Normally i'd agree that with statement at least in a very general sense. However in Fa_Piter's particular case he already had V5.80 bootloader and x-loader flashed to his device so it was in fact quite safe to load a non-patched (original) 14.bin from V5.90 (albeit one dumped from device). A region-patched fw_all.bin from actual V5.80 fw also using it's own boot.bin/ldr.bin to flash is quite safe too. Both methods carry only a very slight risk imo.
