He is discharging the charge from the capacitors  Maybe the internal RAM is able retain the data because of the charge in the caps. And because the RAM is not empty the CPU does not enter in boot mode. Sounds odd but I guess it could be possible in theory. |

Hi guys, Maybe I was not clear enough - sorry. ground is not minus. connecting plus and minus in´s in deed no good idea.... And: I fully agree, this all might sound strange. But if you want to be convinced: I still have this ECU and I can reproduce this as often as you want. I was about to throw the ECU away because I could not get it in boot mode. But then I saw this discussion about grounding the power supply  now everything is fine again  maybe simply try it Nottingham and give a feedback... BR Greg |

Did you have any solution with the Infineon chipset beside using a chip burner?

how are you trying to set it in bootmode, my volvo is later me7 with Infineon chip, and if you ground it out, the ECU is toast, you must use a 1k ohm resistor on the bootpin, otherwise you see one spark on initial contact, and then nothing, ever again

There are few members reported successfully get in to boot mode by grounding it without using a resistor. You are right about the spark, but mainly that pin was grounded without any power to the unit at least in my case, however I can't get it in to boot mode but It start normal and drive normal after I put it back to the car.

I'm pretty late to this party, but I found this thread while searching for a solution to the same problem. I purchased an Ebay ECU and cannot get a flash read in any way. For kicks I tried the attached utility and ended up with a readable .bin file.  I thought that this may be of use to a couple of folks here, based on posts in the previous pages. Now if I could just figure out how to get in via bootmode and write a copy of my primary .bin over this... |

This revo read allows you to read Revoed cars through OBD ?
Anyway you can read Revo in boot mode just fine.Some important maps are just in different places more than once

Saw this picture somewhere.... could this be right? I've never seen jumping pins on the flash with a resistor before, it's always been a single pin to ground.

Methinks you should ohm that pin... |
