That’s how users lose their ability to recover the system firmware when flashing mods and no backup done…it’s a common mistake assuming a mod will work straight forward and have nothing to worry or care for an asset…

CH341 are the cheaper ones…for future and multiple flash a better one is recommended, plenty out there on the web.
That’s all from me, good luck.
