signatures mismatch on EVLINK firmware upgrade

[fsarmento]

Hi,

Why am I not able to upgrade some EVLink chargers from version 3.4.0.1 or 3.4.0.6 to the latest 3.4.0.10?

I get the error KO, signatures mismatch:

Hello @fsarmento 
Here I suggest to do a B2F and try again to update.
Please make sure your charging station is at least in 3.4.0.1 (R8 run 1) before updating to 3.4.0.10 (R8 run 10)
if it is not the case, please first update in 3.4.0.1
