Flash LED not installed? (I think )

Hello all,
I have flashed a no-name tablet and all working fine except for LED flash.
Ran Z-Devices app and it shows that the LED is no present. I am assuming that it is not installing.
Tried a torch app but no light found. (Uninstalled quickly.)

I have hard reset a couple of times with the same outcome. I want eliminate an install at boot issue before ripping the thing to bits, to check connections.

I've had a poke around and hope this helps

\system\etc\camera.cfg
Line 69: used_flash_mode = 0
Line 70: key_support_flash_mode = on,torch,off
Line 71: key_default_flash_mode = on
Line 145: used_flash_mode = 0
Line 146: key_support_flash_mode = on,torch,off
Line 147: key_default_flash_mode = on

Sysconfig.lhs:
vip_dev0_flash_en = port: power1<1><0>
vip_dev0_flash_mode =
vip_dev0_af_pwdn =
and
vip_dev1_flash_en =
vip_dev1_flash_mode =

I'm a newb but am quite happy to manually edit any files that need to be modified.
Could someone give me some suggestion as to where to look to solve this? Or what other file information you require?
