Motorola RAZR GSM Bootloader Bypass Discovered, Could Work on LTE RAZR

In the never ending battle with bootloaders of Motorola devices, developer kholk thinks he may have found a way to bypass that of the GSM RAZR and maybe even the LTE DROID RAZR here in the States. He is said to be using the kexec method that was last used on the original DROID X, but so far other details have not been made public. Over the last couple of weeks, he has popped into this XDA thread to give a status report on his findings. As of Sunday, he seems convinced that his method works on the GSM and LTE RAZRs, but so far, only 1-core of the dual-core OMAP4430 is functioning. Once he can get the 2nd core fired up, he plans to make everything public.

From my understanding of kexec, this method won’t unlock the bootloader of the device, but it will allow you to flash a custom kernel. This would be a major happening in the land of the RAZR should kholk succeed. I wouldn’t recommend holding your breath on this one as someone seems to get “close” with each new Motorola release and then eventually gives up. Feel free to cross a couple of toes though.

Cheers Trevor!

    It would be cool if this could be worked to find a home on the Bionic, Droid 3/4, etc.. 

    I’d finally break down and buy the accessories for my Bionic and call it a day.

    Hi all, I’m kholk! :)

    I wanted to say to Kellex, the author of this post, that he’ve written something wrong!
    He gave credits only to me and that’s not right.

    I’m working on this with [mbm] and I’d be grateful to Kellex if he modifies the news including [mbm]‘s nickname.

    Thank you!

      My thoughts exactly as I read the post. I know [mbm] has been working on this a while. I applaud you for coming forward to give credit where it’s due.

    I hope it works. Every little bit helps.

       sounds painful …. :-/

  • wat?

    It will allow you to flash a custom KERNEL with a locked bootloader? Are you sure you don’t just mean a partial custom ROM like on all the other phones with locked bootloaders?

    • http://www.droid-life.com Kellex B

      No, normal phones with locked bootloaders can’t flash custom kernels.

    • Droidzilla

      There are already ROMs without custom kernels for the Droid RAZR (including ICS).

      Kexec, as far as my limited knowledge goes, places a new kernel on top of the original kernel after boot, effectively erasing/replacing the old one with the new one. Of course, this is not the most ideal for us, because this would have to occur at every boot, and might take a little bit longer than usual, but it’s the best chance we have.

      Ha!

  • Blackbullet4749

    Wonder if we could use this on the bionic too?

    • KnightCrusader

      Or the Droid 4.

      • Guest

        Or the Droid X Slider 4G LTE Bionic Pro

    Wowwwwww

    If this works…i might consider trading my Gnex for a Maxx. The difference in battery life would make the difference.

      so, does it work?

        orrrr until something better comes out

  • CurrentWeb

    I remember us trying this same method with the Droid X/2. Kexec is a great little proof of concept, but making it work requires rewriting entire drivers for the phone. That’s were the Droid X kexec project stopped, someone would have to devote so much effort into it to make it even basically function.
    I really hope this guy is just amazing and has everything sorted out, but I’m extremely skeptical…

    • Natty Bee

      yeah, I seriously doubt he’s going to get it going…we’ll see though, I hear he got a razr donated to him from Droidrzr.com  ;-)

  • Michael Forte

    This reminds me of that time where someone said they had the unlock code for the Droid X and instead was just trolling everyone…

      That feels like an eternity ago. I remember how pissed i was

      • http://www.droid-life.com Kellex B

        Hah yeah. The best part was he even had devs believing it was real.
