I seldomly use GPS, it seems good. But mine should be the same as phhusson's v22 (if he released v22 lineage), so it should provide no better results.

So is the other gsi like rr gsi?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] notsyncing:
I don't quite understand your question.

If you mean the flashing procedure, yes, GSIs are all flashed this way, but you need to wipe data if you are flashing a different GSI.

If you mean the GSI is something other than lineageos, no, it's lineageos.

Can any1 please confirm to me if ambient display on this rom is working on the mi mix 2s??? Because i learned the screen doesnt support it !

You need to install Xposed framework and Enable Ambient Display module, but yes, work

Yes, we have Mix 2S Kernels sources and now Snapdragon 845 Sources, I'm not surprised that some devs are already working on our phone
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Ultra_HR:
Just feel like it's unusual for work to be done on an official lineage build before we really see any activity on XDA (aside from this one thread)
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Bryandu13:
True. But you know OnePlus offered their OP6 phones to lot of recognized devs on XDA for custom rom development, I would not be surprised to see Xiaomi doing the same.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Saiger:
Xiaomi will never start doing that. It would ruin their business model.

This. When it comes to phones, they make money only off of their software.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] notsyncing:
This may because that it's on a very early stage. I compiled a boot image from offical lineage repos for mix2s and it did not boot (stuck at boot animation). Let's be patient and wait :)

I also got some random reboots these days, after I updated vendor and firmwares latest MIUI 10 version. Maybe this will get fixed in coming MIUI versions, i guess...

What makes you say that by the way?

Don't want to hijack this thread by any means, but all I can say is that I was actually starting to work on this device (the device tree is already public and pushed to LienageOS github). Unfortunately for me, last week it died and I had to send it back for warranty. Sadly, I'm not sure when and if I will get the replacement.

So I tracked down the cause in my tombstones, it's issues with ipacm and 2 missing .so

Went to report the issue and saw you beat me by a day ;) for now I just disabled hardware acceleration for hotspot. Waiting for another build to release because I just formatted my SSD and don't want to resync sources again just to build
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] notsyncing:
The hotspot issue is being worked on at https://github.com/phhusson/treble_experimentations/issues/131. It should be ok in next release :)

In fact the hotspot was working on the first release (v21), but stopped working in v22. I did not use hotspot, so until some people are reporting the hotspot issue in this thread did I notice this bug.

This never happens on my device. You could try updating your vendor, kernel, and firmwares to latest MIUI dev version (exclude system from stock zip).
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] aeppacher:

Thanks for your work. Is SELinux Enforcing on this build?

Update 1: Just installed and the answer is yes, SELinux is Enforcing.

Just a note, I ended up using a flash_all.bat script to get back to stock to make this work. I flashed back to stock everything, then installed the system.img via fastboot, then flashed TWRPv8 via fastboot and booted into it to clear cache. Then flashed open_gapps pico and Magisk. Got crashes during setup, so I went back in as OP recommended and wiped Data in TWRP. That seemed to have worked.

Update 2: Camera app works, but no 4k recording.

Update 3: Bluetooth audio seems to be coming out of the speakers (issue with all the GSI ROMs on Mix 2s so far). Other party hears an echo when I use speakerphone.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] alexep:
Do you mean that happens all the time or only when using bluetooth audio during calls?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] notsyncing:
Thanks for your testing! For the bluetooth audio, I listen to music through LDAC every day, and never had this problem. You can try reconnect your bluetooth device and see.

Anyone else getting a BUNCH of random reboots? It'll be in my pocket and ill take it out after an hour and it will be needing to be unlocked from reboot. Can send logs if needed.

I have the Bluetooth problem as well. I have Sennheiser Momentum IEBT, which I use as a headset. Whenever I try to call somebody,or someone calls me, the sound comes through the phone's speaker and the other person reports an echo.

Update: Regular audio works fine, but AptX doesn't work out of the box, installed a module from Magisk for that.

But that's not the main problem, aptX can be patched in. The main problem is that I can't receive phone calls on my BT headphones, the sound comes through the phone's speaker.

---------- Post added at 03:58 PM ---------- Previous post was at 03:50 PM ----------

sorry noop question,,, can I follow the instruction here

to install notsyncing rom ??? .

thanks

---------- Post added at 04:07 PM ---------- Previous post was at 03:58 PM ----------

last question guys sorry,

phhusson V23 update has in the change log the following :

- Add an off-computer flasher (first step towards OTA)

does that mean after a couple of more updates OTA will be ready for GSI ROMS ?

I'm asking because if yes then I'll wait until it is ok then I'll start flashing, better than needing to flash all the way again just because of OTA enable

now really thanks :)
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] notsyncing:
1. Mine has no difference with his, except in v23 mine contains an audio fix. phhusson did not release v23 lineage yet.

2. Flashing instructions are the same.

3. I don't know about OTAs, you can ask him for details.

Sorry out of the topic, since I'm using xiaomi mi6 i always using custom kernel with feature fast charging 3000+, and i see in this rom include that feature. Nah.. can i get ur help for making custom kernel MIUI or non-MIUI roms with feature quick charge up 3000+?

Because i hate stock kernel so slowly for charging (up 2 hours 0-100%). T_T
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] notsyncing:
In treble roms we just use miui stock kernel and the quick charge works out of box. Currently I don't know if there was any specific driver in kernel handling quick charging. You could ask your device maintainer of your custom rom for help.

This rom is the only one with which I am able to get audio through headphones, which is a plus. The con for me is that I cannot get mobile data to work, something that works fine on the RR GSI rom for example. I'm fairly new to Android so this may be a thing that is known and easy to fix, so I hope someone can give me some directions. Wi-fi works fine. If I have to choose between correct audio output and having mobile data, the latter one will have to win for now.

[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] uodenim:
I use 4G where available, but in my home town the connection usually falls back to HSPA/HSPA+. I read on Wikipedia that those fall under CDMA so that may be the answer then. Is there any particular explanation for why this ROM does not support it? Or is it a LineageOS thing, and should I write off Lineage usage? Cellular data works fine on Resurrection Remix, so I'm kind of curious to find out what causes this difference.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] notsyncing:
You could try playing with the network settings in *#*#4636#*#*, and see if any combination worked.

Cdma doesn't work, just LTE for Verizon and Sprint. Flash latest miui global stable before flashing this. It will solve your issues.

[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] uodenim:
Thank you very much for the suggestion. I don't know why this works, but it does. I did have the 9.6.4.0 vendor flashed before but that apparently was not enough. What I did now was

Format

Install MIUI Global stable (miui_MIMIX2SGlobal_V9.6.4.0.ODGMIFD_c629d9b1c1_8.0.zip).

Boot the phone and wait for confirmation of the 4G/LTE indicator.

Use fastboot to flash the ROM from this thread to system.

Wipe cache and data and such.

Boot again, confirmed cellular data working.

After that I resumed with NanoDroid patcher and MicroG to finally get what I wanted: As little Google as possible with a close to stock Android ROM and (BT) audio working correctly :laugh:

Probably way off-topic and please let me know if this is unwanted

What I do not understand, however - and maybe someone can enlighten me - is why I cannot get Magisk + MicroG via NanoDroid to work. Installing Magisk works fine, then using NanoDroid patcher for signature spoofing and rebooting works fine as well. Installing MicroG via NanoDroid however results in a slow boot loop, easily fixed by running NanoDroid uninstaller. I don't have any immediate plans for Magisk, but it's nice to have options :) I get the same on other GSI treble ROMs, by the way.
