The Samsung Galaxy S4 built with Qualcomm’s Snapdragon has found its root exploit. This version of Galaxy S4 is released in the United States of America, Europe and other countries worldwide that supports LTE network capabilities as opposed to the other international Galaxy S4 that is built with Exynos processors. This root exploit has been published for Motorola devices only but it was found out that also works for the Samsung Galaxy S4, as the developers says. But there are some extra precautions that owners to learn about, since there are no custom recoveries or stock images available for now. If possible bricks could happen, then it is impossible to fix it until those needed files comes around.
The root exploit developer emphasized that this will only work on Qualcomm-based Galaxy S4, including the AT&T, Sprint, and T-Mobile branded models. Just take note other variants may possess a locked bootloader, preventing the installation of unofficial ROMS or recovery systems. Just ask the developer for any answers you might need to know.
Here’s all Samsung Galaxy S4 with Qualcomm Snapdragon variants:
GT-i9505 international LTE
SCH-R970 Cricket, MetroPCS, US cellular
Again, rooting voids the warranty of your handsets and if you’ll break it you’ll need to pay the costs of any damaged you’ve done.
