The Team Win Recovery Project has been picking up major steam for awhile now. And since its update to version 2.1 that we covered not too long ago, it’s been getting closer and closer to being one of those must have recoveries on newer devices. Unfortunately however, not every device has made the list quite yet. That doesn’t mean it can’t be.
Samsung Epic 4G Touch users have been clamoring for a TWRP 2.1 release for some time now, and XDA Recognized Developer Dees_Troy wants all the Epic Touch users know that Team Win is listening. While Team Win can’t personally get the recovery working on the Epic Touch, as they don’t have the Epic Touch to test it, Dees_Troy wants to spur the device’s already vibrant development community:
The TWRP source code is all public, including the GUI. It’s pretty easy to compile and work with and we have a nice guide to help you out here: http://tinyw.in/nP7d
If you need help integrating TWRP into your builds or have questions about compiling TWRP, feel free to find us in #twrp on Freenode.
So this begs the question, why the complicated response from Team Win? Well the answer, as expected, is rather complicated as well. As with most Samsung phones, there isn’t a proprietary recovery partition. Or rather, as Dees_Troy calls it, they don’t use a proper recovery partition. What actually happens is that the recovery is packed into the boot.img. This means that whenever a user installs a new kernel, they’re stuck with whatever recovery comes with that boot.img. As many Epic Touch owners will tell you, there’s a few different recoveries roaming around depending on which kernel you flash. This makes porting the recovery a little more difficult than normal because you not only need to port the recovery so it works, but you also have to compile a kernel in which to pack it. So, Team Win has made the code available for anyone who wants to go through all that for the Epic Touch.
