Tried it, but...

I flashed the beta to recovery, and this is what I got:

PS C:\tuliptool> .\tuliptool-win64.exe write recovery
Sending programmer...Connecting to programmer...log: logbuf@0x08067EB8 fh@0x08064D20
log: logbuf@0x08067EB8 fh@0x08064D20

Writing recovery ...
log: start 1181696, num 45220
Write 23152640 bytes, 45220 sectors
Failed: Unknown error
Reset in 5 seconds ...
Reset in 4 seconds ...
Reset in 3 seconds ...
Reset in 2 seconds ...
Reset in 1 seconds ...
Failed: Unknown error

Afterwards, I tried to boot into recovery, and I got some sort of "Factory Test Mode" screen. I'm assuming that means I don't have a recovery or something, because the flashing failed.

Oh. Yeah. I'll fix that. The problem is that the flash tool wants an image that is an even multiple of the sector size.

In the mean time, you should be able to use dd in adb shell from the old twrp to update.

File is now padded to 1mb boundary. OP updated with new MD5. Please re-download and try again.

Is this for b12 or b14?

 

[tdm]

Should work with both b12 and b14.

Is this for b12 or b14?

Is the phone able to boot properly if I flash just the recovery without flashing the boot.bin

 

[tdm]

Yes just flash the recovery. Boot to recovery by holding the volume up button with the power button. I don't think stock updates recovery at boot, but I'm not sure.

Note you will need the custom boot image with verity disabled if you change anything in the system partition. I think SuperSU also disable verity, or at least can.

Ok. Twrp flashed successfully. Now my device just hangs at the splash screen and will not go any farther.

I can not get back into EDL or Recovery. ugh....

UPDATE: I am able to get back into TWRP if i pull off some very specific button combinations. However thats all im able to do. Android will not boot.

 

[tdm]

I'm confused how you killed android by flashing recovery.

Is it possible you flashed the modified b12 boot image on a b14 system? If that's the case just flash back the backup. I'll create a b14 boot image asap.

I didnt flash any boot image. I flashed the TWRP in this thread with the tulip tool. and did not flash any boot.bin at all. I am on B14

Also Ive noticed to get back into TWRP if this happens to anyone else. You have to hold

Power button THEN press and hold volume up.

Once the ZTE Screen loads you must tap the power button repeatedly and then for some reason TWRP will boot.

Flashed backup and now device will not boot into recovery or android at all, However I am able to still get into EDL.

 

[tdm]

Let me know if you get the device working again. I can help if you can't figure it out.

I am still confused about what could have happened...

[MrWhite0429]

Ok. I am able to get the device to boot into stock recovery and EDL mode now. However android still will not load. Device has been sitting at ZTE Splash screen for almost 10 mins.

 

[tdm]

Oh.... by any chance did you let twrp mount system read/write? Even once? That destroys the verity integrity.

[MrWhite0429]

The Device is also not responding to the wall charger any more. Im afraid if the battery dies I may have a perminantly bricked device.

 

[tdm]

Don't worry, you can't brick the device if you can get to EDL.

[MrWhite0429]

I dont believe I did. Unless I did it without knowing. When TWRP booted it asked me for a password. I selected cancel. Then I selected Read Only. And then I selected reboot to system. and Here I am. With That being said if it may have destroyed the verity then im stuck until I can flash a B14 Non-Verity boot?

 

[tdm]

Let's assume you did allow twrp to mount system RW and your verity integrity is destroyed. Just upload the original b14 boot image and I'll make a modified version with verity disabled. That should get you running again.

Note I'm getting ready to go out with my wife so it will be a few hours until I can do that.

Just flashed the backup B14 boot that I had and no luck. Device still hangs at splash.

Flash stock recovery and try to flash with the original firmware zip
