I've having nightmares with this i have the same problem but i'm just starting, i have basically no idea of the procedure can any body pleas describe step by step how to get to /boot/ directory, is it over Debian on the tinker boad, is it on the sd card over windows (it can only read 1 partition with no such directory), is it over terminal in windows using adb? or terminal in debian os? if so how do i extract (code) the file so i can push the new one?

i jus got it, for all noobs like me her it goes my explanation

1) get the files and putt them in a safe location in your main pc each pair in ther own folder
2) remove the sd card frome the TKB and insert it into a adapter for the pc, the pc if you are using windows, will detect 2 partition, just open the one that look normal and can be opened, now CONGRATS YOU ARE IN /ROOT/ DIRECTORY heres where the files must be replaced
3)copy a back up to your main pc, of all whats in this folder, the root folder
4) in case you whant to rotate the screen 180 degree, go to your main pc and open the folder in which you saved "rk3288-miniarm.dtb_rpi7_touchscreen_rotate_180" make a copy of it and rename it as "rk3288-miniarm.dtb".
5) also rename the file named "zImage_rpi7_touchscreen_rotate_180" and rename it as "zImage"
6) now copy bouth renamed files into /root/ and replace them with no fear, cause you allredy have a back up of all /root/ directory saved in your pc.
7) now make sure you allredy downloaded the files to fix wifi, (the correct one named modules.tar.gz) and het it into a working usb.
8) now take the sd card with the new files in it and insert it to the TKB (tinker board) and power on, now your screeen ant touch screen may be rotated 180 degrees, so turn your TKB 180 degree and insert the usb with the correct wifi fix files
9) coppy them to what ever directory you whant, in my case it was a folder called "wifi fix" into the documents folder.
10) click on to the "starte button" (bottom left) scroll to system tools and then click to "LXTerminal"
12) now navigate to the folder where you saved the fix wifi files (i dindt knew that spaces in betwen folders had to be represented with a dash /, so if you have any trouble go to cd /home/linaro/Documents/ and then execute dir to see folders with in and copy the name and open ir with cd such as...)

linaro@TINKER:~$ cd /home/linaro/Documents/
linaro@TINKER:~/Documents$ dir
Scratch\ Projects rotar\ la\ pantalla\ tinker
chromium\ downgrade screen\ rotation\ final virtualkeyboard
linaro@TINKER:~/Documents$ cd screen\ rotation\ final
linaro@TINKER:~/Documents/screen rotation final$ dir
ROTATE\ 7INCH\ SCREEN.txt rotate\ 0 rotate\ 180 wifi\ fix
linaro@TINKER:~/Documents/screen rotation final$ cd wifi\ fix
linaro@TINKER:~/Documents/screen rotation final/wifi fix$

13) now you sould be in the folder where "modules.tar.gz" file is so all you nit to do is one by one imput this comands

$ sudo rm -rf /lib/modules
$ cp modules.tar.gz ~/
$ sudo tar zxvf ~/modules.tar.gz -C /

14) the first two may apear not to do anything but if no code apears it means they ok, the last one should show bunch of text so wait for it to finish doing its thing
15) now imput
sudo reboot

16) once the tinker board has finished rebooting tinker os may pop up a bubble saying there are networks available. so you are all set.

this is just a summery for all us, noobs that havent work with linux
so
thank you all (the comunity) fot this post and all the work putted into the kernerl modding that made it posible for us noobs to execute all the tinking you mor experience guys had share wit us.
