Still no breakthrough? Sorry lad. Hmm.... It would appear to be a very recent r4, given the date on the label, yet that site mentioned (r4isdhc.hk) has been closed for quite some time: evidently an old flashcart with the addition of "2024", apparently to rejuvenate it in the eyes of foolish and reckless buyers.
Sorry, something obvious and repeated several times: before buying a flashcart, can't you search online if its kernel is readily available? Or read some reviews or opinions online from those who have already purchased it? With a quick search you will easily find that this r4 is being criticized and devalued by multiple users, and it is a titanic feat to find the corresponding kernel online.
By now the die is cast...
