you give me different info now
i explain what do

copy sistem file to change bootloader in tt memory without any card
run to change it
then patch tt with FA
pach is okey
then copy map in sd card ( 8 gb )
put it in tt and tt home give me update
update some system stuff and in sd card have some files/folder
when try run FA to patch map give me no found ttgo.bif file
when remove sd card cant patch map
map is over 2 gb .. tt memory is only 900 mb
i cant put map in tt memory and patch it


you tell me to copy all files from tt to sd card .. then copy sistem to change bootloader
but in 2 gb sd card i cant copy map because is larger size

maybe i missing something or do some wrong
thats i read from 1-2 thread ... copy system .. parch and copy map in sd card
but then .. tt and sd card wont work boot togheter
