BACKUP YOUR STOCK FIRMWARE:
- Put openwrt-*-initramfs-uImage.itb to your
TFTP server and rename it to initramfs.bin
- Enable serial console and enter to u-boot cli
and exec these commands:
```
tftpboot <your_tftp_server_ip>:initramfs.bin
bootm
```
- Once boot completed and you get the openwrt shell
execute below commands:
```
device=ax850
mkdir -p /tmp/fw_backup; cd /tmp/fw_backup
rootfs=$(cat /proc/mtd | grep \"rootfs\" | cut -d: -f1)
rootfs_1=$(cat /proc/mtd | grep \"rootfs_1\" | cut -d: -f1)
dd if=/dev/${rootfs} of=rootfs_${rootfs} bs=1M
dd if=/dev/${rootfs_1} of=rootfs_1_${rootfs_1} bs=1M
cp /sys/firmware/fdt fdt.dtb
md5sum * > md5sum
tar -cvzf /tmp/${device}.tar.gz .
sum=$(md5sum /tmp/${device}.tar.gz | cut -d' ' -f1)
mv /tmp/${device}.tar.gz /tmp/${device}_${sum}.tar.gz
echo "stock fw backup saved to: /tmp/${device}_${sum}.tar.gz"
```
- Upload/save your backup to a safe place.
STOCK FIRMWARE RECOVERY:
- Boot initramfs image
- Upload your backed-up stock fw tarball to the device
using scp or download it from the device using wget.
- Enter device ssh cli or tty and exec:
```
cd /tmp && wget <your_web_server_ip>/${stock_fw_backup}.tar.gz`
tar -xpzf ${stock_fw_backup}.tar.gz
rootfs=$(cat /proc/mtd | grep \"rootfs\" | cut -d: -f1)
rootfs_1=$(cat /proc/mtd | grep \"rootfs_1\" | cut -d: -f1)
ubiformat /dev/${rootfs} -y -f /tmp/rootfs_${rootfs}
ubiformat /dev/${rootfs_1} -y -f /tmp/rootfs_1_${rootfs_1}
reboot
```
INSTALLATION:
1. initramfs method
- Put openwrt-*-initramfs-uImage.itb to your
TFTP server and rename it to initramfs.bin
- Enable serial console and enter to u-boot cli
and exec these commands:
```
tftpboot <your_tftp_server_ip>:initramfs.bin
bootm
```
- Once boot completed and you get the openwrt shell
execute below commands:
```
cd /tmp && wget <your_web_server_ip>/factory.ubi`
export rootfs=$(cat /proc/mtd | grep rootfs | cut -d: -f1)
export rootfs_1=$(cat /proc/mtd | grep rootfs_1 | cut -d: -f1)
ubiformat /dev/${rootfs} -y -f factory.ubi
ubiformat /dev/${rootfs_1} -y -f factory.ubi
reboot
```
2. u-boot factory.ubi image method
- Put factory.ubi to your TFTP server and
enter u-boot cli and exec these commands:
```
tftpboot <your_tftp_server_ip>:factory.ubi
#After downloading is finished:
flash rootfs
flash rootfs_1
reset
```
