This how-to describes the method for performing OpenWrt file-level backup/restore. Follow Preserving configuration to determine whether to keep the settings. Follow Firmware upgrade to identify manually installed packages. Follow Generic backup for block-level backup/restore. Goals. Provide an easy way to restore OpenWrt to the previous configuration state. Web interface. 1. Customize and ...

Layer2: we subdivide mtd5 (firmware) into mtd1 (kernel) and mtd2 (rootfs); In the generation process of the firmware (see imagebuilder) the Kernel binary file is first packed with LZMA, then the obtained file is packed with gzip and then this file will be written onto the raw flash (mtd1) without being part of any filesystem! During boot, u-boot copies this entire section into RAM and executes it. From there on, …

Navigate to LuCI → System → Backup / Flash Firmware → Actions: Flash new firmware image. Click Choose File button to select firmware image. Click Flash image… to upload firmware image. Verify firmware image checksum and proceed.

Since OpenWrt does not write to those partitions, it is very unlikely that they get corrupted by OpenWrt itself. However, if you mess around with the bootloader, you certainly should create a copy of this data on your PC. Otherwise, in case you lose that data, you would have to go to the forum, ask somebody to make a backup of his and send it to you, then you would have to replace the MAC ...

The Image Generator you download from the OpenWrt pages is already configured to download any non-default packages from official repositories. The package sources are configured in the repositories.conf file in the extracted directory. Sources are specified in opkg native config format. This can be either the official package repositories or custom generated repositories.

Note:: It is possible to contain the entire root filesystem on a JFFS2-Partition only, instead of a combination of both. The advantage is that changes to included files no longer leaves behind an old copy on the read only filesystem. So you could end up saving space. The disadvantage of this would be, that you have no failsafe any longer and also, JFFS2 takes significantly more space then ...

 · I am looking to try to extract the filesystem using binwalk/firmware-mod-kit, although I am having troubles with my current dump of the flash. Binwalk/FMK detects everything and it seems to extract the data after decompressing the image, but it leaves me with two IMG files of file system type JFFS2 which I can't seem to mount. Usually binwalk ...

 · Glad I came across this webpage. I have Netgear WNR2000v4 (ar71xx) router converted to OpenWRT with the same problem of no space remaining to install openvpn packages. I would highly appreciate if you can help me with removing all ipv6 packages from LEDE 17.01.6 firmware or Openwrt 18.06.1 tiny firmware so that I can install Openvpn on it.

combined-squashfs.img.gz This disk image uses the traditional OpenWrt layout, a squashfs read-only root filesystem and a read-write partition where settings and packages you install are stored. Due to how this image is assembled, you will have only 230-ish MB of space to store additional packages and configuration, and Extroot does not work.
