Custom Kernel Downloads | Poco F3/ Mi 11X/ Redmi K40 (Alioth)
The kernel is key to Android performance – it’s the software that lets the hardware and operating system work together seamlessly. On the Poco F3, the kernel carefully controls the powerful Snapdragon 870 processor based on what you’re doing – gaming, browsing, etc.
For intense tasks like 3D mobile games, the kernel ramps up CPU and GPU frequencies so more calculations happen per second, generating slick graphics but also consuming more battery. During lighter use like social media, it slows things down to save power.
What is a custom kernel?
Now to “custom kernels”. Developers can tweak the F3’s original kernel software to optimize it even further. A customized kernel specifically built for the Snapdragon 870 chipset could potentially give your device an extra performance boost.
However, sometimes custom kernels can cause battery drain, performance drops, break hardware features, or even soft-brick the device. So you have to be careful choosing custom kernels for your device. Flashing kernels made for different devices can corrupt the storage and cause hard bricks to your device.

Guides to install a custom Kernel on Poco F3/ Mi 11X/ Redmi K40
Installing a custom kernel is easier than you might think. Follow the easy guide to install a custom kernel on your Poco F3 (alioth).
Step 1: Make sure the Kernel you are about to flash supports your current ROM (such as MIUI, or AOSP)(Read details)
Step 2: Download the Kernel ZIP file from the official sources we have given to you.
Step 3: Boot Into Custom Recovery
Press and Hold the Volume up and Power key at the same time until you see the recovery logo.
Step 4: Backing up necessary partitions
Make sure you have backed up the boot partition so that you can restore the stock kernel if anything goes wrong. For good measure, backup the dtbo partition (basically dtbo.img file) too. This is because sometimes you may face issues like broken multi-touch, refresh rate issues, etc. Restoring the dtbo partition can fix those problems.
Step 5: Flashing the Kernel ZIP file
In your recovery browse to the Kernel ZIP file and install it as a flashable zip.
Step 6: Rebooting the device
Go to the reboot menu from your recovery and choose the System Reboot option.
Congratulations! You have successfully installed a custom kernel on your Poco F3. Now wait for the device to complete the reboot.
If your device doesn’t boot don’t panic. First, reboot into recovery ( follow Step 3) and restore the boot and dtbo partition. Then reboot into the system. This will install the stock kernel and your phone will boot normally.
The Final Verdict
A custom kernel can improve the device performance by a quite margin. If you are a gamer, you will surely appreciate the performance increase by installing a good gaming-centric kernel on your Poco F3. But it is not recommended if you don’t have experience or knowledge of installing custom ROMs and such topics.

He uses custom roms, modded firmwares, system modification modules etc to see how much better the performance gets with a optimized software on any given hardware.
In 2013, before the Android the wave in smartphone industry, he used a couple of Nokia Symbian OS powered smartphones. He used to perform hacking to the OS and unlock many features. It was a very popular process like jailbreaking an iPhone and unlocking bootloader of Android Phones. He feels nostalgia for that time.
Muhammad Minhaz is now a tech journalist as well as tech blogger. He wants to let others know the beauty of Android being an open-source operating system. He currently uses Redmi K30 Pro as his daily driver custom roms and a lot of system modifications.
Minhaz previously has written tech news and articles for ProjuktirPata.com, a tech website on Bangla language. Now with that expertise and experience he has gathered through years, he started writing for AndroidStory on July 2022. He covers tech news, custom rom updates, Android OS features, upcoming smartphones leaks and so on.
In his pastime, Minhaz loves to watch tech videos, reviews of smartphones gadgets, etc. He is also an astrophotographer. He uses his smartphones for stargazing, also to prove the true potential of smartphones.
He is so into astrophotography that he astro-modified his Redmi Note 7 Pro which seems to be first time done ever. It's very popular technique to capture more light data from deep space with traditional cameras. But no one seems to have it done with smartphones. This proves his passion, dedication and expertise on smartphone technology and astrophotography.
