Development [ROM][12.1][UNOFFICIAL] LineageOS 19.1 for Xiaomi MIX 4

[EnzoG54]

Hello, just flashed 19.1 LOS, awesome rom, very smooth. However, is there a fix for Netflix to detect L1 Widevine? Or I'm stuck at L3. Thanks..

Hello, I would like to know what the current quality of the selfie/front facing camera is?

And does Gcam now work perfectly (especially in the selfie department) like the ANX camera app?

I had problem with proximity with another ROM and it was due to wrong firmware.
I had xiaomi.eu beta flashed before.
But after flashing Chinese stable firmware (no wipe or anything needed, just sideloading through adb sideload) it worked flawlessly

Maybe that fixes your network issue as well. I don't have 5g contract so i don't know

Thanks for the input. I did reflash the firmware, no change. I downlaoded a sensor test app and noticed a pattern. As long as there is no audio playing the test in the app works perfectly. But as soon as there is audio coming thourgh the top speaker, the ultrasound proximity sensors works 1/25 times and is really unresponsive. So i guess it has something to do with an audio route issue. Also i have to restart the test app so it reinitializes the seonsor, so definitely sounds like a audio route thing

I went through the logcat when starting the test in the working and non working usecase. The only two things different are the sensor initializations:

New builds with May security patch are up. ANX camera is now default camera solution. The SE policy rules for ANX have been rewritten and now almost everything is working correctly, including the downloadable features like Panaroma and Document scanner. The only things not working are slow motion video recording and HDR video recording.

Download links:

• Vanilla build
• Gapps build

@0201m Thank you for the logs concerning proximity sensor, I'll look into it. The sensor was working correctly on 11 and 12 and I haven't done any major changes to my device tree so something must have changed in 12.1 to cause this. Also I fixed the screen animations to line up with physical buttons so thanks for letting me know about that too

Thank you for the update! If you need additional logs just let me know.
I experienced another side effect of the non working proximity. I have AOD enabled and somehow even without anything playing and the proximity theoretically working the phone wakes up in my pocket and starts random inputs.
So the "check prxoimity in doze" somehow doesnt work. i believe there once was an option to enable it under display settings, but its not there.

 

[0201m]

Oh anothter question. How do i update on lineage? Can i boot into twrp and dirty flash even with an encrypted data partition? I guess it should work as data is not concerened in the update process.

 

[lightskreen]

Thank you so much for making this room, it's very good. My only nitpick is I wish the status bar height was a little more uniform. Is there a way to make it so it looks more like the notification shade clock and icons?

 

[er453r]

@Inkypen just dirty-flashed the lineage-19.1-20220511-UNOFFICIAL-gapps-odin build and everything that was working still works great Two issues already noted in this thread:

1. ANX downloadable features still do not work for me (I get the "network error" massage)
2. I have the same proximity issues @0201m reported, and probably had them before all along, just did not notice them (phone can go crazy in the pocket or during a phone call from face touches - I just blamed it on xiaomi hardware )

Someone else asked me this so I'm just going to copy/paste the reply:

Sideload is one way to update but it seems that TWRP won't sideload some A12 ROMs. I built OrangeFox for myself and I haven't had any issues with sideload.

The other method you can try is to use adb to copy a ROM to the phone and install it directly from the device. Internal storage isn't actually mounted because of encryption, so /sdcard becomes attached to a temporary filesystem in memory. You can take advantage of this, for example:
adb push lineage.zip /sdcard

Very strange, ANX downloadables are working here. Try this sequence to see if it works:
Enable USB debugging and ADB Root/rooted debugging in developer options
Connect device to a PC and use a terminal window to enter these commands
adb root
adb shell setenforce 0
This temporarily disables selinux. Try to download ANX features. You can just reboot device to re-enable selinux.

Also good news, I've managed to fix the erratic operation of the proximity sensor. Fix will be in next update.

Would you mind sharing the steps you followed in order to dirty flash ?

lnkypen, I just flashed thim, ehm, quick question, is it normal that before this update I truly couldn't see the "camera hole" and now I can ?

Also, I no longer have root, sorry, first time dirty flashing, not really sure what to do.

 

[er453r]

Would you mind sharing the steps you followed in order to dirty flash ?

@santimaster2000 I do it in 4 steps:

1. Temporarily flash twrp from Inkypen in fastboot with
   1. fastboot boot twrp-odin.img
2. Push the zip to data with
   1. adb push lineage-19.1-20220511-UNOFFICIAL-gapps-odin.zip /data/
3. Install with TWRP without wiping anything
4. Restart to system

@Inkypen tried it exactly as you said, but the same - network error

Did it, but wiped dalvik/cache, everything seems to be working, aside from root, also, for some reason "Phone Services" keeps making the location green notification thingy pop up.

 

[santimaster2000]

OK, got root, problem seemd to be that I was flashed the first patched boot.img that I got from the stock MIUI ROM, I extracted the new boot.img from the latest LOS build, patched and flashed that, now I got root.

I still have the problem with "Phone Services" constantly accessing location, and also the front camera "hole" seems to remain open all the time.

 

[Inkypen]

@Inkypen tried it exactly as you said, but the same - network error

Not an selinux issue then. It's working fine here on LOS and on PE. Go to app info (long press anx icon on launcher and select the "i") clear all storage and try again. If it still doesn't work then I'll need a logcat to try and troubleshoot it.

Kinda sounds like the issue I had early in development when various things work on one boot slot but not the other. Reboot to recovery and flash MIUI 13 firmware again.

Also, why does everyone seem to extract and patch the boot image when trying to install Magisk? Why not just sideload it in recovery?

For future builds the relevant latest firmware will be included in the ROM zip, to avoid all these headaches about firmware version.

Are you talking about the camera thing or the location thing ?

So, I just flash this firmware, right ?

[Firmware] Xiaomi MIX 4 [odin] [Auto updated!]

Xiaomi custom ROMs users face a problem with firmware updates. As there are many devices with no one to provide the newest firmware update every single release, and developers who provide updates to devices may forget or be busy sometimes, so...

forum.xda-developers.com

Thanks again for all your work man !

 

[Inkypen]

New builds are up. Firmware is now included so no need to flash it separately.

• Erratic proximity sensor fixed
• Kernel upstreamed to 5.4.195
• Firmware/vendor blobs updated to MIUI 13.0.6.0

Some people are having issues updating/sideloading via TWRP, so I made an unofficial build of OrangeFox.

https://sourceforge.net/projects/xiaomi-odin/files/OrangeFox-R11.1-Unofficial-odin.zip/download

To install it simply sideload it in TWRP. Occasionally the device won't get recognised when plugged into a PC and it's simple to fix. Go to the mount page in menu options (3 horizontal lines) and toggle MTP off/on.

Regarding updating the ROM, there seems to be some confusion on how to do it because no recovery is currently able to decrypt A12 data partitions. I mentioned it earlier but there are two ways in which to update.

• Sideload

This is the simplest way to update but it seems that TWRP won't sideload some A12 ROMs. If sideload doesn't work then use the OrangeFox linked above.​

Usage:​

Connect device to a PC and activate ADB sideload mode in recovery​

In a terminal type : adb sideload rom.zip​

• ADB

The other method you can try is to use ADB to copy a ROM to the phone and install it directly from the device. Internal storage isn't actually mounted because of encryption, so /sdcard becomes attached to a temporary filesystem in memory.​

Usage:​

Connect device to a PC​

In a terminal type: adb push rom.zip /sdcard​

Install zip in directly in recovery from internal storage​

You should replace rom.zip with the filename of the zip you want to flash. Because of the virtual A/B setup on this device it appears that addon.d is no longer functional and this means anything that modifies the system will need to be flashed again once an update is completed, a prime example being Magisk (which you can sideload, no patching boot image is necessary). OrangeFox even prints a helpful message reminding you of this little fact.

Will flash as soon as I can make a proper backup of EVERYTHING !!!

Quick question, if I'm dirty flashing, should I wipe dalvik/cache or not ?
