Relock Bootloader Command - ASUS ZenFone 6 (2019) Questions & Answers

Does anyone know the command to relock bootloader? I flashed the raw firmware but every command I tried to relock failed. I need to make a warranty claim but can't until the bootloader is relocked.
Commands I have tried but failed:
fastboot oem lock
fastboot oem asus-csc_lk ( taken from ROG Phone 2 forums)

Code:
fastboot oem asus-back
fastboot reboot (if it doesn't reboot on it's own)

Thank you! Worked perfectly. You rock!

Nice to hear it
Just remember you won't get FOTAs anymore because Asus is blacklisting unlocked phone's IMEI.

I wonder if there's a way to fake-send the IMEI to Asus when doing the unlocking process.

I don't know how exactly the bootloader is being unlocked but something tells me the unlock code is generated with the use of IMEI/SN. Wrong phone IDs = wrong key, however this is only my speculation.

I did the above command and now it says the deivce is corrupt and can't be trusted and will not boot. No press start to continue message. Can you please help me or guide me to unbrick this phone? Thank you.
P.S. I guess following the guide-unbricking-zs630kl can help? Thank you.
Edit: Nevermind. Followed that guide and unbricked it myself.

Were you able to claim the warranty? Did you do the official(Download from ASUS site) or unofficial bootloader unlock?

After you unbricked the phone, was the bootloader re-locked? Also, were you able to successfully file a warranty claim or return the phone? tnx

He has bricked it while locking the bootloader, so yeah, it will be locked. Warranty will depend on where you live. If you'll have faulty motherboard, they'll probably replace it for free but technically this is mandatory action only in the EU because just unlocking can't be considered as warranty void. Of course until they prove you that you bricked it.

Well, first you'll need to explain how you unlocked the bootloader on a snapdragon S8+?
It's done by the crom_service tool by jesse chan

I never heard of it. FWIW, with a device that has an unlockable bootloader, one would use FASTBOOT, not ADB. Command is:
Fastboot OEM lock
With that said, I haven't a clue if this will work on your device.

The g9500 (the snapdragon s8 family in Hong Kong/china) is unlockable using the crom service/KIWIBIRD in steady thing.
Unfortunately I have no idea what is involved. Why do you want to relock? Did you flash something already? FYI if you are 0x1 WARRANTY_VOID you cant undo that part
My problem is, that Samsung Health is detecting " rooted device"

Reinstalling Recovery after Removing Root and Re-locking Bootloader

I feel like an idiot for asking this, possibly because I am one (which can certainly be debated), but here it goes.
As the title states, I pretty much screwed up in not making sure that I had everything in place after removing root and relocking the bootloader. How would I go about re-flashing the stock recovery? I'm running a Pixel 2 and would like to be able to side load updates in the future.
Thanks in advance for any guidance!
Is OEM unlock switched on ? Did you try unlocking your bootloader using fastboot?
If you can't access the recovery because the bootloader keeps crashing, then you just hard bricked your phone and there is no way back
I was able to unlock the bootloader again, so I don't think all hope is lost.

You unlock bootloader with the official apk, so you cannot relock it, and moreover, like it's explain when you install the official apk for unlocking bootloader, your warranty is now void. I remember it was written when i unlocked bootloader on my zenfone 3 with the official asus apk.

Thank you for your reply.
I want to relock my zenfone.
When I boot up the phone, I get the same sentence.
It is not related to the warranty of the phone.
This is Korea, not the place where the asus phone is regularly distributed, but it does not repair the trouble in Korea asus.
Knowing this, I bought the phone.
I just want to keep that sentence no more when the phone boot.
When relocking again, the sentence seems to be rattling and asking questions.
I want to know how to relock.
I am also looking for an original recovry and boot img that fits this phone.
If I can save those files, I think relock is possible.
Or I would like to find a way in this phone that this phrase can be paved.
Thank you.
I will read your writing carefully.

You can not get rid of the message, even if you relock the boot loader.
Help unlock bootloader zenfone 5q (x017da)
I don't have a high enough post count to start my own thread, but this is the closest related thread I could find. If I should post this somewhere else, please advise.
I tried the official unlock bootloader apk and I keep getting an error message. It says it is an unknown error message and it may be a network issue. I tried troubleshooting on the zentalk forum. They asked for my Imei number and then told me the servers are fine that I'd be using and I would need to have support perform "Imei checking". Support had no idea what that meant. The zentalk support person suggested I ask for help here as they can not provide any additional assistance.
I've looked and using adb and fastboot I can get my phone into fastboot, but then after echo>key.txt I try:
fastboot oem get_unlock_key key.txt
FAILED (remote: 'unknown command')
fastboot: error: Command failed
My goal with unlocking the bootloader is to try to enable gcam and hopefully improve the camera capabilities.
Does anyone have a suggestion on what steps to unlock the bootloader? I don't believe there is any way to use gcam without unlocking the bootloader first, but I'd there is a way to do that, I'd appreciate some direction.
Thanks.

Put the phone in fastboot mode, then run `fastboot flashing unlock` from a PC. If it says unlocking not allowed, you're out of luck, it's a brick now. Never lock your phone without being 100% stock on both slots

No idea. I've never relocked unless I am completely stock and take at least one ota first to make sure, along with full factory resets before and after updating.
There are others here that claim they where able to unlock again and save their phones though so maybe it's possible.

Unable to unlock bootloader (OEM unlocking disabled)

Hello,
I couldn't unlock the bootloader as the OEM unlocking's disabled and i can't access system! Everything's erased!
Any help????
A bit more info might be helpful mate.
What did you do to arrive at the situation you are in?
Can your pc see your device via ADB and if so what are you using: latest platform tools or toolkit?
Can you boot to stock recovery or bootloader?
Without any of the above info its going to be extremely difficult for anyone to give any kind of answer.

The device isn't recognized via ADB.
I can boot to Bootloader
The phone was working fine with the latest google stock android 10, i decided to lock the bootloader cuz the phone was getting overheated so i thought it'd be a good idea to lock the bootloader. Prior to do that, it asked me to erase everything! I erased everything and when i tried to reinstall the stock image it asked me to unlock the bootloader!!
The problem is that USB debugging isn't enabled and the phone is empty with no system!

Ouch! That's a right old situation you have there mate, with no OS installed a locked bootloader and no ADB function I'd have to say your phone is non recoverable!
Sorry mate but I can't see anyway out of that lot.
Maybe someone else a bit more knowledgeable might chip in but I'm deffo out of ideas.

Try switching slots, assuming the pixel is an A/B device. Maybe you still have a bootable system in your other slot and I don't think you need an unlocked bootloader to switch slots

Make sure you have the latest fastboot. On the bootloader your phone will either say "slot a" or "slot b" and you should type "fastboot --set-active=b" if you are on slot a or "fastboot --set-active=a" if you are on slot b
still didn't fix the problem... any probable solutions please?
