As i said before i have posted a video showing how to do inbox crate hack.
There are 4 steps you have to follow:
1:Find your coin pack value and copy it.
2:Search --> XD;1.29:: ,At your search you gonna see multiple results, search and refine 1.29
3:Goto 1.29 go to the pointers accordingly and copy the adress.
4:Search 900;550(thats your boost values),goto 900 and then at the 4th pointer edit and paste the adress you copied from 1.29.
*X is your coin pack value
*With 1.29 there are 3 or 4 different packs,you have to try wich one you want.
