I want to flash a new firmware to my TP-LINK TL-WR841N router version 14.1. So I have tried to install firmware from DD-WRT. I have tried all other versions available here as version 14 is not available in the dd wrt website. When I try to upgrade firmware from webui I am getting an error 4503 The uploaded file was not accepted by the device. Why this error is getting? Router has 4 MB flash memory, 32MB RAM and Ralink APSoC. I have serial console access as well. Could you please suggest any other method to reflash my router firmware. Any help is highly appreciated.

From you can see that v13 is not supported and v14 is not here .
And if you look at betas version of ddwrt , you can not find v14 ( Jun 15 2020 ) .
On OPEN-WRT, you can see that from , it seems that v14 is only supported in dev/snapshot version . This router is very cheap, and he has only 4MB of flash disk .
This is not anymore recommended for openwrt

You need to use magebuilder to build a very small firmware you can find some advices here
