Android Troubleshooting and Development

Almost every android geek has heard about "flashing" a custom ROM on their device. And digging a bit deeper reveals that flashing also has two types. "clean" flashing and "dirty flashing" But what's the difference and which one should you choose? To find out, read ahead. The difference A clean flash is what you do when, you install a ROM after wiping all your device partitions (System, data, ART/Davlik, and cache) A dirty flash is done when you flash a ROM over an existing one, without erasing the system partition.

BAM your device crashes and doesn't boot up. But can you fix it? YES (obviously) Do you need to factory rese...
