Locking Bootloader

---

Quick question, since I'm new to the Galaxy Nexus community.
I have unlocked my bootloader, installed CWM permanently, rooted and installed CM9 RC.
My question now is, if I was to lock my bootloader now, what exactly would happen? Does all hell break lose? Does CWM get deleted or remains in memory but cannot be accessed? Do I lose root (unlikely, but hey, have to ask).
Thanks in advanced,
Aphis

Nope nothing happens. Your phone will still work. Root will still be there. CWM will still be there.

Unfortunately, if you need to unlock your bootloader again for anything, you'll likely lose all your data since unlocking wipes most phones.

Check out the app "BootUnlocker for Galaxy Nexus" by Segv's Tools on the Play Store (play.google.com/store/apps/details?id=net.segv11.bootunlocker). You can lock and unlock your bootloader without losing data. It works on the phone itself, no computer needed.

I installed it on my phone a couple days ago and it works just as advertised. Still have root and CWM, all data still there, no problems.

Just a point to note: that app requires root. So if you lock your bootloader, and subsequently lose root accidentally, you will have to unlock using fastboot, which will wipe.

True, but when I did my initial root attempt on my phone, I unlocked the bootloader and my data was intact. I was prepared for a full wipe but it didn't happen. I do have root and I relocked the bootloader. I can't explain how or why it didn't wipe.

That because you have a Play Store Galaxy Nexus. Those do not wipe when you unlock the bootloader. We are trying to figure out why, but not quite there yet. See here.

Could anybody explain why would someone want to lock the bootloader back?

People that are extremely worried about their personal data getting into the wrong hands. If your bootloader is locked AND you have the stock recovery installed AND you have USB debugging disabled in settings AND you have a lock screen password, there is no way for someone to get your data off your device without some sort of hardware hack.

So, data security is the only advantage of locking the bootloader?

Yes, the ONLY advantage.
