Redmi 14C / POCO C75 / Redmi A3 Pro (lake) HyperOS 2 Android 15 Fastboot ROM Download
The Redmi 14C, POCO C75 and Redmi A3 Pro share the internal codename lake and target budget users who want a big display, solid battery life and NFC at a low price. The Redmi 14C 4G NFC variant, for example, packs a 6.9‑inch 120 Hz IPS screen, MediaTek Helio G81 octa‑core chipset, 4–8 GB LPDDR4X RAM, 128–256 GB eMMC 5.1 storage and a 50 MP main camera powered by a 5160 mAh battery with 18 W fast charging.
Across Xiaomi’s HyperOS 2 lineup, owners frequently complain that after updating to Android 15‑based builds, their phones run hotter, drain faster in standby and sometimes lag more than on earlier versions, particularly in the days right after installing an OTA. These issues are usually linked to background optimization, early firmware bugs and power‑management changes rather than pure hardware faults, so installing a clean, region‑correct Fastboot ROM is one of the most reliable ways to stabilize a Redmi 14C / POCO C75 / A3 Pro.
The HyperOS 2 Android 15 ROMs below cover China (VGTCNXM), Global (VGTMIXM), EEA (VGTEUXM), Indonesia (VGTIDXM), Russia (VGTRUXM), Taiwan (VGTTWXM) and Turkey (VGTTRXM) devices under the lake codename. These full Fastboot packages are designed to fix bootloops, recover from failed OTAs or mods, and give lake users a clean, up‑to‑date Android 15 base with the latest stable HyperOS 2 branch for their region.

Flashing Requirements
- 💾 Backup data: Fastboot flashing will usually erase apps and internal storage, so copy photos and important files first.
- 🔋 Battery above 50 %: Ensure enough charge to avoid shutdowns that can corrupt partitions and hard‑brick the device.
- 💻 Windows PC & USB‑C cable: You need a Windows computer, Xiaomi USB drivers and a reliable cable for Mi Flash or fastboot.
- 🔓 Unlocked bootloader: Use Xiaomi’s official unlock tool before flashing any lake_*_images_*.tgz ROM.
How to Flash the Firmware
Method 1: Xiaomi Mi Flash Tool (Fastboot ROMs)
- Install tools & extract ROM: Install Xiaomi USB drivers and Mi Flash Tool on your PC, then extract the desired Fastboot ROM (for example, lake_global_images_OS2.0.203.0.VGTMIXM_…) to a simple folder path.
- Enter fastboot on your lake device: With the bootloader unlocked, power off the phone, hold Volume Down + Power to enter fastboot, and connect it via USB‑C.
- Load the firmware: Open Mi Flash Tool, click Select and point it to the extracted ROM folder containing the images and scripts.
- Choose “clean all” and flash: Select a mode like “clean all” (avoid relock), click Flash, and wait while the tool writes all partitions.
- Reboot and let it settle: After Mi Flash finishes, let the phone reboot; the first Android 15 HyperOS 2 boot can take several minutes while apps are optimized.
For a complete, step‑by‑step Mi Flash guide with screenshots and troubleshooting, see: Full Tutorial: Flash Xiaomi Firmware with Mi Flash Tool.
Method 2: Fastboot Script (flash_all.bat Style)
- Install Android platform‑tools: Download Google’s platform‑tools and confirm the fastboot command works in your terminal.
- Unpack the ROM completely: Extract the .tgz file until you see partition images and scripts such as flash_all.bat.
- Connect in fastboot mode: Boot the lake device into fastboot and connect it; run fastboot devices to ensure it is recognized.
- Run the appropriate script: Execute the “flash all” script that does not relock the bootloader and wait for all partitions to be flashed.
- Finish setup and monitor: After reboot, complete setup and monitor heat and battery life over a few days as HyperOS 2 finishes background optimization.

Frequently Asked Questions (FAQs)
What lake problems can these ROMs fix?
Flashing the correct regional ROM can resolve bootloops, random reboots, severe lag, failed OTAs and many HyperOS 2 software issues like abnormal battery drain and overheating on Redmi 14C / POCO C75 / Redmi A3 Pro.
How do I confirm my phone uses the lake firmware?
Check Settings → About phone → Version and verify that the codename is lake or that online firmware tools list your exact model (Redmi 14C, POCO C75 or A3 Pro) under lake before flashing.
Which file should EEA or Global users pick?
EEA users should choose ROMs ending in VGTEUXM, while worldwide non‑EEA models generally use VGTMIXM; flashing any other region can cause network or OTA issues.
Do these updates fix HyperOS 2 battery drain on Redmi 14C?
Clean‑flashing a stable Android 15 build often improves extreme drain and heat reported right after OTAs, but overall endurance still depends on usage, signal and app behaviour.
Can I cross‑flash China VGTCNXM on a Global VGTMIXM phone?
Cross‑flashing between regions is technically possible with an unlocked bootloader but risks broken OTA updates, band issues and potential bricks if the bootloader is later relocked, so it is not recommended.
