EDIT: OK, finally had the chance to update this.

Similar to what josteink has done with the radios here, I've decided to try and compile a list of all the available bootloaders for the Galaxy Nexus, so that people have a "one-stop" for all of them.

Unless stated otherwise, I've pulled all of these myself from either the yakju/mysid factory images from Google's site here or from the OTA update file list that I have compiled here.

If I am missing any, please let me know, or point me in the right direction.

Notes:
1) I have no idea what the differences are between the versions.
2) The maguro, toro and toroplus bootloaders are identical, so you can use them on all three devices.
3) The bootloaders are shipping bootloaders. To date, I have only seen two individuals report that they had engineering devices, and they have not dumped their bootloaders for us.

Disclaimer: I take no responsibility if you mess up your device by flashing any of these bootloaders.

I have attached both the fastboot image (extract from zip) and the CWM-flashable version.

Bootloader List (in order -- newest on top):
  • PRIMEMD04 - Source: takju JWR66V factory image. Posted by Carlos_Manuel here.
  • PRIMELC03 - Source: takju JRN84D update
  • PRIMELC02 - Source: mysidpr FD01 image. I found this in a post by Whosdaman here.
  • PRIMELA03 - Source: yakju IMM76D, yakju/takju IMM76I, and mysid IMM76K factory images
  • PRIMEKL01 - Source: IML74K leak. I found this in a post by Gingernut78 here.
  • PRIMEKK15 - Source: yakju/mysid ICL53F factory images
  • PRIMEKK14 - Source: theSpam posted it here. Shipped with original yakjuux ITL41D build - no fastboot-flashable image available at this point
  • PRIMEKJ10 - Source: yakju/mysid ITL41D and ITL41F factory images

Flashing bootloaders in cwm is just asking for a brick.
Let me guess: you are coming to the Galaxy Nexus from an HTC device, correct?

I can tell based on your post. :) HTC devices are notorious for brick with a failed bootloader or radio flash. There was no way to re-flash the bootloader given that we only had fastboot to flash it. Samsung devices are a little different: they have download mode, which can effectively flash images without needing to use the fastboot (i.e., bootloader) interface.

By the way, how do you think OTA updates flash bootloaders? In recovery...

+1 upon flashing the OTA, it does update the bootloader of their phone. It is perfectly safe, just be assured that the MD5 matches as the one in the OP post before flashing it in recovery / fastboot.

Tried downloading these, but evidently XDA is messed up right now and DLing any attachments results in a 554 byte file which is useless.

Good thing I check MD5-sums before flashing bootloaders :D

(PS: you spelled my name wrong in OP ;) )

Hmmm. It seems I can't download them either. I'll try re-uploading them later tonight -- I don't have them on my computer at work. HAve no idea what the issue is, as they seem to upload just fine...

P.S. Sorry about the name. Fixed! :)

    Jelly Bean 4.3 boot loader primemd04 (from Takju factory image)
    (Flashable through CWM):
    https://docs.google.com/file/d/0BxlYDVLp_RkMazBKUHU0ejVqS2M/edit

    Tested and working!
    Thanks to efrant for the script file.

    If you are going to flash that bootloader, then flash it at your own risk!

    I just found another difference between bootloaders when testing to make sure my GN BootUnlocker flashable zip works with every version (it does! ;)). Anything after KK15 has a green/yellow tint on my screen for the initial bootlogo, fastboot and recovery. KK15 and before have nice whites and crisp blacks. Any known bugs with KK15?

    Edit: Maybe this is part of the reason why yakjuux never moved forward from KK15. I think I'll stick with it for now unless someone recalls some bugs that were fixed in the newer versions.

    A bit late but I can confirm this works on toroplus :)

    will flashing a new bootloader format the memory and erase all contents?

    Nope only unlocking it will
