My experience upgrading v2 camera firmware to 4.9.4.37.
4/22/19
Upgraded two (2) cameras last night after seeing new firmware was released for the v2. Both cameras gave me the “Firmware is Up to Date” splash screen when the upgrade progress bar graph was around 75%. So far, both cameras seem to function flawlessly even after a power cycle. The issue with firmware 4.9.4.28 with the cameras continuously restarting on power up with an SD card installed appears, so far, to have been resolved.

Upgraded five (5) cameras this morning.
With the first camera, the upgrade progress bar graph went all the way to 100% and the splash screen displayed “Upgrade Failed”. Checking the firmware version in the Device Info, the firmware was upgraded to 4.9.4.37 and the camera worked fine before and after a power cycle.
With the second camera, all went well with the upgrade, getting the “Firmware is Up to Date” splash screen around 80%. Checking in Device Info, firmware ver. was 4.9.4.37. After the firmware was upgraded, could not connect to the camera. So exited the Wyze app on my Android tablet, restarted the app, and could connect and live stream. Worked fine after a power cycle.
Third camera upgraded the same as the second camera.
Fourth camera upgraded the same as the second camera, but didn’t need to restart my Android app. Also noticed that the “Night Vision IR Lights” got shut off during the upgrade, but worked fine after turning them back on.
Fifth camera upgraded the same as the second camera, but got the “Firmware is Up to Date” splash screen around 85%. The “Night Vision IR Lights” got shut off during the upgrade, but worked fine after turning them back on.
So far, so good with this firmware version.
