VVDI Prog 4.8.8 CAS4 R/W reviews:

1. Already tried it and need to remove resistor(not capacitor) as described. No read if I don’t desolder that component.
2. I test on2 cas4

   Cas4 f10 it could not read without removing 1 resistor

   I tried also on f06 with cas4+ also same result

3. Have to have remove a component/resistor 😞 but still awesome!

So, cannot read/write CAS4 without removing component?

The answer is:

mostly of those types no need to remove components, but maybe few of CAS4 the component affected on clock signal, better to remove it if crack failed
