Simpletech Simpleshare

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.
DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details.

1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.
This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.

2) OpenWrt support for this device has ended in 2022.
19.07.10 was the last official build for 4/32 devices.

Install OpenWrt (generic explanation)

  • Modified Simpleshare Firmware 1.07 With Telnet Enabled here
  1. Flash the SimpleShare with any version of the original firmware that has telnet enabled. (1.07 and 1.09 tested)
  2. Enable telnet
  3. Turn on boot_wait in the nvram
    nvram set boot_wait=on
    nvram set wait_time=5
    nvram commit
  4. Unplug the power to the Simpleshare
  5. Upgrade the SimpleShare using Tftp. From Linux do the following command
    arping -f ip_address;atftp -p -l openwrt-brcm-47xx-squashfs.trx ip_address

    then plug in the power to the simpleshare

  6. Wait for at least 5 minutes before rebooting or unpluging.

You will want to include the following packages in your build of OpenWrt.

  • kmod-ide
  • kmod-fs-ext3
  • kmod-block
  • kmod-block-mount
  • kmod-block-ext
  • fdisk
  • mk2fs
  • backfirer23044 and trunk r23043 patches that enabled the 'failsafe' feature. The reset button as you know is hardwired and wont work to enter failsafe mode. To enter failsafe unplug device, plug back in, once the blue light comes on press the power button a few times, this will trigger failsafe mode.
  • r27005 - This patch fixes nvram overwriting issues. Ive fixed the offset for the nvram to the proper location. Now places the backup nvram into a partition 'nvram_copy'
