My tips comes from 3 librebooted X200s I’ve done (plus 1 fried due to user error by me):
your most important tool is a heatgun with smallest possible nossle (or is it nozzle?)
replace the stock WSON-8 nightmare chip with 8 mbit SOIC-8 chip
take a photo of red dot on the WSON-8 before heating it, it shows you the right position/angle/side for the SOIC-8 chip too
be aware that the whole bottom part (i.e. big area) of that nightmare WSON-8 stock chip is soldered
do not compile libreboot with raspberry pi nor any sbc you’re using (use real x86 computer)
when flashing, use slower spispeed than you’d use with Coreboot (older machine)
soldering the SOIC-8 chip do not require any skills nor good vision (super easy task)
With a good and especially small nossled heatgun you don’t need to cover the motherboard at all. If you melt the plastc top cover of the WSON-8, it doesn’t mind but not necessary either. Just don’t melt the motherboard (small nossle!!!) and you’re all good. Use tweezers rather than pliers, because force is bad and when the super-high quality soldering tin is melted completely, the WSON-8 chip comes off even if you just blow on it.
Flash the 8 mbit SOIC-8 before soldering it onto the motherboard.
I have no lots of soldering skills/experience, but it is fairly easy task if you just have the small nossled heatgun.
And oh yeah, some guides suggests to solder jumpwires onto the stock WSON-8 chip rather than heating it off, but that approach was way too hard for my soldering skills even with the smallest possible tip on my Pinecil soldering iron.
I never thought to get this detail answer from lemmy user. You are real dark magician! Thank you so much… I just surprised when check my inbox and got this + easy to understand for inexperience like me in Libreboot process. The only info I have right now for L-booting x200s is this. But your tips here are clearly make L-booting x200s looks so easy and make it possible as fast as I can.
do not compile libreboot with raspberry pi nor any sbc you’re using (use real x86 computer)
Can you give me an example for what real x86 computer you used or other best option? I’m still confused for the keyword in search engine. Still… thank you so much for this guidance from my soul. It looks like overreacted, but this little step stone is very important for me to start…
So any computer or laptop which you have will work just fine. No matter how old it it is.
You can also compile the rom with RasPi but for some unknown reason it caused me unworking rom even it didn’t give aby errors. I contacted the developer and he said I should never compile anything with RasPi :D
So I still need Beaglebone Black, connect it with x86 based laptop, and run the script on x86 laptop right? As the standard requirement for L-booting I read in official guide…
Gladly, I don’t have and don’t wanna buy RasPi because the price is insane in my country (Indonesian), but other peripherals like BB are still on normal price. Have you any recommended using other alternatives than Beaglebone Black? :)
I’m sorry to ask many noob questions to you, because I just found the one who make this possibly happen as I’m starting losing hope for tinkering this, and don’t wanna risk to brick that too cause my poor knowledge and preparing things. Still… bless you sir…

I’m glad my answer satisfied you :)
