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

Axon 7 (A2017G) Brick.

I had stock android 7, used the toolkit, "Unlocked" the bootloader, after that there was a part with erasing all data to factory due to an error, something along the lines there was a pin or password detected, and after I pressed reset the screen went black, and when it tries to boot it shows ZTE for a second and then it vibrates and shuts off instantly. So I can get it in to edl mode and I see the Qualcomm HS-USB QDLoader 9008 in my devices, but I can't find any thread to fix this. Tried flashing stock firmwares via MiFlash, no luck. And the thing is, most roms I download give me a batch of files in a zip, if I put them in a folder and try to flash I get this - Object reference not set to an instance of an object. Help asap, because I am having a horrible time using my partially destroyed S6 Edge Plus. If I spelled smth wrong sorry, Russian here.

This is what I had - My device is stuck on an 'Enter your password to start Android' screen.
Unfortunately this requires a factory reset.
1) Boot your device into recovery mode by pressing and holding the power and volume up buttons for 10-15 seconds.
2) Stock Recovery: Use the volume down key to go down to 'Wipe data/factory reset' and press power to select. Press the volume down key again to go down to 'Yes' and press power to select.
TWRP Recovery: Tap "Wipe" < Tap "Advanced Wipe" < Check the box next to "data" < Tap "Repair or change file system" < Tap "EXT4" < Swipe to confirm.
3) Reboot your device.

I had a similar problem on my 2017U model after flashing a .zip that was supposed to remove the "bootloader is unlocked" screen that shows up after you unlock the bootloader. Long story short, the .zip wasn't meant for U models. Only G. So my phone was in a worse situation than yours and would not power on. You'll need to download an EDL recovery firmware .zip for your phone and place it within the toolkits folders manually and then go through the steps of the toolkit which I'll try to help you do.
First, download the full stock B09 (G) firmware from here. You can OTA update to the latest firmware after a successful flash. It's okay to flash an older firmware in this situation.
Once done, navigate to C:\Axon7Development\Axon7Toolkit\MiFlash\B09\ (copy/move the full .zip of the B09 firmware you downloaded in the first step into this folder) If the B09 folder doesn't exist under \MiFlash, create it manually.
Run the toolkit again from the start and type 11 "RESTORE TO STOCK/RECOVER FROM HARDBRICK (EDL)" and hit enter. On the next screen type in the number that will restore B09. It should tell you how to put the phone in EDL mode and automatically open MiFlash. Make sure to follow the steps and paste the directory path of the firmware in the top bar in MiFlash. After you pasted it his Flash and it should successfully flash the firmware. If it gives you an error or times out, unplug the phone and try a different USB port or USB cable. It's obviously recommended you use the one that came with the phone. My first attempt at MiFlash timed out and didn't flash anything. I tried a different USB port and then it flashed.
After it flashes the firmware, leave the phone plugged in and hold down the power button for about 10 seconds until it restarts out of EDL. From there you should have a working phone again with some exceptions. It'll be on an older firmware so I would recommend booting into stock recovery and factory resetting data and wiping your cache. Then restart the phone and do an OTA update to the latest firmware. After you reach the latest firmware you can then use the toolkit for whatever you need.
Sidenote, your English is very good considering you're Russian. No need to apologize because your post had no spelling errors. :highfive:

When I type in 11 I don't have any options, it forces me to download B10, but when it tries it fails.

I haven't read what the other guy said, but basically you have to use miflash. just use my DFU unbrick guide but from the point where you short the testpad to enter EDL. But instead of opening the phone just put it in edl via adb reboot edl or holding vol+ - and inserting the cable

Did you create the B09 folder in the MiFlash directory? I also had errors downloading firmwares through the toolkit, which is why I had to do it manually and move the firmware into the proper directory for the toolkit.

After I unlocked the bootloader via the toolkit by bkores, I get a message "To start android enter your password" even though it was a stock system with no password. Like I got every possible error and solved it and now this, just why?

that's totally normal. Your internal storage is encrypted, you have to go into TWRP and format data (not wipe, format). Anyways by unlocking you lose all of your data so it's not like you lose anything
If it doesn't work, then you'll have to change the data partition's filesystem because it may be in F2FS. Change it back to ext4 if that happens

Help please can't see my phone in adb

I've had my Essential two weeks i was on 8.1 beta.Today i unlocked the boot loader.Then installed twrp while in twrp i side loaded magisk.I went back to fastboot then hit start .The phone just went into a bootloop.I Was able to go back to twrp 2 times but now i can't get back to any type of recovery.I Can get back to fastboot mode ishow all the info and secure boot says yes and device state unlocked.My pc see essential phone fastboot in the device manager but i can't get adb to see it .Can anyone help me ?

forgot something
looks like i skipped this part . Once you're in TWRP, install the stock boot image and then the Magisk/SuperSU zip.Is there anything i can do?

adb only works while phone is booted into system so nothing wrong there. If you're in the bootloader menu where you see that the status of your device is unlocked then you're already in fastboot mode. Just flash twrp again and the sideload stock 8.1 beta boot image (you can probably find it on xda), sideload magisk too. Go into install and press flash image file and find the stock boot image and then go into install again and change to flash .zip and flash magisk. After that, reboot into system.

WOW thank you so much'

No problem. Thank you very much for the donation, that was really kind of you. Hey I'm sure you'll get the hang of it before android P drops. you did figure out what went wrong all by yourself so get a hold of the right boot.img and the rest is exactly as how you did it in the first place but flash the boot.img before magisk. Let me know if you want to give it a dive again.

I'm on 8.1 boot loader unlocked and ready to try to root again .Thanks for the help

This is the closest thread i could find to what is happening to my PH-1.
Like videodave1 I 'was' running the latest stock 8.1 and have my bootloader unlocked. In trying to root the phone I did this:
flash boot flash boot twrp.img
adb shell twrp sideload
adb sideload magisk.zip
All installations went well, but when trying to reboot from twrp it forced me to install the app. After that the phone went into boot loop.
* Note how I didn't sideloaded the Oreo 8.1 image before magisk.
By pressing all 3 buttons I can get the phone to reboot and releasing the volume up I can get to Fastboot. Just volume down and power doesn't work.
The problem now is that adb and fastboot no longer recognise the phone. adb devices just gives an empty list and fastboot only shows < waiting for device >
Trying to go into Recovery mode doesn't work either. Power off doesn't work and Restart bootloader, well, restarts the bootloader.
It might be relevant to mention that I'm running adb and fastboot from Terminal in a Mac and that this is my very first and frustrated attempt to root any phone.
For reference this is what the FastBoot Mode brings:
PRODUCT_NAME - Mata
VARIANT - OPENUS
BOOTLOADER VERSION - mata-aad8ac4
BASEBAND VERSION - 2.0.C4-M1.3.1
SECURE BOOT - yes
DEVICE STATE - unlocked
I might have to just resign myself to the ordinary land of unlocked full stock phones
Thanks very much

I might be missing something hopefully obvious here. How can I flash twrp again if I my computer can't see the phone. With the USB phone plugged in and in the FastBoot screen I enter into Terminal:

How do I flash it from the FastBoot screen? BTW, going to Recovery mode just hangs at the Essential logo.

Thanks Arju. If you are referring to the FastBoot menu where you can use the up and down volume keys to select Start, Restart Bootloader, Recovery mode and Power off Yes, but not much else unfortunately.
If I select Recovery mode I don't go to the screen with the blue buttons from twrp.

What you need to understand is that twrp will not stick after you flash it. This device does not have a recovery partition and that's why you replace the boot partition with twrp and while you're in twrp you need to flash the boot.img back and whatever mods on top of that such as kernel etc.. If you flash a rom then it will replace the twrp with the boot.img found in the rom zip.
So now we need the computer to recognize you device. Could you unplug the cable and change the usb port on you computer. connect your phone while you're in the bootloader menu where it says start on the top.
The use use fastboot command: fastboot devices
See if the computer recognizes you device.

Help with loss of root/twrp

I need help! Here’s the story. Sorry for the lengthy post. TL;DR at the bottom..
- Was on B32, unlocked BL, TWRP installed, rooted with SuperSU
- Updated to B35, but lost TWRP and root (I don’t know how, but I assume I must have wiped the wrong things? - system? - I’m clearly a novice)
- Now I’m on B35 with an unlocked BL, but despite days of searching and researching, I can’t for the life of me figure out how to get TWRP reinstalled. I want to have TWRP before trying Magisk (have never used Magisk before, but would like to try it this time instead of SuperSU)
- From my Mac, using terminal, adb recognizes my devices.
- “adb reboot boot loader” gets me to a list of options “power off, restart, recovery, fastboot, back to previous page”. Choosing fastboot simply restarts the phone. What should “fastboot mode” look like?
- I tried flashing TWRP via adb while on this page and terminal stopped at “waiting for any device” and did nothing
My conclusion is that I need to downgrade to whatever latest version allows fastboot commands to work properly? Is this B15? If so, is the only available B15 zip the one that is on the ZTE website? Do I just wipe data/dalvick/cache and flash this zip?
Do I not need a Bootstock and Systemstock like @DrakenFX usually posts? That’s how I’m used to doing any updates.
Thank you all for your help, both past and present!
TL;DR: Would like to downgrade from B35 to B15 so that I can install twrp and root again. What’s the best way to do this and where can I find the appropriate files?

Thank you all for your help, both past and present!
TL;DR: Would like to downgrade from B35 to B15 so that I can install twrp and root again. What’s the best way to do this and where can I find the appropriate files?

I'm not sure where you read all that BS, but if your bootloader is unlocked then you can install TWRP via EDL (Or fastboot if you have it). No need to downgrade for anything :laugh: in the past you would have needed to downgrade in order to unlock the bootloader, now it's not even needed
Download EDL Tool by djkuz and install TWRP with that one. Or you can use axon7tool by tennear, but it's much more finicky and ran entirely by commands (no UI).
And just to avoid more trouble, DO NOT LOCK THE BOOTLOADER! You do that with the system even barely modified and you brick the phone. A bunch of people tried to do something, got scared because they made a simple correctable mistake and just locked the bootloader thinking everything would get restored to stock - doesn't work that way.
Not saying you will do this, but I've seen about 4 or 5 people that started just like you and ended up doing that

Wow, thanks so much for responding to this. Sounds like this should be easy! A couple of questions before I go about following your advice:
1). Do I download EDL Tool to my computer or phone??
2). If I'm downloading it to my computer, does it matter that I'm using a mac?
Thanks again for your help!

Oh, skipped that part. EDL Tool is a .bat. I'm pretty sure you won't be able to run it on a Mac. If you can find a Windows PC somewhere to do this, it'd be much better...
But there's another way.
Issuing "adb reboot bootloader" effectively sends you into fastboot. That list you mentioned is fastboot (if it says "Start" in green, and you can scroll that, it is fastboot). Just use fastboot from the pc: Put TWRP on the fastboot folder on the PC, then issue "fastboot flash recovery twrp.img" with "twrp.img" being whatever the twrp file name is. After that issue "fastboot reboot recovery". And as soon as you are on TWRP, DON'T GET OUT OF IT. Just wipe data, system, caches; then flash a system (e.g. b10 bootstack and stocksystem), then also flash Magisk, and THEN boot to system

"adb reboot bootloader" takes me to the start up screen that says "your device software cannot be checked for corruption..." etc. and gives you 5 sec to either press up or down on volume keys to get to list: “power off, restart, recovery, fastboot, back to previous page”, but the list is all white. If I select "fastboot" it reboots the phone and starts that cycle over again at the "your device software cannot be checked for corruption..." etc page.
Nowhere am I given a chance to use fastboot commands. I'm never on the page with the green "Start".
..This all seemed a lot simpler on my Nexus 5..
Thanks for your help/patience.

I thought you had fastboot since you described the 5 seconds screen and both are very similar. It's normal not to have it though.
I think there's some version of axon7tool for Linux but I'm not sure at all. The best way would be to find a Windows computer.
I wonder how you actually installed TWRP the first time? Via fastboot?
As soon as you get TWRP you should be able to run a few commands to get fastboot back just to have it around.

I have adb and fastboot installed on my Mac and I can't remember how I got it working on my phone in the first place, but I've only ever used a Mac for all this. Terminal recognizes my device and responds to commands until I try "fastboot flash recovery twrp.img" then it says "<waiting for any device>" and does nothing.
Thanks again for the help. I'll keep hunting though. I don't have access to any Windows computer.
Cheers

Nokia 5 unable to install Recovery

So I gave my IMEI, serial number and $5 to someone on the internet, and in return I got an email attachment to flash to my phone. So I did, and it unlocked the bootloader. Strangely enough, now I'm getting a stupid yellow message that my device is unlocked and can't be trusted, and it's a bit of a roundabout way to get into bootloader or recovery. One ONLY works with buttons, the other ONLY with adb.
Ok, never mind, so I tried installing both the 3.1.1. and 3.2.1 of TWRP custom recovery, but I am unable to boot into it to make it stick. On top of that, my phone now says "encrypted"? WTF?
Clearly this latest incarnation of Nokia is a bunch of asswipes, offering us Sophie's choice instead of just unlocking the damn things from the start, so there's no point in asking them for help, but I'd expect members here would be able to help?
Any ideas how to proceed? Is there a factory ROM somewhere? This is 7.1.2. by the way, I'm not interested in updating. Come to think of it, I hate this so-called "progress" with convoluted "security" and whatnot. Just give me the damn phone and go away, Google+Nokia. Stick your "features" up ya clacker.

1. Okk first you jeed to go this link and download official recovery for nokia 5 running android 8.1 oreo
https://drive.google.com/file/d/1Cl1...w?usp=drivesdk
2. Rename it to twrp and give the command to flash the recovery.
3. After give command fastboot flash recovery twrp.img. Give the command fastboot boot twrp.img
And boooom you enter in official twrp

Link broken. File doesn't exist

Err... no, not quite.
1. Your link is (was) dead, but in any case I'd be wary of installing something stashed in a private Google drive folder... Thanks, but no thanks.
2. I have several versions of TWRP, that's not a problem.
3. I know the correct commands (yours are not), that's not a problem.
And boom - no, you don't end up in TWRP. You end up in system, because it overwrites the TWRP automatically UNLESS you reboot to it immediately after flashing, and THIS is the problem.
It turns out that Nokia needs to be plugged into CHARGER, not the PC, then holding Vol+ and Power button combination will do it. It took me more than a dozen tries, but it worked in the end.

Hi, I had the same problem. I've unlocked bootloader and I successfully installed TWRP and I can go to recovery but the problem is I can't boot the system as it stucks on download mode. Can you help?

Press volume up+volume down+power button at the same time for 7-8 second.
