hello

i am in desprate help

i have 6 deco m5 in my home, 3 i purchased from Dubai and 3 from Egypt

the system was running perfectly until yesterday when i updated the main deco from v 1.5.7 to the new firmware 1.6.0

all the 3 decos from Dubai updated to 1.6.0 but not the 3 from egypt using anthore firmware 1.5.6 Build 20210630 Rel. 83844 apparently the update is not available yet.

after, some of my home devices failed to connect and other keep connecting and disconnecting

i tried switching the main deco to one running 1.5.6 but still as if there are conflicts in between

i wish i can revert to 1.5.7 again

is threre a way?

thanks
