updating to pr1.3 caused me the hell lots of trouble. Neverthless, i snaged out pr1.3 combined.bin from tablets.dev and reflashed, BUT didn't stop here i also reflashed vanilla emmc too. I lost that updating pain in the ****. This justifies things, I discovered the easiest way of updating :P.
P.S. I even didn't backup my data before reflashing. don't care tho
