By selecting related module items and clicking the 'Update' button, LSTC tool will download latest U1 package,
Diagnostic tools and other useful tools as BIOS tool, panel fireware tool, etc. and get them deployed
in USB key for later usage.
LSTC tool will get itself deployed into the USB, please go check LSTC utility in USB sub folder: 'LSTC_TOOL'.
the suggested size of USB stick to install minimal and full set of features of LSTC:
** minimal size 4GB: (all tools installed/deployed, but without C1 crisis bios packages).
** full size 9GB:(all tools installed/deployed, with all C1 crisis bios packages).
the package cache feature of LSTC(and C1 tool):
** All packages will be cached in an cache sub folders of LSTC, while another USB is connected,
LSTC will check the cached package’s version information and deploy from the cache folders if the version no issues,
instead of downloading it from server side each times.
So, it is better to run LSTC on your working unit's hard drive side, instead of running it in USB.
Anyway, 2 USB scenario also will work.
** for C1, if you want to get C1 crisis packages cached for deploying to other USB, need:
--> run LSTC w/o USB-->click and running C1 inside LSTC w/o USB -->
once C1 launched-->plugin target USB --> start C1 Update
Why need to format the USB key/device via the LSTC format button:
** If you do not format your USB key as required by the provided 'format tool', the ThinkPad Maintenance Utility will
enter "Read Only" mode and you can view, but cannot change anything.
the error message will like: TpReadEEPROMBlock : Write access to Block#84 is denied...
Not all connected USB key/device are recognized/accepted:
only Removable USB device can be supported by LSTC tool, as it is ThinkPad Maintenance Utility 's limitation.
Refer to figure:
Update button is gray and not work:
LSTC tool could launch without network connection, related Update feature will be disabled,
once network is connected, need to launch LSTC tool again to enable the Update button.
also, an connected USB key is required the same.

A: U1 has related Windows PE booting feature provided, but as limitation as we can not provide/deliver any Windows PE image with U1 package and LSTC,
service engineer need to provide Windows PE byself --> put it in proper subfolder inside U1 USB & rename the Windows PE image as required,
Then, we can boot related Windows PE via U1 's boot menu items directly under EFI shell
Notice for using this WinPE boot entry:

A: U1 tool related USB key need to be formatted by provided formatting feature inside LSTC or U1 update utility, this is required by ThinkPad Maintenance Utility. thus, issue reported as some particular USB key brand formatted by LSTC/U1 Utility will have this issue on particular products
Suggestion go standard technical escalation to get help from L2 and related Product RD team
So far, the only workaround from U1 side is format the USB key by other common third part formatting utility to FAT32 format, then, use U1 utility or LSTC to update / deploy U1 modules to the USB, thus, the USB and U1 will able to work on that particular product, but the ThinkPad Maintenace Utility will not work anymore on any ThinkPad(suggest to create a new USB only for products with this issue)
