[Sony Tablet S] qz8s05:
prev version[120410004] is larger than post version[111104049]

Hi Guys,

Great tool (Thanks condi) and a great thread (Thanks everyone).

I used the tool initially to go from UK 3.2.1 to US ICS as per the tutorials, on my 16GB Wi-fi only device. Now I've gone back to 3.2.1 which is where I started to experience problems.

I'm able to root my device, change region etc, but when it comes to re-flashing using _hack_recovery.zip, I get the 'E:Prohibit update as a result of checking version or base sku' error, due to 'prev version[120410004] is larger than post version[111104049]'

UK Sony Tablet S, 16GB, Wi-fi only.

I have read quite a large chunk of this thread, but my lack of skill set has lead me to post. Any help would be appreciated.

Thanks
