How to Unlock Huawei E5573 ? The Free trick!

How to Unlock and Restore Orginal IMEI & S/N of Airtel's Huawei E5573s-606 Firmware Version 21.315.XX.XX.XXX. I could see lot of paid services for unlocking, but not any free ones and atlast after some deep googling, I explored a way to do it for free. Its so simple, just follow the below 4 steps.

Step 1)

• Goto https://huaweicodecalculator.com/new-algo/ and signin with a Google account. 
• After Signing in, you’ll be asked for IMEI Number which you can find out from the Huawei product Box or within the device (Try removing the Battery). 
• Model is nothing but E5573. Once you click on calculate, you’ll get a flashing code which is your password to actually update your device firmware. 
• Save this password somewhere safe (we will use that in step 3) and proceed to step 2.

Step 2)

1. Now Download the below two drivers (Yeah! Both of them).
2. Huawei_E5573s-606_Firmware_21.110.99.03.00_general.7z and
3. Huawei_E5573s-320_Firmware_21.180.17.00.00_general.7z
4. Download and extract it using Winrar / 7zip

Step 3)

• Connect Huawei E5573s-606 device to your PC and Run ‘P711s-E5_Update_21.110.99.03.00.exe’ from the first extracted zip file content (Huawei_E5573s-606_Firmware_21.110.99.03.00_general).
• Use the password saved in Step1. Wait patiently for the whole process to complete with a success message. Once you get the success message, disconnect the device, remove the battery, and then re-insert the battery and turn it on.

Step 4)

• Connect Huawei E5573s-606 device to your PC and Run ‘E5573_Update_21.180.17.00.00.exe’ from the second extracted zip file content (Huawei_E5573s-320_Firmware_21.180.17.00.00_general).
• Wait patiently for the whole process to complete with a success message. Once you get the success message, disconnect the device, remove the battery, insert the new sim, and then re-insert the battery and turn it on. Once device is connected, goto 192.168.8.1 from your browser.

Note: The above steps worked for me perfectly. If you are brave enough, go ahead and give it a Try. In case it doesn’t,  I’m not responsible for any damage caused to your device. I’m not selling any unlock code, and this blog post is just an experience sharing on how I unlocked my Huawei device. Beware of the fraud secret code/unlocking service, Think before you take any Action! Please do not blame me for your actions!
