[Q] flashing roms & towelroot & lock bootloader - Xperia SP Q&A, Help & Troubleshooting

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

Hey thanks mate, I was wondering what lb stood for. Not be too long until I am contributing to builds here. I use to help build kernel and bug fixes on xda back in 2010
I love the android Dev section just don't want to brick my.device
Thanks again

Where is thanks button gone?
Also can I flash rom just like I use to
Download on my phone put in sd card boot to recovery then.flash
Going.to go for it soon will keep you informed what roms I try etc

Found the thanks button.
Need more help before I will flash a rom if you can pal?

That guy needs a medal, he's been awesome in this.scene from the beginning

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

I tested it and working with xperia arc 2.3.4 (.42) fw!
I suggest you changed the title something like "cmw recovery on locked bl and more". I think many want recovery with but hesitant to unlock bootloader. Thanks for posting.
works perfect on rooted stock arc locked bootloader
sounds wonderful. I shall try on mine too
Can I install ROM now from the dev section in the forum?
can confirm that this does not work on the Xperia acro IS11S
so does this allow a recovery menu for devices with locked bootloaders, does that mean we can flash custom firmware on these devices. if not what are the benefits of locked bootloaders having a recovery menu

Try it! lol
If we install CWM using this method, is there a way to remove it if we need to claim the phone on warranty or anything?
Also can more people confirm this definitely works with stock fw, locked bootloader

Are you sure that'll work? You still have a locked bootloader so custom ROMs probably still won't work. I think it more for backing up stock ROMs and installing mods etc.
ah ok i guessss your right....can we flash themes?
I have no idea. I'd like to know actually. Would make it a lot easier to test things that may cause a boot loop and be able to just flash back to stock without a full reset.

You can't upload the CM7 because CM7 need another Kernel. CM7 don't working with the stock kernel! If you make change kernel you need the unlocked bootloader phone.
I think that this works:

you are right,

Yes, but this is just a rom in ZIP file, just flash with CWM over the original stock rom. Test it if you have time!?
How about adding a (second) post / sticky in this Topic, with Roms, Tweaks etc. that work by CWM flashing... (locked bootloaders)

am i able to install any rom with flash tool? that guide is v good btw i was following it but not to actually install a rom as i cant see root yet...
oh...
first you need to do some research before you go playing, always keep a stock FTF to hand just in case anything goes wrong
ROOT
Install CWM
Stock rom which allows you to do a bit more modding
A must for the XZ: Pure sound
CWM Will allow you to install Rom's and mods. but at the moment you will have to say on Andriod 4.1.2 becuase you will have a locked bootloader and if you unlock that (You have to enter a certain code in a program ) you really need to know what you are doing becuase or at least something
P.S. Here to help but you do need to read, not just jump in at the deep end and hope for the best
DIDNT WANT TO POST AGAIN: Is your bootloader locked of unlocked (Have you entered something like fastboot.exe -i 0x0fce oem unlock 0xKEY)

my questions on the z1

Hi guys, I'm getting a z1 tomorrow
Should I get c6902 or c6903 ? I don't need 4g but I want a device that has many mods/ ROMs. That's all I need.. Second, what is lb and UB ROM? Third I want to install ROM on new device, the steps of installing ROM is something I don't understand.. My experience with grouper nexus 7, unlocked it, flashed it.. But z1, how to do that? Can someone explain basics to me?

- depends. Is your device that you've ordered support LTE? If yes, then you'll get C6903
- LB = Locked boot loader. A state where you can't flash custom kernel
- UB = Unlocked boot loader. A state where you've unlock your boot loader, so you can flash custom kernel.
- which steps?
- there's ROM which can be flashed even your bootloader still locked. So, it depends on what ROM you wanna use.

1. Backup your TA partition (just in case you want to roll back to 4.2.2, and get back your DRM key)
2. Check for updates using OTA or Sony PC Companion
3. If there's update to 4.3, apply the updates
4. Before we step further, I wanna ask you, do you wanna keep your bootloader unlocked?
Well. We don't know when exactly 4.4 update is available. Let's hope we'll get this in December.
Hi
For me it doesn't matter if BL locked or not, I read there is no problem in that in 4.3 regarding camera issues.. But I have zero knowledge on how to deal with rooting and flashing the z1.. Im not going back to 4.2 for me its either aosp 4.4 or Sony ui 4.3. As I said I have zero knowledge so if you can elaborate more about how to do it that would be highly appreciated
hi

There is no better way than follow this steps on Page 2, Post #16 http://forum.xda-developers.com/showthread.php?t=2588331&page=2
No body here was clever at the first time so just read carefully. This is the only way to get the full root on your device.
If this help click on thanks.
Well, I found that out through YouTube.. I downgraded my c6903 to 534 fw and rooted it, installed the recovery dual and flashed ihackers 2.1 , yes I did ta backup but I didn't unlock the bootloader. I dunno what's the benefit of doing so, although I emailed Sony and I got the unlock code on my email as they replied... I'm only missing an app that control the led color of notifications led and Google now since I'm not in the US region.. That used to work fine on 4.2.2 but no worries.. Thanks guys. You really helped me a lot and I think this is a great device, I have been using it since Tuesday. And I rooted and flashed it this morning. One problem is that I dunno how to enter recovery so I flashed the ROM right after I flashed the recovery.. I understand now that there is a flashable zip? Things are much easier with the nexus line

All the FTF have to be flashed on your device via Flashtool v0.9.13 compatible with your device and they are not zip. Recovery is in zip and all what you flash from recovery is in zip file.
Yeah I did that.. It had 257 fw, I flashed 534 with flashtool then I rooted by vroot, then ta backup with some bat file through computer and USB debugging, then installed recovery by bat file as well, which rebooted to recovery, I did factory reset/wipe, and flashed aroma ihackers 2.1 without custom kernel then switched off and flashed baseband and kernel by flashtool and rebooted, done..
Just like that. And you should be the one without knowledge?
Well, I put my mind to it.. And when I do that I usually succeed... But I still have unanswered questions, like what are the benefits of unlocking bootloader? How can I control led light color for different applications notifications.. I tried light flow and illumination bar, both didn't work.. Lastly I haven't got used to the camera ui as I haven't used it much and I already applied xposed 20 mp mod.. Lastly,, I like to thank you for all your attention and care and everything ... I really appreciated it
as i know the unlockbootloader is the only way to flash custom karnels.
i dont know mutch more then that, just switched from ios so i'm new to this.
I forgot to backup my TA does that make an issue and if, what kind?
sorry for thread steeling

Like @stianly said Unlocking Bootlader is needed to flash custom kernels only.

Yes, it's a problem, without TA you lost your DRM keys permanently which are needed to re-lock your bootlader. You also lost the warranty of you device definitely.
yea i know the waranty and drm
but what does the drm keys do i lose some functions?

Yes, Bionz, X-Reality and probably Bravia Engine or something like that but your phone still working properly. Some users do not notice the difference with or without this features.
Ok I tried gravity box, can't find notifications led settings... Can you be more specific on this? Thanks...

[Q] Can you flash a rom on xperia z if it was made for the z1, z ultra for example

I want to flash a rom from the z1 onto the z but I am not sure what would happen if I was to do such a thing. Has this been done before, if so what has been the past consequences? If you have done this and it has worked please let me know, this is only a question to be informed and want to see what you say. Also I am just getting impatient and I don't want to root my phone just for kitkat. Any help would be greatly appreciated, Thank you.

People probably have done this before, and the consequence is a non-working phone Not only is the SoC different, but pretty much everything is a generation newer on the Z1 than the Z, so pretty much nothing will work, and might even permanently ensure nothing works on your phone. Good things come to those who wait, or unlock their bootloaders
Okay on a related note is there a 4.4 kitkat rom for xz that does not require root and unlocked bootloader? or one that I can flash with unlocked bootloader that does not need root. The less work I have to do to flash the rom the better.
No. You can only flash stock based roms on a locked bootloader and even then, you need root in order to install a recovery to flash them.
There is not a stock based 4.4 rom in any case.
As for roms for unlocked bootloader, there are a few in the development section. You will not need root to flash them, but will have to use fastboot to unlock your bootloader and flash the custom kernel from the rom.

[Q] ViperX Concept Marshmallow by Jenkins-84

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
