Important Warnings — Read Before Installing Android 15
Device-specific ROM: This Android 15 custom ROM is ONLY for the Redmi 10C. Do not flash it on any other device — it will brick your device.
Brick risk: Carefully follow every step in the correct order. Incorrect installation — such as flashing the wrong file, interrupting the process, or skipping the wipe — can permanently brick your Redmi 10C. TheUpgradeGuide is not responsible for any damage.
Complete data wipe: Installing this custom ROM erases everything on your Redmi 10C — apps, photos, contacts, messages, and files. Create a complete backup before proceeding.
Battery requirement: Charge your Redmi 10C to at least 50–60% before starting. An accidental shutdown during the flashing process can leave your device in a non-bootable state.
Warranty void: Unlocking the bootloader and installing a custom ROM will void your manufacturer warranty.
Pre-Installation Requirements for Redmi 10C
Make sure you have all of the following ready before starting the Android 15 installation on your Redmi 10C:

Full data backup: Back up all important data — photos, contacts, messages, app data, WhatsApp chats, and files — before starting the installation. Consider using Google Backup and Google Photos for cloud backup.

❌ “Error 7” or “Zip Verification Failed”
This usually means you’re flashing a ROM not built for your device. Double-check that the ROM zip is specifically for the Redmi 10C. Also ensure your TWRP version is up-to-date and compatible with Android 15 ROMs.
📱 No Mobile Data or Signal After Installation
You may need to flash the correct firmware (baseband/modem) before installing the ROM. Check the XDA Forum thread for the recommended firmware version for your build of LineageOS 22.
🔙 How to Restore Back to Stock ROM
If you want to go back to the stock ROM: (1) restore your Nandroid Backup via TWRP → Restore, or (2) download the official stock ROM from the manufacturer and flash it using the appropriate flash tool on your PC. This will completely restore your Redmi 10C to factory stock condition.
Frequently Asked Questions — Android 15 on Redmi 10C
Here are answers to the most commonly asked questions about installing and using Android 15 (LineageOS 22) on the Redmi 10C:
Is the Android 15 ROM for Redmi 10C stable enough for daily use?
The LineageOS 22 (Android 15) ROM for the Redmi 10C is an unofficial build. Core features — including phone calls, Wi-Fi, mobile data, camera, Bluetooth, GPS, and the fingerprint scanner — work well in most builds. Some minor bugs may exist depending on the build version. We recommend checking the XDA Forum thread for the latest known issues before installing it as your daily driver.
Will installing a custom ROM void my Redmi 10C warranty?
Yes, unlocking the bootloader and installing a custom ROM voids the manufacturer warranty. However, since the Redmi 10C was released in September 2019, virtually all units are well past their warranty period, so this shouldn’t be a concern for most users.
Can I go back to stock ROM after installing Android 15 on my Redmi 10C?
Absolutely. You have two options: (1) Restore your Nandroid Backup through TWRP Recovery to return to your exact previous ROM state, or (2) Download the official stock ROM from the manufacturer’s website and flash it using the appropriate flash tool to perform a clean restore to stock firmware.
Which GApps package should I use with Android 15 on Redmi 10C?
You can choose from four popular options: LiteGApps (recommended for minimal footprint), NikGApps (offers granular control over which Google apps to install), MindTheGApps (balanced package), or BiTGapps (lightweight alternative). All must be the ARM64 variant for Android 15 (API 35). Read our complete GApps compatibility guide to choose the best option for your needs.
Do I need an unlocked bootloader to install Android 15 on Redmi 10C?
Yes, an unlocked bootloader is a mandatory prerequisite. Without it, you cannot install TWRP Recovery or flash any custom ROM. Use the manufacturer’s official unlock tool to request a bootloader unlock. The process typically involves a waiting period before the unlock is approved.
Does the Android 15 ROM support the Redmi 10C’s fingerprint scanner?
Yes, in most LineageOS 22 builds for the Redmi 10C, the fingerprint scanner works correctly. However, functionality can occasionally vary between different build versions. If the fingerprint scanner isn’t working after installation, try updating to the latest build or check the XDA Forum for any required patches.
How do I update the Android 15 ROM on my Redmi 10C after installation?
To update to a newer build of LineageOS 22: Download the latest ROM zip from the LineageOS download page, transfer it to your device, reboot into TWRP, and flash the new ROM zip over the existing installation (this is called a “dirty flash”). Then wipe cache/dalvik and reboot. A full data wipe is usually not needed for minor updates, but always check the XDA thread for update-specific instructions.
Is the Xiaomi Mi CC9 the same as the Redmi 10C for custom ROM installation?
Yes, the Xiaomi Mi CC9 and Redmi 10C are the same hardware device sold under different names in different regions. The Mi CC9 was the Chinese variant, while the Redmi 10C was the global/international variant. Both use the exact same ROM, TWRP recovery, firmware, and kernel files. You can follow this same guide for either device.
