Question [Q] Trying a custom ROM for the first time from complete stock

Hi,

I'm looking to try some 4.4 custom ROMs on my GF's GSM Galaxy Nexus for the first time coming from stock.

Am I right that, I need to: 1) Unlock the bootloader and 2) Install a custom recovery before I can flash a ROM, right?
What would we be the easiest way to achieve both? I've read some stickied posts and I think using the Nexus toolkit is the easiest way. Someone please let me know if it isnt.

Also, I shouldn't worry about rooting the device for now, right?

One last question, I plan to factory reset the phone before installing the custom ROM. A NANDROID backup should allow me to easily revert back to the pristine stock if ever my GF doesnt like the custom ROM, right?

Hope someone can help clarify these things before I actually go on and try the whole thing.

Thanks.

You can use the toolkit but I would use command prompt / terminal for unlocking bootloader and flashing recovery.

1. When you unlock the bootloader all data from Nexus will be gone.
2. You need Nexus USB / Fastboot / ADB drivers:

3. You need fastboot files:

4. Command to unlock the boot loader:
fastboot oem unlock

5. Command to flash recovery:
fastboot flash recovery file-name.img
CWM recovery .img file: http://www.clockworkmod.com/rommanager

Thanks for the reply.
Will try the command prompt method.
After I unlock bootloader and flash CWM, i'm basically left with factory reset phone, right? Would be a great time to do a NANDROID backup then so I can revert to it in case I want to, right?

When you unlock your phone, it'' be automatically wiped... so you don't have to do any factory reset.
I don't know how do you make a nandroid backup when boot loader is locked and recovery is the stock one..

It is just one time wipe when unlocking bootloader. If you decide to revert to stock, you can flash factory image and start over.

Unlocked bootlader gives you ability to flash custom recovery which gives you nandroid backup.
