I found my FTDI cable wouldnt flash with galletto even when i edited the serial number in the software. Luckily i had the galletto cable and once i installed the galletto drivers (not the normal ftdi vcp drivers) it then flashed 1st time.
So maybe you could try using the ftdi driver but install the galletto drivers and uninstall the FTDI drivers.
Also have you given pin 121 on the smaller connector 12v

In car:
1.) battery disconnected, waited a few hours
2.) key in; ignition on
3.) Grounded pin 24 via foil surrounding ecu
4.) had friend connect battery (car was being powered by jumper cables connected to a truck)
5.) same results. Yet another thread going into 2nd page, and all the info to solve the issue is in one of the very first posts. You need to first ground pin 24, THEN power up ecu/turn ignition on. You are doing it in the wrong order. When the processor boots (and it does that when getting power) it needs to see flash pin 24 grounded at that very instant. If you are turning it on first, and then grounding the pin you are accomplishing nothing. |

He said he connected the battery after grounding the pin. |

Fair enough.
Could be a driver/cable issue then.

Does anyone else have this 10k resistor issue? Because there is only one thread on it here, and it seems to go against the grain compared to normal bootmoding.
Mine DOES NOT accept grounding pin 24 no matter how long I do it for. Bridging out the two pins on the thread I linked the whole time with a 10k resistor works first time, every time. No too sure if the ME7.5 ECUs/1.8t specific? have a different proc?
Next time I've got one apart I'll get the proc number and get a data sheet, but it's weird. No-one speaks of this issue. Is it because everyone's 2.7 freaks?

Never needed a resistor on anything I've booted. I use the power supply feed ground.

Did you check the proc data sheet? Pissing in the wind otherwise

I use a 120r iirc mostly about as a suitable probe lol. You just need to pull the pin low (recommend 10k iirc) but I didn't have any luck. Imo you really should use a resistor. |

And I forgot to ask, how do I use Nefmoto to check if it's in bootmode or not? I switch from KW2000 to bootmode, select my cable and then press "Connect Boot Mode" and look for what??
This is what the status window outputs:
Disconnected
Connecting...
Starting bootstrap loader upload.
Sent bootstrap init zero byte.
Sent bootstrap init zero byte.
Sent bootstrap init zero byte.
Bootstrap loader upload failed. Failed to receive device ID response for init zero byte.

So I'm assuming it never even gets a response from the ECU...
looks like it, what's he voltage on the can wires? try a 120r croc clipped across them too ecu might not be an endpoint (seen this before), shouldn't affect boot mode but will let the ecu boot so VCDS can read it etc Cable/driver as said I don't like how you were bridging pins in the car the datasheet (read it) explains boot mode. galetto, boot more is not galetto you can boot he ecu itno boot mode then 1 min later then open galleto, it will work. I used to have all sort of boot mode issues until I got a junk/scrap ecu socket soldered it up, used a 12v power supply from software and croc clips, I ground from the foil with yes a croc clip to the negative part of the power cabling. I then got a obd2 extender to make life easier taped it all up and never had an issue. |

I bricked my ECU the other day, i hadn't needed bootmode until this point and i too struggled but eventually got it using this Picture.
10k resistor as pictured left connected throughout the process.
Did not work plugged into Car loom
but it worked on bench with the ECU pins as pictured then +, GND and Kline on OBD cable.
I used MPPS V16 for boot mode flash and argdub tool + ebay blue KKL cable for 95040 in bootmode ( i couldn't get Galletto to work with mycable)
tested on two ecu's
1ML906032A
8N0906018BH

You'll have to trace the pins and see the difference, iirc there is a thread somewhere where you have to remove an smd resistor on an ecu type

Left connected DURING flashing is generally a bad idea. That is likely luck more than anything else. If in doubt, READ THE DATASHEET FOR THE ECU. I can't stress this enough. |

It's not luck applied to this though; I can confirm it too. Attempted to just brush during booting, grounded the pin individually and then soldered it on. Works when connected during the whole flashing process.
However, you're right that the datasheet for the ECU needs to be read first.

The 10K is not attached to the bootpin in this instance. |
