Did they remove the "assertive display" setting with the last update ? Not that it is absolutely needed (I don't even knew what it was before I saw that setting) but I found this rather strange since it seems to offer clear benefits with sunlight legibility.

For those who are having trouble with the B27 update I'll be posting a TWRP system image backup soon which I imagine should work.

EDIT: Mega says ETA ~90 Minutes the backup will include the System Image + Stock Boot + Signed TWRP Recovery. I will be making one with a stock recovery but I wanted to get this backup out as soon as possible.

EDIT 2: The TWRP backup of the system image + stock boot + signed TWRP is later in the thread: Here

Okay everyone! Here is my backup of the system image for B27 + stock boot + signed TWRP.

https://mega.nz/#!slZGVJpZ!DIukrcB07VLquCokGU_b8CPooCOR4PlgKfnnQh7CiJo (Via MEGA)

I also have a working copy that includes the stock recovery, once it's done uploading I'll post the link in this thread. Since this account is new I can't start a new post in the ROM section so please forgive me. Let me know if this works for y'all. (Do not forget to backup your current system image! Just because this works on my phone, well you all know, nuclear fission possible, I'm not responsible for WW3.)

Should allow for a seamless upgrade without wipe.

Note: It's been brought to my attention that I was unclear this is a TWRP backup not a flashable zip. You need to copy it to your phone extract it and place the extracted folder in your TWRP backup s folder then restore system image and boot.

After RESTORING wipe cache + davlik (same as it ever was)

[ZTE Axon 7 Questions & Answers] corpdecker:
Thanks lokissmile! If I understand correectly, flashing this in TWRP would reset all apps and settings and such, or is that all purely in the data section ? I assume we need to flash new root access after flashing this ?
[ZTE Axon 7 Questions & Answers] lokissmile:
It's a simple TWRP backup, so go into TWRP => Restore and restore the system image +boot; Wipe Cache + Davlik, and reboot should *in theory* work. You may need to re-root after, installing the signed TWRP is optional and are there primarily for recovery purposes and to make sure the backup has what *I need/want*) It should not wipe data, but strangeness could happen if you don't, none of this is deeply tested.

1. I am not rooted yet myself as I play Pokemon Go and can't break SafetyNET, so this needs to be tested

2. all I've done is tested that the backups work for me, I'd like to know if someone has success just flashing the system image, AFIK not flashing the boot.img could soft brick or cause other strangeness.

From my experience TWRP is not necessary if you already have it flashed, boot will likely break systemless root.

Is there a flashable version for those with an unlocked bootloader (B20_Boot)?
[ZTE Axon 7 Questions & Answers] TeutonJon78:
It's still there. I highly doubt they are going to remove that in a monthly feature update, as that is probably a fairly large undertaking to redo. I'd guess it will be more in the 7.x update. And they thought people would like it -- so they only have had like 1.5 months to even think about changing it, and this update was made 8-31, so even less time.
[ZTE Axon 7 Questions & Answers] peramikic:
If you are really up for it and risking maybe not being able to unlock for a while, update and then try to unlock via fastboot img. I do see quite a few images and patches in that zip though., including aboot sooo.. Dragons and all that ****. I wonder if they patched our exploits. Like that aboot might be now more like EU one and go to DFU instead of EDL . I can't do anything until the weekend, need to tether a lot this week. Don't think we have confirmation on either of the scenarios, one way or the other.
[ZTE Axon 7 Questions & Answers] lokissmile:
If you have TWRP, the backup I posted should work you just need to extract it copy it to your TWRP backup folder and restore system image and boot. So far i have not heard of anyone run into any issues.

Wait for the more experienced here to provide guidance, sorry for getting ahead of the game here.
[ZTE Axon 7 Questions & Answers] rczrider:
Happy to!

To be clear, which thread should I use as my guide? It's gotten a bit confusing around here :p
[ZTE Axon 7 Questions & Answers] peramikic:
Thanks for the effort really and since this is a system image, it's good for stock hash consistent restore. I do have to point out that the OTA patches quite a few of the partitions that might be needed for proper operation of the new /system. Among others what is patched is Modem, PMIC(power management), DSP(audio), DDR, BTFM(bluetooth). These probably work in conjunction to some of the system updates so restoring just system might cause some function and stability issues.

[ZTE Axon 7 Questions & Answers] TeutonJon78:
Since they mentioned overhauling the unlock procedure, I'm going to guess that something has changed. However, I was surprised to see that fastboot wasn't updated in this update. I'd have to image we'd need an update to that -- unless the update in B20_boot was a hack it to enable quickly rather than building it into aboot.

Mmmmm....the new modem is much better. The signal bars are better too, but that's fake info anyway. The update is nice and smooth.
[ZTE Axon 7 Questions & Answers] bhazard451:
So the TWRP system backup posted doesn't contain the firmware updates correct? Would one of the more knowledgeable posters here be able to make a flashable .zip of the firmware updates in the OTA?

Are you referring to updating from B20 to B27 without using the official OTA? If so, no, I don't think that will work. I *think* other files (aboot, for example) were updated in B27, so you'd need to flash anything that was modified.

I don't honestly know. My phone is still stock and I'm just pulling the same things that folks ([MENTION=540283]tenfar[/MENTION], [MENTION=3044858]DrakenFX[/MENTION], maybe [MENTION=4911249]Unjustified Dev[/MENTION] and others) used to do their magic with B20.

If you have twrp ready to go, all ou have to do is download the file, place it in the twrp folder, then you can restore the system and boot. The phone will boot up. If you need root, re flash superuser 2.65 and you'll have root back.
[ZTE Axon 7 Questions & Answers] Flapjack:
So... let me get this straight (haven't updated yet).

- Still no wifi calling?

- Still have to click notification bell? (really? REALLY?!)

- No official unlock?

- No providing of stock files?

- No OTA with root/modified boot?

- No Nougat?

Why am I bothering to upgrade?? I'm seriously second-guessing my decision to go with this phone. If I can't have wifi calling, I might as well either sell it, or wait for a CM-based ROM.

Seriously disappointed, ZTE... seriously disappointed.
[ZTE Axon 7 Questions & Answers] KyJelly69:
Thank you ZTE for including sept. security patches.

Thank you for allowing to install another lockscreen app in case I don't like your bell.

Thank you for the unlock method so shortly after releasing this amazing phone to us even though it wasn't quite an automatic process.

I'm sure you have your reasons for not supplying stock file. I will be patient.

You already warned us that there will be no updating via OTA available if I unlock my phone so I accept that as part of MY DECISION to unlock.

No one else has Nougat available right now either so I guess it makes sense that you would not either. Once again I will be PATIENT because I know you are working on it since you have already told us that this phone will be daydream compatible and nougat is needed for that.

B27

Hi. I have the Axon bought directly from BestBuy, as is (I'm not a tweaker), used in Mexico under TELCEL network, and yesterday updated to B27 via OTA. So far this are my observations.

Goodies:

1- Battery Life has improved significantly. With moderate lo light use made it to noon with 95% where as of yesterday went all the way to 80%.

2- Network and WiFi reception improved notably too. WiFi took almost a minute to lock two days ago, but TODAY was blazing fast, maybe 5 or 6 seconds. Tested on the same WiFi. On the same comparative I had 2 or 3 bars on network signal (4G) before, and right know it fluctuates between 4 and 5.

Baddies:

1- Some of my applications started crashing (weather ones mostly). Tried with some different ones on PlayStore with the same result. After 3 or 4 tries found one that it's stable. Perhaps some deal related to GPS sensor? :confused:

2- Maybe (MAYBE) it's a product of my imagination, but in order to improve the aforementioned battery life I feel that the max brightness has been toned down. I remember clearly not having an issue looking at it under the sun two days ago, but TODAY I really struggled with visibility, on automatic AND on manual at 100%.

3- On the same note referring to the toning down, I feel that they put some kind of control over the volume. Two days ago, sitting at 50% volume I could clearly hear videos and music even on a mildly crowded room, but TODAY, on the same room with the same people, I had trouble understanding the words, I used the same music and videos from YouTube.

Perhaps this last two baddies are just an issue of personal perception, but I want it to throw it out there to see if someone else has the same feeling.

--note. sorry for my bad english, if the matter arises, as it's my second language, so forgive me if some words are misaligned with the context.

UPDATE: The battery seems to be draining a tad faster today with normal use. Again, maybe perception, but I'll keep on the matter.
[ZTE Axon 7 Questions & Answers] curbguy:
Double tap

Double tap is now much more responsive on my phone. Battery drain seems a little higher, but that may be that I have played with it much more since updating this morning.

[ZTE Axon 7 Questions & Answers] justinfhersey:
I'm having issues after updating OTA to build 27. My phone is acting very strange. It's being really slow. Sometimes it want let me type anything. Then on the lockscreen it want let my unlock with my finger print or swip up to reveal the pin entry. I have to tape on a notification for it to pull up the pin entry and unlock it that way. I haven't had any issues with my phone until today. I updated it last night and it worked perfectly fine up until this point.
[ZTE Axon 7 Questions & Answers] shifuharris:
You sir are the man! Thanks for the link. I downloaded only the TWRP folder and did a restore through TWRP (after I backed up what was already there of course). Restore went fine and I am definitely on B27 now (woot!). I have issue though. It apears the fingerprint scanner is now dead. It wouldn't let me unlock with it and when I try to register new prints it doesn't seemed to see anything. Any ideas on what I need to do to re-enable the FP scanner?

Thanks!

I just had to use [MENTION=540283]tenfar[/MENTION] B27 boot.img and recovery.img and flash xposed again and root is working fine as well.

Btw [MENTION=540283]tenfar[/MENTION], there is something wrong with axon7root.exe in your B27.zip, it keeps saying the horse is dead. I had to use B27's boot.img and recovery.img with B20's axon7root.exe to make it work.

Does anyone know how to go from b20, unlocked bootloader to B27? It sounds like I need to re flash boot.img and recovery.img via tenfar's axon7root.exe tool. I backed those up prior to unlocking bootloader, so that's easy. But where can we find a stock b20 system.img? Only one I can find says it's going to take over a day to download... Any other tricks to this? Could I just factory reset via twrp?
[ZTE Axon 7 Questions & Answers] DrakenFX:
- Download stock Recovery from here B20 stock recovery

- Go to TWRP, WIPE DATA- CACHE-DALVIK .

- Make sure SYSTEM was unchecked in mount and check mount system read-only

- Flash this file ZTE_A2017U_StockB20U_by_DrakenFX.zip

- Flash stock recovery you downloaded and reboot and you can now safely just Update to B27 via System Update app.

P.S. yeah i know you'll have to start all over again meaning Reinstalling apps but you'll still have unlock bootloader and can reflash TWRP via Fastboot.
[ZTE Axon 7 Questions & Answers] JeromeLeung:
I'm trying to figure this out as well. I tried [MENTION=3044858]DrakenFX[/MENTION]'s flash back to stock zip to see if it'd let me take the update, but once it gets into recovery it says something about "unexpected contents" and a "mismatch". Kind of at a loss here.

Edit: just tried with the updated instructions. Rebooting to recovery just sends me back to TWRP for some reason. Was I supposed to enable system modifications?

Latest security update and fingerprint sensor is super fast now. Very annoyed that one can't disable some stock apps anymore.
[ZTE Axon 7 Questions & Answers] Flapjack:
I am somewhat interested in the faster fingerprint scanner, as well as the bolded clock on the lock screen (which is nearly impossible to see at a glance). Still, I had hoped for much, much more. I'm not sure if there was a post by a company rep on the ZTE forums that led me to believe it was going to be a bigger update, or if it was just the members there getting spun up.... but I was not expecting a mostly minor security update.

To be honest, if they had released an update that only got rid of the stupid dingbell, I'd have been happier than I am now. I haven't had a signal problem, or have been irritated with the fingerprint reader, which seem to be the two most significant fixes in this release.
[ZTE Axon 7 Questions & Answers] JeromeLeung:
