I have unlocked the bootloader of my mobile(canvas a1) to install the CM12 mod. It been a week since i unlocked it, now is it possible to relock the boot and make my mobile as unlocked mobile? I previously had sony mobile in which bootloader unlock and lock is possible. In the same way is there any procedure to be followed so that i can relock the mobile?
P.S: I am getting a notification on the screen below as "OEM UNLOCKED" when ever i switch on the mobile.

I will receive my galaxy nexus few hours later and plan to unlock my phone. Is there a way to hide the unlock logo after I unlock the bootloader or Can I unlock the bootloader, then root the phone and relock the bootloader after to clear the logo but still get the root access. If yes, then how to relock the bootloader?
fastboot oem lock will re-lock the bootloader
But will I still get the root access of my phone after I relock the bootloader and will the unlock logo disappear when boot up after I relock the bootloader?
p.s. It is retail version
why do you need it locked?
I don't like the unlock logo at bootup and the warranty detail only state that I will lost the warranty if I unlock the bootloader, so relock it in case I need warranty, it may cheat them
so then you relock it if you need to. Development for this phone is very young right now so you'll likely be doing alot of flashing. I flash different rom/kernel combinations probably 3-5 times a day with how often things are updating right now. Besides the little unlock symbol is pretty awesome
I know the development is young, that's why I post this. I just need to confirm
1) Is it possible to relock the bootloader in retail version
2) Will the unlock logo disappear after relock
3) Will the phone can still get the root access after relock the bootloader
Thx very much and please reply me if anyone know!!

1) Yes, "fastboot oem lock"
2) Yes
3) Yes, while "fastboot oem lock" does not touch any of your data, "fastboot oem unlock WILL delete all your data. None of these processes can remove root access, the only way to remove it is to reflash the system partition, either by flashing it manually or through an OTA update.

I went to see if my bootloader can be unlocked from the sony website.
I followed the instructions by putting that code into my phone dailer.
Under the section if it says my bootloader can be unlocked, it says no.
Does this mean I CANT use custom roms?
Is there no other way to unlock the bootloader?
You can always unlock the bootloader, it's just a matter if it's free or not. It all goes back to whether you can use fastboot or not ( the tool used to flash kernels). If you bought your phone sim unlocked it more than likely means fastboot is enabled and you can unlock for free through sonys tool and be on your way to flashing custom kernels. If your phone is sim locked or you paid to get the sim unlocked by a code then fastboot will be disabled. So to rephrase: turn your phone off, hold the search button and plug it in to your computer, if the status light goes blue (and you're not on a CDMA one, r800x) then fastboot is enabled and you can unlock for free through sonys utility, otherwise you're going to have to use a pay service like this (~$24):

And to answer your question, yes and no, while it's not possible to flash ROMs that use a custom kernel like cyanogenmod without an unlocked bootloader you CAN flash stock based ROMs through the recovery made for locked bootloaders.
I have an R800A from Rogers.
The LED doesn't go on at all when I press the search button.
When I goto sony's website, I go into the phone settings, where it says if the bootloader can be unlocked, it says NO.
You mentioned a paid servers. Is unlocking the phone by allowing it on another network the same as unlocking the boot loader?
No, that's sim unlocking. Confusingly a bootloader unlock will actually sim unlock you as well though, the difference between the two is a sim unlock is a code and the bootloader unlock is done through test points. So ya, if you didn't get the blue light your only option for unlocking is a paid service, sorry.
Well actually an unlocked bootloader allows booting of custom(unsigned) kernel images and can be achieved with various means according to the situation.

Which is what I said in my above post... And the only ways to unlock it are:
- Through sony's online tool if fastboot is enabled and you have an IMEI (sorry CDMAs)
- Or a test point unlock, such as setool2 or omnius, which will enable fastboot
Oh ok sry then, thought u were being general.

Try flashing a kernel is the obvious and simplest answer.

So if my bootloader is locked it won't let me flash custom kernel like(boot.img of cynogenmod) or it will brick my phone? You link doesn't explain anything on how to check bootloader unlock status."bootloader unlock allowed:yes" will be for those devices whose bootloader can be unlocked but it doesn't tell you if bootloader is unlocked or locked.
I simply want to unlock my bootloader.Then flash cynogenmod.I want to make sure bootloader is unlocked properly before flashing cynogenmod kernel.If flashing boot.img on bootloader locked device won't brick my phone then i am ready to go.Just need conformation on what happens if i flash custom krenel and rom in bootloader locked mobile accidentally.

When your rooting status says
"Bootloader unlock allowed: yes"
Then the bootloader is locked..
If it says
"Bootloader unlocked: yes"
Then your bootloader is unlocked..
Simply dial *#*#7378423#*#*
Then find your rooting status..
And I think you should use the official way to unlock bootloader.

HAhaaa unless that shopkeeper imported the phone,unlocked bootloader and flashed a kernel.Place where i live doesn't have authorized sony mobile distributors.So they import from somewhere.
My booloader was unlocked whole time after purchasing it.It was new when i bought but no sure now.Anyway i am satisfied with my purchase a year ago as i haven't got any problem till now except that famous house crack.
I have flashed Cynogenmod successfully.Thank you all for the help.You guys gives some courage for nervous guy like me who are tempting to do new things.
Hi all, I need to relock the bootloader, flashing back stock MM or LP didn't solve the issue for me, neither hard resetting, bootloader is still unlocked and the message appears on every start in the high left corner.
Can You help relock or it's impossible for now please?
It's not possible to relock once it's unlocked. It does tell you this when u unlock it.

thanks for the answer, I did not remember that message. Strange for me that noone found or searched a method to relock for selling the phone :good:
Getting it relocked is the only way to send it back for warranty claim. I wasn't able to get it recognized by my computer so that I can run fastboot comands on it - the right one is ./fastboot oem lock

Did you use the proper fastboot.exe? What OS is your computer? If it's windows try these.
It seems that in order to get fastboot operational, you need to have a working bootloader. So, after a couple (hundred) of tries - DO NOT FLASH KDZ (REFURBISH) your LG G4, it still boots once in a while and if it has your account and data and it will be faster to get to fastboot mode and get the bootloader locked again. Can somebody confirm that you can execute "fastboot oem lock" on an unlocked device? This will save us a lot of time trying to get the device to that state...
for me it is impossibile. If you have a g4 with bootloader locked and you doing fastboot oem unlock it says that it is no possibile...you must follow the instructions that lg provides with file unlock.bin
So is impossibile relock bootloader with fastboot oem lock...I hope that anyone find the way to do it...
Well unfortunately it is not posible to lock the bootloader via "fastboot oem lock" I'm waiting for user @warloxfre for some more info on his ideas (fingerscrossed)
Solution to Lock Bootloader:- Go to Fastboot Mode,
Type :
fastboot oem relock (Bootloader unlock code without bracket)
I finally submitted my device to service centre
Needed a help in locking bootloader of Honor 8 Pro Indian Variant DUK- L09 C675.
I flashed Latest Oreo update through TWRP with the help of DUK_FullOTA_ROM_flasher method but the bootloader is still unlocked....
If anyone could help me with this as I have to visit service centre related to mic issue.
Connect to your computer, restart to fastboot mode and use "fastboot oem lock". Make sure you have a stock recovery and ROM on it, because the locked bootloader will not boot anything else.

Relocking bootloader by this method will erase all data?

No, it won't. But you should still have a backup whenever you mess with fastboot.
