Thanks for all help guys. I m back in business. Installed LineageOS 14.1 and Gapps. New problems :D:D

Android asks "TO START ANDROID, ENTER YOUR PASSWORD". It does not matter which password I enter but I always get the following notification:

"descryption unsuccessful. The password your entered is correct, but unfortunately your data is corrupt. To resume using your phone, you need to perform a factory reset, you'll have an opportunity to restore any data that was backed up to your google account"

There is a button RESET PHONE which I can press then. Wheb doing that my phone restarts, TWRP does something (cannot see what because it is very short) and after that LineageOS boots again with the same thing which is asking for a password and the same notification etc.

How can I solve this?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] dprimic:
Boot to TWRP and do factory reset.

I have not experienced muted sound issue and when calling using Hangouts or any other similar application, there is no problem with echo. So i think that the problem source may be the same but not necessarily directly related. I have tried to flash modem and bootloader again after updating LOS but it does not have any positive effect or any effect at all that i am able to recognize.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] sanderh:
thanks it worked.

So running LineageOS 14.1 now and experiencing an initial problem:

when calling outbound my calls are muted. I can solve it by putting the call on speaker and switch back. How can I solve this problem?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bkores:
This is a known bug and cannot be solved by the user. We will have to wait until [MENTION=4911249]Unjustified Dev[/MENTION] or another Lineage developer can fix it

Ok, skipping to another ROM then. thxz
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] pierre6768:
Won't be better with other custom ROMs mate.

Some users have this bug, some haven't, but if you have this bug then you're gonne have it on all ROMs (excepet stock based ROMs)

Just an advice, you should read a bit more across all the threads here before trying someting without taking informations before ...
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] magnuselias:
Same here i have some noisy sound perhaps its what you call echo.. looks like its a routing error, after switching to speaker and back it'll gets rerouted i think.. ill look for a workaround this night ..

why unofficial supported phones like xiaomi redmi get los15 but the official supported axon7 needs to wait.

our axon7 devs have no time? not the skills? no motivation?

how many devs working on los for axon7? 1? 2? 3?

maybe they need donation for motivation [emoji6]

one really annoying behavior that has been bothering me for a while now. not sure if it is related to LOS or something else. in my country we have sim-card based mobile-id for digital authentication and messages for it are coming very slow and sometimes not coming at all. i have also samsung s7 with stock software and that one has no problem. i have had many phones with stock and custom-roms and usually when rom has working sim toolkit there has been no problem using it. any ideas what may be wrong here?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] celoxocis:
seems to me that updates to the device tree have come to a stop completely?

[MENTION=4126377]tdm[/MENTION]

I recently upgraded my entire home WiFi home network to WiFi mesh and noticed that the LOS axon7 build would not seamlessly switch between mesh nodes. especially noticeable while streaming content or playing a game. while walking around the house. (hence switching nodes)

the connection would drop completely and reconnect to the stronger node. which is NOT seamless.

I noticed my other two dev phones do not have that issue. so I looked into the WCNSS config. which was the cause. I was able to fix it. and it works flawless now.

i know you guys don't merge commits I push via gerrit. so I won't bother.

if you are interested in the fix let me know.

added:

it also fixes an issue where apps that require WiFi data background transfer while the phone is asleep to update app information.

such as the YATSE remote control app for KODI.

it no longer times out and show the media center as "offline".
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] tdm:
Both me and u-dev are busy with many things. If you have a patch that fixes something, I'll certainly look at it.

Rebbots

I'm also troubled by a few daily reboots (soft and quick). Occasionally a screen that dies and when pressing the power button the screen will not turn on again. The only way forward is keeping the power button pressed until the phone reboots (cold). Unfortunately I do not know exactly when this started, but probably 1-2 months ago.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] magnuselias:
I compiled the unchanged sourcecode from git, used axon7tool to modify boot and flash the rom, i have no reboots no recognizeable bugs at all! Yesterday i flashed llama-kernel which is running great as well... so should be no diffrence to the official build, when they have the recent androidbuildroot.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Super.Alberto:
Works fine for me.

Make sure your SIM card is machine cut.

I had a hand-cut SIM reduced from Micro to Nano and it intermittently went offline.

Replaced with a correctly cut SIM and all good.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] sourbear:
Seems we haven't had any Axon 7 specific updates in at least the last five LOS updates. I don't think we've had any device specific updates since early August. Meanwhile in that same time, my Axon 7 has gone from no problems, to constantly freezing and rebooting.

Also I noticed in today's LOS update, there is four 'DO NOT MERGE' changes that have been obviously merged or they wouldn't be in the update.

*patiently waiting on my Pixel XL 2 to arrive*

Edit: Also occasionally the screen dies and when pressing the power button, the screen will not turn on again. The only way to get functioning again is to keep holding the power button pressed until the phone reboots.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] ssirK:

Any chance you'll upload your fixes? I have this issue at my work, which is quite annoying.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] celoxocis:
i will in time. I'm currently working one of my other dev phones. which is way over due.

but the WiFi fix works flawless. I can literally walk across from one end of my home to the other end. cross three WiFi mesh nodes and keep playing MCOC. (perfect game for the test as it complains on every little connection drop and forces you to reconnect to their server).

I want to run an iperf test (TCP/UDP) before cleaning up my config and pushing it to gerrit but didn't have time to test. I'm also waiting for a new switch to arrive which will upgrade my connection to my homelab server to 2Gbit to max out the WiFi nodes which max out at1300mbit.

I know the axon can't push past 866Mbit but i like to beat two birds with one stone.

I seem to be getting A LOT of wakelocks and battery drain from having "Keep Wi-Fi on during sleep" set to Always. Turning it off significantly improves my battery life and stops the wakelocks.

I've attached a screenshot of BBS showing "supplicantwifiscannerimplpno" as the culprit that disappears when I disable that setting.

Due you think that your fix is related or may solve it? Do you have any advice? Thanks
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] celoxocis:

Do you have any idea how we could fix the mute call bug?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] aLexzkter:
I've noticed on ResurrectionRemix that sometimes when I play a voice clip on Whatsapp and put the phone close to my ear, the screen turns off but the audio playback stops. Rebooting the phone fixes it and the audio is played through the earpiece like in a phone call when you put the phone near to your ear.

Is this the mute call bug?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Arbelzapf:
The same happens when you use Signal. I always thought this was a bug in that specific app, but maybe there's more to it

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Tebor:
The bug I'm talking about is when you make or receive a call while the ringtone is muted or the do not disturb is turned on, you cannot hear to other person through the earpiece and toggling the speakerphone fixes it

Is anyone else having trouble connecting the phone to your PC on a USB 3 port? If I connect it via a USB 2 port data transfer works fine. Switching to a USB 3 port with the same cable only lets me charge, not transfer data -- no matter what I do in the USB config settings. Anyone heard of this problem before?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Masterjuggler:
That sounds like an issue with the computer. Assuming you're using windows, there are specific USB 3 drivers that you need, which I don't think windows 7 had by default, though 10 should. If you're using Linux based OS, you should upgrade your kernel because it sounds like you're using an old one. If you're using a Mac, you should either choose all apple crap to keep it consistent or switch to a computer that's worth the money lol.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jbeaulieu:
Not a PC issue as far as I can tell. The issue is persistent between both my desktop and laptop (both running windows 10 with appropriate drivers). I can connect my other (work) phone to either PC via a USB 3 port without issue. It's just this phone that has problems, and only on USB 3.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Masterjuggler:
Ah, I can see how you arrives at the conclusion that it's a LOS issue. I don't know enough to be able to help with that. I hope you're able to find someone that can help.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] celoxocis:
Out of my skill scope. I'm guessing it has something to do with the audio implementation.

The only one that comes to mind of who would have an idea would be intervigil. His audio implementation for htc's hima proofs his skill set.

If all the above happens on the official builds. Why not report a bug via jira?

https://wiki.lineageos.org/bugreport-howto.html#what-not-to-report

I don't see the mute call bug reported at all:

https://jira.lineageos.org/browse/BUGBASH-718?jql=text ~ "axon"

The LOS dev's usually help each other out on squashing bugs. If it's reported and enough logs are grabbed. . I'm sure of it. It will get fixed.

On another note.

I made some progress on my wifi roaming tests.

I got the axon7 to show it's actually a 2x2 and MU-MIMO device.

you can see it's not a bug. the antenna's even report different speeds depending on reception quality.

But for uknown reason i can't get it push beyond 211 Mbits/sec with my iperf3 tests. Although roaming between the nodes works seamless.

[ 5] 17.00-18.00 sec 25.2 MBytes 211 Mbits/sec

It could be my wifi mesh setup or something else. to many factors to tell.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jbeaulieu:
So after some additional digging I admit I'm even more confused. If I enter fastboot mode, I can attach the phone to a USB 3 port with the original cable and have it be recognized by Windows -- I can even issue fastboot commands over the connection. But as soon as I boot back to system, I'm restricted to only using USB 2 ports. So it appears to not be a hardware problem, afaik.

Anyone have the slightest idea of what could be going on? I'm happy to take/post logs, but honestly I don't even know what I could be logging at this point.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] celoxocis:
here is some info for those curious of you about the 5Ghz capabilities/limitations of the Axon7.

while working on the wifi settings and testing them thoroughly on my home lab env.

i came across the discovery that even though the 5Ghz are advertised as 866Mbps you will never reach those speeds.

because ZTE has been cheap. the axon7 has two wifi antennas.

only one of the antennas is a dual-band antenna (2.4Ghz/5Ghz).

the second one is a 2.4Ghz antenna.

so the axon7 is 2.4Ghz 2x2 MU-MIMO capable.

but for 5Ghz its only 1x1 no MIMO.

i came to the conclusion while working on the chainmasks and antenna diversity.

i tried to push it beyond 265mbps (WPA2 encryption) and discovered if i switched to the second antenna

and run the 5GHz from that antenna (which is an 2.4GHz antenna) the bandwidth did not just suffer... it was a joke.

i suspected a wrong antenna diversity but that was not the case. that second antenna is only capable of 2.4Ghz.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] sirizak:
That is disappointing but not altogether unexpected, the price of this device was incredible compared to other flagships, there had to be corners cut somewhere.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] celoxocis:
I agree on it not being unexpected and to cut corners.

But they should have listed the proper information/specifications then, which they didn't.

---------- Post added at 11:41 ---------- Previous post was at 11:24 ----------

I'm releasing my current config here guys, for a "public test".

i still want to add proper comments and re-arrange the order (cleanup work) before pushing it to gerrit. but feel free to test it.

all you have to do is to mount "/system/etc/wifi" as RW and overwrite "WCNSS_qcom_cfg.ini" with the one provided and reboot your axon7.

changes:

i have added settings that (according to google's documentation) should conserve power.

enabled offload features, so the processing is taken off the cpu and is done by the chips offload feature.

verified those features are working and don't decrease performance. by running iperf3 TCP/UDP tests with every settings change.

fixed and improved seamless roaming for WiFi networks with multiple nodes (includes mesh setups and repeaters).

I've read that LineageOS already implemented a fix for the Krack exploit...can anyone confirm that the latest build has this fix included? Thinking of switching from stock for this reason.

*Edit*

Found the answer to my own question. The 10/16 build does not have the patches to wpa, but it should in the next...

https://download.lineageos.org/axon7/changes/
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] celoxocis:
there could be two reasons.

1: you might have a coverage gap between the nodes.

2: your nodes don't handle dual band switching properly between 2.4Ghz and 5Ghz.

2.4ghz kicks in for better range coverage. or if u are surrounded by thick walls and 5ghz can't get through. so your nodes should make a handoff from 5ghz to 2.4ghz seamless. most vendor's don't implement that handoff properly and you get "disconnects"
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Arbelzapf:
This might be it, thanks a lot for the hint. My (very old) router can only do either 2,4ghz or 5ghz but the repeater is more recent and does dual band. I totally forgot it does that.

So I disabled the 5ghz band and will test for a while.

... And I should finally upgrade my router before it gets KRACKed. Thanks again!

[MENTION=2494638]celoxocis[/MENTION], thanks for the clarification. I myself was puzzled by this limitation and seeked further information on it as I do not have the needed tech skills to investigate myself. So created two threads:

https://xdaforums.com/newreply.php?do=newreply&p=74164065

https://community.zteusa.com/discussion/51357/a2017u-dual-stream-antenna-ac-wifi-866mbps-connection

Seems that the A2017G has 2x2 on 5ghz ? You can check the screenshot in one of the above threads, where it shows 866 mbps connection on 5ghz wifi.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] celoxocis:
negotiated link speed is done by the firmware and the wcnss settings. my axon7 also connects with 866mbps link speed but it is incapable to do so because the second antenna is not 5ghz capable. you will only ever get 433mbps throughput.

it has nothing to do with the soc or lower quality soc. it's simply ZTE cut corners on the antenna's and went with a chain of 2x2 for 2.4ghz but 1x1 for 5ghz for the antenna setup.

I've worked in the WiFi field for years. and had to debug such issues on enterprise level. seen a lot of f**p ups by vendor companies, firmware and hardware wise. a lot of today's real time data capturing for the automotive industry is all done via high speed WiFi links. you can image the insane amount of data pushed through those links with over 200 sensors on the vehicles.

---------- Post added at 12:33 ---------- Previous post was at 11:39 ----------

@dr3am_r

if you are still curious and want your A2017U to forcefully connect with 866mbps link speed

simply take my wcnss config and edit the following values:

gChainMask_5g=1 => gChainMask_5g=3 (forces 5Ghz to use 2x2, both antennas)

gVdevTypeNss_5g=21845 => gVdevTypeNss_5g=43690 (forces it to 866mbps)

but you don't want to run with these values as a daily driver.

you will suffer 2.4Ghz performance and 5Ghz performance.

as you are forcing 5ghz frequencys through a 2.4Ghz antenna

you will cause interference's on 5ghz and the 2.4ghz.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] dr3am_r:
:) Thanks but there is no point in forcing 866 connection speed if the real speed will still be 433 or worse :). What I wanted to know if the hw is there but there is a sw limitation for connection to 433 mbps. Eh anyway ... where do we need 866 mbps connection on the phone anyway ? Speedtest ? Local network transfers ? Perhaps but ... far to rare ...
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] celoxocis:
no SW limitation but HW. see my explanation about the second antenna.

866mbps can come in handy for example when i copy big rom files from my NAS (which also acts as the build machine) straight over the wifi network to one of my devices.

other than that not really required for home usage on a cell phone.
