How to Extract the Boot Image From Sony FTF Files

If you’ve been thinking of developing your first custom ROM for your Sony Xperia device, chances are that you probably need a kernel to go along with it, especially if the ROM is for devices with locked bootloaders. Because of this, it’s sometimes best to know how to extract the kernel from an FTF file in order to integrate it into your ROM.

A great place to begin with would be a tutorial by XDA Recognized Contributor matt4321 and XDA Recognized Contributor and Themer DaRk-L0rD. Divided into two parts, the tutorial first guides you through the steps of extracting a kernel from an FTF file and converting it into a boot.img file. The second part teaches you how to make a flashable ZIP package containing your freshly extracted boot.img file.

Additionally, because the kernel is located in different partitions in different Xperia devices, DaRk-L0rD also includes a handy list of just where you can find the kernel for your particular Xperia device. Just keep in mind, however, that not all Xperia devices are on the list at this time, so DaRk-L0rD also provides a simple way of finding out the directory yourself.

New AOSP Branch Details Potential Build System Upgrades?

While there are frequent unexplained changes and pushes to Google's AOSP repositories, an interesting-looking new branch has been pushed out recently, called "master-soong". Taking a look at the changes made to the manifest repository (which is used to specify the repositories to be downloaded when building Android), it appears there are some new repositories making an appearance. Of note here are new prebuilt repositories for Go, and Ninja. Go is a programming language, created by Google, which compiles to produce...

Send Links to Any Nearby Device with CaastMe

There already are many solutions on the Google Play store if you want to send a link to one of your devices -- but what if you wanted to do it quickly without having to install any software or logging in to a website on the recipient end? Most apps require you to do either or both, which can be a hassle (or even a security risk) in some cases. Luckily, XDA Forum Member wyemun has developed CaastMe. Inspired by...
