This is my first tutorial so please tell me if I missed anything
This thread will teach some noobs here who are on stock 4.1.2/4.2.2 and want to flash latest roms like cm12/cm11/Euphoria Os and etc. This tutorial is self-tested by me!
__________________________________________________ ____________________________
1) Firstly, you should unlock the bootloader. To do this go to this thread> http://forum.xda-developers.com/xper...cking-t2332900 (after flashing you may get a bootloop so flash stock ftf to recover > http://forum.xda-developers.com/xper...cking-t2337955 http://forum.xda-developers.com/xper...ocked-t2560642
2)You should install a recovery > http://forum.xda-developers.com/xper...aller-t2589320 for this you need root > http://forum.xda-developers.com/xper...-root-t2591290 Backup your stock rom(optional) and TA(if the phone gets damaged during warranty) and copy rom zip file to sd card http://forum.xda-developers.com/xper...beta1-t2571273
3) In recovery Wipe cache/dalvic/art cache> Factory data reset> clean to install a new rom
4) Flash the rom and Gapps for specific rom(may not be included so google (the version of android gapps) and flash it after rom. Edit: Flashing kk is not necessary. ;)
5) Reboot and wait for some time... Instalation takes some time... :good:
__________________________________________________ _________________________
6)(BONUS) If you want a good recovery like philz/twrp > http://forum.xda-developers.com/xper...klick-t3068084 just install an app and click install philz. The app that installs a recovery is unique. It won't be overriden by another rom's recovery and u won't have to flash tz boot.img again and again... Thumbs up if you liked my tutorial :good: I do appreciate it! And of course, if you need any help just comment here or add me on facebook.
I'm here to help you guys!

Edit: There are so many good roms for our XL on xda( I don't compare hard work of devs). Here are some ones that I tried and suggest checking out:
Euphoria OS: http://forum.xda-developers.com/xper...s-1-0-t3069503
Ressurection remix: http://forum.xda-developers.com/xper...5-3-0-t3008255
Glade rom: http://forum.xda-developers.com/xper...e-rom-t3060544

Install the app and click philz if your bootloader is unlocked. BTW it's written in that thread that can only be installed on cm12/cm11 etc. But not on stock. If you want a recovery on stock rom try the step 2)

cm11 isnt nessasary...

cm11 overrides system and userdata partition...

cm12 does the same... so there isnt any differenz in flashing cm12 from stock or from cm11....

only thing usefull is to flash latest stock before flashing cm12 ... because other than custom roms ...stock rom will override nearly all partitions.... that means better modem...baseband ...etc... so you should come from last stock
