I formatted my phones internal storage with ntfs and now it doesn't appeared in usb mode and also not in file manager. And phone's feature like gallery, camera, recording etc are not working. Is there any way to format internal storage again with fat32 file system? I think there should be a way in ADB to format it. I don't have much knowledge about it but think it is easiest way!!! Please someone help me....
It is possible. I found some instructions here that partially apply: http://androidandme.com/2009/08/news/how-to-manually-partition-your-sd-card-for-android-apps2sd/
DO TAKE CARE, IF YOU DO NOT UNDERSTAND COMMANDS WELL, DONT TRY THIS OUT.
The difference is that you just want one partition in fat32.
mkpartfs primary fat32 0 [last MB] # where last MB is visible using
parted /dev/block/mmcblkXXXXXXXX . Also the article is about an sdcard.
I'd recommend checking carefully if you have the right block level device before issuing any partitioning commands!
When using the appropriate block level device, little can go wrong, as you currently have no access at all.
 Personally, I'd try to install a new recovery using Fastboot, and then use that recovery to format your internal storage. A lot easier and safer IMO.
