Firmware update

Install H9 Toolbox Firmware, or restore official v1.0.38, through the TD-H9 vendor HID recovery mode. H9 Toolbox Firmware is stock v1.0.38 plus an app loader: hold Back for a menu of apps (an onboard APRS client, Brick Breaker and more) that you add and remove over Bluetooth in the App Manager, together with your boot logo. The package downloads from H9 Toolbox and is checked against its exact hash. Your radio backup stays in your browser and is never uploaded.

Before you begin

Install and restore through this page have been tested on one TD-H9 from macOS. A failed update can leave the radio unable to boot. Keep a reliable recovery method available.

Before writing, the page backs up the radio (Backup radio in step 03); keep that file. The HID backup reconstructs flash from CRC queries. On stock or H9 Toolbox firmware it takes a few seconds; on other firmware it can take about an hour. HID cannot read or write the protected first 0x5000 bytes. A Bluetooth channel .img is not a firmware recovery backup.

H9 Toolbox Firmware installs over the exact stock v1.0.38 main image, the original Brick Breaker, or any earlier H9 Toolbox Firmware build; the page refuses any other starting image. If you update older firmware to v1.0.38, recheck channels and settings afterward.

Connect radio

Disconnected

Turn the radio off and connect a data-capable USB-C cable.
Hold PTT + 2 while powering on. The screen stays blank and the top LED turns green.
Click Connect radio and choose the JieLi HID device in the browser’s list.

Keep the radio connected in HID mode until you finish step 03.

Select firmware

✓ SelectedH9 Toolbox Firmware for v1.0.38Stock v1.0.38 with the app loader and the Bluetooth service the App Manager uses. Checked against its exact hash before any radio access; upgrades earlier H9 Toolbox builds and the original Brick Breaker directly.

✓ SelectedStock Type-C v1.0.38Reads the pinned ZIP from the third-party TDH9 mirror and verifies both the ZIP and extracted firmware hashes.Or select a local stock .fw

Restore point, optional: a stock backup (.h9hid or raw .bin)No backup selected. You can create one after connecting.

No firmware selected

You usually do not need a file here. If the radio runs stock, its backup is the restore point; if it runs any H9 Toolbox Firmware build or the original Brick Breaker, the restore point is official stock v1.0.38, rebuilt from verified files. Choose a file only for a radio with other firmware.

Write firmware

Back up the radio first: the backup downloads a recovery file of its current firmware in a few seconds (stock or H9 Toolbox firmware); keep it. Install then checks every sector on the radio (CRC only, no writes) and builds the exact plan; nothing is erased unless that check passes.

I understand this experimental update may damage my radio. I saved a recovery backup and have a recovery method.

Connect the radio in step 01.

Restore writes your restore point’s firmware sectors back and checks their CRCs. Your channels and settings are never changed here; to back them up, use the Bluetooth programmer.

Install apps and a boot logo

Bluetooth

Needs H9 Toolbox Firmware on the radio.

Disconnect USB and power-cycle the radio so it starts normally.
Open the App Manager in this browser and connect over Bluetooth.
Add apps (APRS, Brick Breaker…) and choose a boot logo, then Write to radio.
On the radio, hold Back for the app menu.

Open the App Manager

Apps and the boot logo live on the radio’s separate resource flash, so firmware updates (including a return to stock) keep them.
