Part of POCO guides, PixelOS guides, 2025 guides.

PixelOS is what you flash when you want your Xiaomi hardware to behave like a

Pixel. On the POCO X7 Pro the Android 15 build has been worth the swap, and this

written version walks the same order I used, because on this phone the order is

the part that matters. Do the steps out of sequence and it will look like the ROM

does not boot. Do them in order and it comes up first time.

What is in the build

• GApps already included, so Play Store is there out of the box
• Signed build with OTA implemented, which means later updates do not need this

whole procedure again

• SELinux enforcing
• The build notes list no known issues and just ask you to send logs if you find

something

• If it refuses to boot, the advice is to reflash the latest firmware and go again

A signed build with OTA support is the detail I care about most, because it means

you are not on a dead end. Once you are up, updates arrive like they would on any

other phone.

What you need

• The PixelOS ROM zip for the POCO X7 Pro
• The vendor_boot image for that same build
• ADB and Fastboot driver installed on your PC
• Platform Tools
• A backup of your IMEI and your data, off the phone
• A charged battery and a good cable

The vendor_boot image has to match the ROM build. A mismatched one is a silent

ticket to a phone that does not get past the logo.

Step 1 - get into fastboot and confirm the connection

Boot to fastboot mode and run fastboot devices on the PC. A serial number means

you are good. Nothing at all means the driver is missing, and no amount of

retrying the later steps will fix that. Install the driver first.

Step 2 - flash vendor_boot to both slots

This is the single most important command in the whole guide:

fastboot flash vendor_boot --slot=all vendor_boot.img

The --slot=all part is not decoration. Both slots need the image, and skipping

one of them is how you get a phone that boots correctly once and then misbehaves

after an update.

Wait for it to report finished on both slots.

Step 3 - reboot and catch recovery

Run:

fastboot reboot

and hold Volume Up straight away. You have a short window here. If you miss it

and the old system starts loading, reboot and try again. Being early is fine.

Being late means starting over.

Do not use fastboot reboot recovery on this phone. The build notes warn that it

can brick the device, so take the Volume Up route every time.

Step 4 - format data

Format data before you sideload anything. This is a clean flash and it is

mandatory here. Dirty flashing this build is the direct route to a bootloop, so

please do not skip the format to save two minutes.

Step 5 - sideload the ROM

Go to Apply update, then Apply from ADB. On the PC, type adb sideload and drag

the ROM zip into the terminal window so the path fills itself in. Press enter.

Watch the progress percentage reach the end. Do not disconnect before it does.

Step 6 - extras, then first boot

When it asks whether to reboot back to recovery, say yes if you want to add

GApps or Magisk. This build already has GApps, so most people skip straight past

this. Then reboot to system.

The first boot takes longer than you expect. Let it work. Do not unplug anything

and do not force a restart.

Where people get stuck

• fastboot reboot recovery. The notes are explicit that it can brick this

phone. Use Volume Up after a normal reboot instead.

• Missing the recovery key window. Timing is tight. If you land in the old

system, restart from the vendor_boot step.

• Skipping the data format. This is the classic bootloop cause, and it always

looks like the ROM is at fault when it is not.

• The wrong vendor_boot image. It must come from the same build as the ROM

zip you are sideloading.

One honest note

The frustrating thing about this flash is how much of it is timing and

digit-holding rather than real complexity. The commands are short. The waiting is

long. I would rather you know that going in than spend the first reboot wondering

if you broke something when the phone sits on the logo for two minutes.

If it does not boot at all after a second honest attempt, reflash the latest

firmware and run the whole thing again from step 1. That is the recovery path the

build notes recommend, and it works.

If the driver install is the part that keeps stopping you before you even start,

the free Rom Flasher tool puts the ADB and fastboot driver in for you in a couple

of clicks. It is free, and the link is in the downloads section.

Full description from the video

PixelOS with the latest Android 15 build is running on the POCO X7 Pro — this is the full flash, from vendor_boot to first boot, done without any errors.

I took the latest PixelOS update for the POCO X7 Pro and flashed it end to end on camera. The vendor_boot file comes from the Telegram channel and the ROM is a GApps build, so Google's apps are already inside the package. It booted first try once the steps were done in order — the parts that trip people up are the reboot after flashing vendor_boot and the timing on the recovery key combo.

This is a clean flash, and it's mandatory here. Back up your IMEI, sort out the ADB driver before you start, and keep the cable connected until sideload reports done. If it doesn't boot afterwards, reflash the latest firmware and go again.

📱 Device : POCO X7 Pro (rodin)

📦 What's In the Build

• Clean flash is mandatory — no dirty flashing here
• GApps included, so it's Google-ready out of the box
• Signed build with OTA implemented
• SELinux is enforcing
• Known issues: none listed — the build notes just ask you to send logs if you find something
• Reflash the latest firmware if it refuses to boot

🛠️ What You Need

• vendor_boot.img and the PixelOS ROM zip
• ADB and Fastboot driver on your PC, plus Platform Tools
• A backup of your IMEI and your data
• A charged phone and a good USB cable

📝 Steps

1. Boot into fastboot mode and make sure the PC detects the device — install the driver if it doesn't.
2. Flash vendor_boot to both slots with fastboot flash vendor_boot --slot=all vendor_boot.img.
3. Run fastboot reboot and hold Volume Up straight away to land in recovery.
4. Format data first.
5. Apply update from ADB, then sideload the PixelOS zip.
6. Choose yes when it reboots back to recovery, flash GApps or Magisk if you want them, then reboot to system.

⚠️ Where People Get Stuck

• Using fastboot reboot recovery — the notes warn it can brick the phone, so use the Volume Up combo instead.
• Missing the recovery key window after the reboot; if you're late, start over.
• Skipping the data format and wondering why it boot loops.
