R6300v2 firmware not updating from V1.0.3.6_1.0.63CH

I post the following for those who stumble upon this thread in the future and wonder what the eventual solution was.

By cobbling together the steps below from various sites, threads, suggestions and then modifying it for current conditions.

This worked for me and left me right where I wanted to be .

I used the following procedure specifically to remove the CH (charter) version and revert back to V1.0.3.22_10.0.67 – same version, but no longer Charter. From this I could then upgrade to the latest version from Netgear. If you’re looking to do something different you will need to modify these instructions for your purposes. Again, this worked for me, but may not for you for any number of reasons. Good luck.

1. Manually Backup your router settings - write them down

2. Flash the new firmware dd-wrt.K3_R6300V2CH.chk (can now be found here https://forum.dd-wrt.com/phpBB2/download.php?id=42538&sid=417bea094969968cd6a3c07c50635a51)

3. This will change the firmware to V1.0.3.22_10.0.67, which is no longer Charter

4. NOTE: The router interface will change drastically. See here for more details on dd-wrt: http://en.wikipedia.org/wiki/DD-WRT

5. You will need to navigate to flash the new updated firmware; On the Administration tab there is a FirmWare Upgrde tab

6. Flash the new firmware with the latest version from Netgear – currently R6300v2-V1.0.4.36_10.0.93

6. Wait till the router is fully flashed and restarted.

7. Factory reset your router.
