not directed at anyone in general...
just wanted to say that u dont need flashtool to flash kernel first of all...
if ur bootloader's unclocked, all u need is fastboot command line files available for both mac and pc.. u can get that from android development toolkit or just google how to use fastboot... u'll find several kits (with adb, etc)..
its the same old way to flash kernels n such for almost every android phone
u can use flashtool too.. it maybe easier (i've never used through)... in anycase, make sure fastboot drivers are installed (from the drivers folder of flashtool) and if u're on windows 8, then refer to FAQ from flashtool website... u'll need to disable driving signing on windows 8 to be able to install most drivers..
either way, u need to power off ur phone, connect to usb with the vol key up in order to enter fastboot mode on ur phone first and foremost... fastboot mode will have a blue led lit up on ur phone.... otherwise flashtool, drivers, fastboot commands are all gonna fail.
would help to read up on stuff before trying stunts.. or when things fail, google error codes and situations.
dont just post on xda and expect someone to magically help u... makes u less prepared for future stunts and u may end up bricking ur phone or worse...
just saying it out loud to all those u keep posting they cant get their bootloader unlocked ZU rooted.
and just coz i'm tired of the way ppl just post stuff without even reading a page before,,, i'm sure on page 10, someone will yet again ask the same question.
no matter how intuitive u make a forum, ppl just dont want to put in an effort to even search their problem - drives me mad
