[Xiaomi Mi A1 Questions & Answers] stelariusinfinitek:
I was afraid too, now I'm on Nougat :))

Just follow this tutorial : https://xdaforums.com/mi-a1/how-to/tutorial-downgrade-9-0-to-8-1-edl-imei-t3879624

Before doing anything, boot TWRP and create a full backup of your system, after that transfer it to your PC. Probably you don't need it but better safe than sorry.

After you will flash March firmware, your phone will boot but you will not have signal, it's okay. Thing is, you don't lose the IMEI, it's still there, but somehow you lose the signal. Boot TWRP again, create a backup of your boot and EFS, you will see TWRP folder in your phone, go there and you will see a backup. Remove your backup files and replace them with the one from the guide, then you can restore them without issues (you will see a modem error, ignore it). Restart and let it boot a bit, then go to bootloader again, flash March firmware again (don't flash the November one! ignore that from the guide) and the signal will be back. If you do this, I doubt you will lose your IMEI somehow. I never lost mine, it's the same from the box.

Good luck! Make sure you go in developer settings after and disable automatic updates or you will be back to Pie. I rooted my phone so it can't update.
[Xiaomi Mi A1 Questions & Answers] Nafis-ul-Islam:
Just flashed it now, and it's working perfectly as orma1 described. I can't thank you enough <3
[Xiaomi Mi A1 Questions & Answers] orma1:
I'm happy to help :)

but all the credit goes to rizkyxculture for finding this method and ibooth2004 for correcting us to flash March update again instead of the November one.
[Xiaomi Mi A1 Questions & Answers] Marcos OC:
so glad i read this and got the courage to go back, now downloading november ota, pie on this device is so bad, and cant even use gcam.
[Xiaomi Mi A1 Questions & Answers] orma1:
I agree the system's performance on pie is horrible and also the mic volume is low which is very annoying.

I can receive the files and than use send more option to send files. But if I use send feature than I cannot connect the user indefinitely. Same goes for Android beam and one plus file manager file transfer. Does anyone have any idea what causes this? I had this issue from day one (one month) fr purchasing this device.
[Android Q&A, Help & Troubleshooting] NaMkCaH:
Hello,

I ran into some troubles with a chinese tablet. I then flashed STOCK OFFICIAL firmware from their site many times. Everytime i flip it, it still have display upside down.

The touchscreen is not reverted or anything, works fine, but the display is reverted. (whatever orientation i try, the top of the screen display is down etc)

1/ Is there any adb command i can use to reverse accelerometer maybe? (im rooted)

2/ I am able to modify the .img firmware with DragonFace, what flag can i maybe modify there to fix the issue? (sysconfig1.lhs? buildprop? init.rc?)

thanks for your time guys.

Same problem with a number of ROM's. The only ROM I have been able to flash is an old wm5 (ART_HTCDAN_11240301_026790_DAN_SHIP). And I think it is an older version than the one installed when I bourght the device :(

My p3300 refuses to do any flash from win7, sometimes it can't see the device and sometimnes it reaches 2-3% of the transfer before it stops.

Shouldn't be too big of a deal

Pretty sure it's an antenna. You may notice no difference in the functionality of the phone if I'm right, or it'll just have weaker signal for cell/wifi/gps/blutooth/whatever the hell the thing was for. Without ripping mine apart I'd have a hard time telling you more specifically.

What's Working?

Telephony (Calls, SMS, Mobile Data)

WiFi

Bluetooth

NFC

GPS (Plain Device Mode Works)

Fingerprint

Camera (Needs Improvements)

​

What's not Working?

Obviously Samsung's own features such as Samsung Pay, KNOX, Theme Center, Game Launcher, etc. won't be ported to LineageOS. We may have our own implementation to similar functions, though.

IMS services (VoLTE, VoWiFi, etc). Samsung has their own proprietary implementation. It is not really possible to easily port that to LineageOS.

HWC

​

How to Install?

Make sure TWRP has been installed and functional.

Download the latest build (and optionally gapps).

Reboot to recovery

Wipe data and cache (required if you switch from other ROMs)

Flash the latest build (and gapps)

Reboot

I'm just here to say that this is the best ROM all-around for the S6. Also calls do work now on my G920T. <3
[Galaxy S6 / S6 Edge Unified Development] olanie:
Aside the Marduk ROM(nougat), this ROM is by far the best Pie ROM on my g920t, I have been using this for few days now, and it has been great.

With little tweak here and there for specific concerns this is cool.

This Pie ROM can actually make calls audible at both ends!!!

Thumbs_up to the developer!!!

[Galaxy S6 / S6 Edge Unified Development] moosebreath:
How is the camera on this ROM? Is the call echo present? Thanks!
[Galaxy S6 / S6 Edge Unified Development] OttawaNurseM:
I'm on a G920-W8 and this rom works very very well. The camera is much better than the Lineage 16 version I was using (and it's actually useable) and I made a few calls and there's no echo.
[Galaxy S6 / S6 Edge Unified Development] tillward:
From the first few days testing on Viper OS:

-Calls sound better.

-Device stays cooler.

-More Rom options. Colours, status bar etc.

-Default camera works, but video crashes and 3rd party apps like Mobike can't focus.
[Galaxy S6 / S6 Edge Unified Development] thebrazilian:
Does this ROM pass Magisk SefetyNet check? I'm stuck failing ctsProfile. I already installed the MagiskHide Props Config, but no luck. Is it supposed to fail?
[Galaxy S6 / S6 Edge Unified Development] tillward:
It doesn't pass the cts profile as it's modified. Use Magisk Hide Props Config.

Used to run fine for me and pass cts afterwards, then it became a bit more complicated, so I suggest following the tutorial in the xda thread.

https://xdaforums.com/apps/magisk/module-magiskhide-props-config-t3789228
[Galaxy S6 / S6 Edge Unified Development] thebrazilian:
Definately doesn't look simple to me. After trying to spoof fingerprint (opening a terminal and selecting galaxy s6 fingerprint), I now got stuck in a start loop (white viper symbol just keeps moving its tongue).
[Galaxy S6 / S6 Edge Unified Development] tillward:
Exactly the same happened to me. I didn't bother reading all the extensive tutorials, so my fault. I will try again when I have more time.

More info here:

https://github.com/Magisk-Modules-Repo/MagiskHidePropsConf#matching-the-android-security-patch-date

The security patch level for this rom is listed as 5 April 2019
[Galaxy S6 / S6 Edge Unified Development] thebrazilian:
So I guess it shouldn't be considered a big deal failing the checks? If more knowledgeable aren't able to make these S6 ROMs pass, then a newbie like me definitely won't.
[Galaxy S6 / S6 Edge Unified Development] Didgeridoohan:
Creator of MagiskHide Props Config here...

If not passing the SafetyNet CTS profile check is only because of the ROM device fingerprint, the module can help with that. And it's not very complicated...

Run the props command in a terminal emulator.

Pick the "Edit device fingerprint" menu.

Choose to pick a certified fingerprint.

Pick the fingerprint of your choice.

Reboot.

That's it... If it doesn't work there's something else going on, and if someone's experiencing issues please feel free to post Magisk and module logs in the support thread. I'm always happy to help if I can.
[Galaxy S6 / S6 Edge Unified Development] thebrazilian:
I did just that (actually also enabled "improved hiding"), but for this specific ROM (also tried same procedure on Marduk Stock ROM for Galaxy S6), I get a permanent loading screen when I reboot. When I tried on Marduk's ROM, there was no permanent screen, but the test failed (since it was already failing basicintegrity, I think your program wouldn't be able to help anyway, as it was said on your page). Thank you for your creation, though!
[Galaxy S6 / S6 Edge Unified Development] tillward:
That process worked for me on previous builds of LineageOS 16 for Galaxy 6, but had bootloops for last few months, when trying.
[Galaxy S6 / S6 Edge Unified Development] Outlaw Dragon:
What's different about ViperGapps?
[Galaxy S6 / S6 Edge Unified Development] avidichard:
Yep, another Pie OS with still the same problem as Lineage OS 16. The freakin' camera just does not want to work. When recording a video, the sound is WAY TOO low. When taking a picture, the flash does not syncronise so picture is always dark. Basically, the flash goes on and then the picture is taken once the flash is out. I also had some update issues at the beginning when initially configuring the phone right after connecting to my WiFi network. LineageOS 16 stopped having this weird issue of needing to go back and start config again. This ROM still has this customization annoyance asking you to change your wallpaper when you clearly said to never mind, it reminds you until you go into the options and ask it to stop notifying you. It also comes with what I consider somewhat a slow start screen with a Google Search bar when I did not request one, slow animations. I need to admit that the ViperOS options are a good thing but again, it denotes a third party installation in there which I disaprouve as I just want a clean OS with the simple basics and let ME do the third party installations.

I have aCanadian W8 phone, I consider this ROM equal to Lineage OS 16 as nothing has changed between both besides ViperOS additionnal features and wallpaper. I'm always opened for testing new Pie ROMS but for now, none of them are quite ready for serious use.

Good things: ROM installation is a breeze and goes through perfectly, that's about it for now. Oh! And it's compatible with W8 phones which I surely appreciate!!!
[Galaxy S6 / S6 Edge Unified Development] bushladen:
The main diiference is the fact that on viperOS calls works on W8.... ;)

Hi,

I just started to run ViperOS on my S6 a few days ago, switching from Ultimate Oreo), and I'm rather impressed:

- the system seems stable

- battery usage is very good (comparable to Ultimate Oreo)

- Camera works fine

There are two things not working well

- the fingerprint sensor is not working as good as in Ultimate (slower and sometimes not working at all)

- graphics speed is way lower

thanks for the efforts!
