Question on flashing

I want to flash: 

DD-WRT for R8500 (Tathagata Release - Revision 28813)

Stock firmware on router now. Do I just flash the .chk file or do I need to also

flash a ,bin file?  If I need to flash both which is first and where do I find the .bin file.

Thank you in advance,

First flash the .chk file,

First flash the .chk file, that allows the router to go to ddwrt from stock, then flash the .bin, making sure that you click the box that says reset to factory defaults so that the NVRAM and other settings that carried over but are not compatable don't stick.


Any other questions about that go ahead and message me again!

you don't ned it just upload

you don't ned it just upload the file from here and do a 30/30/30 reset. when you upload it give the router a few minutes to reset before you do the reset dance.

Anyone have an issue with

Anyone have an issue with going from Kong .26 image for the R8500 and then downgrading to stock Netgear firmware?

Once I downgraded back to stock, the default username/password (admin/password) for Netgear no longer works.  I even tried the default root/admin for dd-wrt and I can't get that too work.  I even tried my old password and it won't work.  I have factory reset it 3 times now and still no go.  I also have a problem with the router no longer supporting dhcp and I had to statically configure it with a address and subnet mask.

@  litespeeder had you clear the history of your browser? after that try with default username and password.

Hope it will works.
