Let’s Define first what is Android Firmware and ROM

Read-Only Memory (ROM) is the firmware (Operating System) stored in the internal memory of the device. Then firmware and ROM can be interchanged, When a mobile technician said ROM or Firmware, they are referring to Flash File which you can be downloaded below. Android Firmware has a different version and ROM has a different type. More info about Mobile OS.

Why we need Firmware

We need firmware to our smartphones when we experience software problem and if we want to update or Upgrade. The following are the common software problem that can be fixed after a successful flashing of firmware:
  • Infected Virus – Also known as Monkey Virus, It is when you connect to Internet, there is automatically download and install unknown apps or some popup screen and sometimes automatically turn on WiFi or data connection without doing it. The virus will not remove though hard reset or formatting your phone. Installing new firmware is the best solution.
  • Unfortunately Error – This is when you open some apps it will popup Unfortunately, App has stopped this is due to downloaded malware app. If cannot fixed through clearing the data, then flashing new firmware is also the solution.
  • Stuck or Hang in Logo – The reason for this is either when you install incorrect Rom or Encounter problem in Operating System. Try to hard reset first but if still stuck, then flashing firmware is also the solution
  • Too Many Pattern Attempts or forgot password – This is just an alternative solution if you cannot hard reset your android phone.
  • Dead boot – Another caused of flashing incorrect ROM will lead to dead boot. Make sure you are flashing the right ROM (Firmware) for your Phone. If you think below is the right firmware for your device then nothing to worry.
  • Boot Loop – The device keep rebooting when you turned it on, Unless your power switch has been damage, Flashing new ROM will fix it.
  • And any software problem.

Things to consider before flashing

  • Back Up Important data – We strongly recommend this to avoid further problem. Complete flashing Rom will erase all and bring back to the default app. All files saved in internal storage will erase like Contacts, Photos, Messages, Accounts, and installed third party application.
  • Battery Must be charged – Recharge your battery at least more than 30% to avoid interruption during flashing.
  • Windows PC and USB Cable – Windows 7 32/64 bit is our recommended PC for compatibility of drivers below.
  • Back Up Installed Firmware if necessary – This is optional if you want to restore your firmware after flashing. Doing this back up need some special tools depend on your mobile chip set.
Flashing firmware may bricked or unbricked your phone, Its always Do It Your Own Risk. We  shared tested firmware and if you follow the instruction correctly and choose the right ROM for your phone model then no further problem will be encounter.
