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

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.


Yes. it must be boot partition. you need JTAG flashing solution to fix you phone


Can you explain please? Never worked with JTAG, but I'm sure I can handle it if you point me. Thank you.
