== Description ==
The TOC is a partition table found inside the modem firmware of various Samsung
Smartphones and tablets running Android.
That partition table has information like the name of the partition and its
size. Thanks to a blog post by by Tony Garnock-Jones[1], we now know the
name of that partition table as in the Galaxy S7 (herolte), there is an entry
for the modem partition table itself in the modem partition table:
00000000: 544f 4300 0000 0000 0000 0000 0000 0000 TOC.............

Here we can clearly see here that the first partition ia named TOC. This dump
comes from Tony's blog post.
More information seem to be added over time:
- On devices like the Galaxy Nexus (GT-I9250) or the Galaxy SII (GT-I9100),
the TOC partition table doesn't seem to exist as the first partition starts
at the offset 0.
- On devices like the Galaxy SIII (GT-I9100), the TOC partition table doesn't
have an entry for itself.

== Devices without a partition table ==
The following devices don't seem to have a partition table as the first
partition starts at the offset 0:
- Galaxy S (GT-I9000)
- Galaxy SII (GT-I9100)
- Galaxy Note (GT-N7000)
- Galaxy Nexus (GT-I9250)
- Nexus S (GT-I9020, GT-I9020A, GT-I9023)
== Thanks ==
Before Tony Garnock-Jones's blog post, we had much more partial information on
this partition table.
