How to re-lock bootlader

Here you can find several full ROMs, there is even a 7.1.1 one (GRIFFIN_NPL26.118-20) as well:

Not sure which channel though.

Now I see that you linked the most current version (NPL26.118-20-5) with september patch.
Do you think I can safely flash this to my locked unrooted reteu XT1650-03?

Yes you can. I managed to relock the bootloader.

I don't think so.

Code:

C:\adb>fastboot flash boot boot.img
target reported max download size of 536870912 bytes
sending 'boot' (32768 KB)...
OKAY [  0.970s]
writing 'boot'...
(bootloader) Image signed with key bad key
OKAY [  0.832s]
finished. total time: 1.801s

Code:

C:\adb>fastboot oem lock
...
(bootloader) Still require signed boot.img
OKAY [  0.003s]
finished. total time: 0.003s

Wich boot.img are you trying?
Is it possible to send it to me?
I downloaded the rom from another side because from official motorola it is saying I need to be logged it.
While flashing it is saying that it is a security downgrade and boot cant be verified.

I tried this image:
GRIFFIN_NPL26.118-20-5_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml (September 2017)
and I managed to lock the bootloader.

Dëmön_1 · Oct 19, 2017

I have done it.
The bootloader is locked and phone working.
I needed to do some steps.
The first time the bootloader was locked but the phone was only starting to fastboot, no normal boot was possible.
I unlocked the bootloader again and flashed the NPL26.118-20-5 rom again but this time without locking.
Let the phone boot complete until I could use it.
Now again into fastboot mode and flashed only boot.img, oem.img and all systemchunks, without erasing anything.
Locked the bootloader with "fastboot oem lock" and it worked.
Bootloader is closed.

EDIT:
I forgot to say something.
The rom I used was this: https://rsdsecure-cloud.motorola.co...ubsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
Today I could not only start the download it was completly downloaded.

Any chance you could be so kind as to rehost the zip somewhere like androidfilehost? I have to return my Z tomorrow (bluetooth is and was always totally broken) and I'd like to return it stock/locked if possible to avoid getting charged unfairly. Appreciate all the work you've done

*** edit - nevermind - if you google the zip name, there are some google plus pages that have links to the same moto URL - but they work, presumably the referrer links are whitelisted somehow. Will be giving this a try in a min!

Please let us know that after this reflash your battery consumption/SoT got any better than before.
Thanks.

Please also let us know if your bt problem has solved by the reflash.

BTW what model/region do you have?

Sure - the first attempt just now failed. I skipped the initial instructions, in that I omitted the 'fastboot oem lock' steps, and went right to your second step from post #26. Let it boot to setup, then exited back to fastboot, and did boot.img/oem.img/chunks/oem lock. Still got the 'untrusted' loading screen.

I have xt1650-03 united states GSM unlocked. Nothing has fixed bluetooth - it's screwed. Had the issue I found in several searches - the bluetooth settings page never finds any devices, and no devices can find the moto. The "scanning" wheel never turns. Disabling location scanning didn't help, nor did safe mode. Cache clearing via settings->apps, or TWRP didn't work. Flashing roms didn't work. I even got some 7.12 Bluetooth Sharing/BluetoothMidi apks and painstakingly set those up as system apps. No dice. Hardware problem, clearly, and I wasn't willing to go without bluetooth.

I'm trying the process again, this time going through the full flash instructions, then the flash without locking, then the step from #26 where you flashed some images and locked. Will see if that helps.

One other note - clogo has failed to flash each time I've tried to do it:

erasing 'clogo'...
(bootloader) Permission denied
FAILED (remote failure)

no luck with the second go round either. could it be because I have bootloader version 91.07?

Dëmön_1 · Jul 9, 2014 29 8 0

Was is possible for you to lock the bootloader at all?
I could lock it at first try already but then the phone didnt want to boot at all - only to fastboot with the error "couldnt verify and use the software repair program on computer to fix it".
The bootloader was for sure locked but the phone not working.

I made some tests while I was at it.
I tried directly fastboot oem lock but of course the error was "still need signed boot".
flashed boot - now with fastboot oem lock I got "still need oem and/or system - key bad key"
At this point I did it like I have written in #26.
I could see that flashing boot seems to work.
I tried the other day with a zip downloaded from other place.
With the other rom it didnt work at all and trying flashing boot the error was "security downgrade". It should have been 20-5 but I think it wasnt.

Since bootloader lock the phone passes safetynet directly.

Do you have any improvement in battery consumption since the reflash, or is it the same as before?

Hi guys,
I want to return to stock and the relock the boot loader on my Moto z.
Actually i am using the resurrection remix custom rom.
Which steps do i have to follow to return to stock and relock?
I downloaded the firmware "GRIFFIN_NPL26.118-20-5_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip".
Do i just have to flash this rom with fast boot and everything is fine, or do i have to follow other steps?
Thanks in advance for your reply.

Flash should be enough, check Demon's post.

Thanks.
I just read his post and downloaded the firmware version from there.
So I will try his steps and see if it is working.

Just a short report of my progress:
Got my bootloader relocked. Followed post #26 and this did the trick:
Full flash of the stock rom.
Boot up the stock rom and do the inital android setup.
Reboot to bootloader.
Run "fastboot oem lock" it tells you to run and the command a second time so
Run "fastboot oem lock" again
Flash boot.img
Flash oem.img
Flash all sparsechunks
Run "fastboot oem lock"
Then the phone rebooted with a relocked bootloader into the android system.
Thanks a lot for this tutorial

matonka007 · Nov 6, 2017 at 4:10 PM

Did the same as in #26 post and everything working now! This is only one working solution. Tried many other guides and nothing helps. Great. Now I have locked BL again and everything working
