[Sony Tablet S] qz8s05:
Sorry condi, I'm really not getting this :(

When I update to _hack_recovery.zip I'm still receiving 'E:Prohibit update as a result of version or base sku'.

Running adb shell "/system/bin/tempsu -c '/system/xbin/busybox rm /tmp/prev_vendor'" after that simply results in failed: No such file or directory (2) -, although adb ls /tmp/ shows the 'prev_vendor' file.

I'm too used to Micro$oft I think!

Any further help would be greatly appreciated.
