so grateful to you for this patcher! I could successfully unlock the dell3440 I bought locked! the chip I patched was xmc 25rh256cxin, I used ch341b which appeared to not require 5-3.3v mod as it showed to me 3.3v on all data pins. The chip was low profile wson8 so I had to use hot air gun and solder it right on the back of my ch341b. I used NeoProgrammer V2.2.0.10 with selected configuration for chip W25Q256FV as per https://www.badcaps.net/forum/troubl...mc-25rh256cxiq...

kubat thanks a lot for the tip - I was able to successfully read my xmc25rh256cxin
