looking for kernel and tutorial for R4i ver 1,45 revolution ds blue card (ndsiLL net)

Those R4 clones... Always problems with finding the kernel.

Can't do more for you than linking to the GBAtemp wiki:
https://wiki.gbatemp.net/wiki/Ultimate_Flashcart_Download_Index#R4i_NDSill

There is a download link and it still works. Maybe it's the correct kernel - no idea.

 

For me the best solution is this:
This is not your official kernel (but it is updated and works well), and it's the best you can put today, read here:
https://gbatemp.net/threads/retrogamefan-updates-releases.267243/
It's easy, you need to use the files in the folder DSTT/i
(TTMenu/YSMenu they're both fine, copy one or the other, not together).
For your Blue R4i Revolution v1.45 - ndsiLL.net : Rename 1 copy of TTMenu.dat to iLL.iL

 

Copy only the contents of one of the 2 folders (not both) attached
(they are 2 folders and 2 files)
(between the 2 only changes the graphics, the compatibility with the games is the same)

 

Do not copy the whole folder, I've only said its contents, that's all you have to do.

 

Correct:

Now try to start the card

 

Try formatting the micro with SD Formatter

 

SDHC is supported.
I do not think he has other functions, just play.

 

I need help when i put the R4 there is a message that said "An error has occured. Press and hold the Power Button to turn the system off. Please see the Nintendo DSi Operations Manual for help troubleshooting.". And in the micro y have this:
Games
TTMenu
iLL.iL
TTMenu.dat

 

And i have no games yet.

 

You will need to install Custom Firmware on your Nintendo DSi: https://dsi.cfw.guide/

 

I can´t get it, if you can put here the files i need to put in the sd card and how install that in the ninento i´ll appreciate that. Because I downloaded and do evrithing that said the web site but in the nintendo the sd appears empty.
