1:Get code from Sony
2:Unlock bootloader
3:Install Flashtool and root via towelroot (the order here is not important?)
4:Back up files
5:Install 4.4.4 via OTA
Done?
And then I'm left to be able to move back and/or install older firmware?
If this is a PITA to answer, I understand - appreciate any help

Be AWARE !
Before unlocking bootloader BE SURE TO BACK UP YOUR TA PARTITION OR YOU WILL LOOSE DRM LICENCE KEYS FOREVER !!!

Google "Sony DRM TA backup" to find more information.

OK.
I won't be 'developing' anytime soon, so no need to unlock. I just thought in order to access anything newer than 4.4.2 OTA from Sony would require it.
Thank you both and sorry again for the ?'s, but this has been WAY more involved than the days of rooting my Photon
Will continue my research on OTA 4.4.4.[COLOR="Silver"]

OK,
No 4.4.4 for SGP312 yet so I guess just be patient and make sure I'm rooted and backed up?
Any link for optimizing in the meantime still appreciated - many searches and I can't find anything.

OK
I was aware of 4.4.4 via FT and PC, but based on a post I had read in another thread, thought only OTA would allow one to maintain root after 4.4.2...
I should have read further into that thread.
This should do it -Thanks again Rootk1t
