i think is hardware problem,try to do this method and post the result here.

use setool box. use DKU60 cable. in setool setting click on USE SERVER FOR CSCA UNLOCK/FLASH then back to SONYERICSSON TAB choose the model. click RECOVERY then insert battery and press 2+5 then the DKU60 cable.
remember post the result.................

hope is not hardware problem, good luck.........!!!

THE SOLUTION IS TRUE AND IT DOES WORK ON SOME MOBILE SOME TIMES BUT NOT ALWAYS IN HUNDREDS MAY BE FOUR TO FIVE but it is a good solution so is the way to short circuit the backup battery but there are some which doesnot connect to the software is there any solution for that
