Here is an image for what it is worth! Dan Rosenberg has really been on his game as of late. He recently Rooted JB on Moto Devices, unlocked the bootloader on the Razr HD series of devices, and now it appears that he has unlocked the bootloader on the Galaxy S4. The above photo is all that Dan has published so far. For now we are unsure if this is Verizon or AT&T variant of the S4. As far as I am aware there are not any Verizon models in the public, but we could only hope. Apparently this unlock comes with recovery as well. Sources have told me "The S4 is unlocked sorta", and "Dan will release details publicly later." This is huge news! Be sure to Follow @DjrBliss on Twitter as this is more than likely where you will find out the details. If he releases his method it will probably be released to vulnfactory.org Via @DjrBliss - For more discussions on Galaxy S4 Development visit: http://www.droidforums.net/forum/samsung-galaxy-s4-development/ [UPDATE]- Dan has posted some clarification on XDA here Here are the facts. -The Image is of an AT&T Galaxy S4 (which ships with the bootloader locked) -This will allow you to run custom Kernels and Recoveries -This won't be released until Late May when the Verizon Galaxy S4 is Released (for obvious resasons) -It is highly likely that this method will work with the Verizon model, but it is untested since Dan doesn't own one -This will release when it is released, pestering Dan won't make it happen sooner -This is not the result of a Leak -You can Donate To the cause here -You should avoid all OTA updates if you would like to use this method to unlock your bootloader -Lastly Dan's favorite color is blue That about wraps it up. Can't wait till my Verizon Galaxy S4 gets here!
