First flashing steps..specific questions inside. Need help. Thanks - Sony Xperia Z Ultra

Hello!
So here I go...first trying to root so I need to go back to 532 BUT I cant find one for the C6802 and USA. Even the one in the link that says TW is a dead link.
Wondering if flashing the [STOCK ROM] [FTF] Xperia Z Ultra (C6806) 14.1.B.1.532 "US Retail" is a bad idea.
I am sure I will have more Qs after this one but this one already got me stuck right off the bat :crying:

PS I found one for HK C6802_14.1.B.1.532_HK.ftf maybe that works?

Yo!
It doesn't really matter which version you pick. It'll work as usual. And yes, the HK version will work fine, but it might boot up with chinese language. I'm not really sure. Or you can flash the european version for the C6833.

---

Ok I also downloaded the C6806 US version but I can use that C6833 European version if you think is a better idea.
I think I can try what I have no harm done, then try another one if that one did not work fine. Right?

Yeah, whatever you feel like doing You're only downgrading to root, so after you've changed the CDA and gottten the OTA update, you'll end up with a german firmware (unless you find a different CDA that has OTA). Either way, just do whatever you want. If it doesn't boot or the ROM is wonky, it'll only take you a couple of mintues to flash a different ROM.

Ok so finally ready to try the firmware. I see stuff like Partition, TA etc on the flash tool. I dont see anything instructions to check any of those so I assume I am good to go, right?
Also, when setting the phone in flashmode there is no icon to indicate you are in that mode?
If I understood correctly the whole back up TA thing or you will lose it only happens if I unlock the bootloader so I think I am fine not checking any of those option to exclude but better safe than sorry.

Don't worry about your TA partition unless you're going to unlock the bootloader. It's safe, and flashtool won't and can't delete it. The only options you might be interested in is wiping of data, appdata etc. so untick those if you don't want to delete everything on your phone (but it's brand new, so my guess is that you don't have that much on it right now)
There are no icons or any signs when you're in flash mode. Flashtool will tell you that you're connected through flashmode and that's that

What happens if you lose your TA partition? I never backed it up as I had no root and I did do a bootloader unlock via Sony site.

Thanks. mmm having issues with not installing the drivers.
Gonna try restarting. Still wont install drivers when I tried flashmode...all I see is the S1 Service with the yellow warning icon under Device Manager. Tried with the drivers from the Flashtool folder and nothing. :/

Once you flash a stock ROM again, X-Reality won't work, and that's about it.

Are you running Win7 or Win8? Win8 has some issues with installing drivers if i remember correctly, and you have to disable "something something drivers", or boot up in safe mode or something. I'm not sure as you can clearly tell

Sorry should have said that. Actually is Windows 7 64 bits. tried many usb ports too.
FINALLY! LOL
I was installing the Ultra dirver when I should have been selecting Flashmode and fastboot from the list! LOL
Looks like I got a tool here : http://forum.xda-developers.com/showthread.php?t=1886460

And every time I think I am finally on my way, something happens!
My guide is sending me to vroot but that has been taken down so now I am not sure what to use to root :/
This is the guide I was using.

I saw some Kingo app, maybe I will try that.

---

Yeah, use Kingo

Hey man thanks for being with me through the whole process, appreciated!
I just finished the rooting and didnt have to do the CDA part as I got the OTA 257 upgrade now downloading.
Then I will back up TA and finally time to flash a ROM...now I must decide which one looks good!

Remember to use OTA Root Keeper before you update to 257.

Oh yes, I did the whole guide, Survival mode, OTA keeper and I am on 257 and rooted! Plus just finished the TA back up so only need to unlock bootloader and I am in business!

---

Nice! To unlock the bootloader, just go to Sony's Dev site and request your unlock keey. Then use flashtool to unlock it. Note that unlocking the bootloader might wipe some stuff (again), and if you can't find the root app when you power it on again, don't freak out
I'm off to bed, so you're on your own now

I am dead then! LOL
Just got an error your phone bootloader cannot be officially unlocked even thought the service menu says it can be unlocked.
More fun all night for sure.
Good night!

Ok so I got it unlocked and recovery has been installed. Do I have to now restore the TA? I ask as from I understood, we backed it up because it gets wiped out during the unlock thus logical step would be to restore now.

If you restore TA then your bootloader will be automatically locked.
