Soon after launching the E5573 (E5573s-606) router by Airtel, now Idea India is also providing the same model to his users. Unlocking is similar to Airtel’s Huawei E5573s-606 router but after the boot shot. The funny thing is that Idea E5573s-606 also comes with customized firmware, means after changing the SIM, it will redirect you to the unlocking page, but attempts will be 0 to enter the NCK / unlock code.
Now you have understood that what I want to tell. To unlock this device, you need to change the firmware.
Before proceeding with firmware upgrade, download the following required files :

5. DC Unlocker.
