I searched google
last night and only found questions but no answers about a possible port for the magicjack. I was wondering if it would even be possible. It has a HY27US08561A similar to a cell phone. I looked it up and found this on the hynix site :
The HYNIX HY27(U/S)S(08/16)561A series is a 32Mx8bit with spare 8Mbit capacity. The device is offered in 1.8V Vcc Power Supply and in 3.3V Vcc Power Supply.Its NAND cell provides the most cost-effective solution for the solid state mass storage market.The memory is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased.The device contains 2048 blocks, composed by 32 pages consisting in two NAND structures of 16 series connected Flash cells.A program operation allows to write the 512-byte page in typical 200us and an erase operation can be performed in typical 2ms on a 16K-byte(X8 device) block.Data in the page mode can be read out at 50ns cycle time per byte. The I/O pins serve as the ports for address and data input/output as well as command input. This interface allows a reduced pin count and easy migration towards dif*ferent densities, without any rearrangement of footprint.Commands, Data and Addresses are synchronously introduced using CE#, WE#, ALE and CLE input pin.The on-chip Program/Erase Controller automates all program and erase functions including pulse repetition, where required, and internal verification and margining of data.The modifying can be locked using the WP# input pin.The output pin RB# (open drain buffer) signals the status of the device during each operation.In a system with mul*tiple memories the RB# pins can be connected all together to provide a global status signal.Even the write-intensive systems can take advantage of the HY27(U/S)S(08/16)561A extended reliability of 100K pro*gram/erase cycles by providing ECC (Error Correcting Code) with real time mapping-out algorithm.Optionally the chip could be offered with the CE# don?t care function. This option allows the direct download of the code from the NAND Flash memory device by a microcontroller, since the CE# transitions do not stop the read opera*tion.The copy back function allows the optimization of defective blocks management: when a page program operation fails the daata can be directly programmed in another page inside the same array section without the time consuming serial data insertion phase.This device includes also extra features like OTP/Unique ID area, Block Lock mechanism, Automatic Read at Power Up, Read ID2 extension.The Hynix HY27(U/S)S(08/16)561A series is available in 48 - TSOP1 12 x 20 mm , 48 - USOP1 12 x 17 mm, FBGA 9 x 11 mm.
Just wanna know if it is possible ? Think i seen a cellphone flashing utility for it on some chinese website can't remember the name though damn. I'm gonna look again when i get up and hopefully someone will reply and let me know it's even possible or if i'm just wasting time with my newb attempt lol.
That's a flash chip. If it has a microcontroller, it's something else. Just list the markings for all the ICs in the device.

so someday it could be possible to use majic jack? at least that thing would come in handy for something
well the HY27US08561A is not a microcontroller, its flash memory so one would need to know in particular what mcu is used in the device if any before anybody could say if it could be used or not or weather or not it would be practical.
I know the device is basically a usb sound card with flash memory to store and run the magicjack soft-phone program. As far as I know only the software on the flash ever gets updated by the company.
Would also like to know If this is posible
that would be a great port :)
All chip information on a magic jack
Magic Chip : 0833 p5675-010
hynix KOR : hy27us08561a tpcb 839f m7sf2779qa1
Cosmo 3010 814 i31 C ( may be 614)
No named chips
The board it self has a lot of extra numbers on it if any one them would be relevant let me know
so does that information tell any one if any of those are micro controllers or not ?
The Cosmo chip is just a photocoupler - often found in cordless phones.
