hyundaifirmwaredecrypter's Issues

Tucson 2021

hello, it should work for any model? i tend to try it on a Tucosn nx4 with 8" display.

How about October 2023 version?

Great work! Thank you very much, I read your deciphering of the Hyundai code.
I tried to do the same with the October 2023, but the update file is now called
upgrade.lgk and it doesn't seem to be a zip file anymore.
Mine is CAVNEU_H, 2017 ioniq btw.

I need to get into the engineering mode actually to set the location of the car (the GPS is not working due to my Factory Reset blunder). However, they seem to have changed the code from 7,5,3 to something else, because although I can get into the dealer mode with the 7,3,1 volume, the 7,5,3 does not work.
Any ideas? Many thanks!
