successfully upgraded to it, hoping won't have to face these types of issues in future. thanks

@Kevin_Z 

Upgrade was successfull. With the new firmware wireless and wired components are detected. Is this the right behaviour?

With the old 1.4 firmware only the wireless components were detected.

My deco m5 works in ap mode. Two decos were connected with my zyxel switch, two more are wireless connected.

@Kevin_Z Good morning Kevin, I feel that with my knowledge of computer science, I am not able to install the beta version for my M5 system. I would appreciate if possible explain the first steps in detail to do the operation. Thank you very much

@Rioja 

Hi Rioja

you have to update the firmware with the web gui of the deco.

Login to the main deco, go to Advanced, then System. Just click on firmware upgrade

@Kevin_Z 

Hi,

I just dowloaded the 1.4.2 beta firmware and tried to upload it from web UI.

after clicking on Upgrade button, I can see the file transfer at bottom left of browser and finally a chip that says operation succeeded

that said, nothing updates and I can see a 500 error in the browser dev tools  on following url

http://192.168.68.1/cgi-bin/luci/;stok=82d397e2d02335d63ca5485e80f09608/admin/cloud?form=firmware_status

Any idea what's wrong ?

BTW, I have 3 Deco M5 units, hardware V1.0 (EU)

I installed them from app and was only able to update primary one, so right now I have:

main deco : 1.4.0 Build 20191223 Rel. 38921

first slave & secondary slave : 1.1.5 Build 20170820 Rel. 62483

I've never been able to update from mobile app again (says unable to check for updates) nor the web UI online option as in that case even if UI shows all units with correct versions when I click on "check for upgrades", I get a never ending spinner and again in the console I see the following javascript error:

frame.js:1 Uncaught TypeError: Cannot read property 'toString' of null
    at Object.o.su.escapeHtml (frame.js:1)
    at l.su.widgets.<computed>.renderer (eval at <anonymous> (jquery.min.js:3), <anonymous>:1:1299)

Anyone can help?

thanks a lot in advance

@Rioja Good afternoon Kevin, I just updated, beta version 1.4.2 Build 20200116 Ref.46064. Everything works fine, I will report anything that may surprise me.

@Kevin_Z 

So I am hesitate to install  Beta Firmware. Is there any timeframe of when an official release will be? Also when updating this to the 1.4.2 version (should I choose to do so); will this update ALL M5 Deco's & not just the main unit?

@Kevin_Z  plz let us know when will u guys roll out the official firmware, is there any specific time period and would be better be better if u could tell us the exact date.

thanks

@gatito I experienced this the first time as well (there was a new firmware version but the app never showed it so I wanted to install manually). 
 

what worked for me was connecting my laptop wired to one Deco (it wasn't the main Deco but to be safe I recommend you do that) and removing the cable that's between your modem/router and your Deco (so basically disconnect it from the internet).
TP-link had a guide somewhere (can't find it that quick) that actually suggested to try to upgrade the Deco's while disconnected from the internet. That seemed to work for me. 

I hope it works!
