Fake Memory - Hacked MP4 Players

[etronicsland]

We have been getting alot of emails from buyers regarding mp4 players that they purchased, which have been hacked by mostly sellers on auction sites. Thus, for example, a user buys what he thinks is a 4GB mp4 player, but after formatting the player's memory, discovers it's actually just 1GB or so.

Unfortunately, this is being done by alot of sellers on alot of the "Big Name" Auction sites very often. But one way to avoid all these problems is to buy from reputable online retailers that offer a good WARRANTY, and have a solid RETURN/EXCHANGE Policy.

Want to further check your mp4 player to confirm if it's really hacked or not??

Then open up your mp4 player and look for the memory chip. It should either be a Samsung or Hynix.

check the REAL size of your chip, with this table:

You can find out the real size of your SAMSUNG chip here:

* K9x1Gxxxxx = 1Gb (GigaBit) = 128MB (MegaByte)
* K9x2Gxxxxx = 2Gb (GigaBit) = 256MB (MegaByte)
* K9x4Gxxxxx = 4Gb (GigaBit) = 512MB (MegaByte)
* K9x8Gxxxxx = 8Gb (GigaBit) = 1024MB (MegaByte)
* (1 Byte = 8 bits)

You can find out the real size of your HYNIX chip here:
* HY27UH081G2M = 1Gb (GigaBit) = 128MB (MegaByte)
* HY27UH082G2M = 2Gb (GigaBit) = 256MB (MegaByte)
* HY27UH084G2M = 4Gb (GigaBit) = 512MB (MegaByte)
* HY27UH088G2M = 8Gb (GigaBit) = 1024MB (MegaByte)
* (1 Byte = 8 bits)

A 2 GB mp4 player is not a 2 gigabyte player but a 2 gigabit player. 8 bits is equal to 1 byte and 1024 byte is equal to 1 megabyte and 1024 megabyte is equal to 1 gigabyte or 1 GB. But 1 gb Chinese mp4 player will have 1 gigabit memory which mean 1024 x 1024 bits. If you want to convert 1 gigabit to megabyte 1024 x 1024 divide by 1024 x 8 you will get 128 megabyte or 128 mb which is the real physical memory inside the player. So if you want to know the real memory inside these players go to the "system" menu go to "memory" find out what is given there. Say for example if you have 2 gb mp4 player you will see something like 2015 mb which is not 2015 megabytes but is 2015 megabit, divide 2015 by 8 which comes around 251 megabytes or 251 mb which is the real memory. So the real memory inside the chinese mp4 players will be as follows

1 gb player will have 128 megabyte or 128 mb memory
2 gb player will have 256 megabyte or 256 mb memory
4 gb player will have 512 megabyte or 512 mb memory

So the memory is not inflated or deflated but we are not clearly informed about the memory which means cheating. When the mp4 player is initially connected to the computer, the computer will interpret the memory size wrongly. For example if you connect a 2 gb mp4 player the firmware will show the memory size as 2015 m which the computer interprets as 2015 megabyte or 1.96 gb because it will see 2015 m as 2015 megabyte but it is actually 2015 megabit. It will not show 2 gb because some memory will be taken up by the firmware.

*Note:* The ONLY way to fix this problem is to solder a new memory chip in to your player and re flashing your original firmware.
