This demo I want to locate and extract my recovery.img, boot.img, system.img
1. type from your command window
3. From your device using a root explorer app navigate to /dev/block/platform/ and navigate to the folder that will contain a folder with "by-name"
4. Once you get the location of "by-name" folder simply follow the sequence of folder location
5. Depending on how many sub folders before you reach the "by-name" folder use this code for your adb command
6. From your command window type the following after you already know the location, for this sample "by-name" folder was found under folder 7824900.sdhci and the latter under soc.0 folder
now type the following:
7. The following list will show and just search which mmcblock your IMG needed is located
for boot.img located at mmcblk0p37
8. Your recovery.img and system.img located at mmcblkp38 & mmcblkp45 respectively. You can now extract with this command:
cat /dev/block/mmcblk(#)> /sdcard/(name-of-img).img
sample only:
9. Navigate to your sdcard and you will see the extracted img that I typed as "recovery_pull.img"
