---++ Firmware
   * The firmware for the Angora was never updated, however, the firmware for the Aigo E235 was. There are two firmware versions
      * [[http://rockbox.godevelopments.net/fw/E235_driver(eng).zip][English]] (No working sound in music and video everything else works)
      * [[http://rockbox.godevelopments.net/fw/E235_driver(chi).rar][Chinese]] (Everything works including sound)

---++ Firmware File Format
The Firmware Update file contains everything uploaded to flash (that's why it is exactly 4MB), it seems to consist of several images. Images found so far:
   * ROMFS: Starting at 0x40000. Contains [[%ATTACHURL%/fat_mount.rar][ROMFS]].%BR%This is a ROMFS used by Linux.%BR%Mount it from the binary yourself by doing:<verbatim>losetup -o 262144 /dev/loop1 FILE
mount -t romfs /dev/loop1 /mnt/XXX</verbatim>
      * linux.bin.gz: Starting at 0x2d5250. Contains [[%ATTACHURL%/AngoraVX435_linux.bin][linux.bin]].
      * khwl.o: Starting at 0x277770. Contains [[%ATTACHURL%/test1.elf][khwl.o]].%BR%This contains a lot of useful references to the hardware.%BR%It seems to me this code is all part of Sigma's SDK.

---+++ minimod
The binary minimod is in the [[http://www.beyondlogic.org/uClinux/bflt.htm][µClinux BFLT]] format.

---++ Updating the firmware
   * The firmware is updated by two methods:
      * Downloading the bin file, and renaming it to 'update.bin' loading it into the root directory of the hard disk of the device. Then, whilst on the device%BR%go into the menu system and navigate to 'System Update' and the device will update.
      * Downloading the bin file, storing it on the hard disk of the device. Then when on the device using the file navigator, navigate to the file and %BR%open it to start the update procedure, the device will do the rest

---++ Bricked Firmware
   * I completely misunderstood something that was discussed on IRC, and tried to corrupt the rom, I thought it was meant that I had to turn the device %BR%off mid-firmware upgrade, then see if the device had a fail-safe bootloader if the firmware didn't load as it should. this has turned out not%BR% to be the case, and now the device turns on, but all that happens is the disk starts spinning. so hopefully there's something%BR% I can do to get it working again


---++ Other information

   * The Aigo e235 and the VX435 are basically the same.%BR% Model differences:
      * The Aigo has a 40GB, 60GB, 80GB, 100GB, 120GB or 160GB HDD
      * The VX435 has a 40GB, 60GB, 80GB, 100GB or 120GB HDD
