After the release of TWRP modded by skkk (with A12 decryption support), last week Nebrassy released an unofficial version of TWRP with A12 decryption support.

Nebrassy is the current official maintainer of TWRP for the POCO F3, his unofficial TWRP version is open source and, at least for me, this version of TWRP is more trustworthy.

I decided to install TWRP-3.6.2-alioth-Nebrassy-24-06-22.img over the default recovery of PixelOS to finally make a full NANDROID backup of my device before trying new ROMs (or new updates).

Currently I'm on the last PixelOS version (the 20 Jun 2022 release). To install TWRP-3.6.2-alioth-Nebrassy-24-06-22.img I followed those steps:

  1. you need a PC with working ADB / platform-tools / fastboot utility (commonly a Windows PC)
  2. download the correct TWRP from this link (the link is mentioned here)
  3. move from the download folder the file TWRP-3.6.2-alioth-Nebrassy-24-06-22.img to your platform-tools folder
  4. restart the phone into fastboot mode and connect the phone with a USB cable to your PC
  5. from the platform-tools folder, open a CMD command prompt and run the command "fastboot devices": you should see a device plugged in and connected
  6. from the terminal, run "fastboot boot TWRP-3.6.2-alioth-Nebrassy-24-06-22.img"
  7. your phone will start in TWRP recovery only this time
  8. to make TWRP your permanent recovery, go to "Advanced > Flash Current TWRP" then reboot
Now, using an external USB-OTG storage, from recovery, you can backup your device.
If you are using a rooted device, after installing TWRP you have to install again Magisk (from TWRP is working as usual).

Hello everyone. This rom is pretty solid and butterry smooth. However I have a question to ask although it's not specific to this rom.
I am using the poco f3 with dual sim cards with this rom and before on miui. The issue is the signal. It fails to receive and make calls with both carriers 8/10 times, all the while other phones work fine in the same place. It also fails to use cellular connection most of the time.
Now, it was working fine before miui 13 and so I flashed this rom cause I thought it was a miui issue but the problem persists here as well. I tried everything I could and still there is no solution.
Is it a hardware issue or is there something I can do to fix it?

Have just installed this on my F3.

A couple of points which may be helpful:

1: when flashing recovery it flashed only to the b partition, so I had to do it again with "fastboot boot_a...".

2: It wouldn't boot into PixelOS recovery. Instead it would just go boot into MIUI. So instead I temporarily booted into Pixel Experience Recovery and sideloaded POS from there, which will therefore install PixelOS recovery.

Quick question. I want to disable 5g but instead of the simple 3g/4g/5g toggle I get this, which I don't really understand.

NR is 5g and I believe it is off by default

From last month I've been experiencing some strange behaviour of rom. Sometimes, when I want to unlock my phone the screen goes completely off and cannot be waken up until the restart of device.

Have anyone similar problem to mine?

I'm using the latest version of PixelOS.

It happened to me 2 times next to a clean install.
Never happened again. I have FW V13.0.6.0.SKHEUXM.

Hi guys,

I stayed off updates for a while due to bugs and my current version was perfect.

But now I am only seeing April update in system update, not the current June one.

Same here, 1 to even 2 times a day
I don't have this problem.
The only problems are that Always On is no longer really bright.
And when I unlock the phone, it stays dark for a moment until the brightness is turned up.
When switching off in standby, it takes a few seconds for the display to go out.

    So what happens now folks?

    Do we wait, or have to move on to another ROM (if yes, then which 'Pixel' will you guys go for)?
    No one has applied yet to be a new maintainer and once they do the process takes a few weeks.

    For now, either use the unofficial build or wait for an official maintainer - hopefully within a month or two.

    For me, nothing is broken on the latest official build so I'm sticking on that and hope someone takes over soon.

    Works fine on my phone.

    Does anyone know why the PixelOS page has been removed? (Error 404)
    The domain has moved to http://pixelos.net

    Hi. I have a few queries.

    1. I am using pixel experience plus rom on my mi 11x. Do I need to install miui global rom first and then install pixelos?

    2. Does pixelos for mi 11x have dolby atmos?

    3. Does wifi calling work?
    1. No
    2. No
    3. I think it does, haven't tried yet

    3. For me it doesn't work. Wifi calling is based on a ip sec tunnel to your phone provider. I can't see any tunnel set up when I tcpdump my phones traffic on my router.
    I also experience problems with 4G calling on my Youfoune (KPN Netherlands network) sim, I don't see the callers number. With a TMobile NL sim this works fine.

    PixelOS is an AOSP based ROM, with Google apps included and all Pixel goodies (launcher, wallpapers, themed icons, google sans fonts, Monet color based system wide theming, boot animation), a fork of OG Pixel Experience with improvements on the top of it. Huge respect to Pixel Experience team for their work, thanks to them for making this ROM possible.
    In short a fully functional Pixel Experience with just the right amount of essentials.

    Code:
    /* Your warranty is now void.
    *
    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at me for messing up your device, I will laugh at you.
    */

    Improvements over PixelExperience
    Performance improvements from ProtonAOSP
    Adopted screenshot sounds to ringer mode
    3-finger swipe to capture screenshots
    Double tap to sleep on lockscreen and status bar
    Added Screen Recording Customizations
    Added Advanced Reboot
    Allow disabling Screenshot Sounds
    Added Bluetooth headset battery indicator
    Spoofed as Pixel XL for Google Photos for unlimited backup in original quality
    Added themed icons for a lot of third party icons in stock Pixel launcher
    Added monet in power menu
    Exposed legacy WiFi and Cellular data QS tiles
    Added bluetooth battery level indicator on status bar
    Added NFC tile in QS for supported devices
    Added double tap/long press power button to toggle torch
    Reduced log spam verbosity
    A lot of under the hood UI fixes and improvements

    So, though I do not like MIUI... at all... I thought I had nothing to lose trying to use the batch script to load the xiaomi.eu ROM. It's a 4GB file but it didn't take too long and I extracted it, booted the phone to fastboot and ran the windows batch script. It seems to have worked, so I have a functional OS again. So I'm kind of back at the start. Can someone point me to an IDIOT proof installation How To for Pixel OS?
    1. download PixelOS -> https://pixelos.vercel.app/download/alioth
    2. download PixelOS Recovery -> https://sourceforge.net/projects/pixelos-releases/files/twelve/alioth/recovery/
    3. download Android SDK Platform-Tools -> https://developer.android.com/studio/releases/platform-tools
    4. unzip platform-tools_r??.0.0-windows.zip and copy PixelOS_alioth-12.0-2022???-????.zip and boot-alioth-2022????.img inside the unzipped folder (in the same folder where adb.exe and fastboot.exe are)
    5. power off phone and power on with power + volume down (going to fastboot)
    6. plug the phone to your computer and check if the phone is recognized: run from terminal (from the platform-tools folder) "fastboot devices" (you should see a device listed)
    7. run "fastboot flash boot boot-alioth-2022????.img" and after some seconds you should get a finished message, then unplug the phone from the computer
    8. reboot the phone in recovery mode ( power + volume up )
    9. do a "Factory reset" -> "Format data/factory reset" (you will loose all data, so do a backup before)
    10. go to main screen of recovery mode and select "Apply update" -> "Apply from ADB". Plug the cable to the computer
    11. run from the terminal "adb sideload PixelOS_alioth-12.0-2022???-????.zip" and wait the process to finish (reaching 100% from terminal - and Step 1/2 / Step 2/2 on the phone). Unplug the phone from the computer
    12. go to main screen of recovery mode and select "Reboot system now"
    You will lose TWRP (but at this time TWRP is not working with Android 12 encryption, so better use PixelOS Recovery. It'll support also OTA update).
    You need to have also the bootloader unlocked.

    Edited: fixed the command "fastboot flash boot boot-alioth-2022????.img" adding the missing the "boot" option.
