but flash tool still recognize it right?
then you still can re flash the stock ROM to your device, as far as i know error 4032 is because the ROM file is not suitable with your device. try flash using old ROM file
try this one http://www.techulk.com/2014/01/sp-tools-dram-error-fixed-finally-heya.html

6. Unplugged your phone again and load a850 127 ROW scatter file this time. Make sure that the PRELOADER BOX is untick/uncheck to avoid messing your PRELOADER again.

Reply to  jimmypiu

as far i know error 8038 can be solve with pressing upgrade button, and 8038 is because scatter file not fit with device partition. and you right upgrade button cannot be click when not all box is ticked, so maybe try to tick all box then press upgrade after all you already know how to repair messing preloader right?
