Hello,
I just Unlocked the bootloader of my Samsung A50.
Now I want to undo the bootloader unlock, I mean I want to lock the bootloader as previous.
Is there any way to do this?
Best regards,
Habib.

Locking bootloader won't be any useful as with unlocking knox is tripped which is a hardware fuse.
Only way to properly lock and restore knox is to change the motherboard.
Bootloader Lock
I don't know if this makes sense or something
I have Galaxy A50 A505F/FD and I recently unlocked it's OEM. I don't know if OEM is the same as bootloader. So I wanted to root the phone but I was unsuccessful and I always had that warning that comes up when you are starting the phone that prompts you that the bootloder is unlocked so it is not protected by Knox. All i did is pass through the unlocking options and locking the bootloader came up again and i successfully locked it again. It is now functioning perfectly. No problems. Maybe that's what you need
Please bare in mind that all your data will be erased so it is better you back up first
-back up all your data
-shut down the phone
-hold volume up and down at the same time
-plug-in your cable connected to pc
when the blue-ish screen comes up, release the buttons and you can also remove the cable
-select bootloder unlock option by long pressing volume up button
-select Lock bootloader
-phone will erase all your data
you are set to go
Thank me later

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 have a Sony Xperia M Single SIM and I download a cyanogen custom ROM. The problem is I can't enter to the bootloader or the recovery mode to install the ROM. I did this process:
I shut-down the phone, then i get pressing and holding the power button until the phone get on, and i pressed quikcly the button volum up too. And the phone doesn't response, it take me to the "Enter your pin" normal mode.
One more thing:
the phone is blocked on Orange here in Spain, and i searched if does exist any method to unlock the bootloader or something like that, and I found in the sony website some procedures to know if your phone can get unlocked, and i entered the following number *#*#7378423#*#*, then to: Service info > Configuration > Rooting Status. And the Bootloader unlock says No!!!!
If any one can help me to install a custom ROM I'll appreciate that. I have no idea how I can do it, specially on Sony's phones, on Samsung's phone I didn't had any problem.
I'm sorry for my English is very bad
Your bootloader is locked (and it's not unlockable), so, no way of using custom ROMs in your phone ate the moment...

So why it is Locked. The is a several phones has it unlocked. Why the mine ???
Can you explain me why is locked and no unlocked?
You should unlock it manually check the forums to unlock the bootloader
Just to make clear, Xperia devices has two types of lock: SIM Lock and Bootloader Lock. The SIM Lock prevent you from using SIM cards from other carriers, and you can remove your SIM lock in any device by paying to your carrier or to a service center (in some countries the carrier removes the SIM lock for free in some cases).
Then comes the bootloader lock. With a locked bootloader, you can't boot in recovery mode because there isn't a recovery mode in stock ROM (trying to do so will just start the phone normally). You also can't flash custom recoveries or kernels (needed to use custom ROMs) with a locked bootloader. All Xperia devices comes with the bootloader locked from factory, but in most of them they're unlockable...
If you bought your Xperia device directly from a retail store, your bootloader is certainly unlockable and you can proceed with the method you tried (go to Sony website, input your IMEI, get your unlock code, etc.). If you bought your Xperia from a carrier (Orange, in your case) then your bootloader is very likely to be not unlockable, and that's your case, your bootloader isn't unlockable, as you already checked by going into Service Menu with *#*#7378423#*#*. If your bootloader isn't unlockable, you are out of luck, you can't do anything, there isn't any other method...
And further info if you get an unlockable Xperia device in future: by unlocking your bootloader, your warranty is void and your DRM keys get wiped, because of that, some proprietary Sony apps won't work anymore (Mobile BRAVIA Engine, TrackID, "Download Music Info", PlayStation Certified features,etc). So, if your bootloader is unlockable, you should to a TA backup before unlocking it, so, in future, if you want, you can relock your bootloader and get your DRM keys back, so the proprietary Sony apps works again...
Also, removing your SIM lock doesn't unlock your bootloader as well as unlocking your bootloader doesn't remove your SIM lock. They're two different things, completely independent of each other...

Read the OP, its bootloader can't be unlocked
I want to know as I don't want to completely screw my phone again. The phone works now just with an unlocked bootloader but the power key prompt annoys me and I'd like to relock it.
I have a galaxy A50 and recently rooted it and installed twrp recovery and then again flashed the stock image.Now when I boot the phone it shows that ugly bootloader warning.Can I lock the bootloader now?
And also
Will I receive updates?, as the phone status is official.
Im not sure but i think you lost OTA updates even after relocking the bootloader since your knox status is tripped but thats not a big issue since you can still use odin to update your phone.
to remove the bootloader warning you have 2 options:
1- Relock the bootloader since you have stock official rom. To do that you need to turn off the phone, hold V+ and V- and connect the usb cable to your pc, the phone will enter a "special" download mode, long press V+ to relock your bootloader, the phone will factory reset with locked bootloader .
2- Use this method to just remove the warning and keep your phone bootloader unlocked with official or rooted/modded firmware.
Hello everyone.
I recently bought a Samsung Galaxy S22 SM-S901B/DS 256MB in the UK. I'm trying to unlock the bootloader to get root with Magisk.
First, I updated the operating system to the latest version available. After that I managed to toggle the OEM unlocking in the Developer Options but when I restart to Download mode I don't get the option to long press the volume up key to finish the process. There's a line that says "OEM UNLOCK: ON(U1)". That very line read "OEM UNLOCK: ON(L1)" before I toggled the option in the Developer section.
I tried to install an AP file modified by Magisk with Odin 3.14 but at the end of the process I get the error "Custom binary (VBMETA) blocked due to remaining installment balance" and I have to flash the original OS from scratch to be able to use the phone again.
Could anyone please help me here?
AFAIK, currently, there is no way!

That's what I get at step 4. No matter how long I press Vol Up + Vol Down, i can't see the option to unlock BL.
Looks like some restrictions for unlocking are enforced by the region specific Firmware.
You can try to flash alternate stock firmware from different region (probably Asia).
This could hard brick your device. So, it is your choice to proceed or stick with current Working Firmware without root.

It might be that you are already bootloader unlocked
Try installing twrp for your s22

Thanks for your reply.
Do you know of any specific firmware that allows to unlock the bootloader for this specific model?
Can I cross flash a firmware from a different region?
Can I downgrade my firmware?

1. You can find some clues here:

2. I have not tested cross flashing Samsung Firmware so I cannot give any feedback.
3. Downgrade from A12 to A11 will certainly fail. I have tested this just last month.
> "Custom binary (VBMETA) blocked due to remaining installment balance"
That's seems like another layer of protection by Samsung, so that you first pay off the loan for the phone, and then you can root it.
hi @chinchulin01 ,
is there any news for the root?
At what point do you get stuck?

For my phone model they use a EVR firm, so I downloaded SamFw_FRP_Tool_v3.0 and changed the CSC of the phone to EVR. I downloaded the most recent EVR firm and I tried to flash it with Odin 3.14.1 modified, but I keep getting a Fail message.
No idea what to do next.
