i've got the same kit / problem - the plexiglas hinges shown in the clips are not preset in the package.
be careful with the connectors, etc as they are fragile
this is what i've done until now ( can't add a photo as i've left it at home)
- solder the headers on the board edge - optional if you don't want to use the peripherals
- cover the back of the lcd with some insulating tape, be careful to leave the entire lcd flexible pcb clear - lift it at 90 degrees and put the tape under it
- fold the lcd flexible pcb on the back of the panel - it's natural position and then with a thin strip of tape i've stuck down the wide portion of the flex - the one that has some SMD parts on it, so that the portion that has the connectors is free to move
- connect the lcd flex to the board: lift the black latch of the connector and insert the flex with the exposed copper towards the board, be sure that it's inserted all the way and it's straight then push down the black latch. try to press on the entire latch at once - it will click into place
- burn the uSD card the way it's described on https://licheepizero.us/
- insert the uSD and connect it to the PC via tre micro-usb port
the board should power up and light the display - you will see the uBoot logo for a while and then depending on the image you selected it will drop to a shell or a debian login
where i'm stuck now : i don't see any activity on the 2 serial lines even if i can login on the shell
i'll dig into that once i get back to the board.
The "laptop" will not work properly because there is no VBAT to 5V booster present.
The board itself will work if powered by the battery but you'll have the battery voltage on the 5V rail so no USB device attached will work.
extra things i did:
- added straight header pins for the wifi board
- added straight header pins for the 5V and 3V headers
- added 90 deg pins for all the other connectors
- stuck the board to the back of the lcd with some hot-glue
- stuck a USB-SERIAL TTL next to the board (3.3V interface )
- connected he 5V, GND, RX, TX lines to the board so it should provide power and a serial interface
