Hi everyone.. Im back on Xda after a long time.. So i bought a 2013 Moto X Att XT1058 with an unlocked BL and i got so lucky! It already had an unlocked bootloader! So voila.. Now my question is that i am on Stock Jelly beans which is 4.2.2 and i haven't rooted yet so the thing is that i love the camera patch on 4.4.2 that motorola did! and i also want to flash a custom rom. So i was thinking to take the 4.4.2 OTA and then start the flashing game. Now i want 4.4.2 just for the camera patch and im not sure that if i flash a custom rom then the camera would look good . Now these are my questions please answer them in detail.
Question 1: Can i safely take the 4.4.2 OTA and still have an unlocked bootloader? my unlocked bootloader wont get in any kind of vulnerability? please clear this issue for me im really afraid of getting locked! like its a blessing on the att moto x that the bootloader is unlocked so i cant loose the BL unlock anyhow.

Question 2: If i install a custom rom on the Jb rom will i able to get the decent camera like in 4.4.2 from motorola? or will i have to take the Motorola ota to get the fancy camera? So is it necessary for me to take the OTA in order to get the fancy camera? or a custom rom will provide me the fancy camera in the 44.2? Notice: i matched the camera of a 4.2.2 moto x with a 4.4.2 moto x. And 4.4.2 killed the 4.2.2 Camera. So that's why i want the Camera like in 4.4.2. Please tell me what should i do.

I want these questions to be answered urgently so i can start my work i really need to do it fast.. Anyone's help will be really really appreciated!! Please help.
