After version 1.2.46 and 1.2.47 upgrade, hack line for hero sometime comes huddle. So, you should check 12 lines below blue line first, this line say the level of hero you are going to hack. If this line has right value then you'll apply the hack. If not, check for some hack code above and below, i think 2 lines above first hack code is the best choice (try this value first).
Eg: This example is solution for AFG0KILLA case.
1. You have a 6 star Thunder God and you find 56 is hack code for him. Go to "Edit bound memory", check the value of 12 lines below blue line. If that value is 120:120:120:0 => right value => apply hack.
2. If that line says 80:80:80:0 => this hack code is for 4 star Thunder God => turn back to hack code and go to value 58 => check again, and apply hack (it must be work). It easily find out value 57 is hack code for Thunder God 5 star, 55 is hack code for Thunder God 3 star, and so on.
3. If that line says 160:160:160:0 => this hack code is for 8 star Thunder God => turn back ... and go to value 54.
4. If 2. and 3. is not your sittuation, you must find out each value above and below value 56 till you find the correct value for your 6 star Thunder God (120:120:120:0 in 16 lines below blue line). Fortunately, you just find 2-3 values above and 2-3 values below 56
P/S: I confirm hack trick for gold and mana for upgrade does not work for all case.
