Recover formatted partition in ROM

I formatted partition number 3, I have back up of it. But the device is never turn on after it, and it is not recognized by PC.

I guess I need to program the ROM memory.

How can I do it, and which tools, devices should I use?

Hello Kostya Kostyushko,

  • Run Odin flash tool,
  • put your phone in to download mode (vol down/home/power button) and connect to PC via USB

* Tick re-partition box on odin tool

* Click PDA and select your stock official Samsung ROM

  • Flash and wait for reboot

You have to find Correct ROM and Odin tool for S5 Active.

Note : All data will be lost on your user data partition as you re partition the ROM & . Flash your device at your own risk.

Hope this answer help you to fix your dead S5

Cheers!

This is a problem as I mentioned in my question, the device is never turn on. It means, I can't put it to Download mode.

I'm not sure what the 3rd partition is responsible for, maybe boot loader? But it seems I messed up this time.

Even if I connect the charger, it is not have any reaction. Completely dead.
