reboot to TWRP and Wipe Cache and Dalvik.....

If that doesn't help you probably need to do a Factory Reset ( Wipe Cache - Dalvik - Data )
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] roucoups:
I had already done that and it didn't work.

But now I don't know why, maybe because I had inserted a Sim card, I could have signed in. But the simcard doesn't work neither in slot1 nor slot 2. Tried with another simcard from another network, same problem.

I can't believe it, what's wrong again?????

EDIT: I'm returning to stock (with bootloader unlocked).

EDIT: simcard ok in stock. I try and root.

My case is different. I only have twrp from following tenfer's guide and additionally I accidentally wiped the system image and now I don't have root or any OS installed, but TWRP is present. Can I flash both of these files and have root? or Do I have to have bootloader unlocked and flash supersu?

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] :
So following your instructions to flash the 2 B29 files will reset your phone back to stock, correct? (since you are wiping cache, dalvik, and data) [MENTION=3044858]DrakenFX[/MENTION] ?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] DrakenFX:
I see you skip the part when I say " If you are UNLOCK BOOTLOADER proceed with step 7 "

If you want root and keep lock bootloader you need to ask tenfar for a Mod b29 boot. Otherwise you have to unlock and proceed with the rest.

Yeah, sorry about that but is the only way for now, your internal storage and sdcard will be not be touch.

Yeah you can, just boot to bootloater and use fastboot command to unlock, no worries about flashing the unlock file, this is assuming you flash my b29 files. and have OEM Unlocking enable under Developer Options

Did you try with DrakenFx Bootloader TWRP file?

Thanks for the option.

Somehow my phone is not recognizing Fastboot commands in B27 and B29 might be a driver issue. i will try at Home with latest drivers.

is anyway we can re-lock the Bootloader.. i gone through the another thread but nothing concludes it can be locked again?

Edit: Updated the driver and unlocked the BL

I want to know this as well.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] rczrider:
It took me way longer than it should have to get updated to B29. I'll document my issues and what I eventually diddid, though, just in case it helps someone.

I was on B27 with root (using tenfar's boot image and phh's SuperUser) with a locked bootloader and modified system (AdAway). I could not for the life of me get updated to B29 using the OTA itself, even if I restored stock boot and recovery, and wiped system (either by doing a factory data reset or restoring an unmodified image in TWRP). Usually what happened is that the ZTE logo would show up on boot and it would stay there, presumably forever (I waited over 30 minutes, just in case).

I decided to unlock the bootloader (http://xdaforums.com/axon-7/how-to/guide-how-to-unlock-bootloader-stay-t3461165), but I couldn't get fastboot to see the device. I eventually figured it out the updated drivers do not work, so you have to use older ones, same issue/solution described here: http://xdaforums.com/axon-7/help/fastboot-recognizing-phone-bootloader-t3492201. Even then, once I finally got fastboot to see the device, the unlock failed (I don't remember the exact error code, just the word "FAILED"). I went back into TWRP and wiped data, internal, dalvik, and cache (again), flashed the unlock zip, and then fastboot worked.

Which brings me to another point: unable to wipe partitions in TWRP. I don't know what causes it, but several times I ran into the issue where TWRP would throw errors when wiping. I can't remember the exact message, but it was something like "Unable to mount storage" in red. I finally figured out that I could get wiping to work if I did the partitions individually (I had originally checked all the necessary boxes at once and told it to wipe, which never caused issues before). And it would only work if I wiped DATA first. Whatever.

Once I got past those things, I followed the instructions in the OP and everything was fine, except that the SuperSU app itself didn't appear to be installed (and the root checker I used said I wasn't rooted). I rebooted into TWRP and flashed the zip again (note that I made sure my system was read-only both times so that it would install in systemless mode) and during the installation it said the boot image was already patched (so it worked the first time, I guess). Upon reboot, SuperSU was there.

I was also able to restore the TWRP data backup I made while on B27 without any trouble.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] `SBR`:
I will add few findings from my side when i try installing the Unlocked, B29 -> from B27 Locked BL.

It may be due to encryption issue with Internal storage, when you format the data all the option would work. if you haven't formatted data it can't wipe the Dalvik/ART Cache will not proceed to the next step. uncheck the Dalvik option will perform other steps checked in advanced wipe

i have tried the same with System Modifications Allowed, but if you're flashing the Super SU along with ROM first time it's not patching the Boot Image (you can see it will show only half the Installation step in TWRP), you have to completely boot once and reboot to TWRP and flash the Super SU then it's patching the Boot Image and able to get RooT
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] dennis96411:
I'm baffled. I assumed the boot stack was the cause of it since it's broken even after restoring my B20 backup. How would I even go about diagnosing this?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] DrakenFX:
When you are Lock and you go Unlock bootloader, if you have TWRP while doing the unlocking you'll need CANCEL and do a FORMAT DATA which is under WIPE, the Wipe Data won't work, but Format Data will.

happen once to me and i have no idea why didn't show up the first time and after a reboot/reflash SuperSU was there.

yeah , you can use B27 or even B20, even G or Chinese boot+system without a problem. :D

Why not Re-Download B29 Bootstack and Check MD5 and redo the process?

myself and other have updated using my files and there is no issue, i even when back from scratch and flash both again and there is no issue with audio calls
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] dennis96411:
I'm also get a screen at boot telling me my bootloader is unlocked and my phone is "unsafe". Is that normal?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] xtermmin:
Yes, it's normal. If you press a volume button during that screen, it'll present you with boot-up options: Power Off, Restart, Recovery, Fastboot, "previous page" (continue booting)

that's strange to me. my b20 twrp backup was no good after doing b29 process. it actually messed up my partitions i belive...i had to re-flash b29 bootstack to be able to boot b29 back again without it messing up.

i came directly from b20_boot to b29 and have not had a properly working phone for most of the day (no call audio in b29, no modems in restore of b20). going to try a do-over of the b29 process, but think i have to go back to b20

the only audio that was broken for me in b29 was in-call audio. other things seemed to work. i restored to b20 but the phone was totally unstable (would reboot every few minutes, wifi and cellular weren't working) so i didn't bother checking audio. i gave up on the phone and left it overnight. i woke up to see that wifi is now working on it, but cellular is still messed up (no IMEI info, doesn't see sim card) and now that i check, ATMOS is a big system-wide MUTE button as reported before.

there are A LOT of strange things happening with my phone and i've had to revert to using my old Z2 (which is also kind of garbage because of Sony blocking dev on it, and the ROMs out being unstable and not great).

For those with audio issues (Dolby, calls, etc.) after updating to B29 from B20, try flashing the B27 boot stack followed by the B29 boot stack. You don't have to wipe anything, you just need a few files from the B27 boot stack. It's worth a try!

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] rayman2k1:
AMAZING!! This worked for me. After four days of incredible frustration, this is what got me back up with B29:

1- fastboot flash recovery <recovery.img extracted from official ZTE update.zip>

2- fastboot flash boot <boot.img extracted from official ZTE update.zip>

3- fastboot flash recovery <twrp 3.0.2-2 recovery.img>

boot into TWRP, then:

4- flash B27 bootstack zip

5- flash B29 bootstack zip

6- flash B29 system zip

At this point, I booted into the system, but things were still messed (no radios)

So, I booted back into TWRP and 7- restored the B29 backup I had. Booted, and saw that I have Wifi. Good! Popped the SIM in and got Cellular too (good good, but I had all this before too). The real test was when I dialed into my voicemail and actually heard sound!! YES! In-call audio is working again!!!

I am not sure if steps 1-3 need to be with the exact .img files I have specified here, but this is what worked for me. The key steps seem to be, as pointed out by [MENTION=4376211]dennis96411[/MENTION], stacking the B27 and B29 bootstacks on top of each other. I think that B27 sets up the partitions that need to exist, and B29 modifies them. I am not sure why the B29 system zip didn't work, but the TWRP restore did, but I am guessing that it's because I had messed up my EFS partitions too badly and only a TWRP restore could re-create (or re-populate them) properly.

Thanks to everyone who helped me through this anxiety-inducing ordeal!!
