Researcher Unlocks Galaxy S4 Bootloader For AT&T, Verizon Phones 75 75

Trailrunner7 writes "Those of you who like to tinker and jailbreak Android phones should take notice of some new research conducted on Samsung Galaxy S4 Android devices shipped by AT&T and Verizon. Both devicemakers ship the Galaxy S4 smartphones with a locked-down bootloader that prevents users from uploading custom kernels or from making modifications to software on the phone. Azimuth Security researcher Dan Rosenberg has found a vulnerability in the manner in which the devices do cryptographic checks of boot image signatures and was able to exploit the flaw and upload his own unsigned kernel to the device."
