i was using the cable for backup.
now i got the whole picture about this.
i'll just have to think which way to choose(if i solder the tristate to ground then i won't be able to check it the writing was succesfull, and that will be a problem because i have samsung nor and the clip it won't stay properly seated on the nor so i'll have to repead the process a few times until i get a good writing. on the other hand if I solder the tristate to the clip i might damage the clip because it's so thin and even if i don't damage it i don't think i wanna do it this way but i think it's the most convenient way)
i have to think about this
thanks for your support
