[Q] [CM] Install CM without unlocking bootloader

Hello all,
I have a question regarding my Xperia Z.
I would like to install Cyanogenmod 10.1 (Stable) for my Xperia Z but I do see some various kinds of methods.
1. By using fastboot (Don't know exactely what it does).
2. By using a custom recovery.
Now, my phone is rooted and I do have a custom recovery.
Can I flash Cyanogenmod without unlocking my bootloader? (I don't want to loose Bravia engine and Stamina mode) when I ever decide to go back to stock.
From what I understand, fastboot will flash the CM kernel (not possible with a locked bootloader) while the custom recovery only installs a rom without a kernel.
Does it mean that I will have the stock kernel but with CM rom on it?
A couple of questions comes to mind in total:
- Can I flash CM using custom recovery?
- How to return to stock rom if ever needed (Will i loose my Bravia Engine -> DRM keys)?
- How to update the kernel to a new stock kernel if needed while running CM?
Kind regards,

You can't. You need to unlock your bootloader in order to flash the cm kernel.

But that does mean that I'll loose my DRM keys forever?
I don't want to lose them just in case I need to restore.
And if I unlock my bootloader, how do I exactely flash CM?
Kind regards

Before unlocking, you can save your DRM keys with this method.

Correct me if I'm wrong, but is the process then the following:
1. Root phone without unlocking bootloader.
2. Install CMW
3. Backup DRM keys.
4. Take Nandroid backup.
5. Save the files of the backups (3 & 4) in a safe location.
6. Unlock bootloader.
7. Flash CM.
For a restore:
1. Reflash stock rom.
2. Restore nandroid backup.
3. Restore backup of DRM keys.
Can you confirm that this process is correct, because I really want to install CM.
Is there a list somewhere (cannot find it on the official CM website) that lists me what kind of bugs there are in a specific CM version (what is not working)?
Kind regards,

Correct me if I'm wrong but weren't at least AOKP and ParanoidAndroid developed for locked bootloaders on other phones? If so, technically it should be possible with our Z, right?

I doubt it, but if they were they won't have been a true port.

Honestly, i don't understand the DRM thing. It's not like you lose important features. If you can unlock your bootloader, then do it. Not doing it would be like buying a Ferrari just for your Garage.

Just because they're not important to you doesn't mean they're not to others, and even if I could unlock I'd probably still be holding off in the hope that someone comes up with an S1Tool that allows Sim and Bootloader unlocking for late 2012, 2013 Xperias.

And is there anymore that knows where you can see what kind of things that does not work on CM for the Xperia Z.
I would like to have full funcionality like Radio, NFC, ...
Kind regards,

mate, unless someone finds an exploit, you CANNOT have non stock based roms on a locked bootloader.

There are only 2 bugs that I know of: the screen takes 1.5 seconds to wake up after pressing the power button, loudspeaker in calls doesn't work.
I've also heard that hdmi out is broken but I haven't tried.
I'm running Cyanogenmod personally and it's great.

Hello,
Can you tell me what the difference is between the official Get.cm repo and the freeXperia project.
After that I can install my version of CM.
Thanks for clearing this out.

No real difference. FXP builds are released weekly while official builds are obviously released daily. The same code gets pushed to both builds afaik

It would be nice to be able to use my SD card...

Would love to see a wifi only version too! I will just about cream my pants if I can run CM on this thing. It kicks ass as is, but CM would take it over the edge. So glad I sold my Note 2014 edition for this tablet!

What would be better with CM? I don't see how it could top the stock ROM.

Just my preference. Nothing wrong with stock as I said, it will push it over the edge

Which feaures of CM are causing you to personally prefer it over stock?

Great news! Will play with this, this evening. Some bugs does mean that some things like sound/lte does not work?! Or that only some apps can crash?
Edit: Installed it now on my tablet. For just a preview this is really a great ROM. Had a small bugs on the keyboard for SIM pin but the ROM works fine.

For me the stock rom is quite laggy, it's not a bad ROM by any stretch but certainly not how I like my devices to be setup function

I tried extracting the boot.img from the FXP327 castor_windy zip and it will not
boot to the shared CWM recovery to install the ROM zip.
The filesize for castor_windy is also only 144MB while the rest of the ROMS
for other devices are in the 244MB range.
Has anyone got this to work on the Z2 tablet wifi only?

@adfad666, @jerpelea, can you please confirm this?
Did you use sonyxperiadev/kernel-copyleft or sonyxperiadev/kernel on Github? Or something else?

@Olivier
The kernel used in the aosp build is a prebuilt one.
But there are aosp builds outside of xda booting on a tweaked stock kk kernel.
So the stock kernel definitly boots on aosp.

I know, and that's why I asked I still want a confirmation from jerpelea or adfad666.
BTW, you can flash any kernel on any ROM and it will "boot", the problems are mostly the ramdisk or some configs (e.g. prima).

Ok, lets wait for @jerpelea s answer .
All i know is that the command line to assemble the ramdisk slightly differs from stock and cm, as i've build an aosp kernel some months ago.

kernel is prebuilt on aosp and is built from our source
if you build kernel with android from source you just waste time on build
kernel is rarely updated and is just a waste of time to recompile it every time
this kernel version is not in sync with official releases and updating kernel will break blobs, use provided kernel !
you can build yourself kernel binary and wlan module and then place them into aosp tree

I wonder what voodoo magic did sony did the rom seems way faster then cm11 ?
is the blobs and kernel based on .283 ? @jerpelea

Good news! We now have the official CM12.1 ROM available for the Sony Xperia SP! What are your thoughts? Will you use it? I know I will be!

Very exciting!!!!!!!!!!!
Are you using the official CM12.1?

Kinda surprising, thinking the team may have abandoned XSP as it is a bit "dated".
Anyone tried it yet?

we had it for maybe two months or even more, idk. I prefer stock because of fully working illumination bar, btw.

Read a few complaints that CM12 official is unstable...(??)
[Think it was scattered amongst the consolidated thread on UBL roms (temasek, aicp, etc) by theavengingtitan]

Been using it for a week now. No issues no lagging.. Fast.. Easy on battery.. All apps work. Its a keeper...(had just about given up on lollypop) not now
Sent from never never land.......

Dirty flashed OTA and now it lags. I guess every update should be a clean flash and that sucks, because all apps need to be settled up over and over again.

Well, mine lagged out after installation from option and my gapps is error. Then I flash the gapss but my root access was gone? So, how to root it? Because towel root can't do this. After all it works very smooth.

Are you all using stock cyanogen recovery or philz twrp ?
Sent from never never land

Nightly from today and yesterday is already optimized. You can use, no lag

no SUPERUSER in xperia sp CM12.1
there is no superuser mode built-in in it..

Xperia Z2 CM 13.0 Unofficial

I was googling and I found this link
https://builds.hubdroid.com/cm13/sirius/
There's an unofficial build of CM 13.0 dated 20151212 for sirius on this website, I haven't made or tested this rom, just sharing it for those interested because I've seen people talking about cyanogenmod 13.0 made for the xperia z2 but not out to public, so is this one?

Better than if you test this build

I'd test it after I finish testing the cm 12.1 on my device because it has some weird issue of randomly rebooting on it's own but when im done with that I'd definitely test this
One thing I'm almost sure about is that this rom can't have a working camera since the camera blobs aren't even fully working yet so I wouldn't judge the rom for not having a working camera, if it doesn't
I'm gonna test it but i thought i'd share it so that if anyone that actually heard about this website (cuz I honestly haven't heard about it until now) and could fill in some info about it

It won't boot up

Hello everyone
Rom installation failed,something wrong with updater script anyone tried it?
Edit:maybe it is for a specific variant, i think for D6502
Mine D6503, anyone with D6502 tried it

format /data /cache and /system and then try to install

I tried it with multirom maybe that is the issue, i will try later as a normal installation

I'm already familiar with custom roms, i know i have to wipe everything

It won't boot. Tested setback times both fresh install and dirty install over cm12.1.
