Well, this is a not so good tutorial because i´m new to android and can´t get to undestand perfectly how it works. It worked for me, not respond if doesn´t to you, your risk. Should work for any infotmic based. You need a micro sd. 1.Firstable, download firmware Index of /soft/tablet/9inch/DualCore Download Formatting & installing from where it´s shown here http://www.androidtablets.net/forum...fotmic-it900-tablet-boot-loop.html#post303785 Extract OEM_it900_v1.9 2. Open IUW.exe inside zip iuw_2.0.15a_beta.......... FILE/new/new ius ius template:android nand ( not sure 100% marked this...) select folder of the extracted firmware wrap 3. Get a microSD, connect to pc DISK/make burn disk select microsd mark install bootloader, select uboot0 and uboot1 in the extracted firm MAKE (this formats sd, use a empty one or save) 4. Insert microsd in tablet and power on. once finished will say to take sd off and voilá! I have to say that i´m not sure if i´ve changed firm or not, I dont know actually anything, at first sight can´t see differences in ROM. but i have my tablet working. Hope helps someone. NEW INSTALLATION, ALL DATA LOST.
