SO basically im trying something out and i need to add a partition to my android device thats about 100mb big. Is this possible? the Sdcard wont work as a partition
I've seen it done, but for some reason the OS will repartition it back to what it was before you edited it.
Best route would be to dump your current PIT file (partition table and other info is included in there) and modify it to fit your needs if possible. There are probably other threads on this if you search up "modifying PIT file"
That file can be used to repartition the phone. If you modify it correctly you should be able to resize other partitions and use that extra space to create your own XXX mb partition.
You need to use heimdall but there are existing ones out there depending on what size your internal storage is
16 gb or 32?
