I know downloading the files is painfully slow on phoenix.
if you dont have a 1.3 firmware for your original code then I would try the german 1.3. it depends if you want go with LTA or german is up to you..it were me I would try the upgrade from 1.2 to 1.3.
after you get the downloads
for phoenix: w/ phone swd off and NOT connected
file open product select rm-696
select flashing click product code uncheck detect prod automatically,select your firmware and then click ok.
click deadphone flashing.
w/ phone off plug into usb, may have to wait for phoenix usb drivers loading??
click refurbish.
good luck
if the above doesnt work, try again with your original firmware from sim tray.
post your progress.
