Installing a custom ROM on an older smartphone breathes new life into aging hardware, removing bloated manufacturer apps and replacing an outdated operating system with a clean, updated Android build. If you own an Infinix Hot 8 X650c, stock software support ended long ago, leaving your device vulnerable to security flaws and sluggish performance. By unlocking your bootloader, flashing a custom recovery, and installing a community-built operating system like LineageOS or Pixel Experience, you can reclaim battery life, speed up daily tasks, and run modern apps that otherwise refuse to install on Android Pie.
Let's dive straight into the hardware specifications, prerequisites, and exact flash sequence required to update your phone safely.
Infinix Hot 8 X650c Hardware Overview and Limitations
Before touching any system files, it's critical to know what powers your specific variant. The Infinix Hot 8 X650c runs on the MediaTek Helio A22 (MT6761) chipset, paired with 2GB or 4GB of RAM depending on your regional model. MediaTek devices are notoriously tricky to modify compared to Snapdragon equivalents because their bootloaders require specific scatter files and dedicated PC flash tools like SP Flash Tool.
If you try to flash a ROM built for the standard Snapdragon or different MT67xx variants, you will permanently brick your handset. Always confirm your exact model number by navigating to Settings, tapping About Phone, and verifying that the build string displays X650c.
Essential Preparation Steps
Skipping preparation steps causes the vast majority of botched installations. Take these precautions before connecting your phone to a computer.
- Back up user data: Flashing a custom operating system requires a complete internal storage wipe. Export your photos, documents, and contacts to cloud storage or a separate PC.
- Charge above seventy percent: A sudden shutdown mid-flash corrupts the preloader and partitions. Plug your phone into a wall charger if battery health is degraded.
- Install OEM drivers: Download and install MediaTek VCOM drivers on your Windows PC so the device is recognized correctly during the flashing state.
- Enable developer options: Tap your build number seven times in system settings, then turn on OEM Unlocking and USB Debugging.
Step 1: Unlocking the Bootloader
You can't flash third-party system partitions with a locked bootloader. Because Infinix uses MediaTek processors, unlocking differs from the standard fastboot method used on Google Pixel or Motorola devices.
- Power down your Infinix Hot 8 completely.
- Open the SP Flash Tool on your Windows PC and load the correct scatter text file matching the MediaTek MT6761 chipset.
- Select the Download Only or Format All + Download mode depending on whether you are doing a clean partition rewrite.
- Connect your phone via a reliable USB cable while holding the volume down button to trigger BROM mode.
- Wait for the green checkmark to appear, indicating that the bootloader flags have been successfully bypassed.
Step 2: Flashing TWRP Custom Recovery
With the bootloader open, you need a touch-enabled recovery environment to wipe partitions and install the new zip package. TWRP (Team Win Recovery Project) serves as the industry standard for this task.
- Download the dedicated TWRP recovery image compiled specifically for the Infinix Hot 8 X650c.
- Place the recovery image file on your computer desktop alongside the minimal ADB and Fastboot binaries.
- Boot your device into fastboot mode by holding power and volume up simultaneously.
- Open your command prompt terminal and type
fastboot flash recovery twrp.img, replacing the filename with your actual downloaded recovery file. - Disconnect the USB cable and immediately hold the physical volume up and power buttons to boot directly into the newly flashed recovery interface.
Step 3: Wiping Partitions and Flashing the ROM
Inside TWRP, you must clean out the old operating system fragments before installing the replacement firmware.
- Tap Wipe inside the main TWRP menu, then select Advanced Wipe.
- Check the boxes for Dalvik/ART Cache, System, Data, and Cache. Do not wipe Internal Storage unless you copied your ROM zip to an external SD card.
- Swipe the slider at the bottom to execute the partition format.
- Return to the main menu, tap Install, and navigate to your downloaded custom ROM zip file.
- Swipe to confirm the flash. If you plan to use Google Play Services, flash your chosen Open GApps package immediately after the ROM file without rebooting in between.
Post-Installation Setup and Optimization
Once the installation bar completes, tap the reboot system button. The first boot on a newly compiled operating system always takes longer than normal—sometimes up to fifteen minutes as Android builds its Dalvik cache.
When the setup wizard appears, connect to Wi-Fi and sign into your Google account. Because custom ROMs strip out manufacturer bloatware, check your battery settings and enable performance profiles if your chosen build includes kernel audiator controls.

Frequently Asked Questions
Can I revert back to the original Infinix stock ROM later?
Yes. You can flash the official stock firmware at any time using the SP Flash Tool and the original scatter firmware package for the X650c.
Will custom ROM installation break my mobile network data?
Most stable community ROMs include proper APN configurations, but if your cellular data fails to connect, you must manually input your carrier's Access Point Name settings under network settings.
Do I need a computer for every step of this process?
You need a PC for the initial bootloader unlock and custom recovery installation. Once TWRP is active, subsequent ROM updates can be flashed directly from an SD card on the phone.
Why is my device stuck on the boot animation screen?
A bootloop usually happens if you forgot to wipe the cache and data partitions before flashing. Force shut down the phone, boot back into TWRP, perform a factory reset wipe, and reflash the zip package.
