Hello all, I was trying to read my flash with nefmoto, following this guide: http://nefariousmotorsports.com/forum/index.php?topic=6537.0title=

However I get this in return:

Validating flash memory starts at 0x00800000 and ends at 0x00900000.
Validation failed, ECU reports RequestUpload service is not supported. RequestUpload may have been disabled by aftermarket engine software.
Memory layout validation failed.

I am using the 800BB memory layout file, and my baud rate for my cable is 9600 for my cable. I don't have another ecu to test with, and I couldn't find a stock H box bin file to play around with. I am not the first owner of the vehicle, but I do know for sure it is an h box.

Another weird thing that may/may not be related is when I was tinkering with VCDS lite, and I do an auto scan, instead of controller: 8d0 907 551 H, it now says "THIS IS THE" and then cuts off. This may be unrelated, but the more important question is how can I read my ECU or acquire and H box bin file? If I can flash another compatable file over it that doesn't bother me however I would like to have a safe backup to go to just incase i fuck something in my tune.

I've done a little bit of research on the error but I would like to avoid purchasing a new ecu if I don't have to.

What on earth do you think this might mean? If you had to guess.

Did you read any of the stickies?

Whoever tuned that file did something odd to it. Normally that means the ECU is bricked from a flash attempt and is in recovery.

Well obviously that means that its disabled, however I was wondering if any of the gurus around here had a way around this.

No, I didn't. I dug around the forum enough to find the posts about proper flashing and memory layouts.

Ok, so to me that sounds pretty simple, just reflash the stock file right?

Do you want me to edit your post for you to get the quote tags right?

No, I didn't.
Please do to save everyone from having to post the same thing over and over

Yes. However, it may require bootmode depending on what the tuner who flashed that ECU did. It may also have a physical riser, which would prevent even bootmode flashing.

Or get a Galletto Cable, Read the rom off, Take the NOREAD out and flash it back so Nefmoto will work. But dont post the rom here for help, their responses will be in even larger font if you do...
