[Q] Prerooted image without unlocked bootloader?

Is it posible to flash a prerooted official image with digital signature (if that exists) without having the bootloader unlocked?
my problem is that i can't unlock my bootloader because of my phone company, but i recently flashed the new ICS to my phone and it worked perfectly. this wasnt a problem apparently because it was signed by sony or something and the bootloader didn't complain. so, does there exist a rooted but official image i can flash without unlocking the bootloader?
Thank you all in advance. im really frustrated by not being able to root my device :crying:
hope somebody can help.

[Q] EU generic firmware?

Hello, I just bought a Z2 (D6503) that is never locked (SIM free), boot loader unlocked allowed YES but it has Vodafone firmware on it (Germany). Where do I get an EU generic firmware and how do I flash it?
Unfortunately Z2 is just released and there aren't any tutorials so that's why I'm asking you. Can I take the files from this thread: http://forum.xda-developers.com/showthread.php?t=2666849 and use this tool: http://www.flashtool.net/download.php to do it? Do I need to unlock the boot loader first? I would rather not do it if possible (yet).
Thank you.

Flash a stock rom if it's simlocked ?

Hello,
Can I flash a Sony stock rom if my Xperia Z2 is simlocked ?
Best regards
Remove Sim and factory reset first just to be safe is what I would do. But just to be clear, Sim for network and MEID or do you mean the SD ?

Hello,
It's simlocked for Virgin, I would flash the sony stock 5.1.1 Android version.
Have I to unsimlock the the Z2 before flashing ?
Best regards

No you don't need to unlock your sim to flash roms. My phone is locked to vodafone and i've flashed a bunch of roms without any problem.
Just remember that simlocked phones usually have an unlockable bootloader, so you have to use stock based roms.
Thank you,
It's done,

Xperia M4 Aqua Stock Flash and Recovery

Hello guys!
I have a Sony Xperia M4 Aqua E2303 from Orange with their custom firmware.(Their Apps and start-up logo, etc.)
It is possible to flash the sony stock firmware(marshmallow) to get rid of this custom firmware ?
Also after flashing the stock it is possible to install a custom recovery like TWRP?
If is possible to do those operations ,is there a way to back up the actual firmware in case of possible problems?
Im kinda new to this forum but i want to thanks in advance for your help and advices .
Thanks again and have a good one !
If you bought it from Orange, check that your booloader is unlockable (to do this, type this in the call menu: *#*#7378423#*#* then in Services info, rooting status you can see it)
If it's unlockable, you can flash recovery and root it after you unlock the bootloader (You will lose your DRM keys)
Here is a guide about rooting and unlocking.
With root, you can also remove those apps that you want.
(the guide is made for E2353, idk if the files will work for you...)
Also, here you can find the stock roms.

Thanks for your help buddy.
Unfortunately the bootloader is not unlockable.
But i took the risk and i flashed a stock firmware (E2303,Central Europe 1, 6.0.1) via Flashtool and XperiFirm. I got rid of all orange apps except one which is good ,my free space is around 4gb from those 8gb. Also the phone is more faster in menus and some apps.
I saw a thread here on xda , about rooting and flashing recovery with locked bootloader but need to downgrade to lollipop Here. I do not not know if it is worth the while.
Is there any way to unlock the bootloader even if it says that it can not ? Maybe Sony Support?
Thanks again ! Good Day !
Your welcome, also i sad to hear, that you can't unlock your bootloader Have a nice day
