Is it possible to flash a .DZ stock ROM on a LG Android phone (Doubleplay / C729 / Flip II) that doesn't fully load (T-Mobile logo repeats itself)? If yes, how exactly?


  1. Recovery mode has no options, it only displays an unpacking icon for a few seconds.
  2. USB debugging is not enabled.
  3. USB connection with PC is stable and working.
  4. A .DLL file is included with the .DZ file.

Thank you!


There is currently no way to do this.

Where did you get the .dz file from?

You would have to ask the prividor to provide a .kdz file as well as the .dz file so you can flash with the KDZ Updater program.

  • The .DZ ROM is the only ROM for LG C729 (Doubleplay) that I was able to find, so there's no provider. – Key-Six Dec 13 '12 at 13:54

Have you tried using this update tool? It should do the work if it can connect.

  • Yes, I've tried it, but it accepts only .KDZ files, not .DZ – Key-Six Dec 13 '12 at 12:23
