiFi 5573s-606. PLEASE NOTE: Only V4 Algo Unlock code works with these MiFi.

  5. As a Nowise in all these, I had tried hundreds of options that I got
    from google search, but non of them worked for me and at last I got
    frustrated with “Error Code 10, Find Port Failed”, But one thing I
    understood was that this error code 10 was due to different types of
    drivers installed in my laptop. I also tried with Ubuntu way, but
    couldn’t. Hence finally I tried my own way, the hard way, After backing
    up all my datas, I completely formated my laptop and installed Windows 7
    (Fresh copy), then without updating any of the drivers (Including USB
    drivers), I tried to flash my MiFi using backed up downloaded firmwares,
    guess what ??? I didn’t got any error code 10, and I successfully
    flashed my MiFi with non-customised firmware.
    For complete unlocking
    proceedure (100% free and working) visit this link:

    PLEASE
    NOTE CAREFULLY, the first step, its important, or else you may not be
    able to generate Hash1 & Hash2. Only Flash the non-customised
    firmware relevant to your MiFi model, ie., if you are having E5573s-606,
    then flash it with
    “Huawei_E5573s-606_Firmware_21.110.99.03.00_general”, in first step,
    and if your MiFi model is E5573s-320, then in first step flash it with “Huawei_E5573s-320_Firmware_21.180.17.00.00_general”.
    Once
    you successfully flashed your MiFi, then you are good to generate Hash1
    and Hash2, Your MiFi may not be visible after flashing, for that you
    just download and install 1) “Drivers_v.4.25.11.00” and then 2)
    “Drivers_v.5.01.06.00”. Now using “Huawei_2015_Code_Reader”, you can
    generate Hash1 and Hash2. Once you get both of these hash, write both in
    a word file with “CAPS ON” and add one space between each two
    alphanumeric letters, at the end, you must get 32 plus 32 pairs (If you
    had done everything correctly). Now copy these 32 + 32 (64 pairs) into
    and generate your UNLOCK CODE,

    Now once you had got your v4 algo unlock code,
    Flash once again your MiFi with the other non-customised Firmware ie.,
    if in first step you had flashed it with “606” firmware, then now you
    need to flash it with “320” version firmware,and vice-versa. To do so
    you may need to first instal .net framework 4.5 or later. Once you had
    successfully flashed your MiFi for second time, then connect MiFi using
    USB cable after inserting a non-supportive (Other network) SIM. Now you
    will be prompted for Unlock code, just put your generated v4 algo unlock
    code. Now your MiFi is unlocked for life time. This proceedue is
    applicable to all latest MiFi’s.

  34. Hi Kamlesh,
    I’ve bought two of these unlocked from amazon.in but both of them are exhibiting a similar problem with regards to charging the battery. After more than 5 hours of charging the battery its still at 75% and drops to 50% within 3 minutes. No matter how much time its charged, the charge does not go beyond 75% and drops immediately. Initially I thought its a battery problem and asked for a replacement. But the replacement is also acting the same way. It looks new and its date of import is 08/2016. The battery has a date stamp of 07/27. Is this a battery issue or could this be related to the unlocked firmware?. The firmware is 21.180.17.00.00. Other than this problem, the device is working great with my Idea sim.
