Hello, I have flashed the new 10.1 fxp222 on my xperia z, and not totally pleasing me, I would go back to stock. I had also saved the partition TA, but I can not restore it, and we stock ftf to flash the software. Am I missing some step? there is a boot.img file to restore the stock? I have also tried to flash from cwm version stock + root of 253, but will not start
