100% sure?
Sony Developers got back to me and said:
"We are sorry to say that it is not possible to relock the bootloader of your device after unlocking it. However, it is possible to get back to the standard Sony software using our Flash tool"
I may sell this device and would like to relock it

I'm not sure to what extent it can be relocked one day, but Sony phones generally have had a sort of fuse (meaning that even relocking _usually_ does not mean restoring to original state, unless you are able to do TA backups with a hack).
TL;DR: if you really want to resell it as locked, don't unlock it.

You can see on the Xperia 1, using fastboot you can relock the phone, and apparently this even restores DRM functionality (though no guarantees). But it will still have "YES" for "is ever unlocked" — so you'd be relocking it, but it would still be indicated in the service menu that this was once an unlocked phone.

Bootloader locked means u cannot load anything at boot that would tinker with the basic core of the device, like u cannot use custom kernels when ur bootloader is locked that is y ppl unlock their boot loaders Google for further info.
As for the OP's problem :
This is a known issue when u root ur device without unlocking bootloader, the solution to this is to do a full repair using Sony Suite which will result in loss of all data phone ,SD card etc .
check this link out its clearly stated over there
http://forum.xda-developers.com/showthread.php?t=2186368
Troubleshooting:
if your device has unlockable bootloader then after applying this hack the bootloader status will turn "Bootloader unlock allowed: No"
in that case dont worry the users have reported that doing a repair via SEUS will flash back stock firmware and turn this status to "Bootloader unlock allowed: Yes" (the same might also be achieved by flashing a stock FTF using FlashTool <yet to be confirmed>)
ROOT WILL BE LOST BY DOING THE ABOVE AND YOUR INTERNAL STORAGE MAY GET WIPED!
SO DO A BACKUP OF APPS & INTERNAL STORAGE ON AN EXTERNAL SDCARD/PC
How so some people can unlock the bootloader and some can't??

There is no flash counter to worry about with Sony phones...... Once you have unlocked bootloader your warranty is void even if you relock it.
Rooting does not void warranty.

Why?? I will relock bootloader, restore DRM keys, flash stock rom and will have same system when was when I bought the phone.
That I have "order" unlocking bootloader key doesen't mean that I did it.

Yes. But when you relock it, restore TA partition and flash stock there will be no sign that you have done it.
You may be correct... but most people will say that unlocking bootloader well void the warranty.

Yes, but you have given the imei of your device to Sony in order to get the unlock code. So if something happens to you phone and you get it at a Sony repairing center, the first thing they do is to read the imei from your device and check if it is in there database

And so?? They also have my phone in database when I bought it. I dont understand your reasoning.
I have buy a bulb yesterday. Just in case. Thats mean that I have to immediately change it??
No.
And for confirmation.
I ave do it twice.
First with my old LG GT540. (Stock -> root -> cyanogenmod (warranty off) -> flash stock without recovery, and fastboot (warranty on)
Second. Xperia SP (Stock -> root -> bootloader unlock (warranty off) -> existenz -> relocking BL -> Restoring TA -> Stock ROM (warranty on)
Both of them was rapairing without aditional costs.
End.

I unlocked my bootloader using the flash tool,didn't root or do anything that requires an unlocked bootloader.
And now i want to relock it,because my phone got water damaged and before i go to the Sony service center.
It's still fully functional(i can use it to do normal everyday things)but a small part of the digitizer is not working anymore,aswell as installing the 4.4 update.
Any help?
And will the warranty cover up non-user caused water damage?all ports were closed as well as the battery door.

If you did not back up your TA partition before unlocking the phone I think you will not be able to relock it. No warranty in that situation.

I just checked the Sony developer website,and it says that 2013 and newer devices,when unlocked,it well wipe all of your data,aswell as DRM stuff(track ID still works(and my data was not deleted)).
Are you supposed to receive Sony application updates when you've unlocked your phone?

It does not delete data on external SDcard, only internal memory. Also unlocking bootloader will disable Bravia engine, u will still be able to tick it in settings but it won't work. Not sure about updates.

Can you relock the bootloader using the tool provided by Sony?
Sorry for hijacking this thread. I have unlocked my ZR by flashtool also took TA partition backup before. Now i want to relock it as i need be2 and breathing light . My question is would i still be able to unlock and relock any number of times in the future?
I used to own an Xperai Sola. Before unlocking the bootloader I didn't know that I had to backup the DRM keys so that I can get back the "Bravia Engine" and "Download music Info option for Walkman" after the bootloader was unlocked. The information that we can backup our DRM keys came 6 months after I unlocked my bootloader.
These are my questions:
On Moto G 2nd gen do we need to backup something similar like the DRM keys of Xperia Sola?
What function do we lose when we unlock the bootloader other than Warranty? Does OS/Android update still work?
Does re-locking bootloader takes the phone back to its previous unlocked state?
@Falcon G
@vinaybaboo
@bhavin192
2. You can update phone after unlocking bl if you don't make changes to OS i.e. Xposed etc.
If you update even you have made changes to OS your phone will go into Bootloop
3. Yes Re locking and flashing stock firmware takes it to locked state
@NWKENT can answer this Questions more clearly
I´m also with similar doubts. I came from Samsung-way of unlocking bootloader.
Just to ensure if get it right, If I just put root on device, I still be able to update original rom from Motorola ?
It´s a pity we can change anything with xposed (in order to keep upgradable), bcos it´s small things we get used to, and we miss on stock roms...
Thanks,

Please @NWKENT @Falcon G @vinaybaboo can you kindly answer this question?
I guess if you wipe data and unnistall xposed and then flash stock recovery, you will be able to flash via OTA. No need to unroot

1. No you don't need any DRM keys
2. U lose nothing rather than your warranty. Ota works if you don't install custom recovery and change the kernel
3. The new locked state is different than the OEM locked one

Falcon G, thanks a lot for replying.
If the new locked state is different than the OEM locked one, then if a user wants to unlock the phone a second time, does he follow the same method he used to unlock the first time?
So, once the phone has been unlocked it is not possible to lock the phone to back to its OEM locked state?

Hello there, I was just wondering if anyone returned their Asus Rog Phone 2 for repair or simply returned it after relocking the bootloader.
On XDA there is a great guide on locking the bootloader here https://forum.xda-developers.com/rog-phone-2/how-to/guide-convert-cn-to-ww-rom-26-08-t3961042http://
So would be interesting to see if locking the bootloader is all we need to peacefully rma the phone or does asus have some other sneaky peaky something going on to detect if we ever rooted.
I am perfectly happy with my phone its just some people on my youtube channel were asking if its safe to return after relocking I just said I haven't heard of anyone doing so, so not 100% sure.

Most Android devices have a record in system chip. Once bootloader has been unlocked it will change status from 0 to 1 and even if you relock the device it will still stay as 1. Since you triggered the log thingy. So Asus techs will still be able to find out that bootloader has been touched. For example on Samsung devices they use something called a KNOX chip and when you unlock bootloader on a Samsung S9 or s10 the Knox chip will break and no longer work and status will say that Knox chip has been triggered with 0 to 1. That's how Samsung finds out if you have unlocked your bootloader on their devices. So Asus have probably a way aswell on their end.
You can return the device for repair but repair service will reject warranty repair and will put a price how much it will cost you to repair the device. Since they will see bootloader has been touched. So then warranty is voided.
I returned my 1st one because of no volte. Bl was unlocked, relocked using asus's app before the tool here was available. No issues, got a full refund.
I doubt they wouldn't repair it under warranty, unless it was actually caused by a bad flash, or something.

What Asus app did you use to relock the bootloader? I thought the only way to relock is to use a fastboot command. Asus has an apk for unlocking the phone, haven't heard of one for relocking.
