Custom ROM for a Locked Bootloader? - Xperia Z Q&A, Help & Troubleshooting

Hi I am new to this forum, so my apology if I have started this thread in the wrong place.
I have recently found out that my Sony Xperia Z phone's bootloader isn't unlockable! :crying:
I have rooted my device, and modded it for the best experience I could get. However, since my bootloader isn't unlockable, I can't install any custom roms! And without a good rom I cant make my phone... well, mine! I was wondering if there are any ways around this whole locked bootloader thing.. If there's a process to actually unlock it? If not, I guess that's alright... But PLEASE tell me there is a way to flash some kind of custom rom to my device with a locked bootloader. I was really interested in getting the Pac-Rom until I found out this news. I am no expert to this whole rom thing, so try not to be too techy for me please. If there is any custom roms available without a unlocked bootloader, PLEASE give me a link or something. It would be greatly appreciated! Thanks!

I don't know how it looks like with stock based custom roms and not unlockable phones. But I think it would be work because it is for locked bootloaders also. You can find them also here on xda. You have to give a look at the thread name to see if it is for you. It must be written LB. (lb= locked bootloader)

OK, I understand you cannot ask in that thread, fair enough.
But a bit of reading will tel you that you can not flash that rom on stock kernel.
Please read this you will make much further steps forward if you try for yourself instead of asking..
its the old story of giving a man a fish or a teaching how to fish.
I remember when I was a noob at Android Rooting and Flashing, but now all of that changed. Now I flash tons of weird files onto my phone and flashed more than I can remember. I even hard bricked my TL before. ( i got a new one from warranty ). My question is... Why bump this old thread

help information needed**

hi, new to the forum and android for that matter was looking for some advice and information i have just renewed my contact the the carrier threeuk and took the sony xperia z (great phone) , i was reading about customs roms and all the other great stuff on this forum but i have a few questions :
when try to unlock the bootloader mine says "no" which is im guessing down to 3 uk blocking this so if i flashed and debranded the xz would that enable me to have "yes" in the service settings or do i have to contact 3 and somehow hope they would allow me to do this and if not and i still cant unlock my bootloader would there be any sort of hack or something in the future that might enable this to happen
thanks in advance for any feedback

AFAIK, if your device says "Bootloader Unlock Allowed: NO", there's no way to unlock it.
There are roms that work with BL locked also, if you're interested.
The only reason (For now) to unlock BL would be CM or Custom kernel.

In order to install 4.2.2, you need a CM based rom, so you'll need an unlocked bootloader.
The first thing you need to do is check if your bootloader is unlockable, so take a look at this thread.
After that, you need root and CWM (Locked BL, Unlocked BL).
Then, you need to find the rom you want (CM, PAC, AOKP (Kanged), among others). You can find more under development or original development sections. (These roms will work ONLY IF YOU HAVE UNLOCKED YOUR BL).
If you can't unlock your bl, you can also install Sony based roms, such as KA, RomAur, among others.

Infos about modding Xperia T

Hi to all.
I bought the Xperia T (lt30p) and i would say what is the best rom and the best kernel. Thank you!
Please use search, also there is no answer to this question so there is no point posting it. Especially add your have not said what you want from the Rom....
Is your phone's bootloader unlocked? You can only flash custom kernels if your bootloader is unlocked. Not all of our phones are able to have the bootloader unlocked. There are threads in the forum to show you how to check if your phone is allowed to have it unlocked. If it says "No", then right now there is no chance of having your bootloader unlocked. If it says "Yes", then you can unlock it through Sony's dev website.
There are some great ROMs for the XPeria T that use the stock kernel. Right now, I am using XPerimenT ROM v2.9 on my LT30a. It's a little old, but I really like it. It is based the official 141 firmware.

[Q] Camera with bootloader?

Sony has said that installing bootloader in the Xperia Z1 will disable the camera, but I've read that if you recover the TA, the camera works again. Is this true? If so, could I install different kernel ROMs (like CM) with a working camera?
I'm sorry if the question sounds dumb, I'm new to Android.

Firstly, you don't "install" the bootloader, every phone has one, you just unlock it to get access to it.
Secondly, you can restore the TA but that RELOCKS the bootloader so you cant use custom kernels.
Trust me, when this issue is sorted it will be big news so you will get to know it.
Currently this is the situation
locked bootloader = stock kernels = working camera
Unlocked bootloader = stock or custom kernels = NO CAMERA
No question is dumb if you don't know the answer, but please get used to searching before asking, that way you definitely wont ask any dumb questions
Thanks!
But the only ROM with the stock kernel is HONAM1Z, and I have no idea what features it has....
The other stock kernel ROMs are just updated firmware with root, but there are 2 that are basically the same. Which one should I use?
Do you need bootloader for mods? (like PureXAudio)
You choose any one you want. No one on here will tell you want you want, its up to you to try, test and decide for yourself.
As for other mods, no you don't need bootloader unlocked. That is only for custom kernels.
If you read the OP of each mod it will tell you the requirements and if it does not say "Requires an unlocked bootloader" then its fine to use on a stock kernel.
You will just have to root, install recovery and flash them.
Do ROMs need to be of the exact model number?
For example, you have a ROM for the C6903, but I have the C6906. Can I use the ROM?
Or if mine is build number 14.1.G.1.518, and yours is 14.1.G.2.257, can I still use the ROM?
And does the phone get unrooted when updated OTA? And how do you know which build number is newer?
I would first suggest you read the tutorials in the general section and the dev section.
Most, if not all, your questions will be answered there and I will only be cutting and pasting information from there.
As something to think about, when I first joined xda I spent a LOT of time reading guides and tutorials before doing anything to my phone.
I am not saying I wont answer your questions, but the answers are out there for you already and taking things steady will give you the best chance of learning and not doing something daft to your phone and bricking it.
Here are a couple of links to read

No need to read ALL the threads, but the opening pages contain important information. If after reading those you still have questions you can ask them in those threads and then people can help you there.
Best of luck, and I am available via PM if you need me
Thanks for the threads! They were pretty useful
Although I still have questions about ROMs. If your room is for C6903, and I have 6906, can I still use it? I would guess that you can, as the only thing that change is the baseband.
Also, what ROM do you recommend? Yours (http://forum.xda-developers.com/showthread.php?t=2504638), this one http://forum.xda-developers.com/showthread.php?t=2440408) or generic 534 (http://forum.xda-developers.com/showthread.php?t=2505796)?
Do you know what Honam1Z? (http://forum.xda-developers.com/showthread.php?t=2463675). I cant seem to find the advantages of the ROM....
Thanks again for answering my questions, mate.
And I'm sorry if you have received this same message by PM. My sent box appeared empty after I sent it, so I didnt think it reached you.

Camera Still Broken After Custom Rom?

HI Guys
About to get my Z1 but i have a question.
Have we managed to solve the issue with the bootloader being unlocked and the camera stop working?
Trust me, when that issue is fixed it will be plastered all over this forum so there will be no doubt about it.
If you find no new news then its still broken.
PS, you can still install custom roms without unlocking the bootloader, just not custom kernels.

Thats an interesting one, I come from an HTC background so used to unlocking bootloaders to flash a custom ROM haha
Of course thats what i thought on that it would be put on the forum.
