then bought an 16gb kingston sdhc card…(thought i had some ancient cards at home…but no… 
)
anyway…system didn’t like it of coz…sdcard err…
tried format and partition with win10…and the app that someone listed here before from sdcard bla bla site…nope nada didn’t work…
although windows found it right away without issues!..(soo it was the BenF fw)
…aaanyway…did last attempt before starting chase on a ancient 1-2gb sd card…
partition and format a 2gb partition with Paragon partition manager…look and behold!..it worked! :shock: :shock: :shock: :lol:
cheers! just info if someone…in same situation =)
pic on new tf slot with sd card inserted…without making any slots in case…thought that whould not be necessary?..if you think of doing this…shift the card holder position as far as possible to still be able to solder the pins!..then the sdcard will still fit nicely inside the case!
see pic…

Wonderful! Thank you for sharing your success story. I am sure it will give someone hope to do the mod themselves.
