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.

    Hi, I didn't have time to update XDA thread for Android 13 update, I'll try doing it tomorrow and will elaborate current state of ROM and what we've planned for later.
    Hey @whyredFire, when can we expect the beta release of A13?
    New build has some performance issues, mainly occasional stutters in both the home and lock screen. Seems like rapidly changing apps, going back to home or just generally quickly triggering animations freezes the UI.

    I'm experiencing the same thing. I've also had sudden reboots when using the camera, usually after taking a third or fourth picture. Everything freezes and the phone goes completely dark and after a while I see the boot screen with MIUI-logo and the unlocked padlock. The last picture(s) taken are usually corrupted after this happens.

    Everything else works great and the batteri life is good as long as AOD is off.

    I updated from previous build using OTA.
    Try Reflashing !
    1. Reboot to recovery ( pixel os recovery )
    2. Adb sideload
    3. Flash latest firmware via sideloading
    4. Reboot
    Same thing happened with me and I flashed firmware this way and now Bluetooth working.
    Ty it worked
    Thanks mate but the way i see that i am asking if a particular feature is working on this ROM or not hende i believe i am in the correct thread

    There is an unofficial thread for Orange fox for this devic and it is somehow active and i will ask there as well
    I get ya mate. I've tried unsuccessfully to get OrangeFox working on the previous build of PixelOS so I'm assuming it definitely won't work on this release.
    The annoying thing is, OrangeFox worked perfectly on PixelOS 2 releases ago. I used it and loved it, hence why I tried so hard to get it running again on the previous build, but all I did was mess up my PixelOS installation and I had to further and flash everything from scratch.
    Hope that helps 👍

    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

    Device Specific Issues:
    • So far, everything is working
    • Permissive SELinux

    Could you send a more detailed installation tutorial please?
    After struggIing a little bit I've finally done it. I didn't have any knowledge about any of it before doing this. So I'm not an expert but here is a more detailed guide:

    - Assuming you unlocked your bootloader. If you didn't, first you need to unlock it: Bootloader Unlocking Guide

    - Download the Latest Android Platform Tools and after exctracting it, move it to the main "C:" folder.

    - Download Recovery (boot.img) and move it to the same "Platform Tools" folder that we copied to the "C:"

    - Download ROM and don't exctract it or rename it. Also move it to the same folder.

    - Download Latest Firmware and also move this to the same folder that we copied to the "C:"

    - Download Mi Flash Tool. After downloading it, open the program and select the driver tab and install it.

    - Activate the Developer Options in your phone by Settings > About Phone > Tap on MIUI Number 7 times.

    - Search "Developer Options" in the settings and open it. There is an "Usb Debugging" option, enable it.

    - Connect your phone to the PC. And choose the File Transfer Mode from your phone's notifications.

    - Turn off your phone. After that press the Volume Down + Power Button together a few seconds until you see it enter into the Fastboot mode.

    - Open the Platform Tools folder that we moved in to the "C:" and type "cmd" into the Windows Explorer's folder direction bar and press Enter.

    - Type "adb shell" in to the command prompt that opened. (If it didn't recognise the command, type ".\adb shell" and use ".\" before any command I give after this.)

    - Type "fastboot devices". You should see your device. If you couldn't, then check the drivers or install the drivers again from Mi Flash Tool. If you still can't see your device and also can't see it in the Device Manager(Windows) then you probably using a diffrent USB-C cable. Try using the original one. If it still didn't solve the problem, try a diffrent PC or an USB Output.

    - Type "fastboot flash boot boot.img". You should see it installing. Wait before it finishes.

    - Type "fastboot reboot recovery". You should see your phone entering into the recovery mode. If it didn't, press Power Button few seconds until it shot down. Then press Volume Up + Power Button few seconds until you see it entering into the recovery mode.

    - By using Volume Up and Down and Power Buttons you can navigate the recovery menu from your phone. So select "Wipe Data/Factory Reset" and confirm.

    - After that go back to the Main Menu and select "Apply update".

    - Open the command prompt from your PC again if you closed it and type "adb sideload" (the ROM file should be named this. If your file's name is diffrent, type that instead.)

    - It should start installing. If this didn't, then you probably missed some steps from this guide. So please check that if you have the latest Platrfom Tools(adb) and that you download it from the official site. Also don't open it from the PowerShell Window, open it from the "cmd" like I said and make sure that it's in the main "C:" disc. Also try closing and opening again your PC and your phone before proceeding the second time.If it didn't start after all this and said cannot read the file, then you should try this: Large Adress Aware Program .

    - Only do this next 2 steps if there is new firmware update or you are flashing this rom from any other rom. If you are just updating your ROM and there is no new firmware update, ignore this next 2 steps.

    - After installing sideload reboot to recovery again. Then go into the "Apply Update" again from your phone.

    - Open the command prompt from your PC again type "adb sideload" (the firmware file should be named this. If your file's name is diffrent, type that instead.)

    - After installing, navigate trough recovery menu again and select the "Reboot System".

    - It's Done!!!
    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.
