I have now rebuilt my own Firmware from the output of this utility, and successfully loaded it in the Android Firmware I created and am currently working on using the Kernel I made from the SDK, and a Driver I had found that loads the firmware directly from a file. I will now begin to modify the driver sources to work similarly and load the firmware directly from a text based file as does the driver I located ( this driver came from an N821 Tablet Firmware). In order to make the output work I had to do some comparisons to the driver supplied firmware.h files until I located several that were extremely similar. I also did multiple pulls of the running tab firmware and did comparisons between them. The pulled firmwares did have differences on each instance it was pulled, I took those to be in memory pages used for something other than the static firmware and pretty much just removed all of the variable sections. Using the firmware.h file compares I used the 2 most similar ones and did some edits to reorder the data to the same order used in the firmware.h files, then in sections present in All of the firmware.h files but not present in the pulled data I simply inserted the data from the ones most similar (all seemed to use the same data with 2 variants thus my 2 file setups). Both outputs worked with minor differences and I now have a fully functional Firmware rebuild. I will next compile the SDK supplied driver using my rebuilt firmware and test that then begin modifications to make the driver load the Firmware from a file. If I am successful I would like to package your utility Giving Proper Credits) with the Final Rom I produce in order to allow users to pull the data from their own Stock tab for use with the driver. This Rom will be intended to work on many Tablet models with minor patching which is the reason I have spent so much effort making this Driver .

That did the trick, it read just fine and the output is in a form I am pretty sure I can work with and finally be able to make a driver for this tab that will run with a Kernel Other than the iNet Provided ones. Your work on this is Truly appreciated. If I do manage to get an Android driver that accepts files similar to the output of your extractor as loadable firmware I will be happy to share the sources. It will most certainly end up on my Github account, but if there is any interest in it let me know.

I have compiled and tried the tool but am having a bit of difficulty getting any output. I am not sure I am entering the parameter for the Device correctly... exactly what is it looking for here ? the i2c device name ? I get "Cant open device error" on all that I have attempted thus far. I am attempting to make an android driver for my Touchscreen on an A31s Q711C_2M_PG iNet board. This seems to be a bit of an out of the ordinary driver and I have been completely unable to obtain any source code for it, although I have a Large number of sources that I have downloaded from many places. In any case I would like to make something similar to the sunxi-gslx680 and Rastersoft drivers for Android ie ability to load firmwares from a file. I have not yet tried to compile the Rastersoft version and my attempts to alter the driver included with the A31SDK's have been unfruitful for this Tablet so far. I used the firmware extractor from sunxi-gslx680 however i have not been able to do much of anything with the resulting file due mainly to my Lack of any recent experience in C programming and the differences in sunxi and sdk kernel code.
