Installation
OpenWrt installation
1. Login to the router web interface under admin account
2. Navigate to Settings → Configuration → Save to Computer
3. Decode the configuration. For example, using cfgtool.py tool (A tool for decoding and encoding Sercomm configs - https://github.com/r3d5ky/sercomm_cfg_unpacker):
cfgtool.py -u configurationBackup.cfg
4. Open configurationBackup.xml and find the following line:
<PARAMETER name="Password" type="string" value="<your router serial is here>" writable="1" encryption="1" password="1"/>
5. Insert the following line after and save:
<PARAMETER name="Enable" type="boolean" value="1" writable="1" encryption="0"/>
6. Encode the configuration. For example, using cfgtool.py tool:
cfgtool.py -p configurationBackup.xml
7. Upload the changed configuration (configurationBackup_changed.cfg) to the router
8. Login to the router web interface (SuperUser:ETxxxxxxxxxx, where ETxxxxxxxxxx is the serial number from the backplate label)
9. Navigate to Settings → Access Control → Allow SSH (& Press apply)
10. Connect to the router using SSH shell under SuperUser account
11. Run in SSH shell:
sh
12. Make a mtd backup (optional, see related section)
13. Change bootflag to Sercomm1 and reboot:
printf 1 | dd bs=1 seek=7 count=1 of=/dev/mtdblock3 reboot
14. Login to the router web interface under admin account
15. Remove dots from the OpenWrt factory image filename
16. Update firmware via web using OpenWrt factory image
Backup
It's recommended to make a mtd backup before you start:
1. Set up a tftp server (e.g. tftpd64 for windows)
2. Connect to a router using SSH shell and run the following commands:
cd /tmp for i in 0 1 2 3 4 5 6 7 8 9 10; do nanddump -f mtd$i /dev/mtd$i; \ tftp -l mtd$i -p 10.0.0.2; md5sum mtd$i >> mtd.md5; rm mtd$i; done tftp -l mtd.md5 -p 10.0.0.2
Return to Stock
1. Change the bootflag to Sercomm1 in OpenWrt CLI and then reboot:
printf 1 | dd bs=1 seek=7 count=1 of=/dev/mtdblock3
2. Optional: Update with any stock (Etisalat S3) firmware if you want to overwrite OpenWrt in Slot 0 completely.

Upgrading OpenWrt
LuCI Web Upgrade Process
- Browse to
http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/
LuCI Upgrade URL - Upload image file for sysupgrade to LuCI
- Wait for reboot
Terminal Upgrade Process
If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There is a command line method for upgrading:
sysupgrade
Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
sysupgrade
- Login as root via SSH on 192.168.1.1, copy images to /tmp using SCP and then enter the following commands:
cd /tmp sysupgrade /tmp/sysupgrade.bin
Debricking
sercomm-recovery utility
1. Compile sercomm-recovery under the Linux:
git clone https://github.com/danitool/sercomm-recovery.git make
2. Connect the router with a cable and run sercomm-recovery:
sudo ./sercomm-recovery enp0s3 recovery_etisalat_s3_stock_slot1.bin
where enp0s3 - network interface connected the router, ifconfig - list on available network interfaces
3. Wait until the router is flashed and rebooted.
Download ready recovery images for Sercomm devices.

Notes
This appears to be the same device as the Vodacom S3, though the firmware on the Vodacom S3 saves an encrypted .rom file instead of a .cfg file and so is not able to be flashed using the same procedure.
