[Q] How install Generic D2306 Firmware

Hello again D:<
Another question (u_u. I've never had a Xperia smartphone before, so :c).
I don't know about how install the Generic Xperia M2 4.4.2 Firmware, well, I know something, like use Flashtool for mount the FTF file into the phone. But, about the TA Backup?.
I'm kinda unpredictable, so, summarizing everything... Could you please give a tutorial about those steps that I must follow to install the 4.4.2 Generic Firmware for Xperia D2306?
Thanks for everything.
Regards!

Thanks, so, I suppose will work fine the TA Backup from that link. I'll check it.
But, my Info Service from Bootloader allow or not says this: "Bootloader unlock allowed: No", so basing on that assumption, I don't think that Bootloader can be unlocked. So, I have the question about is it extremely necessary has the bootloader unlocked for flash the 4.4.2 Generic KitKat D2306 Model with Flashtool :c.
Thanks

You can flash ftf with locked bootloader.

But be careful, they only did kernel to D2303/D2305.

But, the kernel is only used for people who use ClockWorkMod Recovery for install ROM or Root with Unlocked Bootloader. I don't try to install ROM (CyanogenMod, that is based on D2303 model), neither Root with Unlocked Bootloader ('Cause I can't unlock bootloader). I'm gonna use Flashtool, and other comments says nothing about Kernel and ClockWorkMod Recovery.
Thanks either way :3.

how do I relock bootloader?

I got an update on my Xperia M2(d2305) to 4.4.4. I rooted my phone when it was 4.4.2. When I try to update it, it shows an error where it says (Sony update engine failure error 2003). I unroot my phones using the factory data reset but still with the same error. When I checked the bootloader it still say YES. .how do i lock back?

You got an update on your Xperia M2(d2305) to 4.4.4.So you didnt unlock the bootloader. Right?
First when you root your phone that makes a file name su in your system.Factory data doesnt change system folders.So you have still root access.
All you need to do is;
-install supersu
-Get into setings
-Click unroot botton That remove your root access.
i am not sure but if you instaled xposed you may need to remove it.You can find it in firmware options.
(Just in case: to relock the bootloader Connect your phone (into flash mode) to Flashtool and click the "BLU" button )
Good Luck

@XlseS
Did you try to relock it with Flashtool? There was option for that i did it on my Tipo.

Device does not boot after I did that.

Are you on stock rom?

JUST DOWNLOAD FLASHTOOL AND YOU'RE DONE!: HERE
1 boot into fastboot
2 head over ur computa and click relock, easy enough ? :silly:

I had an update to 4.4.2 via PC Companion, so files are all there.
If I reflash my phone, will the TA partition get reflashed too? In other words, will it get back my DRM keys?
There is method with TA script to backup and restore TA, but if I have backup of original ROM that came with my phone, so I'm asking will it do the job, because I have TA.img without md5sum.
Another reason is this one: http://www.xda-developers.com/restore-lost-functionality-on-your-unlocked-xperia-device-part-two/
Camera seems to get loss of functionality with removal of DRM keys.
EDIT: The answer is: nope. TA partition must be restored first.

[FTF][Bootloader]Open device and 18.5.C.0.19[D2203]

Hello here are the new open device bootloader with an seperated recovery partition

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

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?

Update stock firmware with custom recovery

so after giving up on installing cm12 I've decided to roll back to the stock sony firmware
but, I kinda downloaded a version that is a little bit outdated, so I have to update it
the problem is, when the cellphone goes to install it, it just boots on twrp
is there any way to fix that?

Are you trying to install a .zip file or a .ftf file?
.ftf files are only flashable with flashtool via a pc.

Use flashtool to download the latest FTF file and flash that

How were you going to install cm then? That needs an unlocked boot.
You can still use flash tool to repair your phone though.

For the third time
Use flashtool to download the latest FTF for your device and flash it.
Or, if you can access recovery just flash a pre-rooted .zip for your device

Can't flash 7.0

I got a unlocked bootloader XZ dual 8332, download tft from Xperiafirm, and at the end of flash session i got a erro :
Code:
[COLOR="Red"]01/025/2016 17:25:54 - ERROR - Have read only 524256 byte(s) instead of 780004 byte(s)
01/025/2016 17:25:54 - ERROR - Error flashing. Aborted[/COLOR]
What does it's meanning ? My phone got a "update failed" when turn on now.
Do we need check some "check box" or anything before flash a tft file ?
And is anyway to relock bootloader if we want repair by Xperia Companion or update through OTA ?
Thanks.

AFAIK flashtool is not compatible with 7.0 yet and there is no way to relock your bootloader yet.

When you flash a modified kernel with drm fix your drm is working. When you relock your bootloader your phone got factory reset itself and drm still in your phone.
Try to update via ota
After that because you are unlocked try to flash flashfire and install supersu to be rooted and searsh to drm fix file and flash it manually from any root file manager.
Another step
Uodate your unlocked phone ota update
Restart you phone
It should be working now with no drm fix
Poweroff your phone
Enter falshmode (power button + volum up) you see a purpul led
Enter adb and flash supersu sr5
It should work after flash drm manually
Try and reply please

So much wrong info here.
Firstly, once you unlock the bootloader the TA partition where the DRM keys are stored is formatted. They are gone forever. Relocking the bootloader does not bring them back. The DRM fix replicates (Not 100% fixes) the missing functions and this fix only works on rooted phones, which you cannot have with a locked bootloader.
Secondly, do not try and update OTA with an unlocked bootloader. It could brick your device.
Are there any known issues when unlocking the boot loader?
A: Yes. When you select a device, any known issues for that device will be displayed. In addition, the following generic issues have been reported:
•Some users have experienced problems when they are accepting over the air upgrades. Therefore we do not recommend users to accept over the air upgrades, after having unlocked the boot loader. For additional information, check out the XDA Forums for hints and tips from the community.

Xperia companion will fail. It will detect unlocked bootloader and not work.
OTA 'may' work, but as I said and quoted it 'may' also brick your device. Do it at your own risk.

Everything you wrote is absolutely correct.
PC companion detects that the device is unlocked & OTA's automatically fails to install.
So apparently, relocking & updating is possible but relocking means you can no longer use the stock camera anymore.
