How many ways to read/write CAS4 data? ACDP the best?

Have collected common ways to read and write BMW CAS 4 data, including new (Yanhua ACDP) and old methods:

Method 1: cut down cables
Method 2: remove components
Method 3: lift pins
Method 4: done by ICP

In detail....

Method 1: cut down cables

You should disable 2 connections in the PCB; that is, 2 cables need to be cut
Then need finish connection as before, after data is read and written
It’s risky and may lead to damage to the module



Method 2: remove components

You need remove 4 components in the board
And then desolder all after data is read and written
It’s time-consuming and requires desoldering experience




Method 3: lift pins
You should lift chips and put them back after all is done
Some data might be lost because of bad desoldering
It’s risky, difficult and time-consuming, easy to damage pins on the chip





Method 4: done by ICP
ACDP is the best, compared with all methods before.
Easy:
Board with ports is used instead of desoldering
No need cut down cables, lift pins, remove components and desolder anything
Secure:
Data is read and written with security, with pin smart detection
