[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
Decided to try myself some RR on the Poco X3 after using it for a while in my Redmi Note 8.

Coming from Xiaomi.eu v12.0.9.0 and after upgrading to the latest TWRP ('twrp-3.5.2_10-5-surya.img', as I was still on brigudav's v3.5.2_10-3) I downloaded everything to an external SD card and prepared to flash by taking a backup with Migrate-NG.

As I decided to downgrade the firmware (to 'fw_surya_miui_SURYAGlobal_V12.0.7.0.QJGMIXM...'), that's the first thing I flashed after which I rebooted into recovery just for safety.

Then I flashed the ROM ('RROS-Q-8.6.9-20210609-surya-Official.zip') and the DFE ('Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip') before formatting data (by confirming with "yes") and rebooting yet again to recovery.

Lastly, I flashed GApps ('open_gapps-arm64-10.0-pico-20210701.zip') because I need to pass SafetyNet (it did) and have access to the Play store.

After rebooting to system, everything looked nominal, with no bootloops or errors.

I rebooted to recovery once more to install Magisk (from TWRP's Advanced options) and flash my Migrate backup -- everything went overly smooth.

Now I'm going through testing connectivity, loging on to G services and tweaking a gazillion options, but up to this point everything appears to be working...
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] redymedan:
Watch this, I have found the problem!
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
My device was Play protect certified from the start, didn't have to do anything... 🤔

BTW, there was a typo in RR's filename above, now corrected.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Jishin Varghese Jose:
Can I use the same vendor file for non nfc variant ( KARNA)... should I do the same steps in karna to....
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] redymedan:
not tested on karna, but I think it will work
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Jishin Varghese Jose:
So can i flash the vendor file in my phone..
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] redymedan:
Yes, you can. that is global vendor
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Jishin Varghese Jose:
Thanks for your help bro...
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] berni502:
sup, so I have auto brightness turn off and adaptive colors also but in strong light conditions something is still boosting brightness and/or contrast. It is a bug or maybe I am missing some switch xD?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
I think auto brightness doesn't work anymore. Anyone else?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] berni502:
was it working before? i think something is working not matter if you turn it on or off
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
Yes it worked before. I think since the latest update it stopped to work. May be someone else can agree or disagree.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] berni502:
something is quacked outside my phone is performing some serious light show inside not so much but it is changing no matter that i have auto-brightness turn off and adaptive colors off :p
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] temporarium:
Did a quick test under a lamp and it did increase/decrease fine. I haven't noticed it being "off" in any way 🤔

Check this setting:
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
Interesting. Checked the settings and they are identical. Then tested it again and now I can see that the brightness slider in auto mode moves when light condition changes.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] temporarium:
So, is it working for you?

Like I said, with that particular minimal brightness setting (which is a fantastic idea) I haven't had any brightness issues. It's been so "out of the way" that I haven't needed to pay any attention to brightness... until you brought it up 😁
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
Indeed it works. I can see how the brightness slider moves when I play around and with my desktop lamp.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
In settings, sound there is the Mi Sound Enhancer. I'm trying to create a task with tasker to open Mi Sound Enhancer directly so I can add this task in Xposed Edge Pro. In Tasker I create the task 'Launch App'. Then I could select the desired app, or in my case the specific setting. I see tons of settings. But not Mi Sound Enhancer. May be they call it different. Does someone know whats the name of this particular setting?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] berni502:
I dig up some more information about that contrast issue and it is probably Qualcomm adaptive/assertive display turned on. It's the same for miui so i guess rr is fine but that option is still annoying.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] veloz46:
Could someone provide me with the framework-res please? I wanted to look at one thing and I don't want to have to erase everything haha.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
Does anybody know if audio quality has improved from Firmware 12.0.7 to the latest version or didn't change anything in this regard.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
I flashed V12.0.9.0.QJGMIXM with orange fox. After a reboot into OF, it still shows 12.0.7.0. Why is that? Do we really have to flash MIUI full rom to update vendor?

Checked build.prop file in vendor partition. vendor.build.security_patch=2020-11-01

So, flashing latest A10 vendor did exactly nothing.

I downloaded the vendor file from here; https://xiaomifirmwareupdater.com/archive/firmware/surya/
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
Hi

with V12.0.9.0.QJGMIXM you only updated the firmware, not the vendor. Or am I wrong?!
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
really? Now I'm not sure.. If this is firmware, where could I check if it got updated? And then remains the question how to update vendor.

I thought that file is the extracted vendor from the official MIUI rom.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
hey, that's the link for the vendor:

https://xiaomifirmwareupdater.com/vendor/surya/
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
Thank you. They are quite old. I guess the only way to get the current vendor is to flash MIUI.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
Small input bug I have noticed after using RROS v8.6.9 for over a week: when editing text fields, the context menu popup is displayed in front of the field instead of slightly above, making it useless in practice. Anyone else noticed this?

Also, bluetooth audio is showing a few crashes and a lot of interference, but I do have ViPER FX 2.7 Magisk module installed, so there's a lot of variables here.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] nelsonmenon:
hi guys, I'm on stock latest MIUI 12.5 (Android 11) and I want to flash RR.

I already start unlocking the bootloader (166 hours remaining)

What's the right way to flash RR? Is there anyway of bricking since it is downgrading from A11 to A10?

Do I need to flash 12.0.9 firmware before flashing RR?

Is there anyway to bypass the waiting for unlocking bootloader?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] temporarium:
Wait it out. Then flash via Mi Flash tool the latest MIUI 10 https://xiaomifirmwareupdater.com/miui/surya/stable/V12.0.9.0.QJGMIXM/

Be careful not to relock your bootloader when doing so.

Then follow instructions in OP to flash recovery and latest RR.

Note: you'll have to format your data, including internal storage.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] nelsonmenon:
Thank you Very much
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
No issue here with Bluetooth. But I don't have viper installed.

Can you use latest magisk version with viper?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
I'm using v23, actually. But I might not have followed the standard procedure... (I have no precise recollection, I may have used the rootless driver module instead).
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Danmann:
Is the dev still with us? Or any other news?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] ocujos:
The latest RR build for other phones is at 8.7.1 so, probably not 😔
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Danmann:
Hm..

At least he's still alive. His GitHub acc is still active.

@Lostark13

Can you give us some news?

Thanks
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Lostark13:
I Will Definately Update The Rom When There's A Major Update In Source Side
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] m0han:
not meaning to push you, but will that be android 11?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Lostark13:
I Have No Idea If It Will Be A10 Or A11.

But Will Push Any If There's Any Of A10 Or A11
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] temporarium:
Please keep supporting A10. Personally, I prefer a stable older ROM with full control over one with G's API restrictions, etc.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
Mee too. ✌️
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
Me too. I prefer stability.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
Guys, sooner or later it will be on A11 anyway! So why not face the future and warrant a (possible) jump to 11 ?!
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] temporarium:
Only when there are workarounds to all those restrictions/limitations, like via Magisk, etc.

I'd rather secure my device personally, rather than entrust my "security and privacy" to G.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
Okay, it's up to the devs to decide if or when to continue. But in the end Android is Google and I hope that the RR devs are wise enought not to bring every google crap into the Rom.

By the way: Thanks for the further development!
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Danmann:
At least security updates every month would be great.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
To that, I answer: why let go of a sure thing for some unknown benefit?

Personally, I'd be satisfied even if it was every quarter...
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
Cleverly said :-), but an unknown benefit is also a benefit!
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
Just out of curiosity; are there other custom roms which have something similar to 'slim recent' like RR got? The way it is in MIUI is also fine.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] m0han:
afaik: aicp and baikal os, which is based (loosely?) on aicp. maybe havoc os too?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
Thank you. At some point I might try another rom. Havoc doesn't have it. At least not on official Havoc (A10) for the Redmi Note 9 Pro Global (which is BTW a great device too).
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
I'm experiencing massive battery drain with very light use and from apps that never before gave me problems -- like F-Droid Classic, which I was advised to restrict form running in the background, and ClipStack, consuming 15% charge.

Also, the device feels warm to touch almost all the time. Anyone seeing this on RROS?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
I had this issue a few days ago. But I didn't see which app caused it. And I have not installed F-Droid. Restart phone didn't help. Charging at this time was very slow. It took about 10 Minutes for 1-2%. Then I shut down the phone overnight and all was fine again the next morning. Weird.

There is another thing I experienced 2 times now (normally I won't let drain the battery that low). Battery gets below 7%, 5% or so. Audio stops working, phone comepletly muted. Restart phone, audio is back. But now edxposed doesn't work even though it's activated and the modules too. Xposed Edge Pro says, module not activated, but actually it was. After another restart it's all fine again. I don't have any power savings settings activated. Although it looks likes the phone goes in an aggressive power saving mode. The first time this happened phone took a long time to restart. Now I'm pretty sure this is reproducible. Any suggestions?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] temporarium:
I'm not exclusions any of these, but the suspicion would fall in the kernel.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
I am using the ROM's default -- any kernel replacement suggestion?

BTW, the situation improved in the last day or so, after a full recharge. I suspect some kind of low level race condition triggers this behavior.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
Me too. Using ROMs default kernel.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
I haven't had any problems with the official kernel so far. maybe the OS should be updated, what do you think of that, pnin? ;)
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
Apart from what I reported, mostly everything else is running fine, apparently.

I'm partial to StormBreaker kernels, having used it with good results in the past, but I have zero experience with it on RROS -- in fact, I don't even know if it's supported...
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
I heard that the RR doesn't accept any other kernel because it's not an OSS version. Don't know if right or wrong
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] jlovelo:
I have successfully loaded F1xy kernels with this ROM, and which resolved a minor problem earlier on, though it looks now as though the dev has closed off on that one. I'm back to the Cannon-v2 which is default with RR.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
so is it possible to install other kernels ?! thx for the news
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] jlovelo:
I only have one experience flashing an alternative kernel which worked fine. Search this thread for "kernel" to see some references. Try at your own risk.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Sahem1992:
Thank you for this GREET ROM

I wish in the next update to add camera like MI camera which have a lot of feature specially **64mb** support

And it will be so good if there is a different choice for charging animation while the screen is off **now there is only pixel charging animation**
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Jangoux:
As far as performance how does this rom compares to arrow? I remember back in the Kenzo data RR was notably heavier than its counterparts due to the extra features it has but how does the current one for Surya compares?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
Hi guys, any news about September security patches for RR?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Danmann:
I think this Rom is dead. But lineageos is official 👍
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] temporarium:
For me, it's not about official or not, but having full control. My phone works perfectly with a solid Android version.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
:unsure:
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Danmann:
Well, more eyes look over the source code. That's a good thing by official. Main problem is here the security updates.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] temporarium:
Very true about the source code. You don't install just anything, of course.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
Damn Right!!!
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
Hello, I just wanted to write again in this thread, because I'm still hoping that the development of this Rom goes on. Unfortunately, I do not use them, since I'm now unattended to Android 11.

Unfortunately, I have not found a Rom so far, which, on the one hand, permits the highest(!) level of changes to a Rom and on the other hand almost completely renounced on Google-crap (all "Vanilla" Rom I have tested have either Google Cam or Gallery, etc.)

I know DEVs also have an RL and will not be paid for their valuable work.

That's why I just wanted to express this desire that the development of this Rome continues. Amen and thank you for 2 minutes of your attention!

Greetings

H0rdak

P.S: If a further work is in progress - what I do not know, see that as a thanksgiving for your great work !!!
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] temporarium:
I'm still on this. Reading all those A11 and A12 threads, I'm glad I stayed 😁.

Would be nice to have someone merge in the security updates every few months. But with Adaway & Adguard + common sense, haven't had to worry 'bout security much - not as much as I would on untested quickly-pushed-out ROMs.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
Android 11 is not bad in itself. ;-)
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] siljaer:
I agree. It is an excellent ROM. It allowed me to go without gapps and magisk/root, yet with two important features to me: auto call recording and battery charge limit, already in the ROM out of the box.

I upgraded to LineageOS only a few days ago, because I lost any hope of a new version of RR. LineageOS is an excellent ROM, but it has not those two features above, so you have to live without them unless you root the phone.

I realize that we belong to a minority: people that just want a degoogled phone and with a reasonable level of security.

I am not against Magisk: it is a valuable tool for many tinkerers wanting to use their rom of choice with google apps and/or some closed source app they need or to tailor their phone to some specific need. But I belong to the minority above, that's why this ROM was perfect for me.

As for other roms adding some closed source camera, I have to say that this rom worked not very well with open source cameras. I understand that most of the people just want to use that. I have not tried google cam, but my experience is terrible with any open source cam, with RR or lineage, so probably proprietary software for cameras is the only way to go. I realize that rom and open camera developers cannot do a lot, since cameras rely more and more (heavily) on proprietary software.

I could write much more about those problems but I would go off topic.

I am joining you in thanking the developers for this excellent rom that granted me many months of trouble free life with my phone :)
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
Amen to that -- although I still use its Play Store...
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] rn3miii:
Can we please get security updates on this rom?

Or alternatively, what's the closest similar ROM that gets actively maintained?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
Maybe arrowOS 11/12 - Not quite as many change modes as RR but timely updates!
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] m0han:

have somone the problem, that after lock the display, the touch not work?

i must hardreboot (push 10 sec the power button) all time the device to use it.

First I had this problem a few months ago when I charge the device, but now it is no longer usable :(

i found only one other guy with an X3 but on different ROM (evolution in his case)

i run current on RR v8.6.7, i will try to update on the newest version.

i found people talk about firmware updater installationfor the phone must be done before flashing RR rom

can anyone explain if should i use this method "note that i cant find the surya_fw_vendor_V12.0.8.0.QJGMIXM_08f5c8_10.0.zip"?

Yes, flash latest Android 10 MIUI using Xiaomi tool (careful not to relock bootloader), install TWRP, FORMAT data, and install ROM.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] insanebarneykid:
thanks for replying any hint on how to do this

What precisely have you done?

What firmware are you on? You need to be on A10.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] saiff663:
I'm on latest firmware, 12.5.4 on A12

Hello,

I still have resurrection remix version 867. It works quite fine, but I would like to update.

Is there a follow-up for this RR version 8.6.7? Where can I find it?

Thanks in advance for your reply

[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] temporarium:
8.6.9 is the latest: https://sourceforge.net/projects/resurrectionremix-ten/files/surya/
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
I think about to move to A11. I guess A12 is not stable enough as of now. Installed A12 Evolution X on my Mi A1. The phone crashes sometimes.

Coming from RR, which custom rom based on A11 is stable and has similar settings. For instance I appreciate to control volume per app. Also th Mi Sound Enhancer is nice.

Any suggestions? I would wait for RR but it seems RR project for surya has died.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] H0rdak:
There is (unfortunately) not that much choice anymore. Havoc OS still has quite a lot of customization options. it is also well mentained.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] temporarium:
I would make sure the A11 ROM you choose will continue to receive updates. Otherwise, what's the point of moving to an "older" ROM. A13 is already coming out...
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] XtraWater:
That's difficult or impossible. See RR. Used RR since MI A1. In this regard I wonder what it means when a rom is 'official'.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] temporarium:
Official means the team behind the ROM (for all devices) approved a maintainer for our device. So, if this maintainer moves on to another device, it's a little bit more likely someone else may be able to carry on - no guarantees either way.

Anyway, this A12 is looking promising:
