Default n55 JB4 PWG firmare update(integrated version) and rollback possibility - 10-01-2020, 03:54 AM

my current firmware is N55_FSERIES_OBDII_PWG_11_T1.hex
if i upgraded to latest firmware N55_F_PWG_INT_15_T1.hex and i faced any issues...i can still rollback to the previous version i have locally on the mobile app?
and it wont be deleted after upgrading to the lates mentioned firmware ....15_T1.hex

one more question.....the old firmware file name had OBDII.....the latest version found file name donest have it .......its just naming convention....doesn't mean the latest firmare found for n55 PWG (N55_F_PWG_INT_15_T1.hex) is not supported by my car & JB4 device?

You can go up and down on firmware as needed. If it's in the app under your platform compatible regardless of the naming convention.

I wonder if the N55_FSERIES_OBDII_PWG_11_T1.hex is actually N55_FSERIES_OBDII_ISO_10_T15.hex ISO firmware and you need to put the diode back to switch back from ISO to integrated firmware. In that case, I'm not sure if you update firmware first, then fix diode, or fix diode, then update firmware.
