I try to run SP Flash Tool under Ubuntu MATE but after I chmod +x the executable file, I get this error:

bash: ./flash_tool: cannot execute binary file: Exec format error
bash: ./flash_tool.sh: Permission denied

Anyone have any idea why?

The Exec format error means you are using the wrong file for your computer. Most likely you were trying to use the 64 bit version on a 32 bit Ubuntu. You need to download the right one.

Type arch in a terminal to be sure which you should use.

If you get something like i386 as I suspect, download the "Linux 32 Bit version" under the heading "Direct links for SP Flash Tool Download" from http://spflashtool.com/

Currently, the supposed 32-bit version hosted there is in fact also 64-bit, and so no usable version is available for 32-bit Ubuntu. You might be able to find a 32-bit one elsewhere, but be careful. You cannot be certain any of these downloads (including the above link) are virus-free.

If you get x86_64 choose "Download SPFlashTool for Linux - 64 Bit Tool"

  • chmod +x flash_tool.sh ./flash_tool.sh ./flash_tool.sh: line 13: /.../SP_Flash_Tool_Linux_v5.1520.00.100/./flash_tool: cannot execute binary file: Exec format error

  • type file flash_tool while in the same directory as flash_tool.sh. Does it say it is ELF 64-bit?

The Download for 32bit Linux on http://spflashtool.com/ is not 32bit, it is the 64bit Version.

  • @Pierre.Vriens You might get this error is you execute the 64 bit version on a 32bit OS.

Run it as non root user. I'm on Kali Linux with root user by default and I was able to run the flash_tool using a non root user , through gksu:

<< gksu -u my_non_root_user ./flash_tool.sh >>

On Ubuntu it should work without sudo I suppose.

That works for me. I hope it may help!

  • That won't help. It's the wrong executable type for the system in question and unrelated to super-user privileges. See the other answers. -1
