Two bulbs will not update firmware...

Hello!

Just bought two Color bulbs. Unfortunately, even after resetting a few times, using two different phones and trying to use them, Updating is stuck at 100% for a while and then it says it failed.

Current fw is 1.4.1_48, and they want to update to 1.4.2_0070. Tried both with my router (network is excellent) and through a mobile hotspot, but nothing.

Any other steps I could follow?

Thanks!
