A little help please... - ZTE Axon 7 Questions & Answers

I have the US version of the ZTE Axon 7 running the B29 build.
I recently unlocked the bootloader successfully, When I flashed the TWRP recovery via fastboot soon after, it worked perfectly. Phone booted properly and worked normally. When I tried to install the TWRP app in the OS, I was told to download the latest TWRP version from the website and flash it (even though I had the latest version already flashed from fastboot). I did that. Now I have no recovery menu at all. I have access to the bootloader menu, and I can boot into the phone. When I try to boot into recovery, all I get is a black screen. I tried to reflash the TWRP recovery img from fastboot like I did originally with no success this time. Fastboot recognizes the phone when I type devices, but when I type the fastboot command to flash recovery twrp.img, it says it can't load the file. I then downloaded the ZTE stock recovery img and tried to flash that with the same result. I assume the recovery partition is locked somehow now? What can I do to recover the recovery? Am I stupidly forgetting something trivial.

hello, this happened to me once on a Nexus 7, I did a clear cache/wipe and restore I think, I got it to work.
Not sure if this will solve your issue but you can give it a shot...
good luck

I would never flash a recovery from an app unless there was no other option. Use tennear/tenfar tool to flash twrp.

Thanks for your suggestion. I cant wipe/flash/ recover/or even reset to factory because I have no recovery menu at all. Unless there's a way to do that outside of the recovery boot menu.
At least it's not bricked.

I think he means go to fadtboot and do fastboot clear cache or something like that, Google fastboot cache clear command

Cannot flash TWRP. Stock recovery is persistent

Hi,
In order to update my phone to oxygenOS 2.2. I flashed oxygenOS 2.1.1 full rom and installed the OTA update for 2.2. Because of this the phone switched back to stock recovery. So I tried to install TWRP recovery through fastboot. The installation was successful but after reboot, it looks like the phone is keep switching back to stock recovery. I have tried this many times but same result everytime.
Note1: I did turned on the USB debugging before this.
Note2: Bootloader is unlocked.
Any help would be great. Thanks in advance!!
When TWRP asks you to modify system partition give it permission to do so at the start of booting to recovery

The problem is that I dont see TWRP even once after flashing it. After flashing when I reboot to recovery, it directly shows me default recovery. When I said its switching back to stock recovery, because the flashing of twrp was successful, I am assuming that it is switching back to stock recovery.

I also experienced this the first time. But I just ran fastboot flash recover openrecover-twrp-2.8.7.0.img one more time and then rebooted the phone and pressed volume down until it entered TWRP.

Did that many times, but it keeps getting entering in the default recovery.
What happens when you boot twrp with fastboot instead of flashing?
Also probably shouldn't flash an ota 2 versions different than the full. If that was the full version you already had, should have flashed 2.1.2 ota then the 2.2.0 ota.
I'm having the same issue. I was able to boot into TWRP once from Fastboot, flashed SuperSU it said it was successful, then I rebooted. Root was not available, and stock recovery was back.

Can't boot into recovery no matter how many times it is installed

Hey XDA, Recently installed Paranoid Android coming from Chroma and it's not stuck in a boot loop. I can boot just fine every time besides the annoying corruption google warning, but no matter how many times I try to install TWRP it just won't let me boot into recovery. I'm using WugFresh's NRT kit. Can't seem to figure it out. Any suggestions?

My suggestion is for you to fastboot flash the TWRP recovery image instead of using a toolkit. You cant see the inner workings of a toolkit and have no idea of what it is doing. The toolkit could be using the wrong commands to install a recovery image to your 6P. Go to www.twrp.me and search for the recovery image for your specific device and download the file. Next, rename the file to recovery.img Then, on your PC, navigate to the folder where you downloaded the TWRP image. Open a command prompt in that folder by pressing and holding the SHIFT KEY + RIGHT CLICK on your mouse and select OPEN A COMMAND WINDOW HERE. Boot to the bootloader on your device and connect it to your PC. Then type this:
fastboot flash recovery recovery.img
Then type this:
fastboot reboot bootloader
fastboot reboot recovery
Here is the link to download TWRP for your Nexus 6P
This will reboot your device to TWRP
All of this is based on the assumption that you have a working ADB installation and unlocked the bootloader and have USB Debugging turned on in DEVELOPER OPTIONS.

Same thing, successful install and it won't open. Just shows the dead android when going to recovery.

You get the same results after fastboot flashing the TWRP image? I'd say your next step is to start fresh by fastboot flashing the factory images to return to a fully stock state. Then fastboot flash TWRP again.

Do not boot directly into system after flashing the custom recovery.
After flashing boot into TWRP. I remember on previous devices that I owned that if you do not boot into the custom recovery after flashing it, you revert to the factory recovery.
Just a thought

I thought about that too. What is probably happening is his custom recovery is being patched by the ROM each time he boots into recovery. Thanks for picking up on that. I forgot to include that in my last post.

That's correct. After flashing TWRP the next step is reboot into the bootloader using the volume keys and power key , then from there boot into recovery using the volume keys and power key, then the phone can be rebooted from TWRP into Android and then after that TWRP should stick.
If the boot image is not patched, the ROM will overwrite TWRP once you reboot. flashing latest SU from TWRP will prevent this.
Thanks for all the replies guys! All the advice combined got it to work. I did some more research and found that Paranoid doesn't actually come preprooted like all the other roms I've been used to. So using the tool kit I just had it root it with the latest SuperSu and also flash a custom recovery. It has booted into TWRP no problems now a few times. Hopefully it will stay like this. Will keep everyone posted and appreciate the advice. Thanks XDA!

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

Stuck on "Fastboot Mode" screen

I stupidly tried using franco's app to flash cleanKernel on my rooted phone on 9.0.11, it failed of course and now can't boot my phone. I'm able to fastboot boot twrp.img but I'm not sure what is needed next. I've downloaded the full 9.0.11 ota file thinking something in it (or all of it) needs to be flashed from twrp. Afraid to do anything at this point for fear of losing data. Any tips are appreciated.
I've downloaded mauronofrio's rom-stock-fastboot utility but see he says it will clear data. I'm assuming all the .bat files will do this. Any way to avoid clearing internal storage?

From bootloader screen, using fastboot boot twrp.zip results in OP going to "Fastboot Mode" screen...and staying there. The zip is pushed to the phone but won't boot into TWRP. This started after I stupidly tried using franco's app to flash cleanKernel on my rooted phone. It failed of course and now can't boot my phone. My phone recently updated itself to 9.0.11, fyi.
Any ideas on how to fix this boot issue? Is it just a matter of flashing something from the full ota 9.0.11 file---some img file or something?

Wouldn't you want to be using a twrp.img not .zip?
fastboot boot twrp.img
Boot twrp from the img and then flash the zip once twrp boots?
I was able to recover...thank god. Just used mauronofrio's flash utility. Removed the "-w" flag from the flash-all.bat file and all is good.

Hi, I have just got a OnePlus 6T and I am getting this same error even though I am using the twrp.img - when I run fastboot boot 'twrp.img' it sticks on the Fastboot Mode screen.
I have the .zip on the phone's internal storage along with Magisk ready to install but I can't get there.
I did manage to get into Recovery once in the last 3 hours but under Advanced the only 2 options I have are to reboot to fastloader of reboot to recovery which just takes me round in circles!
Have tried everything I can find/think of right now and am no further down the line
Any help guidance will be greatly recieved as nothing I can find on the threads here seem to help
Thanks

When I think about it, it seems that the twrp.img I am flashing is not taking. When I go into recovery I get to choose 1 of 3 languages, I choose English and then I just get the 2 options as above - thing is, the font, layout etc. make it look like stock recovery and nothing like TWRP I have used before, no TWRP logo etc. Nothing

Ok.. can you get into TWRP? Is so reflash the stock rom.. the once it has flashed do not reboot, go back to install and flash the lastest twrp .zip do not reboot, go back to install and flash/install magisk, once it installs then reboot to system... It will take a bit... Once it reboots check your Magisk manager you may need to reinstall it, reboot to TWRP and reflash it.. reboot to system band you should be good to go...
TWRP isn't there

Thanks and apologies if a two posts appear from me, I submitted one about 20 minutes ago and it isn't showing.
The issue is more than that, even when I try to flash the TWRP image it doesn't seem to take. The phone gets stuck on the 'Fastboot Mode' OnePlus flash screen and hangs there.
I have to hold the power and vol+ keys to get the device to restart and I then receive a message saying 'bootloader unlocked, data insecure etc.' and to press the power to stop the boot process. If I leave it the phone boots into OOS10.3.3.
If I press the power button I can get to recovery mode (albeit there is a password screen there which I have never seen on other devices I've had). I put my password in and choose English. I am then given the two options; reboot to fastboot or reboot to recovery. There is no advanced option to allow me to install TWRP or Magisk zips, as a matter of fact I don't get any TWRP at all, it looks like stock recovery.
Is the phone defaulting to stock recovery and not the TWRP image? That is what, in my very non-expert opinion seems to be happening. Is that possible and if so, any ideas how to fix?
I have completely flashed the phone so it is on stock OOS (10.3.3.) so can start afresh. It is a refurbed 'like new' so could that have anything to do with it?
Thanks for reading the long post - am wondering if there are some other tools I need use to change how it boots?

Ok.. are you using the latest TWRP? If you want in the guide section you can you the msmdow like ad tools to reset you phone to stock, and retry again..
THIS. I have the exact same issue. In short, I have the T-mobile version, and was able to unlock successfully. I am using twrp-3.2.3-0, and I have the img and zip in the same folder, same way Techibee does on Youtube. I then type "fastboot boot twrp-3.2.3-0-fajita.img", I get the "OKAY... OKAY... Booting... Finished" response in console. Then, the Fastboot screen appears and never leaves. I have done this 3 times now. I kept tweaking the process, but I'm nervous to keep debugging.

Nokia 6.1 installed TWRP problems since

Hello,
I recently tried to degoogle my phone with Lineage and twrp. It's been a bit of a brick wall. Long story short i'm stuck in twrp. It boots into recovery fine from that. Everything else is DOA. When I plug it in the pc recognizes it and I can see my storage. I run adb devices and it comes up. When I reboot to bootloader I see download as I should on the phone screen and I hear it connect to the pc. Then that's it, it doesn't show up as storage or when I run adb of fastboot commands. I fairly certain TWRP F'd this all up. I have the recovery image for lineage but like I said nothing gets done.
So the question is, is it totally bricked or is there a soulotion I haven't found yet?
Thanks for the listen.

First of all flash LineageOS recovery on fastboot mode then restart to LineageOS recovery & flash LineageOS rom via adb sideload...
Everything you will do even working fastboot mode...
A/B partition system is caused whole problem so this is only the method to flash custom rom...
As I said this has been the whole problem. I boot back to bootloader where It says Download Mode. When I try to flash the recovery image this is what I get.
C:\Users\rpwor\NexusTools>fastboot flash recovery lineage-18.1-20210831-recovery-PL2.img
< waiting for any device >
And there it sits never to move again. Now do you understand what i'm dealing with?
The problem might be the recovery image you want to flash as it's for a Nokia 6.1 (PL2) not Nokia 6.1 Plus (DRG).
If your device is actually a Nokia 6.1, then you could try the `Install Recovery Ramdisk` option in TWRP, under `Advanced`.
