- You can flash the TWRP Recovery in this guide on the Samsung Galaxy A7 with the model number SM-A710Y.
BEFORE WE BEGIN
- The TWRP Recovery file in this guide is an unofficial release and not given by the official crew from Team Win. The recovery file is given by an XDA Developers senior member and the comments on the thread say it is working. With that being said, the OP states you should head over to the Sam Mobile website and get your stock ROM ready to flash just in case you do suffer from any soft-brick issues.
- Download the Samsung USB Drivers  on the Windows computer before you start the guide so your smartphone can talk to your Odin flashing tool.
