You cannot go from a deodexed to odexed. You will have to do what the above post says and flash a new FW with either pccompanion or flashtool

You're in the wrong forum. There is a Xperia SP forum, search for it and ask there.
Generally download Flashtool and a .ftf file of a stock rom and flash it via flashtool

[Q] Help in downgrading Xperia SP

my friend updated the Xperia Sp to 4.3 and now it is very laggy. He need to downgrade to 4.1.2. I need the ftf file link for downloading and flashtool link as my old flashtool dont have xperia sp driver.
As this phone is bought from customs I am not sure to which region it belongs. Do I need to exclude baseband when flashing? Do I need to skip final verification?.
The baseband version of 4.3 update is 8960-AAAAATAZQ-40031007-18
See my tutorial in General section or via the link below in my signature.. All you need is explained in the tutorial
Good luck

How flash FTF ?

Hello! I was searching and reading several forums and threads and could not reach any conclusion. Therefore, I decided to create a new thread.
Let me explain: My old device was a Xperia Z2 (D6503) and now decided to renew... and I bought the beautiful Z3 Plus (E6553). The ROM that comes operator brings many junk files... and I want to install a Clean ROM. (Customized RU I have downloaded). But between my readed information, some versions of Flashtool were not compatible with our phone... I and downloaded the latest Flashtool version. But there are new options when flashing the FTF.
Could you please help to know what should I do? I do not want bricked my Z3+ please!
Thanks in advance :C
