HINTS when reading/writing flash memories of ECUs

If you experience problems with reading ME7.x memory better remove fuse 11 and fuse 15 to prevent disturbing of communication from the instrument cluster and try again.

When flashing the device please always read and save first the original flash!

Please, stop all screen savers/power saving options and unused application during the flashing! Please do not do anything else on your PC while flashing.

Please, take into account that the reading/writing of the flash will take a long time (especially when CAN connection is used) – as result the battery may become flat.
