Rooting, Unrooting and Warranty

Hello xda members!
I am using Xperia SP without touching anything.
I mean I didn't flash any roms - root it - unlock bootloader etc.
I wan't to root my phone but I am afraid of loosing my warranty.
I can see at some threads if I unroot my phone and repair it with PC Companion or SEUS it's like
i get back my warranty.
Is it true?
Thanks

Do whatever you want on a LOCKED bootloader. You just need to make a copy of your actual firmware, a .ftf file to use with flashtool. If you need to send your phone for warranty repair you flash the .ftf and it gets everything like new.

I am going to follow this guide [http://forum.xda-developers.com/showthread.php?t=2440375]
it requires me to flash some old kernel then root then flash the new.
Will this interfere with the warranty because I am flashing?
Or is it OK to flash?

I don't think flashing will affect your warranty, but if it does and you want to send the device back for repairs, just use SEUS or PC compagnon to do a repair

[Q] How to backup TA, MAC and IMEI with unlocked BL?

Greetings to everyone
I have already unlocked BL & rooted my 4.3 xperia Z1 with CWM recovery installed... the camera and everything works fine
So, how to backup TA, MAC and IMEI with unlocked BL? I want to avoid any furthur losing possibility of them
Sorry If this a repeated question but I have searched a lot before posting this
thank you

You can't Backup your TA if you Unlocked your Bootloader. You lost your DRM keys permanently. You will not be able to re-lock you bootloader and you are not covered by your warranty. Sorry but you should read carefully before do anything.

Yeah, too late, you should have done this before the unlock....

oh.. I hope everything will still fine .. but I saw option in flashtool to relock BL.. it won't relock my phone ?? ... and what is the safe way to update my device firmware when 4.4 kitkat arrives to xperia z1 ??? and what are the risks now ?? what I must avoid and never do ?? any advices for me ???... sure it's better to stay one 4.3 without root rather than breaking my phone
thank you

Should be all fine but the safest way was backup TA first because if one day happen something on your phone you can't go via warranty.

You still losing your DRM keys so even if he does it's compromise, no x-reality, bionz engine and bravia.

This is not a problem, the FTFs will be upload here on XDA like for .290 and Custom Roms as well.

This is what we said already, the risk is if you brick the phone and the warranty will not cover that.

You don't have to avoid anything just read carefully everything when you try to do something. My advice is now to wait for the confirmed and safe way to root or update. In your position you already lost the safest way so I will root, update or flash custom roms to enjoy the phone but remember, it's your own risk and responsability.

Ive done the same, came from HTC.....so I will still have all tge features unless I flash say cm11 and try to go back to a Sony based rom?

You can't root this version directly.
You have 2 options.
1) Unlock bootloader.
2) Downgrade to 4.2, root via vroot then upgrade.
More details here.

no use downgrade than root. will lose root after update to 290/136.

You can always use nut method for upgrade but it doesn't support this version i guess.
or you can always go for a custom rom which is prerooted.

i know there is a method will sure work.
-use flashtool flash custom kernel
-go to cwm flash a zip file (update_supersu.zip) provided by someone in xda, credit to tat person!
-finally flash stock ftf with only kernel.
-done! rooted!

@chunlianghere, @thalada, What are you doing People? From all the links just one is correct, for .290. Also NEVER give advice to Unlock Bootlader because users cannot be aware of the risk doing this like lose Permanently DRM Keys and Warranty, FOREVER. Because if you do not advice of the risk someone can Unlock the Bootloader then lose DRM keys and if so it will NEVER be relocked and warranty will be void permanently, so before give advice learn what is all about!
@SpawnCube, the .136 cannot be rooted directly but can be Rooted with the method by NUT for Locked Bootloader. If your Model is C6903 you can downgrade directly to .534 with FW provided by NUT to not lose IMEI, then Root with Bin4ry, then Update to .290 with the instructions given HERE, when you have .290 rooted you are ready to update to .136 with the same method HERE.
For different Models the downgrade have to be done differently, downgrade to .257 FW First, then to .534 FW to not lose IMEI, but you will update anyway so there is no problem even if you will lose it.
Watch the Video Tutorial How To in the first Link for .290. It will explain all.

That sound like you try to be smart without know anything about it. So then you should go back to read the whole Xperia section before Post.
If you Unlock Bootloader you will lose DRM Key permanently and you warranty will be void forever. To avoid that You have to Backup TA, to Backup TA you need Root, but if you Unlock Bootloader before have root you will lose DRM. It is clear NOW?
I think only Samsung lose IMEI? Read again the whole Xperia section and Rooting Section.
If you love Samsung because is not so complicated then you are in wrong section.

actually i dont care much about DRM key anyway. send for warranty only if hardware is spoilt. the most ask them do last warranty repair.
if DRM key n warranty is so much important, than sony would hav "Bootloader unlocked: NO" for all phone in the world
actually sony doesnt do the warranty n repair. it depends on the company in tat particular country. like example for doomlord, his one is only flap damage, but can get 1 to 1 exchange. tat shows tat how good the company is in tat country.
unlocking bootloader n rooting is pretty much standard.
technology n software is improving at a fast rate. the most i get a latest newer phone.

Ok, here you are right but you have to understand that, what is not important you, it may be important for others, especially when we talking about Warranty.
We are here to give advice, then we should do this in the right way and inform users of any risk.

hey eclyptos, hope you still around this thread.
i quite agree with you, since i am one of those who care about warranty.
I hope it's fine to make a question about rooting here 'coz i can't make post on there. anw, i've been trying to follow the steps on here, but i find some trouble.
My status is :
Device : Xperia Z1 C6903
Build number : 14.2.1.136
what I did was :
Installing Flashtool 9.13 on PC
Download C6903_14.2.A.0.290.flashable.zip and put it on my first page of SDcard on device
Download C6903_14.2.A.0.290.Stripped.tft inside flashtool/firmwares folder on PC
Install TWRP on my device (can’t be used, root needed), can’t create a backup *step 5 failed*
XZDualRecovery Question : I’ve download it, connect my device to PC then enable USB debugging mode. Execute the install.bat from XZDualRecovery and choose number 2. Does anything really happened? *step 6 failed?*
Then I install the flashmode and fastboot drivers from flashtool folders. Tried to flashmode C6903_14.2.A.0.290 Brand Generic NCB but it stopped halfway.

The Video Tutorial on that thread explain very well what you should do, did you watched it?
You have to downgrade via Flashtool to .534 FW provided by NUT to not lose IMEI, Root the Firmware with Bin4ry, when you are rooted instal Dual Recovery, then follow the instruction to update directly to .136 from HERE.
All the files you find in .290 thread, Post #3, Watch the Video, then follow .136 thread.

in which firmware u unlocked the bootloader and rooted the z1?

If you Unlocked your Bootloader when you was on JB 4.2.2 then you upgraded to KK 4.4.2 then that's the mistake...

Something wrong here, i can confirm unlock bootloader on 4.4.2 can't stop camera function. (i unlocked my phone on kitkat firmware 757, all working fine)
I think you did not backup DRM keys too?

Something wrong here too, it not come out of box with Kitkat, so I presume you was thinking you have it but you don't.
If you brought it used then different story, but the story of the phone we don't know.
So I don't know how to help here as Unlock Bootloader on 4.4 do NOT Breaking the camera functionality.

I bought it new from Sony with Kitkat on it in middle east -Dubai

The issue is being sorted via PM with me.
However, this is a synopsis.
The OP unlocked the bootloader on 4.4 - Camera works.
Then, instead of just flashing a custom kernel to gain root, the OP followed a guide for a locked bootloader to gain root. Once they downgraded to 4.2 the camera broke.
In order to fix this the solution is
1) Relock the bootloader (by restoring the TA partition if a TA backup was made, in this case not, or by using flashtool)
2) Use pccompanion to upgrade to latest FW
3) Re-unlock the bootloader by the official method (Or flashtool, if it was re-locked with flashtool)
4) Flash a stock based custom kernel
5) Install SuperSU from the play store.

I don't think so if you unlocked on 4.2
If you unlocked on 4.3+ it wont break anyway
try relocking the boot with flashtool, upgrading by pccompanion then unlocking again with flashtool
