Downgraded, rooted, now want to install.... quick question.

Hi, thanks for reading,
Ok so my 6903 z1, i've downgraded it to .534, rooted it, installed dualrecovery and am sitting here wondering where to go next.
I wouldn't mind unlocking the bootloader so that I could install other kernels such as pimped kernel. But reading the dualrecovery thread it seems that it is only if you are using the original kernel. So my main question is, what should i do next?
use recovery to flash a zip of a new rom then unlock bootloader then flash a supported recovery?
or should i unlock bootloader now and then new rom etc? (was concerned about the camera issue unlocking the bootloader on <4.3 roms.... will it be "fixed" if i was running on a newer "flashed via recovery" ROM?)
any help is appreciated as I don't want to bugger up the phone like i somehow managed to last time i tried all this (had the IMEI disappearing issue)

If you want to unlock the boot, there is was no need to downgrade to root
Just backup your TA, unlock the boot, flash a custom kernel of your choice then flash away

oh ok. well i've done it now. although I've just checked my service menu
First, you should confirm that it is possible to unlock the boot loader of your phone by checking the service menu. In your phone, open the dialler and enter *#*#7378423#*#* to access the service menu.
In your phone, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.

and it says bootloader unlock allowed: No
So i'm guessing I randomly cannot unlock it anyway? (any reason why if that is the case?)

If that it saying then no way around to unlock your bootloader. BTW, stock kernel isn't that bad and with root you will be able to customize your room and get some tweeks.

so if i cannot unlock bootloader, does that mean i wont be able to use custom roms like Paranoid android etc which run off of CM and presumably a CM kernel?

and is it worth trying to unlock the bootloader in flashtool anyway just to see?
What options/next steps do i have then if i cant flash a custom rom due to not being able to use a different kernel?
Guess i can flash a modified stock rom and thats about it?

Unfortunately No, anything based on Custom Kernels you cannot install. Everything based on Stock Kernel you can Install, even Custom Roms.

oh bloody hell. ok so i'm now stuck in a sony logo boot loop after installing romaur v8 and installing the kernel (561) which it told me to.
any ideas what to do? guessing i'm going to have to flash the old 4.2.2 rom from scratch again

ok so now i'm back to .534 [nut] and rooted. any tips on where to go next so that i dont get stuck in another bootloop???

Just any Rom based on Stock Kernel.

I thought the romaur rom Was based on stock. Ho hum. Installed the pure stock one and it was OK thanks.

In Android developement thread all roms are based on stock - in original Android developement they are based on pure android.
Bootlooping is mostly caused when flashing wrong bootbundle/kernel.

Need help...!! camera functionality not working after unlocking bootloader

1stly i have 4.4.2 (.757) running on my z1 and i downgraded to .534 and i rooted the device by vroot and backed up the DRM keys successfully.. and then i flashed to .290 and unlocked the bootloader by flashtool and then downgraded to .534 and then installed the dual recovery and then flashed using the flashable recovery using recovery and then i found that camera is not working properly.. camera is opening and when i press the shutter butter its trying to focus the area and after focusing it freezes and doesn't shutter... so this is my problem... please help...

So much fail.
Do not use vroot, it sends your imei number to an ip address in China.
Also, unlocking your bootloader on 4.2 will break your camera, it clearly says so on the Sony official site about unlocking your bootloader.
Now, the solution.
Restore your ta partition.
Use pccompanion to update to the latest firmware
Unlock your bootloader again
Flash a custom kernel of your choice
Install super user app of your choice

.534 is 4.2 FW. the camera will not work with an unlocked boot.

yeah..!! i have done it.. thanks
but i have unlocked it in 4.3 does it make any sence by unlocking the bootloader in 4.3 and i didn't get any recovery mode... so.. i downgrader to 4.2 and installed the dual recovery as the thread says it needs .534 firmware to root properly...

I have to ask
Why are you unlocking your bootloader? What have you done it for? You do not get a recovery mode just by unlocking the boot, you have to flash a custom kernel with recovery in it
You either do all the downgrading and install dual recovery if you have a locked bootloader
OR
You unlock your bootloader, flash a custom kernel with recovery and install super user app
there is no need for both approaches and that's why you are getting problems

i unlocked the bootloader... i didn't find any recovery after unlocking so i followed the xzdual recovery process... but is it safe to flash a custom kernel.. and by installing only recovery without kernel does this doesn't help..

Why did you unlock the bootloader? What did you want to do with it?
You can not install a recovery without a custom kernel, xperia devices have no recovery partition, it can only be installed by pushing the ramdisks to the system partition or by flashing a custom kernel.
Please follow the advice I gave several posts ago.... that is your solution.
Then spend some time reading up on xperia device flashing.
1) Xperia devices have no factory recovery or recovery partition
2) Unlocking the bootloader is the fastest and easiest method to root and get recovery (If you are allowed to do it)
3) If you cannot or do not want to unlock the bootloader, then go through the downgrade, root, dual recovery process...

ok... can we get the recovery by unlocking the bootloader by official way??
and i saw a doomkernel... by installing it in fastboot can i get the recovery mode with locked bootloader or i should seperately install the recovery..??

Please follow my advice from post #2

Greg said fifteen times - follow his guide for here.
Yoy can't flash custom kernel especially not fastboot custom kernel on locked bootloader.
Whole purpose of unlocking bootloader is to flash custom kernel.
You are confused with all this informations, I would recommend that you read few things here on XDA to understand terms and other things.
You could seriously damage your device with just one wrong step.

[Q] Rooting issues - 4.3, IMEI, not actually rooted etc....

Hi All
So firstly I should say I only have myself to blame. I'm quite a techy guy so I just assumed i'd be able to root my phone without any issues and pick it up as I go. What i've quickly found out is i'm in way over my head and i'm an absolute noob!
Any advice would be greatly appreciated from those guys out there that actually know what they are doing. I have read many forums but i'm still lost.
My story is as follows:
- I have a Z1 that was locked on stock firmware 4.4
- I read that it would be a good idea to unlock the bootloader so i did this
- I wanted to root my phone but from what I read I could see I would have to downgrade the firmware to 4.2. So this is what i did.
- By doing this I lost my IMEI number, got very worried i'd ruined my phone. I tried many things to restore it, there were a variety of different solutions online, none of them worked. I eventually flashed a 4.3 firmware i found on this forum which restored my IMEI.
- I then read through a few posts of people who had similar issues and advice was given to downgrade again (if i wanted to root) but this time exclude the baseband etc. I did this, but lost my IMEI again! the advice didn't work
- So I then went and updgraded again! to 4.3 to restore my IMEI and network access
- There doesn't seem to be a way to root on 4.3 so my phone isn't rooted, that's ok. But when i try to use my banking apps they don't work! they say my phone is rooted even though it isn't! I have checked with root checker
- Like an idiot, i didn't back up the phone when i first started doing all of this, i didn't really know what i was doing so I am now in a situation where i have the worst of both worlds. They are, i can either 1. downgrade the firmware to 4.2, root my phone but not have a valid IMEI and network access or 2. stay on 4.3, have a valid IMEI and not be rooted but certain apps think i'm rooted so i can't use them.
So all in all i've just messed things up and i'm in way over my head. I would really appreciate some advice
Thanks

Yes you are right.
Also, there is no issue with losing IMEI when downgrading, it happens to everyone, but it comes back when you upgrade.
Also, if you unlock the bootloader there is no need to downgrade, that is a locked bootloader method of rooting
You should root before unlocking the bootloader in order to backup the TA partition, but you are too late now...
Solution
1) Use flashtool to relock the bootloader
2) Use pccompanion to update to latest firmware
3) Unlock the bootloader again with flashtool
4) Flash a custom kernel for stock based ROMs
5) Install SuperSU from the play store.
DONE!

I don't think so, the unlocked bootloader method is very generic and there are hundreds (if not thousands) of guides and probably as many videos.

Hi Greg, can you give me a bit more advice please.
i'm just looking at the tutorial to relock by bootloader. It says "before u relock bootloader u have to be on pure stock kernel (flash only the kernel.sin using flashtool), else the device WILL NOT BOOT after relock"
The problem is i'm already flashed on to an FTF image that was on this site. From so by doing this am i going to brick my phone? i'm confused and i don't want to make things work so your advice would be apprecaited
thanks

[Help][Q] Keep getting bootloop after UB

okaay so i rooted my phone again and decided to unlock my bootloader, i have verified that i am able to unlock my bootloader and follow all the instructions on the official sony website on how to unlock the bootloader. i get no errors during the cmd process either, i turn my phone on and it gets to the purple boot animation screen and then freezes. Is there anyway around this ?
EDIT: Also i used DooMlords thread and get the same problem? /: - I also use Flashtool but when i press 'blu' i only have the option to RELOCK my bootloader? :S

Anyone ? /: been looking for the solution all day

Just flash any desired custom form via fastboot and that's all, it should work.
When I unlocked my bootloader with stock firmware it doesn't boot anymore either, so I had to flash any other or reflash it again

Just flash a official FTF, then go to service menu, tests -> configuration and if your bootloader status is:
Unlock allowed: Yes - you can unlock your bootloader
Unlock allowed: No - your bootloader is hard bricked and there's no way to solve this (permanently)
Unlocked - congratulations.
I suppose your bootloader is hardlocked. check for yourself and if anything changes - quote

it says ---> Bootloader Unlocked: Yes. But iv'e tried to multiple times and still get stuck at the animation screen on boot up

If you are on a custom rom you just have to flash the custom kernel over it putting the phone in fastboot . No need to unlock bootloader again. Please ensure that the rom supports the custom kernel or there can be bootloops .

The rom that you gave link to is a stock firmware based custom rom, so it will have stock kernel.
I think it must be written Bootloader unlock allowed: Yes, on your phone
You will need to unlock the bootloader, PM me I will guide you how to do it.

How to install CyanogenMod 12.1 SNAPSHOT with Locked boot Loader

I am new to the installing the custom roms and all that i read about some stuffs but the unlocked boot loader is something that i can't risk .
Moreover i want to know that the CyanogenMod 12.1 snapshot with LBL ..... How should i do this please help and guide me step by step as i already soft bricked my phone once .......

1. Cm 12.1 for xperia sp has ended development
2. There's no cm12.1 snapshot versions, only nightly versions
3. There's no cm12.1 for locked bootloader yet
Flashing roms with unlocked bootloader is actually far more safer than with locked bootloader, as you won't accidentally flash a rom that says "for unlocked bootloader only" and get soft bricked. Roms for locked bootloader are often more buggy as they are very outdated. (I've tried one, it didn't even detect my sim card) Unlocking the bootloader for xperia sp is not really that dangerous. Tons of people here has done it for their phones.
