Will tp link archer c20 ac750 v5 EU firmware work with v5.8 IN? On the website it says US i think and not IN.
If i try to flash and it doesnt work, can i revert back to stock firmware?
On the site it also says gpl code. Does this mean this device firmware is open source?
Thank you!

Could you take a picture of the label blurring all barcodes and secrets upload here?
And website address which says?
Both on the router box and behind the router, it says:
Model: Archer C20(IN) Ver:5.8
On website there is no option for 5.8. Its probably 5 or 5.80.
Wait, ill go to the admin page, and see if i can find any additional info...

See it is all US version. Verify that MAC address is from label and iw reg set IN ; iw list | less
that wifi powers are reasonable (>=20sBm)
Router admin page, firmware upgrade tab shows this info.
I did not understand you. Can you please explain in simpler terms?

5.80 US from indian site
First upgrade to that exact OEM image you use to create factory image. Small chance OEM firmware pairs bootloader with their software version.
So If i understand you correctly, i have to first:
go to https://openwrt.org/toh/tp-link/archer_c20_v5 and download "oem firmware".
upgrade router firmware with downloaded "oem firmware" from web ui.
download sysupgrade firmware from https://openwrt.org/toh/tp-link/archer_c20_v5 AND v5.8 from tp link.
use the dd and cat command.
then upgrade from web ui.
Is this correct?
Ohh so flash 5.8(which i will use to create openwrt), then after dd and cat, flash the created one?
the only reason for DLing the TP-Link fw in the 1st place, is to extract the boot loader, you don't really need to flash it.

Hey, this is where you need to extract bootloader from OEM files.
So what does this mean?
I am confused, can someone tell me easy steps?
Also frollic said use factory image, but the guide says use sysupgrade image
that's exactly what my post said ?
if you want to play it very safe, then do it.
