RE: REPAIR ERASED OP-COM CLONE BOOTLOADER FROM PIC18F458 MCU
Hi!
I have an OP-Com 1.99... I received it, and it didn't manage to connect to any of my cars. According to a readme included on the CD, I should update to v1.59 through OCFlash, but checking on the board it was a v5. I did it, and it kept on not connecting to the car. However, it can't flash any other thing now (latest fw file I have is v1.59), neither OCFlash or OPComFut, both read as v1.59 and no issue, but when trying to change to v1.39 or any other it says bootloader is empty and all these messages... On MProg I tried with different ept files, the serial changes successfully, but no real change is made... I have read lots of posts here and there, but no luck  Any idea? Any other fw file I could try? Thanks and regards! PS: My OPCom board is as attached (PIC18F458 I/PT 1823SVU) ![[Image: NtJcY6a.jpg]](https://i.imgur.com/NtJcY6a.jpg)

Don't waist your time
Your MCU is not a real Pic18F458 Even they marked opcom v5 actually the hardware is opcom v6 Its easy to check it out. ( I will not try again and again to explain how to check on PCB if you have real Pic18F458 or not because as I can see the Chinese watch this kind of threads in forums and they will know what to change to cheat you when you just see the hardware PCB. Try to use it with opcom china clone 2010 Don't try to flash other firmware in your MCU because you can destroy it and maybe you cannot use it anymore. Good luck |
