FIRST STEP: Prepare your environment I do this in a ubuntu 16.04 64 bits
1.- Install java:
2.- Install the necessary tools to make an Android build
3.- Get repo and configure it
3.a- Open the bashrc file included in the repo tool:
3.b- To set the right path for your local bin folder, paste the following code to a new line at the very bottom of the bashrc file, and then save the file using Ctrl+X:
4.- Reload bash variables to include the new path:
SECOND STEP: Initialise the AOSP tree
1. In a terminal window, enter the following commands:
2. Create and open a file where you will later add Sony’s repos containing the device configurations for Xperia devices, by entering the following commands:
3. Add repos for our seagull by copying and pasting the following text into the file, and then save the file using Ctrl+X:
4. To download the code into the device repos created above, run the command
THIRD STEP: Add necessary patches from the AOSP upstream branch
In order for certain functions to work on the hardware in Xperia devices, you need to add a set of patches from the AOSP master branch. This is done by executing the following commands:
In a terminal window, enter:
FOURTH STEP: Building our own upgrade kernel
1.- I prefer build the kernel on a different directory that the android sources so we go to create the directory tree and get the toolchain
1. Export the cross compiler&update bc (I need it)
2. Download the kernel source from GitHub
3. Configure the kernel: Configure the kernel is a required step before building it. Kernel drivers can be turned on or off, or be built as modules. This has to be configured in order for the kernel to function as desired. Configure the kernel by entering:
4. Build the kernel and needed modules: When building the kernel a compressed kernel image file is created and placed in the default target arch/arm/boot/zImage on your computer. To start the build, enter:
5. Now we have our vzimage we need to rename it and copy him to our android tree
FIFTH STEP: Building our ROM
1. Enter the following commands:
2. When prompted, pick the number corresponding to your device in the list displayed and press enter.
3. To start the build, type:
This step will take a long time. It may take up to several hours, so go grab a coffee or play a game while you wait. When it’s done, AOSP images that can be flashed to a device will be ready.
Flash AOSP image to your device
Before you flash the images that you built in the previous step, you must make sure your device is unlocked through Sony’s unlock boot loader service. Then you can flash the AOSP images on your device by following these steps:
1. On your device: Connect the device to your computer in Fastboot mode, by pressing volume up while inserting the USB cable. When the device is in Fastboot mode, the LED on the device will be illuminated in blue.
2. On your computer: Flash the boot, system and userdata images by entering the following commands in a terminal window:
PROBLEMS FOUND
1.- while compiling the driver i have found just one problem, the file "bs_log.h" wasnt found so you can do this
and paste this
2.- while compiling the entire rom i have a problem with "unsupported reloc 42" the fix is the next
look for this
and change for this
BUGS FOUND
unknown baseband so the device dont connect to the network from operator, i'm looking info and help to fix this.
1.- Install java:
Code:
sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install openjdk-7-jdk
Code:
sudo apt-get install bison g++-multilib git gperf libxml2-utils make zlib1g-dev:i386 zip
Code:
mkdir ~/bin
curl commondatastorage . googleapis .com/git-repo-downloads/repo> ~/bin/repo
chmod a+x ~/bin/repo
Code:
sudo nano ~/.bashrc
Code:
export PATH=~/bin:$PATH
Code:
source ~/.bashrcSECOND STEP: Initialise the AOSP tree
1. In a terminal window, enter the following commands:
Code:
mkdir ~/android
cd ~/android
repo init -u android. googlesource.com/platform/manifest -b android-6.0.1_r46
