Hi Lotas
I just can't seem to solve the problem.
I try to write register 1 to 88 and register 2 to 42.
When I click on write everything seems okay.
Then I click on read and register 2 reads it to me at 4A.
How can I solve it? It doesn't seem to store the second register at 42....

ok. Are tantalum capacitors 4.7 uf at 10 volts and 22 uf at 10 volts okay ?
Is the voltage at 10 volts okay?

Yes, I performed the sequence given in your description
but it doesn't work.
It does not store 42 in the first register.
When I read it back it gives me 40.
Do you think it is a programmer's problem and I need to make the change?

Hi Lotas.
do you ultimately recommend that I do the modification or not?
I have ordered the tantalum capacitors and the 4.7 Khom resistors.
In post n. 455 you refer to a link where however in the schematic I do not see the two 4.7 Khom resistors.
Please suggest what to do? I am not able to make up my own mind.
I would like to remind you that my problem is that I cannot set the registers.

Some doubts:
Should C1 and C2 be eliminated, and should the tracks be connected or left open?
Is there any connection to be broken beyond contact 28 of CH341A ?...

Hi Lotas. Thank you for the valuable support you provide.
I have the same problem with my Samsung UE40MU6400UXTZ.
Unfortunately, I lost the original DUMP.
I purchased a new W25Q40CL, can you help me in any way?
My programmer is CH341A.
