Hi guys, I have the Xperia SP C5303 with an unlocked bootloader but the issue is I updated it and it's now running on Jellybean 4.3 Build number 12.1.A.1.201. I've done some research and got conflicting info as to whether I can root the phone and install Cyanogenmod. I'd really appreciate some help in this matter and especially if somebody can give me detailed instructions on how to root and install Cyanogenmod on this device if it's possible. Thanks in advance.
You need to flash the old 4.1.2 firmware first and carry out the root/recovery on that then do whatever you want after that.
People with unlocked BL may be able to tell you if theres a quicker way with flashtool to just flash a kernel with recovery but I dont know if thats the case.
