use hex editor to read your dump file you can setup 8 bytes or 16 bytes

The chip could have several numbers including date codes, but the important one has 24, 25 or 93 in it. It will usually start with a letter for manufacturer (AT for Atmel, M for STM etc) but not always and may be followed by a letter or two for series. It will end in a number giving the memory size, in bits not bytes.

types of eeprom:

eeprom 95080.
cmos eeprom.
eeprom transistor.
eeprom 28 pin.
eeprom spi i2c.
eeprom clip soic 8 pin most used by stb

How to DISABLE the data WRITE PROTECTION on an EEPROM chip (using an Arduino or a programmer)

Eeprom and flash and other roms are implemented with pages, blobs of bits that all erase in one action. You can typically only erase whole pages at a time. Normally they erase to all ones, but some are the other way around, for the erase to all one case, you can think of it this way the only way to "write" ones is to erase a page, but you can write zeros on a essentially a bit by bit basis. (by writing a byte or whatever the smallest write is and only changing the zeros you want).

write protection means just what it says, writing protecting the whole part, or fractions of the part or a page by page basis as per the design.

sometimes the write protection uses pins being pulled high or low or the pins protect the ability to unlock things after being locked. again it is on a design by design, vendor by vendor basis as to what features are there, and you simply read the docs and experiment.

how to dump NAND BGA ( ds831ns set top box s@y)

there are different types of eeprom

SPI
I2C
Microwave
Nand
FWH
Mcu

and there are diffrent types of soldering and pin connector as you can see here below

soldering:
traditional
smd
bga ( in bga soldering the pins are not visible because they are inside the chip so is not possibile to soldering nothing)

pin connector:

today will see how to dump BGA nand (NAND02GW3B2DZA6)

first we need to search the datasheet on web then will see all information

now we use can use the software broadband studio 3 (broadcom) because the cpu is bcm7325

________________________________________ ________________________________________ _________________________
we can use also iFix Universal Programmer RT809H but you need to use hot air only that inevitably you have to remove the chip because since he has no "teeth" there is no gripper that holds.

here the tutorial
