What is the original android firmware

firmware is the applications and operating system of your mobile that control how a Smartphone operates. It’s called firmware rather than software to highlight that it is very closely tied to the particular hardware components of a device. Also, some mobile phone manufacturers have OSes that we can’t do any modifications to the system partition. But, when it comes to Samsung they are allowing you to do any modifications to your phone easily. In this post, I will explain how you can install the original firmware on your Samsung T285YD tab (Samsung J max)

 

Why do we need to flash original firmware on our device?

There are many reasons to flash your original firmware once again.

  • Fix boot errors on your phone

If you have done anything wrongly to your original operating system, it will lead your device into the soft brick state. And the result will your device will be stuck on the booting screen or boot logo. That’s the simplest meaning of soft brick.

  • What are the things that your phone leads to the soft brick state?
  • Flashing unauthorized firmware, zip files, boot, or system files that not mentioned or ported to your device
  • Trying to root your phone without unblocking the FRP lock or bootloader
  • Flashing wrong kernels or custom recovery files
  • Change, modify, or delete the system files with root access
  • Giving root access to some apps that modifies your system partition using scripted methods (All most all of these type of apps will give you a warning)
  • And more…     
  • To reinstall the original firmware when you are facing some errors of custom ROM 
  • To get a cleaned system/boot/recovery partitions
