Help, partially flashed dutch 44.30409 firmware? Now I don't have sound anymore.

[KRiZ]

Hello, I have a bit of a problem
After an update of Explora to version 44.30409, I tried to revert back to 26.30409.
But it seems that now I have only partly flashed the firmware and now I am stuck on version 44.30409 and I have no sound anymore (probably due to partly flashed 26.30409)

Can anybody help me making the complete 44.30409 version flashable, so my sound will work again.
And maybe it can be hacked also

All I have is a ugdx file, but I can't seem to understand how to make ik flashable (I'm no Linux expert)
The file is on my dropbox: NL_dut_12681_9FB338E9C2D94C2B161091D26E51AEF7_inno_NLdut_1368_kb44_bu1365474482_20140114-152741.rar

I would really appreciate if someone could help me, also my almost 3 year old son would be really glad!

http://spiffy360.com/forum/thread-956.html you can follow this to get the various firmware parts out of the UDGX file. trying to revert back to an old firmware is a bad idea because when you do an update, it updates more then just the firmware portion. It may also update the rootfs, system and bundle partitions. I am not sure if system and bundle are part of the firmware, but I know the rootfs is not so there may be some incompatibility between the firmware and rootfs if you flash a different one. This is why it is not a good idea to flash anything besides what the current version is on your tablet.

Great, thanks, so far I have done everything like your tutorial. Just the HEX value was a bit diffrent, but it was at the same offset, so I continued with that.
I have extracted the files, that went fine.

Now is the question: can I just flash the unextracted files?
And to wich partition should they be flashed?
system to: sdcarda6 or sdcarda7? I guess the system is the problem in my case.

Thank you for your help!

I'd have to actually run mount on a device to see what gets mounted to what places to tell you for sure. When you went to flash an older version, did the script not make a backup of your current firmware which would have been the newer one? It should have unless you just manually flashed it.
