My Arduino UNO R4 Wi-Fi is bricked

Official Hardware UNO Family UNO R4 WiFi

My Arduino UNO R4 Wi-Fi is being recognized as an M5Stack - CoreS3 and the Serial Port's name is changed.
I have recently bought this board and randomly it started to show this issue. When i changed the board's type and tried to flash 0.6.0 using the Firmware Updater it couldn't update. The worst part is that when i open Serial Monitor it starts to show "SPIWP:0xee
mode:DIO, clock div:1
load:0x3fce3808,len:0x44c
load:0x403c9700,len:0xbe4
load:0x403cc700,len:0x2a38
entry 0x403c98d4'." Does somebody have a solution for this error??

(I am using a Macbook Pro M4 Pro)

It looks to me like the ESP32-S3 on the UNO R4 WiFi has dropped into its default ROM boot mode. When that happens, macOS sometimes identifies it as an M5Stack CoreS3 because they use the same S3 chip. The “SPIWP / load / entry…” messages look like the S3 boot ROM logs, which usually means the WiFi/copilot firmware didn’t flash correctly. I’m not completely sure, but re-flashing the S3 firmware in download mode might fix it

Seems like you messed things up

Hey @jim-p and @taha_zarif90, Thanks for the tip!

Let us know if the restore works OK

The restore doesn't work

That's not good.
Don't know what else you can do at this point.
We need an R4 expert, that can do some testing and I'm not one.

Is this an official Arduino Uno R4 or a clone?

I have mailed the Arduino Team about this situation. Also, today its showing Nebula S3 for some reason. This is the original Arduino UNO Ek R4 Wi-Fi

Then just wait for a response, I'm sure they will replace the board.

Hey @jim-p I finally fixed it and now it finally detects it. Thank you so much for the link!
