i need dump of printer DCP-J562DW (NAND FLASH)

Hello,
I am trying to repair a Dahua NVR4216-4KS2 that is not booting.
The main BIOS/firmware is stored in an SPI flash EEPROM (Winbond 25Q128, labeled as U130 on the PCB).
I have a CH341A programmer and I already attempted the following steps:- Identified the correct chip (W25Q128, 3.3V SPI flash).
- Tried to read the contents with CH341A Programmer software. The dump seems corrupted and I often get the error: “Chip with the contents are in disagreement.”
- Compared several chip type selections (24Cxx and 25Qxx families) to confirm it is indeed a 25 series SPI

Hello everyone.
I would like to know more about the following topic:
Nand flash on smartphone for data recovery.
I have been reading of people swapping nand flash from a faulty mainboard to another in order to save the data.
But I also read about encrypted data which to be read must been swap also cpu, or nfc or something else where is located the key to make the data being readable.
How does it works? How do I know if data are encrypted or where is the key?
I know there are also very expensive external socket where you can put the nand flash in...08-20-2023, 07:10 AM -
Hello all, as the title says, I'm very much in need of a valid firmware dump of a Anycubic Photon 5.5 3D resin printer. It's stored in a Winbond 25Q32, so it's 4Mbyte.
Here's a little background for my request. A few weeks ago I bought this 3D printer from a guy who had moved on to a PLA printer. I got it at a vey reasonable price, as it was in a defective state. The seller told me that he had experienced a power failure during a firmware upgrade, after which the printer appeared to be dead. He thought the firmware was corrupted in such a way that the printer was now bricked. As he...
