ok im not programmer but if one chip doesent emty memory theres pcb faulty and if they say it its ok
That's nice to know.
At least they admitted their error.
To say the truth I was pretty surprised that they actually exchanged the deffective models, they gained my respect with that.
Sorry bad english but when i look videos i cannot see chip if they are different and dunno electric so much that i can spesify chips.
Don't worry bro, just try using more commas, dots and periods, they actually make a whole difference to the meaning of the text
