Firmware version needs correction (D7800, compatibility warning)

Installing and Using OpenWrt
21

hi. heres exactly what i'm doing...

1- back of d7800 router is the 'reset' hole...
--- hold it for ~20 seconds and go to https://192.168.1.1 afterwards; now in recovery mode.

--- in luci admin, click on link for upgrading firmware.

..... purpose was to clear any potential malware, upload newest openwrt image.
--- but trying to do that led to the V1 vs V2 problem.

...no tftp involved in any way.

... no old backups, always fresh download install.

... later today i will ssh in & see what i find in the /etc/cofig/system file.

thx

If you end up in LuCI, you are not in any recovery mode. But in normal OpenWrt.

What I mean with "recovery mode", is the OEM TFTP recovery mode...

Ps. The simplest solution for you might be to reset the router from LuCI (and not restore settings afterward). That should reset also the compatibility setting.

Trying to reset from Luci not possible as 'image check fails' pops up first b/f anything about 'keeping settings'...if thats what you meant.

No, you'd click "Perform Reset" and inform us of your results and agree to erase all settings.

I ssh'd in and tried to open /etc/config/system, but file was not there or empty.

I used following command:

" # echo -e "config system\n\toption hostname 'Openwrt'\n\toption timezone 'GMT-4'\n\toption compat_version '2.0'" > /etc/config/system

Dont remember if i had to add following or it had it in there by default...

config system
option hostname 'Openwrt'
option timezone 'GMT-4'
option compat_version '2.0'

worked.

thanks!
