can you please suggest me. memory card is not showing in recovery mode how to solve this problem because i want to install android lollipop in my Samsung ace duos 6802.
In recovery, go to
mounts and make sure
ext_sdcard or similar is check-marked.
Also try disabling/enabling
MTP Mode (if you are on twrp) in
mounts if it still doesn't mount along with above step. Cant say how is that related, but this did the trick once for me.
