OK, NM, I figured it out.

[Q] Looking for a rom

Hi, Im looking for Xperia S stock rom with no junkie(with or without improve scripting)
A link to it, if there's would be appreciated. Thanks
You can't able to flash to Stock rom without unlocking the bootloader.
If you unlocked,you can do it with Flash Tool.
Flash tool:http://androxyde.github.com/Flashtool/
You can get the stock rom from here:

Reset a Ray ?

Hi guyz,
After messing around a bit with my new Ray, i realize i prefer it being factory pure, being able to get updates from Sony and use PCC and stuff like this, running the official rom.
I know how to get back to official software through flashtool, but i was wondering if there was any way to get my phone back to the way he was out of the box. Is there ?

[Q] Sending my Xperia Pro for warranty

Hello,
I cannot mount my SD cards in Android and also in ClockworkMod Recovery. So I decided to send it for warranty.
I currently have Xperia Pro (MK16i, Central Europe) with CyanogenMod 10.1, some non-stock kernel an of course unlocked bootloader.
I couldn't find any guide how to restore everything to out-of-the-box state and I would like to write some guide, but I need your help guys.
I guess that what I need to do is this: (in order)
Flash the stock kernel using Flashtool
Flash the stock ROM using Flashtool (as SD card is not working on my phone)
Lock the bootleader
I found this ({PRO} Complete List of Roms) great post with stock ROMs. I can find the stock firmware but I cannot find stock kernel. Could someone point it for me? Or is the kernel included in firmware?
Then I found this tutorial for Xperia Arc to Relock bootloader. It some file, I should flash it with FlashTool and it should lock the bootloader.
Am I right? Could you please revise my steps and confirm me or tell me what is wrong?
Thank you in advance

[Q] Please help. Phone from Hong Kong, can't update past 4.2.2.

Hey guys,
Thanks in advance for any help you can give on the subject.
I just bought a Sony Xperia Z Ultra from eBay, arrived a couple of days ago, in great working condition. The firmware installed is 4.2.2, and I can't upgrade past there.
I contacted Sony and they told me it's because the IMEI number puts it's origin in Hong Kong which is why I can't update it. The only thing I can do is contact Sony Hong Kong, and I'm having a difficult time doing so.
Does anyone have a fix or workaround for this situation?
I was thinking I could root it and put an upgraded version of android on there, but as I'm not sure how rooting works, I thought I'd ask if there were any alternative options.
At this point, I'm thinking I'm just going to have to send it back, reason being when I chose this phone, one of the main points was because of the soon to be released 5.0 update.
Thanks,

As far as I know you should be able to use flashtool and flash a stock ftf for your region, or wait for 5.0 to be released and then flash it.

Thank you for getting back to me.
I may wait for 5.0. I'll need to learn how to use a flashtool with android first.
Quick couple of questions. Would using a flashtool to flash a stock ftf require the phone to be rooted?
Also, do you know if there is anyway I could use the Google Play firmware on my non-Google play edition?

Flashtool does not require root. The GPe firmware has to be "ported" to run on Sony Z Ultra due to different partition sizes. For 4.4 there is the option to use it with locked or unlocked bootloader. For 5.0 it is only for unlocked bootloader.

Thank you again for getting back to me.
Do you know if there is a tutorial for both porting the GPe firmware and for installing 4.4 using a bootloader? As I'm not even sure where to start with this, I'm not even sure what the difference between a locked and unlocked bootloader is. But I don't want to use up all your time, so if you can point me in the right direction, I'd really appreciate it.
Thanks again,

It has already been ported here in this thread linked below, UB and LB are short for unlocked bootloader and locked bootloader. The second post has instructions for locked install, and a simple explanation of bootloader is a set of instructions for loading the kernel so locked will only load stock. The kernel is the interface between software and hardware as I understand it.

This thread is up to date if you wish to read up on rooting and unlocking methods. Please don't hesitate to ask questions as it would be better than stumbling into a mess that could be avoided.

Thank you for all the information.
I've done a bit of research, and read through most of what you linked.
I'm slightly confused. As far as I understand it right now, if my bootloader is locked, I can only flash official ROMs. If my bootloader is unlocked, then I can flash any ROM I want, as long as it's compatible with my phone, but I will lose the Sony Bravia engine if I do so, is that correct? I'm not too bothered about this, just curious if this is true.
Where I am really confused, is the part where in the requirements of LB Rom Port, it said
"Be on 4.4.4 firmware (only .108)"
I'm currently stuck on 4.2, and can't get my phone to 4.4.4 with either the built in software or Sony Pc Companion. Is there a guide somewhere on how I can upgrade to 4.4.4 without using the two methods just mentioned?
I've also had a search and not been able to find a 5.0 GPe ROM Port either, guessing no one has bothered with it?

I seem to have also lost the miracast screen mirroring after unlocking bootloader, if you root then back up the TA first it can be restored. I don't have any experience with pc companion, usually when it is mentioned it is because someone couldn't get it to work. In those instances flashtool is recommended to use. Here is a guide for flashtool. http://forum.xda-developers.com/showthread.php?t=2428319
And link for 5.0 GPe port.

STOCK ROM] [FTF] Xperia Z Ultra (C6833) 14.4.A.0.108 "US RETAIL"
I assume this one will be ok, though I'm unsure. My phones model number is C6833, and this was the only 14.4.A.0.108 ROM I could find, and as far as I've seen, that's the recommended one for 4.4.4, assuming I haven't done anything wrong.
And just double checking, do I Need to root the phone to put the 5.0 GPE port on?
Thanks,

I was able to use FlashTool to update the phone to the official 4.4.4 ROM, so that you very much for all your help.
I think I may just end up sticking with the Xperia ROM, in favor of rooting and installing a port. I'm actually really liking the 4.4.4 Xperia version.
Thank you very much for all your help, I really appreciate it, wouldn't of been able to do this without your help.

That's good that you got updated. If you decide later to try custom ROMs or the ports be sure to root, then backup the TA partition before unlocking the bootloader. If you wanted to stay on stock but add some customizations you could root and install xsposed framework modules.

[Q] CM12 Revert to Sony Stock ROM

Hi Guys
We have a Sony Xperia Tablet Z2 (SGP521), currently installed with a nightly build of CyanogenMod12 Lollipop ROM.
Some functionality is not working well, so we would like to revert back to Sony Stock ROM, can someone guide us on the steps required?
We understand that the steps is similar to flashing the ROM into the device, but would be great if someone can confirm the steps, including where we might find stock Sony ROM. We've looked through some of the forum posts but some are quite old posts so just wondering if anything might have changed.
Thanks in advance for any help!
Will this work?

Just do a full wipe and flash the prerooted zip linked above in recovery.
