Maybe try the last instead of x79\x79\x79\x79 to become x59\x59\x79\x79 or x79\x79\x59\x59

Can't check it now, because i need 2 numbers from original file. Probably it should be the same length.. Or another number instead 59...

The below is how hex values look like hence why I suggested x59...

Code:

dd=64 64
DD=44 44
mm=6D 6D
MM=4D 4D
yy=79 79
YY=59 59

I could be wrong but the above is what I got from typing into HxD...

Ok, I did a many tests now... Checked the original file etc...
Probably we can't to add more then 3 characters !

Also, maybe we don't need "refhashlist" script, or my phone is crazy after so much tests

I tested a few times without "refhashlist" script and it worked, but it can take a few sec on the first opening of camera.. Just will test it without "refhashlist" script...
Also on the first opening of camera, probably it remember the last string and you will not see the changes in the name of file, just close camera and open it again...
Some variations that we can do:

perl -pi -e 's/\x79\x79\x4d\x4d\x00\x00\x00/\x79\x79\x4d\x4d\x64\x64\x5f/g' /usr/lib/libqcamera.so.1.0.0
121003_0001
(YYMMDD_0001)

perl -pi -e 's/\x79\x79\x4d\x4d\x00\x00\x00/\x64\x64\x4d\x4d\x79\x79\x5f/g' /usr/lib/libqcamera.so.1.0.0
031012_0001
(DDMMYY_0001)

perl -pi -e 's/\x79\x79\x4d\x4d\x00\x00\x00/\x64\x64\x4d\x4d\x4d\x79\x79/g' /usr/lib/libqcamera.so.1.0.0
03Oct120001
(DDMMMYY0001)

perl -pi -e 's/\x79\x79\x4d\x4d\x00\x00\x00/\x79\x79\x4d\x4d\x4d\x64\x64/g' /usr/lib/libqcamera.so.1.0.0
12Oct030001
(YYMMMDD0001)

0001 = number of image

Someone want another combination ?

Schturman,

You wouldn't need refhashlist.pl as this binary doesn't seem to be in refhaslist in the first place

You were signing it without it being present

There isn't enough space for every format. The original format
is YYMM followed by four nul-bytes. But we need at least one
nul-byte for an null terminated string.
Therefore yyyymmdd doesn't work.
0x59 is for the underscore "_"
You'll have to restart the camera application after
modifieng the lib:
killall camera-ui

I tried, without refhashlist.pl, the:

Code:

perl -pi -e 's/\x79\x79\x4d\x4d\x00\x00\x00/\x64\x64\x4d\x4d\x79\x79\x5f/g' /usr/lib/libqcamera.so.1.0.0

for DDMMYY_0001, but it shows me Substitution replacement not terminated at -e line 1

I resolved now, but only after copying the file to the computer and than run that command from terminal of this one. After this, I copied the edited file to phone and from terminal of this one I replaced the original file.. now it works well..
But I don't understand why the command doesn't work from the phone directly
