OP-COM V5 Bricked
Hi, does anyone know how to unbrick a V1.59 (V5 PCB) ?
It's got a real PIC and accepts flashing but sill does not connect when in the car. I have other OP-COMS working fine so I can test any ideas. wbr |

I would check ftdi read and check eeprom with ocflashpro/ opcomFUT it's probably ftdi because your pic is accepting flash. How did you brick run opcom professional software ? Also find v6 brick fix thread and fantomel thread you will find all the software and files you need Heres one of the threads that will help you : https://cartechnology.co.uk/showthread.php?tid=5443 If mine or others posts and info are helpful please give thanks/rep

It's a V5 not a V6, after a flash it failed, flashed in the past ok, not sure why this was different. V6 fix does not apply here as the PCB is different, and FVDI is ok. I have other OP-COMS so this is low priority but would like to fix it wbr |

RE: OP-COM V5 Bricked
Do an Interface TEST in OP-COM -> Settings
Do a firmware check using OCflash only if your previos test in OPCOM it doesn't show your firmware Check drivers versions and if there is Load VCP tick it in the opcom drivers Properties-> Advanced tab No need car connection. Are you using windows 10? Good luck P.S.- This is the schematic that you requested. - take care this has a lot of bugs. It is what you can find on web. It is not made by me. |

Thanks for the Schem, is this a V5 or V6 schem? (Loading VCP will make the tool car dependent, tests will fail without the car) wbr |

RE: OP-COM V5 Bricked
Schematic is for Revision B. And it is pretty much as a opcom v5 if you want but it can be used in opcom v6 as well. It is helpfull but as I saif it has few bugs and difference then in a chinese clone. I mean if you make an opcom using this schematic it will not works at all
But as you say your issue it is the MCU. Belive me I had one of this tool as your in my hand from a cartechnology member from Germany. I fixed by changing the MCU with a real original programmed one. I was very surprised that chinese soldered "fake" MCU in this opcom v5 hardwares. Good luck |

Do you have REV V1.99 flash? maybe my file 1.59 was corrupted and bricked the MCU? Was sold as having a real PIC but Chinese don't always tell the truth Do you have a link to the PIC you used? wbr |

RE: OP-COM V5 Bricked
Mate if you can see the firmware and your test it is OK in opcom then there is no corrupt firmware.
But if you can see the firmware and test OK then your MCU is blocked. This is the protection of this MCU used by Chinese in this time. Don't waist your time. Change the MCU with and original programmed one and you will see that will works from the begining. You can use any real firmware. Fw1.99 it is a fake one. Use fw1.39. One more think. If you can test the interface and you can see the firmware version and test it is OK then you cannot have a corrupted firmware. You just have a blocked Chinese MCU. Good luck |

Yeah I know but the thread is helpful for solving problems and some of the software used is posted along the way If mine or others posts and info are helpful please give thanks/rep
