[Q] Why bootloader can not be unlocked like Kindle ? - Motorola Droid RAZR

In razr there is OMAP 4430
in KINDLE there is OMAP 4430
http://omappedia.org/wiki/Bootloader_Project
Why not to use unlocked bootloader from kindle, u-boot.bin ?
http://omappedia.org/wiki/Bootloader_Project said:
SD Card Boot
In the case of loading the u-boot via the SD card, the SD card x-loader looks for a FAT32 partition on the first MMC controller and scans the top level directory for a file named "u-boot.bin". It then transfers the file into main memory and transfers control to it.

even if on razr it is encrypted, can we not delete it like this guy here ?

p/s : someday when I don't need this phone.. I'll kill it this way
If I'm lucky, I'll get to boot an unlocked bootloader.

Use the search engine and look for the thread where unlocking our bootloader is attempted, as long as I remember there was some kind of hardware issue against it and that the omap 4430 chipset in our razr is locked down to take only signed bootloader, which is heavily encrypted by moto.
Even the devs were surprised of what they found when they tore down the chipset (quite different even when compared to the XT910 development edition which comes with unlocked bootloader), whirleyes is very skilled and if he really thought that it worths the risk to try he would have already done, as he said is more possible to kill the phone that way than any other result.

Ok, i will search for this thread...but as you can see he obviously need his phone now, he said that he will do it when he will not need it....
And the person in thread i cited, this Portuguese guy, was able to delete all files, so PC seen his phone as pure OMAP 4430 chip...

Technical explanation here of the hardware-locked bootloader: http://forum.xda-developers.com/showpost.php?p=21280773&postcount=32
Sadly same chipset doesn´t always mean same hardware configuration.

Ok, but i still dont understand what locked bootloader have to do with loading custom complied omap loader, u-boot.bin ?
http://omappedia.org/wiki/Bootloader_Project
Even if there are some eFuses or reverse Efuses, one time programmable inside this chip, and even if this bootloader can not be decrypted and unlocked, is it possible to unbrick this phone in the way described here to repair phone bricked by this portugese guy ?
http://forum.xda-developers.com/showpost.php?p=34488311&postcount=10
If unlocking bootloader is not an option, is unbricking this phone an option ?

Motorola made fake advertisements and news on the net about the bootloader being unlockable where there're no operator obligations but they never offered bootloader unlocking option to any of us. I believe it is never too late, still expecting a bootloader unlock magic happening to this strong and classy device. It would be a killer with a longer life.

I have an unlocked bootloader therefore it can be done. It,s a dev edition and was bought at second hand, so no info about it...
