[Q] Question about ROMs and warranty

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

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)

Read forum rules, it clearly says "DO NOT POST QUESTIONS IN THE GENERAL SECTION"!
To your problem: are you running 4.2.2 or 4.3 now? In your post you say you flashed 4.2, but then you say you're running 4.3
Try to reflash a stock 4.3 ftf. This should solve your problem

Im running now 4.3
I DON'T WANT STOCK 4.3 FTF
It's bad for me the both versions are bad i want 4.2.2 the best

Do you want a custom Rom or stock 4.2? Because if you want a custom Rom you should flash 4.4....
If you want to stay with 4.2.2 reflash a stock ftf

If you downgrade, you need to wipe everything, or you may get a bootloop or errors like the ones that you're seeing.

Then you should download a ftf file and flash it, but don't forget to wipe as kingvortex mentioned

I know i most wipe data when using flastool i tried upgrade from 4.2.2 to 4.3 without wiping data its worked without bootloops but the bug of my 4.2.2 now in 4.3 i flashed 4.3 again with wiping data now its fine :good:
The most thing i liked in 4.2.2 is the ROOT
Now can you give me link for a bug free 4.2.2 stock ftf? If you cant now dont do it now do it when you not busy
I googled but i didnt found clear one and i cant try every4.2.2 ftf because my internet speed slow 80kb\s
4.3 will be perfect if i ROOTED it
And i heared some one say using flashtool much may damage my CPU is that right?

You can find a stock 4.2.2 .ftf file over the net or even here on xda and use the flashtool. When selecting the firmware to flash, also check the "reset customisations" option (down right) and then follow the common flashing sequence. This might fix your problem. Otherwise, use other version or pc companion or update service.

If it would be so, then many people out there wouldn't flash their phones over and over again.

how to make full wipe without CWM ? Just factory reset in settings ? I'm back to 4.2.2 via flashtool but without full wipe...

As soon as you have a backup of the stock firmware (which is an .ftf file in your case), you can experiment with your phone as much as you want. That's what I do anyways....

You can do a full wipe from flashtool just tick the user data box in flashtool you can find it in right corner when select an ftf file

[Q] Downgrade from 4.4.2 KK - 4.3 JB. Help.

First of all, I've tried searching and reading tons of forums/guides the past hours, but I can't get this to work. So please excuse me if I've missed something
I'm trying to downgrade my Xperia Z1 from (the horrible) KK update 4.4.2. to my stock 4.3 JB. I've tried flashing the following FTF's:
C6903_14.2.A.1.136_Generic Nordic NCB_1276-9897.ftf
C6903_14.2.A.0.290_Customized NCB 1276-9897 (Nordic Combined).ftf
C6903_14.1.G.1.534_1276-4314_R2A.ftf
All found here!
No one works. I keep getting bootloops (I can se the startup animation, then it restarts). I manged to get my phone working with using the orginal KK FTF (C6903_14.3.A.0.681_Generic NCB 1276-9897 (Nordic).ftf).
Could somebody please help me and figure out what the problem is? I've added my Software Info as an attachment.
Thanks for any replies!

Really weird, if you flashed them correctly from Flashtool v0.9.15 they should work, check the version of your Flashtool if is correct. Also try the one (FW .534) provided by NUT for C6903, here.

I used Flashtool Version 0.9.15.0. and yes, I believe so.
Flashmode->Choose FTF->Wipe Appslog and Cache, uncheck Data->Flash
That looks like 4.2. FW, and a custom ROM? I would like to have the original 4.3 .

Yes, but if that will work then you will have more chance to Update via Flashtool to .136 FW 4.3 and maybe get Root too (Optional).

Hm.. I'm not sure about a custom ROM, It's a road I'm not quite familiar with, if you understand .
There isn't any troubleshooting I could do that you can think of? Have i selected the right FTF for my phone? Is it actually possible to downgrade from 4.4.2. to 4.3?
EDIT:
If I'm going to delete my data, exactly WHAT am I losing? I want to know what I have to take backup of before trying that out.

OK, then, wipe everything and make a fresh installation of 4.3, I think this will work. Backup anything what is important to you, Pictures, Vids, or Data games to not going to download them again. I don't know, wipe everything..

You will find all on XDA just by searching the right Words.
You have to use "Flashtool v0.9.16", download the FTF from "Mega Collection" for your Model (C6902/3/6). Download the FTF "Generic" or "Commercial", the customization have nothing to do with that, put that FTF in the Folder of Flashtool, Run Flashtool, Flash, select the right FTF, put your Phone in "Flashmode" and when Flashtool asking connect the phone via USB to PC, Wipe everything Data, Cashe, Appslog. Done.
Do not ask for step by step, all what you have to know I already wrote.
Clik Thanx.

Sure you can
9.2.A.1.210 is better because it's the last.
If you flash with Flashtool you can't root, because there's not a direct method yet.
The only way to keep root, is flashing a pre-rooted 9.2.A.1.210 via recovery.
FTF files for Flashtool are in General section, instead ZIP files for recovery are in Development section.
Good luck

1) Install recovery
Download here: http://www.androidfilehost.com/?fid=23269279319202175
Take your phone, go to settings, developer options, turn on and select USB debugging.
Connect the phone to PC now.
Unpack CWM4XperiaT_v8i_JB.zip
Run install.bat/install.sh
Follow the instructions, remember that your device is V, keep an eye on the display of the phone and give root permission when asked.
After the end of the process, enter into recovery like this: turn off the phone and turn on.
Immediately, try one of this combination:
Press repeatedly (not holding) power button until the phone vibrates
OR
Tap repeatedly the screen
2) Once you're in recovery, make a BACKUP.
So if something will go wrong or simply if you want to go back to 4.1.2 because you don't like 4.3, you will be able to return to the present situation just resuming this backup.
3) Install .210
Remember that you will lose all your data and apps. Instead what is inside internal memory and SD card is SAFE (backup included)
Download and install Flashtool
Download THIS and move it into the directory C:/Flashtool/firmwares
Download .210 zip file HERE and copy it into the internal memory of your phone.
Turn off and go into recovery.
Make a wipe data/factory reset.
Then install zip from sd card, choose zip from sd card, select .210 zip file.
When it's done, select POWER OFF (be careful, DO NOT select reboot).
Open Flashtool, click on the lightning symbol ("flash device"), select "Flashmode" and click on "OK"
Now select LT25_9.2.A.1.210_1268-6904_FIX4.3 and click on "Flash"
Wait for a window to pop up
Now take your phone, push the volume-down button, keep pushing and connect to your PC
Once the flashing process has started, release the volume rocker as soon as possible
NEVER disconnect the USB cable until it's finished!!!
Turn on and enjoy! :good:

1) If you want to keep root you must download LT25i.210_nor_deodex_root_philz_v1.zip that I linked above, since it's already rooted.
2) When you flash zip via recovery you don't touch the old kernel. You flash only the new system. After that, you need to flash the new kernel, so you need Flashtool with LT25_9.2.A.1.210_1268-6904_FIX4.3
3) When you switch from an Android version to another, a full wipe is always recommended. A partial wiping could give strange behaviours.
Therefore it's better a fresh installation of the app and then (when possible) a resume of the backup offered by the app: for example I'm quite sure that Whatsapp has a backup option within its settings. Use THAT option if possible with any app. Right?

Wipe cache is already included into factory reset.
Wipe dalvik cache is not mandatory in this case... do it if you want
Anyway all wipes will be repeated by Flashtool, so don't worry about that.
In Flashtool you have to change NOTHING, since yours is a brand new installation. Just flash.

works with lock bootloader ?

LOL... I'm not so noob.
Yes my method is for locked bootloader.
Unlocked bootloaders have to flash another kind of kernel.
The kernel you're installing is the original one.
And no, you can't unlock an Xperia V through Flashtool. It's impossible at the moment.
The only way to unlock is getting a code through Sony site!!!
This rule is valid for all 2012 devices onwards.
You're too anxious

Unlocking is mandatory for new Xperia that can't be rooted directly, because they are too new and they've been released with 4.3 or 4.4
We don't have this problem because we have 4.1.2 that is easy rootable, so we can install recovery and do everything we want

This is for locked. Stop asking. Don't worry.
I did this million times with locked bootloader.
During the process does your phone ask for root permission? Do you tap on yes?

C6903 - Baseband Unknown Fix

Hi Experts,
I have searched the forum and after flashing for three sleepless nights, I am still struck with the unknown baseband issue.
The details are:
C6903
BL Unlocked & now its locked using Flashtool (DRM or TA backup is unavailable )
Currently the phone is struck in boot loop in .534
Used Flashtool ver. 0.9.22.3 & 0.9.18.6
Latest EMMA & Xperia Companion
My phone hanged when listening to the music and when I force restarted the unknown baseband showed up. While flashing I got the baseband back after flashing .518 however it hanged again after two days and I lost the BB
Now I am struck in boot loops on .534 and .518 both. I can boot into .290 successfully. Can someone please guide me to the correct method of restoring my IMEI permanently.
P.S. As per my short experience with C6903, I believe something stops the boot of .534 and .518 after first boot. Means I was not able to boot into .534 but accidentally when I flashed .518, my phone booted successfully. However now I am unable to boot into .518. May be I am missing the piece of puzzle that an expert can provide.
Thanks in advance~

Thanks for your tip but I have already tried and still get struck in bootloop.
No .534 FTF has booted until now and I have used 6 of them already...

An update is that I have rooted 4.4.4 and installed recovery...
can someone tell me where can I get .534 zip to flash as the files I have are giving me verification error on TWRP.
Thanks in advance...

I have tried to use NUT fix but the files are not available for downloading.
I would really appreciate if someone can direct me to the correct path. I am almost giving up now...

May be file deleted , other options you can create flash zip using PRFCreator , search and download ftf file from here .

Hi again, Really appreciate your help.
I have tried flashing a number of files but still in vain. What I really can't understand is .518 was the last 4.2.2 rom that booted successfully on my phone and brought my baseband back. Now .534 and .518 are both ending in a bootloop at Sony animation Really driving me crazy...
As a side note, can you tell me if the modem files in the link below are useful for this issue?

By the way I am really amazed with the Z1 ability to handle abuse that I have thrown at it during the last 2 weeks
Changing phone is not an option for me right now. Using Nokia 1100 after a long time seems very uncomfortable and can't do it for long

Thx for the tip but its not working.
My SIm was only detected once thats when I installed .518 but it lasted for a day and got held. When I force restarted the phone it was again missing baseband.
Now it isnt booting into .518 or .534.

Experts am I asking something that is un-do-able...

Guys shall I give up fixing this phone
I loved this dead beauty...

Hi, tried to flash with different cables as I don't have Sony original cable with me but the results are still the same. No luck with .534 and baseband is still unknown...
I understand this is a free community and people are free to determine if they wanna help someone or not. However I just wanna know if this is repairable or shall I just forget about repairing it. Any inputs will be highly appreciated.

I have realized that the phone does not shuts down with the power button in any bootable rom. Also sometimes the baseband does appear soon after installation but it disappears as sim is inserted. Can someone plz help me understand whats going wrong. I really love this phone...
