Initial list of names taken from http://iradioforum.net/forum/index.php?topic=2099.msg18986#msg18986

The Venice modules run a MEOS operating system on a Imagination Technologies META processor.

None of the flashing methods described here work with the .isu.bin firmware files from this repository.

The .isu.bin file cannot be used as firmware update - some bytes need to be stripped off the beginning.

One user reports that the first bytes up to 0x7B must be removed from the ir-mmi-FS2026-0500-0653.2.11.19.EX70719-1B2.isu.bin to get a valid .sap.bin update file.

The .sap.bin update file thus begins with

05 00 10 00 10 A8 0A 00 00 B0 0A 00 06 02 1F 2B

Another user reported that for a FS2026-0500-0277, the first bytes up to 0xE9 had to be removed.

Removing the first bytes up to 0x7B works here, too.

The generated .sap.bin file then begins with ir-cui-FS2340, which in hex is

69 72 2D 63 75 69 2D 46 53 32 33 34 30

Some radios (e.g. FS2026-0500-0487) have a firmware upload form on their web interface.

At least the FS2026-0500-0487 wants a firmware file with a .sap.bin instead of a .isu.bin file extension. When renaming the .isu.bin to .sap.bin and uploading it, an error will be shown:

FILE CHECK FAILED

Uploading a prepared .sap.bin file (see above) will probably work.

Some users have reported that connecting the radio to the PC via a special USB-A-to-USB-A male-to-male cable puts the device in the "Device firmware upgrade" mode.

The PC lists the radio as following USB device then:

10a4:b784 Frontier Silicon Test DFU device

dfu-util can then be used to upload the firmware.

DFU mode available on:

• FS2026-0500-0388
• FS2026-0500-0653
• FS2340-0000-0170

DFU mode not available on:

• FS2026-0500-0286

At first, the .isu.bin must be converted to a .sap.bin update file - see above.

Steps to flash new firmware:

1. Radio must show "Waiting for PC wizard"
2. Connect radio to PC via USB
3. Check that the radio is found with dfu-util -l
4. Upload firmware to radio: dfu-util -d 10a4:bf8d -U myfirmware.sap.bin

A user reported success in repairing a non-working radio using dfu-util. The radio was not booting normally and just showed "Waiting for PC wizard".

1. Attach radio via regular USB cable

dfu-util -l
Found DFU: [10a4:c2aa] ver=0000, devnum=1, cfg=1, intf=0, path="0-1", alt=0, name="UNKNOWN", serial="00000001"

2. Load firmware from radio: dfu-util -U radio_firmware.bin
3. Identify radio firmware version by opening radio_firmware.bin in a hex editor. In this case the radio binary started with the string "ir-cui-FS2340-0000-0170_V4.5.7.e518da-1A10.bin"
4. Download firmware from frontier silicon servers based on the instructions in this repository
5. Convert downloaded .isu.bin to a .sap.bin update file - see above section "Firmware preparation". In this case all bytes before the "ir-cui..." string have been removed.
6. Upload firmware to radio: dfu-util -D ir-cui-FS2340-0000-0170_V4.5.7.e518da-1A10.sap.bin

After turning the radio off and on again, it booted correctly.

A user reports that he downloaded the firmware from his non-working radio by using a "CH341A programmer with soic-8 clip":

You must pull off venice module from the radio. When connecting the clip to flash you can read and flash the AT45D321 memory. It does not need to be desoldered from board, only clip must be connected.

Then he found the same start block in the firmware update file and copied all bytes from there on in the non-working firmware bin that was downloaded from the flash chip.

The "merged" binary was then flashed onto the chip, and the radio worked again.

FS2026 firmware is LZO compressed.

Known firmware versions are listed in known-versions.txt.

Run update.py to automatically check for updates of existing firmware files.

It seems that Frontier Silicon changed download URI and firmware format for FS2340 devices.

Another difference is that the firmware is encrypted. After the enco line some unknown binary content is following. Most likely the key to decrypt the firmware is placed inside the device during production.
