.plt:000099E0                                         ; sub_25C44+Cp ...
.plt:000099E0                 ADRL            R12, 0x509E8
.plt:000099E8                 LDR             PC, [R12,#(ptrace_ptr_0 - 0x509E8)]! ; __imp_ptrace
.plt:000099E8 ; End of function ptrace

Look around for MOVS R1, #0x1F or something like that and NOP it (C046)
