Some users have been having a lot of problems with the HTC dev bootloader unlock method. Not only does it not completely unlock the bootloader, but it causes problems with flashing things such as kernels and radios.
This problem is especially present on the HTC Sensation, who suffer from issues such as not being able to flash some radio files and some kernels, unless installed in a specific manner, can cause some problems such as WiFi problems.
XDA Senior Member tkraaa has has taken a deeper look at some of these problems and, more important, ways around them or ways to fix them along with links to more threads that can help fix them. Here’s tkraaa’s take on the WiFi issues:
it allows you to install Custom Roms , But what htc don’t tell you is that the custom rom should be using their htc Stock kernel in order to work without errors !!!!!!! . ( Otherwise for Roms with custom kernels , you have to install Custom Kernels in a certain Method to avoid errors like WiFi error !!!! )
So, if you’re facing some of these woes and need them fixed, you can check out all the fixes and explanations in the original thread. Additionally, you can find links to other threads that deal with these problems as well in case you need them._________
