Custom Kernels for the Honor 8 and Honor 8 Pro Are Now Available

The Honor 8 was one of the best choices for a high-end, budget flagship last year, and the Honor 8 Pro is its recently released successor that brings a fresh design, amped up specs, and a bit more. Honor's EMUI interface has gotten quite a bit better over the years, but it still leaves that...

Kernel Sources Released for the Huawei Mate 9 and Huawei P10

Under the GNU General Public License (GPL), any modifications made to the Linux kernel must be publicly shared if users have access to the binary. Android itself is licensed under the Apache Software License which doesn't require modifications of AOSP to be open sourced. But because the underlying kernel in Android is Linux-based, all OEMs...

ElementalX Kernel for Moto Z And Moto G5 Plus!

Stock kernels simply do not provide the advanced features that we love. Smartphone vendors pack stable but bare solutions that give little room for customization and general improvement. Luckily, XDA is a place where a lot of kernel developers share their work. One of them, XDA Recognized Developer flar2, has just published his ElementalX Kernel for the Moto...

Unaltered, Prebuilt GCC and Linaro Toolchains to build your Custom ROM/Kernel

Basically, a toolchain is a bunch of development tools used in a chain (the output of one tool feeds into the input for the next tool, hence a toolchain), usually in order to compile source code (such as ROMs or kernels). Developers often use modified toolchains that can include optimizations for specific architectures focusing on performance...

OnePlus 3/3T Smoothness Increases with ‘Conservative’ Governor… Seriously (OxygenOS)

A couple of days ago,  u/AmirZ shocked the OnePlus subreddit when he found that setting the OnePlus 3T's "Big Core" cluster to a "conservative" governor would dramatically increase fluidity. Yeah, seriously. For those who haven't caught the contradiction here, the kernel's governor is responsible for managing the processor's scaling behavior, and "conservative" governors bias the phone towards their lowest...

Google’s Project Zero Discovered how to Bypass Samsung’s Knox Hypervisor (Fixed in January Patch)

Google's Project Zero team has verified a number of exploits that enable Samsung's phones running the supposedly-secure Samsung Knox security suite to be attacked. The blog notes that all vulnerabilities have been passed to Samsung who has actually released fixes for them in a January software update.

Diving into SDCardFS: How Google’s FUSE Replacement Will Reduce I/O Overhead

Several months ago, Google added something called “SDCardFS” to the official AOSP branches for the Linux kernel. At the time, the move was noticed only by some kernel developers, but otherwise flew under the radar of most users. No surprise there considering the fact that most users, including myself, do not really know what goes...

Xiaomi Releases Kernel Sources for Redmi 3S/Prime/X

Xiaomi, an OEM not exactly revered for their GPL compliance, has now released the kernel sources for the Redmi 3S, Prime and X on GitHub. The company has been known in the past for being lax when it comes to the timely release of source code under GPLv2, which is a common occurrence among various OEMs. While releasing the kernel source...

LeEco Releases Kernel Source Code for their Devices

The company launched the LeEco Le S3 and the LeEco Le Pro 3, and despite mixed reviews decrying the software experience, few have denied that these smartphones pack quite a punch in spite of their pricing. But software is something that can be fixed with enough tinkering, as we here at XDA are especially wont...

9 Year Old Linux Kernel bug dubbed ‘Dirty Cow’ can Root every version of Android

Despite the fact that tens of thousands of users actively pore over the Linux kernel source code actively looking for security flaws, it's not unheard of for serious bugs to go unnoticed. After all, though the chances of missing something incredibly serious are lowered by having more eyes auditing the code, we're all still human...

Android Nougat makes its way to the Nexus 5 & Nexus 7 (2013) via First Unofficial Port

Update 11:28PM CST: XDA Recognized Contributor zaclimon has posted the first unofficial port of Android Nougat for the Nexus 7 (2013) over on our forums. We've been expecting this to eventually happen after the initial release of Android Nougat, but perhaps not as quickly as we initially expected. Merely a single day after the release of Android Nougat's source...

Android Nougat Source Code is Dropping, Work on CyanogenMod 14 is Already Underway

Rejoice, fellow flashaholics! If you, like me, have been waiting for custom ROMs to pop up on our forums before hopping on the Nougat hype train, then your long wait will soon come to an end. With the official release of Android 7.0 Nougat the other day, Google has begun uploading the source code for the latest...
