hi bro, im planning to unblock the bootloader. i miss the smoothness of aosp

already backed up my TA
any other precaution?
1. backup TA
2. backup your data (images, videos, whatsapp, other important stuff)
3. backup your SMS
A. flash a 4.3.1 rom first -> download pacman rom (http://pacman.basketbuild.com/index.php?dir=main/yuga/nightly/) - download the latest nightly can already..
B. gApps (optional, but if you'd like. PA's gApps can already)
(not sure why but if you directly flash 4.4.2 from stock, it will not boot due to the system partition still having stock rom, but apparently pac-man is able to overwrite them to AOSP-based, so you can flash 4.4.2 after that)
------------------------------------------------------
i would say just go with CM11 4.4.2 12/15, at least i can restore without any problems (default sms to hangouts)
then you can install xposed and have all the other AOSP features
you know how to do all the rest? unlock bootloader, etc via flashtool?
also rmb, have custom recovery + root WORKING FIRST on your stock rom. (that way you no need to go through the trouble of flashing boot.img through fastboot in ADB shell mode)
just unlock BL -> flash custom AOSP zip
------------------------------------------------------
and make sure you flash everything correctly (lol, got 1 user in xda accidentally flashed samsung rom on his Z, phone permanently gone liao)
(sorry if its scrambled.. just stating out all the important stuff)
