Model: TL-WPA4220 KIT  
Hardware Version:
Firmware Version:

Hi everyone

 

Like many of us, older version of .nvm firmware generated frequent dropouts. Recently I came across an article which recommends updating of the .nvm firmware for WPA4220 and PA4010. I cannot update the firmware for WPA4220 because there is only the option to upload a .bin file on the web interface. I remembered that the older version of the web interface with the firmware that the kit came with allowed flashing of .nvm and .pib files but the latest versions don't. 

 

I then tried to find an earlier version of the .bin type firmware but downgrading is no longer allowed.

 

The question is, how can I bypass the restriction to forbid downgrading? It would be even better if I could just flash the .nvm file invidivually.

 

many thanks

Hello @Moonsie ,

Have you tried to update firmware via the utility: How to update the firmware using the tpPLC Utility on Windows?

When I use the plc stat command, I see that this is the firmware I have: MAC-QCA7420-1.4.0.20-00-20171027-CS

Hi,

 

If you are really serious about updating the Qualcomm firmware of your WPA4220, then you could try it this way: https://community.tp-link.com/us/home/forum/topic/204238?replyId=542774

 

But please acknowledge that there is a chance you might brick your WPA4220 in the process.

  @woozle Thank you for your reply.

 

Indeed I did try this. I could successfully update my PA-4010 but it is not working for WPA4220. This is the error I am getting:

"No NVM Softloader Present in Flash Memory (0x71): Device refused request"

 

Would anyone here have a flash dump so that I can try updating the flash through a physically connection ?
