coming from the installer.app, under system category i just install this. i want to know my bootloader version and other info..

after installing MY SIGNALS FAILED... "nothing on my signal bar" even NO SIGNAL word.

I panic coz i dont want to restore my phone. so i just uninstall the program. then Manually check thru winSCP the folder so it will remove completely. Now gone..

REBOOT my phone...and my iphone back to normal.

Just wondering what happened? what program can i use in my PC for TERMINAL? im trying to see my bootloader version thru winSCP terminal but wrror in command. Can anyone share about this and what happened to me. im not familiar with this program
