Hi I need help , I have damage ecu in BMW X5 3.0
Old ecu is starting the car but loss of power, I bought
2nd hand ecu with same part number , then read ecu isn
It manage to retrieve the Sk and isn from ecu (new donour ecu)
Then went to cas to write isn in cas , auto hex says writing done
But car just cranks no start, when I check isn in cas it did change
But no start cannot see live data or anything just get a ecu rejected message
Any help

Please go to Indiv programming, check flash status there, if it is normal, then go to diagnose and check fault codes in DME.
If you don't see any fault related to EWS Tampering, then ISN written correctly and you have to check what's wrong there.

I will check tomorrow and report back
Thank you

I check individual programming on ecu the flash status is no data in flash

It is giving me ecu flash complete with error ref: 1019

First of all, please post only 1 message, I deleted 10s of duplicated posts.
1019 error is from internet connection. Please arrange a good internet connection then try again.

my internet connection is fine , updated the old ecu and it updated fine with internet , but old ecu is damaged on valvetronic side
ecu status is no flash data when i check on individual programming
