I'll start off by saying, I'm on a factory unlocked bootloader (back with ZTE offered unlocking for a short period)

I had absolutely NO problems updating my rooted B15 (2017U) to 7.1.1. I didn't even lose any of my apps or data (not sure how that happened?).. I did the following:

I booted into TWRP, formated my data, then followed the steps in this thread, skipping the B29 rollback steps: https://xdaforums.com/sho...82&postcount=2

1) I booted into TWRP and did a format

2) Wiped everything except Micro SD and USB OTG (this step alone should have nuked all my data?)

3) went to Mount and ticked "read only"

4) Flashed A2017UV1.1.0B15_bootstack_by_DrakenFX.zip

5) Flashed A2017UV1.1.0B15_systemstock_by_DrakenFX.zip

6) Wiped Cashe/Dalvik

7) Rebooted (unplugged my usb cable first, not sure if I needed to or not but it hung the first time when it was plugged in)

I seen a screen that said "Decrypting Data", which scared me....But took about 2 minutes, then booted up and EVERYTHING was stock and right where I left it! All my apps and data was still there, along with the stock apps I had previously removed via TiBu.

I checked for the 7.1.1 update.... It found the update, and updated just fine!

After the update, I installed TWRP and rooted my phone again:

I booted into the bootloader, flashed TWRP 3.1 (using the PC fastboot command)

Rebooted into TWRP and flashed su1.79 (and my font) -wiped cashe/Dalvik (again).

Before rebooting, I also did the "reboot disemmcwp" using the TWRP terminal - Not sure if I needed to, but I did?

Rebooted, and I now have rooted, stock 7.1.1 and didn't have to spend 2 hours setting everything back up again!

Not sure you will have the same results as I did... I was frankly really surprised I didn't have to start over (like I planned on doing) and spend 2 hours installing and setting up all my apps.

What are you defining as bootloader firmware?

For those on non a2017u devices, keep in mind, while the android OS might be a2017u B15, the rest of your firmware is likely not. This includes the modem, wifi/bt firmware, bootloader (aboot.img), and a number of other low level system partitions. This update package checks that everything matches before applying the update. If a single component does not, it will fail. This is a good thing, because if it does flash those, there's a chance of soft or hard brick resulting.
[ZTE Axon 7 Guides, News, & Discussion] peramikic:
You can check the TWRP log, but my guess is you did not wipe /data. So the system was back to stock with two zips, which allowed it to update to 7.1.1. The /data stuff was all compatible even with new /system apps so your were good there. I do this but differently, i restore /data from TWRP if i have to do factory reset after OTA for some reason. I try to keep /data whenever i can

My phone (on 7.0) is unlocked and rooted with TWRP installed. When I connected to PC, I got update to 7.1.1 message (this only shows up when connected, Not on WiFi). The 7.1.1 download completes and starts to install. It rebooted into TWRP, so what do I do now? I rebooted System, phone booted but the downloaded 7.1.1 gone and I am back to my system stock. Please let me know what I should do.

i have extracted the Boot and ssysem image and made TWRP flashable of B19 7.1.1 (using Drakenfx zip's). but don't know how to extract the bootstack..

take backup of current rom, try flashing in twrp, and Supersu and see it's bootable (i haven't tested yet) or wait for [MENTION=3044858]DrakenFX[/MENTION] to post the files.

[ZTE Axon 7 Guides, News, & Discussion] twoi:
I flashed from LOS to stock B15 and OTA updated to B19. Then, fastboot flashed TWRP.

Worked great, but every time the OS boots it would overwrite TWRP with stock recovery. I don't think B15 did that.. I restored my LOS backup for now.
[ZTE Axon 7 Guides, News, & Discussion] `SBR`:
you need to flash the SuperSu or no-verity file after rom so that it will not overwrite the recovery. All stock rom will do it, even B15....
[ZTE Axon 7 Guides, News, & Discussion] twoi:
Duh.. I'm so used to rooting at the same time I forgot, I just didn't bother with SuperSu this time. Thanks.
[ZTE Axon 7 Guides, News, & Discussion] JeromeLeung:
Doesn't seem to want to start the download. Is it because it's a bigger file it takes longer to start up?

OTA capable and unlocks fastboot operations."). I didn't touch anything, just changed modem driver. I don't know is anyone who followed that tutorial and installed B15 on that way made successful update on 7.1.1.?

How is it's camera performance now does it has improved after 7.1.1 update... Tell me I'm very eager to know:confused::cyclops:
[ZTE Axon 7 Guides, News, & Discussion] foopy:
It worked for me. In fact I did a clean install of B15 using this method before I updated to B19 7.1.1. After installing B15 using the EDL method and after it booted up for the first time I went into system updates and checked for the update. It found the update, downloaded it, and then rebooted and installed it just fine.
[ZTE Axon 7 Guides, News, & Discussion] khangozzy:
After EDLed the full B15, did you have to unlock the bootloader again?
[ZTE Axon 7 Guides, News, & Discussion] Velrix:
Once you unlock the bootloader its unlocked until re-locked. OTA's will not re-lock it.
[ZTE Axon 7 Guides, News, & Discussion] Wuchko:
So, you have unlocked bootloader then? Or you lock bootloader after installation? I'm asking this because I have unlocked bootloader and don't know if I need to lock it . And just I said, only difference is that I put chinese modem in ROM.

EDIT: error I'm getting in recovery is:

error in [MENTION=688605]cache[/MENTION]/recovery/block.map

(Status 8)

There is also some error with "modem something " so I guess I can flash only untouched ROM. But can I then flash chinese modem on 7.1.1. somehow?
[ZTE Axon 7 Guides, News, & Discussion] sdbirder:
I'm having Bluetooth sound issues with the new update, minor skipping and distortion. Pretty easily fixed by powering down my BT speaker and reconnecting. I've never had issues before. Other than that A2017U 7.1.1 OTA appears to be working flawlessly.

It also got everything correct with Verizon. No need to manually put in the APN's like before.
[ZTE Axon 7 Guides, News, & Discussion] TheBoozer:
I followed the same procedure and now I have 7.1.1. The bootloader remained unlocked but I lost Root, so I will try to get it back by installing SuperSU2.79. But now for some reason, when I connect to PC, no files are listed in the SD card, and only a few files are listed in the phones memory. However when I check the files in File Manager, the SD card files and internal memory files are all there. Any ideas?

---------- Post added at 10:08 AM ---------- Previous post was at 10:03 AM ----------

One more thing, I lost TWRP. Tried booting by holding power + Volume up, did not get TWRP but the normal system recovery.
[ZTE Axon 7 Guides, News, & Discussion] `SBR`:
USe EDL or Fastboot method to install TWRP, boot it into recovery directly and flash the SuperSU2.79 (not the SR3) immediately before reboot.

To See the SDCard in the stock recovery you have the OEM Unlocking to be enabled in Developer Options i think.
[ZTE Axon 7 Guides, News, & Discussion] d.cortez:
i've been struggling to get Root as well. i successfully installed the 7.1.1 update, installed TWRP, flashed SuperSu 2.79 (UPDATE-SuperSU-v2.79-2016-1211114519.zip) and after opening SuperSU app (post reboot to system), i get a message saying there is no SU binary installed. i'm stumped...
[ZTE Axon 7 Guides, News, & Discussion] `SBR`:
Flash it again, sometimes supersu can't modify the boot. Img correctly in the first time... Try Reboot disemmcwp in twrp terminal as well after flashing supersu

You may have a modified system, or something like Magisk using system-less system mods.

He's not alone with USB not working on PCs. Stock recovery, installed the driver (and it was installed prior and worked fine). No matter what MTP mode never works now. Camera mode does. Tried on multiple PCs which worked before.
[ZTE Axon 7 Guides, News, & Discussion] Cyrus D.:
Is this OTA available as a TWRP, fastboot, or EDL flashable package yet? I can't just update through the OTA since my bootloader is unlocked. Flashing to the stock recovery in an attempt to use to use the OTA just results it in saying there's a mismatch.

Edit: Did I see something about people not being able to have their phone/files detected when hooking up to their PC? Microsoft recently forced out a ****ty broken USB automatic driver update, that could be the issue.

- Reinstall your Qualcomm USB drivers, the fastboot driver

- Hook up your phone, go to the device manager

- Right click Axon 7 under portable devices and click "update driver software"

- Click "browse my computer for driver software"

- Click "let me pick from a list of device drivers on my computer"

- Select "MTP USB Device" and click next

That should get things working again. My phone still doesn't show when I type in the adb command to show a list of fastboot devices, but flashing to it does work.
[ZTE Axon 7 Guides, News, & Discussion] Narada2XK:
If you don't have a microsd card and you have TWRP, can't you flash the full update via OTG?

I tried putting the OTA update.zip on a 2GB microsd card and it won't work on TWRP "error 8" nor the B15 recovery.

Also, what apps could prevent the OTA from being available under updates? Busybox? SuperSU? Secure Settings? Tasker?
[ZTE Axon 7 Guides, News, & Discussion] `SBR`:
First time ig didn't work for me this is the steps i followed

1. Enabled debugging

2. It's pop up to accept connection from computer.

5. Now selected MTP, it does connects and showed internal and external...

My installation,

Updated through Ota, format data /factory reset in Stock recovery. Flashed twrp wiped internal storage /cache/dalvik
[ZTE Axon 7 Guides, News, & Discussion] foopy:
No. It remained unlocked.

---------- Post added at 10:07 AM ---------- Previous post was at 10:02 AM ----------

Yes. I unlocked the bootloader several months ago using the downgrade method. If you already have an unlocked bootloader I suggest NOT re-locking it. That Chinese modem may affect your ability to install proper updates. You may have to EDL to B15 in order to update to B19 7.1.1 OTA

---------- Post added at 10:10 AM ---------- Previous post was at 10:07 AM ----------

I re-flashed the latest TWRP using fastboot. As far as seeing files try using the pull down menu and tapping"Media device MTP" again and see if that works.
[ZTE Axon 7 Guides, News, & Discussion] Wuchko:
It's not problem for me to flash B15 again through EDL and with original modem. But then I don't know how, where and when replace the original modem with chinese (because I will not have network service with US modem)? I don't know if I can replace modem in standalone B19 update package and flash.. This issue drives me crazy...
[ZTE Axon 7 Guides, News, & Discussion] lafester:
Why not just flash draken’s b19 in TWRP?
[ZTE Axon 7 Guides, News, & Discussion] Wuchko:
I have stock recovery, so I need to flash TWRP and then draken's B19? And that B19 will not touch modem? In that case, everything is clear :)

EDIT: as I can see in this thread, I must flash bootstack and stocksystem. But which bootstack I must flash if I still want B19? I guess B19 also. But my phone is A2017, not A2017U? Just when I think I've figured it out, I realized that I was even more tangled...
[ZTE Axon 7 Guides, News, & Discussion] Your Pal Dave:

I am thinking of restoring to Factory from Settings and starting all over again. I am assuming that this action will Lock the phone, Un-Root it and remove TWRP, am I correct in my assumption and do you advise it as a last resort?

If you're A2017 I wouldn't flash any of the stuff for the U variant.
[ZTE Axon 7 Guides, News, & Discussion] lafester:
You can flash system from any variant you want. Do not flash bootstack though.
[ZTE Axon 7 Guides, News, & Discussion] Wuchko:
So I can flash only system and it's not necessary to flash bootstack at all (in my case)? Will that work? :confused:
[ZTE Axon 7 Guides, News, & Discussion] lafester:
I have flashed quite a few different system files from Chinese and G variants using U stack. Will every combination work? Probably not. Make a backup and hope for the best.

[ZTE Axon 7 Guides, News, & Discussion] d.cortez:
if you're trying to achieve root, your issue could be related to the data partition NOT being formatted as EXT4. i had problems with SuperSu and Magisk; once i formatted the data partition as EXT4 i was able to achieve root. i did not go back to try Magisk. :)
[ZTE Axon 7 Guides, News, & Discussion] TheBoozer:
Update: I rest to Factory and set the device as new and then restored my data from a backup. Now, the PC recognizes the CD card and reads the files inside it. My phone is still unlocked and has TWRP but lost the root so I rooted with SuperSU 2.79. This was the only way to resolve the problem.

To those of you who have received the OTA notification on your phone whereabouts are you located?

I ask because I'm in the US and on T-Mobile and haven't received the update notification yet.

I can tell from the OP's screenshot that they're likely somewhere in the Middle East based on the carrier, but I'm curious how many US users got the OTA notification to their phone.

Being one of the listed features of this update is T-Mobile specific, I would've thought I'd see it already.
