PhoenixSuit should recognize the device. If it asks to force format, select Yes .
Possible to run if an underlying Armbian image exists, although secure boot mechanisms in cheap H313 boxes can make installation difficult.
Ensure the ROM matches your specific board configuration (especially the Wi-Fi/Bluetooth chip, such as RTL8723 or XF-622), or your wireless connectivity will stop working.

Upgrading your Allwinner H313 TV box with a custom ROM is the single best way to maximize the utility of an ultra-budget streaming device. By stripping away manufacturer limitations, optimizing system memory, and introducing an intuitive Android TV interface, you can seamlessly extend the lifespan of your device and enjoy a fluid, ad-free streaming environment. Always remember to verify your hardware specifications and back up critical files before beginning the flashing process.
Android Stock ROM vs Custom ROM: Which Is Best for Flashing?
Unlike Amlogic chips, the H313 does have a locked PBL (Primary Boot Loader), but it uses a non-standard DRAM controller. Without the original boot0 and boot1 partitions, a custom u-boot will fail to initialize LPDDR3/DDR4 memory – leading to a hard brick. PhoenixSuit should recognize the device
The TV box must be completely powered off and disconnected from its power brick before starting this step.
Flashing an Allwinner chip requires a specific set of hardware and software tools. Before proceeding, gather the following: Hardware Requirements
The progress bar will begin to advance from 0% to 100%. or disturb the device during this process. Ensure the ROM matches your specific board configuration
Many custom ROMs are essentially stock firmware that have been:
This typically indicates a mismatch between the custom ROM configuration and your device's motherboard revision or Wi-Fi chip. Boot back into FEL mode and attempt to flash an alternate variant of the ROM.
