Unlocked bootloader but lost root

And I confirmed it worked like a charm using a model D2303. I indeed flashed the latest build noted 18.3.C.0.37 with PC Companion. Then I followed Sony instructions without hassles.
Beware Towelroot is unable to enforce the previous exploit. The kernel was patched accordingly. Furthermore I could not identify any suitable recovery yet.
Therefore it may be wise to wait a little bit prior to flashing this ROM...
Best regards

Hello, everyone!
My dad has an E3 LTE (D2203) with locked bootloader.
I checked on the Sony dev site, followed all the instructions and unfortunately it says "Allow bootloader unlock: NO" :crying:
My question is if I can use the Flashtool to flash an official ROM without unlocking the bootloader.
I have the official ROM packed as a FTF file and I'm not sure whether it's 100% to proceed with flashing it or not.
I've read on some page that it might soft-brick the device if the BL is locked, EVEN IF the firmware is an official one.
Has anyone tried this already?
Thank you in advance for all your answers/suggestion :good:
It is perfectly safe to flash from Flashtool as long as the ftf is proper and you do it the right way.
@atomicr Thank you but could you please tell me what "do it the right way" implies? Thank you in advance.
Follow procedure in this post till step 7.

Hello here are the new open device bootloader with an seperated recovery partition
and the old bootloader taken from the 18.5.C.0.19 update as FTF files ready to flash with
flashtool.
You can use this if you've accidently flashed the new bootloader over an official Sony ROM
and don't want to loose all your data
D2203:
Open device BL
"Old" 18.5.C.0.19 BL
D2212:
"Old" 18.5.B.0.26 BL
Any way to obtain stock bootloader of 18.5.b.0.26
which country/phone is that?
edit: got it and gonna try it but somebody will have to test it
edit2: please report if it works

Don't use latest Flashtool (0.9.19). Use 0.9.18.6.
hi, first of all, i ve got a D2203 LTE . My bootloader cannot be officially unlocked. If i flash the open devices bootloader, does it mean, i get an unlocked bootloader. If so, what do i do next because i have flashed it and all i get is a black screen. P.S. i am on stock Sony Rom
the new bootloader doesn't work with sony roms,
you have to flash cyanogenmod or aosp.

link for old D2212 bootloader is down, can you re-upload it?
my bootloader is unlock allowed NO(D2203),can i flash this bootloader?
i use 4.4.4 build 18.5.C.0.19
i tryed,black screen
D2212 link update please
No link is working, dev-host links are having issues with downloads and I've lost D2203 open bootloader file
UPDATE:
I've found D2203 new and old BL files in my old laptop, I've reuploaded them to Android File Host.
For D2212 just download stock rom from Xperifirm and flash it to get old BL working.
Link to the folder
These files were originally uploaded by @berni987654321
Is there a way for us to know which partition from /dev/block/platform/msm_sdcc.1/by-name is the bootloader?
So to clarify if I have a DD2203 with sony bootloader that is unlock allowed = NO, so its locked I can flash this and have a fully working unlocked bootloader that I can load cyanogenmod with?

I have the same problem. I think you can't install any firmware without the bootloader unlocked.

you can unlock the bootloader on latest version, you don't need to be on 0.37 firmware.
edit: but if you want to install anyway i uploaded it to my drive:

Thanks very much. I also have a Singapore version of the ROM. On the Sony bootloader unlocking page it says "Important note! In order to unlock your Xperia™ M2 you need to be on software version 18.3.C.0.37". I haven't attempted to go ahead with it anyway.
Do you have drivers that work? I can't get any PC nor FlashTool to recognise the M2! (FlashTool doesn't include M2 drivers.) Do you know how I could install the ROM? I want to do so anyway regardless of unlocking the bootloader because I gather the Android 4.4 ROM is faster than the laggy 5.1.1 one currently installed on my M2.

no problem. if i remember correctly the bootloader unlock page was last updated on late 2014 so that note targeted people who used 4.3 jelly bean at the time. you can unlock bootloader on 0.182.
flashtool includes m2 drivers, you need to install Fastboot and Flashmode drivers. also if you are using Windows 8 and above, you need to disable driver signature check (google it). to install stock roms, this device's forum has plenty of guides. do a little research )
also you don't need to unlock your bootloader to install stock and stock based roms (such as Z5 Style, EagleExperience etc.). if you want to install custom roms (Lineage, RR, etc.) you need to unlock bootloader.

Thanks again for the info. I did install Fastboot and Flashmode drivers as per the tutorial on this site I was following, but FlashTool didn't recognise the M2 on Windows XP nor 7 let alone 10 (I have a lot of old PCs!). I'll try a different USB cable.

oh that's unfortunate, i'll install flashtool today and report back to you. maybe recent versions of flashtool broke compatibility with m2 (if so, i'll also upload the version that is compatible with m2)

Hello friends
Sony Xperia Xz mobile phone I want to make Root authority but I can not find a definite method to make Root.
Please help me find a way to do easy and precise Root.
I know how to unlock the bootloader, but I do not know how to make root.
thank you
Xperia Xz

First of all,if you need to back up your TA keys, you need to downgrade to Marshmallow.
Just unlock the bootloader and flash a modified kernel. Then flash magisk and safety fix.
Alternative metheod: unlock the bootloader and flash existanz custom Rom.you will have root plus tons of added futures
