[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] toscha42:
Just installed Alpha 2 and I'm pretty satisfied. Some observations:

- GAPPS Pico from OP couldn't be installed, in TWRP 3.3.1-0 installation ended with 'Error 25'. Installed GAPPS Pico from Cyanogen instead.

- Fastcharging is working fine with the original charger.

- Fingerprint is working seamlessly.

- NFC seems to work at least the symbol is available. Haven't had a chance to try though.

But. Am I just too dumb to find or is there no option to active Doubletap-2-wake?

Cheers

May I ask where can I find the download for "cepheus-user-10-QKQ1.190825.002-V11.0.7.0.QFAEUXM-release-keys firmware" ?

I have tried to search but nothing is clear to me.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] tomzzi:
Will try.

This is the one? https://github.com/Official-Ayrton9.../releases/download/r26/Quantic-Kernel_r26.zip
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Yes, that should work :svetius:
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] tomzzi:
Thank you.

Flashed. Will report back after day or two. :good:
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Just uploaded a new developers version (pa-quartz-5-cepheus-20200827-dev-quantic.zip) into the mega folder at https://mega.nz/folder/75IHSCZb#gYkiCuQaV4grDAaBpSbqyg

This version was built with the Quantic kernel (from the QK-Inline sources) and the latest PA tree.

It is obviously experimental, so some things might be broken although I hope it all works :)

Double tap to wake is working here too (usually doesn't with the flashable quantic kernel on PA).

You can dirty flash to this version and back to the other one (August 21 DEV) if you have any issues. Wiping the caches is not necessary.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] toscha42:
A first 'smoke test' after dirty flash doesn't reveal any bugs so far. Dt2W works fine otherwise I'd have reverted immediately back to 20200821. :)

Don't know what might be the advantage of Quantic kernel but at least it doesn't seem to do any harm.

Cheers

[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] nmlssit:
I'm getting ctsProfile: false in magisk on quantic build, idk if it's relevant.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
I'll definitely need to look into that in case we should decide to use this kernel for the official version. It should pass safetynet including CTS without magisk.

Now if you do need it to pass for your banking apps or google pay, you can use the hide props module in magisk. I always use that and magisk hide and never have any issues with gpay and safetynet.

Just install the magisk module, open a terminal using terms for example and get root with su, then say props and configure the device fingerprint

---------- Post added at 09:50 PM ---------- Previous post was at 09:45 PM ----------

In the meantime I've tested all that I can test, gpay/nfc, bluetooth, voice activation, gps, vowifi etc and it all seems to work well.

The advantage with this kernel is that it is currently the best maintained kernel for the Mi9 and the dev is putting a lot of work into it. And hopefully it will bring even more stability to the device.

I'm still not convinced all the stability issues of the past are ironed out and the kernel change may be another good step in the right direction
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] nmlssit:
I simply enabled MagiskHide and it passed, but thanks!

Other than that, I noticed a little bit of lag in animations, especially switching pages In the launcher, could be max 675 MHz in GPU, I guess it's the price to pay for better battery results?
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
I can't really tell any difference but then I do have the animation scale set to .5 for all three options in the developer settings.

That makes a huge difference here in terms of speed.

And I would really hope we can get PA fully stable. Once all the issues are 100% gone, we can always make it faster again ;)
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] maxcaulfied:
Hi sir, its me Matt. I have a few questions. Are you in PA team yet? Will you support ours device longterm? And will you push some commit to device tree as Akash did before? And support more hardware decoder?
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Yes, I'm in the PA team as of this week and maintaining the device. I would hope to do this into Android R.

As you may know we had several issues with the previous versions of Quartz on the Mi9 that are now fixed for the upcoming Quartz 5.

The remaining short term task is to make sure it is stable and to try and root out the reboot/freezes completely for Quartz 5.

After that it's time for Android R on the Mi9 which is coming up in the next couple of weeks and that will require updated device and vendor repos for the Mi9.

I'm pretty sure that I would try to set those up from scratch and not reuse much of anything from the current trees.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] toscha42:
Had a bad morning after first night with the latest build. :)

Woke up by myself since device didn't ring but was frozen instead, cold as normal not heated up. Had to cold start since it didn't react to any action. Never had such issue before.

[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Sad to say that I had the exact same issue this morning. Even had the phone on the charger over night and it was turned off, just like yours, when I woke up.

So I just removed the download for this quantic test version.

I'll try building another version with a different kernel branch later today. Apparently the dev changed the recommended branch last night, after I built from the then recommended (QK-inline) branch.

Until that is tested (I'll run it on my own for a day or two first), everyone is probably better off flashing back to the version from the 21st.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] toscha42:
I just can flash 20200821 over 20200827? Quantic kernel will be overwritten then?

Cheers

Toscha
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Yes, you can. Just did exactly that. The first boot will take a bit longer than usual.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] maxcaulfied:
New build are coming today? I'm about to flash the QK inline ver. Should i wait?
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Don't flash yesterdays Quantic test release, I removed it from the download directory due to the black screen of death.

I'll keep you updated once there is something new ready for testing.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
There's a new test build in the mega folder at https://mega.nz/folder/75IHSCZb#gYkiCuQaV4grDAaBpSbqyg, for those inclined to do some more testing, the filename is pa-quartz-5-cepheus-20200828-dev-quantic-n.zip.

Basically this build is identical to the dev build from the 21st but includes the very latest version of the Quantic kernel.

Due to a technical issue there is a warning after booting that you can safely ignore.

A big shout out to the Quantic kernel dev who was super helpful in making sure we get the proper branch and commits for this!!
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] maxcaulfied:
So, did you talk to Carlos? He is a nice guy tbh
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Yes I did and he is super helpful!!

He basically retired the QK-inline kernel that was used in yesterday's version, one of the reasons being the freeze issue we had.

His new kernel was built more or less from scratch over the past weeks.

Apparently the reboots and freezes are somewhat widespread for the Mi9, with other ROM's too, and he is attempting to address that with this new kernel.

Running the new build now and keeping my fingers crossed that it proves to be stable.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] maodevil:
The last maintener fixed the rebooting problem in PE and 404 rom you should ask him how he did it
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Yeah, I did ask a while back. In this thread and on telegram by PM. I think he's really busy.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] toscha42:

if it had some more customization like Pe +, I would also be very curious to try it, but I think this will never be possible
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] toscha42:
For many others it's one of the big advantages that Paranoid Android focuses on stability and performance close to standard Android instead overloading a ROM with tons of useless customisation gimmicks. There are enough ROMs out there where the developers put a different emphasis.

Cheers

Toscha
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] baggino:
it depends on the point of view, for me the best rom ever is Pe +, if you don't go by miui 12
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] toscha42:
Fair enough. So then why should PAQ copy PE+ when it's already there? There are people interested in customisation and there are people not interested in it. Both groups deserve a suiting ROM and both groups currently are perfectly supplied with respective ROMs.

Cheers

Toscha
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
I used PE+ for a while in July because PA wasn't being maintained after Quartz 3 came out.

It is a really good ROM.

The core difference between PE and PA is that PE is AOSP and PA is CAF. And I'm not sure how others feel about it, but to me CAF makes a huge difference in performance.

PA is so much faster for me than all the other ROM's out there.

Awesome, same here, hasn't disappointed yet :)

---------- Post added at 12:07 PM ---------- Previous post was at 12:04 PM ----------

I'm all for customization too. Crdroid has awesome features, I love the battery charge limiter and many other aspects of it. It's a great ROM with a super dedicated maintainer.

So much stuff to tune, great fun.

Derpfest is similar, great features and a really knowledgeable dev behind it.

Love both of them and would recommend them both for someone looking into the direction of customizable ROM's with many features.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] mucha17:
Hello, I'm looking for a ROM to switch from MIUI. I have a few questions, because I want to use MicroG instead of Gapps.

1. Does this ROM support signature spoofing?

2. Does this ROM come with Gapps included in the zip? If yes, Is it possible to somehow remove the Gapps from the zip, so the Google services are not installed? Would a ROM update override MicroG with Gapps?

3. Is WiFi Calling working?

If someone could provide me with this information, I would greatly appreciate it.

Pls some tell me, is wifi problem fixed or not (Connect/Disconnect)?

Thank you
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] toscha42:
As said before every fool is different. :) I'm not interested in customisation at all, I consider that as unnecessary bloatware. And as long as there are ROMs developed avoiding customisation I'm fine with it. One untinkered ROM, as close to pure Android as any possible, is enough for me. For the time being that's PAQ. LOS would be quite similar but doesn't receive respective support currently.

---------- Post added at 03:08 PM ---------- Previous post was at 03:06 PM ----------

I don't know. I'm not the developer just a happy user.

Which WiFi problem? Never experienced any issue with WiFi on PAQ.

Cheers

Toscha
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
This ROM does come with gapps. It also provides signature spoofing and vowifi is working.

If you plan on using microG you are probably better off with another ROM.

Having said that, google voice activation works too even when the screen is off :)

---------- Post added at 02:29 PM ---------- Previous post was at 02:26 PM ----------

There shouldn't be any issues right now with wifi. Actually for the last developers versions I added a commit for some wifi config changes that may make a difference. From what I saw they prioritize 5ghz and have some other minor tweaks. Best is just to try it. Here all wifi networks are working without disconnects.

---------- Post added at 02:35 PM ---------- Previous post was at 02:29 PM ----------

Well we all hope so. Builds are done centrally and there will have to be testing too. If I should take a guess it could be around mid September with the September patches.

But that's just a guess. Might as well come sooner.

Anyway it's not so much of an issue for our device since we can use the dev versions. For those still stuck on Quartz 4 the waiting may be more painful.

Thanks for continue developing this great Rom! You're doing a fantastic job!
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Thank you but to be honest I'm not doing all that much, just trying to do the little things to restore what is not working and to make the ROM more stable.

We're going to get the Android R sources next month and it would be great to have a stable Android 10 PA before we all move on to the next one :)
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] spetrum:
I am disappointed, there is no way, after the flash and reboot the system that restarting in looping, does not boot.

I thought it was the firmware, I was using Firmwire V12.0.1.0 QFAMIXM, so according to the instructions of the OP, I flashed the V11.0.8.0 QFAEUXM firmware but it didn't work, same symptom.

Has anyone experienced this problem? I did exactly these instructions bellow.

- Reboot to TWRP (Mauronofrio 76)

- Format data

- Reboot back to recovery

- Flash PA zip

- Reboot
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] toscha42:
Just in case you've never installed an AOSP ROM before on your device you need to flash vbmeta.img. Instructions can be found in the LineageOS thread.

Is it normal after flashing the latest test zip that after reboot the phone says 'theres an internal error'?
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] toscha42:
Yes. Don't know why but seems to be an issue for many current AOSP ROMs.

[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Also make sure you are actually formatting (the advanced option that requires you to say "yes") and not just wiping data

---------- Post added at 06:02 PM ---------- Previous post was at 06:00 PM ----------

It's a mismatch between the kernel and a vendor setting/config. This is a known issue and will be fixed in case we should merge the kernel into official Quartz.

You can safely ignore it for now, it has no impact on the device
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] spetrum:
Now it worked! Thank you!
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Yes, definitely very good advice.

You only need to do this once and then no more as long as you stay on non Miui ROM's

You are even quick to respond! =)

Thanks, I'll keep trying this one for now. The other build locked up on me today so hopefully this will keep it from happening. Quite in love with this version of Android after running MIUI for 2+ yrs. I forgot how nice stock-ish Android was.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
The other build being the one from the 21st? How did it lock up on you, did the screen go black and unresponsive? If so, did the device stay cold or was it hot?

Reporting a bug: Clicking Home Settings from the phone background keeps crashing the systemUI. It's been there for quite a while, I guess it's known?
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Teadious:
Had phone in my pocket and went out to another place, when I got my phone out to check it the screen didn't turn on. It didn't feel too hot (I do have a thick case on it though so take that as you will) and it definitely wasn't off since the notification led was blinking. Also yup 21st build

Was it by any chance a live wallpaper?

Always change my wallpapers like that with no ussiws. Last week I tested the new pixel 4a battery live wallpaper and had the same thing.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] nmlssit:
Nope, just a normal wallpaper. But I guess I'm mistaken, it just take to press and hold from the launcher to replicate the bug.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Strange, I change the wallpaper quite often and never had that. Maybe post it in the telegram group to see who else has this?

---------- Post added at 08:23 PM ---------- Previous post was at 08:20 PM ----------

Do you by any chance know whether you had location services on? Usually these freezes stop completely when location services is turned off.

And I really hope this new kernel fixes what is left of these issues for good, I guess in a few days we'll know.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] nmlssit:
Done, apparently just one. I tagged you in the recording too
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Tested with that wallpaper and it works well here. Strange. But as you probably saw, someone else has the same on another device so it's not device specific.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Teadious:
Yeah, I always have location stuff on. Any idea how to reproduce so I can test if it still happens or is it randomly? Else we'll find out soon enough wether it's fixed or not. I'll survive either way, had the dreaded sleep of death on nexus 4 I think it was. so I'm kinda used to it

Just had a crash/reboot while listening to Spotify over headphones, turned off location now to see if that stops it, phone did feel kinda hot when it rebooted
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
The DEV builds are signed with different keys than the official versions so it's possible the spoofing is not working as expected. Using magisk and magisk hide will fix that.

---------- Post added at 11:15 AM ---------- Previous post was at 11:04 AM ----------

The typical crashes we had been seeing recently were black screen freezes with the phone still running and getting hot in the process. You just couldn't unlock it anymore.

The issue you know had sounds like a spontaneous reboot (possibly even a system UI reboot) so it might be unrelated. It would be very interesting to see if it happens again with location services turned off.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Assuming you haven't flashed another ROM, could you do me a favor and check to see if you have any files in the /sys/fs/pstore directory?

Something like /sys/fs/pstore/console-ramoops

That would be the log from your last reboot.

In case you have that log, could you send it to me?

Either here or on telegram (https://t.me/Cave_Diver)
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] vortitu:
I'm on the build from 21. And I have a problem with fingerprint unlock.

I use 1password and set up biometric unlock via fingerprint. If start the 1password app, fingerprint unlock works perfectly.

But if I use autofill feature in another app, I can't unlock 1password with fingerprint. I get the dialog to use the fingerprint, but it seems my finger isn't recognized.

I tried to delete my fingerprint, reinstall 1password, but that doesn't work.

Anyone has an idea why this happens?
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
I use Enpass as a password manager and I've had that happen in the past. Basically Enpass would show the fingerprint icon but no matter what, it wouldn't unlock.

Don't remember what version I had that with but I'm pretty sure it went away after rebooting.

Also when upgrading it can't hurt to delete the cache and dalvik cache. Maybe try that and then test again. Also try another app that uses fingerprints to see if it's related to 1password.

You could test with the Ebay app for example or Enpass.

---------- Post added at 08:14 PM ---------- Previous post was at 08:08 PM ----------

As soon as the kernel warning issue is solved, I'll build another DEV version and will make that a different build type that should pass safetynet.

By the way, I was out in the car and in a lot of different places over the weekend, with location services on and had zero issues. The last time I had the classic freeze/reboot was a long time ago.

So I'm beginning to think the last reported reboots maybe have a completely different cause.

To those of you who had this, are there any specific Magisk modules you are using?
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] vortitu:
Fingerprint works in all apps without Problem.

Even 1password unlocks every time with fingerprint, if I start the app.

The only Problem is in the autofill situation.

e.g. I open a web page and have to enter credentials, then I have popup "fill with 1password" when I tap this, the fingerprint-input-dialog overlays the browser window to unlock 1password and fill in the credentials. And I this situation the fingerprint unlock doesn't work. And only in this scenario.

Attached screenshots shows, what I mean.

Edit: Sorry for the german language in the screenshots, but I hope you get the point
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Cave_diver:
Maybe give that a try with enpass. Not sure it is still free to test, probably is. I use autofill a lot with h enpass and it works with the fingerprint. Also maybe ask in the PA tg group to see if someone else has this issue on another device with 1password.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] vortitu:
Tried it with enpass, same problem, app unlock without problem, autofill uock doesn't work.

I will ask in PA Group if this is a known issue.
