===== Introduction =====

In order to extract all data properly from an SD card with Docomo content, we need some keys located in a hidden partition of the card, detectable only by some specific SD card readers.

===== Methods =====
Preliminary Steps

  - [[#Verify Compatibility of SD Card Reader]]

Extraction Tools
  - [[#CPRMTool.exe]]

==== Verify Compatibility of SD Card Reader ====
  - Open the “Device Manager”.
  - The SD reader details can be found either under the "Memory Technology Devices" or "Universal Serial Bus controllers".
  - Select the device you want to investigate: if you’re looking under USB controllers then you should look for a “Realtek USB 2.0 Card Reader”. If you are instead looking for the device under “Memory Technology Devices” you will have to look for a “Realtek PCIE CardReader”.
  - Right click the device and select the “Properties” option like in the image on the right.
  - Select the “Details” option, then in the window with the arrow, select “Hardware IDs”
  - If the values written in the window below are either one of these 3 then your device is compatible.<code>VID_0BDA&PID_0129
VID_0BDA&PID_0139
VID_0BDA&PID_0140</code>
  - Now that you know if your device is compatible, we can proceed with dumping the SD contents.

==== CPRMTool.exe ====

  - Install [[https://download.lenovo.com/consumer/mobiles/hpse03ww.exe|this driver]] if not installed already, open the file and complete the installation. 
  - Install the CPRMTool.exe, available [[https://deltacxx.insomnia247.nl/uploads/CPRMTool.exe|here]].
  - Insert the SD card in the driver
  - Open your computer terminal AS ADMINISTRATOR{{ :phones:docomo:2025-04-03_16_12_14-administrator_command_prompt.png?600|}}
  - Lookup the path to the SD card block device using the following command:<code>wmic diskdrive list brief</code> You need one corresponding to the SD card, starting with this line<code>\\.\PHYSICALDRIVE</code>You need to get the DeviceID corresponding to the SD card, save this somewhere, as you will use it soon.
  - Now change your current directory to the one where the CPRMTool.exe is located (if you just downloaded it you should probably just use the cd Downloads command).
  - Now run these commands, but change the \\.\PHYSICALDRIVE1 part down below with the DeviceID you found before.<code>.\CPRMTool.exe -dumpmid -card \\.\PHYSICALDRIVE1 -mkbid 11 -out mid.bin
.\CPRMTool.exe -dumpmkb -card \\.\PHYSICALDRIVE1 -mkbid 11 -out mkb11.bin
.\CPRMTool.exe -dumppa -card \\.\PHYSICALDRIVE1 -mkbid 11 -out pa.bin -skout pa_sk.bin</code>


NOTE: if the last command ends up with an error after reading a good bunch of sectors - that's normal.
