Hi, first of all, i want to say sorry for my english if it is bad or if there is an error in my typing.
I have the 18.3.A.0.31 software version on my M2 D2305, wich is the 4.4.2 kitkat, and i wanted to unlock my bootloader, in the sony page for unlocking bootloaders it says that i must be on the 18.3.C.0.37 version of software. Does it mean that i cant use that method ? or my version is newer than the one on the page ?.
Another question is if i need or if it would be recomended by you guys , to download and flash with flashtools a .37 or .40 ftf . should i do it or should i wait to an OTA to come to my phone or unlock the bootloader succesfuly and be able to install cm11 or another rom ? .
Thanks anyway and greetings
In general terms, it means that you must've Android 4.4.2 KitKat version on your Xperia M2 device (regardless if it's a .31 version). Or at least, that's what I understand from SonyMobile website from Bootloader Unlocking.
Regards!
I would love to achieve root without unlocking the BL. Like it is described in this post for the Z1.
The idea would be to flash the FTF for the (stock) JB kernel with Flashtool, apply Easyroot and then flash back the original kernel. At least on the Z1 it seems to work.
I would be willing to try, I just don't know how to get the FTF with the two kernels. Hopefully this shouldn't delete any data either and the root might stick with any future KitKat OTA updates. Does anyone know how to get a copy of the FTF for the D2303 JB and 18.3.1.C.0.21 kernels?

To get FTF for 2303 JB version, please look at the forum, maybe someone has posting FTF files for 4.3 android version.
For 18.3.1.C.0.21 kernel, you can obtain that from FTF 18.3.1.C.0.21, but only flash kernel. Don't wipe data and exlude anything except Kernel in flashtool while flashing.
Maybe you should try XperiFirm for download FTF files.

Ok, thanks. But all JB links I've found are dead. Still is it actually possible with Flashtool to just flash the kernel(s) from the whole ROM without wiping anything? That would be great.
My issue right now is that I can't find any active link to the JB ROM. Also I nearly finished my monthly Internet traffic quota already. And I don't have a Windows PC either (I use OSX). So if anyone with the ROMs and the right skills could make the kernel only FTFs I would really appreciate it.

Actually i have found one 4.3 FTF firmware. It's for D2303 and i have flashed only jb kernel on 4.4.2 but it's not working. After Sony logo, phone only switches on/off so you can't get to bootanimation even. If you have any idea tell me im going to test it. What we need is patched 4.4.2 kernel which we are going to push su file and then flash our original kernel.
Well my model is D2306, and I did the following:
1 - Flash JB ftf, root with towelroot and install SuperSU from playstore (dont update binary)
2- Update through OTA (Update Center) to KK 4.4.2, and then to 4.4.4.
3- Through flashtool, apply root via towelroot again, after reboot, install SuperSU to /system.
And now I'm rooted with locked BL. Try yourself.

Yea, that's working for D2303 too, but is little boring. So everytime when you going to brick your phone while changing build.prop for example or something like that you have to repeat that process and with this idea (just changing the kernles) could be great because it takes less time and it's easier.

So how does it work? After downgrading to 4.3 it gets two OTAs? I think the trick updating with OTAs works because the OTAs must just do an incremental install. Still i can't afford to do it every time, due to my network cap restriction (I know. It feels like living in Neanderthal).
I've searched in this forum and i haven't found a proper aswer about flashing the 4.4.4 update on the previous 4.4.2 version. I can't autoupdate it since I rooted my phone, so how do I do it? Do I lose the root and need to do it again? Thanks about the 4.4.2 root and if you can help me i'd appreciate that!
Peace!

Just download the respective firmware and flash it via Flashtool.
You won't lose the drm keys.

1. So no problem if 4.4.4 (.93) is rooted?
2. If it's OK. Any chance to root Lollipop like i rooted
.93? (Giefroot method)
Thanks
No you can't root 5.0.2 with that method.
If you want to retain root, the only way is to flash pre-rooted zip via NUT's dual recovery.
I must unlock the bootloader to do that?
No you do not.
But you must ask questions in the question and answer section.

You need to flash the ftf.. AFAIK the update centre updates do not work after bootloader unlock or something..

Yes, this is true, after unlocking bootloader Sony Update Center complains about "modified software". You need the ftf (search on xda for xperia l ftf 15.3.a.1.17)
