Or does that terminal command bypass this fault? Have you guys then managed to restore your phone since your able to now go into qualcom usb settings?

Yes if the 'Qualcomm USB Settings' button disappears then use the terminal command to access it instead.

In the modem.bin file i have came across these lines at line :149480>149481>149482

S000=%03d S002=%03d S003=%03d S004=%03d S005=%03d

S006=%03d S007=%03d S008=%03d S010=%03d S030=%03d

S103=%03d S104=%03d

now if we take a look at this we can see it looks to relate to imei descriptions somehow.

Highlighted in bold are 5 x 3 char encoding which equates to 15 being a IMEI number is 15 we can see a relation.
Now having access to the ability to open modem.bin without corruption/encryption would enable us to have a better understanding on how to restore out IMEI numbers. (high expectations here)

now im not sure of the significance of this or how to manipulate it. but i will enter some codes into it and see how we go.



I have also come across a plugin named buildagent when gogling of this it gives me a Plugin for microsoft software. maybe someone can make use of this to decompile?

Ok so why are people still having this problem if they can access the qualcom usb settings? Is it because they did not have a backup of the qn before it was lost? So please be clear about this.. people that have previuosly made backups of efs and nv data should be safe even if they loose the qualcom usb button because they can access it through terminal and restore it that way. Please confirm

we'll im on Official Telstra 4.1.1 RUU with stock kernel and recovery and i dont have any *#id# commands that work.
i type one in and it just sits there and nothing happens.

I have a little grey box that pops up and tels me im in Factory Mode-ON

i cant access the phone with ADB devices or EFS explorer

i got no power button menu its just restarts when hit.

so for me i cant do Squat unless it can be done from the android terminal emulator.



Im also wondering if we can direct inject imei via qemud with something like

Code:
qemud=`getprop ro.kernel.android.qemud`
case "$qemud" in
    "")
    radio_ril=`getprop ro.kernel.android.ril`
    case "$radio_ril" in
        "")
           #not sure of ro.ril.imei or just ril.imei
          #or do we need yes? or 0 / 1 on off etc?
        setprop ro.ril.imei=123456789012345 yes
        stop ril-daemon
        ;;
    esac
    ;;
esac

**** this is starting to scare me... Narcassiss if you previously backed up your efs and NV data, is there something you would be able to do now or still nothing?

Cool
regarding the backup. I did a efs backup by the aroma installer from SSH v1.0 many days ago but as I found out it was pointless anyway. and I candidate seem to workout how to copy the efs.img back to the phone I did dd for=/efs.img of=/dev/block/mmcblk10/ but I was not able to get that command to work from the terminal as I got no adb from pc as phone is somehow stuck in factory on mode

as for the nv backup don't have one. don't have the nv files on both my s3's.

although I do have a 700$ development phone now and one working. lucky I got two.

well now to workout how to get my pit file from this phone and inject It over to my other one. as my phone won't boot past the logo cause I accidentally had partition ticked on the bloody Odin. I got to pay more attention but damn me Grimm was on. fml

so yes still nothing. all my java files can get a good run but don't suceed in getting my imei back any of the random ways I tried. or even read the unknown name for that matter and to think I could Of been fishing today instead of coding to no avail.
