    Droid 4 Bootloader

    When the HTC G2 was released it to had a locked boot loader and the community decided to create a purse that everyone contributed to, too give devs some incentive to unlock the device. I believe it got up to about $1200 and it was successfully rooted and unlocked for cwm.


    think that will get the droid 4's bootloader opened up so we can get full control of this phone?

    Probably not, only Motorola can unlock the bootloader and that's if Verizon will let them. At this point in time Verizon won't care (maybe they will, probably) but I doubt Motorola is going to spend the time to unlock a device that isn't one of its newest.

    there has to be a work around to mod the bootloader.

    The kexec workaround is a kernel bypass that allows for custom kernels (I'm not sure to what degree)

    But this is the reality in the land of Motorola. Locked bootloaders, locked bootloaders everywhere...

    Motorola has to provide the keys to unlock the bootloader, it is so well encrypted that no one prepared to take on the unencryption process.

    The workaround uses a process called 2nd-init which kexec, if I'm not mistaken, is based off of.

    Basically it allows all of Motorola to load, the injects its own code, kills all of Motorola and then loads its own code, in this case, being a custom /system/ image as well as a custom /boot/ image of which the kernel is contained.

    There's a lot to it, and its a lot more complicated than what I just described above, but thats the watered down version.

    More on 2nd-init here: Still Loading ... blog:2011-06-14:2nd-init._what_it_is_and_how_it_works
    Kexec here: kexec - Wikipedia, the free encyclopedia

    Aside from the kexec hack, let's get back to hacking the bootloader. Would money help? It's becoming clear that there won't be another usable QWERTY phone for a while (ever?) and so we will stick to our Droid 4 until it falls apart. I am considering buying a second one, in fact.

    Re: Droid 4 Bootloader

    It's pretty much a lost cause. There have been several moto phones with bigger dev communities that have failed at cracking to bootloader. Just about everything has been done without the aid of Motorola.

    Money won't help, you'd need someone with an extreme know-how and passion to do it, and even then, the community has moved to newer and shinier devices.

    So, how do reach Motorola then? It's not like Verizon cares much about a year old phone, I guess.

    There was a petition to get Motorola to unlock the bootloader, but that's now closed with over 16,000 signatures. People have tried reaching out to MotoDev and Verizon, even going as far as to file FCC complaints against Verizon because of some clause they signed into when they acquired their LTE radio spectrum.

    Motorola finally changed its policy on unlocking bootloaders, but this mainly only applies to non-Verizon devices. The only Verizon devices that can be unlocked are Dev editions. Moto tweeted they have no intention of unlocking previous devices.
