Help with loss of root/twrp - ZTE Axon 7 Questions & Answers

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?

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

Not a total Noob, but can't root!

A2017U, my second Android phone (previously had a OnePlus One, which I rooted). I have a Mac, so all the Windows and Linux tools for the Axon 7 have failed me, even with Windows in a virtual machine.
Followed these instructions and got to the point of fastboot oem unlock -> B20 again. Still not rooted. No OTA available.
Then I saw this thread but can't figure out how to flash TWRP to replace the stock recovery.
I've spent a whole day on this effort, including hours following links through threads to find files, and still no root. Can anyone please explain what to do next, in simple terms and with direct links to files?

Replied to you in the original thread.
If you already did "fastboot oem unlock", then your bootloader is unlocked.
Download TWRP, put it into the folder that your Minimal ADB & Fastboot is located in, and then do "fastboot flash recovery whatever-the-TWRP-filename-is.img". In TWRP, flash SuperSU 2.65 to root, or if you're trying to update to B29, flash DrakenFX's B29 SuperStack and System, then SuperSU 2.65.

Thank you, thank you!!!
I did this, and the phone is rooted on B29!
But one strange thing: On every reboot I get a weird boot menu with a message warning me "Your device is unlocker and cann't be trusted"
and boot will proceed in 5 seconds.
Is that normal? Is there any way to get rid of that?

Normal. If you press a volume button during that screen you can choose what you want to boot to (system, recovery, fastboot). Don't know how to get rid of it.

Looks like the same message, complete with the same spelling mistakes, happens on the OnePlus 3. I wonder who's copying who.

A2017G Bootloader mode on 7.1.1?

EDIT: Fixed! Big thanks to @S0wL , @bkores , @tamahouse02 and @tron1 for the help. I made a guide to help other people with the same problem:
Guide to get TWRP again HERE
Okay, it seems to me that I messed up kinda badly. The phone is fully operational, but after I got to 7.0 the stock recovery replaced good ol' TWRP... which left me with an unlocked bootloader and an useless recovery. I have no root, and that's pretty much the only thing that matters to me. I downloaded @bkores 's Axon7Toolkit but there is NO way to get fastboot on the damned thing. After the program tries to get to bl mode (I assume adb reboot bootloader?) the ZTE logo flashes and the unlocked BL image appears, then the phone starts as normal.
Same thing with the leaked 7.1.1, no difference.
I tried EDL, recovery, that shady factory test mode thing, no one gives fastboot... Any ideas as to why I can't get there??+
I suspect it may be something related to the OEM unlocking option in the dev options, but it is set to ON and greyed out. so no idea
Try the menu on the boot screen.

Sounds like the issue is with the ROM like it is somehow blocking you from accessing bootloader mode. It's definitely not my toolkit.

Feel the same, 7.1.1 stock recovery is evil, it keep coming back after flash twrp. LOL
Here what I didi to get twrp on 7.1.1:
1. Use axon7tool -w recovery (twrp of couse)
2. Watch closely the cmd, when it said "Successful!","Reboot in 5 second" - unplug your phone
3. Use Volume Up + Power to get to recovery (twrp)
4. Mount > Mount System (dont check read only)
5. Flash something - I don't know - But I get the feeling that it stop stock recovery coming back - I personally flash Chinese Modem (because I have to ))
6. Reboot system
@bkores Yeah I'm pretty sure it's not your toolkit since I can't access it even with key comb, adb, option on the unl bl page...
@lafester Nope, tried many times. It just boots to normal whenever I select fastboot
@tamahouse02 Well I believe that should work, but I can't get axon7tool not to crash... I'll keep trying, maybe it's a driver or sth.

Have you restart after install zadig driver?
1. From system: adb reboot edl
2. Install zadig driver
3. Hold "Volume Up + Power"
4. Enter system again: adb reboot edl
5. axon7tool -w recovery

yes, like 4 times already. I even used the stock Qualcomm COM3 drivers... no dice.
the thing is that I had to do the same when I did the stuff on android 6 and it worked after some time. I even wrote the procedure on another thread xd

Bootloader Mode is Disable/strip in G variant, and if this is how ZTE is headed to future updates it seems like U will have a Disable Bootloader Mode as well.
If you guy can rollback to MM , you can Unlock there using @bkores tool.

I was thinking about that, but does mifavor let you roll back from an SD update? I'll try later, but i doubt it.
Besides from that is there any way to flash stuff from the stock recovery? It tells me that ZIPs have to be signed only

Official 3.0.4.1
@tamahouse02
The latest "official" TWRP is at TWRP site https://twrp.me/devices/zteaxon7.html , version 3.1.0-0.
Is there any problem using it instead of the previous "official" 3.0.4.1 ?
Edit: I also read on TWRP site:
"Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install."
This is in sync with your information requiring to reboot immediately to TWRP (step 2 and 3).

I use 3.0.4.1 because I flash plenty things before without any issue, so I keep using it.
After write recovery by axon7tool, it's reboot automatically and override the recovery, that why I have to unplug to stop the reboot, and also flash all I can - fortunaeally​ it also stop recovery be overrided
@tamahouse02 sorry to ask, but is the a7tool of the link a fixed version? how does it differ from the one i have?
I've been in the same situation like you @Choose an username... Updated to nougat on G model and I had not bootloader. This is what I did :
1. Downloaded the tool from here https://forum.xda-developers.com/axon-7/development/tool-axon7toolkit-t3573108
2. Installed the driver using the install driver option that you can choose once you connect you phone to your computer
3. Use the tool to perform the unlock bootloader command again even though you have unlocked it before
4. Use the tool to install twrp, it will boot the phone in twrp
5. Flash Supersu before you boot the system first time after flashing twrp
5. Install whatever version of android want after

Unable to install TWRP

Hey guys, I'm at a lost here. I don't think I'm that stupid but I am following all steps from the guides to install TWRP without luck. I already managed to unlock my bootloader with Axon7Toolkit. I already certified that QUSB_Bulk driver is installed, I did it with Zadig, but when in EDL mode, even after killing adb, the axon7tool can't find it. I tried installing a zip with the toolkit but when I choose the package, the toolkit simply closes. Is that me? My phone?
Thank you!

What software version are you on?
I was at latest nougat but I downgraded to B10
Doing it via fastboot never fails for me.
Get to fastboot put two img in adb folder (I rename it for ease of typing since I suck) rename to recovery.img
Type this cmd in adb
Fastboot flash recovery recovery.img
Reboot to recovery and root. Done deal
download 3.1.0.0 twrp into your download folder on your desktop enter fastboot into your phone open up your command prmt type fastboot devices, your phone should appear then type fastboot flash recovery then go to the twrp right click drag it into the command prmt air page and place it there. you should see the file then hit enter. It'll take like 5 seconds it's really fast then reboot t recovery. when in twrp it'll ask you to install it again say no and uncheck the to options. DONE.
After loads of stress and bangs on the table I managed to unlock, install TWRP, LOS and root. I removed every driver related to my cell phone, deleted everything I download from it and started from scratch. I installed TWRP via fastboot but wasn't able to enter recovery mode, than I mase the stupidity to lock the bootloader back and got stuck in that password screen. Then I gave another go with the toolkit, unlocked it again and, I don't know how or why, it finally booted TWRP. Now everything is OK. Glad to be back to "Nexus mode" after so many time.
Thank you!

Unable to enter fastboot mode after flashing

I have unlocked my phone, hoping to find a fix to USB external camera not being recognized. As a consequence, I am not able to update my system through OTA. Moreover, I am no longer able to enter fastboot mode. Whatever key combination I tried, my phone will do a normal boot. When I power up or I press volume - I only end up doing a normal boot or powering off. If I press all 3 keys together I get into the e-recovery boot, which fails. I have only been able to boot into TWRP after downloading a system update and choosing to install it. With this procedure, the update will not be installed, but I will boot into TWRP. From here, if I choose recovery, I do boot into fastboot, but my fastboot is not recognized by my computer, as it was before. Running either ADB or Fastboot will not reveal any device connected.

When you use key combinations, you must shutdown your phone first, not reboot or you can boot into system, make sure that usb debugging is turned on, open adb and type "adb reboot bootloader".

Thanks, I followed your instructions but with no success. As soon as I plug into USB it will power on and go on with a normal system boot, no matter how quick I am in typing the command "adb reboot bootloader", which invariably returns "no devices/emulators found", or whether I press the volume - button or not. This also happens when I am in the charging screen (not sure whether this also equals power off).

No, you need to boot to Android to use adb.
Is your device bricked or stuck in a bootloop or something?

I wouldn’t call it properly bricked, inasmuch as it is actually doing its job. However, It does some strange things: it gets the OTA updates, but when I click on Download and Install, it restarts in the TWRP menu (which I cannot otherwise access. I have 2 TWRP apps installed, which don’t seem to be of any use: official TWRP App and TWRP Manager). When I am in the TWRP menu, I can choose to restart in the bootloader. However, once there, with the green window telling me that my phone is flashed, the phone is still not detected by ADB or Fastboot commands. I don’t know when the bootloader started to be unaccessible because I left the tinkering a couple of months ago, when I realized that nobody so far has had any success in getting a P10 Lite to work with a USB Endoscope.

I wouldn’t call it properly bricked, inasmuch as it is actually doing its job. However, It does some strange things: it gets the OTA updates, but when I click on Download and Install, it restarts in the TWRP menu (which I cannot otherwise access.

Thats normal behaviour, when you have a custom recovery installed and do anything in the stock recovery then it boots you into the custom recovery, it should also boot to TWRP when you do factory reset in the stock recovery. And when your phone isn't detected by fastboot then its probably a adb and fastboot installation issue on your PC, type "fastboot devices" to see if it detects your device. And what do you even want to do in fastboot?
Also are you in Nougat or Oreo?

I am not too sure to have any working recovery at all, right now. If I press all 3 buttons, I get into the Huawei recovery mode, which fails. I am on EMUI 5.1.1 (Nougat) and would like to install a stock recovery to Oreo. If I am able to get to a working bootloader mode, I would like to install this file which seems to be a stock recovery with Oreo (WARSAW L21C432B182_EU_SERVICE_ANDROIDHOST.RU.RAR). Otherwise, I will buy a MicroSD card reader and try copying this installation to the card, which, according to this video (https://www.youtube.com/watch?v=0vDgDXePAR4&feature=youtu.be) should be the last resort, if everything else fails. I would be perfectly happy to return to a working and updated standard EMUI. I'm told that if I installed the OTA version this would not be working correctly on my my phone. According to an app called Rootchecker, my phone is not properly rooted either, but there are a lot of crappy apps out there, so I don't know what to believe.
BTW: I don't believe there is any problem with my adb fastboot installation (on MacOS). It was working earlier on. When I type "fastboot devices", it returns: "waiting for any device"

I still can't uderstand you. Can you boot into Android or not? And Does TWRP work? When you device is softbricked, what did you do to brick it?
At one point you say that you can access fastboot by choosing reboot to bootloader in TWRP and then you say that you have no working recovery at all.
Anyway I can't help you with the fastboot thing then and that file isn't Oreo it's an old version of Nougat, B360 and up is Oreo and also B321 witch is Oreo Beta. You can only flash image files in fastboot anyway as that file needs to be unpacked and put on the dload folder on your sd card.
When you want to get to Oreo you can either use service roms from this thread https://forum.xda-developers.com/p10-lite/development/service-rom-b362-c432-upgrade-o-o-n-o-t3813946, you need to copy the two zip files into the dload folder in your SD card. You can also use HWOTA but that wouldn't work since fastboot isn't working for whatever reason. Or when your custom recovery is working you can use HuRUpdater. But you need to be on the newest version of Nougat B210 or B209 to update as otherwise you may brick your phone.

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

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.
