Title: Flashed AK to F and now no communication
Post by: f1torrents on September 07, 2012, 11:20:07 AM
Hey there.
I recently flashed my spare ECU from
8E0909518F to
8E0909518AK
I used a KWP2000+

The flash finished ok. But once done there was no communication.
I am trying to flash in BOOT MODE with a Galletto 1260
But can't get into boot mode.

Any idea if I am screwed here or is there hope?

No matter how badly the flash went, boot mode should always work

I must be initiating it wrong then.
I will try again tonight, with a different power supply.

Is there an alternate pin to ground on the back of the PCB?
I think I saw someone grounding a NEC chip on the back?

OK so I can get into boot mode. I used ArgDub's me795040 tool (in boot mode) to read the eeprom and the file matches the one before I did the flash.

Galletto 1260 continues to say "boot mode inactive" even though I now know it is in boot mode.

Must be a driver or OS problem? Windows 7 32bit. I tried compatibility mode to xp SP3.
Any suggestions?

Changed to a windows xp maching and installed the drivers again.
I managed to get into boot mode with galletto. :)

Power supply cut out and im currently trying to get that sorted out.

Update...

I can get into boot mode and have a steady 14V with a charger hooked up.

The following happens.
Seed key OK.
Erasing ok
writing writing failed. (the percent bar does not move at all)

This happens with bot original F box file and the AK box file I was trying to flash.
..................................
Try to read ECU data.
reading ECU data .. Error DATAECU

I am now lost and dont know where to turn.???

Well today my plan is to try to flash some different revisions onto the ECU.
I have a few different box softwares to try.

-Fresh install if windows 7 32bit.
-Fresh install of galletto
-Constant 14v with a charger set up
-successful boot mode


Tried a random AF box file I had and it took it.
Im now going to try to put the original F box file back on.

Solved.
14V is too much for a china galletto.
12.5 seems fine.
Works every time now.

The 518F is an '02 and the 518AK is 03-04?

The bootloaders is different between these years, 02 had the earlier one and 03+ the later bootloader.

On the me7.5 f-box how are you physically putting the ecu in boot mode?  Is it a similar process as the me7's?... (Open ecu, pin 24... Etc?)

Mine is bricked i have an '02 f-box and trying to figure it out.

I have a kwp2000+ tool, is that going to work or is it required to have the galletto for boot mode?

It is the exact same process. Pin24 to ground, power ecu, remove pin24 from ground.

I opened both ecu's me7 and me7.5, the are*
Have you done it on anme7.5?

And how about cable and sw requirements?  I have a generic cable and also the kwp2000+ setup. 

Edit* ... There are some differences between the 2 ecu's

Me7.5 (top). Do i connect to pin 24 on the chip in the middle-left?

Find a chip that says 800BB. Then find the pin 24... then ground it :) .You count the pins from the dot

You can't cross clash the AK to F.
I haven't tried but apparently you can install either into your car and it will work.
But you need bootmode to recover.
