Guys, any idea why Fortnite doesn't work with this custom rom? I had to flash PE 10 in order to keep playing it. I wasn't using Magisk at all, in fact I did several clean installs of the rom, thinking I messed up at some point. Anyway, the game is running fine in PE 10, but I miss all the Evolution X features.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] jackuars:
What is the correct/preferred order of flashing for these items for fresh clean install of any ROM. Please mention if device restart or restart to recovery is required in middle.

GApps, Firmware, Magisk, Kernel, ROM, DFE, Wipe data, Format data, Factory reset, Advanced wipe (dalvik, cache, system, data, internal storage)
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] ninad7478:
Wipe everything except SD Card and USB. Flash ROM, DFE and reboot. (Gapps included, firmware included in latest zip.) Set your phone up, use for some moments, reboot to recovery, then flash Magisk and reboot to system again.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] troyinjapan:
GAPPS and Firmware are now included in the ROM.

Do this for a clean flash:

Back-up Internal Phone drive to Hard Drive!

1. TWRP > Wipe > Advanced Wipe >

a. Dalvik/ART Cache

b. Cache

c. System

d. Data

Swipe to Wipe!

2. TWRP > Install > Flash ROM

3. TWRP > Install > DisableForceEncryption

4. TWRP > Wipe > Format Data > type "yes" and blue checkmark

NOTE: This is going to erase the phone's internal storage!!!!!!!!!

5. Reboot System

6. TWRP > Install > Magisk (if needed)

Switched to Havoc OS for time being, until a new update is released. The frame rate is pretty bad for pubG in the latest version, with constant lags. Jan 26 update was perfect, but somehow the Feb 8 version messed things up. Will switch back after a new update.

Thank you for an amazing guide. So I was asking for ROMS in general. Where does flashing Firmware, GApps, Factory reset & Kernel come in this guide. Can you please for my sake, add these in your guide here.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] troyinjapan:
This is an Evolution-X thread, not a thread in general for other ROMs.

You should really do some research, especially on YouTube.

Spoonfed information here:

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] jackuars:
If I want to flash NoGravity kernel and Magisk after install, in what order should i do this?

Thanks, I'm fairly knowledgeable, I just wanted understand, since not all ROMS have all these detailed steps
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] troyinjapan:
The first post of every development thread on XDA projects has instructions on what to do, including this ROM and every other ROM, and every kernel. The first post on NoGravity kernel also has detailed instructions.

Challenge:

Read. Post what you think the detailed steps are. then people will comment. Asking people to detail out every step because you're new or not willing to research a little is lazy. Then when they do, you even fail the common courtesy of pushing the thumbs up thanks button. Challenge accepted? If this isn't Evolution-X specific anymore, move to the general section.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] jackuars:
In most of the forums I've been in, the easiest way to pick things up is through Q&A. Letting newbies read through hordes of text is not the right way to do so. I have done my initial research, but then the instructions aren't the same everywhere. Yes, I understand no one is obligated to answer for the Q&A, and hence these are the open forums. I've been an Android dev myself back in 2011, when the O.S was young and vibrant, but have ventured into a new career. I'm a little bit rusty at the moment. And you'd have to consider the age difference of people who are browsing the forums.

Thanks for the helpful replies you've given, yes I guess I've never used the thumbs up or thank you button because I didn't see it, not really a socially active person, but now I've did that part.

One question, why is the firmware version 11.0.4 when the latest one is 11.0.5?

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] shukrant tanwar:
Review after 48 hours

ROM is very smooth to use, all the transitions and animations are good. Battery life is also pretty good, getting around 6 hours of SOT with full-on multimedia usage (I do not olay PUBg though).

Gcam is also working, I recommend you install gcam as the in built camera app is very bad.

Only problem I'm facing is with mobile network, I sometimes feel the network isn't connecting to the internet as it was doing in the stock ROM. Calling and messaging is perfectly fine but internet is somewhat glitchy, hoping this would get fixed in the next update, I recommend this ROM. Loving it so far.

11.0.5 is the latest for Android 9.

Yes that's correct. MIUI went backwards a version for their Android 10 release because they can't count.

Yeah, i think it's something to do with the speakers or something similar. I can't get them to play any media noise. If i have earphones or Bluetooth speaker connected (or any external sound source) no lag or stuttering at all. But if you try to play media with sound without an external device then it's a mess. Only happened in the most recent update for some reason.

Everything is working fine except the data connectivity.

So i have to reboot the phone everytime to get the data active. Please suggests any solution. I am on the the 11.0.4 firmware with three ROM and nothing else like kernel or magisk. Prior to Evo X i was on EU ROM and did a clean flash with interal storage also as mentioned in the steps as to remove encryption. Please someone suggest any solution.

I'm running the Feb 8 build, and I'm encountering some issues:

1) screenshot shutter sound toggle doesn't seem to work. The sound comes no matter what I do.

2) I can't find ambient display settings anywhere (stuff like wake display when phone is moved from pocket)

3) have some customisation options been removed? I can't find any lockscreen styles now.

4) option for fingerprint unlock after reboot also seems to be gone

I've clean flashed twice, to the same results. Can someone help?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] preducer:
Yup the option is missing from 8th Build. U need to rollback to 2nd Build or what u can do is flash 2nd then dirty flash 8th, although the options will be missing but it's still works provided u have turn it on 2nd build

only annoying "BUG" i found in evoloution x is... its soo, unoptimized.

poco f1 has the RAW power of a 100$ phone, according to geekbench scores of evolution.

i noticed it too, in 2 scenarios.

-- 1. when you are scrolling something long... it starts to hang and get weird glitches as more and more content loads into the memory.

2. there is a stupid game "castle wreck", and it can clearly show what i mean.

the more stages you clear... the more game starts to lag... to the point its literally unplayable... like using a galaxy s3 in 2020. that slow.

and as soon as you close the game and restart it... it works fine.

so there is some problem with the memory management i guess. if this is solved... it and AWESOME pixel !
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Elizeu7771:
of all the ROMs I have tested, this is undoubtedly one of the best and most complete I have ever seen. The battery savings are incredible, and also very fluid, although the fonts still don't apply completely in the apps, example: the font doesn't apply in WhatsApp conversations, but the ROM set is incredible, congratulations to the developer. I am still using Miui EU (Android 10) because it is more complete, and for doing encryption it is working perfectly, and also the battery savings are amazing using Magisk modules.

Sorry to bother with such odd question but im having really hard time with getting San1ty GCAm mod (or any other gcam mod) to work with this cool ROM.

Any help will be greatly appreciated
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] mragentofchaos:
It is possible there may be an issue with gcam after updating to android 10 firmware. As some users have pointed out earlier, using No Gravity Kernel's CamFix version helps. I went straight ahead and flashed it before even booting the ROM, so I wouldn't really know what would have happened with Gcam had I not done that. If you're not using the NGK CamFix, maybe try that. On my device, san1ty's F1 Minimal Mod works flawlessly.

finally someone mention it... apparently it has something to do with the kernel optimization. When i use FKM and change the cpu governor to performance and use the highest setting. The micro stuttering become less apparent and its kinda smooth again when scrolling Twitter/Play store or any social apps. At the moment, i just use Twtiter Lite because i dont want to change the kernel setting. Tho i mention play store and other social apps, only Twitter showed the biggest problem about the laggy.
