The change of the id via sfdisk is only applied to the partition table. So that might be safe to change, unless you, at some time did not not follow one of the howtos to change the file system for the MyDocs-Partition, but only you know if you did. Am i right, that you do not want to recover some lost files from any partition, that was deleted, but want to have a usable partition for a fresh new MyDocs? Then proceed Code: sudo gainroot echo "unit: sectors > /dev/mmcblk0p1 : start= 64, size=51199936 , Id=c > /dev/mmcblk0p2 : start= 56631360, size= 4194304, Id=83 > /dev/mmcblk0p3 : start= 60825664, size= 1572864, Id=82 > /dev/mmcblk0p4 : start= 51200000, size= 5431360, Id= 5" > table Note: These are two commands, first to gain root rights, second to create the file table with the right content. Next dump it to the device Code: sfdisk --no-reread /dev/mmcblk0 < table Now the Phone is ready to reboot, you still have to apply the file system to the MyDocs partition and add the fifth partition inside the extended fourth partition Please ask if anything is still unclear.
sudo gainroot echo "unit: sectors > /dev/mmcblk0p1 : start= 64, size=51199936 , Id=c > /dev/mmcblk0p2 : start= 56631360, size= 4194304, Id=83 > /dev/mmcblk0p3 : start= 60825664, size= 1572864, Id=82 > /dev/mmcblk0p4 : start= 51200000, size= 5431360, Id= 5" > table
sfdisk --no-reread /dev/mmcblk0 < table
