Online Nandroid uses a file named ``partlayout4nandroid`` for detection unmountable/unmounted partitions such as boot and recovery. This is a guide of how to make the ``partlayout4nandroid`` file for various devices.
|
|
|
|
|
|
|
|
1. The file should be in text format.
|
|
|
|
2. The raw file should be named ``partlayout4nandroid.{codename}`` where {codename} is the device's code name. Eg: ``partlayout4nandroid.maguro`` for Google Galaxy Nexus
|
|
|
|
3. Line endings should be UNIX style, LF only.
|
|
|
|
4. The first line of the file should be a column header in the form ``dev: size erasesize name``. (Spacing does not matter.)
|
|
|
|
5. Each line, thereafter, should start with the partition block device representation, which should be followed by a colon, a space, partition size in hexadecimal, a space, eraze size in hexadecimal, a space and partition name in quotes. An example is shown below:
|
|
|
|
``mmcblk0p1: 1ab3c 70000 "misc"``
|
|
|
|
6. The hexadecimal size and erase size should omit the ``0x`` normally used for hexadecimal representations.
|
|
|
|
7. The hexadecimal size and erase size should be padded with preceding zeros until it is the same length as the hexadecimal size of the partition with the highest size.
|
|
|
|
8. The eraze size can be left as zeros, if unknown, padded in the same manner described above.
|
|
|
|
9. Each partition must have a valid size value.
|
|
|
|
10. If a partition's name is not known, it can be named as ``unknown``
|
|
|
|
11. The file should end with a line feed / empty line.
|
|
|
|
12. The below partitions must be named:
|
|
|
|
* boot partition, named as "boot".
|
|
|
|
* recovery partition, named as "recovery", unless the device does not have one.
|
|
|
|
* system partition, named as "system".
|
|
|
|
* data partition, named as "userdata".
|
|
|
|
* cache partition, named as "cache"
|
|
|
|
* appslog partition, named as "appslog", if the device has one.
|
|
|
|
* wimax partition, named as "wimax", if the device has one.
|
|
|
|
* datadata partition, named as "datadata", if the device has one.
|
|
|
|
* flexrom partition, named as "flexrom", if the device has one.
|
|
|
|
* efs partition, named as "efs", if the device has one.
|
|
|
|
* internal sd card, named as "emmc", if the device has one.
|
|
|
|
* All other mounted / mountable partitions. |
