I have questions
My HTC One is on stock rom, but bootloader unlocked, and rooted.
Now, I want to upgrade to 4.2.2.
What is the correct steps to upgrade to 4.2.2. I would like to have root again on 4.2.2

Can I use OTA to upgrade?
After upgrade, I assumed that I will lose the root and CWM recovery,right?
But will the bootloader locked again?
My concern is, if bootloader is locked, I will need to unlock it and it will wipe all my data in sdcard.
