Did you check in the router’s browser UI if they are actually connecting or not? Could be connected but simply having an issue unless you literally check and they are not listed as connected.
Well I finally got around to doing this and it worked fine, both my cameras are now back on line.
Thanks for the help!
Still no response from Wyze on firmware .4679 bricking V3 cameras.
I have 8 cameras and two were totally bricked.
After several weeks since the update Wyze cust support still says "Their engineers are aware of the issue and are working on a solution.
I just downgraded the firmware on the two bricked cameras to .4054 and they both work now on that previous firmware.
Had a total of 4 - V3 cams go down after last update attempt, was not having much luck in hard flashing them. After noticing some people mentioned 32 gb or less cards, dusted off an older 2 gb card, formatted, copied only the extracted " demo_wcv3.bin " file to it, and it worked great, finally got the purple lite.
Thanx to everyone who posted to the forum, that’s what saved me.
Since you have to read the directions on how to flash firmware maybe they should change the word recommended to required. It would save a lot of people a lot of time. I have always used an old 8GB card I had laying around.
This is the worst of the worst can be done to an upgrade and product. It breaks the basic function of the cam, and requires a <32GB SD card, which I don’t have at all. Even worse is that this is my flood light cam I can hardly reach, and I have to unplug, and hold the setup button, and I have to call someone else to connect the power. How WORSE can it be!!!
I will tell everybody I know to avoid Wyze product at all cost!!

FYI I was able to format a 128GB micro SD card as “MS-DOS FAT” on my Mac, using the “Disk Utility” program, and use it to do the firmware update.
In other words, despite Wyze stating that the card needs to be 32GB or less, you can use a bigger card, as long as it’s formatted as FAT. I think the assumption is that FAT32 can only be 32GB or less. At least on my Mac, I was able to format a 128GB card as “FAT”, and successfully updated my Wyzecam V3 firmware.
I have tried to unbrick one of my V3 cameras and the firmware flash procedure is not working. I have tried with a 32GB formatted with FAT32. I never see the purple light and it just reboots to “ready to connect”. This is frustrating and I do not want to keep purchasing a new one when the firmware update breaks their own device. “Planned obsolescence”???
I finally used a Waze 32gb SD card, quick formatted to FAT32, copied the .bin file to it, and got the purple light for the first time! Loaded OK and fixed the problem. Had your problem for hours with a different SD card. Good luck.
I have the same thing and to be honest I don’t want to go out and buy a new 32GB SD card just to fix a problem that I didn’t create…
You can go smaller than a 32GB card, someone said earlier that they used an 8GB.
They are pretty cheap.
So this started with the update on July 13th and i didn’t update my cameras until the latter part of September when mine screwed up. So the firmware was screwing peoples cameras up for over 2 months and is still doing so and Wyze has yet to fix the problem? WOW.

Wyze bricked three of my v3 cams. I have left reviews on Amazon, BestBuy, TrustPilot, SiteJabber, PissedCustomer, and filed a complaint with BBB. I don’t expect Wyze to do anything about it.
Just wanted to say I had this issue with my v3 Cam on my v1 Floodlight. It out of nowhere stopped connecting, couldn’t reconnect it after deleting the device from the app, restarted the router, modem, and phone network settings - nothing was working.
I found an old 8 GB sd-micro, downloaded the firmware 4.36.11.4679, slapped the demo_wcv3.bin file in the root of the micro-sd card, turned off the breaker, held the setup button and left it held for 10 seconds after turning back on the breaker. it went to a light blue light, reset itself, and I was then able to connect it back to the Wyze app. My settings were still there and everything.
I’ll be waiting a long time to update the firmware moving ahead. My other v1 floodlight and doorbell pro cam attached to the Wyze app were also firmware updated at the same time last week but never impacted. 
thanks for the help in this thread!
You got lucky. I did exactly what you did a million times with 32, 16 and 8gb cards and could not get it to install a previous version of the firmware. Finally got Wyze to make restitution for the cams they bricked.
Having the same issue here. Wyze customer support was not helpful, I don’t want to buy another SD card just in hopes of being able to repair it myself. They refuse to replace or repair the camera and offered me $5 instead. I told them that this is insulting. I’ll be following up with BBB and CBC GoPublic.
I now have a bricked cam v3. Will not connect to local network.

I’m dealing with the same thing and it seemed to happen to only my V3 Pro cameras. I reset them and got them up again for 20 minutes and back off.
After getting really angry at Wyze over this, I left negative reviews on several sites and said I’d never use another Wyze camera. When I told them this, they gave me a credit for $99, almost enough to replace my three v3 cameras. Instead I bought several of the Wyze Cam OGs. Those cameras are better than the v3 and at $18 quite a bargain. I am now eating my words. I still think it was wrong of them to brick the v3 cameras and not be honest about it. Plus they’re just telling everyone “we’re sorry, your camera is out of warranty.” You shouldn’t have to do what I did to get their attention.
Did all that, doesn’t work. Light does not turn purple. Turns red the flashes red/blue. No purple. Goes to Ready to Connect
