I want to return to stock 12.0.A.2.254 firmware from an unlock XSP with cm10.1 and i have an ftf file (I downloaded from the inernet) as well as the flashtool to do so but I heard that flashing a stock ftf will relock the bootloader.Therefore I have three questions:
1) Will any ftf file work? Do I need a specific one for my phone? Will a Generic ftf from any country work?
2) If the bootloader is relocked,Will it be unlocked the same way as it was before? will the same codes (unlock key/IMEI) be used as when I unlocked the phone for the first time?
3) Is there a way to flash stock ftf without the bootloader getting relocked? If so then can someone give me detailed instructions?
I don't mind losing root access as long as the booloader is unlocked therefore I personally wanna go with the third method but I have got no Idea on how to go about it.Some help would be EXTREMELY appreciated.
Also I want to apologize if something like this has been asked before but I was not able to find a similar topic or a topic that could answer my questions.
Thanks.
P.S
I just found a "loader.sin" file in the ftf that I have.I don't know if it has anything to ddo with the bootloader or not.So will including that in the flashing sequence relock the bootloader? Does "loader.sin" have anything to do with the booatloader? Should I exclude it while flashing the ftf and will that result in a faulty flash?
Help would be appreciated.
It won't re-lock your phone's bootloader.
Any ftf will do but advisable to use back the one with same customization version that your phone came with originally.

I dont know my customization number.I mever checked for it neither did i back it up.Is there anyway to find it in cm or is it lost forever?
Then just flash any generic ftf for your phone model C5303 and it will also be fine. It will also be fine.

Read the second post in the all in one thread about creating a ftf file.
That will give you the latest software on a ftf file. However, if you have an update due and want to back up the system you are on its trickier.
Best bet is to do an adb pull of system and use dsixdas kitchen to convert it to a .zip file. But you will need to be rooted and have cmw to restore it.
My advice (As its given in the all in one thread) is to make an ftf as soon as you get your phone or as soon as you update in order to be able to flash it back when you want.
The ftf files you make from this method are completely stock.
EDIT
Unlocked but not rooted? What would be the point in doing that?
Thanks gregbradley,
It's unlocked because I got it as unlocked. not root because it's for my wife. she doesn't need a root phone. lol
Anyway, I guess this can't be done without rooting the phone. nvm then.

Ahh, you dont mean unlocked, you mean sim unlocked. Unlocked for devs means bootloader unlocked.
also, you do not need to be rooted to make a ftf file.
read the instructions in the link
Hi Gregbradley,
I tried to search the forum and googled it also, but I only can find the way to make ftf from the file that downloaded by using Sony PC Companion or SEUS. But not from the phone itself.
What I need is the firmware from the phone.

take a backup using recovery and use that system. img in dsixdas kitchen
but that involes rooting.
As i said in previousposts, thats why it should be done as sooner rather later.
Listen, just update and use the new firmware, dont sweat it
At the risk of being shot down in flames. What is the best way for going from 9.1.A.0.490 to 9.1.A.1.140 whilst retaining root etc?
I've got a std UK Xperia T, unlocked bootloader and generic european .490 and rooted.
Im looking for a basic step by step if possible, as I dont play around with the phone much. I managed to stuff up going to .490 which put me in a boot loop until I got it sorted. I prefer to avoid that scenario again if at all possible!
Thanks in advance
Update the official way via pccompanion and then rout again the same way you routed last time, probably by using bin4rys root many android method

No, In which case just flash .140 rom from the development section (My rom for example) but make sure it the right one for your phone, and flash it in recovery
Or just grab a FTF file of .140 and flash that in flashtool and then root like you did last time

Hi there
Just jumping on the "how can I update?" bandwagon, can I flash the Generic Central European fw onto my T? I am unrooted and have locked a bootloader. I'm in the UK and on EE. I have read the 1st post in the section saying this is fine to do, but I've also read an article on another website telling me that flashtool is only for unlocked bootloaders. Please can you advise?
You can flash using Flashtool with a locked bootloader and while unrooted.

Pccompanion = Only works on locked bootloader
Official Sony Flashtool (EMMA) = Only works on unlocked bootloader
Flashtool by Androxde and Bin4ry = Works on all devicex
Gave up after managing to get stuck on the sony logo.
Relocked bootloader, updated via SUS, unlocked bootloader and then rooted using bin4ry's method.
This is for my curiosity and many other users who I know are wondering the same thing, I've searched for this, but can't really find anything that answers it to my satisfaction.
So I'm running 4.3, with build number .290
I want to root my phone, but I know I need to flash .534 back to my phone. As far as I know, THIS will stop my sim being recognised by the phone. Do I then need to ROOT the phone, and then flash .290 again for the sim to work again.
So which .290 flash will I use? Just the normal FTF file for .290?
Thank you, I'm an active contributor to the forum, but I like to be super sure about what I'm doing before I do it, and I gather many other users do. The reason I'm asking in such detail is because my phone was rooted before, I updated (by mistake) to 4.3 and then flashed back to .290 where it stopped my sim working. Took me a few hours to work out how to fix it, as the pccompanion wasn't working for me!
Thank you!

If you want to flash the firmware you have, follow this guide from part B to part C, then you will have a ftf copy of your current firmware.
About the root thing, downgrade to .257 then .534 so you don't have the IMEI and signal issues. Then root and OTA to .257 and then, if you get OTA update to .290 go for it, but some people said that you will only get partial root access.
So you will have to either flash a prerooted firmware or unlock bootloader and turn off Sony's RIC and then root the normal way.
To unlock bootloader, just follow the instructions here but don't forget to backup the TA partition using this guide.

I have just purchased xperia z1 and has updated it to latest .757 and wants to root my mobile. May be this type of questions are already posted but i find some questions in my mind before rooting so I want too clear it out so that i may not be left with a bricked device
1. can the c6903 firmware be flashed on my c6902 without any problem ( such flash was not applicable on my galaxy ace and there was no any correct way, you are left with a bricked device, but I see only c6903 threads)
2. if so , can i flash the link of ftf on NUT thread (it is c6903 ftf----- else i have to go to ftf mega collection and flash c6902 IN ftf?
3. can the flash tool unlock and lock bootloader so that i get my warranty again ( will i loose root after locking bootloader ?)
4. does unlocking bootloader crashes camera? ( i think i read months before that 20,7 mp stop working)
5. if unlocking bootloader crashes camera shall i install Z1-lockeddualrecovery2.7.123-BETA.flashable.zip (8.47MB) from this site http://nut.xperia-files.com/ from flashtool ... if so plz tell how ..
6. how can i relock bootloader, if i unlock it?
7. what flashiing ftf withou ta means?
8. does flashing kernel, recovery and ftf are same ways i.e just put them in flashtool/firmware path and use "flash" button and follow flashing..(please do elaborate here, if u can add pics thanks). I read the noobs guide but it was for xperia x10.
9. After rooting-- flashing recovery-- all i have to do is wipe data, dalvik cache and install rom
10. i also got my back glass cracked due to my phone getting placed under my bed table while studying... i read many T&C of accidental warranty policy,, so is this reason a valid reason to get warranty,, how much will be the cost of changing back glass as accidental warranty is only 1 time useable..
At last thanks for giving your precious time and clearing my doubts

you only need to backup your ta partition if you plan to unlock your bootloader. By Unlocking your bootloader you will lose your DRM keys. Anyways having a backup of your ta portion isn't nothing bad.
Using flashtool and flashing a stock firmware will not unlock your bootloader.
2]
A stock firmware comes unrooted. Pre rooted means that the firmware comes with root integrated.
3]
PRF Creator is a Programm you use under windows
4]
You have to understand what a ftf file and a flushable zip means.
Ftf files are flashed with flashtool.
Flushable zip files need a custom recovery to flash. For example twrp or cwm or philz recovery. To get a custom recovery on your phone your phone has to be rooted.

PRF Creator is a stand alone Programm that doesn't require a phone.
It only needs files as input and the result is a flashable zip you must flash with a custom recovery

No.
This zip will launch a program called aroma installer. With this program you will be asked what you want to install.
For example the description of iHackers rom says that you have to choose between stock or custom kernel.
3]
To flash a custom rom or custom bootloader you must unlock your bootloader first. If not you can't flash anything custom.
You can unlock your bootloader with flashtool. For that you need the unlock key for your bootloader. You do this in fastboot mode with the help a flashtool.
Flashing a ftf the phone is in flashmode.
Fastboot mode and flash mode are two different states you can put your phone at.

I am not sure. As far as I understand yes if you choose locked bootloader.
Maybe some other member can help here too.
But to flash the zip you need a custom recovery. For a custom recovery you need root to install it.
Post #4 at ihackers rom Threads mentions the step to flash the rom on a phone with locked bootloader. Not that easy!
Answer is Yes. I've already tried iHackers ROM on my Z1 w/ locked bootloader. I don't want to be rude or anything but all your questions are answerable by going through some basic reading materials that are all available in XDA. I strongly recommend you do your reading first. We don't want you coming back at us saying you now have an expensive paper weight, or that you have lost some important audio, video, image, SMS, MMS, Contact, etc. on your phone. It would really help alot if you read the iHackers ROM thread as well.
You did state on your initial post that you want to keep things simple. Then I suggest rooting your phone, get rid of the apps you won't ever use and just keep it stock.

I just want to answer this and sum it all up.
Do i have to Backup TA before i use flashtool? i think if i do flashtool No, you don't need to Backup your TA partition to use Flashtool. Flashtool works for both locked & unlocked bootloaders.
i will lose DRM keys like sony features? (for locked bootloader) I'll treat this as a separate question. Yes when you unlock your bootloader you will loose your DRM keys, which is why you need to backup your TA partition first before you unlock your bootloader. But as I mentioned earlier - No, you don't need to backup your TA partition if you will not unlock your bootlader. And -No, it is not needed to be able to use flashtool.
What meaning by 'pre-root' firmware? It means it is a stock Firmware that has root access. It is basically your stock firmware that was ran through PFRCreator.
without root phone and unlocked BL, is it possible to use PRFCreator? It's basically like this... NOTE: This is a not-so-details procedure but it will give you an idea on what the PRFCreator is. So the answer is Yes, it is possible to use PRFCreator with a locked bootloader but you need to have a rooted phone with a custom recovery so you can flash the pre-rooted 5.1.1 *.zip file you made, then flash the 5.1.1 FTF using Flashtool
1. Install flashtool
2. Download a 5.1.1 FTF using XperiFirm (it's an icon in Flashtool that opens a FTF downloader that automatically unpacks and makes you a FTF that you can flash on your phone)
3. Download PFRCreator
4. Using PRFCreator you basically create your very own pre-rooted 5.1.1
5. Now you have Two(2) files - the flashable *.ZIP file (the file generated by PRFCreator) and the 5.1.1 FTF you have downloaded earlier
6. You will need to root your phone and install a custom recovery partition on your phone so you can flash the *.zip file you have created using PRFCreator, then flash the 5.1.1 FTF using flashtool
7.
