i had tested this quite awhile back, and i can confirm that there is indeed a client block on it along with the server side things. hexing the client is required
search: 03 C8 5f 89 4b 08 5e 5b
replace: 03 C8 5f 90 90 90 5e 5b
the code is buggy, you may notice why if you try it. also when searching you will find more than 1 result, just try them all until you get it. this was tested with an older client, not sure about renewal.
note: this works assumings that you have already removed all the checks server side.
