In the earlier models (E5573s), when you need to change the firmware, there was a need to enter a code known as a device Flash code. This flash code was easy to calculate for the Old models based on the IMEI number as the algorithm used was either Algo V1,Algo V2 or Algo V3. However the latest model, E5573Cs, uses the Algo V4, which requires a code, called DataLock Code. This code cannot be calculated using IMEI number easily. Also Airtel does not provide this Code at all. Hence, to change the firmware, we need to Remove this code entirely. This DataLock Code is stored on a space called the NVRAM (Non -Volatile RAM), along with other data like your Device Serial Number, Device IMEI number, Wi-Fi default SSID, Wi-Fi Default Password. Hence Using this method, will also delete all these other Data as well. In the post I will Also show how to restore this data.

However, please be informed, this post is t share the knowledge, and all responsibility of performing these steps is on you. Your device will loose its waranty and it cannot be restored easily. Hence, I will not be held responsible for any damage.
