Seagate GoFlexHome

Note: No green led working NIC / data partition (mtd3) does not seem to be 216 MiB(see serial installation wiki (french side) + command df -h)

→ port.serial general information about the serial port, serial port cable, etc.

How to connect to the Serial Port of this specific device:
Serial port

Pinout J1:
8  Rx  (in)
9  Tx  (out)
10 GND (3.3V)

Port:
115200 
8N1

The default network configuration is:

See Crypto Hardware Acceleration

Connect device to Ethernet port. To prevent automatic updates by cloud engines (which may disable ssh access), use a separate switch or disconnect your router from the internet. If the ssh access was disabled by the automatic cloud engine update service, you need to login there and re-activate ssh.

Find IP address, BE and EF are the last two bytes of the MAC of your device (printed on the bottom of the GoFlexHome)

root@host ~ # ifconfig eth0 169.254.1.0 
root@host ~ # nmap -e eth0 -sP $(printf "169.254.%d.%d" 0xbe 0xef)

Connect to IP address via ssh (root / stxadmin) to see if it works.

If you want to restore the original firmware at a later point use this guide to make a backup. You need to login to the original firmware via ssh first. Another method beside using “dd” is nanddump. To be on the safe side, you should take a 2nd backup with the nanddump method. Assuming you have a USB Stick or other USB drive mapped via sda - you can try this:

cd /tmp
mkdir backup
mount /dev/sda1 /tmp/backup
wget http://plugapps.com/os/pogoplug/uboot/nanddump
chmod +x nanddump
./nanddump -nf backup/mtd0 /dev/mtd0
./nanddump -nf backup/mtd1 /dev/mtd1
./nanddump -nf backup/mtd2 /dev/mtd2
umount /dev/sda1

Prepare on PC

Download files (change the 18.06.2 in the following link into whatever is the last OpenWrt release) https://downloads.openwrt.org/releases/18.06.2/targets/kirkwood/generic/u-boot-goflexhome/u-boot.kwb

https://downloads.openwrt.org/releases/18.06.2/targets/kirkwood/generic/openwrt-18.06.2-kirkwood-seagate_goflexhome-squashfs-factory.bin

Start tftp-server

sudo dnsmasq -p0 --enable-tftp --tftp-root="/tmp" -d

Copy files u-boot.kwb, openwrt-18.06.2-kirkwood-seagate_goflexhome-squashfs-factory.bin to /tmp

Install u-boot

Hit any key to stop autoboot in the u-boot and set goflexhome ip, tftp-server ip, set your mac-address from bottom of the machine:

setenv ipaddr '192.168.1.1'
setenv serverip '192.168.1.2'
setenv ethaddr '00:10:75:xx:xx:xx'
saveenv

download from tftp-server u-boot.kwb file to RAM start offset 0x6400000

tftp 0x6400000 u-boot.kwb

or

tftpboot 0x6400000 u-boot.kwb

Bytes transferred = 607044 (94344 hex)

erase nand start from 0x0 size 0x100000

nand erase 0x0 0x100000

write nand from RAM start offset 0x6400000 to nand start 0x0 size 0x100000 (1MB)

nand write 0x6400000 0x0 0x100000

reboot device

reset

now you are rebooting in the new u-boot

Install OpenWrt

Hit any key to stop autoboot in the u-boot and set goflexhome ip, tftp-server ip, set your mac-address from bottom of the machine:

setenv ipaddr '192.168.1.1'
setenv serverip '192.168.1.2'
setenv ethaddr '00:10:75:xx:xx:xx'
saveenv

download from tftp-server file openwrt-18.06.2-kirkwood-seagate_goflexhome-squashfs-factory.bin to RAM start default offset 0x800000

tftpboot openwrt-18.06.2-kirkwood-seagate_goflexhome-squashfs-factory.bin

Load address: 0x800000 ... Bytes transferred = 4063232 (3e0000 hex)

erase nand UBI partition

nand erase.part ubi

write nand from RAM start offset 0x800000 to nand UBI partition size 0x3e0000

nand write 0x800000 ubi 0x600000

reboot device

reset

In version 15.05.01 'sysupgrade' not available for GoFlex Home. Use 'mtd' instead to flash the firmware. Note: This is upgrade instruction from already installed OpenWrt. Also, if you have serial access you can still do the normal installation as above.

• Backup configuration.
• To ssh into the OpenWrt GoFlex Home device.
• Check list mtd devices:

cat /proc/mtd

output:

dev:    size   erasesize  name
mtd0: 00100000 00020000 "u-boot"
mtd1: 00400000 00020000 "kernel"
mtd2: 02000000 00020000 "rootfs"        

• Download last firmware release LEDE 17.01.4 to /tmp:

wget -P /tmp http://downloads.openwrt.org/releases/17.01.4/targets/kirkwood/generic/lede-17.01.4-kirkwood-goflexhome-squashfs-sysupgrade.tar

• Extract files from a tar file to /tmp:

tar -xvf /tmp/lede-17.01.4-kirkwood-goflexhome-squashfs-sysupgrade.tar -C /tmp

• Check extracted files:

ls /tmp/sysupgrade-goflexhome/

output:

CONTROL  kernel   root

• Erase 'kernel':

mtd erase /dev/mtd1

• Write 'kernel':

mtd write /tmp/sysupgrade-goflexhome/kernel /dev/mtd1

• Erase 'rootfs':

mtd erase /dev/mtd2

• Write 'rootfs' with reboot after:

mtd -r write /tmp/sysupgrade-goflexhome/root /dev/mtd2
