Well, there's this guy on XDA who has figured out how to extract bin and tot files. The structure of the tots and bins are different for each phone. But I got the information for xonar_ to add support for this phone and the tool will now extract tots for: MS770 LW770 MS870 VS870 Thread: http://forum.xda-developers.com/showthread.php?t=1879915 Compiled exe for windows: http://forum.xda-developers.com/showpost.php?p=39745676&postcount=127 Compiled Linux script: http://forum.xda-developers.com/showpost.php?p=39761727&postcount=130 How to use: Open cmd or terminal type Code (Text): Binextractor -ebh "file name" Binextractor -extract "file name" y y That's it. Just wait and all the partitions will extract. To open system.img either mount it with linux or use ext2explore for windows. Thanks to: xonar_ (for making this and providing the source to compile) interloper (for linux version) Wait!!!!!!!!!! I'm not done....continued on post 2. You must be wondering how to get the tot file...right?
