Need help with R4i 3DS

Hi everyone! I am new to this forum so please bear with me.I have a 3DS I am trying to get to work again with my R4i card.
Currently, the 3DS works fine but when you select the game to load the R4 I get an error message."An error occurred. Press and hold POWER Button to turn the system off. Please refer to the Operations Manual for details"I am guessing this occurred because of an update?
My current version is 4.5.0-10UI was using R4i 3DS card. The kernel was downloaded from r4i-sdhc.com
I have tried to put the new updated kernel on the card: Version 1.65b
However, I just get the same error message.How do I proceed. I think I have read somewhere that I need to update the firmware on the card... but I do not know how to do this. Do I need to do this with another DS? Or do I need to get a new card? Looking for any suggestions...Can anybody help?

Your 3DS's latest firmware blocks use of any flash cartridges that hasn't support v.4.5.0-10 firmware.
Check your R4's official website for an update/upgrade so that it can be use on the 3DS's v.4.5.0-10 firmware.
You can't perform the updating/upgrading on your own 3DS console, since it blocks itself from reading that cart.
You need to borrow/use a DS console (NDS/NDSL/DSi/3DS) that hasn't been updated to that v.4.5.0-10 firmware.
And just read the method from your R4's online manual regarding upgrading/updating their brand's flash cartridge.
If there isn't any update/upgrading package from your cart's website, either wait until one comes around (God knows when) or buy a new cart that had been pre-installed with the latest version that will immediately run on v.4.5.0-10. Next time, don't upgrade your console before upgrading your cart. This is what happens when you are careless.
