[REQUEST] Tweak Flash Version on N9 - maemo.org

Win7Mac · #1 2013-06-20, 16:45

Flash 10.1. just won't do it anymore on many sites.
I wonder if somebody already came across an equivalent of tweakflash for the N9? - Like this for N900.

Or at least how to do it manually?

Following this instruction, I searched for libflashplayer.so and found it in /opt/adobe-flashplayer/libflashplayer.so.
Now when I search for "31302e31" in a hexeditor, I can't find that number. I guess it differs from N900. Any help?

I think this file is the firefox not for stock browser.I wish , however, to find someone a solution.

OK, here's something that might work, but is prone to render your device MALF (need to reflash), because of aegis file protection:

Code:

sed -i 's/10_1_105_6/11_*_***_*/' /opt/adobe-flashplayer/libflashplayer.so

You could of course copy that file to PC, open it with a hexeditor, search for "10_1_105_6" and edit to a higher value. Make sure to only overwrite characters and not change the file length.
Actual version on N9 is 10.1.105.6, not sure which higher versions might work, here's a list: http://helpx.adobe.com/flash-player/...-versions.html

EDIT: Some furter info I gathered on IRC:
After editing, refhashlist has to be re-signed. There is even a refhashlist.pl perl script somewhere on the forum that could do the magic for you if your not that familiar with aegis magic.
Basicly after edit, you just take sha1sum of the new library, update the checksum in refhashlist file and then resign the refhashlist to avoid malf.

Would this work? Anybody willing to test?

Or, decompress the deb file, make the change in libflashplayer.so, and re-create the deb file ?

I pm'ed ladoga about it and here's what he said:

For a quick test I just moved libflashplayer.so to another filename on my main n9 and the phone works just fine. Exited shell and then renamed it back without any issues in normal devel-su root. If you tried to do that to an aegis protected system file (for example /etc/init.d/rcS) the file would be locked and you'd have to disable aegis validation with aegisctl before you could rename it back. (and yes you'd need to update refhashlist if the file was changed.)

My suggestion is to simply take backup of the library in case hexediting goes wrong:

Code:

# cp /opt/adobe-flashplayer/libflashplayer.so /opt/adobe-flashplayer/libflashplayer.so.bak

and then replace the original file with a one that has modified flash version string in it.

thedead1440, feeling adventurous?

Just checked my refhashlist:

Code:

adobe-flashplayer R 39 opt/adobe-flashplayer/libflashplayer.so
S 15 com.nokia.maemo H 40 b38e7706479854fdc9b047bbfcb20deb96007b6b A 0 0 33261 P 6
