Apparently the T400s is supported, according to https://tehnoetic.com/tet-t400s
Not quite yet, different machine made and designed by different company (shinai-mv, by lenovo) than t400 (malibu-3, by USI). You can crossflash for now, for limited support
Also has WSON8 which needs to be replaced, which requires a bit more skill and being cautious of surroundings, unlike on x200s/t
Swift Geek, are you saying that the flash chip needs to be de-soldered from the motherboard in order to flash it?
Needs to be changed to SOIC8, just like on x200s/t
Would it be possible to mention on the main site that a soldering step is required to flash LibreBoot on a T400s? This might serve as a useful warning to people who don't have soldering skills yet but are interested in flashing their T400s.
It's a whole different device, new page needs to be written for it. Patches welcome
I have successfully been able to install Libreboot onto a T400s, and will be adding in some documentation onto the Libreboot website for those looking to try it for themselves.
I bought an old T400s and checked everywhere I could how to use libreboot on it.
First of all : Is your documentation here https://notabug.org/esmith1412/libreboot/src/master/docs/install/t400s_external.md up-to-date ?
Then the big part ;-) :
I read somewhere at https://trisquel.info/en/forum/ that Persmule or Tiberiu from technoethical made/used a patch mentioned here https://lists.gnu.org/archive/html/libreboot-dev/2016-08/msg00027.html incorporated to T400s image (or here ? https://lists.libreplanet.org/archive/html/libreboot/2016-05/msg00017.html), is it needed and could I find it somewhere ?
I saw nothing for T400s in https://libreboot.org documentation wiki even Technoethical said they would help to make some guide (https://trisquel.info/en/forum/technoethical-t400s-now-available?page=2#comment-116477).
I found other informations here https://trisquel.info/en/forum/technoethical-t400s-now-available?page=2#comment-116437 here : https://trisquel.info/en/forum/technoethical-t400s-now-available?page=4#comment-123747 and here about soldering : https://trisquel.info/en/forum/technoethical-t400s-now-available?page=4#comment-123751
--> To sum up (please correct me if I'm wrong) :
SOLUTION 1 :
SOLUTION 2 :
I have never flashed a chip, and I'm a complete noob at libreboot but I like challenges.
Thank you in advance for reading and for giving me some help for the most courageous ones ! ^^
You SHOULD NOT solder wires to wson8 ever unless you care more about flash contents than board. Soldering wires like that is an easy recipe for destroying board (effects of which can be sometimes visible in months time)
Issue tracker is not support page, move to IRC for that
OK thank you for your advice, sorry about the mess ! Could you just tell me what channel @freenode IRC please ? I tried #peers and #notabug but only a bot make answers.
