A2017U B03 restore to B20 or B27 - ZTE Axon 7 Questions & Answers

I was dumb. I decided to flash the euopean Axon 7 (a2017g) B03 twrp file to my phone and now I've lost TWRP (was able to get root back but cannot recover TWRP). I have tried the EDL method and Fastboot. Nothing sticks. So now I am here begging for help from fellow members. How to get my A2017U back to B20 or B27. My bootloader is officially unlocked if that makes a difference.
Thank you.

Bootloop after updating to B27

Hey folks,
i have a big problem updating my Axon 7 to B27. I've tried everything, stock system B20 then updating to B27, causes the same bootloop as restoring (system or TWRP Backup) B27 direct through TWRP.
The next thing is i can't update my Recovery to the newest TWRP version, i get only black screen if i start to the recovery after updating. Only the recovery from tenfar B20 root is working so far.
I'm unlocked and rooted, but tried to lock the bootloader with the same result as above.
@DrakenFX, @Unjustified Dev, maybe you have some ideas?
Best Regards
Even if i update with @DrakenFX B27 Bootstack and Update i only get to the SIM lock screen and the phone reboots.
Is nobody else facing this problems?

*SOLVED* Update 7.1.1 retain data

I was on b15 wanted to go to the new b19 7.1.1. I was rooted with TWRP with an unlocked bootloader. The easiest method I found was to use the Axon 7 toolkit and use miflash to flash stock b15 and had the option at the bottom to keep user data. It flashed and I booted it up all my apps and data was still there. I proceeded to take the b19 update and reboot. Everything ran fine so I reran the toolkit to flash back TWRP and rerooted....Mission accomplished.

Where can I find latest stock recovery for A2017U and flash it over the TWRP?

So my A2017U is bootloader unlocked and TWRP installed. Is there a way I could go back to the stock recovery as right now for all OTA's the phone won't properly install the update.
I've searched and noticed Draken posted one for A2017G B06-09, but not sure if I could use these.
thanks a ton!

ZTE Axon A2017 B17 Nougat 7.1.1

Hi,
I have tried for weeks now to unlock my bootloader, but to no avail. Most of the zip files posted are for B20 or B13 builds. Unfortunately my system returns an error when trying to do the update both from the SD card and from ADB.
Please help.
Thanks in advance!
where is B17 is avalble?
and you cant unlock the bootloader from stock recovery
Pushed a 94.45mb b17 update. Refused to install on my phone even after reinstalling the stock recovery.

Do I have to downgrade B19 to root?

Let me start off by saying I've been a member of this forum a long time and I'm not new to rooting. However, my last 2 phones didn't have root exploits when I bought them (G5 & Motorola z Force). I'm currently in the B19 build and all the steps I see involve downgrading from b25 to B19 to root. Can I unlock bootloader, root and install twrp while on B19?
Thanks in advance! Thanks to all the wonderful techies & gurus who figure these exploits out.
Yes, as of b25 disabled unlocking. With b19 you're okay.
AFAIK the B25 update disabled fastboot, NOT unlocking. Try axon7toolkit, it should flash a bootloader or sth
