step for update firmware dir-615 e4 to dd-wrt v24sp2
Basically, what you need to do is to check what is the hardwareID of the
E4. How to do it is by looking at the original D-Link firmware from the
D-Link Taiwan website (only the D-Link Taiwan website has the E4
firmware at the moment). Download and open the original D-Link firmware
(download links are below) and open it using a HEX editor (i use ghex2).
Scroll down all the way to the bottom of the file and you will see the
hardwareID (it should read AP99-AR7240-RT-091105-01). Now, compare the
hardwareID of the original D-Link firmware (DIR615E3_E4_FW510B09.bin)
with the DD-WRT firmware (dir615e4-factory-to-ddwrt-firmware.bin). Edit
the DD-WRT firmware to have the same hardwareID of the original D-Link
firmware. For me, i only had to change the last digit from 5 to 1.
ok i edit only "AP99-AR7240-RT-091105-05" to "AP99-AR7240-RT-091105-01"
