Hi guys. Hopefully someone can help me out. In the course of trying new roms, my serial number is no longer on my X5A-G, in spite of being careful not to overwrite it. As a result, I'm having trouble getting the wifi to work. I have read that a number of tablet users have fixed this by flashing the original firmware. I am currently on #157, but every time I re-flash with the FWDN tool, it fails to write the serial number to the device. So I need the original firmware to have a chance of fixing this. If possible, I would like the version of the FWDN tool, lk.rom and NAND Data.fai, that came with this firmware as well, please.
