TWRP is an open source, community project. TWRP development is done by roughly 4 people at this point. We also have a large support community with many people who are willing to answer questions and help people with their devices either through our IRC channel or on forums like xda-developers.
Team Win was originally formed to work on porting WiMAX to CM7 for the HTC EVO 4G. After our work on the EVO 4G we wanted to work on a project that would work on more devices than just the EVO 4G and we settled on working on a recovery. Today TWRP is the leading custom recovery for Android phones.
A custom recovery is used for installing custom software on your device. This custom software can include smaller modifications like rooting your device or even replacing the firmware of the device with a completely custom “ROM” like OmniROM
You can find the source code for TWRP at github.com/omnirom/android_bootable_recovery/
2.7 marks the first time that we are dropping support for older devices. We are doing this because of the SELinux support needed to install 4.4 Kit Kat ROMs. The non-TWRP parts of the recovery image have to be built in at least a 4.1 tree and the kernel that is included in the recovery image has to support writing SELinux contexts. We don't own most of the devices that we support so we depend on outside testers and developers to help us update devices. In many cases we can't find someone readily. Come to #twrp on Freenode if you want to help bring your device up to date. You can tell right away if your device will support 4.4 ROMs in 2.7. Boot TWRP and press the console button (the square-ish button either in the bottom middle or upper right) to view the console output. If it doesn't say "Full SELinux support" in the console, then your device still needs some work. Help us help you.
