Firmware update U3 ext from 4.3.96 to 5.2.11

[FrederikV 0]

Hello,

 

i have an issue updating the Firmware from 4.3.96 to 5.2.11.

The needed intermediate firmware 4.3.97 doesn't show up on my U3 ext.
What shows up is the 5.2.11 file. But when the Firmware is getting checked, I become an error "Firmware can't be verified"

Can you guys help me here?

 

Regards

Frederik

4.3.96 had a bug where it fails to update when there is no network connection to a time server. When the printer can't set the current time it will fail with the verify error.

Do you have a network connection? 

Can you reach the printer from Cura? This is another method for setting the time in the printer.

Well that's good to know. I can connect to the printer, yes. The problem with the time server is know but i didn't care about, because anything worked.

Could you explain how to do it? I found some tread where you have to get into developer mode, but i m not sure its the right way.

 

Thanks alot

Problem solved with the Help of this link/with IT:

Great to hear you were able to solve the time synchronization.

 

The other solution I mentioned is that you use Cura to connect to your printer, then Cura should automatically set the time in the printer. After this you can start a download.

so I managed to get back on the the network. 

am having the same problem. 

 

I connected to cura connect, putty etc.... but it's still stuck in the 1970's 

 

the link isn't self explanatory so is there any one that can provide me a guide how to sort this fiasco out.  

 

cheers

There's another link with instructions in the post from below. The first two steps are probably sufficient to convince the firmware update process ("set date..." and "set time...").

Precondition is, that you're logged in to the printer as root (putty), it seems that you already know this part.

 

The extra validation of date and time should be a thing of the past, once you managed to install version 5.2 (AFAIK). So that should be a one-time effort.

much appreciated for the advice. 

 

I came across a problem late last night.  for some reason it wouldn't connect with the WiFi board.  i tried everything but it wouldn't wouldn't show any activity by means of the green light on the board.  so I couldn't connect over that.  I sort of connected through cable but I wasn't able to use putty to connect.  so I did the MicroSD card reset and managed to get back up an running.  just sooooooo annoying to have this problem in the first place 😞

 

really appreciate the help though.
