Hello NefMoto community, this is my first time posting cause normally I find everything I need or don't have anything fresh to add.
On to the point,

I bought Eurodyne Maestro 7 and I flashed my first tune after having my car up on jacks for almost eight months. Turns out it was the wrong tune... It was labeled AWM however I guess my ECU called for the base tune under AMB... whatever...

Now the ECU is unresponsive, can't connect to Eurodyne Flash, Nefmoto Flasher (Not in boot mode or normal), and Galletto keeps giving the "Boot mode is inactive" error.

I think it's important I note I'm using the Eurodyne Tapp cable on 2014 FTDI drivers. Nefmoto recognizes the cable so I'm assumming it works.
I have the ECU on the bench right now and have tried grounding Pin 24 for bootmode.

Want to try the alternate method for boot mode but the pictures I've seen where people solder switches aren't of the ECU I have so I'm not going to go around touching contact points I GUESS might be it.

Tried 2009 FTDI drivers.
Uninstalled any and all software that uses the OBDII cables (VCDS lite and VCDS, all eurodyne software, nefmoto) and installed only whichever one I was trying at that moment. Nothing.

Any help is deeply appreciated, I really can't afford to spend any more money (Had to spend $70 on a DC Power supply... will probably return it and make an ATX one though lol).
If any pictures or info is needed I will gladly oblige and am willing to try any solutions again to verify.
Thanks in advance!

ECU: 4B0 906 018 DA

                                                                            [SOLVED]

Bought Galletto 1260 cable from eBay.
Got a hold of a laptop that never had any cable drivers/software installed. It was Windows 7 Enterprise, 64-bit.
Made sure to prevent windows from automatically installing any drivers. Followed the FTDI pdf on how to install the drivers to the letter.
Only installed the VCP drivers.
Installed the Proper English version of Galletto.
On first try Galletto gave me a write error at 60%, but I was beyond excited that it even began writing.
After a couple failed attempts (boot mode inactive) I deleted the driver software and reinstalled.
Worked like a charm the next time!
Hope this helps the next guy, all I needed to do was try a fresh laptop. Wow.
Thanks everyone!

Are you familiar with the bootmode process? Meaning, how many times have you gone through it? Have you verified the cables and software you're using are able to successfully put an ecu into bootmode yet?

I've never gone through the bootmode process before attempting on this ecu and this is my first time bench flashing anything.
Here's what I've done:

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.

Variations: amount of time pin 24 was grounded
~1 sec
~5 sec
~10 sec
~15 sec

On bench:

Basically what was described above except on bench.
Variations:
Saw a post here where someone said clicking read on galletto while still grounding pin works. Didn't work.
Read post saying to disconnect ignition and immobilizer after typical "ground pin 24, turn on power supply" procedure, then try using galletto or Nefmoto flasher. Also didn't work.

Nefmoto software tries 3 times to connect through boot mode before stopping. Also, I tried to connect the Nefmoto Flasher in bootmode at all speeds. Exited out of Nefmoto Flasher every time I changed speed too

Can you snap a pic of which pin 24 you are grounding?
Can you provide the pinout of the bench cable you are using?

Definitely clicking read while pin is grounded will NOT work.

Also, Nefmoto "bootmode" will not flash, but it can tell you if you are in boot mode or not.

Second pin from the right


Have also followed the trace on the board and tried the little lump of solder (no idea what the technical term for that is)



My "bench cable" is ghetto-rigged.
Cut slots in the insulation of the wires so I could slide the wire directly onto the pins, the two reddish ones are at +13.8V (based on power supply rating) Pins 21 and 62.
The yellow cable is my K line, it goes straight to my Eurodyne Cable K line pin. It's connected to Pin 43 at ECU.

At the furthest left the two bottom pins are grounded, and the middle pin is also at +13.8V

I quintuple checked none of the connections were shorting to any other pins.


And here is the Eurodyne Cable and its pins



I followed all the connections posted on the sticky for bench flashing,

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.
Disconnected

Disconnected

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...

I have a professional multimeter and know how to use it by the way!

Update: Just checked the voltage straight out of the Power supply when it's plugged up to the ECU. Reading +5V... Tested the powersupply by itself and it's outputting the correct 13.8V.
Sounds like bad news... Maybe it's a bad ground?

Okay, stupid question and will be pretty embarrasing if it ends up being the case........

Should I connect the ground terminals out of the ECU and Eurodyne cable to the neg terminal of the power supply?
I was under the impression the negative terminal would be -13.8V (Memory from my labs at school) but I forgot that in my lab our power supplies had two outputs, so two pos. and two neg., and we would have to jump them in order to get a neg. Voltage.

Here I only have a single pos. and single neg. terminal coming out sooooo...........

At the moment I grounded the entire circuit to a nice piece of metal I hit with a rotary wire brush......... lol

Yes, you need common ground on the neg terminal of your PS.

There are no negative voltages here.

Okay, so still nothing. Set up the power supply correctly this time (That was embarassing) but still nothing. Nefmoto Flasher gives same message and Galletto is still saying Bootmode inactive :\

What else could I check?

Are you using a Galletto cable?  Is this a 1.8t ECU?  Mine didn't work with grounding pin 24 and needed a 10k resistor between that pin and 10 along from it.

There's a picture on another thread.  Are you powering pin 44? too for the immo?

Thanks for the response!
I'm not using a Galletto cable, but what I did was hex edit the serial number from my Eurodyne cable into Galletto so it would still work... However at this point I'm suspecting the cable itself is what isn't letting me flash.
It is a 1.8T ECU and I haven't tried using a resistor. I'll go out and get a 10k resistor right after I get off work (4PM EST) and give it a shot after reading through your post.
Oh, and yes I'm also powering the pin for the immobilizer,
I'll get back with updates!

Bottom of the page, 10 resistor.  I don't believe in that method.

Where are you?  I'd be looking at buying a Galletto cable to get this working.  Drivers good?
