Way to debrand Xperia L c2105

Hello everyone!
I'm wondering if it's possible to debrand my xperia and install an original Sony firmware just changing my costumization number in the build.prop file and connect the phone to PC companion and make a repair installation.
Everything with bootloader locked and phone rooted.
Finally using this guide step one and two http://forum.xda-developers.com/xperia-l/general/guide-download-firmware-customization-t2355982
Is it possible? Can anyone confirm that? Or twill there be some problems?
Thanks a lot!!

i dont know if repair via pcc can solve this kind of problem, but i can say the simplier way to do that is flashing fw ftf via flashtool without any build.prop editing because after this youll get fresh fw without any bugs but you can try the way you mentioned here, it cant harm your phone.
repair is not 100% solution

You can use SUS to 'update' your firmware, however it's more easy and simple by just flashing an FTF file which can be found here

I'm from Italy but I don't find an italian FTF file there. Where can I download it? Or which file should I use?
PS what is SUS?

You can/should use the worldwide FTF file mentioned in the reply above.
I'm from the Netherlands myself and most of West-Europe should simply use the worldwide file.
EDIT
About SUS, it stands for Sony Update Service, it's just like PC Companion but only the updating & repair of Xperia devices. It has no programs to transer files etc.

I have two last question:
From the guide I see I have to put my phone in Flash mode. Is it possible without unlocking my bootloader?
I have my phone rooted. If I flash a firmware with FTF will I lost my root?

1. You don't need to unlock your bootloader to flash FTF files
2. Yes, you'll need to root your phone again

I've flashed EuropeCE firmware via flashtool and Vodafone branding disapeared from my phone, along with a bunch of bloatware.

Yes it is possible. I even flashed E6603 firmware on the E6653 and back to E6653 without issues in operation or connectivity. Also, Xperifirm is working fine here, downloads and all.

do you still have to delete the fwinfo.xml after xperifirm compiles the files prior to flashing with flashtool?

I bundle the files with flashtool so I can't answer that question.

And by installing another firmware, it will void the warranty?

No

If this is really working like you don't loose DRM-Keys and the Bootloader doesn't need to be unlocked.
Why aren't we using this way to get Root into a unlocked Z5? It kinda seems like this is the easiest way in...

Well i do understand it in this way: having Full rights using the SuperSu APK-file with other binarys which are included in the rom.
And Since the ftf-file is the image for the nand of the Xperia Z5 i thougt you can create a ftf file which is prerooted....
:Edit:
And there is the answer for my question...
tl;dr - we can - if we have Sonys private Keys for resigning the system.sin
:Edit:
Tried it to flash Customized CCE1 32.0.A.4.11 for my E6653 and it somehow hang up while flashing TA Partition 1 since then when i try to restart the flashing i get Errors while Processing loader.sin and the Flash aborts with error 7 in processHeader....
i let the flashtool built the ftf file so yeah...
Edit2: Well Sony PC Companion seems to get the Z5 back to life via recovery

XPERIA Z3v Unrooting Issues

So I recently rooted my XPERIA Z3v device, and I have decided to unroot it (don't bother trying to convince me to keep the root, I am far beyond your rhetorical questions) and I rooted with the mobile version of kingoapp.com root. When I attempt to unroot my device, neither the computer software nor the app itself are unable to unroot the device. Honestly, I regret ever rooting, and being the rookie I am, I just want to unroot my device so I can go about normal life.
Can someone please help me? I am on the edge of **** right now.

Flash a stock FTF using flashtool or force a software repair using PCCompanion

Can you provide links for FTF and such? Sorry for the pestering, it's late at night and I just want to go to bed.
PC Companion refuses to acknowledge that the Z3v exists, Sony lacks support for it.

http://www.flashtool.net/index.php
You can download the FTF using flashtool as well.
I am pretty sure PCCompanion provides support for the Z3v

Trust me, the XPERIA Z3v lacks any support from Sony. It is basically the basterd child of the Sony smartphone division. Pc Companion won't work for this, I have tried many times.
As for the FTF, I don't see any D6708 model firmwares there, is my feeble newbie mind missing something?
On another note again, I will be willing to keep the root access, it's just that I attempt to replace the Kinguser SU app, and superSU can't seem to update it's binary to do so. Any help there?

what firmware version are you looking for? LL or LP
Original KK firmware here: http://firmwaremobile.com/index.php/xperiadownload/file/262-z3-v
I can't find the LP leaked firmware. I believe you can download it using xperifirm and create the ftf using the flash tool.

I am looking for firmware 23.0.E.1.44. I found a supposed compatible firmware on Sony's website, but the boot unlocking and flashing seems to be a bit out of my range when it comes to understanding. (Kitkat 4.4.4)

can't unlock the bootloader on the z3v so don't worry about that. You'll have to use the flashtool to flash the KK firmware I linked above then take the OTA to .44

Z5 Generic Rom

Hi guys,
Upgraded from a Z3 to a Z5 this week.
Unfortunately the Z5 is from the Vodafone network and therefore has all their crap bloatware installed.
I've got the phone unlocked to use on o2, and was wondering if there was any way to flash a default marshmallow image on to it?? I'm not bothered about root at the moment, but just want a clean ROM on there.
It's a E6653 Z%
Bootloader unlock allowed is NO
Thanks all

Usually you can use flashtool to flash a FTF file (you can also download via flashtool > XF icon)
I like to download the russian FTFs because they have less bloatware unlike the UK versions
If ye need to know more on flashtool either ask or do some googling

Thanks for your reply. I already have flashtool and adb all set up from before.
Is there a link you can point me to for the Marshmallow ROM??

Flashing Xperia XZP?

Hi, i've sony xperia xz premium and i want to flash a generic italian firmware. It's my first time in flashing a sony device and i searched a lot in internet, but i found nothing. I'm on locked bootloader, any help please?

You need flashtool to flash Sony devices. www.flashtool.net
But, it is not yet compatible with XZP.
There is another tool but no one know the safety of it so better wait.
Btw, you don't need to unlock the bootloader to flash official roms from other regions.

thank you man. I was reading about a file which is needed to use XZP with flashtool.
And, What about Xperia companion, SEUS and Emma? Are them good to de-brand?

Don't know those 2 other tools.
Personnaly I used on old version of that unsafe tool found on another thread here to unbrand, then to sleep well I did a software recovery using official Xperia companion.
Maybe it is total useless but who knows

EDIT: for those who were lookin' for a solution, i used this unsafe tool: i just downloaded custom it firmware from xperiafirm, i pasted all the files (except all .ta files) in the same directory of the tool and i executed it. Now i'm restoring with xperia companion. All good! Thanks

Would there be any advantage with using a generic firmware for the same region, versus the carrier specific one?

So, does unlocking the bootloader and rooting cause you to stop getting OTA updates like on most phones?

I feel your pain. You need newflasher and to follow the tutorial here
https://forum.xda-developers.com/showpost.php?p=72958788&postcount=16
- except make sure you put all the *.sin files in the newflasher directory and flash your phone.. Exclude everything else
The newflasher version that worked for me can be found here

You don't have carrier bloatwares, but most of all, usually custom fw are released sooner because they don't need carriers approvals.

Don't remember about the bootloader but rooting it most probably make it fail to update.
Can't confirm, I usually flash new firm when they are released and don't wait for OTA stuff.
But the most annoying with Xperia phones since Z series, they have a "TA" partition, that contains DRM keys. They are used to unlock features like Bravia engine, special sound processing, ... And it seems also some camera features on XZP.
And when you unlock the bootloader, it wipes this partition and you lose your keys forever.
On Z5 there were two solution for this problem:
- Wait for a security breach that allow rooting Android, and gives you the hability to backup this partition. Then you can restore it after unlocked bootloader.
- Some people modded kernels to fake the presence of DRM keys.
In my opinion, for bootloader unlocking, wait that XZ1 are released (since they probably will have same specs as XZP) and more people getting involved to see what happens. Losing keys = losing Sony specific features you paid for.

By doing this, u won't lose any DRM key: obviously u need to remove all *.ta files (same from boot directory) in which those keys are contained.
I successfully flashed generic firmware over customized carrier firmware and in support app i got the same warranty message. No unlock no drm lost
@Jake_09 yes, carriers are often slowers in releasing firmware (i'm speaking about TIM carrier for Italy), in fact the rom which i found when i bought my phone was updated at april security patches. Now i got the last no brand update. I did the same as @ninjy with xperia companion after newflasher. Hope it helps!

Unlocking bootloader wipe TA partition, not flashing roms

Why we can't use flashtool? Maybe an old flashtool version can be used? I do not trust newflasher since virustotal reports it as a malware https://www.virustotal.com/sr/file/...57fcac8e88f48e8ab00a1cc61c9081d8f47/analysis/

That looks like a false positive since it's only 2-3 different AVs (at most) that are detecting it.
I'm going to flash to an unbranded/generic FW tonight and see how it goes!

Cheers for this. I was worries about losing the features of the sony if I flashed a generic rom over the carrier specific one I have.
Not sure if this will do anything to improve the compatability between my car and the phone via bluetooth but worth a try.

This definitely didn't touch DRM at all. Just make sure you definitely don't use any of the *.TA files at all, even the one in the BOOT folder. I can still adjust my screen colour settings and they definitely work, sound settings, etc. Works great

Whats this talk about excluding .ta files? I just drop newflasher in fw folder and flash, works like a charm everytime.
What benefit do you get for excluding .ta?
