official update after rooting without flashing ?

hello
is there any way for have official update after rooting without flashing the rom ?
is there anyway to unRoot Xperia SP ?
Thanks

You can unroot your phone flashing a stock ftf file via flashtool.
As about updates, many members here upload ftf files once released, so waiting for Sony to release the update on your country, from the moment you can flash the ftf file some hours after the release, is kind of useless l (just my opinion mate).

Custom kernel lets you get the whole control of your device. You can use it for better battery life, overclock etc. All custom kernels in order to be installed, you have to have unlocked bootloader.
But, when you unlock the bootloader you void your warranty, you loose bravia engine and you can't update using Sony pc companion.
You can still though relock your bootloader by flashing via flashtool a ftf file that you can find on development section.
If you want to relock your bootloader, I suggest you to download an ftf file of the update and flash it and after that flash the ftf file in order to relock bootloader.
Flashtool is an app for pc that lets you install ftf files.
Ftf is the extension of the update that Sony releases.

so what exactly is a (the) tft file?
and how can i upgrade the phone?
is it also possible to use new android 4.2.2 (from sdk) like google nexus?
sorry but i dont know anything about original software from sony, always had custom rom on my lg ^^

No, you can't use LG files because it's not compatible with your device mate.
Ftf files are the format of the stock file. When users download an update from pc companion, they create a file so other members can use it even if in their country the update is not released.
You can check how to use flashtool on YouTube. With flashtool you can install ftf files.

i already used flashtool but i just didnt know for what and i just used it to install the xperia Z drivers (dont know why i had to use them for my c5303, others didnt work)
i used this kernel forum.xda-developers.com/showthread.php?p=42642971 and flashed via fastboot (just oldschool and how it worked ever on my old lg ^^)
by the way: it was a .elf file, not tft i think ^^
okay i hope i got it now. it is for: - samsung devices (only) and - necessary for using the original rom?!
but the last questions:
which kernel do i have to download to update? (german)
and: do i have to save the data? (dont have CWM on this phone, but titanium Backup)
sry for the dumb questions, but this is all so complicated for this **** phone (i hate it, but lucky it is not mine)
Offtopic:
for my lg i installed fastboot, download CWMrec, downloaded a custom rom, rooted, installed everythink, all done nicely :victory:
for the nexus 7 it was even more simply. used a nexus program, type a few numbers, all done
for this phone i had to install like a bunch of programms, had big problem with drivers, read dozens of sites (the technical one are not so easy for a german guy ^^), had to register imei, unlock bootloader and so on... very much crap for a 350€ phone... with old android 4.1.2

I really don't think you should be messing with unlocking bootloaders and playing with the kernel if you don't even know what it's for.

[Q] Rooting z1 c6902- INDIAN version .757

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

http://forum.xda-developers.com/showthread.php?t=2261606 -using this page for xz dual recovery install
what does this line of the section means????
""
When installing custom ROMs:
Be sure to flash XZ/ZL/TabZ/Z1/ZU-lockeddualrecovery[VERSION]-BETA.flashable.zip from http://nut.xperia-files.com after installing the ROM and before you reboot, this way you will not lose recovery!

Revert to stock.

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.

Need c6606 .283 firmware

hi guys,
im in need of the .ftf for my c6606. i have searched everywhere and cant find a damn thing for the 10.5.a.1.283 firmware. before my phone officially got the update for KK i decided to flash the customized firmware and it changed my phone to c6616. when trying to restore my phone it says that there is no firmware to download in pc companion. the reason i want to start fresh is my phone has issues with mobile data sometimes and even on wifi, data just wont load.
thanks guys

Follow part 2 of my guide to package your own FTF using Flashtool. Just make sure your installed version of Flashtool is up to date.
Once you've done it, you can share it in the general section to help others looking for it.

Thanks for the reply. I want to flash the baseband that is for the c6606. By doing it that way would there be any issues? Or should I just root the phone and change things in the build prop so that it says it's a c6606 and hopefully it will update that way

Just try what he said,i did that yesterday and all went well,just see if you do it right!

So after trying a few firmwares I had issues with phone kept restarting. So I wiped everything and flashed back to the available c6606 firmware and got ota for 4.3 after that. Now that I'm on 4.3 it says I'm on the most up to date fw in PC companion and on phone. Sony website says most up to date is the .283 KitKat fw. Any reason why I can't update?

Flash modem and/or rom, will unlock it?

My friend has a Xperia Z1 C6903, his phone is locked to "Three" in UK. I read that flashing a custom rom will not unlock his phone, only flashing a unlocked modem will. I haven't find a way to download and flash modem. I found this thread. Should I try all these steps or is there any way to flash an unlock modem like ftf files?
