I've seen kemod's successful mod on a X230t but I don't have the soldering skills
https://www.bios-mods.com/forum/Thread-TUTORIAL-Lenovo-X230-Tablet-BIOS-Whitelist-Removal-Hardware-Flash
I've seen mhaedo(from whom I copied most of his request post) tried to do this with a clip but failed
https://www.bios-mods.com/forum/Thread-REQUEST-Thinkpad-X230-Whitelist-Removal--18404
there is an article about this on coreboot wiki so the clip should work
http://www.coreboot.org/Board:lenovo/x230
I'm guessing mhaedo failed because he did not provide separate 3.3V power
and I do have some questions to ask:
1, if the whitelist is removed, do I have to use Wi-Fi adapters from Lenovo with FRU label or any generic Wi-Fi adapters(like the gigabyte branded 7260) will work? I don't care if the hardware wireless switch doesn't work.
2, again, will broadcom adapters work? I want this because 7260 is only 2x2 MIMO, there are broadcom 3x3 MIMO adapters, and maybe I'll try a Hackingtosh mod later.
3, I have not ordered the adapter yet so suggestions are welcomed.
4, I know TPM module must be disabled, but are there any other consequences beside this?
5, some Wi-Fi adapters like 7260 comes with bluetooth integrated, I assume I should remove the old bluetooth module after this, again are there any other consequences?
as of now (2015-04-16) I'm waiting for the SOP8 clip and spare MX25L3206E, I'll update my progress, thank you all for reading this long post
