Hello developers and xda members!
Some months/weeks ago I asked about rooting and warranty.I got some answers that if I unroot it or use SEUS I will not loose warranty.
This time is about roms and locked bootloaders.
If I install a CWM Recovery then flash a ROM do I void warranty?If yes is there anyway that I can make it so it's like I never flashed anything so the warranty will still last?
If yes what is the best rom I can install for LOCKED bootloader(I don't want to unlock it)?
I want a rom with good battery life + camera (I don't care if it's not 100% perfect but at least better than the stock one!)
Any answer would be helpful!
Thanks

Already searched but I can't find exact answer.I really don't want to loose my warranty!
Also I care for the exact model (Xperia SP) and not for others

Even if you unlock your bootlader you wont loose your warranty (if that is the reason you are not doing it).Just make a backup of your DRM keys and the unlock code and keep it safe.

I don't generally want to unlock bootloader.
Even if I don't unlock it and just install a rom(e.x Existenz) would I need to backup DRM keys?
Also can you give me a SAFE tutorial about backing them up?
I also asked about a good rom that has a good battery life and camera than the stock one.
What's your opinion about roms?What is the best based on your opinion?

If you wont be unlocking the bootlooder, you dont need the backup.Here is the thread with anything needed to get started with your phone: http://forum.xda-developers.com/showthread.php?t=1701644
I've never used the stock or other based on it (I use 4.3+ ROMs ), but other forum members say that Existenz is the best one out there.Currently, I am using the leaked 4.3,but it is for unlocked bootloaders.

Why would I need the list of things to scan with a NFC enabled phone?
Anyway so I will not void my warranty if i flash a custom rom and then "format" it with SEUS?
That's my point

nope, SUS will just repair the phone, leaving no evidence of root or ROM

I will proceed installing Xperia ExistenZ rom and I hope I will not brick my phone!:fingers-crossed:

Oops..wrong link!Here s the right one : http://forum.xda-developers.com/showthread.php?t=2354704
P.S. Im not sure but I think you will still have your warranty.Back in the days, when i had my xperia x8 and it got hardbricked, I lied to my operator that it got fully discharged and it never turned on again.The trick worked and it went to Sony with a custom ROM inside of it .Anyways..today i had to revert to stock, because the tutorial for the leaked 4.3 said so, but i encountered a problem - SUS said that my phone has modified software and it didn't complete the operation.I had to flash an .ftf image file with flashtool.But after all, It was successfull.
Ehm I got a question.At the install instructions of Existenz it says
Flash the rom.
Flash NUT reboot fix: http://forum.xda-developers.com/show....php?t=2317432
Flash 12.0.A.2.254 kernel only with flashtool (see FAQ).
As I see NUT reboot fix is for Xperia Z...Do I need to install this?Do I also need to install .254 kernel only again?At the FAQ it says about How to flash 6.2.B.1.96 Kernel with flashtool <- but this kernel is for Z...What happens?
Should I flash the rom then reboot my phone and OK?
Should I flash the rom then reboot my phone and existenz rom opens and then flash the NUT reboot fix?
Should I flash the rom then instantly install the NUT reboot fix?
Should I also install the kernel (12.0.A.254)?
I am kinda confused :/

1. Flash ROM
1.b Reboot phone
2. Use .bat from NUT (I used it after OTArootkeeper failed and I couldn't mount /system r/w)
3. Flash the kernel with Flashtool
Step 1b and 2 depend on what you prefer, flashing the fix or rebooting and let the computer do the fix: http://forum.xda-developers.com/showthread.php?t=2317432
You can use NUT for the SP. About the kernel I'm not sure. I am on LB atm.
Hope this helps (except for the kernel of course)

Well, I've no idea how much longer.. Should have been here in December..
I didnt backup before flashing, and now have false firmware, no sim signal, no wifi, battery heats as hell, and so on and so on...
I opened my Sony Xperia T LT30p- and found the original customization number and all that.
Its: "1266-6442 LT30p/Mobile Phone/Telekom.de DE (Germany)/Black"
So if anyone can help me to post here or a clue to find that firmware, he would be the God for me !

This is quite strange
1) Locked or unlocked bootloader?
2) Have you ever flashed a custom kernel?
3) Have you ever flashed a custom rom?
4) What's your original firmware customization number? EDIT: I've just seen that's 1266-6442... is this your ORIGINAL firmware? Where do you live? In Germany?
5) Rooted? CWM?

I can have locked or unlocked, thats not the problem.
Custom kernel, roms, rooting CWM and so on, i never did that, just flashing with flashtool :S
and yeah 1266-6442 is the original customization number, and i live in belgium, but 20 minutes away from Germany.

Ok, yes, I know how it works...
I just asked about the bootloader status, because sometimes some people mess with bootloader, kernel, flash from recovery, flash with Flashtool... and so on... WITHOUT the understanding of what they're doing... and come here complaining... do you know what I mean?
OK, now, I know how to help you.
1)
There's a method to download and install the original firmware directly from Sony.
But you need to be rooted. So, are you rooted?
2)
Your customization number is wrong.
1266-6442 doesn't exist.
That's maybe the number of your model, but it's not related with the firmware.
The right number for Telekom Germany is 1265-9144
The customization number is inside your software and can be found pressing *#*#7378423#*#*, inside Service info --> Sofware info --> Customization Version.
Give me that number please, so I can understand what's the software working now on you device.
3)
You said "I didnt backup before flashing, and now have false firmware, no sim signal, no wifi, battery heats as hell, and so on and so on.."
Ok, please, explain better what you did.
Have you flashed what kind of rom? Via recovery?

And i currently have 1265-1620_R1J, flashed it yesterday just so, its CE Region i thing, 4.3 version, build .295.
3)Yeah, i first had the original Firmware on my phone, had the 4.2.2 version, and then the official software came for my phone and the T-Mobile provider i think.
And then, the 4.3 is just S**t, as i sad it, just problems, and i just want the previous version, because it worked perfect.
so i just was flashing all the other firmwares, especially the 4.3, from all the other regions, i thought maybe they will work better, but nope.
And when i try to flash previous versions/firmware, it just comes to the animation, after the sony and xperia logo, and restarts over and over again :/
And no, no roms, or recovery, i didnt do anything of all that, just flashing firmware with flashtool.

Ok, now I've understood what's your situation.
It seems that when you flashed 4.1.2 firmwares, the process was not compete for some reason.
The list from which you get that number, is about all kind of xperia T... and is different from the firmware list.
The problem is that you lost your previous original number, maybe it was 1265-9144... and you can resume it only with root and a little bit of experience... and actually I'm not sure you would be able to handle this kind of hacking stuff.
Anyway I'm quite sure that 4.1.2 from CE is perfect for your needs.
Try this one with Flashtool: http://forum.xda-developers.com/showpost.php?p=42393403&postcount=29
This firmware is perfect for any european country: I tested many times and is one of the best.
But before flashing, recharge your battery to the maximum. And be sure that the flashing process is complete and without errors.
Just try and let me know...

This kind of issue is called "bootloop".
When it happens, try to push "power button" + "volume up" together.
The phone will turn off.
Turn on again and if there's bootloop again, repeat the procedure on and on and on.

I can't answer to the first question.
You are the first with this weird problem and I'm beginning to think that something is broken inside your phone.
Bootloops are usual when something is wrong with kernel or system, but if you say that flashing went good and this appears only with 4.1.2 , I really don't know why.
You are not rooted because you've never done before and anyway every time you format the system (flashing with Flashtool or via recovery) you lose root.
So you are not rooted for sure.
The problem now is becoming bigger, because there's no way to root a 4.3 firmware directly.
But... guess what? You have to root 4.1.2 before and then install a 4.3 already rooted. :crying:
The only way for you to root 4.3 directly is to unlock your bootloader, but this means that you lose warranty and DRM keys (that are needed to let work some functions like Bravia Engine).
Actually you could save your warranty and DRM keys with a special backup (called TA backup), but.... guess what? You need to be rooted!!!! :crying:
The second way is to try to install 4.0.4 ice cream and root it. It could work.
I give you this link https://docs.google.com/file/d/0B55PDGQqCzReV2dFSjFSNnlLLVk/preview?pli=1
It's 4.0.4 italian version...
Try this... and if it doesn't work, the only way is to unlock your bootloader losing warranty and drm keys, sorry...

LOL :cyclops: as you wish...
1) Flash 4.3 with Flashtool
2) Unlock your bootloader on Sony official site following all the instructions: http://unlockbootloader.sonymobile.com/instructions
3) Once it's unlocked, open Flashtool and re-flash 4.1.2 CE that I gave you and you tried before: http://forum.xda-developers.com/showpost.php?p=42393403&postcount=29
4) Don't turn on. Download Doomkernel here: http://d-h.st/4kK
Unpack the .elf file inside the zip
5) Open Flashtool. Connect the phone to PC keeping pushed the volume-up button. Now the phone is in fastboot mode. Click on the lightning symbol, select fastbootmode, select kernel to flash, select the .elf file extracted before, done.
6) Unplug the phone. Turn on and you will see the doomkernel logo... and now I hope that you finally enter into 4.1.2 firmware without bootloop.
7) To root: you need to copy this file http://download.chainfire.eu/396/SuperSU/UPDATE-SuperSU-v1.94.zip to the internal memory.
Turn off. Turn on pushing volume-down repeatedly, now you enter into recovery, now install the supersu zip and reboot.

5) Open Flashtool. Connect the phone to PC keeping pushed the volume-up button. Now the phone is in fastboot mode. Click on the lightning symbol, select fastbootmode, select kernel to flash, select the .elf file extracted before, done.
6) Unplug the phone. Turn on and you will see the doomkernel logo... and now I hope that you finally enter into 4.1.2 firmware without bootloop.
7) To root: you need to copy this file http://download.chainfire.eu/396/SuperSU/UPDATE-SuperSU-v1.94.zip to the internal memory.
Turn off. Turn on pushing volume-down repeatedly, now you enter into recovery, now install the supersu zip and reboot.

DAAAAAMN ! -.- :/ DommKernel logo is there, xperia logo, animation, and blocks again, restarts all the time.. I'm really desperate...
Now you have 4.1.2 with the doomkernel and the root, which is the perfect combination to do anything on your device.
If it's working, you can leave the phone in this situation.
Instead if you really want to go back to the original firmware, go here: http://forum.xda-developers.com/showthread.php?t=2334653
Follow the part A using this custom number 1265-9144 (t-mobile Germany). Remember you need root for this process!
Relock the bootloader http://forum.xda-developers.com/showthread.php?t=1924221
Plug to Sony PC Companion and Sony will re-install your original firmware.
My advice is to leave the phone unlocked and rooted with CE firmware

Damn.
Reflash 4.3 with Flashtool.
Download this Doomkernel: http://doomlord.xperia-files.com/download.php?dlid=VC1Eb29NS2VybmVsLXYwOQ==
Be aware: don't use the old doomkernel, but this one (v.09) that is specific for 4.3
Flash the elf file, as you did before.
Now you have doomkernel logo and you can enter into 4.3.
Now root it as I suggested in the previous posts (turn off, turn on pushing vol-down, flash suspersu zip, reboot).
Try.

Well dude im a bit confused now
The recovery mode is working too ( volume down pressing repeadetly", "Team recovery..." didnt catch up the rest of the name, but cant boot into the phone as i said.
Soo, what should i do now? You are my one and only HOPE !!
Hey guys. I was trying to install Cm10 on my sister's xperia T. I rooted it, installed recovery, wiped everything but after I flashed CM and clicked reboot, the phone is dead. I can't turn it on, I can't enter recovery mode, the PC isn't recognising it. If I push the on/off button it vibrates once but then nothing and if I push at the same time power on and volume up, it vibrates three times but then again nothing.
I know I forgot to do something while installing the ROM but please any piece of help might be extremely useful as I ended up with a dead phone and nothing I can do.

Did you unlock the phone's bootloader? Because custom roms like cyanogenmod require an unlocked bootloader for xperia phones. Also, try using the flashtool to revive your phone. This sounds pretty much like a soft brick. If I'm right, it's 100% guarandeed you can bring the phone back to life.

Who would use Emma when you've got Flashtool?
Also, you should really figure out if your bootloader is unlocked or not.

While waiting for an answer I downloaded flashtool, found a suitable ROM to flash (from flashtool website), installed the device's drivers, entered flash mode but then Flashtool showed me this

Are there other errors above the ones seen there?
What ROM did you Flash? Maybe you could try with ones found here on XDA.
Also, when you start up the FlashMode process in Flashtools, is your phone already connected?

Yes it was a problem caused by the ROM I was trying to install. I found one with stock 4.0.4 and flashed it and finally it came back to life.
And in fact it is faster than when it was running 4.3.3

Guess what: if you don't like the 4.04, you can find official 4.3 firmware files in this site. There's a collection of these things. Just search for them.

Thanks for the tip. In fact I'll make another effort to install CM and this time I'll make sure to follow every step properly. But comparing the two editions, I think 4.0 is smoother than 4.3.
Could not downgrade to get root
Hi all,
I'm a very big fan of this community, but only to read and learn. But now I need your help...
History: rooted my phone few months ago in the way told in this post. Everything went well, but last week my screen broke. Sony fixed it but also put latest software on it... and removed root.
Today I tried to downgrade to KitKat 23.0.A.2.98 again (stil had the FTF) to get root again, so I can put back my Nandroid backup. I didn't manage to get it working... after restarting after flashing when the blue screen appears before you are asked to unlock your SIM... my phone makes a pitching noise for 10 seconds and then reboots again. The process repeats itself again and again.
Fortunately I can flash the latest firmware back and my phone works again... thank God because a thought for a moment I soft bricked my phone.
Anyone a solution to get root? I'm now on LP 5.1.1
thnx!!!!
ciao
Valentijm
How did you downgrade? The normal way... means: using flashtool (latest version) and which settings did you use for flashing? ...and did you try downloading a different version and flashing it?

Hi Tom, yes I did it the normal way... latest flashtool and settings the same as before, so I checked no boxes. After that didnýtwork I tried something different, so checked all wipe options. I also tried a different version and flashed that via the normal way. That didn't work either... the only flash that worked so far was 23.4.A.0.546 / R7C. But that's way to new to get root via downgrading
So the flashing process did always work without problems? But the result is always as you described?
And if it's only about root... did you try Kingroot? Afaik it is supposed to work on almost all versions.
Another thing: I don't remember all options by heart (and can't check them atm)... but maybe try some of the provided options.

It's more that when I reboot after having flashed back to earlier FW my phone bootloops... so I don't even get a chance to continue and root. Very annoying!
My next move is to find another old stock FTF (probably not a Dutch one) and will try to flash that one with different boxes checked.
When I'm back home I can check for the one that I used (quite recently) when relocking BL and rooting etc. If I don't find the source anymore, I can maybe upload it for you.
Ok... so this was the version that I used... to downgrade and root:
D5803_23.0.A.2.93_Generic_GLOBAL_1286-9917.ftf
try this link maybe:
https://mega.nz/#!f5pXVAIZ!nWmaFU9d5ux6FOUI6Kdv3GK8RObswoZzxRwpQVEvpxo
There's an easy way to get Root on 5.1.1 without having to downgrade back to kitkat
- Unlock your bootloader on Sony's Website
- Search for a custom kernel here that is for 5.1.1 ( e.g. Androplus, etc )
- Boot into fastboot mode in Flashtool and flash the kernel
- You now get recovery because the kernel comes with a custom recovery
- Flash SuperSu's latest Zip file to get root
- Enjoy

Maybe be careful when recommending that without mentioning, that he would loose his DRM keys in that process... so I would always add the comment, that he should have a backup before unlocking. Or at least mention the loss of the DRM keys as a warning.

Happy to hear that! Enjoy your system!
Oops I almost forgot, but I always have my DRM Keys backed up
Me 2... but not everyone might know about it
But it did not matter in the end anyway
