Victory! We have been able to root the Toshiba Excite Pro (Toshiba AT10LE-A-108) with a Dirty Cow enabled KingoRoot.
Dumping recovery (SOS partition) was successful. Partitions info of this tablet and their names is available too. We managed to instal the Device Info HW app by Audrey Efremov and select the Info Center option to upload device information (components) to the database.
The next step was to find Toshiba Excite Pro clones for donor parts (needed for ROM development).
Asus Transformer Pad TF701T (KOOC), Asus Google Nexus 7 and HP SlateBook 10 x2 PC were the devices selected for donor parts.
