can anyone help me im new to this and would like to know how to chip my virgin media box and what i would need to do it

[ouzi1212]

what type of box u to have, make sure its not subbed box.

[sqwidge]

everything has a printer port i have a fifteen year old laptop and that has a printer port on it, it has 25 holes in it and is usually some weird yellow colour

[sqwidge]

sorry dude i stand corrected i just got offered a new lappy and it has serial com port (9 pin D) but no printer port (25 pin D), how weird is that???, if yo have neither then your stuck as it only works on true ports

[sqwidge]

Does anyone know if you use a converter from 9 to 25 will it work for J-Tag?

converter wont work mate, jtag only works through printer port only...

i dont get why you cant use a com port to do this, there must be a way around it im also surprised that this wouldnt work (see below) as technically it turns your port into a printer port if you dont have one

wont work in serail m8----needs bios on pc to have printer port set to ----lpp i think dont qoute me though---its the 1 that acepts more advanced connections though.....

if u wanna build your own jtag check out fta 101 downloads ---theres a revsied diagram that deffo works as thats what i did---after i built the 1 that had a wire worng so make sure u get the revised 1-----if it dont work--it was only wires 3-4 on the printer port end needed swapping.........................so not a full rebuid!

i have posted about this myself sdomewhere on here..................as red diesel told me about revised 1??

if u have solder an iron u can get bits for under a fiver from maplins---------------
i also build a max 233 bit dearer to build cuz a chip was dearer diarams in fat haynes guide?

rather than using pogo pins -----when i made my jtag i used telephone wire 6-core [stb end],
solid core that can be pushed into hole in stb when sodler point has been heated a little, then when done just snip wires, making sure none can touch obviously.........


all the info u need guys his right here ........if u read in tech watch i mean,.,


easy and cheap------whay spend 20+ when u can do it for a few quid......
