Description
This application REQUIRES a Galaxy Nexus (maguro, toro or toroplus), Nexus 4 (mako), Nexus 5 (hammerhead), Nexus 7 2013 (deb or flo), Nexus 10 (manta), OnePlus One (bacon / A0001), OnePlus 2 (OnePlus2), or OnePlus X (OnePlus / ONE / E1001), with root.

You've rooted your device, and you are trying to decide between the security of relocking your bootloader (with stock recovery and USB Debugging off), and the flexibility of leaving it unlocked.

You know that in order to prevent an unauthorized user from accessing your data by flashing a custom recovery, "fastboot oem unlock" wipes your data. This also means that if you relock your bootloader, you will need to do a full backup-and-restore whenever you decide to unlock it again.

BootUnlocker for Nexus Devices lets you have the best of both worlds by using root privileges to unlock your bootloader from within Android, without wiping your data. This allows you to keep your bootloader locked for security, with this application safely protected behind your lockscreen password. Whenever you want to unlock or relock your bootloader, just unlock your screen and run BootUnlocker.

I'm really glad you've brought this over to the Nexus 4. This is an excellent contribution to the community.

karanrajpal14 · Dec 25, 2012

I have a small doubt and i hope you don't mind clearing it. I just got my N4 and i was considering rooting it, my doubt is that once i unlock the boot loader can i relock it? On my old htc explorer it was possible to re lock but it showed the status as re locked instead of locked hence voiding the warranty. Can i relock it and get my warranty back again? Sorry for a probably noobish question.

It won't show as re locked. It'll be simply 'locked' whether you use the app or manually do it via terminal

Thanks. So it's safe to root it then? Won't cause any problems with my warranty right?

If it's a question on being safe, I'm pretty sure most people with sense will always say "do it at your own risk" because we are concerned about your warranty. Nexus devices are the easiest to bootloader unlocked and root and flash and viceversa but the user still has to take responsibility.

That's fine. I'll do it at my own risk! Only thing I was worried about was the warranty. Now that you say it can be locked again I don't have any problem! Thanks!

thanks for this. maybe put a a disclaimer like the one said in this link http://xdaforums.com/showthread.php?t=1898664

advantages:
- doesn't require encryption (for those who do not wish to use it).

Disadvantages:
- relies on third-party apps.
- method will not work if you lose root access for whatever reason.
- method will not work when you cannot boot into Android for whatever reason.

i am quite new to this area so my question is, once I have relocked the bootloader, does the stock recovery allows for nandroid backup etc? and since in the worst case scenario that i am not able to boot, i have no other alternative other than doing a fastboot oem unlock?

thanks for your time!

segv11 · Jan 10, 2013

The stock recovery does not do nandroid backups. You don't have to flash the stock recovery in order to lock the bootloader, but it is a good idea...

I've tested this app in my Nexus 4 and it works like a charm. Thank you very much!

Re: [APP][2012-12-24][root][N4] BootUnlocker for Nexus Devices -- version 1.3

I just want to confirm that this tool is working with the newest bootloader MAKOZ10o from the 4.2.2 OTA upgrade.

Sorry, not wanting to thread hi-jack here or anything, but this seems like the best place to mention it. If you've ever had the experience of rebooting to bootloader and you've forgetten to unlock in BootUnlocker first, or, you really screwed something up and can't boot the OS in the first place to unlock with the app, I made a recovery flashable zip that will do the same thing. Always handy to have on hand in case of emergencies.

Cheers! :good:

Edit: I see it answers all of @azrash's disadvantages list too.

VivaErBetis · Jul 18, 2013

Just a quick note to confirm that this fantastic tool works with the new nexus4 MAKOZ20i bootloader (android 4.3 JWR66N & JWR66V).

Yes. It works both ways, locks if unlocked, unlock if locked. Really great!
