Hi3798 Firmware: The Complete Guide to Upgrading and Customizing Your TV Box
If you own a budget-friendly 4K Android TV box, there is a high probability it is powered by the HiSilicon Hi3798 chipset. Whether you have the Hi3798M V100, V200, or the CV200 variant, the firmware is the heart of your device.
Updating or changing your Hi3798 firmware can unlock better performance, fix annoying bugs, or even transform a locked-down ISP box into a versatile media center. Here is everything you need to know. Why Look for New Hi3798 Firmware?
The Hi3798 series is known for its excellent hardware video decoding (especially H.265 10-bit), but factory software often falls short. Users typically look for new firmware to:
Remove Bloatware: Get rid of pre-installed apps that slow down the system.
Upgrade Android Versions: Move from older versions (like Android 7) to more stable, modern builds. Gain Root Access: For deep customization and ad-blocking.
Fix Connectivity Issues: Resolve Wi-Fi drops or Bluetooth pairing errors.
Install Android TV (ATV) OS: Replace the standard "tablet-style" Android interface with a lean, remote-friendly TV interface. Identifying Your Specific Chipset
Before downloading any files, you must identify your specific version. Flashing the wrong firmware will "brick" your device (render it unbootable). Hi3798M V100: Often found in older, entry-level boxes.
Hi3798M V200: A very popular mid-range chip found in devices like the H96 Mini or various Huawei/Honor boxes.
Hi3798C V200: The high-end version, often found in premium players like the HiMedia Q10 Pro.
Check your "About Device" settings or use an app like AIDA64 to confirm your hardware ID. Types of Hi3798 Firmware 1. Stock Firmware
This is the official software provided by the manufacturer. It is the safest option but usually lacks the latest features. 2. Custom ROMs (Android TV / SlimBOX)
Developed by enthusiasts, these are the most popular downloads. Projects like SlimBOX often provide ported versions for Hi3798 devices, offering a much smoother experience, better thermal management, and pre-installed root. 3. Linux-Based OS (LibreELEC / CoreELEC)
If you only care about local media playback (Kodi), you can flash a Linux-based firmware. These bypass the overhead of Android entirely, making the Hi3798 run significantly cooler and faster. How to Flash Hi3798 Firmware
While methods vary by brand, most HiSilicon devices follow this general workflow: The "Reset Button" Method (USB)
Download the update.zip or the folder containing fastboot.bin, bootargs.bin, etc. Format a USB drive to FAT32. Place the firmware files in the root directory of the USB. Unplug the power from your TV box. Insert the USB drive.
Use a paperclip to press and hold the Reset button (usually hidden inside the AV port). While holding Reset, plug the power back in.
Release the button when the upgrade progress bar appears on your TV. The Hitool Method (Advanced)
If your device is "hard-bricked" (won't turn on), you may need to use HiSilicon Hitool on a PC. This requires a USB-to-TTL serial adapter and connecting directly to the motherboard's pins to re-flash the bootloader. Essential Precautions
Backup: If your box is currently working, use a backup tool to save your current partitions.
Check the Wi-Fi Chip: Many Hi3798 boxes use different Wi-Fi modules (e.g., RTL8189 or AP6212). Ensure the firmware supports your specific module, or your Wi-Fi won't work after the flash. Power Supply: Never interrupt the power during a flash. Where to Find Downloads?
Because the Hi3798 is an "open" platform used by many generic manufacturers, there isn't one single website. The best places to look are:
4PDA Forums: (The "holy grail" of HiSilicon firmware, though you'll need a browser translator). XDA Developers: For more mainstream Hi3798 devices. FreakTab: A long-standing community for TV box enthusiasts.
Here’s a useful, structured write-up on Hi3798 firmware — aimed at developers, advanced users, and anyone working with Android TV boxes or Linux-based STBs using HiSilicon Hi3798 series chips.
.img or .xml file) and flash.| Issue | Likely Fix |
|-------|-------------|
| Box stuck on boot logo | Wrong bootloader or mismatched fastboot.bin |
| No Wi-Fi / Bluetooth | Wi-Fi chip driver missing – find correct firmware |
| Remote not working | Replace remote.conf or sunxi_ir.kl |
| Can’t flash via USB | Need to short NAND pins (search for your PCB) or use UART |
| Boot loop after update | Clear cache & factory reset from recovery |
Follow this checklist to avoid bricking:
