Title: bricked me7.5, need a fix!
Post by: Omega_ on February 14, 2016, 04:08:51 PM
Hi guys, i'm stucked in a bricked 32hj ecu! First i tried to flash a bin that later i noticed that wasn't cksumd correctly, and the car wouldnt start. I cannot write any other file, except in boot mode shorting pin 24 to ground, always with mpps, after boot mode the car start and after a second dies, but i'm able to rewrite the file or get ecu id in normal mode one time! After that the car cranks but wont start to another boot mode flashing. As i think the flash is written correctly but immo cuts, and i dont know how to fix it! I read/write over obd all times with mpps and my vcds cable won't work (flagged i suppose).. Any help would be highly appreciated!

Your ecu is not bricked. You need to disable or re-pair the immo. Moving thread to immo section... PLEASE READ THE STICKIES THERE.

Thanks for reply and redirect! I've already read all posts about it, but I haven' t understand how to disable immo or how to rewrite previous immo bin if i havent a dump.. I need a kkl cable and 95040 Program in order to access the immo memory location, but how it overwrite by a bad flash? Isn't there any how to do it like on EDCs platform, all over entire flash writing?

What's the original sw #'s and version? Why not just write that back? If you need a complete file get one from the original file section. As long as the ecu is originally from the car and you are using the correct Immo version software it should be as easy as writing the original file back to the ecu in bootmode. Cross flashing different software versions without knowing what versions will work will result in this mess.

1 start and then bricked again is still bad sums. not because of unpaired immo.

Ugh, you're right.


OP, please post the output ot ME7Check/ME7Sum on your file(s)

it sounds like a combo of the 2 to be honest. starts and cuts off, then bricked.
but who knows what some of these people do.

I think he's trying to flash the "wrongly checksummed file" back onto the ECU time and time again.  I think that this "wrongly checksummed file" is actually a Stage X file stolen from someone and he's wanting to use it without doing any work.

But, that's probably a conspiracy.

I'm not currently on pc i will be on later to attach files! The car was buyed with a mapped file already on it, i've previously made some smoothings and flash no problems! I was using ecm titanium as tuning Program, that auto correct cksums, the latest was tuned in tunerpro and i forgot to save it over another trying that hadn't been cksumd with als and nls added! The stock file i trying to flash is downloaded from here!

Ok here we are
the ecu is:

Bosch
0261207436
1037362287

files are in order:
nefmotostock.bin the file that i'm trying to recover in bootmode all times, as intended stock file downloaded fro here.
mapped is the file originally found on ecu, when car was buyed
smoothed is a little mod to mapped same written and no problems
latest corrupted is the file that create this problems

txts are cksum reports.

I always trying to recover to stock file, and only then put on a modified

The mapped one contains modified code.  Why?  I thought you added NLS to the smoothed one?  So you're trying to write an ORI to the car when the "mapped" one was the original, but it has modified code?

Who mapped it previously?  I think you're flashing a wrongly checksummed file AND because you're flashing the ORI back on, it's triggering the IMMO because the previous map was Revo or similar where the EEPROM is tied to the flash.

It's a compound of errors.
 
Also, why have you added NLS?  Do you have rods?

The smoothed is a mod of modded, because the car had a unlinear boost, and worked well. Yes the mapped one was the map that i found on car, and i don't know who, a tuner from Milan here in Italy, the vendor said that the tuner was his friend that worked in vw.
comparing maps in hex editor there are a lot of undefined sectors! but why if i try to restore the mapped in boot mode it won't start at all? if i immo off the stock bin and then upload again the mapped one should work?
edit: nls was added only at lastcorrupted bin

Why immo off?  It's a waste of time when it can work.

If you flash the mapped one back on - the one that the car came with, there should be no issue.  I don't know why there is modified code though, which makes me think that the original tune has some sort of protection that is stopping the car starting.

Personally, I'd start with the original file and a matching original EEPROM and start from there.  There's too much chopping and changing files and you don't know where they're from.

Also, do you have rods?  NLS is NOT needed on a standard car.  You'll destroy it.

Ok i've tried with the map the car come with, same as nefmoto map, car starts but shuts immediately! whats next?
as the vendor said car already have rods and pistons, nls doesn't interest in this moment i only trying to start the car properly!

Post by: adam- on February 15, 2016, 06:18:34 AM
Either flash an original matching EEPROM or attempt to recode the ECU, but I doubt it'll work.  So you'll need to use an ORI and a matching EEPROM.

As ori you intend the map the car came with? so do i need to rewrite the eeprom trough 95040 program? what eeprom file do i need for this purpose? i don't understand this step


Title: Re: bricked me7.5, need a fix!
Post by: nyet on February 15, 2016, 12:26:37 PM
Stop fucking around with other peoples files. It is NEVER a good idea.

I don't know how many times this has to be said.

If you aren't comfortable flashing the eeprom, purchase a complete stock ecu.

I'm sorry if i am misunderstanding, but it's a forum and i search help, it wasn't clear to me what to do and i asked. am i wrong? i don't fucking around with other tunes i dont need it, the car came with the map already on it, i didn't know that is a restricted and modified immo, as i would know i wouldn't getting in trouble.
now, i have a corrupted 95040, i need a new one bin, is there someone that can help?
sometimes i write something different as think, english isn't my first language sorry

To be fair, I think you've got a fair grasp with only 9 posts, you've managed to read and write (in bootmode), which is an achievement usually!).

There will be a matching EEPROM and file in the requests section I'd've thought, have a search. :)

Sorry. Frustrated because normally noobs start with other people's tunes thinking it will help them, and it always ends up in tears.

I thank all of you For help, i really appreciate! I cant get my vag cable to work so i've buyed another one, and wait it to Read/write eeprom.
Anyway i would look around For a new ecu, just in extreme, but those things are expensive as s***!

a tuner from Milan here in Italy

It's Italian tuned  ;D

In that case, you have some reading to do, and need to find a copy of a stock eeprom/flash pair.

Post by: Omega_ on February 16, 2016, 01:03:38 AM
The only thing that i found confusing  is regarding adaption!
In a few posts someone told that is possible to flash the new eeprom and inject vin and immo bytes later via vagcom, but as the key and cluster doesnt match infos stored on new 95040, wouldn't this block obd function? So i need to put all those first via hex editing reading the current eeprom and put the new one already matched or i'm mistaken?

Hi all, i had my vag cable yesterday and after some frustrations getting bootmode i've managed to revive the car! I don't know why but after i've installed drivers related to cable it won't bootmode anymore, so i put on a virtual machine and it work like a charm even out of vm itself.
So i will thank all you for help, here is the eeprom that i read from ecu if someone is interested to take a look at !  ;D
