Hey, I was wondering if it's possible to install custom Roms to the arc s without unlocking the bootloader? It's not that I don't want to unlock the bootloader it's because I can't (checked in the service menu) if it's possible please could you supply some links on how to do it? Thanks

Yes it is.
You can use SE Extreme Tweaker to get custom recovery. From where you can flash ROM. There has got to be a ROM configured to work with stock kernel though.
Then you can flash ROM. But for using custom kernels, you would need an unlocked boot loader.
Highly recommend to do it, since custom kernels like DoomKernel and like (Especially doom-kernel) boost performance.

Thank you for the quick reply! I have rooted and unlocked a bootloader of an x8 and know the advantages of a custom kernel over a stock kernel but, when I tried to unlock the bootloader of the arc s I had to check the service menu to see if I can. It said I could not unlock it so I only have this option

You can unlock your BL using the testpoint method.
You could ask e.g Jinx13 for that.
And post in the correct section.

It's a question, so obviously it goes into Q&A section.
And btw, if you flash a ROM to a locked BL, look to it that it's for locked BLs.
Afaik, there's only one ROM (Aniking's ROM), which can be flashed by both (unlocked & locked).
I will have a look into unlocking my bootloader using the testpoint method, thanks for your replys. Very helpful xD

I'm on ihackers 2.1 ROM android 4.3
rooted
unlocked bootloader
I wanted to go back to stock to C6902_14.2.A.0.290
I found the method but I'm not sure if this is the right way http://lionking853.blogspot.co.uk/2013/11/how-to-go-back-to-stock-firmware-on.html
and if it is the right way, after going back to stock ROM, will my phone unroot and relock again?
Can I just go ahead and do this or must I relock bootloader first?
please help me since I never done this before, only rooted and unlock that I did.
Thank you so much folks
Restore your TA backup.
That will relock your bootloader, of course.
Then just flash official ftf (you have almost all region here on XDA to download).
Flash 136, don't go to 534.
But remember : flashing ftf through flashtool will wipe everything.(and it should)
So backup all your files.
If you want this only for updating to 136, as I can see, many guys just flashed NUT stock deodexed 136 without wiping anything and it's working.

Well it depends on what you want to do! If you want to keep root on stock rom follow this guide
http://forum.xda-developers.com/showthread.php?t=2572988
And if you just want to move back to stock rom, unroot and relock your bootloader, use flashtool to relock your bootloader and flash stock ftf of your choice from here

1. dont flash the latest 4.3 yet
2. downgrade to 4.2 and root using doomlord method or root by bin4ry method
3. once rooted, backup TA partition
4. flash latest 4.3 via sus, pcc, or ftf
5. unlock bootloader
6. flash custom kernel with recovery
7. boot to recovery, flash supersu update zip
8. reflash original 4.3 kernel
9. restore backup TA
10. enjoy 4.3, root, locked bootloader with intact drm keys!

It would be the same...
However you can also flash Doomlord's 4.3 kernel, then boot to recovery and flash the super su zip for root. The kernel from the leaked 4.3 rom seems to be the same as the kernel from the latest update.
Recovery is lost after going back to stock kernel. Root works.
The root works but Mobile Bravia Engine 2 still lost.

Hi guys!
Im trying this method now but I dont have stock 4.3 kernel. Anyone has it? Upload please coz Im stuck now
To Flash only the kernel from the new rom,
In the flashing options, exclude all (right box) except Kernel.

Yes, root works like a charm but you need to unlock bootloader and flash advanced stock kernel from .256 leak cuz it have recovery and flash the file from attachment, then you must revert to stock kernel and lock bootloader. Voila!

I can't unlock bootloader Orange locks bootloader and anyone can unlock. Then I am looking for method without unlocked BL. And I want to flash kernel from JB 1.257, root and reflash kernel from 4.3. But I'm not sure it is safe.

please don't try that !! it's not possible to use 4.1.2 kernel on 4.3 , it may brick your device .
Ok, thanks, bro. So I must wait for root for locked bl ;C

Hi, I just root 266 by unlocking bootloader, flashing Advance Kernel and updating SuperSu via CWM, now the question is should I flash the 266 stock kernel? and why?
Thanks
Does anyone think it would be possible to flash the Xperia Z3 firmware on a Z5 only to root it. then install Z5 firmware via TRWP prerooted.
I wondering if the phone would boot up or become a brick.... thoughts ?
Impossible

Impossible dude.. Don't ever think about it even in ur dreams..
Every sony models have different firmwares.. We can't use them..
Just wait for some more times until some one will find a root kit for locked bootloaders...
Different hardware -> different drivers -> different kernel.
if you try it... its possible that you get a hardbrick...
twrp 3.0
TWRP 3.0 is out.
https://twrp.me/
TWRP 3.0 is out alright but the Z5 isn't on the list of supported devices? I've seen screenshots on here of v2.8.7.0 and v3.0.0.0 - how does that work?!
https://twrp.me/Devices/
Z3 firmware can be installed on z5.
But your phone boot and cant enter to home.
Randomly reboot.
If anyone can install rooted z3 firmware for unlocked bootloader, please try.
Not any root program can detect phone .
Why not other approach? Find which part is the app with vulnerable exploit and create a Z5 rom including it to root it?

If we can create pre-rooted Z5 stock rom and flashable via flash tool, i doubt it will boot, as stock kernel don't allows that, so again, unlock bootloader to flash custom kernel. And earth is round. ????

Hello,
So, it's not even remotely possible to flash a different kernel with the the bootloader locked?

Pre rooted stock roms can't flash via flashtool buddy. U need recovery for flashing pre rooted rom..
i have to say only one thing
Please wait and do not do something silly with your device, I am sure by the time pass there should be a way to root with locked boatloader.

My locked bootloader Z1 was plenty happy to boot a stock kernel with a pre-rooted ROM. But, as @Rajeev said, you need a custom recovery to flash pre-rooted zips. Since we have no LB root exploit for the Z5 yet, pre-root still isn't an option.
How about flashing a Z3+/Z4 ROM/Kernel on a locked bootloader. It's the same CPU (810) so you might be something. If you can at least get ADB going, you might be able to exploit it and dump the TA partition.

I'm pretty sure you can as long as they're Sony signed binaries. I'm not sure if the signatures would be compatible though.
An example of picking and choosing parts of the firmware can be seen here: http://forum.xda-developers.com/xperia-z5/general/e6653-flash-e6603-firmware-enable-t3307158

You can with flashtool but you will brick ur phone if the kernel is not meant for your phone.

Are you sure? One of the protections of a locked the bootloader is to make it impossible to brick.

Don't need to be sure but flashing ur phone is always risky if your using other phone's firmware.
If you want you can try and let us know.

Is it possible to relock bootloader when you're currently using custom rom?im thinking of relocking it to avoid random freezes :x

After relocking your phone wont boot in custom rom (btw if you want to use custom rom with stock kernel use stock based roms)
Only stock-based or AOSP 5.0.2 ROMs can be used with bootloader locked.
