I had some trouble reading my car, tried to read with a few different memory layouts. Finally I realized that the baud rate had to be readjusted down to read. I got a full sucessful read which I am posting here, with the 29F800BB layout.
The car wont start now, what should I try next? I could really use some help on this.

Is the ecu still live? can you connect to it with vcds or nefmoto software? if so flash your read back if not live you bricked it
good luck

Yes, I can connect to it again. I'll go and try to reflash the file I just read.

Genius! It's alive. Thank you for your quick reply and consideration for new-guy cludges. Now on to find an appropriate XDF. Thanks again

Could you post your log file so I can see what happened? I'm wondering if your ECU thinks that it needs to be reprogrammed because I asked it to validate it's checksum during the read.

glad your up and running, the ak is very well defined and you could use that to make your own xdf
good luck

Go figure. I get one of the oddballs. Where do I find this number for my car? Is it the "Vehicle Manufacturer ECU Hardware Number" or the "Calibration Date"? |

maybe stupid question but after READ did you click Disconnect ? I had an issue once....When you write it disconnects automatically , when you read it doesnt. I don`t know how this can effect the ECU , when programming is complete

Thanks for posting the log file. Very strange that reading the ECU would cause this issue. Definitely something I want to fix because most users don't expect a read to cause the car to stop working.
Things I can think of that the NefMoto software does that could cause this:
-Not disconnecting after a read
-Doing checksum validations before reading each memory sector may cause the ECU to think it isn't properly programmed
-Not doing a checksum validation for the whole memory range when finished reading
It was also weird that you could only connect at 52800 baud. Other baud rates were rejected with a security access error. I wonder if it was the specific baud rate that worked, or if it was something to do with changing the baud rate and starting a new diagnostic session.

Its very common problem with all flashers. I know nothing about KWP etc, but from my expirience its very important to turn ignition off even after identifying otherwise you will get "programming not finished".
