Hi Sir. Error 4032 occurs when the preloader is flashed. This is why we always recommended against flashing that file. At this stage, you will need to open the tablet's back cover and look up a board ID that will look something like: ELINK-C706D-v2.2
It will likely not be exactly as the one above but the format will be similar. The reply below with the board ID and I should try and assist further.
