I have the same error:
Error applying update: 7 (ErrorCode::kInstallDeviceOpenError)
E: Error in /sideload/ (status 1)
When trying to install by sideload but I can't do the leave the OTA for 1 hour as suggested because no OTA update appears, it tells me that there is no update.
I have checked and reinstalled the suggested firmware but the problem persists

check if adb fastboot tools are up to date

No, I wasn't. But it doesn't solve the problem either I have updated fastboot and same error.
My clean install steps...
1. I extracted boot.img with payload dumper and loaded it with fastboot.
2. I did Format data wipe in recovery mode and restarted into recovery mode.
3. I installed the latest fw build with adb sideload and rebooted into recovery mode again.
4. I installed the last build with adb sideload and rebooted

Xiaomi 11 Lite 5g NE

So Ampere reports that the max current is 3000mA, which goes accordingly to the information on the charger itself. Voltage is always at around 4V. So, if I'm not mistaken, it's charging at 12W max which is nowhere near the peak of 33W.

Not sure what's happening here.

At 33% charge it starts off at just about 2000mA, goes up and down in the range of 1000mA-2500mA. It's definitely slower than on stock MIUI.

Im still experiencing random reboots and even full on crashes on the latest build. Did a clean flash when i installed it. The reboots are not so common anymore, but the phone can still crash when on the lockscreen or when checking notifications. Doing a hard-reset is the only way to get it to work again.

The latest update seems decent besides the occasional reboots like the user above pointed out.

I noticed however that the MIUI camera update made all of my GCam mods work poorly? All of my Gcam pictures now look like they have a weird softening+contrast boost added to them that wasn't there before. I'll be downgrading to 18th of July for the time being.

Thanks for the development so far, though. It's still impressive work.

    PixelOS Update! (11/07/2022)

    Dirty flash works, just sideload or flash from sdcard.
    OTA Update pushed to users on previous beta and stable builds.

    - Added OTA asserts so rom flashes fine for all users
    - Upgraded to Boot Control HAL to v1.2
    - Upgraded to boot header to v4
    - Fixed ViLTE calls
    - Misc optimizations and fixes

    - Merged July Security Patch (android-12.1.0_r11)
    - Fixed issues with HDFC banking apps detecting root access
    - Extended Applock support to various system apps
    - Added optional Daily data usage in expanded quicksettings
    - Updated per-app volume drawable to match other system elements
    - Improvements in statusbar icon paddings
    - Added toggles for vibration icon and old style mobile data indicators in Icon manager
    - Made battery & clock clickable again in quick statusbar header
    - Updated translations (thanks to everyone who contributed).

    Edit: You might get "Couldn't load Android system properly" screen after updating to the latest build, just hit "Try again" and it'll boot normally.
    If your phone doesn't recognise your password/pin/pattern on first boot, just reboot once and it'll be fine.
    hi, I'm trying to clean flash for the 1st time. I did fastboot flash boot boot-lisa-20220711.img then fastboot reboot recovery and I got an infinite boot loop.

    then I download an older version of the boot-lisa-20220513.img and flash it, I was able to get in the custom recovery screen. From the boot recovery version 20220513, can I apply the latest ROM version then apply the fw update I supposed? Will the ROM file automatically update the boot recovery to the latest after flashing the ROM ?
    Flashing full rom will update the boot image on its own.
    There's no correct order for flashing firmware, it can be done before or after flashing rom without loosing data.

    Why this happened? We switched to boot header v4 this month, tldr; recovery is no longer in boot image, it's stored in vendor_boot image. I was supposed to delete the latest boot image from sourceforge which I did later on.
    So you can use old boot image to boot to recovery and sideload rom, since the rom contains both vendor_boot and boot images, they'll get updated to the latest.

    Proper way of clean flashing roms with boot header v4 would be to flash boot and vendor_boot (contains recovery) image first, then reboot to recovery and sideload rom. This method is a bit more confusing to end user and has the same end result as the easier way of using the older boot image, so we'll stick to that.
    First, thank you for this fantastic ROM!

    Few bugs that I have found so far :
    1. Whatsapp web doesn't work in the mobile app. Mobile application doesn't allow you to open the camera scanner to scan the whatapp web QR code.
    2. Any app that allows you to login to the app via Fingerprint method doesn't register the fingerprint. The fingerprint registration screen comes for about 0.5 seconds, automatically vanishes and then the fingerprint registration / scanner doesn't work in the entire mobile even for lock / unlock phone. Reboot is the only option to make the fingerprint work for lock / unlock phone.
    I don't have any of these problems. In fact, I've been struggling to find anything wrong with this ROM but can't.
    I have been logged out of most of the accounts. Even after logging in it gets logged out automatically after like 20 mins( ex. Instagram). Login authorization is on loop and I can't log in to some apps including the XDA app.

    Is anyone facing this issue?

    ( I updated this version using OTA)
    Yep I'm facing the same issue. Just woke up to see WhatsApp was logged out.

    We need a fix ASAP.
    fixed build already exist, just waiting to release
    Someone tried the new 12.07 Update ?
    Is that the fixed build, to avoid logouts from the apps?
    I have updated. All problems have been fixed for me.

    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.

    /* 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

    It's not modded in any sort, the sources used by PE or most other roms are open source and anyone can fork them and modify them according to their requirements, that's exactly what I did. This is not a GSI/ ported rom, it has been properly compiled from the sources.

    PixelOS Pre-Release Build (31-05-22)

    Just a quick Pre-Release build before the new security arrives, we've managed to fix OTA and a few other major issues. You might find a few new features after digging in a little, I'll be writing full changelog for nerds with a proper release build (tldr; better battery life and stability).

    You can always dirty flash either via sideloading or sdcard, latest global stable firmware recommended. For users who're planning to clean flash, you can use previous build's stable recovery for flashing this build.
    You'll be able to dirty flash next release build over this once its out (probably after June security patch rollout).

    This build also includes the new variable refresh rate implementation from AOSPA by arter97, here's his explanation on how it works
