Kernel Lighter Loads Kernels on Tegra 3 One X Away from PC

Up until recently, loading kernels onto the Tegra 3-powered HTC One X has been a relatively difficult affair. This was due to the fact that unlike its Qualcomm Snapdragon-powered cousin (originally called the HTC One XL), the Tegra 3 variant has not received S-Off. While not everyone would be bothered by needing to be stationed at a traditional computer in order to proceed with kernel flashing via fastboot, it can’t hurt to have these restrictions lifted.

In order to get around the issue, XDA Recognized Developer Thunder07 first looked to kexec. The name should sound familiar, as it has been used countless times to bypass various security measures or add additional functionality to unlocked devices. However, this came with some problems, as managing online hardware proved a tad problematic. Thunder07, however, came up with another way. Named kexec-hardboot, it works by, “loading the kernel into memory and force restarting the phone with new kernel.” In other words, it’s quite similar to standard kexec, but with the addition of a forced hardware restart.

Installation is simple. First you install a controller APK. Next, you use fastboot (and a connected PC) to flash a provided boot image. Finally, you flash another provided file through recovery, and you should be good to go. Instructions are provided in the thread for loading alternate kernels, and they are similarly straightforward.

It is important to keep in mind that with any major modification such as this, there is always the possibility that something can go terribly wrong, so read the directions carefully several times, and make sure you are willing to deal with the consequences if the flash doesn’t go as planned. If you’ve pined over the idea of loading aftermarket kernels away from your PC, head over to the original thread to get started.

Samsung Galaxy S6 Edge Drop Test

The Samsung Galaxy S6 and Galaxy S6 Edge are already proving to be amongst the head turners of 2015. From favoring their inhouse Exynos 7 SoC over the Snapdragon 810 SoC (which ended up causing issues to its main rival); to ditching the removable battery and micro sd card slot in favor of a more "premium" device, the flagship duo have a lot going on for them at this stage. Regarding the premium redesign which replaced plastic with metal and glass,...
