I am new to all this android stuff and wanna learn how to fix / modify them at some point.
Because I have a LG Ultimate 2 trackphone that somehow is messed up (have bootloader error and can't run almost any apps I install).
I didn't try modifying anything but the only thing that I know that happened is when I plugged in a charging cord it kept beeping, I  finally looked at phone and seen what was happening and unplugged it. Then my problems started.
So if anyone can point me in the right direction to a very good starting point I would appreciate it. I'm a total newbie !!!!
Thank you in advance !!!!
