Please help! ZTE Axon 7 won't boot after deleting Lineage and TRWP

Hi,
don't know if this problem has already occurred before.
I had lineage and TRWP installed on my Axon 7 (EU version) and wanted to go back to the stock a2017g.
Therefore I deleted the ROM and wiped everything with TWRP.
Then I deleted TWRP and now i'm stuck at the the bootloader (which is unlocked), but TWRP seems to be gone.
The main problem is, whenever I try to flash a new stock rom (via recovery), I get the error "signature verification failed" and the process is aborted with no change to the system whatsoever.
Is there anything I can do at this point or is my phone practically dead?
Thanks in advance for any help.

Try to boot into bootloader interface, and issue command "fastboot flash recovery TWRP.img" on your computer( the current working directory should contain the TWRP.img file) . If your bootloader is unlocked, you should see no error of this command. Then press up/down button to select recovery mode. You should see the familiar TWRP again. Good luck!

Did you try flashing an official full zip, like B10? That's another thing you can try, since you're going to lose TWRP after you flash a stock rom anyways

If you dont have recovery, flash it from edl mode, you can flash twrp or stock.
Once you install it, performa a full wipe from stock recovery, and flash a full zip.
I have similar problems, I dont loose recovery, but stock dont boot after coming back from aosp, a factory reset did the job. I think is because different filesystems in data partition

Hi, the B10 ROM from the ZTE homepage did the trick.
Worked out nicely.
Thank you so much.
One final question remains for myself: How can I relock the bootloader (so that the 5 second screen won't show up at the start).
Tried different ways with adb and fastload, but nothing seemed to have an effect here.
So what to do?
Thank you again for your help.

you shouldn't. Fastboot should do the trick, by doing fastboot oem lock, but many people reported bricking and bad stuff...
Actually that screen comes very handy in case of a brick or if you want to enter a specific mode.l, you just select the mode and voila
Do you have fastboot? I don't know if B10 still has it, but 7.0 hasn't got it

Hi,
I tried adb and fastboot via pc and with the axon toolkit.
The adb worked fine, but no sign of effect by the fastboot commands.
So I guess I don't have it.
Is there any other solution to at least bypass the 5 second screen?
Thanks

Lol fastboot is not something like EDL, it looks similar to the 5 sec screen...
When you get the 5 sec screen, use the vol keys and pwr to get to the Fastboot option and enter - it should reboot and get to fastboot after some time
You should look up what fastboot, EDL, ADB and DFU are before doing all this stuff - you can mess up badly, and by not knowing you're complicating everything - my explanation and your understanding

[HELP] Device only boots/reboots to TWRP, can't access Android anymore

I'm with unlocked bootloader and Stock ROM. Did only two modifications, installed TWRP and then rooted my device.
An OTA update showed and I clicked yes, it rebooted into TWRP and now I can't boot normally anymore!
Even flashed some custom ROMs, but still, TWRP only reboot to itself.
How can I restore Stock ROM? or any other ROM??

Hey bud. Flash the stock ROM from forum boot it up and you'll be ready to go flash crazy

Enter into bootloader mode, connect your phone to the PC and use "fastboot continue" command in ADB.

I had the same issue when I installed an OTA update on my G5 S Plus. The command made it boot up with no issues. Thank you so much.

P9 lite Bootloop, can't update with 3 button method.

I recently tried to downgrade my phone from nougat to marshmallow but when I flashed the downgrade package it rebooted and now the phone is Bootlooping. I can't flash any other firmware because I am unable to enter recovery. I can enter fastboot though. Please I need help to restore my phone.

Hi,
Please read my repli HERE and try it.

Unlock your bootloader even if it says it's unlocked.

Sadly I tried flashing multiple system .img and TWRP .img with no luck. The phone ran out of battery and it won't even charge, it goes straight to a screen that says "Your Phone Has Been Unlocked and can not be trusted, etc" I'm completely at a loss.

Ok, your bootloader is unlocked and the black screen with red warning is normal.
Find a recovery for you actual buggy version (Nougat?).
Boot on bootloader and use ADB command:
"fastboot flash recovery recovery.img"
And past the return here.

That's what I did. Turns out the phone was out of battery that's why it wouldn't Boot into recovery. I followed the guide mentioned above and then phone is working flawlessly once again. Thank you all for your time and help!

Without commands

Hello, I have an issue with TWRP.
When I reboot to system the next time that I want to enter recovery the phone doesn't enter to recovery, but after flashing it, it does. It says "Without Commands" instead of enter to TWRP. I tried to enter in it on fastboot mode. I installed TWRP 3.2.1 with 3.0.1 Vache.
And yes I already have unlocked the bootloader, I'm on November 1st security patch without root.
What can I do?
Regards to everyone :laugh:

Are you sure that the command you used was fastboot flash recovery twrpxxx.img? Also kingroot pc sometimes tries to install a custom recovery, it got rid of my stock recovery like that.

Moto g4 plus recovery boot loop...

Hi guys. Few days ago I unlocked the bootloader of my Moto G4 plus, install twrp recovery and root the phone. Then I made the mistake of trying to install an update from OTA and since that day it is impossible to start the phone normally. It always starts in recovery mode, then I must go to restart to start in fastboot mode and next, select start to be able to use it. I reinstall the latest version of the recovery twrp and the ROM of LineageOS but nothing changes. Can someone tell me if there is any console command I can execute in the phone to start normally?
Thanks for your time...

Thanks for your answer. I don't understand the reference. I can flash any firmware without problem.
I looking for a commands to repair the boot because I have a boot loop with recovery mode.
I can use the phone but only across: recovery > restart > bootloader this restart in fastboot mode, next I select "start" And the phone boot with Android....
I whant to start in Android directly... I whant (if exists) any console command or any solution to fix the boot problem.

Oh, then you can try using these commands through fastboot:
mfastboot oem fb_mode_set
mfastboot oem fb_mode_clear
