Xperia Z5 Bootloader unlocking not allowed after having unlocked it once before? - Xperia Z5 Q&A, Help & Troubleshooting

When I got my phone, the unlocking status was unlock allowed: yes
I unlocked the bootloader and installed a custom rom from androplus that had supersu.
after the rom was installed the unlocking status is unlock allowed: no
now I have a nagging notification to update android on my phone and it can't because I'm running a custom rom, and I can't update the rom because the bootloader is locked. what do I do?

So, basically you unlocked your bootloader to flash a custom rom and now you want to receive official ota updates from Sony?
If so, you have to stay in stock roms (flash with flashtool in flashmode or Xperia Compation in repair option) otherwise you need to wait for developer of custom rom you installed for an update.

no not quite, as I said I want to update the custom rom, but I can't flash another rom because my bootloader has been locked and I can't unlock it again.
the escape plan would be to flash stock rom back onto it, but I'd like to keep supersu if possible.

no, the site that provides the guide and key to unlock the bootloader specifically says I can't unlock it if the status says unlocked allowed: no
are you saying I should try anyway? other forums says there is no way around it if unlocked allowed is no.
the reason I haven't tried is the threat of having my data wiped without actually unlocking it

If you can enter recovery then make a full backup

[Q] Doubts with locked bootloader and unlocked bootloader?

Hi.. I have Sony Xperia (ST21I) with build number 11.0.A.4.27 (android version 4.0.4). Few months before it rooted this phone with a unlock flash tool. I am sure that the phone is rooted now. And i managed to install a Clockwork Mod too with CWM installer.apk file. And tried too boot into clockwork mod. It worked. Now I don't know which bootloader I am having? A locked bootloader or a unlocked bootloader. This question may look silly to people who are really fluent to android. I never carried any process to specifically unlock my bootloader. I am asking this question because I have read that "You can't root your phone without unlocking bootloader". If what i read is true does that mean i am having a unlocked bootloader?? So now is it possible to flash a custom rom for unlocked bootloader? Thanks in advance.
only few roms

Dial *#*#7378423#*#*
You probably have a locked boot loader as bootloader can only be unlocked by a specific key.
I too have a xperia tipo and it can be rooted without unlocking the bootloader. I used unlockroot to root it.
Thanks Guys!!

Can I unlock bootloader on 5.1.1 eXistenZ rom?

How can I unlock the bootloader on my rooted 5.1.1 d6603 eXistenZ rom without having to loose all my data? And if that's not possible, then how can I unlock the bootloader period? Does it matter if you're rooted and can you do it while on 5.1.1?

You always lose data when you unlock the bootloader.
It does not matter what ROM you are on or if you are rooted.
Any ROm that works on locked bootloader also works on unlocked bootloader
To unlock the bootloader go here http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
Will I loose root and my dual recovery and if so is there root for 5.1.1? Thanks for the help.

No, (well you shouldn't) as root and recovery are installed to the system. Unlocking the boot does wipe data though.
And if once you have an unlocked bootloader you can always root any firmware on any android version. That's the main reason to unlock the bootloader. You will also be able to delete recovery from your system and have a custom kernel with recovery built into it.

Unable to unlock bootloader?

Hi, I have a Tipo s21i.
Looking to flash a custom rom and possibly root. Although looking through a few guides it says I need to unlock bootloader. But when I go on service menu suggested on sony website it says my bootloader is not unlockable.
Do I need to unlock the bootloader to install custom roms?
If so what can I do to do it as it says its not unlockable?
Thanks
First check if your bootloader can be unlocked. Open Phone and dial *#*#7378423#*#*
Service Menu should appear, go to service info, Customization Settings, at the end if Rooting Status: Bootloader unlock allow No you can't unlock bootloader. If it's missing you can't unlock it. If it is said Yes you can. You can use Flashtool or official Sony way to unlock it. Search XDA there are plenty tutorials on how to.
Good Luck!

if the status of the unlock bootloader is no then you cannot unlock the bootloader if yes then you can after unlocking only you can flash any custom roms

Not able to lock my bootloader again in my Redmi Note 7 Pro

I sucessfully installed Orange Fox Recovery in my Redmi Note 7 Pro (violet). But then after that I wanted to go back to the stock rom so I flashed it with Mi Flash. The Rom which I flashed was Global Stable Fastboot Rom (Version 11.0.8.0) but after flashing an error appeared that the system has been destroyed. Then I tried to unlock my bootloader, that took place successfully and my phone booted but the bootloader was still unlocked, I want to lock my bootloader. But whenever I do this the System Gets Destroyed.
You probably have the Chinese version and are flashing the Indian rom. Try to flash the Chinese rom and lock the bootloader and see if it works.

I am also having the same issue. I have tried multiple methods. I flashed Chinese rom, and then tried relocking the bootloader. It did not work.
I also tried flashing MIUI 10, and after flashing the fastboot rom of MIUI, I tried relocking bootloader. It did not work as well.
I want to relock my bootloader.
After unlocking bootloader I am facing just one issue, that is, my internet goes off (volte signal + internet) while receiving an incoming call. While it does not goes off and internet works fine when making outgoing calls. Are you also facing this issue? I am using Airtel.
Also, can someone please help us out?
