I just got a W8 with a battery date of 11W51. So I can no safely unlock the bootloader without paying someone, something I do not want to do. I read the development forum and was about to root and install xRecovery. Now I would like to install a custom ROM. Am I able to do that without an unlocked bootloader?
Yes.
You may install a custom rom without unlocking bootloader.(only those one which require stock kernel).

Is there anyway to be sure a custom ROM requires stock kernel if it doesn't say so on the title or the thread?

@OP's second question
It is usually mentioned in the title. However if it's not, then you can read the thread to find out. The search feature helps you there.

I have an N1 that I unlocked and rooted and was running CM7 RC1 when I decided to try the stock Gingerbread. This switch went perfectly, but now I don't think I want to stay on the stock GB but I can't seem to get ROM Manager to boot into recovery to allow me to flash another ROM. Do I have to do something differently now? BTW, I do not have root on the 'new' GB.
Thanks.
Unless you flashed a pre-rooted version of Gingerbread, you will have lost root and your custom recovery...
If this is the case, you have two options:
1 - Flash a custom recovery through an unlocked bootloader.
2 - passimg back to an older version of Android and root again...

This is your problem. ROM Manager installs a custom recovery, but only when your phone is rooted. You need to re-root GB.
Can I ask them how people flash custom recoveries without having root? I see threads all over the place that say that you don't have to root your phone to run these custom ROM's.

You have to root, but you don't have to unlock your bootloader.
You have to do one of the things:
1) Root.
2) Unlock the bootloader.
Rooting allows you to bypass security mechanisms from within the OS, and flash the custom recovery from there.
Unlocking the bootloader turns off the security mechanisms, and you can flash whatever you want directly from bootloader.
Both achieve the same thing, but in different ways.
Root privileges in OS are lost upon official upgrades.
Unlocked bootloader is never lost.
Unlocked bootloader allows for an easy way to gain root in the first place, regardless of the ROM.
How does an unlocked bootloader allow me to flash whatever ROM I want? ROM Manager won't run without root? Am I missing something? I've read the wiki's and threads about rooting an N1 and they all just seem to stop at unlocking the bootloader, well, my bootloader is unlocked but I can't get it to boot into CWM so that I can select another ROM. Is there another way to do this?
ROM Manager is only one, and not the most successful nor most powerful, way to flash ROMs or recovery. ROM Manager was made for non-understanding people to make the process look and feel easier. The most powerful way is directly from bootloader - which needs to be unlocked to allow it.
If you read all the threads, you'll see that unlocking the bootloader is just a first step - you can look carefully at "installing custom ROM" guide in Wiki. Or, for example, here:
http://forum.xda-developers.com/showthread.php?t=636795
Read the Wiki, look for recovery installation instructions using unlocked bootloader, execute. I suggest Amon_Ra's.
Hi
Sorry for the dumb question, I dont want to root my phone (the Barclays app, I know it can be worked around) but do want to play with ROMS. All the instructions I've read say to root the phone, but do I have to to be able to put new ROMs on. Thanks a lot in advance.
Yes you obviously need to be rooted to unlock your bootloader, to flash a recovery and to flash ROMs

If you want to install Stock custom Roms like MagicRom you will need only root
but if you want to instal a Custom Rom like cyanogen-mod, miui you will need root and unlocked bootloader

It's true only if the rom doesn't have a custom kernel and most roms do. If the kernel changes, you need to unlock the bootloader. Also, you can't flash a custom recovery without unlocked bootloader.
Hi all.
I was a big xda user / developer around the times of x8 / x10.
Things have changed alot
I've now got Xperia sp and is rooted via towelroot and Installed the recoveries. Bootloader is still locked and I am on stock everything
I NEED help. Can I flash a custom rom. Really want to but not.sure.if this will brick my phone. So here I am asking.for help
Thanks in advance and.if.you help I'll be clicking your thanks button.
Thanks again
Yes you can install custom roms, head over the roms zone and find the ones that in their names says "LB" which means Locked bootloader, the ones that say "UBL" are for unlocked bootloader and if the roms says both it means they work on both locked and unlocked bootloader

Please do me a favour and have a look at that
Can I install it I have root via towelroot and have recoveries installed and.the same build number 12.1.a.1.205?
Yes you can, that rom is for both LB and UBL, and thanks alot mate! i've been browsing xda for a long time now but never had a chance or didn't want to make an account, but oh well, anyway's.. i think there might be better roms for you to try, that one seems like it won't get any more updates..
Also, there's cm, paranoid, pac-man for Locked bootloader, you can take a look on them too
Just make a backup of your current rom in case you want to go back
And sorry for the late reply, wasn't at home!
What about the build number do I have to find one same as my.stock build number.
Nah, anyways, there's a FTF thread that has stock firmwares to download in case you want to flash stock firmware via FlashTools
Kernels are just needed for recovery? Or they're needed for ROM? I checked all the posts but I am confused, i am new to these stuffs.
I am about to flash SlimKat right now but I don't know what to do? Flashing rom is very easy but the previous part about kernel stuff mad me confused
I have unlocked bootloader and XDualRecovery. Can I flash this rom with these stuffs?
for rom.
Stock kernel wont boot custom rom as i know.

The answer is in your question....
Custom kernels require unlocked bootloader
understand!
thanks
i thought it was only for custom ROM
I somewhat knew this from a long time ago but I've forgotten. Its been a while since I got a new phone
also as I remember, they force u to unlock bootloader thru SONY so that warranty cant be claimed, mainly afraid of people who OC CPU and GPU which can damage the device (which is reliant on custom kernel)
As I don't hale enough posts to ask this in Development section under ROM trend, I'm creating new one.
So I used ViperX for a long time, but now I'm back to stock and also restored DRM keys. I've notced, that you can flash Marshmallow Concept without unlocking Bootloader. So why ViperX need to have unlocked BL? In fact it's just rooted Concept with some addons. Isn't it possible to install XZDualRecovery and then flash ViperX through this? Can anybody explain this to me?

Its not that easy bro xD
To make it short its because bootloader, if you re-lock it you need get invited or flash stock otas, which will mean no recovery (only the stock sony one, you cant Flash stuff only signed otas from sony) also you dont have no root in /system so you cant modify it.
If you unlock it your able to Flash a custum kernel which contains recovery, that means also that you can use customized roms, such as normal root and modify all partition, also you can get twrp recovery.
If you want all answered, read Sony Concept Initiative Thread from jenkins-84 on the last 10 sites theres allmost all your question answered.
Peace
