How to Downgrade XZs Dual to Nouget 7.1 ? - Sony Xperia XZs Questions & Answers

Hello . How can i Downgrade My Xperia XZs Dual 8.0 to Nouget 7.1 ? My device is new and Boot Loader Locked . I don't see FTF of Nouget here . I want to Downgrade becase the Battery is Worse in Oreo also with Heating Issue .

I've been looking for instructions on downgrading my f8131 and i can't find anything that helps. every time i try to flash with the flashtool i get some loader error.

I think it requires Unlocked bootloader

Try using flashtool to download the FTF. However, that may only contain the latest FTFs. You could check on xperiacheck for older FTFs.
You do not need an unlocked bootloader to do this.

Thank You for the response ! Appreciated !

Are you serious we don't need to unlocked the bootloader if we wanted to flash something?

Do you have unlocked bootloader?
then issue is known,
read instruction on sony's bootloader unlock website:
"For customers that have unlocked the boot loader, please do not accept any over the air upgrades."
http://unlockbootloader.sonymobile.com/
Best way is to flash latest version's ftf.

Software version and Bootloader unlocking

Hi, first of all, i want to say sorry for my english if it is bad or if there is an error in my typing.
I have the 18.3.A.0.31 software version on my M2 D2305, wich is the 4.4.2 kitkat, and i wanted to unlock my bootloader, in the sony page for unlocking bootloaders it says that i must be on the 18.3.C.0.37 version of software. Does it mean that i cant use that method ? or my version is newer than the one on the page ?.
Another question is if i need or if it would be recomended by you guys , to download and flash with flashtools a .37 or .40 ftf . should i do it or should i wait to an OTA to come to my phone or unlock the bootloader succesfuly and be able to install cm11 or another rom ? .
Thanks anyway and greetings
In general terms, it means that you must've Android 4.4.2 KitKat version on your Xperia M2 device (regardless if it's a .31 version). Or at least, that's what I understand from SonyMobile website from Bootloader Unlocking.
Regards!

[Q] Flash 5.0.2 on D6603 (unlocked/flashed)

Hi,
i want to update my xperia z3 D6603 to the newest Lollipop 5.0.2 Update.
If I want to do this via PC Companion, but I got an error 2003 that it can't update my phone. I think this is happening because I unlocked the bootloader.
The currently installed version is 4.4.4 (23.0.1.A.5.77). This was installed from a service company, so I don't have any clue how to flash my device to the new lollipop 5.0.2.
Can you tell me what I need for the installation? Is there a complete tutorial for it?
I already downloaded flashtool and found the custom lollipop roms here. Do i just have to go into the flashmode, start the flashtool and flash the new image?
Looking forward to get some help from you
greetings
caelistic
Yes, you're right. Just follow the on screen instructions of flashtool and you should be good to go

root z3 6633

Hi
I have a Sony Xperia Z3 Dual (D6633)
Android Lollipop 6.0.1 Build 23.5.A.0.570 ( Original-Stock firmware )
Locked bootloader
I want to root it without flashing any new firmware, and without unlocking the bootloader
Just Rooting
If someone can make a video explaining, I'm using the translate BR .
thanks
For now, there is no known way to root this firmware w/o unlocking bootloader. Best way to obtain root is to downgrade to KK, get Root and recovery, and then flash pre-rooted MM firmware. Here is very good tutorial for that: http://forum.xda-developers.com/z3/general/guide-rootrecovery-how-to-root-install-t3017056.
Also, I don't recommend to unlock the bootloader. bacause you'll get almoust only downsides.

Flashing New Bootloader using EMMA

Hi
I looked everywhere to get the new bootloader on my Z3 D6653.
I have downloaded Emma and tried to flash the phone but it recognize my phone as D6603 so I thought of not flashing causing the phone to brick.
So I really wanna try 14.1 roms but everywhere it says you need the new bootloader so is there a way to get it.
I am currently on 6.0.1 LinuXRom
Thanks
If you on latest Android 6.0.1 then you only need a latest TWRP 3.1 recovery by @nailyk - https://www.androidfilehost.com/?fid=745425885120716037 and then flash stable Lineage OS 14.1 by @nailyk - https://www.androidfilehost.com/?w=files&flid=164444 . That's all! But if you want to return on 6.0.1 use Emma tool.
