How to lock bootloader on latest stock oreo (A2017G)? - ZTE Axon 7 Questions & Answers

I am attempting to return my Axon 7 A2017G to complete stock so that I can use the warranty. I used the EDL tool to return to latest stock oreo, but it seems that there is no way to access fastboot/bootloader on this update. I've found many guides for other models or older versions on how to get fastboot but none of them seem to be specific to my model and I am not than keen on bricking my device again. Could anyone help me out on what process I should go through to be able to lock my bootloader?
This is the EDL package I flashed: A2017G_B03_OREO_FULL_EDL

I'm not even sure if you can lock the bootloader in stock+ Oreo, but it should be possible. What you can do is go back to MM (MM B10 should be fine), then use a fastboot package for MiFlash (such as A2017U_FASTBOOT_UNLOCK_EDL, it works even though you have a G) or maybe check if EDL Tool has an option to install fastboot, i don't remember.
The other way around it is not locking it and just using a modified bootloader to conceal the 5 second screen. Good enough for sending the phone with warranty. If you'll sell it you might be able to sell it for more if the bootloader is unlocked

Thanks I checked the Axon 7 Toolkit and turns out it does have fastboot unlock as part of the process of unlocking the bootloader. Though it techinically doesn't support Oreo I chose the nougat one and it still did the trick albeit with another hardbrick, once locking the bootloader I had to wait for the battery to drain again before I could get into EDL and flash back to Oreo. Very painful proccess, would not recommend, should have just used your method of going back to marshmallow locking then updating again. Thanks anyway mate, the help was much appreciated.

I never mentioned the axon7toolkit. That one is finicky, I don't recommend it. I was talking about EDL Tool (you might even find it if you google it), it's here in the ROMs, kernels, development section.

you need to flash original stock rom for your device trough edl. (rom your device came from factory,you need B11 marshmallow)
then boot into system,unlock developer options.Allow oem unlock and turn on usb debugging.Now connect phone to laptop and check the dialogue on your phone that ask for usb debug.Unplug phone.
When you did this you want to flash TWRP trough EDL.
Now boot in TWRP and flash UnlockbootloaderPackage from DrakenFX.
Reboot system.
Now turn off your device and boot into fastboot,connect your phone with laptop and open ADB terminal on your laptop or use Axon7toolkit.
In terminal enter fastboot oem lock,or in axon7toolkit choose lock bootloader.
Your bootloader is now locked.
PS: you dont need locked bootloader to recieve ota's,and make sure you are on the firmware your device came shipped with!!
You need a locked bootloader to get rid of the warning message ( dont flash any mod package that claims it delete the warning page)

Revert back to locked state after unofficial unlock (Redmi note 3 pro/SD)

Hi All, I have unlocked the bootloader the unnofical way and i am on global 7.1.7.0(LHOMICL) with twrp and root.
I now have recieved the official sms to unlock from xiaomi.
Already i had to open the phone 3 times to get into edl mode. I really dont wont to open the phone agian.
When i try to unlock the tool answers no need to unlock. I think this is because i flashed the adapted emmc_appsboot.mbn and boot.img thru fastboot.
Do i have to change te rom to another version before i try thru edl or fastboot? What is the best procedure to official unlock now because i read a lot of bricks if they try to revert back to original state.
Can some one give me a detailed guide? Thanx in advance.
You need to flash a fully stock edl ROM on top of your current setup.
This will wipe out your hacked bootloader and throw the original (still locked) one back onto your device.
Then just unlock as usual. I did the procedure myself today already as I got my unlock notification today as well.
Ok thnx for the info. I have changed this global rom 7.1.7.0 in great extend and dont wont to lose this setup.
So can I backup my current setup with twrp with the hacked bootloader.
Flash the complete global 7.1.7.0 in edl mode. Unlock with the unlock tool.
Root the rom and install twrp.
After this can i restore the backup with the hacked bootloader with twrp?
I dont know how the unlock tool of xiaomi works, so i could leave the official bootloader in place when i do the restore with twrp and only replace system and data partition or can i flash all the parts back with twrp to keep the unlock?
Wich procedure will keep the official unlock in place or will this unlock stick always?

please give a detailed tutorial how to do it. I am now in AOSP with unofficially unlocked bootloader. How to relock it again to unlock officially?
Relock Bootloader
I see many asking how to Relock Bootloader, especially those who had unlocked unofficially.
The steps to be followed are following:
(1) Turn on USB debugging for your phone;
Go to Settings -- About Phone --> Touch 7 times on "MIUI version" to Enable Developer Options.
Now go to Settings - Additional Settings - Developer Options --> USB debugging.
Enable USB Debugging and Connect to PC.
(2) Download Fastboot ROM (file extension .tgz or .tar) from
Code:
http://en.miui.com/a-234.html
(3) Boot into EDL
adb devices (to check it's connected)
adb reboot edl
(4) Use MI Flash Tool to Flash the Fastboot ROM
PS: It is assumed that person knows how to get drivers installed for phone if not already, use ADB command as well as know MI Flash Tool basics.
@BRoy_98 @ioosis @davegrond : hope this helps.
@MrColdbird Thanks for the tip

On MiFlash, select folder of Fastboot ROM, then click on Advanced, and in fastboot script select flash_all_lock.bat. After it, close MiFlash then open it again and check in advanced if flash_all_lock.bat comes selected. If yes, close advanced box and flash ROM. Don't forget to close and open MiFlash after choose flash_all_lock.bat script, it's important step. And you can do it in Fastboot mode, don't need to go to EDL mode to flash the ROM.

warranty
does rooting redmi note 3 void warranty bcuz it has a locked bootloader and cannot root without unlocking it ????
and can we lock bootloader again for warranty claims ????
plzz help ???
ty.
Why can't we directly update the device..
Like after flashing miui ROM (7.1)then installing (8.1)....will the bootloader get locked....
?....somebody have any idea place help out
Q. Can the device be rooted without voiding warranty?
A. Yes, by unlocking the BL unofficially.
Q. Once rooted and on MiUI, can I update using Updater?
A. No! You'll lock your BL and end up in a bootloop. Instead, use the updater to download the zip file, reboot into recovery (TWRP or ZCX) flash the zip first and then the universal boot.img patched/lazy flasher and reboot to system.
I followed the method mentioned in the replies to relock the bootloader, i.e, flashed the fastboot rom in edl mode
But for some strange reason, when I entered the fastboot mode and checked whether the bootloader is locked or not by "fastboot oem device-info", it said "Device Unlocked: True"
The main problem came when I booted into the ROM; It broke all kinds of wireless connections. The wifi malfunctioned, the phone wouldn't read the SIM cards etc.
Is there a solution? Please help
Thanks

Can't unlock bootloader, can't finish OS setup

So I upgraded to Nougat on my P9 Lite, unlocked boot loader, used twrp, flashed roms and everything went smooth. Saw a more up-to-date version with no bugs, so I had to downgrade to MM first.
I followed a guide, but I messed up somewhere and ended up having my bootloader locked, and I can't access the OS to enable developer options and oem unlock from settings. The reason why I can't access the OS is that I am stuck in the setup. I am stuck at the part where I have to sign in to my google account. It doesn't show a keyboard, only a microphone, and I can't use that for my password (it won't let me).
Any ideas?
TL;DR messed up during downgrading from Nougat to MM, now TWLR is gone, bootloader is locked and my main issue is that when I get to the google account sign in part during OS setup, there is no keyboard (I can only use dictation) so I can't sign in... So I'm stuck
Also, can I unlock bootloader without access to OS, without being able to navigate to settings, enable developer options and then oem unlock?
1. Stuck in OS setup? Signing in to Google? Hey, it's not obligatory, can't you just skip it?
2. Flashing ROMS locked your bootloader, it's normal, but I'm sure it didn't change the "oem unlock" setting you had surely enabled before. Go to fastboot mode and check Bootloader and FRP status on the bottom of the screen. If FRP is unlocked, you will be able to unlock bootloader again.
3. If you have your TWRP gone (flashed by stock ROM), flash the recovery partition manually - fastboot flash recovery TWRP.img (download from Meticulus Project site).

It is obligatory, I couldn't skip it. I tried to use other methods of signing in, but then it asked me to reset password at the end.
Both Phone and FRP are locked
I think I have missed this, but I can't do it via fastboot because I keep getting "Command not allowed" whenever I try to unlock bootloader or do anything via fast boot.
Also, thank you so much for your time and input. It is much appreciated.
That's weird, I flashed my phone several times with different ROMS (not Nougat) and this setting (oem unlock / FRP unlocked) stayed enabled. Don't know where it sits then and how to change it without getting inside OS. But - what about TWRP? Oh right, you won't be able to flash it without unlocked bootloader... Oh, crap. I would try SRK Tool for Huawei to play with bootloader, it uses fastboot so shouldn't help, but maybe, just maybe? Maybe try flashing whole ROMs through dload folder on SD? Stock 120, 161, Nougat, I would try these. I hope there is some way to unlock FRP, probably it's possible in DC-unlocker (it's a paid software).

Yes, it's very weird. I haven't done the process a lot. But I've flashed a couple of phones I had before, went smooth. Nothing major like this happened before.
I will consider the SRK Tool and I did not know about the DC-Unlocker tool, thank you for telling me about it.
Flashing whole roms through dload folder only works with Nougat for some reason, and I keep getting stuck in the signing in problem because of no keyboard, someone told me that's incomplete software, I'm hoping that's the case, any ideas where can I get it from?
Again thank you Jagiel88 for your time and advice xD
No problem, unfortunately I haven't tried Nougat yet, so search for help on down/upgrade Nougat beta <-> Marshmallow threads .

Cannot get into fastboot

Hey guys, I have a unlocked, rooted phone which i need to return to ZTE. I used miiflash to get back stock rom and recovery but need to lock the bootloader. Whenever I try to go into fastboot mode, the phone just sits in the "Please lock the bootloader" screen, but i can get into stock recvoery and the ROM starts.
Even using adb or stock recovery to go to fastboot doesnt work.
I used this package to flash stock:
ZTE_A2017UV1.1.0B32_FULL_EDL_PACKAGE_BY_TURKDEVS
Any ideas?

That's normal. I think there's a package called A2017U_FASTBOOT_UNLOCK_EDL somewhere over here (they got it from 4PDA). Flash it via MiFlash and it should slap a new bootloader there or something. After that you can lock it
Ok just to verify, i am on the B32 stock rom with the bootloader still unlocked using Miflash, i need to be very careful doing this as I have already bricked one phone this week (another thread is coming about that)
i should use this thread to go back to B29 then lock the bootloader?

I believe B32 doesn't let you access the Bootloader. You need to MiFlash B15 in edl. Then you'll be able to access the Bootloader and fastboot oem lock. But be patient it takes over 30 mins for it to completely flash the package. After you relock it then you can either ota back up, MiFlash B32 in edl, or install the official b32 zip from zte from the SD card.
Here's B15 edl package

Turn off your phone completely, then hold volume up, volume down and power at the same time. You'll see the LED flash red once and nothing on the screen. That means it's in EDL mode. Connect USB and your computer will recognize it and do as you wish

First time I downgrade from B35 to B29, then to B15. Took a while. 2nd time, I found a TWRP EDL file which gives you twrp and fastboot altogether. https://build.nethunter.com/misc/axon7/A2017U_B29_TWRP_EDL.zip

Cannot get to bootloader mode after installing stock

I've been using custom ROMs for a while on my A2017G but decided to get back to stock. Before doing all the bootloader unlocking/rooting etc I backed up my original firmware (Nougat, B09). So I reinstalled the original firmware that I had backed up but somehow lost TWRP in the process (the bootloader is still unlocked). I then used Axon 7 Toolkit to re-install TWRP. Unfortunately I cannot get to bootloader mode through Android Recovery as it reboots normally. Axon 7 toolkit gives me the following notice 'If your device rebooted normally then your device has no access to fastboot. Follow the miflash instructions for the bootloader unlock option to restore your device's fastboot mode'. The thing is the phone is bootloader unlocked so I don't need to unlock again.
Basically, I cannot install TWRP through bootloader mode. I also tried adb-fastboot tool from my Pc but same thing happens, phone reboots normally.
What I really wanted is bring back the phone to full stock, including re-locking the bootloader.
I also want to have the bootloader re-locked again before selling the phone.
Any help/ suggestions much appreciated.
Good lord, don't use the Q&A mode for a simple question. XDA Labs opens it on a browser window
Follow Controllerboy's guide, but only the part where he installs TWRP with axon7tool. After that, boot into TWRP and follow raystef66's guide on how to get rid of the 5 seconds screen. That'll give you fastboot. Then flash a full stock system, stock recovery, and you'll probably be safe enough to relock
But I'd ask the next owner if he/sge actually cared on having the bootloader unlocked. Relocking it is risky as $hit you know.
Sorry, am kind of new and was not sure which way to post my comment. Thank you for responding and the advice. I managed to install full stock, actually downgraded to Marshmallow so I can get to fastboot/bootloader mode now. Thanks again.
You can still have bootloader mode on Nougat if you follow raystef66's guide. Plus it will hide the 5 secs screen
Actually I discovered I can't get into Fastboot mode from stock marshmallow so guess it's back to nougat with raystef66's guide.

No fastboot, unlocked bootloader, oreo 8.0 cant root and install drm fix or TA

Hi guys this is a strange issue, i was on omni rom 8.1, (unlocked bootloader, got my ta backup) and i though i just go back to stock, i flashed stock oreo 8.0 34.4.A.2.32, when i try to flash boot_32.img i got a bootloop, and i cant enter fastboot because light turns green, SOmmc flash device shows up in device manager, but i can easily flash any firmware i want with flashtool.pc companion says i cant fix firmware because of unlocked bootloader. Need a little help here :/ i can go back to omnirom 8.1 which i dont really like yet or to stock rom but with bad camera....
p.s i can easily enter fastboot through: adb reboot bootloader ... but i need to get to fastboot with phone already off to root. i tried different adb fastboot drivers, disable drivers signature, nothing works much...
Can i somehow flash tabackup.img without fastboot and root on stock oreo?
Edit: managed to get to fastboot.... it was volume up on my device somehow................
