bootloader-maguro-primekl01

If anybody's interested here's the PRIMEKL01 bootloader, latest version.

It's the same LTE/CDMA leaked version that's floating around, nothing changed as both devices share the same bootloader, as far as I can tell.

It's recommended by Google for those who are on 4.0.3 roms with same XXKK06 radio. I've flashed it running Mike's ARHD 2.1.2 and even though it's not a 4.0.3 rom it's working perfectly.

Inside the zip I've included fastboot for Windows for easy flashing.

Put your phone into fastboot mode and execute the fastboot-windows.bat file.

If you have any problems with it just flash back to the previous version.

Any actual improvement? Just wondering why its worth flashing....boot loader isn't something I have knowingly flashed before so can't understand what it controls that would yield a noticeable benifit. Any help clarifying this would be appreciated! Thanks

Wait so this bootloader is for LTE/CDMA devices then?

As stated in the OP both versions use same boot loader and I just used it on my GSM gnex and all is good and working.

Thanks gingernut for making this nice and noob friendly, hope you can keep this thread updated with all latest boot loaders as and when they come out with a 1 click flash like yours :cool:

So is there any word on what bootloader is recommended for UGKL1 radios ?

Should be all good as GSM and LTE use same boot loader, this being most recent and UGKL1 is a new(ish) radio.

I'm on XXKK06 radio (UK gsm) with Android revolution 2.1.3 with james bond 1.35 ghz kernal and all good here.

Would someone mind giving a little more detailed instruction on how to do this? Sorry, but I'm just not that familiar with fastboot. Besides, I'm sure I'm asking something a lot of folks are afraid to ask.

It's very easy.

1. Put the phone in fastboot mode: pull battery, then reinsert it and press vol up+vol down+power. The phone will boot with a green Android and some white text in the lower left. This is fastboot.

2. Plug in your phone to the PC, and install fastboot drivers if necessary.

3. Run the .bat file in the zip in the OP.

What's the advantage in this bootloader
Compared to others ? Anyone notice any improvements?

I can't say I have really noticed any differences really, the biotloader runs deep deep with in the the phone so at OS level you won't really notice anything.

The main reason for updating it is because its recommended by Google to use with these newer radios

I'm not going to say that you are making things up, but I would like to see this claim quoted before I take anyone's word for it. Sorry for being a sceptic, but bootloader and radio are two such orthogonally separated concepts that I just don't see the link.

If I am proven wrong (and that does happen :) ), I'll make up for being an asshole by adding a link to this thread in my radio collection thread :p

Please post checksums with images as critical as bootloaders.

I think he was looking for evidence that they are linked somehow? Just best they are recomended for the same android version doesnt mean they are intrinsicly linked.

Hmmm so know one knows why they are flashing this thing? Just need to get your RDA of 'flash' I think lol

The way I read this is that for a specific version/build of Android a specific bootloader is recommended. That I can totally relate to.

I can also see how a specific radio might be "recommended" for a specific Android-build, as that build might rely on or exploit specific radio-implementation details or optimizations.

What I don't see is any link between how flashing a radio leads to a "recommended bootloader". Sorry for being difficult, but I just don't see it.

I'll consider this flashing OCD until proven otherwise :p

No I agree, I've never known a specific bootloader to be a requirement for a Radio. Usually it's always the ROM itself requiring different versions due to RIL's and whatever else lies within, hence it usually always relates to the build version instead. :)

    The point is, unlike a newer ROMs or radios, which typically have improvements, newer bootloaders typically have added restrictions. This was the case in the Nexus One days, but eventually HTC forced everyone onto the later bootloader by making it a requirement to run stock Gingerbread.

    All nexus devices will not be locked with encrypted bootloaders. Shouldn't ever have to worry about a updated bootloader on Nexus devices that prevent fastboot oem unlock.

    Anyway to flash this using CWM?
