Flashing latest Firmware on Z3 Dual D6633 - Xperia Z3 Q&A, Help & Troubleshooting

Hello,
Ok so I successfully rooted and installed TWRP on my Z3 Dual D6633. I had to downgrade to 23.0.F.1.74. I believe my bootloader is still locked. Can I just download the latest firmware from XperiFirm and flash it with flashtool to update to MM?
Thanks

If your bootloader is unlocked, you can't update via OTA.
You'll need tui flash ftf via flashtool once it's available on Sony servers updates don't work once rooted or your bootloader is unlocked

(?) Root Z3 Dual D6633 Android 6.0.1 with OneClickRoot?

hi Everyone!
I have stock D6633 Dual sim run MM6.0.1 (LB). Could i use OneClickRoot to root it? thank you

I don't think you can root your phone directly from marshmallow
You have to downgrade to an older firmware, root your phone and install recovery, then flash a pre-rooted marshmallow rom
you can follow this guide

How to Downgrade XZs Dual to Nouget 7.1 ?

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?

Xperia Z3 D6603 Reboot repeatedly after flashing rom

Hi,
I tried to root my Xperia Z3 D6603 with flashtool. I downloaded the Global firmware version 23.0.A.2.93 since my bootloader is locked to root my device. Once flashed, my device boot normally, but it says contacts has stopped and then reboot over and over again. My phone is the Canadian version and i'm wondering if there is something to troubleshoot my problem.
Thank you very much
Michel
download the different stock rom and flash it again
