[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] riccardosimo:
I tried to do what you both guys said but every time I reboot the phone it brings me back to recovery :( that's what I tried:

1) Went to TWRP (I installed this TWRP

TWRP-RedmiNote9-V12.0.6.0.QJOMIXM-20201213-wzsx15-sanja56)

2) Wiped everything (Dalvik\Data\Internal Storage\Cache) and then rebooted the recovery

3) I insert an SD card in which I put the vendor file you linked and then the last PixelPlus UI ROM

4) Selected first vendor-firmware.zip and added the second ROM.zip then swiped to flash

5) Once the installations finished I went back to the main menu of the TWRP and Wiped everything (Dalvik\Data\Internal Storage\Cache) again (I also tried to wipe Dalvik and Cache only)

6) Rebooted the system

Once I reboot the system the Redmi logo appears with the "powered by Android" underneath and after 5 seconds the phone reboots itself and then goes back to the recovery :(

What do you guys think I'm doing wrong?

What I did so that it would not happen to me again that was all they recommend in these post:

1.- Thread '[GUIDE][TWRP] How to keep TWRP V11.0.4.0 working on MIUI V12.0.5.0 or higher MIUI versions in MERLIN ? (Xiaomi Redmi Note 9 / Xiaomi Redmi 10X 4G)' https://xdaforums.com/t/guide-twrp-...omi-redmi-note-9-xiaomi-redmi-10x-4g.4223077/
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] Flying_Scotsman:
The first boot is perhaps critical. The behaviour may change depending on background MIUI version. My idea is that you try to be in control of first boot. Can you find an earlier point (perhaps when you first see "powered by Android") where you force stop? I have logged dozens of fails, but only 2 success, so I sure do not know the answer!

Edit, with another success logged, thanks to the help of @VD171 to have the device correctly prepared , I will just add that the Force stop trick is based on my experience with Samsung. What I now found is that as long as you never allow a boot into system from the very start, allowing a natural boot did work for me on another ROM. (untested on this ROM atm)

Im also stuck at fastboot using TWRP 3.4.2b-1213, after installing rom, doing the wipe... Goes back to fastboot... Followed the instructions to get out of the loop, but it doesn't work.....tried to make it boot again in the redmi screen with no sucess, only able to go into fastboot or TWRP.....☹️

I just installed it today(Redmi Note 9 NFC), so far works great, and it's smooth. and most importantly Xiaomi debloated,

Camera app Pro mode is missing few options like shutter speed and manual focus, but you can easily replace it with 3rd party camera apps like ProCam X, The phone shows up as a pixel 5, so you get all the goodies.

Great job!

You mean fastboot? Install twrp custom recovery
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] woahitspaulo:
thanks, I've wasted wasted quite a while to make it work...

had to flash the stock rom V12.0.3.0 with the MiFlash that i've found on https://www.getdroidtips.com/redmi-note-9-europe-stable-rom-update/

there is a vbmeta and twrp around in this forum

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

fastboot flash recovery .\TWRP-RedmiNote9-V12.0.6.0.QJOMIXM-20201213-wzsx15-sanja56\recovery.img

fastboot reboot recovery

then on TWRP I've enabled the option to prevent removal on advanced, wiped cache and the other stuff and enable adb sideload mode, it needed a few tries.

adb sideload .\PixelPlusUI_3.5_merlin-11.0-20210523-0725-OFFICIAL.zip

LOL its fine, This rom is phenomenal in this phone.
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] woahitspaulo:
yeah, I was surprised on how slow this phone was (it's my brother's phone). I'm still daily driving an A2 lite with the stock rom (Android one) but as support will be ending soon I'll switch for something like this. It feels so smooth now and the GCAM works wonders.
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] infinitumomega:
Thanks @woahitspaulo, I tried a PBRP recoveries as well with little success, but this is a nice succinct summary of the steps. To install Magisk I extracted the boot.img contained in the release zip file, patched it via the Magisk app and flashed it again with

fastboot flash boot ./patched_boot.img

.

And big thanks to @Evan_Ferrao, @sourav24071999 and the rest of the PPUI team! My phone runs much better now and I look forward to future updates of the ROM :D

[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] infinitumomega:
I've been running the ROM for a few days now but finding that it freezes or gets slow after a while. I'm not sure what the cause is, but my device is the 3GB edition. I've found that setting CPU governors to performance helps a bit but not enough.

I don't have an example now, but certain videos just do not want to load, possibly because some hardware codec can't be accessed, I'll let you know if I find it.

Let me know if there are any logs i can provide to assist you guys.

Thanks so much for getting us this far. Please keep up the good work :))
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] infinitumomega:
I think I found the problem. I was using Adaway with Magisk systemless hosts file which seems to be what was slowing my phone down.

edit:

Might be related to this issue https://github.com/topjohnwu/Magisk/issues/3171

I see there's a kernel patch mentioned at the bottom. Might be useful as a fix.

You can use adguard dns as alternative, or "vpn"-ed adaway, I'd rather the former. Dns server is sometimes down, if you get any troubles can't connect to internet, try to have private dns disabled and check the dns status.

Hello, i found this rom interesting but i am on stock MIUI 12.0.8 and unable to find any custom recoveries for this miui version. Can anyone guide me on how to get it installed ( i have already unlocked bootloader ).. Is this doable by downgrading to certain MIUI version ?
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] vagelis199:
So far I found only one bug. it's with ADB it only works once after you enabled Developer Mode and USB Debugging. You have to disable Developer Mode and re-enable it for it to work again,

Also while having Developer Mode Enabled, using the device to transfer files is not working, it goes back to just charging. To make it work you have to disable developer mode.

I found something not sure if it's a bug or my phone is broken (even tho is almost brand new) when NFC is enabled and you are using the main mic there's a constant popping or clicking sound in intervals, like pop ,pop , pop ,pop, its sound like a ping-pong ball, once NFC is disabled it disappears,

Hey so, i recently got a Mi9 and decided to do a system change, however, it wasn't as smooth as other devices.

After waiting 7 days, i got my Bootloader unlocked, and i managed to flash TWRP, however, file names were garbled, and ADB Sideload would act up, i managed to bypass that and flash the ZIP via sideload, but i still can't boot into the system. It goes straight to Fastboot after the Redmi logo appears, along with the Unlocked Padlock at the top.

Sure i can use the Xiaomi Flash tool and revert the system but i don't want to use MIUI, i want to use AOSP / Something Pixel-like

Any ideas how to fix that? My phone was runnning MIUI 12.0.10.0 QJOEUXM, but the TWRP for 12.0.8.0 apparently worked fine, along with the vbmeta provided.

I don't wanna unbrick it by reinstalling MIUI, i want to use a custom ROM.

EDIT:Had to re-flash MIUI to unbrick, and now, trying to flash that ROM, it seems like it will always get stuck before even starting any steps (It just show PPUI and nothing else).

What is the secret to flash a ROM in this device?

Hello guys! Are VoLTE and VoWiFi working? Any OSS firmware does not works with it, PPUI too. Maybe it depends on mobile operator?
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] NotVinx:
So I flashed this rom yesterday after getting my bootloader unlock and it went pretty smooth. For those who are facing problems while flashing, you must be missing something as it has a few more steps than normal flashing.

I used SHRP recovery and it flashed with no errors.

I was on latest MIUI Indian version so I downgrade to MIUI 12.0.3 Global before flashing.

I then rooted it with magsik. Safety net is working fine. And the device is encrypted.

Great rom, will update this after using it for a while. But the overall work is great. Highly appreciated. 👍

If you are facing some issues you can ask me for a detailed procedure.

I would suggest you to install anxcamera using magisk, installing camera apks didn't work for me (could not use my other lenses, no video capture, and so on).

Here's how to install:

First of all, install magisk:

* unzip this ROM, get your boot.img and patch-it using magisk app, flash your patched boot

in magisk:

** Add the 2 modules included in this comment (I flashed the 48MPFIx file first, just so you know)

MOD EDIT: Link Removed

That's all. By far this is the best camera app for this ROM (and maybe for every android 11 ROM for this phone)

PD: All the credit goes to the folks from ANX (https://camera.aeonax.com/), also, all those files come from their site.

PD2: You can also download those files there, just trying to save people some time

Give it a try

Ok I visited the faq page you provided, I have the twrp installed from there, its working fine, though one thing anyone new should note : the versions provided are UNOFFICIAL builds and are not verified directly by TWRP project, and the twrp fails to decrypt merlin even with correct password, there is no current fix for this, you will have to remove phone password and then boot into recovery to work around this problem.

[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] MidnightDevil:
Well, I followed the process of unlocking bootloader, flashing vbmeta, recovery, booted to recovery, erased system, flashed rom, rebooted, thats it.

Now I have another problem where twrp failed to decrypt and i can't copy anything to the sdcard while in recovery. I think I may need to do it through fastboot (clean system).
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] :
1. The bug of twrp not being able to decrypt even with correct password is an issue with the android 11. I have that issue as well, just remove the phone password before booting into twrp and you will be fine.

2. Did you flash any miui roms before flashing ppui ?

3. Do not flash any standalone vendor images even from xda, I have seen good phones getting completely hard bricked from doing that.

4. I will tell you the full update process I went through. :-

Install fastboot stock miui ROM (12.0.3 recomended). *DON'T LOCK THE BOOTLOADER IN THE PROCESS.* Watch some videos on youtube on using scripts for flashing miui fastboot roms, there ARE some extra steps in flasing the rom. After that you will have to do a format data in twrp. THEN reboot to recovery again, load the ppui rom in your internal storage. THEN WIPE DAVLIK, DATA, CACHE. DON'T WIPE INTERNAL STORAGE. Then flash the ppui ROM, and when the first boot logo shows up, hold the power button to force reboot to prevent bootloop.

Please tell me what happend afterwards ??

Flashed with nvdata recovery. Calls periodically stop making, although SMS is working at this time (Ukraine).

What could be the problem?
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] :
I don't really know much about nvdata recovery. But I don't have ANY problems with this ROM, seems like you messed something up while flashing. Don't do dirty flash, dont try to restore backups using recovery. If you have time, then start afresh, watch more tutorials, learn about this kind of stuff. Flash properly, I think you'll be good by then...

[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] Cutie Stacie:
The firmware is flashed as it should. And there are no problems, except periodic problems for calls.
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] MyBrainIsAStrainer:
I like this ROM because it seems to be the only one that actually gets regular updates. Kudos for that!

The problem is: I can't get it to work anymore. The initial release 3.4 (20210411) was fine. Ever since then, it does not work anymore. Just tried 3.7 (20210710) with the same result. I always followed the instructions (clean flash).

The problem is that the system won't boot. But this is not the usual boot loop, where it gets stuck on the logo. Instead, it doesn't even show the logo. After the bootloader, the screen goes black for a second (because it's resetting), I see the bootloader again, and then I find myself in recovery mode. Trying to boot into system again consistently produces the same result.

Once that happens, even flashing a new ROM (one that used to work) does not fix the device. I have to flash the entire original MIUI 12.0.1 ID via the fastboot method first. Then I can flash another custom ROM.

My guess is that some of the other partitions (of which there are way too many, if you ask me) get overwritten and that that's the problem. But I have no idea which one it could be or how to fix it.

Also, the problem does not occur with other ROMs that I've tried (Kraken, ArrowOS, LineageOS). For instance, I'm currently using LineageOS 18.1-20210710 and it works. It's just PixelUIPlus that does this.

Any ideas?
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] :
You are getting into dangerous territory here.(Atleast in my opinion.)

If you are not able to boot into the os, instead to the recovery, then there is something seriously wrong going on. So please, DO NOT TRY TO TINKER WITH THE FLASHING STEPS. DO NOT DOWNLOAD RANDOM VENDOR FILES FROM ANY YOUTUBE VIDEO OR WEBSITE. If you can, please go back to your stock ROM. BECAUSE IF YOU DAMAGE THE PARTITIONS ITSELF, THEN YOUR PHONE WILL BE BRICKED ! Please consider my advice. And dont try to get your stock recovery back. Just keep the twrp recovery.

*PREFERABLY, IF YOU ARE RUNNING LINEAGE OS OR ANY OTHER CUSTOM ROM THEN STAY.ON.IT.....

I've used it for two weeks on a merlinnfc, works pleasingly fine, I have another problem with the recovery(I use skyhawk): when through the recovery I search files, I find a strange tree, where there are many folders like root, external_sd or data, but all of them are completely empty. Basically, I cannot flash nor access my files from recovery. I'm not 100% sure if it's linked to decrypting problem, but I don't think so. I think it's linked to the option that you get during the first settings, where the rom asks you if the sd must be used as removable or a system media(this is the option I chose).

I got a more singular bug: recording a video, I can hear a strange noise from the mic. This happens both using Camera Go and the Whatsapp/Telegram/IG recorder.

Also, the 'Hey Google' doesn't work
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] vagelis199:
Solution for rebooting, not waking up and etc bug after updating to 3.9.

1. Download any firmware update from here https://xiaomifirmwareupdater.com/firmware/merlin/ (I downloaded the EU)

2. Drop the zip in your phone and reboot into recovery

3. Flash the zip using TWRP, wiping the dalvik cache is not required. just press reboot.

4. Done :)
