Repair manuals help you fix HTC EVO yourself
If you view a hardware issue or broken part on your HTC EVO 4G as a challenge for your DIY skills, then make sure you bookmark iFixit's EVO repair manual.
It includes 12 step-to-step guides to fix a range of problems from very simple things like replacing a worn-out battery to more complicated projects as replacing the logic board. Most of this could be gleaned from iFixit's complete teardown, of course, but these guides make it easier to find exactly what you're looking for. Need to replace the front camera? Check out the Front Facing Camera guide. Simple as that.
These guides would also be useful for hackers/modders, though I guess the hardcore ones could probably disassemble and reassemble the EVO with their eyes closed by now.
