My upgrade appeared to work perfectly fine... Flashed amber while upgrading, then went solid green... Powered off vision, removed card to verify .bak file was present... The file did get successfully renamed... I then removed the file... Placed card (original micro SD) back into camera, powered on vision, got constant flashing amber... Tried again and again... No luck...
When 1.1.8 was released a few weeks ago, I upgraded without a hitch... Same way of course...
I contacted DJI in China because no one answers the US line... Call was immediately answered... I explained what I did and what happened... I even asked about the "factory reset" that's mentioned... I was told that I need to return the camera to the dealer where I purchased for a replacement... He said that a factory reset can only be done there at DJI...
I initiated an RMA with B&H (again)... I did this over the phone and the rep said that they have had "many" of these problems the last two days... They said send the ENTIRE unit back, not just camera... They also upgraded my replacement shipping to Next Day Air... B&H seems to be really good at handling things, just wish it didn't take so long to complete the process...
This problem is so strange... There's many that DONT have the issue and then there's those who do... It's really kinda hard to screw up the upgrade... Use the original card, copy the firmware.bin file to root, place in vision, power on... Once it turns solid green, power off, remove card, verify bak file was created and then remove it, place card back in vision and power on...
The only thing I did NOT do was format the card immediately prior to putting the bin file on it using the app... I didn't do this because the card was previously formatted using the app... I just placed the file on the card... This is way too strange...
