I got another TV BOX with RK3328 and got he standard LE img into micro SD, the box boots fine and I could watch movies. however, I have some issues with sound, Remote and some time may be once in the movie the video lags for a second. I paid 35eur for the box so I would suggest if you can not boot from SD to change it while you investigate. Iwould not touch the ROM till I got the LE version in the SD with everything working OK.
