thankyou will download once alloud car
Hello, colud someone share with me firmware 1.70 bootloader hex? I need to try change firmware to ver. 1.45 and back to 1.70
I can not download ver. 1.70 because I do not have permission (probably yet)
Here you go.
You can do it if you have opcom china clone with real PIC 18F458. (however, you should know that the latest firmware is 1.67 for Opcom 181022a and 200603aEn) FW 1.7 is a Chinese marketing trick. If you have a fake PIC then when you change FW you will kill your cable. Your cable will work on the table but not connected to the car.

Hello I flash my opcom but can't get serial and version anymore
Read the interface description carefully. Read buyers' opinions, view posted photos. If it is FW 1.99 then it is 100% false PIC.
1) "OPCOM NEW" PCB without D5 C22 components - can be real PIC
2) Old Opcom with PCB V5 - if there is no D5, C22 and on the back the date is xx.xx.2007 (not 2013) it can be real.
1) Type 3 FW 1.7 (i have)

2) V5
