Hello, I just got this phone SO-01J in docomo version which is installed with Android 7, but I found it not running really smoothly. I wonder if downgrading to 6.0 will be better. And I checked that it's NOT ALLOWED in bootloader unlock. So can I do this ? If so , which firmware I should choose to download?
I found an article shows an valid downgrade with F8331, it uses Xperia Flashtool and Xperia Companion. does this method also apply for SO-01J? If not, what's the proper way of doing so?
Many thanks.
What do you mean by it's not smooth? You're getting lags in gaming? Or the whole os is lagging? If the whole os is lagging then i think you should do a software repair with Xperia Companion... By the way... This phone can be updated to oreo

Thanks for replying! The whole os is quite lagging, even when I'm only running normal apps such as dialing, messages, camera and browser. Sometimes such experience just really annoys me.
And it has many Japanese Apps which are I hardly use and I want to get rid of them. So I'd like to get a downgrade to see if 6.0 would be better.
It wouldn't give a big changes tho....Android 7 shouldn't be lagging on your phone... About the mm firmware... Download flashtool and open xperifirm(something like that) and choose any mm firmware for SO-01J.. And flash it using the flashtoo.. lhttps://www.teamandroid.com/2017/04/11/downgrade-xperia-xz-android-601-marshmallow-firmware/ <---- tutorial about how to flash firmware using FlashTool...
I'm not responsible if you bricked your device while doing this process

Thanks, but it seems that in XperiFirm for SO-01J there is only the latest updated firmware available. (39.2.B.0.336) I don't know if I can use other versions' firmwares, such as F8331, F8332 for my SO-01J.
I'm not really sure because I'm not very good in firmwares...But try to give a software repair(software repair from Xperia Companion) a try... Because it shouldn't lag on your phone so something is wrong with your os... Software repair may fix your problem.. By the way.. Is there any option for you to update to oreo on your XZ?

Any way to downgrade to Kitkat 4.4.4?
Thanks
Mod Edit:
Thread closed at OPs request.
You can downgrde by using Flashtool by @Androxyde and flash 4.4.4 ftf for your model but you will loose your data because of lollipop ART. If you need a ftf i can upload one for you

Thanks. I'm not going to flash it right now, but I'll need latest version of Kitkat available for D2302. I'll get my hands on a PC in a week, then I'll flash the phone.
I have one question though.
After downgrading through flashtool, will my phone be able to recieve OTA? (in case they decide to release fix for camera) Or will I have to flash again for update?
And I saw that some people were saying they had good camera after lollipop, May I know what did they do?

Yes, after downgrading you will be able to OTA upgrade to lollipop but I think OTA won't work if you have an unlocked bootloader. And i don't know how people with a good camera quality have do this.

Thanks! I have an unlocked bootloader. I'll definitely flash Kitkat now.
Hi,
Could anyone please upload latest stock Kitkat 4.4.4 ftf for D2302 India?
Is there any difference between different countries ftf? Like FM frequency, etc.
And one last question, Can I flash stock Sony ftf with Locked Bootloader? And will it still be able to get official updates?
Thanks
Hello everyone! Seems we're going to get root soon on locked bootloader in lollipop, so we can backup the TA partition before unlocking. The question is, can we downgrade from MM to LP without unlocking the bootloader?
You know how google, do you? You can, download the Firmware and flash it via Flashtool.

Yes, I did google. Saw a couple of post about the Z5P, but I'm comming from motorola and they are a little bit special when it comes to downgrade, because of the bootloader. So I want to be sure because I have almost zero exprecience with sony.
Anyway, no need to be rude. Thanks!
You can downgrade with no problems bootloader locked or not as the above poster said flashtool and xperifirm is your friend. I don't have access to links atm

I'm new to this forum so please forgive me. When I bought my Z5 from Vodafone UK, it was running Lollipop 5.1.1 and ran all the apps I wanted flawlessly. Since the update to Marshmallow, ACR and NetVu ObserVer now do not, the developer of ACR cannot work around this so I need to back date the firmware. I have downloaded XperiFirm and Flashtool but can only find 32.0.A.6.200 for EE. I would have preferred the stock Vodafone firmware, but will the EE one do?
any firmware will do as long as those apps work. some branded firmwares have differnt splash screens. thats pretty much the only difference
Thanks for your reply, I'm not bothered about any splash screen but something I noticed is a file named simlock. As EE lock their phones to their network only I take it this file needs omitting?
Regards, John.
Hey, this is my first post and I'm inexperienced with Android tinkering so I apologize if I've broken any rules. I searched but would like clarification as Nougat has changed things.
Is there any way to enable the fingerprint reader after the Nougat OTA for the US version of the XZ F8331?
I mistakenly didn't realize Nougat had changed things and unwittingly soft bricked my XZ the other day but managed to unbrick it and really want to avoid bricking it again.
It seems that downgrading to Marshmallow via flashtool is possible? so maybe it could be possible to downgrade to the UK Marshmallow and then get the UK Nougat OTA and then get the fingerprint reader to function that way?
Any rom you use that isn't the US rom will allow fingerprint to work.
Right, but flashtool isn't compatible with Nougat yet. I just got the idea of using Emma though, will look into it more soon
Yeah, you can just flash an MM rom and update to Nougat via OTA.
EMMA will only work with devices with unlocked bootloaders.
You are correct in your first thought. Just flash a UK FTF for MM and get the OTA Nougat update.
Thanks for the replies. Unfortunately the Customized UK MM FTF seems to be no longer available from XperiFirm and I haven't had any luck trying to find it elsewhere.
How much does the Market/Operator matter? Maybe a customized MM FTF from another region is better? Anything I should be worried about?

Not really. Only a bit of bloatware, everything else is about the same.
You may be able to find an older FTF from here though
Thanks again! There is a Customized UK FTF for MM on the site you linked but it can't be downloaded for free unfortunately.

I am wondering the same - new F8331 on N OTA and enabling the fingerprint reader. Any luck on your end figuring this out?
I've been running customized NOBA in my Z5 for a while here in the US and have been very happy with it. Customized NOBA for the XZ still hasn't been updated to Nougat, so that could be an option. I don't get to unwrap my XZ until Christmas, so I've already downloaded the MM version currently on Xperifirm to re-enable my fingerprint sensor first.
I like customized NOBA because it has bloatware you can completely uninstall.
You should be able to google the central europe firmware (marshmallow) and use that. I just fixed 2 XZs yesterday after banging my head against the wall over the firmware.
Update to marshmallow using flashtool and then OTA update to nougat. Central Europe works perfectly and I get the LTE symbol (some people hated the 4G symbol even though it's the same). Finger print scanner works (both phones are US versions from Amazon).
Help me please

Hey there,
I own a Sony Xperia Z3 D6653 (1288-4394 variant), and it looks like Sony forgot to release the 23.5.A.1.291 firmware update for this variant, which is kind of a bummer since they don't answer my emails.
My phone isn't rooted, and I was wondering if there's a way I can update my firmware without wiping my phone clean.
Thanks!
I own a D6605 with that firmware through OTA update.
Have you searched/selected the correct model at the Sony Support site?
I would recommend to look for it, and maybe specify my model number, and download it yourself.
At the supportsite theres also a tool which has to option to install this update (flash) without wiping your phone. Search this forum for details, as i'm writing this down from memory. They used this method on Z(1) and Z2 before.

What's so special about that TW build? Bands?
Any of the other .291 don't match: https://xpericheck.com/device/D6653 ?
I'd like to ask
does anyone on this forum ever trying to flashing Xperia XZs firmware on XZ?
is it can be true?
if its failed, what gonna happen to the phone?
hope you guys can answer it
thank you
Even Dual SIM version do not work properly, XZs firmware won't work at all. They seem like same phones, but their RAM capacity, camera (and probably eMMC/UFS) are different. So, if you wanna make your phone brick do it
