Changing USB Selection from PDA to MODEM - Android Software/Hacking General [Developers Only]

Hey guys,
I want to work out a way to change the USB selection when connecting a GS2 to a PC from PDA to MODEM.
I know i have come across the way to do it before but i can't for the life of me find it again!
I have Comneon Modem drivers to use once it comes up in new hardware as a modem but i cant work out how to change it.
I vaguely remember something about using an adb shell and changing a usb_sel to MODEM? But i cant seem to find the usb_sel anywhere ... only uart_switch, are they the same thing?
The device comes up in Device Manager as "SAMSUNG Mobile USB Modem".
Tried just changing the drivers to the ones i have but doesnt work for what i need.
Anyone know how to do this?
Thanks!

Can you share the Comneon Modem drivers please.
On SGS, with code *#7284# you can change the usb mode from pda to modem.

[Q] Anybody have luck using QPST with WP 7 phones?

As the title says, anybody have any luck using QPST with Windows Phones? I managed to get my Trophy into bootloader mode and recognized as "HTC USB Sync" but unfortunately wasn't able to configure it for connection via USB serial.
This QPST working for all Devce Qualcomm.
but not for all....
have you try to dial ##MFG# ? then enable diag mode..lucky you, Verizon MSL is 000000 .. I'm on Sprint, which is not using standard MSL
Yes, you must run phone in Diagnostic Mode etc.
I could get my focus into usb serial mode, but unfortunately Samsung Driver pack didn't even have the driver for it. Also the phone recognized as "PROTOTYPE something ... " in device manager.

You not must install new driver etc.
All Phone Quallcom, have a Factory Test Mode, then in this moede you connect yours device in QPST. This not a bootloader mode, this program reconnect device from FTM -> to BL etc..
You must have a. hex file, for your device.
for me this is a NPRG8650.hex - of course, is needed only when, you want reupload partition etc.

Can't connect GS3 in usb serial port --HELP--

Hi everybody, please someone could help me. I'm following the instructions
to recover my GS3 Imei, but in the driver install I stops because I can't connect the
phone like a serial port only gets connected like a usb modem.
I tried several drives with no results. Besides I canĀ“t obtain the secret
menu with *#7284#, only get two options
UART
- modem
-PDA
-LTE
USB
-modem
-PDA
To obtain the secret menu I've installed the Geek tool
Please help me to make my computer reconize like a usb serial port, I've tried several PCs with the same results
My system is Win7 ultimate x86
When you select (both modems) that should give you a serial port.
Is it a Verizon or Sprint GS 3?

Greetings
absurd problem not let me go
Hi, I have the same problem, I can't connect the phone like a serial port only gets connected like a usb modem.
AP: XXXXXX.I9300XXBLFB
CSC: I9300PHEBLG1
Company: Yoigo (SPAIN)
With stock firmware from SamMobile.
I think one solution could be to install Verizon or Sprint XXXXXX.I9300XXBLFB firmware, but this not exist, and if we install other Verizon or Sprint firmaware with different AP the phone can die.
I read all the topics on the forum about this problem and none reaches a correct concluision. I have installed the correct drivers for Samsung USB. Someone can help with this issue please?

I can't figure out eitheir its hard or soft.

i used different cables and pcs but still not recognised
yesterday i used odin with those options :
BL/AP/CP/CSC and checked
Auto-reboot
F.reset Time
phone EFS Clear
Phone bootloader update
it has taking some while to execute but after that my phone was working and detectable again by my pc the problem was resolved for a couple of hours, in the evening the problem occured again.
and i have tried the process again the same why but no connection at all.
i don't know if its a hardware problem or software related problem
because the usb work when i m in restore mode (Odin mode) otherwise no.
Its an advance problem i already check all about usb / cable and pcs related problem.
Problem resolved
I sent my S6 to Samsung SAV it take them 4 days.
they doesn't give me proper answers on what they have done but i saw that my mini-usb plug is new so i expect that they got this part changed accrodingly the samsung has no sign of damage its a clean operation.
Its now detectable. It was indeed a Hardware problem
i have the same issue but in a g928f
today i changer my lcd with the micro usb flex
so all is new except the main board and still is not recognised at any pc with any cable.
i am really starting to feel very sorry for this phone.
odin does not see it at all even at download mode.
i don't know what else to do.
Software or Hardware Issue
I have a s6 920t that I am suppose to pay for at the end of the day. I got it from a friend who bought it while overseas. The only time my computer detects it is in download mode/odin mode, I hear the sound and I see it as "Added". When I try to connect any other way I don't hear the sound my laptop makes when it has detected a new device also otg cables don't work. I just simply want to know if this a software or a hardware issue? Software I can fix but if it is hardware I don't want to waste my money. Please anyone reply as soon as you can so I can decide what to do.
Thank you
I have two S6 Edge and one of them started doing this (phone only appears on USB when in Download mode). When swapping the motherboard between the phones, it works. So the problem isn't with the motherboard, but the USB connection module attached with the ribbon cable... There must be a chip on the module which gets locked somehow and replacing the board is at least one way to fix it. Hopefully someone finds another method without replacing the charger board?

S6 920F no longer connects to pc

Idk if this is place to post
My issue is non of my pc detect my phone anymore. Tried stock cable, 3rd party cables but no different
Phone don't even show me different USB modes..
No change if on custom rom or stock
Hello my friend i have the same problem it detects in download mode but not in mtp or adb, did you find the solution?

If it is not an hw issue you can try dial *#0808# and try changing settings under AP

HELP! Can't connect to PC

Hi guys, i'm getting this problem and cant connect to pc and i think i've tried it all.
when i connect my phone to the PC, it stars charging but my pc doesn't recognize the device, and my phone doesn't show the notification to make it file transfer.
Could it be a computer issue?
it seems not, i've uninstalled and installed drivers (ADB and Fastboot, oneplus drivers, google drivers) and the problem persist, and even try it on another computer and its the same, the phone does not appear even on Device Manager.
Could it be the Cable?
I don't think so, i'm using the original oneplus cable, it use to work really well before, and i have even connect other phone with the same cable and the other phone is recognize by the computer, so it''s not a cable issue... but I still when to a Tech-store and try other USB-C cables with their computer but my issue still persist (phone isn't recognize, just charge).
Could it be a phone software issue?
Maybe? but i discover this issue 3 weeks ago and a i was on EVOX rom and i thought it would be solved flashing another rom, and i CLEAN FLASH Resurrection Remix Rom, but then the problem was still there!
cant connect even on FASTBOOT MODE...
BTW, before installing RR, i Installed OOS 10.3.4, and still my computer doesnt recognize the phone, YES i have enabled developer options and USB debugging is enabled, and USB PREFERENCES to File transfer, but its not helping me, the "usb for" option its all grayed out and cant change that.
Right now i'm stuck on a RR build without Gapps, and i lost ROOT and RECOVERY, and as you may think, i cant install any of them because i cant connect to my pc, so i'm in a pretty difficult situation here hehe, could you please help me out?
This helped me. Hope it works for you too

Thanks for your reply, but this didn't work because my device isn't shown on device & printers, or anywhere as far as i checked...
PROBLEM SOLVED.
I think this is the silliest solution I've ever seen, it was just DUST, i clean my USB-C PORT (with a mask xD) and then pluggin, AND VOILA, it worked!!! so keep your ports clean everyone
