AOSP for locked bootloader - Xperia Z Q&A, Help & Troubleshooting

Hello There!
So i just got my new xperia Z from my company and it is for two years and i had to pay for it anyway.
I have choosen this one cause i knew its a good phone and have loads of devs, and i didnt check if there is any aosp for locked bootloader i was sure, and i thought i can unlock mine anyway.
I was about to unlock my bootloader and i saw i cant do it i googled for 3-4 hours , and there is no way to unlock it even if you pay for it or something.(T-mobile hungary )
At the moment there is no AOSP rom for locked bootloader.
Here is my question : Sony updates this phone really fast, almost as AOSP or 1-2 months i see some good devs making sony custom roms for our device, Can any of you make AOSP only pure cyanogenmod thaths all i need. I'm Sick of the bloatware that sony has in their roms.
I just boot up my phone and half the memory gone.
Are the sony built kernels and custom roms kernels so different? Is it ompossible to make an AOSP rom ?
I would love to see one , i will definately use it and test it for bugs.
I know **** about android development (or any other) but i will get into because i dont want to use ****ty sony roms for 2 years
Cheers!

There is no way to get AOSP on a locked device. Is not only that the kernels are different, but the thing is locked bootloaders only run signed Sony kernel.
If memory is your main concern, flash a debloated, stripped down version of Sony's roms.

yea but we should build an aosp rom for the sony kernel or is it that hard?

in theory its very possible but what will you really gain?
You will have to use pretty much all original binary blobs, and will end up with some framework changes.
is there anything specific in an aosp build that you want?
the Z has one of the most closest none GPE roms around as it is..
as others have said why not just debloat or install a debloated rom?

I've mentioned this before but it never went anywhere, if Sony's AOSP kernel is signed then what stops it being put in an ftf to be flashed, and if that was possible would that not open the way to getting locked down bootloaders unlocked?

It looks to me that Sony haven't provided anything for the AOSP kernel but the sources via their AOSP website (I could be wrong, but I don't see any kernel images on their github, only sources).
In that case, anyone wanting to use it has to build it themselves, therefore it will have to be signed by whoever builds it.
So, if everything I said is correct, then it's no use for getting this running on locked bootloaders.

Agreed. Now if we could figure out the Sony keys, or someone leaks them, it is a different story.

I think either situation is highly unlikely.
I don't think it's at all possible to "figure out" keys. If it was, the security wouldn't be very.....secure.
As for leaks from Sony, has this ever happened, for any device in their history?

No I don't think it has. You never know when someone might make a mistake, but I'd agree it isn't something to hold out hope for. Kexec or similar is the best bet, otherwise no AOSP for the locked bootloaders!

Hey!
I use one of the debloated rom i gues (monxified)
and i open the process list :

small apps manager
smart search my xperia
location based wifi
semc cnap provider
theese are the useless running apps
so useless installed apps list :
i was able to start to write the list but it will take like 30 minutes
anyway FXP rom size 246 mb + gapps 88mb 334 mb
monxified rom : 545 mb existenze ultra 741mb excelzius 643 mb and thoose megabytes mostly sony bloatware
can u point me to a rom that doesnt have theese inside?

My Xperia Z with 100% stock firmware and lots of extra apps only has 1 GB of RAM in use. That's the advantage of having 2 GB of RAM, you don't have to worry about memory usage. So just chill out and enjoy your awesome phone
AOSP would ruin a lot of the nice features and design of this phone anyway.

Just to let you guys know, it is possible to run AOSP Roms on locked Bootloaders. I was running CM10 on my Razr (XT910) and Motorola Devices where always locked untill the HD.

yea and there were good working stock based roms, even dualboot etc with locked bootloader. but here somebody said it before no dev will bother about locked bootloaders if the device can be unlocked for the 70% of the Z users, and razr couldn't be unlocked.
anyway monixified is a great rom its fast and etc but i miss cyanogenmod features like theme chooser and nice weather on the lockscreen

so anyone doing this? or nope?

well you can always remove them yourself with titanium or a root file browser ? remember to backup rom/apps first, as there can be consequences from removing system apps.. alternately try googling for sony stock sys apps that are safe to remove

many define a custom rom by the option to compile a kernel from source.
we cannot include a modified kernel, without semi-bricking our devices.
but we can change startup and we can init kernel parameters a second time, to allow loading of different services and libraries, which for some is enough to load a customized kernel for graphics mod, removing adware, loading modules and porting cm10,aokp and other roms, like sense or similar miui roms.
i personally believe a port of highly modified rom, is custom. other believe its not a real rom
anyways with the clockworkmod i made its possible, as long as you do the same hijack when needed to change kernel init services or libraries to load.

lack of support from more developers i guess, seems other hardware devices are more popular, and propably much easier to get donations on that on a device with locked bootloaders where development stops at the locked device. today, donations is very popular and driving many towards popular devices.

rom with orginal sony's apps ??

first i have a w8 with 12w02 and i see a lot of roms with stock kernel but all of them (as i know) based on CM, so i really miss sony's apps like alarm, clock...
guys pls tell me a rom is a ported from xmini, lww... so we both have ginger bread and sony's apps
tks
But they are good roms, just try. As i know its not possible to port from 2011 devices. Cause they are armv7, x8 is armv6

Try the old (but good ) GingerCruzt rom. This have SE look, and use some original SE app. Up to 8.4 it works on stock kernel (the latest 8.5 require custom kernel). And some xgin roms use some SE apps (widgets, contacts app, etc) around version 5.6-6.0. These roms is abandoned, and hard to find working download link. Unfortunatelly only these old hybrid solutions exist (cm7 + some SE apps) for stock kernel. If you lucky, maybe in the android development section you can find newer stock based roms what contains original SE apps (I not follow every rom threads), but do not want too much, these roms usually contains only SE launcher, timescape, some original widgets, dialer/contacts, xperia themed message app, 50-90% xperia look, and some apps what have modified UI to look similar to the SE apps.
Try semc Debrand by achotjan little buggy but stable and workable, does require custom kernel tho

unfortunately, the op's date is 12wXX. so unlocking his bootloader is a huge risk.
@op: i understand your preference for sony's stock apps. but there are a lot of nice alternatives for them. if you don't want that, stock rom is pretty good (considering the situation).

tks you guys all, i'll try these roms.
i tried to ub my phone few days ago and got a hard brick
but luckily it's under warranty, so now i've got 11w21 hurayyyyyyyy
I guess u got lucky Now i guess u can unlock your phone's bootloader. For custom rom with sony look and feel i would recommend Gingercruzt 8.1/8.5 for stock kernel and 8.5 for custom kernel

I don't know...About the risk i think that it would be better if you won't unlock your bootloader,because you don't know what date of manufacturing you have, and it's not with old kernel.This is the date of manufacturing the motherboard.
@voncount from who you know that you have 11w21 ?
I think GingerCruzt or XGin..

[Q] Is it worth unlocking bootloader?

IMHO not worth it. Keep your X-Reality and BIONZ and other Sony exclusive software. I hate buggy camera and sleep-of-death issues, so I keep my Z1 on 4.3

Sony stock ROM is the best
Except you don't want Sony UI,then you can unlock bootloader & flash CM11
You will lost DRM keys if you didn't backup,X-Reality won't work for Pictures & Movies
No feature will disappear from unlocking the bootloader. Stated by Sony themselves. Before 4.3 stuff did happen though.

Pre 4.3 this was the fact. Camera ceased to work and other functions aswell. The DRM keys did matter there. The tech guy from Sony also confirmed this.
Kitkat version though this is all fixed. And like he said to quote him "Nothing will change software wise with just unlocking a bootloader under Kitkat, aslong as you dont flash custom roms ofc."
So to translate this: The DRM keys aint used in KitKat. And it is very easy to confirm this yourself. Google the functions that people say will stop to work with no DRM keys. None of thoose has stopped to work with unlocked bootloader for me on KitKat 4.4.2.
And for the camera, the camera working worse under KitKat as you also can google and find information about. Unlocked as Locked doesent matter, and this is possibly one of the reasons why ppl still think, Bionz, X-Reality and other functions stop to work with unlocked bootloader.
But is it worth it? Well that is up for anyone to decide for themselves. Since KitKat, the phone aint working so well anyway imo. So if it would die on me i wouldnt care. I will probably not buy Sony in future though, they used to be good but something has happened.
For real?

Unlocking bootloader in 1 2 3...:fingers-crossed::fingers-crossed::fingers-crossed::laugh::laugh::laugh:
Now I'm curious:
How, where or why are custom ROMS faster than stock ROMS?
I really can't complain about the speed of my stock. I haven't unlocked my bl yet (no need for) but I doubt you'd see much difference in speed between stock und cfw.
It was different on my sxs. Latest aosp or fxp was definitely more fluid but the z1 is a powerhouse.

Nobody said they are more faster, they are tweeked but at the moment on Z1 they are in development so before see a wonderfull stable Custom Roms you have to wait.
BTW, many Custom Roms are based on Stock Kernel so you will never see any difference. The heart of the tweekness and fastness on Android it's the Kernel, it's the main reason.

You can install CyanogenMod if your bootloader is unlocked. If you do that you will lose all your data and warranty but I think its worth it. You will have more control over your phone (privacy settings etc) and much more.
If you want to do that you should do a nandroid backup before and most important a TA backup. TA backup is for relock the bootloader if necessary (so you have warranty again). You can find TA backup tool in this forum, just search for it.

You need to downgrade to other version (for example .257), then root this and do update to the new version. Then you will have 754 with root.

Unlocking the BL is for rom development mainly. You will be able to load CM11, but so what. The stock rom is excellent for most people and its nowdays to tweak the interface in so many ways its silly.

C6903 - CyanogenMod 11 for Locked Bootloaders - Help needed!

Hello guys, I'm acquiring some info about how to build the CM11 to Honami with locked bootloader.
 @Olivier already did it to Xperia S and @letama said to me that MAYBE we can do the same to Z1.
I'm not a dev at all, but for sure I have some skill (I hope!).
So, I have to ask first, did anyone already tried it? Worked? Didn't work?
If anyone is willing to help, please, let me know.

Well, this solution doesn't use kexec. It basically hijack stock firmware android boot to boot the alternate firmware but it's using stock kernel, that's why it can work with locked bootloaders. The only requirement is that cm or aosp should run on stock kernel and doesn't require a modified kernel. As you have kitkat on your device, there is a good chance that it does.
But it doesn't, that's why it does not work and a modified ramdisk (Hence modified kernel, hence unlocked bootloader) is needed
Hence kexec is needed, but that seems like a lost hope on Xperia Z devices
Nothink is imposible i hope
No, nothing is impossible, but there has to be enough effort spent on it.
Personally I don't think there will be as most devs got bootloaders which can be unlocked...hence they do not need kexec
In future its always preferable to check this before purchase
mabe don't need to unlock bootloader but workaround this - mabe multiboot or kexec will be more developed because more phone will released with LB and this is their new policy :/

No, nothing is impossible, but there has to be enough effort spent on it.

But it doesn't, that's why it does not work and a modified ramdisk (Hence modified kernel, hence unlocked bootloader) is needed

Ramdisk is not a problem... When I say kernel, I mean zImage, not zImage+ramdisk: we extract cyanogen ramdisk in the boot hijack.
Kernel drivers combined to Android hal is what I meant and could cause problem depending on how Cyanogen was developed and how Cyanogen kernel source code is far from stock one. That's why we're usually stuck on Cyanogen with the same Android version.
Another solution is to hack Cyanogen code to support stock zImage. It's not for the faint of the heart, but it could be the only solution.
Greg's absolutely right, if your bootloader unlock allowed status is no or you're unwilling to unlock it then i'm afraid you're out of luck, i'm not saying it's impossible that just isn't true, but again as Greg's said this more than likely isn't going to happen as it would take some talented folk a lot of time to accomplish it, with the Z2 having been released and the vast majority of people able to unlock their bootloaders there is little call for someone to have a crack at it.
in all fairness though, the rom's that are available for locked bootloaders are pretty damn good and the launchers that you can install these days gives a near perfect android experience, you'll only be missing things like Halo and custom kernels along with a few mods and such that only appear to be available for cm based roms and the like.

Flashing ROM with Locked Bootloader?

Hi there,
At the moment I'm running Android 4.4.2 Stock ROM, but I want to switch to MIUI V5. I would like to know if it's possible to do this while having a locked Bootloader.
P.S.: First I used the towelroot-method to get root acces, then I installed SuperSU and CWM Recovery. So that's already done.
It should be possible. Take a look at this thread: http://forum.xda-developers.com/xpe...-miu-z-4-2-2-multilang-v2-5-10-3-1-2-t2467408
Just follow the steps for locked bootloaders.

Thank you for the fast reply! I'll try it. By the way are there any bugs in the ROM I've mentioned? I can't read any Chinese and Google Translation doesn't translate that well.
Isn't MIUI based on AOSP/CM? If it is, then you cannot flash it on a locked bootloader.
Edit - It seems the rom that gripfly linked to can be flashed on locked bootloaders. Disregard my post. ?

Too bad it's an outdated ROM. I would love to see the newest MIUI ROM running on this beauty, but I'm too scared to try it out and mess it up, and then risking to lose the DRM key.
Edit: Are there any good ROMS with nice GUI apart from Sony's UI for the Xperia Z? The MIUI ROM V5 is based on Android 4.2.2, which is more a downgrade than an upgrade...

There are many good ROMs on the forum.
Actually, UI varies from person to person so it's very difficult to say which one is better, you can search in the forum and find a suitable one.
As for me, I highly recommend PA which include many good features.
Locked bootloader means stock based ROMs only.
