hello guys. I have a problem , yesterday my phone could boot up. So i decided to check it out. I pressed volume up , centre button and power button , it opened that menu , i tried to hard reset that. There was a fail like "failed to mount /cache(invalid argument) and i could do any of the choises of the recovery menu. So i thought that i have to install the firmware of the phone again (i have samsung galaxy j5-smj500f). I found the right firmware from sammobile.com and i installed it with odin3. After the installation i am trying any button combination but i won't turn on. Any solutions ?
