Hi, I am also having the same problem as some users here. I can't update my desklamp either. It is currently on firmware 1.2.6_22 and I am attempting to upgrade to version 1.2.9_47. I have tried with both the MIJIA app as well as the Yeelight app on both iOS and Android and they were both unsuccessful. MIJIA App pauses at the 30% mark but goes all the way to the "Installing" process but gets stuck there forever, while the Yeelight stops at 30% and gets stuck there forever. If I close the app and restart it, the whole process will start from the beginning again.
Any ideas on how to fix this issue? I have updated the firmware in the past before with no problems (I am still at the same location with the same internet provider). Please help, I would really like to update my firmware. Thanks for all your help.
