[Xiaomi 11 Lite 5G NE] MFN77:
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

PixelOS_lisa-12.1-20220622-1650.zip" (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 fw_lisa_miui_LISAGlobal_V13.0.4.0.SKOMIXM_0508eaacfa_12.0.zip" (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!!!
