Flash instruction using initramfs image:
1. Prepare TFTP server with IP address 192.168.11.10
2. Rename OpenWrt initramfs image to "WXR-5950AX12-initramfs.uImage and
place it to TFTP directory
3. Hold AOSS (WPS) button and power on WXR-5950AX12
4. WXR-5950AX12 downloads initramfs image from TFTP server and boots
with it automatically
5. Upload sysupgrade image to WXR-5950AX12 and perform sysupgrade
6. Wait ~120 seconds to complete flashing

Notes:
- WXR-5950AX12 has 2x OS images on NAND flash. The 1st image is for
normal operation and the 2nd one is for recoverying or firmware
upgrading on stock.
- Stock U-Boot checks MD5 hashes in "fw_hash" volume in each "root*"
partition when booting. This is just a comparation of hash strings.
Behaviors:
- both "fw_hash" volumes exist, hashes are rootfs == rootfs_recover
---> boot from rootfs
- both "fw_hash" volumes exist, hashes are rootfs != rootfs_recover
---> boot from rootfs_recover
Note: this behavior is used for firmware upgrading on stock
- "fw_hash" volume in rootfs is missing
---> boot from rootfs_recover
- "fw_hash" volume in rootfs_recover is missing
---> boot from rootfs
- "fw_hash" volumes in both root* partition are missing
---> boot from rootfs_recover
Reverting to stock firmware:
1. Decrypt official image by buffalo-enc and remove header
example of decryption:
$ buffalo-enc -i wxr_5950ax12_jp_305 -o wxr_5950ax12_jp_305.dec \
-d -k olaffuB -O 0xc8
example of removing header (v3.05):
- before
$ hexdump -n 64 -v -C wxr_5950ax12_jp_305.dec

- after
$ hexdump -n 64 -v -C wxr_5950ax12_jp_305.ubi
00000000 55 42 49 23 01 00 00 00 00 00 00 00 00 00 00 00 |UBI#............|

2. Boot WXR-5950AX12 with OpenWrt initramfs image
3. Upload modified stock image to WXR-5950AX12
4. Find partitions "rootfs" and "rootfs_recover"
example:
root@OpenWrt:/# cat /proc/mtd
dev: size erasesize name
...
mtd22: 04000000 00020000 "rootfs"
mtd23: 04000000 00020000 "rootfs_recover"
...
in this case, "rootfs" is mtd22 and "rootfs_recover" is mtd23
5. Format "rootfs"/"rootfs_recover" partition with the uploaded image
example:
ubiformat /dev/mtd22 -f /tmp/wxr_5950ax12_jp_305.ubi
ubiformat /dev/mtd23 -f /tmp/wxr_5950ax12_jp_305.ubi
6. Remove "rootfs"/"rootfs_data" volume from user_property partition
example:
. /lib/upgrade/nand.sh
UBI=$(nand_attach_ubi user_property)
ubirmvol /dev/$UBI -N rootfs
ubirmvol /dev/$UBI -N rootfs_data
7. Reboot
