When it comes to multi-device releases, it doesn’t get much more straightforward than a widespread Sony Xperia release. Given how close the hardware and software is between devices, it isn’t overly difficult to get a single piece of software working on a number of devices. As such, unofficial AOKP Jelly Bean was ported to 14 Sony Xperia devices practically all at once.
XDA Recognized Contributor championswimmer, on behalf of the KangXperiaProject, brings us the ROMs. However, many thanks go to the FreeXperia Team, whose work was critical to the achievement. In championswimmer’s words:
It is very important to mention here that nothing, yes i repeat NOTHING was possible without the awesome work done by FreeXperia team for the community. For all 2011 devices we are using their device trees almost untouched. So all the hardware work (making camera, sensors, gralloc, hardware acceleration etc work flawlessly) is purely the credit of FreeXperiaTeam (FXP, bin4ry, defer and Kali- ) If there is anyone whom you really need to thank for Xperia devices being able to run CM9/AOSP/AOKP/MIUI or whatever non-stock ROMs it’s the great people like : ZdZihu, FXP, Bin4ry, defer, Kali-, KeiranFTW, DoomLord, Androxyde, Achotjan, Azuzu and many many more. The only thing that KXP team has done is made the devices and vendor trees fit into the groove of AOKP source tree and manage a buildable environment. Our contribution in KXP ROMs is much much less as compared to the contribution of Team Kang and Team FreeXperia. (Ofcourse on older devices we had to work a lot becuase FXP does not support them anymore)
The functionality varies depending on device. However, there aren’t more than two or three things broken per device, and none of it is bad enough to be considered unstable. In addition to releasing the ROMs for all these devices, KXP has also written up a nice tutorial showing users how to download and compile their own source code. So if users want to grab the latest and greatest or just tinker around, it is available. Do be advised, the tutorial for compiling is for 64-bit Ubuntu, and will require at least 10GB of disk space.
