199 **WARNING! Please follow the guide PRECISELY, if you follow it, but please
200 only follow it if your ThunderBolt is already broken. If it isn't, use
201 Lenovo's software-based updater. If you do the external method, you MUST be
202 very careful; the guide there for example says to disable ThunderBolt assist.
203 It also says to erase first, then flash the `null.bin` (file with zeroes in
204 it), then BOOT, and when it boots, power off and re-connect clip again and
205 then flash the padded TBT.bin - whereas, for example, if you simply flashed
206 a padded TBT.bin and nothing else first, and boot, it will be perma-bricked,
207 in that the CPU won't come out of reset (it'll bootloop). We don't yet know
208 how to recover from this brick scenario. So all of this is to say: flashing
209 the ThunderBolt externally is EXTREMELY HAZARDOUS, and should be done with
210 the UTMOST CARE, ideally NOT AT ALL. -- ALSO: the guide only covers T480,
211 but should be similar on T480s and other ThinkPad models.**

225 **AGAIN: It is extremely easy to permanently brick the ThunderBolt controller,
226 rendering your system completely unbootable, if you use the external recovery
227 method. If you're still able to fix it with a software-based flasher like the
228 one Lenovo provides, please use that at all - or simply don't fix it at all,
229 because the machine will at least still charge while it has the ThunderBolt
230 issue, where older firmware is used.**
