If your device doesn't show any led signal (red or green), you may can debrick your device by dumping a flash. |

@mm84, fwiw, I used the same exact programmer above and tried to make a dump and ended up bricking a perfectly good unit. I tried to make a dump of another one, and now Documented here: #8 (comment) I bought some replacement MX25L12835F chips, programmed one, but have yet to attempted to desolder / solder. According to this, #59 (reply in thread) you need to short circuit the xtal of the cpu. If you figure out how to do this, please share! |

@mm84 Though I didn't short circuit, I succeed in debricking two different devices. |

Is there anyone with the MX25L12835F_FW_20210331.bin dump? It seems that @brokens dump is related to Green UI version and my one is the RED UI version, so I got a "WIFI_BT" hardware error after flash @brokens dump :( |

Someone in other community succeed flash the RED UI version using Green UI version dump, although I don't know the version used. So it is worth to try again. |

It is strange, my device is a little newer than the brokens dump, I think they changed the hardware so that is why I am receiving this error message regarding Wifi and BT |

Ok, I successfully flashed the chip with 20200804 firmware on my CPlay2Air adapter dated 2019-12-25. No lights displayed during flashing; when I plugged into a wall-wort; I got slow red/blue alternating flash that speed up and eventually created only a dim blue. No wifi, tried in car, nothing. Reconnected to CH341A and the blue LED came on; reflashed. Anybody know what the slow to fast is? Recovery mode? Should I attach a USB with firmware? I know the blue/red did flash when I updated firmware previously. Would really like to unbrick this dongle. |

Flash @bronken dump (MX25L12835F_FW_20210306.bin), it worked on 3 bricked CPlay2air units I had but now they are all blocked on activation so it is alive but useless The device will flash red & blue/green after powering it (the device is updating the iMX DTB) during about 5/10 seconds and you will see it alive within 15 seconds ;) DiagnosticFixed blue/green LED = Blocked on uBoot : the flash is possibly dead |

Wow, 2 for 2 today! Success! The Activation screen through me for a loop initially, and then the car wifi interfered, but in the end; we have wireless carplay again! Thank You. |

If you are stuck on activation, all I did was scan the displayed QR code (takes you to 192.168.50.2) and once the web interface showed on my phone I got an "Activation Success!!!!" message on the radio display, I did have a solid red LED during this; then it went to flashing blue once I had CarPlay. |

Did a few successful direct flash of chip on a v2 dongle. Then I tried to dump V2 CFW 2021.08.24 to BIN and flash V3 unit but it didn't work... I get a "Hardware Error: Wi-Fi BT". It's running the CFW, just giving me the Wi-Fi error... Let me know if that should work or if you need to dump a special version that works on V3 devices. Looks like the bcm drivers are not being used since I have a dump from the v2 dongle. |

|
Oh, the good news, the CFW is running on the V3 -- so I can use the U2W.sh script, etc... so I'm wondering if there is a way to force it to use the BCM drivers (unless my dump is corrupt and the hardware error is a red herring). |

I think I have the v3 (idk how to check), and it bricked during a software update. I found this thread when trying to figure out how to fix it. I bought the USB serial adapter and reprogrammed the bios according to the instructions here (#72 (reply in thread)), but used the .bin file mentioned here (#130 (comment)). Everything seemed to go ok, but now when I startup my car, it loads CarPlay and shows "waiting activation" and a SSID/password; however, that wifi network never shoes on my phone to allow me to connect. Any ideas? |

I've managed to fix it. After flash CFW dump for v3 device I upgraded it with U2W_AUTOKIT_Update_2021.08.24.1817.img file by usb dongle. |

Thanks so much! I used 2021.08.24.1817 and named it "U2W_AUTOKIT_Update.img" and the update took. Went to my car and connected to wifi, then reset all settings from the web interface and it seems to be working once again! |

After many hours, I finally managed to flash the bin to my carlinkit mini device. I bought a CH341 kit and it took a lot of tinkering with the position of the clip to get it to work. I flashed the V3 bin, but I still have no LED light. It's weird because if I connect the CH341 clip in a normal manner, the green LED light comes on. I need to position it in a way for the light to turn off and then it will be detected and flash. If I then try to plug it into any socket using any wire, I have no LED light... Is the power delivery on my device dead? Or is it possible that because I had to have a weird clip position and the LED was off, that the bin somehow hasn't flashed properly (even though it verified ok)? Any help would be much appreciated! Edit: After some research I think that the mini uses a different flash to the 3.0, even though it's called 3.0 mini... I can't see any other reason as to why this isn't working. I've tested with a multimeter and there's full power. If I short the LED pins, they turn on. |

I had a bricked Carlinkit A2A that I tried to unbrick by flashing with many Flash_Dump.bin files until I got the MX25L12835F_FW_20221226_V4.BIN and the Adapter worked again, but it converted to Apple Carplay and stuck on the Activation screen. Only CP2A V4 FW (U2AW_AUTOKIT_Update.img) can be used for update. Any one can help to share the A2A flash dump ? or any suggestions? |

Does anyone have the carplay mini 2.0 flash file by any chance? I tried buying 2 from amazon to copy the flash files, but they were newer versions and were mini 3.0. The new ones have completely different PCBs and model names. I'm looking for the 'CPC200-Mini' model flash, not the 'CPC200-U2W' model. If anyone has the flash file, I would really appreciate it! |

Following on from this, I bought 3 separate mini devices off amazon which advertised themselves as cpc200-mini and they were all CPC200-U2W. I even bought one off aliexpress that did the same thing to me. PLEASE if someone has a cpc200-mini, can you share the bin with me? I'm just trying to revive my dead device so it's not ا-waste. Thank you! |

Thank you so much!
Currently I don't know of any place where I can get the BIOS to flash the V5. Have you tried to perform a firmware update via USB?

Do you know any available BIOS for CarlinKit 5.0 CPC200-2air / U2AC ?
I think the OTA update failed and now it's like dead.

Each version of carlinkit has its own firmware and BIOS version. I know you can make the V3 work with the V4 through a CF.

newest bootloader(from mid 2024?), at least on U2AC, makes flash dumps non-transferable and flashing somebody else's flash dump will just brick your device. try flashing mid 2022 and mid 2023 dumps if you have any |

Hi,
I recently brick my device after downgrade to 2020 version because I've stuck on 2021.03.06 version. I didn't know that procedure isn't allowed. Any chances to bring my box to live?
