Thanks for specifying. Would you happen to know of any Oreo builds that support WiFi Calling? Besides stock-based ones of course. :)

sorry if the question is very noob, but if it was not a stock-based ROM, would you lose specific functionalities of this mobile's hardware? as the super audio mode, with the professional DAC that this mobile has?

Phone shutdown overnight

The ROM has been working great for months, but this morning it was in a power off state. Battery was above 90%. When I powered on, there was a notification that passed by briefly saying something like "performing boot operation". I don't see this on subsequent reboots.

I thought perhaps this was due to a ROM update, but I'm still on ViperOS version 6.7, build date Sep 24.

I checked the web site https://download.viperos.org/?codename=axon7 and this is still the current version. But I am confused, because the beginning of this thread indicates an Oct 5 security patch update:

Pc connection doesn't work..

Guys, I have a problem and it's really annoying. So every time I try to connect the phone to the the pc it doesn't get detected. I tried every connection method (MTP, thetering, only charging etc), I've also tried the same but with adb on and in this case it sometimes connects and shows the main folder but it results empty. The only properly working way is mounting via TRWP and while in recovery it works. Any ideas on how to solve this?

N. B. Drivers are okay. I've checked.

On same ROM, when I connect to PC, a notification appears from ANDROID SYSTEM > TAP FOR MORE OPTIONS and when I do, it lets me choose which mode, such as FILE TRANSFER or MTP or CHARGE ONLY, then I can copy files back and forth between both devices. Hope this helps!

hey guys, long time since i installed my last custom rom... so I'm a big time noob.

i got viperos working now, installed an full edl image with axon 7 edl tool because the axon7tool with minimal adb wouldn't work since it never recognized the phone in adb mode and it was a mess with the drivers.

now it is working with gapps, but yesterday all the apps updated themselves from the google playstore, is this behaviour normal? or am i supposed to keep the gapps not updates and install every new app from alternative appstores?

and my camera is not working since the camapp updated itself as well. i'm trying Google Camera by Urnyx05 now, which version should i take?

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] raystef66:
Hard to tell and depending on your personal usage.

Since I'm not that long on the same ROM due to building and testing I can not judge to the batterylife performance in depth.

But imo the batt stats would likely be the same on average on stock kernel.

I like Viper the most but happened to test crDROID since yesterday and since I like customs a lot, crDROID (and RR) offers quite a lot of these too ;)

But as said it's up to you to test.

Btw, testing new ViperOS 6.7 as we speak ;)

I am new to the Axon 7, have used the LG G5 before with custom roms.

I tried installing ViperOS and RR on the Axon but both times it failed becuase of "Error 7". Quote:

Something to do with verifying that the OS ist suited for my device. I searched for the problem, and found that you can delete some lines of code to surpress this check. I did that but device wouldnt start.

I unlocked the bootloader following THIS and installed TWRP 3.3.1-0 .

I read something about a Universal v2 Bootloader and a modem that needs to be installed. Don't know what is meant with that. Found THESE files but do not know what to do with them.

You should use TWRP 3.2.1-8 Treble and create a vendor partition with the PARTY Tool first. Then flash the Universal V2 Bootstack, the modem for your Axon 7 version and finally the ROM and Gapps

Second, is there any way to swap the recent and back bottons? Been used to the otherway around from former roms.

There seems to be no integrated way, and apps from playstore get me a delay. Haven't found a magisk module either.

Thx in advance!!!

You're welcome!

You can use this : https://xdaforums.com/axon-7/themes/mod-soft-key-reverse-using-synapticsdsx-t3827574

There's a module that reverse it to recent/home/back

Or take the DF!NR to choose which way you want it.

But afaik I reversed it already to RECENT/HOME/BACK by default. If you want it reversed back to BACK/HOME/RECENTS use the DF!NR zip and flash it (do mount system and vendor)

The MAC address issue should be fixed in all ROMs by now , if you still had this issue try going /persist directory using root file manager and find how many wifimac.dat you have , if two available (wifimac.dat , wifimac2.dat) check the one which have the correct address and copy it to wifimac.dat then remove the other file.

Any Guide to resolve the Error 7 issue on installation process?

Hi raystef66,

I've tried to install this ROM, migrating from AospExtended ROM v5.8.

I've followed the installation direction exactly but get stuck with Error 7 on installation process.

I've even tried the vendor boot combo but the results are the same with Error 7 issue.

I think the vendor size of AospExtended ROM v5.8 is 800MB.

Could this be the reason? or other cause?

Can anyone kindly provide me a hands-on guide in order to resolve this issue?

Big thanks in advance.

wifimac.dat file error...

Hello raystef66, I believe you, must be problem with my phone. Still on 8.14 build. Didn't try your latest yet. Noticed on your previous build that you said problem was fixed so wanted you to know that I was still having the random WiFi mac address issue. Noticed today that my /persist folder only had one wifimac file in there labeled wifimac2.dat. Had same wifi issue before on different rom lineage os15.1 unofficial by armitage. Any precautions to take before I flash your latest? Should I just delete the wifimac2.dat file that i relabeled to wifimac.dat from /persist folder before next flash? Will your ROM place the correct file in /persist folder or is it Coming from somewhere else? Thanks :D

First try ray latest build , do as I said about the permission , note what inside the wifimac.dat maybe its just rubbish and not an actual address, you can use the address in my previous post.

After that check the mac address, it should read the correct address if it did then it will stick even after reboot.

Note : Don't touch the persist directory unless you have a good backup

WiFi Mac address changing on restart-SOLVED!!!

Hello [MENTION=4896610]king1990[/MENTION], you figured out my problem. Was 2 issues.

First was wifimac.DAT file was renamed to wifimac2.DAT in /persist folder.

Second was permissions on the file were not correct. See screen shots attached Was not able to look at file contents but was able to use 3C all in one toolbox to change permissions from rw------ to rw-r--r--. See permission notations under file in before and after screenshots attached. Mac address did change one more time after the first restart but has been persisting on all other reboots since!

I will flash [MENTION=5334294]raystef66[/MENTION] latest viper ROM update tomorrow to see if Mac is still sticking.

I have no idea how the file got renamed and permissions changed but appears to be fixed now. Wonder how many other people are having the same problem as me and think it is a ROM issue? Thanks to everyone's help to solve this issue. Love this ROM :D

Tips for installing the viper ROM 9.0 OS from AospExtended ROM v5.8

Hi raystef66,

Thank you so much for your great works on your 08.18 viper ROM.

Migrating from AospExtended ROM v5.8 (OS 8.1.0) to the viper ROM, I followed the installation direction exactly but stuck with installation process error, just stopping in the middle of the course. Well, this hurdle was resolved simply by reducing Vendor size to 512MB from 800MB with party tool. Installation went on well without stopping.

When the system booted, the initial screen came in with a "system corrupted" message., but still went on booting process ok as normal. This error message, however, persisted at every booting. it seems that the installed 'UniversalBootstack_v2' had a conflict somehow with previously installed A2017X_BootStack_O_B12.

Reinstalling the viper ROM with A2017X_BootStack_O_B12, Voila! the installation process went on and completed very well without an error. No more error message appears at times of booting! It runs really well with every functionalities, so far experiencing no hiccup. Thanks all to raystef66! Long Live, raystef66!
