Hello, I read the Volvo XC90 ECU and saved it. I deleted the catalyst error. The car won't start anymore. I restored the original file but it won't start again. Please help me.

Please check the faults on the ECU after writing modified and original file.

Maps and modifications are on flash data, so you must read and write flash data normally. Please check how the EEPROM is corrupted.
Contact our support team on the ticket on www.hexprog.com  to check further.
