Have followed those but the unit never flashes green, just stays solid red :(
Are you currently on the stock firmware or custom firmware?

Make sure you plug your unit into a wall socket first, wait for 10 seconds before plugging in the USB after.
It worked for me after that.

Stock - have tried plugging in and waiting, no dice. Have formatted my drive as FAT32 with 1024 bit allocation size on Windows 10, have tried files called U2W_Update, U2W_Update.img, U2W_AUTOKIT_Update at root, but it never flashes green.

Tried updating OTA another few times this morning and still always fails.

Am I just stuck on whatever firmware my dongle currently runs?
 
Today I received another OTA update: 2021.04.26.1411. It did not fix my reboot issue unfortunately.

I read your original post. You have issue 30 seconds reboot. so I assume your dongle FW is before 2021.Jan.28.
and you could do OTA updating several times even though it is failed. so Dongle itself is not broken.

I'm not sure 30 seconds reboot issue affects OTA updating. Just in case, To prevent 30 seconds reboot issue during OTA updating, I suppose USB updating should be used. but it is never succeeded with USB. This is my understanding of your situation.

1. Plug the dongle to wall charger without USB. Normally LED will be solid RED color after 5 seconds. Is your dongle same ?
2. Plug your USB into dongle (Don't plug off the dongle from wall charger. Just plug USB into dongle), Normally LED will be flashing red and green., and don't touch anything until solid red +2 minutes if flashing.

Above 1 and 2 are my dongle LED.

If you stored 2021.03.06 FW on your USB, How about if you stored 2021.Jan.28 FW ?
At least, Many of Mazda user could resolved by 2021.Jan.28 FW even though we had issue 30 seconds reboot.

Do you have Red UI or Green UI?

Thanks for taking the time to post and trying to help sort the issue. I think my dongle FW is a December 2020 version, as I updated it when I received it, but haven't updated it since. I have followed the instructions and tried both the 03.06, 02.02 and 01.28 firmware via USB, but it never flashes green. I have used two USB sticks both formatted FAT32 - no luck!

Green UI.
 
Hi, my sister had problems with their carlinkit 2.0 on his 2018 Mercedes A class(NTG5), one day without doing nothing (my sister dont know how to update) the device got semi-bricked, i could install a new firmware (03.06) but now she has problems like spotify when it's runnig about one minute the device autorestart itself, if she doesn't play anything on spotify it seems to work properly. Someone has this kind of problem? I think i will rollback and then i will install 02.02 firmware version.

Green UI.
Ummm...
I'm guessing another possibility as below.

a. Do you have any other wall charger ? My wall charger can output 2.4A (Anker Power Port 6). if your wall charger output only 500mA, it might not enough power. (USB stick takes 200mA + Dongle takes ???)

b. Your U2W_Update.img size is same with me ?(ref. 2021-01-28 is 7,911,279 bytes, 2021-02-02 is 7,907,006 bytes, 2021-03-06 is 8,992,702 bytes)

c. Have you tried with "reset" on 192.168.50.2 ? then updating via USB with wall charger ?


I have no knowledge about Green UI and Read UI difference.
 
One question, if i install a custom firmware can i rollback directly to the version what i want?
Me too. I also have a same question. Now My dongle is CFW 2021-03-06-Based. so can I switch back to Official FW directly, or should I rollback to 2020.08.04_ROLLBACK.image (Official), then update what I want. or any other restriction.
 
I have the V2 version with the USB-C cable. I check regularly for updates, as I still have the reboot issue. The update popped up just yesterday. That means that they have tested it for a couple of days before they made it available, I think.
 
Hi. All I'm getting the JoexAuto MMB device (to be used in a 2019 Jeep Wrangler and a 2021 Toyota Highlander). I've been reading through this long thread as best as I can, but had a couple of questions that I haven't seen answered, yet:
- Any custom firmware for this device?
- Does the screen mirroring only allow YouTube or does it allow other media (video streaming) apps?

Thanks!
 
Hi,

Please find attached the firmware fix file for this issue. Please note this is only for Red UI versions.

I have the Original Carplay2air adapter with the fixed USB A cable. I was on the newest update just before the one that has bricked my unit.. I am 99% sure it was the green UI
Hi,

I am 99% sure it was the green UI see the attached photo of my screen when it actually worked LOL. Thanks for your help if you have a quick instruction on what file needs to be on the flash drive and the proper procedure it would be much appreciated.

Thanks again for the reply.

Is there a way to flash this 04.26 to a version with the Red UI? I don't care what color the UI is since I see that this one now has the newer "Background Mode" that was on the Red UI version... that's the way I tend to launch so it doesn't throw up the ugly splash screen. If I change the file name to include the word AUTOKIT do we know if that will work?

Does anyone know what Background mode means?

Yes... background mode means it skips showing you the ugly 'connecting' screen. It connects in the background and once it's connected, just launches to Apple CarPlay. It's a nice way to look more integrated.
