No.

The reason is this: when you have a locked bootloader, the bootloader checks for signed boot images. If it doesn't detect a signed image, it'll flag a security error. Once the bootloader is unlocked, you can run whatever boot image you want (i.e. flash custom ROMs with custom boot images).

(Some) ROMs can bypass this if a developer is using 2nd-init or hijacking. A good example of this is the bootstrap recovery CWM that is available for L9s with locked BL. Some of the older custom ROMs for the L9 utilized hijacking because they hadn't figured out how to unlock the bootloader. Unfortunately, those ROMs are only for the P760, and are quite old.

On the plus side, since the source is out there, a developer could take the bootstrap code and apply it to a current build of CM10.x for the P769, and have a working build of CM10.x for use with locked BLs.

Yeah, man. I got the same phone (MetroPCS L9), and I got it to unlock on the first try. It's not difficult (the process is similar to rooting), but it'll take you about 1 hour or so to do it right.

Once you unlock, it's much better because you can run whatever you want... And you can switch out ROMs whenever you feel like it. :rock:

EDIT: Forgot to mention... Having root first is better because now you can install bootstrap CWM, make a backup of the stock ROM, and then unlock the bootloader. That's what I did.

Yeah i figure thats why i rooted first, ummm just watched the video, its actually very simple and not hard to follow. Like you said similar as rooting just a few added steps. will do in about an hour and a half... ill report how it went

Ok so i have followed this video: (Tutorial)How To Unlock BootLoader P769 - YouTube everything has gone fine, the only problem i just ran into is where he says to re install driver at Device Manager and instead of getting Android like him im getting three other things and not Android. Dont know what to do from here on, im trying to update those three things and windows update cant find updates to them.

So like hes say's im at fastboot screen on phone waiting to flash recovery and windows wont recognize the device yet.


ahhhhhhh nevermind lmao i just missed a word on one of the commands, turns out it is reading it


All Done
