Unlock Bootloader a502cg

Hi Guys!
Users of this device a502cg need help to unlock bootloader.
Maybe someone has an unlocked device.

Asus did not publish bootloader unlock tool for you device. (Zenfone 5 lite) so you have no chances. This tool does not exist.

I think no. He can unzip ifwi.zip in system package and use same method for zenfone 5 T00J (A500CG)

Yeah. But where he get dnx?

hi guys
I'm need to unlock bootloader a502cg
Can someone help

there are files ifwi, help to unlock bootloader.
ifwi(21)
ifwi(61)

Zenfone 6's a601cg model unlocks bootloader with a600cg's files. You can try a500cg's files but its risky

Is it possible to relock the bootloader?

I'm holding off twrp + bootloader unlock because I want to be able to undo in case I need to use my warranty. Is twrp/bootloader unlock reversible? Many thanks

Yes. Flash complete stock everything, boot into bootloader, connect to PC, and "fastboot oem lock".

Is it sure that it works??I have a A2017G and i have open BL and a B29 Custom Rom and i want back to Lock Bootloader

Yup! I've done it plenty of times. You do need to format the data partition though. This could mean that it'll wipe out even your internal storage, so back that up as well!

Im on stock and then i go to edl and then i type fastboot oem lock but nothing happend

Boot into bootloader, not EDL.

and you can unlock it again afterwards?
Never heard of anyone wanting to lock the bootloader so I'd a newb in this kind of thing.

Locking it again is good for when you want to sell the device or send it in for warranty repair.

Yeah, the unlock procedure is the same as before. If you didn't restore the original boot image before the relock, then it's just a matter of booting into fastboot and unlocking the device. Note that this will cause your data to be wiped as well!

If you restore your boot.bin backup file from when your device was locked, does this lock the bootloader? "fastboot oem lock", "fastboot flashing lock" nor "fastboot oem device-info" does nothing for me. Is there any other way to check if your bootloader has been relocked?
Thanks

Hi there,
Were you ever able to re-lock your bootloader on your A2017G?
I just want root for now but understand that I'll need to unlock the bootloader first. Before doing that, I want to make sure I can re-lock the bootloader if needed.
Thanks for letting us know!

Guys/Gals, it is seriously as simple as using the fastboot command in reverse. I've done it a few times already with mine.
If you used the following to unlock....
fastboot devices
fastboot oem unlock
.....then you can use the following commands to relock
fastboot devices
fastboot oem lock
fastboot devices is not necessary, but I do it to make sure the devices is being recognized by ADB/FASTBOOT

Thanks for the answer.
But there are a few files to flash before using that command according to this thread.
Doesn't anything need to be flashed again (e. g. stock files or anything)?

Correct, but you would have already flashed those in order to use the unlock command in the first place.
Are you trying to relock on marshmallow or nougat?

My phone is only a few days old. I'm debating whether to keep it or not (considering the Mate 9, but the price is not the same - love the form factor and bigger screen though - sound won't be the same and I think I'll miss the MiPop button on the Axon (never thought that would happen )).
I'm on the latest MM (B10 - the A2017G model).
Following the mentioned thread, I got to the point of installing TWRP (the signed version), only to realize that besides making backups, there is not much else I can do with that without unlocking the bootloader. I really just wanted to flash supersu and install adaway fro the time being until development matured for this phone (maybe also play around with viper - had great results on my LG G4).

HI, I get the error "FAILED (remote: unknown command)" in ADB when I enter "fastboot oem lock". Any way to fix this?

Guys, can anyone help me? I really need to lock the bootloader!
How can I fix the error "FAILED (remote: unknown command)" in ADB when I enter "fastboot oem lock"?
I'm on MM B11 Stock.

Hi Guys,
The Axon 7 Model A2017U I just purchased has the bootloader locked and it is running LineageOS 14.1 - 2018032-Nightly-axon7. I need to relock the bootloader and get back to the stock MiFavor rom so that I can send the phone to ZTE for repair. Can you please explain to a newb in some detail how to achieve that.
Thank you.

There is no way u can re unlock the bootloader,but there is a workaround.Flash the beta marshmallow rom for 8916,watch the youtube video and check description,its a trick how to flash the beta.then simply flash twrp.the beta rom allows to flash twrp through fastboot.I found this method by myself over a month time

Is there a way to lock the bootloader?

I see plenty of guides on how to unlock the bootloader which as I understand voids the warranty. Is there any way to relock the bootloader if I need to? Maybe someone could link me to a guide?
I've had bad experiences with dodgy solder in 3 LG G4 handsets so I sort of see the value in a manufacturer's warranty these days.

In fastboot
"Fastboot oem relock YourCode"

Fastboot relock still show that the phone was unlocked before but to revert to original state you have to flash stock firmware using this guide https://forum.xda-developers.com/mate-9/how-to/guide-rebrand-chinese-al00-mate9-to-t3554656/page57
This will lock the bootloader without any trace

Many many thanks.

Is the adb relock bootloader "Code" command connected with a factory reset? Do I keep my data?

make the developer settings available, within it you will have oem bootloader authorization, you need to turn it on and theoretically ready

I reboot into bootloader and tried both "fastboot flashing unlock" and "fastboot oem unlock". None of them seems to be working. Do I have to use Mi Unlock tool?

this is a very good question! if I remember well, I read in another forum that you don't need Miunlock to just open the open bootloader in the developer settings, and then you can root it, and you just need to flash the ROM from the TWRP. to do this I think I need an OTG cable and a flash drive that you can flash, because you don't have a memory card slot

I have the same issue with the global version. I tried both "fastboot flashing unlock" and "fastboot oem unlock". I even tried Mi Unlock tool without any success. Also, they don't answer support tickets regarding unlocking the bootloader at blackshark site.
Any ideas?

Any one help me to unlock bootloader of black Shark 2 Chinese version?
