Is it possible to brick V5 connecting to 121241i or 13223d EN?
Everything working with 120309a but something tempted me to run v5 with these versions.
Cause - no connection, no bootloader...
I've got embosed Pic so I thinked that it's safe to make some tests.
Is it posiible to flash brute force Pic by Willem programmer?
Op-ComFut gave me response that firmware is 07a and nothing more.
Shitty China-clone, it's time to buy Tech2 or MDI.

No it is not bricked, "HQ clone" software can't physically harm device. Also your PIC firmware is perfectly fine, so don't bother trying to reflash it. What HQ clone "protection" does is, it makes changes in FTDI EEPROM which are always fully reversible.
In case of OP-COM B2 (HQ clone) with wrong user data bytes ("protection") it silently changes PID in device driver. In case of OP-COM V2 product descriptor (china clone) in addition to that it also inverts TX pin.
The solution is quite simple. Go to device manager, uninstall the driver for USB Serial converter, rescan for hardware changes and let Windows reinstall the driver. Then go to MProg and reflash .ept file.

OP-COM is not a bad hardware, china clone V5 is identical to HQ clone and to most real OP-COMs. It is cracked HQ software "protection" that is creating all the mess.
