I found t410 board challenging for me also since yes Im also inept with a hot iron. After doing some reading and being directed to other github threads, I found this helpful https://www.coreboot.org/Board:lenovo/x201 since the x201 and t410 share similar specs, I was able to flash coreboot onto chip with "ch431a programmer at 3.3v" and boot. Unfortunately I was unable to get coreboot bios and me_cleaner to work together (manually and/or through "make nconfig" script). If anyone was able get both working happily W/O soldering I'd very much appreciate some insight.
Now this wasn't like other coreboot install on my x230. AND POWER WAS MY ISSUE in reading and flash write to chip(had to learn hard way) and I wasn't too much concerned in the end w/ damaging board. So I can't say if the method I chose was safe or even reliable, I've done limited testing, but I was able to boot into stock linux OS and list devices. In the end I stayed w/ a stock/me_clean'd bios - WIfi card wasn't listed in lspci w/ coreboot bios =(
Person in previous post - Peter Stuge - seems to know a great deal about this project and by no means do I feel his advise isn't sound or valid so.... hope this is helpful.
