The lead developer of TWRP, Ethan Yonker (Dees Troy over at XDA), just let it be known to us that TWRP recovery is now available officially for some four Android devices today. That list of devices includes Galaxy J7, Sony Xperia Z3 Compact, Oppo R7 Plus and lesser known Cat B15q.
The installation method may differ on these devices, so if you are looking to install TWRP on any of these devices, proceed with caution. Make sure you know what you are doing.
