Here is the forum-style post for the firmware dump. Subject: [Download] Geant GN-HD90 Original Firmware Dump (ZIP) Hello everyone,

Use the official Geant Upgrade Tool to flash the bin file via a Null Modem cable.

If the box is dead (red light only), use a CH341A or similar SPI programmer to flash the 8MB chip directly.

If the box is still responsive, rename the file to G_MS-90.bin (if required by your loader) and update via the menu.

This is the raw flash memory dump (.bin) compressed into a .zip file, ready for technical recovery. Model: Geant GN-HD90 Format: ZIP (containing .bin file) Type: Original Factory Dump
