Getting a "please lock the bootloader" message on boot

Hey guys.
I have the A2017G B04 (TWRP, unlocked bootloader, CM13) and I tried switching to DrakenFX's A2017UV1.1.0B15. I flashed both the bootstack and the systemstock on my phone but now every time I boot my phone gets this message:
< More options
press VOLUME keys
Your device software can't be
checked for corruption. Please lock the bootloader
Visit this link on another device:
g.co/ABHg.co/placeholder
If no key pressed:
Your device will boot in 5 seconds.
The volume buttons don't do anything. What do I do? I tried re-flashing CM13, wiping, wiping system, wiping davlik (not neccessarily in that ordeer but in different combinations).
What do I do?
Thanks in advance.

Don't do anything. It's normal, happens when you unlock your bootloader. Just wait 5 seconds and it'll boot.

Oh.
Well it doesn't boot after 5 seconds, it just doesn't let me do anything. When I click the power button it just shows me a black screen with linux's penguin. All I have is the options: Recovery, power off & restart are obviously useless and fastboot mode just enters fastboot mode.

The issue might be that you tried to flash the entire A2017U system and bootstack on a A2017G. Last I checked, that didn't work.
Boot into fastboot, connect to your PC and flash TWRP, boot into TWRP and flash the bootstack and modem for your model (grab from the LOS 14.1 thread). Then flash either just systemstock for ZTE's stock Nougat, or flash LOS 14.1.

Thank you so much! That worked, I'm running LOS and switching to A2017G B09 as we speak!

I have the same problem and fixed it!

What you need:
-A computer
-Axon7toolkit
-MiFlash
What to do:
Select your model then you will see a list of options. select option 10 and press OK. then wait for the recovery to download. MiFlash will open and Instructions.txt.
In MiFlash press select, then select this PC>Local disk (C: )>Axon7Development>Axon7Toolkit>MiFlash>B10.
Then press OK and then Flash. when It's done hold the power button until you feel a vibration. Then wait for it to boot, It might take 2 minutes to hide the ZTE logo. then you will see the boot animation. You will have to wait a while for the AXON splash screen to dissapear.
Just setup your phone and you're done!
Done.
Reply If it worked and make my thanks meter go up by one.

Did you read this thread at all? That message is normal. It's the bootloader boot splash.

HELP Soft Bricked A2017U

The issue I am having is that I wanted to set my phone back to factory, after I relocked the bootloader my phone when booting(with or without the volume keys) would shut off right after showing the ZTE boot screen. Now when I connect it, it shows up as HS-USB QDLoader 9008 (COM5)..
Ive been looking at these two forums similar to my problem:
https://forum.xda-developers.com/axon-7/help/bricked-a2017u-t3573798
https://forum.xda-developers.com/axon-7/help/a2017g-totally-bricked-t3537990
I understand I should use the axon7tool(When I try "axon7tool -r boot" i get failed to connect) , but I dont know exactly what I am doing.. I apologize for me being so dumb about this but if someone could please spell out exactly what I would have to do, to get my phone back to factory settings. Any help would be greatly appreciated.
RECAP: Bootloader locked, shows up as HS-USB QDLoader 9008 (COM5), It did have TWRP.
EDIT: When trying MiFlash, I get a ERROR_BAD_FORMAT 0

I just did the exact same thing you did and had the same issue. What worked for me was downloading the factory image from ZTE, putting it on an SD card, going into stock recovery (vol up + power) and select apply update from sd card. The file you download from ZTE is double zipped, so make sure to extract the update.zip file from the parent zip before you put it on the SD card. It will be in a folder with the same parent zip name. I no longer can boot into bootloader from stock recovery (not sure if that's normal), but at least my phone works again. Here's the link.

Hope this helps.
EDIT: I also had TWRP when I locked my bootloader, so I'm assuming you're able to get to stock recovery with volume up + power.

Doesnt let me boot into anything.. Not sure how I screwed it up this badly. Im trying a MiFlash method right now to see if it helps

what happens when you hold down volume up and power button at the same time? you should feel a vibrate and when you let go, you should see the stock recovery.

No, Just shuts off after the ZTE logo pops up

The phone might still be on at that point. When the ZTE logo would pop up for a split second for me, MiFlash was able to see the phone. What happens when you just hold the power button for about 10 seconds right after the screen goes off? Does it stay off?

I believe you are right, when the logo isnt up(after it disappears) that is when it connects as the COM5 otherwise when the logo pops up it disconnects the resumes the cycle.

so if I hold it, it just keeps showing the ZTE logo then shutting off

Just to clarify, holding down both the volume up and power button simultaneously at the same time for at least 3-5 seconds after the phone is off (not after the screen goes blank after the ZTE logo) still gives the same result as if you just pressed the power button?

Yes.

If MiFlash can see the phone, maybe you can unlock the bootloader again?

exact same problem as you, except MiFlash successfully flashes B19 but it still doesn't boot

What you need is FLASH stock recovery in EDL Mode.
That will fix your problem..
P.S. as soon you boot your device after Flashing stock recovery ,will perform a factory reset.

You should download YOUR variant SDCARD UPDATE zip and flash using stock recovery.

"E:failed to map file, Installation Aborted"
I have not tried to flash a redownloaded version of B15 because I cannot move the file onto my sd card. I was able to flash a signed twrp on locked bootloader before to enable MTP, but whenever I flash a signed twrp now, I just get stuck on zte screen. Why is this phone so inconsistent?

Cant boot into TWRP

Hello, ive unlocked my bootloader on my h870 and ive flashed twrp. when ive just flashed it i was able to boot into twrp but now everytime i try to boot into it it wil wipe all my data with the stock lg recovery mode can someoneone please help me? Thanks! Just got the phone a few hours ago

You have to install a custom rom or root to make twrp permanent, if you don't do that it will install always after the first boot the stock recovery.

You need to reflash twrp with the bootloader like the first time.

When you have flashed twrp, you do the buton combination to enter twrp, if you fail to enter twrp a the phone boots into system the stock recovery will be reflashed so you have to reflash twrp.
Try making these:
When you are in the bootloader after flashing twrp press button down+ power button. When the screen turns off quickly stop pressing power button and quickly press again until the lg logo appear.
When the lg logo appear stop pressing power button, quickly press again and stop pressing the power button and press again quickly until you see twrp logo.
These method works for me for booting twrp easily

The stock recovery appears but you have to select the factory reset option and it will boot into TWRP

Unfortunately still not succeeded after trying all the solutions i've found here

Hey, i have the same Problem, my TWRP broke, i can't boot into recovery and my Device ist not listed in fastboot mode. Can someone help me out?
I get the ring in windows when i plugin but its not recognizing.. Can someone pls help me out?

Okay, I'm going to try to explain it, and see if I can succeed where others have not.
You install TWRP by booting to bootloader and using fastboot to push a new recovery:
Code:
fastboot flash recovery twrp.img
It seems like you accomplished that successfully. The next step is to immediately boot to recovery; do not boot the phone to system first. You will get the factory prompts for wiping data, but it will not actually wipe your data this time. Instead it will boot to TWRP.
Now, while you are in TWRP, you need to either root (flash Magisk) or install a custom ROM. If you do not, your next boot to system will remove TWRP and restore the stock recovery. If that happens, then the data-wiping prompts the next time you boot to recovery are real and the phone will wipe. So you MUST - must must must - root or install a custom ROM while you have TWRP up, in order for TWRP to persist.
If you have already experienced this problem, you need to start over at the beginning; flash TWRP again, and then follow the rest of these directions.
Maybe this will help clear up the problem for you guys.

Oh my god, i really really thanks for your reply, you're so fre*king good. U made my day.

Guys a little help
I only manage to see the TWRP welcome screen and the the phone automatically reboots to system
I can't get to see the TWRP menu at all!!
WTF is going on?
I have repeated the process many many times and always the same. What i am missing here?!?!?

me too when it boots in twrp only showing logo then it reboots in system what are wedoing wrong?

Got the same problem. I unlocked Bootloader, checked if unlocked (yes). After flashing TWRP i see the TeamWin Screen and phone boot again. There is no TeamWin Menu.
A try with an older TWRP-Version and flashing via fastboot with another PC does not work too.
Anybody an idea?

Did you guys manage to fix it?
Matt.

With 3.2.1.0, 3.2.2.0 and 3.2.3.0 it only briefly shows the TWRP screen and then boots into system anyway.
With 3.1.1.0 the key combination to boot into TWRP as with the other versions above simply doesn't work, again it directly boots into system without even showing the TWRP screen.
I'm stuck with a resetted phone because of this bull****, because some instructions said "oh, the reset dialog will not really reset your data..." - yeah thanks for nothing, buddy.
So what now?
EDIT: I got it working using TWRP 3.1.1.0, but the same version from the OFFICIAL site didn't work, as I described above.
The only 3.1.1.0 TWRP that works with my phone is the one from this Link: http://downloads.codefi.re/rashed/g6/
(which is linked ... somewhere here in the Forum, don't remember which thread)

What Have I done.... Soft Bricked A7G

Hello All
I have problem with my Axon7 G. I had 8.00 version installed and tried to make a system write option with using a method mentioned in
Official (Beta) Android 8.0.0 V1.30B01 EU Version by NFound thread. I flashed zip mentioned in this tread -ZTE_A7_UniversalBootStack.
Then restart devices and...whats happened....soft (or hard) bricked my phone!!!!!
1. After restart i had a standard warning about unlocked bootloader with yellow fonts . After 5 sec yellow fonts changed into red and wrote my device is corrupt...
2 using vol down i can enter into bootloader mode - then i can choose option like fastboot, recovery,restart and power off.
- pressing recovery and restrt , phone restart and again boot into bootloader mode with option above (cant get into twrp or stock recovery mode)
-pressing fastboot i can enter into this mode .
3 . Use fastboot mode to flash recovery and boot ( fastboot flash recovery recovery.img and fastboot flash boot boot.img)
everything seems ok but...nothing changed , i cant boot into recovery -twrp or stock. Still go back after restart to bootloader menu
4. edl mode.....i can`t enter . Use vol + and vol- and power button then after 3 sec phone went black screen with red light upper left. Applications cant recognize phone in this mode...
somene can help me ???

I also get the warning but I can just continue with the boot. I can't access recovery however. Don't know hot to fix that.

Ok I did this. A7 is working )
I flashed this via fastboot flash file: A2017G_B06_NOUGAT_STOCK_FASTBOOT_EDL.zip then i went into twrp and everything works

did you manage to get the error message away?
I got it recently after installing LOS 15.1, but for me everything works fine .
I'm just afraid if the device randomly reboots at night my alarm won't go off in the morning since it's the device is shutting itself down after the 30 second warning.
If you've fixed this can you please detail me through the steps.

stuck in BootLoop

Hello i installed on my Rooted and Bootloader Unlocked Oneplus 6t the pixlify module
Then i clicked restart and now i can only see the Dark Google Boot animation
I Already Tried :
Turning off (restart) while pressing power and volume up to go intop Recovery (TWRP)
Its just not working i cant get into twrp
What happens Exactly after i pressed : power and volume up
Phone restarts
I see the Bootloader Warning
And then again the Boot Animation

Volume up + Power combination boots into bootloader not recovery, recovery combination is Volume down + Power.
Anyway you can't even boot to bootloader? Or it restarts after booting to bootloader?

You need to delete this module, you shouldn't install any magisk module without reading what they do or how they work.
It's perfectly stated in the repo that pixelfy isn't for OOS (Oxygen OS).
You need to boot into TWRP recovery, If your device is detected on your PC try adb reboot recovery
Or if it's detected in fastboot/bootloader then use fastboot boot twrp.img (Replace twrp.img with your image location and name)
If it's not detected try fastboot continue (You may have to spam this command for a couple of times)
Note: To run these commands you may want to install your device specific driver and adb tools. You can get the driver from here.
If you successfully booted into TWRP then flash pixelify zip again to completely uninstall it.
