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 .

I have tried unlocking it with and without a custom ROM on my phone, it says 'Bootloader Unlocked: Yes' on the service info and i also only have the option to RELOCK my bootloader when i try it on the flash tool. Does this mean that it may actually be unlocked already?
EDIT: im also using This custom ROM which has custom kernals to select from
-Thanks

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.

Hi there.
After i unlocked* the bootloader of my phone i got stuck in a bootloop, then i had to flash the TFT all over again...
The problem is that i don't know if the phone is already with bootloader unlocked or not...
how can i check it?
I was thinking on trying to do the unlock steps again, but i'm scared of being trapped on another bootloop...
Is there a way to check if the bootloader is already unlocked?
PS: The bootloader unlock allowed is yes.
thanks you guys.
Flash doom kernel via fastboot with this command:
Fastboot flash boot boot.img
If you get an error than your bootloader is not unlocked.
You can flash back to stock kernel with flashtool,flash the kernel separately.
Sent from my C6603 using xda premium
but if i got that error and confirm that the bootloader is locked, is there any chance to harm the phone? or need to flash the TFT again, etc etc
use flashtool to tell you
Another more easy approach .
When bootloader unlock allowed says yes and be2 is working in Album, then it is still locked and you can start the unlock steps again.
How can i use flashtool to tell me?
@DevShaft
Before i could see in a flash the bravia engine working on pictures. There was a little delay... Now i can't see it.
Probably the bootloader is unlock.
If i try to install Doom's kernel via recovery and the bootloader is LOCKED, can it do any harm? thanks guys

I unlocked my Xperia Z and in Service Mode I can see 'Bootloader unlocked: Yes'.
Now my phone is running on latest C6603 firmware and DooM Kernel.
To my surprise, BE2 still works! Music info download still works! TrackID still works!:victory:
But not picture enhancement in album right? Hope you backed up TA partition before unlocking

im surprised at how this 'check bootloader is unlocked already or not' thread is confusing.
by the previous post, there is two 2 ways
1. try to flash doomlords kernel via fastboot, and if it doesnt flash means its NOT unlocked.
2. flashtool.
however the 2. flashtool method is very vague.. dont think anyone elaborated it.
So my same query is that if some error occurs after trying to unlock bootloader, and have reverted back to the stock FTF rom in original working state.
How do one check to see if my bootloader is unlocked or not?
whats the best easiest method???
Thank you!
just type in *#*#7378423#*#*
Go to Service Info > Configuration
And check the Rooting Status
If its Bootloader unlock allowed:Yes/No, then its not unlocked.
And if its Bootloader unlocked:Yes, then its unlocked.
Thanks

That just tells you weather you can unlock your bootloader via the command / flashtool e.g. If you carrier has locked your phone
On a unlocked bootloader the BE2 engine still works on videos ect just not pictures.
All I would do Is flash doom kernel or advanced stock kernel via flashtool (Click on lightning bolt /fast boot / click on put device in fastboot via adb now phone will enter fastboot then select kernel to flash which is in the middle on the pop up screen and then flash if it will take around 0 . 5 seconds ) if it fails then you bootloader is locked due to it cannot complete the command if is successful then it's unlocked and you can flash custom kernels take about 2 mins to do all in all

unblock SM-G350E bootloader
Can any one tell me how to unlock bootloader for SM-G350E
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???

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.

I am not allowed to post on MoKee thread so I will post my question here.
http://forum.xda-developers.com/showthread.php?t=2761807
I am not a newbie and have been following XDA for 6 different devices and more than 5 years. But I just didn't post enough.
I am currently on SONY Xperia ZR (C5502) 4.4.2 (rooted). I have been trying to flash MoKee 4.4x for the past few weeks but in vain. I bricked my device few time already by trying and have to revital it with all kind of tools (Flashtool, Sony Update Service, fastboot).
I guess now my question is - "Does MoKee ROM requires Unlock Bootloader?" In the last post of that thread, someone said that it MUST be Unlock Bootloader. Is that true? The only reason I care so much about this is because I screwed up my device every time I unlocked it.
I was using the "fastboot.exe -i 0x0fce oem unlock 0xKEY" method.
I am currently using 10.5.A.0.230.
Your answer will be really appreciated.

Yes just like any other rom out there you will need an unlocked bootloader. The reason is because you have to flash a custom recovery such as CWM and to do that you need to unlock your bootloader. I recommend unlocking you bootloader using flashtool instead of the command. Because it is just easier. When I was trying to unlock my bootloader I experienced problems doing it the way with the cmd. And what problems does it give you after unlocking and how does it screw your device? Thanks!!
PS: Try flashing a custom recovery because maybe your bootloader is already unlocked.:good:

I have installed -=[XZDualRecovery]=- with locked bootloader, so I don't think the reason is about the flashing of the recovery, maybe is something related with kernel flashing. but I'm not sure.

I unlocked my bootloader with Flashtool this time, instead of commend line this time. That fixed the problem I used to have.
But I used the CWM comes with XZDualRecovery to install MoKee 4.4.4. It works out fine.

I tried to flash many roms with flashtool but nothing change.
You lost network coverage but does it still offer to unlock the sim? And does that succeed?
And just to be sure, you did flash the correct stock ROM your model (C5302/C5303/C5306)?
If your bootloader magically relocked itself then sony pc companion should work (I know it sucks), have you tried repairing your firmware using that?

That is so unusual that you might want to check with fastboot if the bootloader really is locked. You can do that with the following fastboot command:
Code:
fastboot getvar secure
This will return "secure: yes" if the bootloader is really locked.
Anyway, have you tried a generic ROM for your device from this thread? http://forum.xda-developers.com/showthread.php?t=2311964
If you have a north american device (C5306) you might need a provider specific ROM.

If it says "no." you can't unlock it. You can install custom ROMs as long they are stated that are for Locked Bootloders. Do not attempt to flash a ULB ROM onto a Xperia SP with a LBL because it will soft brick your phone. Attempting to unlock the bootloader when the the status says "no" it's not recommendable and could hard brick your phone.

As mentioned above, if the phone says "no" or doesn't say anything at "bootloader unlock allowed:" thing, then there's no way around that. You can still get custom roms though. There are some roms that will work with locked bootloaders.
Pro tip: Always buy generic phones if you want the best from xda. Always check what you're going to buy.
