[Q] I'm confused about unlocking bootloader

[pepo36]

I bought the atrix 4G from Egypt so i guess its the international one
i already rooted it ....however i dont have a custom recovery installed

I wanted to unlock the bootloader but in the instructions it says i should have a backup first which means i need CWM installed first to make a nandroid backup
when i go to install CWM it says i have to unlock bootloader first

I'm confused about which step should be done first, unlocking bootloader or installing CWM?

Can someone please walk me through this?

Think about it for a secon. Even if there was a way to make a nandroid backup without a custom recovery (and there actually ARE ways to do it), how exactly would you perform a restore of that backup if something goes wrong with unlocking the BL and/or installing a custom recovery?

I read that you lose all your data and application if during unlocking the bootloader
i'm just assuming if it went well , i dont wanna set up everything from the beginning i just want to restore it

but yeah that's something to consider you r right, i still want to know which step to do first ?

You lose nothing by unlocking the bootloader. However the procedure for doing that might at one point make your phone unusable until you flash custom recovery and then some ROM (custom or stock or whatever). And that is where you're likely to lose data.

You don't need a nandroid backup to retain data though. Just back it up using TiBu.

but yeah that's something to consider you r right, i still want to know which step to do first ?

In a nutshell:

1. make any backups using TiBu
2. download a fruitcake firmware you want (probably the same version you have right now)
3. unlock the bootloader
4. flash custom recovery
5. flash the fruitcake
6. boot
7. restore TiBu backup
