*this is not a modified or hex edited hboot. this is resetting your lock flag,so that your phone will correctly display locked on the hboot screen
ive verified the lock location on just about every s3 phone jpbear supports,as well as a couple s4 dual core devices- LTEvo,inc 4g LTE,and one S.
ive had a friend dump his DNA mmcblk0p3 and the lock flag location is the same,with an extra character that ive not seen prior. he cannot test the mods,as he is dependent on his phone for work,and cant be without it.
0x8400 on his dna looked like this:
03 00 00 00 48 54 43 55 01 00 00 00 00 00 00 00....HTCU........
now that we have s off,we an explore this further. first test would be to dump mmcblk0p3, hex edit it,changing 0x8400 to 00000000,and reflash it. id like someone fairly savy to do this,as i cant gaurantee it wont melt your shiny dna into a smoldering pile of goo
dump,edit and reflash in this manner:

if this is successful,some less experienced users are welcome to try flashing this zip files. see the following thread for zip file links and instructions: http://forum.xda-developers.com/show....php?t=2155955
again,this has not been tested on a quad core s4 phone. i cannot gaurantee the hex edit zips wil work,fail,or brick your phone.
i just wanted to get this info to the comunity so we can figure it out
