Hi Everyone,
I am trying to re-flash(not Upgrade) OpenWrt via LuCI WebGUI but i am getting The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform. How can i fix this error ?. Should i follow this Guide. I would like to get the .trx file from openwrt instead of converting,to be on the safe side after all i only have one router.
Thank you.

Given your issue is a rejection of a specific file..... you kind of need to tell is where you got that file from.
C20v?
You need to use the Firmware OpenWrt Upgrade URL: for your device if openwrt is aleady installed even if you are flashing the same release.
Look in the device tech data for your device for the correct firmware

Would that get rid of all the packages that i have installed ?. If so then ill try but that upgrade file is the same format would it work ?
If you just want to reset to default settings just use LUCI and go to
System->Backup Flash/Fimware
Then select Perform Reset under Restore Section
My main reason is that i have installed packages that i dont want now when i uninstall no space frees up. So a re-flash should the trick next time ill have to be careful while installing packages i already backed up configs so no worries there.
perform reset from Luci will achieve your goal.

Luci Perform reset is equivalent to soft reset
