I replaced my HU6 Mid with a used HU6 High, set the PIN code, and the radio worked (CarPlay, AA, and navigation maps are unavailable). I took the car to Mercedes for coding, and now MBUX is stuck on the Mercedes logo. I launched my copy of XENTRY and saw this.
I removed the hard drive and followed the steps described in the guide by
dizel088. The drive was readable without any bad sectors (I ran tests), but Victoria SSD/HDD shows it's not perfect. I was able to create a RAW image of the drive using FTK Imager.
Every time I update Victoria, the number of UltraDMA CRC errors increases, so I bought a new Samsung EVO870 500 GB SSD drive. Now I would like to know which option would be best for me:
1. Obtain the disk image for HU6 and write it to a new SSD, then update the firmware and obtain the SCN from Mercedes.
2. Copy the HDD to the new SSD, then update the firmware and SCN from Mercedes.
