[Samsung Focus S] dazza9075:
Hi guys,

This is all about developing the Focus S, since we are on our own on this one I thought id start the ball moving but it would be great if others can help, my first target is to try and download as much of the device as possible

Can I promise anything at all? nope

Have I achieved anything yet? well id say 1 step above doing nothing at all, if you can call that progress then yes, there is progress

Is it even possible to do anything? i dunno

Could i brick my device? possibly, i honestly don't know

in short, this is me blindly wondering in the dark with absolutely no direction what so ever!

So what have i done, well, i managed to get the Focus S talking to Qualcomms diagnostic utility, QPST and RevSkills CDMA Workshop

I cant get QXDM to install on Win 8 x64 and im not sure we need that one anyway

it is possible to edit stuff on the phone at a very low level, NOT OS level, it should be possible to download the various images on the phone, but ive yet to have any luck with that, it keeps coming up with "Arm9 fatal error"

ive been able to download and backup various phone settings but this is still outside of the OS#

I can play about with the EFS but there are several folders that i cant get in to yet

So far,both the samsung download mode and the ARM9 (?) download mode IS visible and installes as a com port, but there is no response on that port, i can only get a response within windows when i enable USB diag mode....

i decided not to link to the various tools ive mentioned here, i dont know the legalities of it all so use google, they are all easy to find.

Handy Diagnostic codes

*#7284# - USB Path control (select to change how your phone communicates with your computer)

*#197328640# - The Root Menu (seriously, don't get too cocky, you could bugger up your device)

Samsung USB Download mode

Turn off Device

hold the camera button and the Volume UP

Whilst holding those two push and hold the power button until it vibrates

Samsung Device Hard reset

Turn off Device

hold the camera button and the Volume Down

Whilst holding those two push and hold the power button until it vibrates

Follow on screen instructions

Enable Diagnostic mode and Connect to QPST or other GSM/CDMA software

Download and install the Samsung drivers above

open the diagnostic app and dial code *#7284#

Select Modem,USB Diag

Reboot

When you plug the phone in you should see a COM port install and appear in device manager

load QPST configuration

Click on the Ports Tab then Click add new port

Select your Phone com port

Click OK then select the phone from the list, hit enable

Click on start clients then you can play with a bunch of options

Please note that this is a serious piece of kit, its designed for low level editing, what I mean by that is that it couldn't care less about if it works or not after you finish playing, a couple of other software options to play with are CDMA tools and RevTools both have the potential to paperweight your phone!

NOTE: Zune will not connect and whilst connected to PC you may lose all GSM connectivity whilst connected as well.

Enable FTM (Factory Test Mode)

open Diagnostic app and dial code*#197328640#

select 6 (common)

Hit Back until you back to the main menu then win key to Windows

REBOOT to enable

NOTE: You will lose ability to connect to GSM with this enabled, a reboot is required to enable it after its set and to deactivate it, ive not found a noticeable difference with this on
