Zuk Z1: FAILED (remote: oem unlock is not allowed)

Hello everyone, I locked my smartphone and now I want it back. The only way by which I can operate it from the Fastboot mode presents the recovery of stock Cyanogen. From platform-tools, I would like to unlock the bootloader to install a TWRP recovery, but I can not because I get this message FAILED (remote: oem unlock is not allowed) when I enter this command fastboot oem unlock -i 0x2b4c. Could someone help me? Pretty much in advance.

Bro How did you solved this ?
Could you please help me.
I am stuck at the same point.

A solution would be to flash a new factory rom through the QFIL tool.

any link for QFIL ROM ?

Help! Moto E3 XT1700 stuck in bootloop after OEM unlock in fastboot..

So after booting into fastboot and using the general bootloader unlock method using the commands "fastboot oem unlock" my phone is just looping and looping. I've tried to find factory firmware images from Motorola but there is literally nothing for the E3 2016 (yet). This is a bloody nightmare as I bought the phone today and now it's unusable. I've tried flashing the TWRP version for this phone, but that also doesn't boot!
What do I do? Please help...

Use command fastboot format userdata ...

Already tried that, just wiped the whole partition clean. Unrecoverable. Just got a replacement handset. This phone is not developed upon enough yet.

help having same problem

thx solved myself with spflashtool

Follow the steps below exactly in this order:
fastboot oem unlock
fastboot flashing unlock
fastboot flash recovery twrp.img
fastboot format userdata
* it is possible that you will have to change the file name to twrp.img
If that does not help - you have to upload stock firmware [ eg. Lenovo_XT1706_MT6735M_S135_161108 ] using SP Flash Tool.

Please don`t use the newest firmware! It`s not logical, but true
Use stock lastest firmware with unlocked bootloader:
XT1700 → S124
XT1706 → S135
...and now try fastboot oem unlock, flashing unlock, flash twrp & format userdata.
Regards.

hey ,
i want to go back to stock on moto e3 power xt1706. i think i was on s146 (dec. 2017 security patch).
is it safe to flash s135. i don't want my phone dead.

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

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.

Zenfone Selfie bootloop / unlock bootloader

Hi everybody
My Zenfone Selfie after a normal update (never modified) is in bootloop.
So I installed adb and fastboot and I flashed the twrp.
Then I tried in every way to flash a rom. I've tried both with official firmware and with various versions of cyanogenmod. Through fastboot and via adb sideload.
Even if seems to work, when I reboot I get the bootloop problem again.
As far as I can understand the problem it’s that I have the bootloader still locked. The official apk solution I guees it’s not applicable in my case. By fastboot oem unlock i get an error message (probably why i can not enable usb debug).
Do you know of other ways to unlock the bootloader or in general to flick my phone?
Thanks to everyone for the help

Here is a link for selfie's boot, recovery and system images for fastboot flashing
https://mega.nz/#F!Ao1RjT7D!hQ5x60r02WveB9-Hl32B4g!810z0DoQ
You can't unlocked bootloader on fastboot. I hope you can restore your device.

i tried evrything from flashing stock image , recovery partition , boot image . but nothing works. same i dont have unlocked bootloader. i am stuck at just rebooting phone. please help

FYI: recovered G5 XT 1676 to stock and updated. :)

Just an FYI type thing that may save people a bit of digging around sometime.
I tried to get the update that just came out, but as i had TWRP as recovery, no good. Anyhow, in my trying i completely bollixed the phone. Would start, but always booted to TWRP and had various conniptions. Could not even get a TWRP backup to load. Strange not encountered before by me stuff............
Anyhow, recovered by the following method to stock and am back in business.
Boot into bootloader fastboot mode.
Extract .xml.zip format firmware file:
eg: CEDRIC_NPP25.137-15_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
to a folder on c drive of the PC that has the ADB and fastboot files in it.
In command prompt cd\ to that directory.
fastboot flash the following in sequence.
fastboot flash partition gpt.bin
fastboot flash motoboot motoboot.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk1
fastboot flash system system.img_sparsechunk2
fastboot flash system system.img_sparsechunk3
fastboot flash system system.img_sparsechunk4
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot reboot
boots to stock .

After this, Motorola system update installed. On Australian XT1676 is build number NPP25.137-15-7
Patch level 1-May-2017
Still get the I cant be trusted page on power up as have unlocked bootloader.
Many thanks to all at XDA, its a resource that can certainly get you into trouble, but then out of it again.

where do you get the stock firmware?

Think I worked out what I did wrong. Somehow, I changed the format of the data partition. Fat fingers at some point??
TWRP backups didn’t like that and would not mount or write to the data partition as it was not f2fs format that the backup had been made in??
Anyway, restored data from a TWRP backup after going to ....wipe…format data. All good.
That gave me the passcode lockout issue at next reboot which can deal with.

We're you able to revert to a locked bootloader after this, I am looking forward to do so

didnt try, didnt need to for taking take the update.
And, from my reading there is no way so far to relock the bootloader. I got it to stock, with stock recovery, and that was enough for me.

You can get rid of that easily
Put phone in fastboot mode
Download logo from link below
Enter the following in a windows command prompt where you have fastboot files & the logo file
Code:
fastboot.exe flash logo logo-g5-fix.bin

downgrade
thanks for the guide
- can i use this method to downgrade to this version?
- can i do this without unlocking the bootloader
- if it goes wrong can i unlock the bootloader later (i have an unlock code)
- is there a reason why we don't flash sparsechunk.0 ?
thanks in advance

No you cannot downgrade (same firmware version or newer required)
Yes - unlocked bootloader not required
As long as your phone still goes into the bootloader
You should flash all sparsechunks in number order

Thanks a bunch,
So to be absolutely clear, my phone shipped with NPP25.137-15-7 i can't install the stock rom linked, and the same version isn't out yet,
if i unlock the bootloader, would i be able to downgrade ?
Is the software channel setting preserved across this method?

You maybe able to - there are different variants of the same phone
As long as the firmware is the same or newer (as in the bootloader and API version) it may flash
It will either flash or error out
There's only one way to find out - if your phone is dead anyway it's not going to make alot of difference
No - generally you can never downgrade firmware - doing so would be dangerous and you may loose the bootloader for good

thanks again,
motoboot.img is the bootloader you talk about? is the partition layout described somewhere? would custom roms use a different one here?
do tell me by the way if i should get this information elsewhere/if i should read something to get started in the whole moto g world.

You're partially right. These commands won't work for our files. You have to flash the firmware according to the instructions contained within the "flashfile.xml" file within the archive. For example we have no "motoboot" partition

I've flashed every stock package available now (4 I think) and haven't been offered an update once. I've ran a couple of custom ROMs but they're just not right in one way or another. Might be time to move on.

I upgraded to this and since then can't downgrade the phone to the stock roms available online. From memory trying to flash gpt.bin gave a "Security version downgrade" error. So I wouldn't assume you'll be able to downgrade and until there is a copy of this particular firmware, you won't be able to flash back or relock the bootloader
