Huawei B593u-12

The Huawei B593u-12 is a router with an integrated LTE modem. It is also sold as branded versions by telco providers, e.g. as Telekom Speedport LTE II and as Vodafone B2000.

Devices with Broadcom WiFi chipsets have limited OpenWrt supportability (due to limited FLOSS driver availability for Broadcom chips). Consider this when chosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported. See Broadcom WiFi for details.

Supported Versions

This router is currently not officially supported by OpenWrt, but it can boot OpenWrt through a serial console.

LTE, NAND and USB are working. NAND gets detected as a “USB Mass Storage device”, and from factory it is formatted ext3.

You can flash the router through CPE or through the web page from the factory image. However, when OpenWrt boots it does not manage to write to the flash.

LAN and switch were working with target profile brcmsmac in Kernel 4.9. With Kernel 4.14 and subsequent versions, a bug prevents the switch from coming up. The last commit before removal of Kernel 4.9 support in brcm47xx is b7dd438f66253cc49fa8b0b3434d5ef50fffbb7c.

WLAN is not working due to missing drivers.

Flash Layout

The flash layout from the factory firmware is:

Huawei B593u-12 Flash Layout
Layer0 raw NOR flash memory chip (M25FL128 serial flash (size: 16.384KiB, blocksize: 0x40000 (256KiB), blocks: 64)
Layer1 Bootloader 256KiB mtd2: rootfs 10.240KiB Subject image 3.750KiB Current Config 256KiB Factory Config 256KiB Temporary Config 512KiB Fixed Config 256KiB Log Config 256KiB mtd1: auxfs TR-069 certificate 256KiB mtd0: nvram 256KiB

From the factory image, “B593.trx” gets flashed into mtd2: roots. The rescue image “B593-small.trx” gets flashed into the Subject image. Current and Factory Config store the configuration as plain text XML (with the initial 4 Bytes being the length of the configuration). The remaining partitions (except mtd0: nvram) are mostly filled with “FF”, so it is unclear if they are empty, or if the dump didn't succeed.

The flash layout that OpenWrt recognizes is:

The factoy image doesn't recognize all of the flash in Linux. However, the proprietary tool “flashtest” gives insights into the flash, and allows dumping it, e.g. you can dump all of the flash with command “flashtest export 000000 16777216”. Here is a comparison of what “flashtest”, “dmsg” and “/proc/mtd” provide.

Gaining root access to original Firmware

Many firmware versions allow enabling Telnet, and thus opening a shell with root access.

Telekom firmware

For firmware versions V100R001C748SP106 and V100R001C748SP107, you can modify the original firmware before flashing it to disable the firewall rules that block the Telnet Server. There is link a the end to of the page to the source of this information.

Step 1: Install the required tools on your computer

sudo apt-get update
sudo apt-get -y install git build-essential zlib1g-dev liblzma-dev python-magic zip unzip

mkdir -p ~/fmk
cd ~/fmk
git clone https://code.google.com/p/firmware-mod-kit/
cd firmware-mod-kit/src
./configure
make

Step 2: Download and unpack the firmware

mkdir -p ~/fmk/107
cd ~/fmk/107
# Download Firmware_Speedport_LTE_II_B593u-12_V100R001C748SP107.zip -- unfortunately, Telekom doesn't host this file anymore
unzip Firmware_Speedport_LTE_II_B593u-12_V100R001C748SP107.zip
tar xvf V100R001C748SP107.tar.bz2 

Step 3: Unpack, modify firmware to allow inbound telnet from LAN, then repack firmware

# Extract the trx file
~/fmk/firmware-mod-kit/extract-firmware.sh B593.trx 

# Make a backup of the file we are going to patch
cp -a fmk/rootfs/bin/cms fmk

# Allow inbound telnet from LAN, make sure your replacement string is exactly same length as the original!
sed fmk/rootfs/bin/cms -i \
    -e's|iptables -A INPUT_SERVICE -p tcp  --dport 23 -j DROP 2>/dev/null|iptables -I INPUT -s 192.168.1.0/24 -j ACCEPT ##################|g'

# Check that original and modified binaries are same size but have different timestamps
ls -l fmk/cms fmk/rootfs/bin/cms

# Remove some unnecessary files to shrink squashfs image and keep fmk happy
rm -f fmk/rootfs/sbin/mkntfs

# Update version string in headers so device already running SP107 will accept our customized version
sed -i.bak fmk/image_parts/header.img \
    -e's|V100R001C748SP107\x00\x00\x00|V100R001C748SP107hax|g'

# Rebuild the trx file
~/fmk/firmware-mod-kit/build-firmware.sh

# Create the new firmware archive
mv fmk/new-firmware.bin B593.trx
chmod 0644 B593.trx modem.bin help.tar.bz2 B593-small.trx
tar --owner=LTECPE --group=LTECPE -cvjf V100R001C748SP107_TELNET.tar.bz2 B593.trx modem.bin help.tar.bz2 B593-small.trx

# Clean up
sudo rm -rf fmk

After upgrading your router with the new firmware it should be reacheable over telnet. Telnet takes some time to start, so if the connection is refused try a few moments later. You can login as “admin” with password “HW4GCPE”. This takes you the ATP prompt, where you can type the undocumented command “shell” to open the root shell. Documented commands are: cls, debug, help, save, ?, exit.

TTL Serial Console

The pins to the TTL serial console are shown in the pictures at the begining of this article. The settings are 115200 8N1. With the factory settings, the console is disabled for both CFE boot loader as well as for Linux. So you need to enable it in the NVRAM. The easyest way of changing the NVRAM is through Telnet root access, as described above.

The following commands enable the console for CFE and Linux, and enable a 10 second delay and additional recovery options during boot:

nvram set console_disable=0
nvram set boot_wait=on
nvram set wait_time=10
nvram commit

If you don't have root access, you can put your device into recovery mode:

  • Press and hold down all three buttons on the side (WLAN, RESET, WPS)
  • Turn power on and keep pressing all buttons
  • All LEDs will turn on
  • Release buttons when all LEDs except POWER turn off

If your cabling is correct, you will see the Linux boot log messages, and the WPS LED will start blinking. In the root shell you can update the NVRAM as described above. The login for the serial console is the same as for Telnet, i.e. “admin” and “HW4GCPE”.

Press CTRL+C during initial seconds of boot to get into CFE console and load your own firmware.

While in recovery mode, you can also send commands to CFE through the web interface. For instance, to call “show clocks” enter into the webbroser http://192.168.1.1/do.htm?cmd=show+clocks. The ouput will only be shown on TTL, but you can use this to update NVRAM or boor an ELF image.

Command in CFE are:

et                  Broadcom Ethernet utility.
show clocks         Show current values of the clocks.
nvram               NVRAM utility.
reboot              Reboot.
flash               Update a flash memory device
batch               Load a batch file into memory and execute it
go                  Verify and boot OS image.
boot                Load an executable file into memory and execute it
load                Load an executable file into memory without executing it
save                Save a region of memory to a remote file via TFTP
ping                Ping a remote IP host.
arp                 Display or modify the ARP Table
ifconfig            Configure the Ethernet interface
help                Obtain help for CFE commands

Booting OpenWrt

You need to build your own image:

git clone https://git.openwrt.org/openwrt/openwrt.git
cd openwrt

// In case you want working Ethernet
git checkout b7dd438f66253cc49fa8b0b3434d5ef50fffbb7c
// Change "KERNEL_PATCHVER" to 4.9
vi target/linux/brcm47xx/Makefile

// The image Makefiles need to be adapted regarding two issues:
//   The lzma-loader crashes, maybe due to a watchdog reset during kernel decompress? But KERNEL_NAME = vmlinux-nodictionary.lzma without a loader will work.
//   You need an additional 256Bytes header after the TRX header. Will commit both changes as soon everything else is done.

// At first boot, OpenWrt will try to fix the CRC in the TRX. This corrupts the flash due to additional header. So please comment it out
vi target/linux/brcm47xx/base-files/etc/uci-defaults/09_fix_crc

./scripts/feeds update -a
./scripts/feeds install -a

make menuconfig
make

    • USB
      • Add usb2
      • For LTE support add usb-net-cdc-ether, kmod-usb-net-cdc-mbim, usb-net-huawei-cdc-ncm, usb-net-qmi-wwan, usb-serial, usb-serial-option, usb-serial-pl2303
      • For NAND support add usb-storage and usb-storage-uas (and fs-ext4 from Filesystems)
    • Other: Even though this router has a PCA9555 GPIO controler which is supported by kmod-gpio-pca953x, adding this kmod doesn't seem to have any impact, and there are do changes in “dmesg” or “cat /sys/kernel/debug/gpio”
  • Remove anything else that is not needed if you image is too large, e.g. in Base: ca-bundle, dropbear, opkg, otrx, openwrt-keyring, ppp, usign
  • The ramdisk will not include any modules, so add everything you need into the kernel

You will find “vmlinux-initramfs.elf” in “openwrt\build_dir\target-mipsel_74kc_musl\linux-bcm47xx_mips74k”. Please note that the file needs to be less than around 6.850KB (tests show that 6.852KB will be too large to boot, but 6.847KB will work).

Connect your computer to the LAN of the router. You should get an IP via DHCP, else pick an IP, e.g. 192.168.1.2. Start a TFTP Server on your computer. (dont forget to turn off the firewall). On the CFE console type

boot -elf -tftp 192.168.1.2:vmlinux-initramfs.elf

A bad flash might reset your NVRAM and then you loose the console, so you need to redo the procedure above.

Restoring Factory Firmware

If you end up corrupting your flash and your router cannot boot (e.g. with the error “Invalid boot block on disk”), then the router will expose the “Broadcom - CFE miniWeb Server” on http://192.168.1.1, in which you can upload B593.trx from the factory firmware file, e.g. V100R001C748SP107.tar.bz2.

You can also access the miniWeb Server in the recovery mode, see above on how to enable that.

The router also saves a rescue image (from firmware file B593-small.trx) on flash. The easiest way of returning this and other parts of flash to the original state is flashing the bz2 file from the vendor trough the factory image. To do so, restore B593.trx as described above, log in via TTL pr Telnet, connect a USB drive with the factory firmare, e.g. V100R001C748SP107.tar.bz2, and then run upg -f V100R001C748SP107.tar.bz2.

Be very carefull when flashing through CFE, as it is possible to overwrite the boot partition, bricking your router. Is seems that it is also possible overwrite Ethernet or Wifi firmwares, thus making the router loose all connecting in factory firmware. Unfortunately, the command “show devices” is not availble. The following partitions are confirmed to exist: flash0, flash0.boot, flash0.trx, flash0.trx1, flash0.os, flash0.os1, flash0.nvram, flash1.boot, flash1.para, flash1.trx, flash1.trx1, flash1.nvram.
