on your HTC HD2 with Kikat where is the app data stored internal or external SD card? if all your data is stored in the external SD then speedcams won't work on kikat version as it does not allows write access to external SD introduced by kikat firmware. You need to have some information on the internal SD and some information on the external SD.

On the internal SD create following folder structure on the internal sd

iGO
---content
--debug
--font
--gfx
--license
--save
--ui_android
--ux
data.zip
sys.txt

In the content folder only have the following folders
global_cfg
dictionaries
lang
speedcams ---> put the speedcams information here
tmc
userdata

all the rest on external SD

rename the iGO folder on your SD to Addons and only have the content folder within this.

in your sys.txt file add the following

[folders]
has_secondary_root=1
android_secondary_root_path="/Removable/MicroSD/Addons"

data="/storage/emulated/0/iGO"

you must have the correct path to your addons folder as shown in bold above
