Report: 

A friend was trying to Read BCM porsche 2015 1N35H.
MDP can Read but can not Write
Xhorse VVDI Prog can not crack the MCU

Finnaly he decided to test the CG Pro 9s12 programmer and here is the result.

Step 1: Backup PFLASH

Connect CG Pro with BCM follow the wiring diagram

First need to read PFLASH and back it up

In CGPro software, select Immobilizer->Porshce ->BCM-1N35H (PFLASH Backup), press READ

Read PFLASH success, save data

You can see the whole dump of PFLASH

Step 2: Read DFLASH

Now we will read the DFLASH where other devices failed

Select Porsche->BCM-1N35H, check wiring diagram and connect

press READ

Read DFLASH success, save data for key adding

Step 3: Write DFLASH

Now we try to write on 1N35H where other devices failed either

Press WRITE

Writing data completed

Step 4: Test if other devices can decryt this MCU

For example with Xhorse VVDI Prog

In VVDIProg software, read DFLASH

Chip crack failure. VVDI cannot decryt this MCU.

Step 5: Read DFLASH & PFLASH again

Back again to CG pro

Read DFLASH again and make a key

Read PFLASH again to double check if our attempt with vvdi damaged anything

Data is fine, not damaged.

Now the DFLASH final reading to see if we can make a key.

This time save DFLASH data, i.e key test.bin

Step 6: Write key
