Downgrade E6653 from MM to LP? - Xperia Z5 Q&A, Help & Troubleshooting

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.

UK 3 network splash screen

Hey, I'm from UK and got my Z3 yesterday. Lovely phone, however I'm stuck with the ugly 3 splash screen upon boot. Is there any way to get rid of this? Is there another firmware I can flash which will work with my phone? Thanks for your help.
Go in the the general section and there is a sticky thread (at the top) all you have to do is use flashtool and flash one of the unbranded firmwares for your model. This is what I did with my O2 phone. Hope this helps

Hi thanks mate. Brilliant we haven't got to unlock bootloader or be rooted. Do I flash the UK generic ftf file? Does generic refer to network unbranded? Kind regards.

I'm a different mate , but yes, "generic" means "unbranded". To be more specific, flash "Customized UK 23.0.A.2.105 / R9B" and you have the latest without any carrier branding.

Just to confirm, I won't lose my DRM keys, and the camera won't be affected if I flash an FTF file? This only occurs if I root/unlock bootloader, correct? Thanks very much for help

D6603 from Sony Store in US no Lollipop

I have a D6603 from the Sony Store running on AT&T. I still haven't received the Lollipop update OTA, or on Sony Companion. I don't want to push it through from XperiaFirmware, as I'm scared to brick it. Any reason why the OTA still hasn't come over?

Usually the service providers are slow to push updates, sometimes not at all. I am sure your device shall get the OTA but it would take a bit more time. Stay patient.
If you wish to flash Lollipop now, I suggest you do it with a flashtool. However, make sure you use device specific FTF or you will brick your phone.

The Z3 is unlocked from the Sony Store. AT&T doesn't even offer the phone so it shouldn't have to go through AT&T for them to push the update.

Before I can answer further, I need more details.
Are you rooted or on unlocked bootloader
What is your device's model number ?

Odd, I have every z3 variant from Sony.com ver to Japan docomo ver and other than the dual sim model, all are on most current 5.0 now...maybe try removing the sim and attempt update notice via wifi only?
I update all of mine with no sim.

Do you have to leave the SIM card out for a long period of time? I left it out for an hour or so, no update, and tried connecting to Sony Companion with no SIM and still nothing.

Help for Downgrading to Kitkat

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

Newbie - debranding Z5

Hi everyone
I have just purchased my first Sony phone, the Z5.
It is on Vodafone UK but has been officially unlocked. I wish to debrand and put on stock Sony android software so remove the network branding. Can someone pleas ehlpe as I have never done this before. I have just downloaded flashtool.
My second question - If I use flashtool to change to stock software, will I still receive OTA updates for future software updates rather than having to use flashtool all the time?
Thanks in advance.
Yes, with official firmware everything will be fine.

Hi to all, sorry if I port afloat this old thread.
I have a Z5 with a MM branded firmware (TIM Italy). I already know how to debrand it flashing another compatible firmware.
My question is: is it necessary wipe all data, also if I flash another MM firmware?
By what I read, I understood that if I stay on the same major update (in this case MM) I shouldn't meet any kind of problem also if I didn't wipe all. Is it right?
Thanks to all

Xperia XZ F8331 - Is it possible to enable the fingerprint reader after Nougat OTA?

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
