Installation via stock firmware
1. Unlock Telnet access by downloading the backup .tar.gz file
2. Change the Telnet configuration to LAN_Telnet=1
3. Import backup configuration
4. Restart the router
5. Login to telnet with username and password = admin : db40
6. Download sysupgrade binary and mtd_write to the kernel partition
`mtd_write write openwrt-bolt_bl100-squashfs-sysupgrade.bin Kernel`
