Here are some OTA firmware updates which were decrypted, they are fully working and can be installed using the original recovery
Huge thanks to Condi who actually made this possible.

You can check which region/product you have by looking at your build.prop:
Code:
ro.build.description=nbx03_010-user 3.2.1 THMAS0042 0042.004 release-keys
Please look at the next post to see what those numbers mean.


Full OTA:

signed_nbx03_007-ota-0042.017_decrypted.zip

Incremental OTA:
incremental_nbx03_001 0042.001

It would be very helpful, if you would describe the version exactly.
From which country, which version and with or without 3G.
Otherwise it is a risk to flash a "unknown" version.

We should also collect a "region code translation table"
I would like to start with:

Region Code:
001 = USA
007 = Germany
015 = Austria
016 = Poland

Version Code:
0042.017 = 3.2.1R2
11000.014 = 3.2

I have two different versions downloaded:
signed-nbx03_007-ota-0042.017.zip
signed-nbx03_007-ota-11000.014.zip

My device:
Sony Tablet S - 16GB - no 3G - Model: SGPT111DE/S

Could someone explain how we can decrypt a firmware version?

Yes, more details needed, we cannot do a blind update.

Actually my post was intended to be used by developers, there are some interesting technical information in the update.

I'll try to upload more firmwares once i have time and try to put a list like obicom suggested

Great work! Is there anyway you can create an update.zip to replace the /system/sbin, /system/bin, and /system/xbin with the stock or prerooted files?
I ask this because, I tried creating one, but I still get the signature verification failed error.
I have tried signing it with a few different methods, but still failing.
I'm trying to root the device and when I do, I get permission denied with every buysbox command, ie chmod, insmod, etc...
In addittion, I tried running just the update, and that failed because it is the same as my current version. I would think you could just change the update version inbedded in this package...

@Condi:
If I take a look into the posted fw .. I am a little bit astonished.

I found three different region.prop files:
one for Austria
one for Switzerland
one for Poland

Does it mean this is the fw file for this three countries?
Do you know what the last three digits of the file name mean?

for Poland 004 and in Germany 017?
Mabay a hint for the included kernel version? (Build)

Is this for wifi or 3g version? Or maybe desn't matter. I ask because I have SGPT111PL/S and the last ota I got 3 days ago was:
signed-nbx03_015-ota-0042.002.zip
