Can someone explain "3. Flash the pie fw" part?

Flash Pie firmware (9.5.16, 9.5.23 etc.).

It's okay to just flash it over 8.12.20? It just doesn't feel right to flash ~60 MB Pie update when my latest fw was Oreo.
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] Shefczenko:
It's not a whole pie system but just a baseband, a BIOS update you can say. just flash it and you're good.

Several insights and conclusions after 19.07 build.

I use this rom since very beginning of it however through this time I see mostly more bugs, as well as bigger and bigger ignorance growing with every build.

Screen off torch doesn't work since couple of releases.

Screencast never worked properly.

More or less in March phone started rebooting randomly, especially while calling with lte enabled.

Smart charging never worked.

Device section in havoc settings was removed instead of repair.

Contact with maintainter is none, except uncommon answers about clean flash.

I don't remember how long ago I have seen device last changelog.

I can count more such... phenomena.

This rom was great and it promised very well but sadly I have to say that it became a sneak peek for people looking for novelties instead of functionality and stability.

Last not quite but almost stable build was 15.04, and I'm tired after another unknown update with

no changelog,

with same bugs,

without noticable changes,

another soft reset.
[MENTION=5301398]lightvortex[/MENTION] please, let people know if you have no time or mood to maintain this rom.

Otherwise do something.

I tried this Havoc ROM and Lineage 16 followed the instructions. Although both ROMs have cleaner system and are supposed to be faster than MIUI, I can tell it is actually not as swift as stock ROM (stable 10.3.5, Oreo). I used Geekbench Pro to test the performance immediately after reboot, the scores are: Havoc, single-core 1723, multi-core 5724; Lineage: Single 1625, multi 5520; MIUI: single 1910, multi 6691. I just went back to stock.

I have had custom roms since the HTC HD 2. And gone through every possible custom ROM flavour in my countless phones since. This "was" the best rom I have ever used in terms of customisation. Now it's the most neglected. I do appreciate "ALL" the effort that has gone in so far but I agree with the above posts, off late, I am disheartened by this ROM. [MENTION=5301398]lightvortex[/MENTION] Was the it something someone said here that hurt you and demotivated you? If it is not and you just don't have time, I am willing to learn how to make a ROM and maintain it, if you would point me to the right resources I would gladly continue this legacy.
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] lightvortex:
I haven't been able to make much changes in the ROM cause I'm trying to build with System as root trees like posp ,nos , unofficially lineage ,etc updates should be fine by next week :)

Updates might come out a bit late for everyone cause I wait 24hrs for testing before release
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] jonny.will:
Thank you for replying so soon, is there anyway I can help? Or we as a community may do so?
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] lightvortex:
thx for the list of bugs I'll fix it asap I didn't know about charging and Mira cast (last time(about a week ago) I checked it was working fine).

about changelogs it's just havoc upstream I haven't made changes in device trees other than kernel security upstreams cause I'm trying to fix sar trees (proximity broken)

I'll add device sections back in next update

My phone started to reboot randomly, 5min ago I was just scrolling through XDA and it rebooted, previously it was rebooting because some live wallpaper, also strange.

Live wallpaper was Fluid Sim Free, it was running on 60fps but again, cmon, this phone is the beast, it shouldn't restart because of some wallpaper.
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] lightvortex:
Give logs,I'm also using live wallpaper ( pixel 3 live wallpaper) so far no reboots
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] EZY-E:

Now it restarts when using tinder.

Should I try another rom?
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] A18415:
There are no issues at all from my side. Working absolutely fine with no random reboots as complained by you. Just follow the right procedure of flashing this rom. If you can't work it out just ask lightvortex or someone from the team of havoc. Pretty sure you're doing something wrong.
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] EZY-E:
But at the beginning it was good, maybe I installed something in the meantime, I will try to disable/uninstall thing by thing.

Hi while installing havoc is I'm getting update process error in twrp
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] dark_prince:
I think I flashed over 8.12.27 beta and never bothered to downgrade firmware. It works.

Battery life is great, especially on standby.

Sometimes battery percentage gets stuck or the charging doesn't start with rapid charging, a simple unplug-plug solves the issue.

While gaming, rapid charging doesn't trigger and slow charging current isn't sufficient to charge the phone up.

For the light apps its as good as MIUI's backup. Battery drops faster when gaming tbh.

Any tips on how to stop random reboots?
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] mgarrison3389:
I was getting reboots. Formatted, flashed fw, flashed rom and gapps. All was good
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] EZY-E:
Ok, I tried: wiping everything (except internal), flashing pie fw, rom, gapps (this time micro), restoring apps, I even changed my SIM card for new one (someone said they fixed same problem with new one), uninstalled magisk and every module, tried updating webview (someone said that is the problem) - again, same problem.

Now, to go more deep in what is happening, every time I open: chrome, tinder, okcupid and scroll a bit on these apps after some time pictures stops to load and mobile icon in status bar goes hollow (not full like usual) and that is the sign of reboot to come.

Also some heavy apps/games cause phone to reboot like Antutu Benchmark and some zombie game with high graphic.

Maybe it restarts because overheating?

What is common for all this apps is they use internet and if I understood it right - webkit or webview, they connect to internet using something like that.

But I tried updating webview and changing from android webview to chrome webview in developer settings but reboot is still there.

I managed to capture (I think) log of what is happening before reboot so If anyone is willing to inspect I would be really thankful.

I tried to see where is the problem but I don't have enough knowledge to see the problem.

I'm on Verizon, and whenever I have incoming calls, or missed calls, they appear in the dialer as my name. Whenever I tap into the call, I see the phone number as +1MissedCallNumber+1MyPhoneNumber. If the incoming phone number is 555-666-7777 and my phone number is 123-456-7890, my dialer shows +15556667777+11234567890 as the missed/incoming call.

I got to say in all honesty having used this rom for almost a year, its very poorly done. I know I'm being that guy complaining about free stuff on the internet. But this rom has had continuous problems that have never been addressed. Each new update adds more broken features, and each new update runs equally as bad. I've really lost hope of the light sensor ever being fixed and for the kernel sleep bug, let me tell you. Nothing is more infuriating than having to continually reboot your phone because the screen wont respond. And worse yet, ever since switching to this rom ive been unable to flash an actual working rom. So user beware, this is very far from a finished functioning rom. And that seems to be the case for all versions of it.
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] lightvortex:
What's wrong with the light sensor? When was the last time you did a clean flash? If you are facing issues on all the roms then I suggest you flash miui pie from fastboot then try flashing a custom ROM
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] cccchug:
Even official MIUI has got problems all the time. Also about the issues you mentioned I haven't met one yet. If the problems continue, just flash back to MIUI or get your phone checked and see if there are some hardware issues. And just like you said this is some "free stuff" so lower your expectations and be gratitude. And to be fair, this is so far the best custom rom I've tried for mi mix 2.
[Xiaomi Mi Mix 2 ROMs, Kernels, Recoveries, & Other] ysop:
Last weekend I flashed havos, AICP, aex, rr again from miui10. When I use WeChat to voice call or video call anyone, he/she can't hear my voice, and in video call I can't hear his/her voice. (WeChat say recording voice fail, seem something using microphone, I reboot my phone but still don't work)

And I can't hear wechat voice message by earphones, but speaker and bluetooth earphones works.

The issue also in AICP 8/26 build, but aex and rr latest build all works well.

And I remember the issue don't exist in havos and AICP early pie build.

Edit:

Thank cccchug, I find AICP 9/2 build fixed the issue. Perhaps this information can help a little.
