# DumpFlash DumpFlash is a tool to retrieve and write Flash data to the physical NAND Flash memory or virtual image file. Various operations like ECC check and on-image pattern recognition, extraction and rewriting for u-Boot bootloader and JFFS2 file system are supported. --- ## Prerequisites ### libusb-1.0 http://zadig.akeo.ie/ ### PyUSB * pip install pyusb ### pyftdi * Use one of the following options. * Install from source https://github.com/eblot/pyftdi * pip install pyftdi --- ## Install ``` pip install git+https://github.com/ohjeongwook/dumpflash ``` --- ### Upgrade ``` pip install git+https://github.com/ohjeongwook/dumpflash --upgrade ``` --- ## Documentations For more details, please read following: * https://www.blackhat.com/docs/us-14/materials/us-14-Oh-Reverse-Engineering-Flash-Memory-For-Fun-And-Benefit-WP.pdf * https://www.blackhat.com/docs/us-14/materials/us-14-Oh-Reverse-Engineering-Flash-Memory-For-Fun-And-Benefit.pdf * http://recon.cx/2014/slides/Reverse%20Engineering%20Flash%20Memory%20for%20Fun%20And%20Benefit.pdf * Black Hat USA 2014 https://www.youtube.com/watch?v=E8BSnS4-Kpw * Recon 2014 https://www.youtube.com/watch?v=nTPfKT61730 * Updated by O.Kleinecke in March/April 2015 to improve LP-NAND-Chip support. * KNOWN ISSUES : TODO : Add (cleaner!?) OOB/ECC Support for LP-Devices. * TODO : Add create/read BBT functions * Investigate FTDI/Code based malwritten/malread bytes (byte mismatch for read/write after chip erase every 256/256+1/256+2 bytes) ## LICENSE Copyright (c) 2014, Jeong Wook Oh All rights reserved.
