clarify ota updates & root

Hi all
I searched this, but I question here,
1 - When you unroot , put stock and update an ota, it blocks the bootloader?
2 - and the when unlocked, format all to factory?
3 - In what moment the bootloader is blocked? only when first unlock is done?
Thanks in advance, I have an honor 7 and I Know how it works, but this honor 8 L09?

1. probably
2. u can prevent factory reset if unlocked earlier
3. idk what the question means

3 - well, the main question is if in every ota update , it locks the boootloader and when unlock, format all ...this is the main question
in honor 7, I unroot, apply the ota and root again with no problems

lock bootloader i can't tell, if it does u can unlock the bootloader and again, and straight after flash TWRP it won't wipe the internal SD

Hi. bought an al-10 from china which apparently is flashed. There are a few things not working on phone so apart from trying to get help from seller, i have attempted the flashing myself. i have gone thru a few threads and watched TK vid on flashing twrp and rooting and roni on unlocking bootloader. now, considering the device is flashed i understand the bootloader is still unlocked (in fastboot says phone unlocked). in dev options there is no OEM unlocking option. i cannot get lock state through the code in dialler. when i try to flash twrp, sending recovery OKAY, writing recovery FAILED <remote: command not allowed> so cannot really get to rooting stage
Thank you for the time.

Hi.
Sorry device is honor 8 frd-al10.
It was fastboot flash recovery twrp_cn.img
I have just received a message from seller stating it was flashed with eu firmware. I have it as frd c900b120. Should i be using the image for FRD-L09 or FRD-L19 in this case ?
Thank you.

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.

Re-lock Bootloader

Hi all,
I am trying to re-lock my bootloader, but my fastboot commands aren't working. It says "remote error command not found."
I am running stock b19 (7.1.1) unrooted. The only thing modified is the bootloader, which is unlocked.
How do I fix this error. I installed the ADB drivers. I do not know what is causing this error. Any help will be appreciated.

I think fastboot commands were disabled in b19. There's no harm in keeping it unlocked unless you're wanting to use Android Pay (in which case Magisk can hide the unlocked bootloader), or you're needing to return the phone for warranty reasons.

So I installed the factory image from ZTE's website, which uninstalled twrp and SuperSU (which I knew it would), but I am still unable to use fastboot commands. What might be causing this problem?

As far as I know you need to rollback and flash DrakenFX's fastboot command zip in order to be able to use fastboot again.

So I changed some settings in Windows Device Manager, now fastboot is working...kinda. I type "fastboot oem lock" and it hangs up for 5 seconds and gives me the error "FAILED (command write failed (Unknown error))...
I solve one problem, and another pops up... Thoughts?
EDIT: In regards to DrakenFX's fastboot command zip, where would I get that? Is it the full systemstock?

I read this guide for the Axon7 A2017G, but the zips used are for the A2017U.
https://forum.xda-developers.com/axon-7/how-to/guide-reinstall-twrp-root-update-to-t3578552
The first couple of steps restore the bootloader and get fastboot commands up and running via EDL mode.

I am currently running B29 (6.0.1). Will this still work, even though I am on a different version of Android? Or should I update to B19?

Oh...if you are on MM this should work for you.

I need to re-lock the bootloader on my A2017U. I put in a warranty repair claim with ZTE for a dead SIM2 slot. They said if I could relock it to stock, they would not charge the $79.99 out-of-warranty fee.
My only concern with the guides above is that I'm on the RR Nougat ROM. Will any of the links above work for me?

My phone it's blocked into huawei start screen

Hello,
Yesterday when I Wanting to charge the battery of my phone, it's suddenly turned off, and since it is stuck on the startup screen..
I have traveled dozens of French forums in search of a solution, I come back to you now because I am a little desperate
As for my phone, he was never rooted, and I never change firnware, I do not have access to recovery, there is only fastboot mode that works
In the fastboot mode, i can read "ap-s-abnormal-n/a et phone locked frp lock".
If I understand correctly, I can not flash my phone because it is blocked..
Please help me

Do you have Access to the huawei E-Recovery? Try doing a factory reset there.
Or try to unlock your Bootloader with ADB, Flash TWRP and then Flash a customrom or another Firmware.
I hope I was able to help you.
