How to Repair 2021.3 MB SD C4 DoIP SSD Windows System?

I ordered a DOIP MB SD C4 PLUS with software xentry 2021.3 and was able to use this hard drive for 2 hours then it crashes. I was told me to change Bios to ACHI . That did nothing.

Please refer to the following operation steps to fix your system.

 

First start your PC and press the power button while it tries to load the windows to force it to shutdown, do this three times in a row to get the automatic repair screen.

You could also disconnect it from the outlet, click on advanced options.

MB SD C4 Blacklist Patch for S/N 101044

 Problem:

I have an issue with MB SD Connect C4 multiplexer (the old c4 i bought several years ago) with 03/2021 xentry.

It can access a C205. But failed to log in a C206 C220 d mod.206.016 year 2019 and a GLC254 300 4MATIC mod.254.147 year 2019.

xentry-login-failed

Possible reason and solution:

1.MB SD C4 Serial number 101044 was blacklisted.  It has problem using latest xentry.

2. SDConnect C4 firmware too old to support newer Mercedes benz. Borrow or purchase a newer MB SD C4 DoIP or MB SD C5 device.

3. Some blacklists can be bypassed by software.  Download the C4 blacklist patch, unlock serial number and try again. If don’t know how to unlock, contact our engineer via Teamviewer (your order number and device serial number are required to get the technical support.)
