Root the Droid 4 Thanks to This Exploit by Dan Rosenberg

While all evidence that the 4th iteration of the original Droid pointed at a December release it was pushed back to February of 2012 and a lot of folks became a bit grumpy. Well it’s finally February, the Droid 4 has been officially announced and is upon us. Released yesterday it didn’t take long for the development community to root the device. Security Researcher Dan Rosenberg was able to get root only hours after the device went on sale. However, before he released the exploit he decided to try an experiment.

He would only release the exploit if a $500 bounty was met. This bounty though, wasn’t an attempt at holding a file hostage to make a quick buck but rather, for a good cause. He wanted the first $200 so that he could continue modding and developing support of the device. The other $300 would be donated to the American Red Cross.

Personally I feel that this is a noble idea. Seriously, everyone paying a few bucks to get this man a phone to continue custom development on a new device while also giving money to a charity in the process; it’s an honorable concept. Well apparently I am in the minority in this thinking as Mr. Rosenberg received a number of complaints in how this idea was unfair. Worry not, rather than abandon his work and not release the exploit Rosenberg took the high road. He has decided to release the exploit free of charge and any money donated for his hard work will be donated straight to the American Red Cross. 

Mr. Rosenberg turned a negative into a positive here, which is great to see. What’s not so great is the fact that people who take advantage of these mods and exploits expect them free of charge. The fact that we get upset because a dev is trying to do some good for both the Android community and Charity is ridiculous. We shouldn’t just expect developers to give us their hard work for free. It’s a privilege that they spend their free time making it possible for us to get a whole lot of extra milage out of our devices. Personally I don’t even own a Droid 4 and I am going to go donate to further support the community. We need to show our devs some love because without them then Android would just be another phone OS without any excitement. But I digress.

If you would like to thank Mr. Rosenberg for his hard work and dedication to the Android community then you can head on over here to donate to a good cause. For those that want to root their Droid 4 scroll down a bit further to download the file and find the instructions. As always rooting will probably void your warranty and any issues you have will be your sole responsibility. Also as of right now this exploit only works for Windows machines. You can even check out our CES hands on video or the Wirefly in-depth video review on the QWERTY phone. Enjoy!

    Hi Dan

    I keep getting Permission Denied when it is trying to copy files to data/local.

    I’m running ICS on Droid 4.

    I’m more than happy to cover the cost of any advice or donate to a charity of your choices – I’m in SA on business and while I can use my phone for calls, without rooting it, I cannot upgrade the radiocomm settings.

    Thanks
    Wayne

      Is there a solution to access denied on /data/local?
