Tools - Unlock the bootloader

• The unlock service allow tech community to open up the device in a

controlled way

– DRM certificates => services that require certificates stop working – Userdata partition are wiped

• Only none-simlocked phones can be unlocked (investigating a secure

solution for simlocked phones) 1. Go to http://unlockbootloader.sonymobile.com ”Start Unlocking the bootloader” 2. Accept the legal terms pop up 3. Enter IMEI and your personal information to get key 4. Key is used in fastboot, to unlock phone

• Open for external collaboration

– What can you get out of it:

• More Open Source!!! 
• Latest Binaries

What do we actually provide?

• Kernel, as always (github)
• Device configuration (github)
• Proprietary binaries (developer.sonymobile.com)
• The source for Android itself is downloaded from Google.

PA1 2013-02-21 24 Confidential

Kernel

Based on the Qualcomm kernel with Sony adoptions The source code including details on how to build is available at: https://github.com/sonyxperiadev/kernel/wiki

PA1 2013-02-21 25 Confidential

Device configurations

Following the conventional AOSP style for device/sony/xyz. These are available as gits on github. There is one device/sony/lagan that is common for all variants of lagan devices, and one device specific git, e.g. device/sony/c6603. The device specific git actually covers variants of the same device. I.e. c6603 should work for all c660x devices.

PA1 2013-02-21 26 Confidential

Proprietary binaries

There are several parts of the device software that we cannot make available as source code. Some of these parts are however available as binaries for download at our developer site: http://developer.sonymobile.com/knowledge-base/open-source/android-

• pen-source-project-for-xperia-devices/

Intended usage

• Playing around with AOSP on Sony devices
• Development tool for people doing Android ROMs for Sony devices

=> This is not intended for consumer devices, or every day use.

PA1 2013-02-21 29 Confidential

Objective moving forward

Basically we want to support all versions of android on all Sony devices. This may not be possible, but we’ll try for some of them… We want to build as much as possible from source. We want to enable as much HW as possible.

PA1 2013-02-21 30 Confidential

Can people contribute?

Yes, please!

• AOSP changes every day, and every day something may break on our side.

Getting a heads up when that happens is greatly appreciated

• If we messed something up in the kernel or configuration we love to hear

about it

• Talk to us on github or developer.sonymobile.com
