Hello all, newbie here!

I have read through guides on how to access my K750i's internal file system using FAR manager, and have got stuck at a certain point, where the phone is not doing what it should do!

Firstly, I have been using this page as a reference:
Using Far Manager to hack Sony Ericsson K750i CID49 mobile phones

On the section "Using SEFP to access your phone" I have got as far as point 4. My FAR manager screen looks the same as here:


HOWEVER, the instruction states "You have two choices: FLASH, to flash main firmware and apply patches; and FS, to have access to phone's internal filesystem. Select one of them, according to what you want to do."
SO I select FS (as I wish to disable the camera sound). I selected FS and hit ENTER, and instead of doing the correct action and showing me the filesystem, instead my phone Switched itself on and a new screen on FAR manager reads:
"EPIUSB: speed changed from 921600 to 921600
***All loaders are taken from SETOOL2***
Sending break_in ldr: cid49run: sent 1 byte(s)

command progress: 1 of 1 byte(s)"

Nothing else happens beyond this point, and to exit the FAR manager I get the "windows cannot end this program. it may need more time to complete an operation" - of which the END NOW button is pressed!

I had left FAR manager for 2 hours, so I think it is breaking every time it gets to this stage...

So, How can this be fixed so I can get rid of the camera shutter noise???!!

(thanks in advance for any help)
