Before downloading any file, you must identify your exact sub-model. Hisilicon produced three major revisions, and firmware is not cross-compatible.

Critical Warning: Flashing the wrong fastboot.bin, bootargs.bin, or recovery.img will permanently brick the device (unless you have a JTAG programmer).

Warning: Using the wrong firmware can hard‑brick your box. You must match:

| Problem | Likely Cause | Solution | |---------|--------------|----------| | Flashing fails at 2% | Wrong USB cable or driver | Use USB 2.0 port, reinstall HiUSBBurn driver | | WiFi doesn’t work | Mismatched WiFi driver | Open box, check chip, find matching firmware | | Remote control unresponsive | Different remote.conf | Replace /etc/remote.conf with correct one | | Stuck at boot logo | Corrupted boot partition | Reflash only boot.img via fastboot |

Before flashing anything, back up your stock firmware in case you need to return for warranty or unbrick.

Using adb + dd (root required):

adb shell
su
dd if=/dev/block/mmcblk0 of=/sdcard/full_backup.img bs=1M count=3800

Using USB Burning Tool: After connecting, click “Read” (not “Start”) and save as stock_backup.img.

Store this on a cloud drive. Without it, you cannot revert to your OEM remote config or MAC address.

The HI3798 chipset is aging, but thanks to dedicated developers on 4PDA and Telegram, firmware is still actively released. Whether you are trying to fix a boot loop, recover lost Wi-Fi, or simply remove the pre-installed malware from your cheap IPTV box, the correct HI3798 firmware transforms a sluggish device into a capable 4K streamer.

Final Pro Tip: Before flashing any new firmware, always back up your current NAND full dump using the "Read" function in HiTool. Store that backup on a cloud drive. That is your insurance policy against a permanent brick.

Remember: The thrill of a freshly flashed Android TV box is immense, but patience and exact file matching are your best tools. Good luck!

The Hi3798 is a family of 64-bit ARM Cortex-A7/A53 (depending on variant) multimedia processors from HiSilicon, designed for set-top boxes (STBs), smart TVs, and media players. Common variants:

They support 4K H.265/H.264 decoding, HDMI 2.0, Ethernet, Wi-Fi, and Android/Linux.

Best for: OTA updates or converting from Android 7 to 9 if you have a update.zip.

Requirements: FAT32 formatted USB drive (8GB max), remote control.

Steps:

Yes, but only if:

No, if:

Performance tip: For an old Hi3798M (V100), stick with Android 5.1. For MV300/MV310, Android 9 ATV (Light version) is excellent.
