The development on cheaper, lesser known tablets has been surprisingly active in recent weeks, and Matsunichi’s modest 9.7″ tablet is no exception.
The duo doesn’t have ICS or CM9 working just yet. However, with updates on their progress appearing every 1 or 2 days, it is only a matter of time before they get an alpha for users to test. The latest update on their progress:
With chinabull’s help, I found out how to generate the 20 bytes SHA1 checksum for trhe images contained in the firmware.
It is the SHA1 checksum of the image + the ‘cafeefac’ trailer + the length of the image (including the ‘cafeefac’ trailer).
I updated the C program ‘unpacker.c’ to also compute and check the SHA1 checksum.
The program can be compiled with the following command:
gcc -O -Wall -o unpacker unpacker.c -lz -lcrypto
There’s a load of technical jargon in there, but it all adds up to one thing: they are getting closer every day.
For those who own the tablet who want to keep tabs on the progress or be potential testers when a release is finally up, you can find all the information you need in the original thread.
