I have gone ahead and tried this, done some testing. So far, I'm making progress!
I have gotten the European R800i ROM on my R800x Xperia Play.
It boots up just fine (new boot animation).
However, I am stuck at one spot. I cannot do anything except bring down the notification bar, view the Xperia Play games when I slide out the gamepad (VCast is gone!), and change USB options when plugged into the computer.
Here are the steps that I have taken:
-Full stock restore with FlashTool
-Flashed doomlords boot.img with the command "fastboot flash boot boot.img"
-Flashed frasertag's system.img with the command "fastboot flash system system.img"
-Flashed the system.sin from the R800i Firmware (I extracted it) with the command "fastboot flash system system.sin"
-Disconnected USB then turned the phone on. It boots just fine.
Now the reason that nothing actually functions at this point is because I only flashed the system.sin
from the R800i firmware (this is just a theory!). Trying to flash the whole ROM in FlashTool will result in an error and fail. I have read in another post that a trick to bring full functionality (besides the network) is to create a Nandroid backup before flashing all of this, delete the system.img from the backup, then restore the Nandroid backup after all of the flashing is done. The restoration part has got me stumped so far..
I will keep trying, and will ask the guy who I got this idea from how he got past the restoring backup stage (where I'm stuck).
I am determined to make this work! haha
