In 19/01

I have problem with in-call sound when I use earphone.

The sound that I receive is really really low even the sound is full.

Is it known?
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Richard_10:
Hi, can you update to the latest version and recheck please.

Also can you confirm that you installed the right Miui firmware version before flashing this rom ?
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] prefor:
Wait... Did OP account get disabled? :eek:
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Richard_10:
Weird..

What's going on??
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Norton_Sec:
[MENTION=9222803]gringo80[/MENTION]

I tried dirty flash but I got an error was like this: system_root (invalid argument)

Finally I wipe data dalvik chache system

And reboot

Then this time I didn't get error and I flashed everything base on dirty flash.

Now it's good.

Earphone has been fixed in 31/01 but I think it must have higher sound incall.

And yes be sure I on right firmware.

A question:

Does VPN setting open for you?

For me when I try to open it, redirect me into main setting.

Hi master! Any news of PixelExperience ?

I hope you have time. Thanks

Hi .

Ad. 1. You have to be much more detailed , else no one will be able to help you with this .

Ad. 2. The restart to system before installing magisk is a cure for dirty flash in my opinion .

Ad. 3. This can be fixed in the 20200127 version .

Ad.4. When I open it I see empty screen with information about no added vpn networks (19Jan2020 version).

4.This happens for me when I try to open VPN setting

And about 1.

Actually what I did somehow was clean install but for next update if any error happens I will take an screenshot.

[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Tomek0000:
The answer from gringo80:

For those asking for the Security Patch Levels, the original date is maintained to match the same date for the firmware. It is required to pass SafetyNet !

Don't worry, you are using the latest SPL from January !

Hi,

How its a procedure for install this rom? I have now miui 11

1. install this fastboot firmware (this procedure remove my twrp 3.3.1, which i have now ?)

2. reboot, install los 16

and next steps from OP

thanks.

I'm about to make a dirty install, but I have a question. I already had magisk installed. After flashing the build, why do I need to flash magisk again if it was installed before? Does it no longer work after flashing a new build? Sorry for the noob question.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Tomek0000:
Magisk do something with system partition. If this partition is reflashed, it has to do it again.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] ezraravin:
If anyone gets a "failed to mount system (invalid argument)" error in TWRP while flashing the build (already saw someone post something like that in the thread) and could not fix it by wiping everything, here's what worked for me: boot into fastboot and type "fastboot format system". This essentially saved me from a bricked phone. I hope it helps others too.

Hello! I need call recording, i can use it because the factory what 9 lite doesn't allow? My phone eu. global. mimu 11. And need a "band 20" if you can.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Tomek0000:
A you asking because native dialer from xiaomi is able to record ?

It is changeing . Xiaomi informed about using google's dialer in all future releases.

LOS will never add this functionality to it's own dialer because it can't .

I bought specific application from google play for this functionality . It worked in android 6 and 7 , but from 8 problems started (sometimes worked , sometimes not) . Today android api and play rules castrate this app and I am not sure if t is able to record anything. Only old versions could .

Band 20 is supported by drivers and hardware in mi 9 lite as a difference to the china version of this phone. If you have lite , you have it suported for free .

will try it again
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Richard_10:
Yes it's a tricky step indeed. But once you succeed, the result is worth it, because in that way the dev kept the device signature. So all DRMs and stuff are working + safetynet.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Tomek0000:
Safetynet is correct but ctsprofile and basicintegrity both are false. Do you have the same?

...and have to install again gmscore after each phone restart.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Richard_10:
None of this is correct.

1- You should be able to install gms once (maybe twice)

2- safetynet : basic integrity + cts profile should pass (I am sure it dosen't for you because somehow you don't have gms correctly installed)

My advice.

Verify that is is well installed as a system app (priv-app).

Force close gms and play store and erase their data.

Reboot into recovery and wipe cache + dalvik , and erase the folder /data/resource-cache.

Reboot

Install gms (normal installation), install play store (normal installation)

Try to connect your account.

Hope it helps

Maybe it's my carrier that has low signal in my area, 4G speed is normal the only problem is the network bar drops constantly (switching towers all time). I will try to live with that.

I want to clarify that in miui this does not happen. (Sorry my english translator).
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Richard_10:
Technically, this is a treble Rom (with bug corrections). So it relies, by nature, on the same HALs (standardized due to treble rules imposed by google) as MIUI. It even uses the same kernel as MIUI.

That is the same reason why basically everything is working. There is no adaptations or generic HALs ... All is stock.

We have a battery that is comparable to MIUI for instance, which you would never get on dedicated LOS ROM.

Now, my guess is your MIUI firmware is more recent than the one this rom is flashed upon. So maybe xiaomi updated the vendor and kernel to have vetter signal in some situation, that's all.

The best comparaison would he to test your signal with the miui firmware [MENTION=236558]Gringo[/MENTION] asks us to flash before this rom.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Tomek0000:
It looks it helped. I:

1.Removed data and cache and uninstaled play.

2.Removed google account from main setings.

3. Gms. Not trivial. I used app2sd. Removed data and cache. Disabled gms. Removed gms.

4.Removed /data/resource-cache, wiped cache and dalvik in TWRP.

5. GMS

A.Installed it. Set all privilages to on.

B.Opened firewall.

C.Removed all restrictions in XPrivacyLua.

6. Play.

A. Installed it. Set all privilages to on.

B. Opened firewall.

C. Removed all restrictions in XPrivacyLua.

I meant all animations. Just search remove animation from the setting. Weird, because I added a lot of fingerprints without any problems! It's possible you have a firmware problem or a glass protector problem, I don't know.

One thing is ommited in OP. You have to wipe system and vendor before installing LOS.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] JimmyBondi:
and another thing is wrong in OP:

- Wipe Data, then go to /data and delete everything except /media folder.

When you delete everything in /data, you will delete files which are needed for decryption to.

So you have to format data again.

So could you write the whole steps please?
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Tomek0000:
OK.

1. Unlock bootloader.

2. Install stock MIUI Europe version with android 9. Enable adb in developer options.

3. From the console and usb cable :

adb reboot bootloader

fastboot erase recovery (only if next line will have problem)

fastboot flash recovery nameRecoveryFile.img

fastboot flash vbmeta vbmeta.img

fastboot reboot (press Vol+ and go to TWRP)

4. Wipe - Format Data

4a. Install fstab.zip only if you want to start MIUI

5. Wipe : cache, dalvik , system, vendor and manual remove /data/resource-cache (and wipe Data if it is not dirty install)

6. Install custom rom and restart to TWRP

7. Install Custom Google Pack and Gcam , wipe dalvik and cache, restart to system

8. Install play store from apkmiror and set privilages and add to battery not optimize list .

9. Install again gmscore.apk from Custom Google Pack, check privilages .

10. Add google account.

11. Restart to TWRP install magisk , restart do system, install in magisk (if you need it) : riru_core, restart , riru_edexposed yahfa, restart.

If play store does not work :

remove google account (it can need to remove screen lock)

delete cache and data of play store and google play service

reboot to TWRP , Wipe dalvik&cache and delete /data/resource-cache

boot system and reinstall gmscore.apk from Custom Google Pack, check privilages

add google account
