So I cant unlock bootloader :( - Xperia Z3 Compact Q&A, Help & Troubleshooting

As the title of thread says, I cant unlock bootloader (bootloader unlock allowed: no)
I have rooted and got custom recovery and flashed a modded stock rom, but I now want to flash cm or rr rom and both require bootloader unlocked.
Is there a workaround or something as its silly that I cant unlock officially (I have code from sony but it wont work)
please help

Bump anyone

I'm in the same boat, bootloader unlock not allowed. Unfortunately it seems that the only way that might be possible is through Sony.
Kinda sucks as there's some roms I'd like to try..

Thanks for the reply, thats a shame looks like I have to stick with modified stock roms

Bootloader locked or unlocked ?

How do i see on my Nexus One if my bootloader is locked or unlocked ??
I am newbie on Nexus G1 - sorry.
thanks by spirotop
Hi,
You will see an unlocked icon at boot.
Like this: static.arstechnica.com/N1_unlock.png
Sorry, can't post link yet.
What do you need to do ?
Flash a custom rom ? Don't need unlocked bootloader for that now (unless you are in 2.3.4)
Re-lock bootloader to sell phone ? You can't.
I don't see any icon at boot. I have installed Mark Denver's ROM 2.3.5.
Well if you don't see the unlocked pad lock at the splash screen that means your bootloader is locked. And just so you know you can do almost everything with only root access you don't need an unlocked bootloader.

Questions From a Would be Owner

Hello guys,
Just a few questions so I know what I am getting into
1) The phone can be rooted. However, if i want to run on a custom ROM or use mods such as the music mod, I would have to unlock the bootloader, yes?
2) Once the bootloader is unlocked, I would lose the 'Bravia Engine' feature of the phone. What else will I lose? For those who have lost it, is the trade off, of being able to run Custom ROMs and mods while losing the 'Bravia Engine' feature worth it?
3) If I have to send the phone for warranty, I could just re-lock the bootloader and send it back for warranty. Is there a chance somehow that they'll reject the phone if they detected that the phone's bootloader was tempered with?

No clue since mine isn't/can't be unlocked. The only reason for me to unlock the BL (Even though it can't be done) would be, to flash a custom kernel, beside that I don't see any other reasons why I should unlock it.

Once it's unlocked there is no way back.
So if you want to root your phone, use custom roms (without custom kernels) you don't need to unlock the bootloader.

Thank you very much for the reply.
I assumed as such from reading some posts initially, but then I went to the ROM section (If i am not mistaken) and there is a post on how to unlock the bootloader and then there is the Why section where it says that you could then use custom ROMs and mods which then confused me.
If i can use custom roms and mods without unlocking the bootloader, then I'll definitely be getting this phone.
I'll take advantage of this thread to ask one simple question: once we rooted the XZ and flash the Mods we find useful, we no longer get updates from the official Sony firmware in the future, right?

First backup your firmware with http://forum.xda-developers.com/showthread.php?t=2188129
You can go back at any time to your original firmware and you can have the updates via pcc or sus.

[Q] Does MoKee ROM requires Unlock Bootloader?

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.

maybe but I wasnt able to write the boot.img unless I unlocked my bootloader.
confirmed that it REQUIRES Unlock Bootloader to install MoKee

Yes, I have confirmed that it REQUIRES Unlock Bootloader to install MoKee.
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.

Any custom rom requires boot loader unlock.

If it say no the answer is still no. You cannot unlock bootloader or install custom kernel. How ever you still can install custom rom which uses stock kernel.

thank you, could you point me in the right direction with that atleast? I tried looking for that also and still could not find any thing i read i still would have to go in to fast boot mode but when i get in to it all i get is a black screen.
You only get a black screen with fastboot, the commands are issued from the computer.
However you do not need fastboot to install custom roms with a stock kernel. Look in the development section for them

[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 .

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.
