Problem:
Foxflash reads Mercedes MED17.7.2 ok but failed to write, what should I do? What’s going wrong here?
Solution:
Don’t write All. You don’t do a clone, so work on flash only.
Usually for modification you shoud write flash.
Write flash only and after you write eeprom, one by one, don’t write all together to correct checksums.
You only choose write all when using original full backup read to write again back, never modified fls nor modified eep using full backup write. These when modified write each separately, and if tool doesn’t do cks correctly, do checksum calculations seperate using proper software, and choose the option not to let tool do checksum. You can calculate checksum with other software, like winols or lsuite.
