Hi there,
I have been attempting to use QPST's memory debug program to dump the phone's memory. Specifically I'm trying to get the ebi_cs1.bin and ebi_cs1.bin files.
My problem is that QPST will detect the phone fine when USB Settings are at RNDIS + DM +Modem or DM + Modem + ADB modes but once I try to run the memory debug app, it requests to put the phone in download mode and QPST will no longer detect the phone when it is in download mode. When the phone is in download mode, it also does not come up with a Comport in device manager (hence QPST can't detect it), but ODIN will actually detect it. I must note that when the phone is on and not in download mode though, QPST and ODIN detect it on different comports.
I have uninstalled and reinstalled Samsung USB drivers numerous times as well as trying different versions of QPST, two different usb cords, and three different usb ports.
If anyone has any idea on how to dump these files with QPST or via alternative methods, please help me!

Any ideas or alternative methods?

Hi, please help me with this. I need to activate the Diagnostics COM port in the SGH-i637.
Some info about this phone:
- This phone has a 32 bit Qualcomm MSM7201A CPU and Windows Mobile 6.1 OS.
- When connecting this phone as Modem, only modem driver is installed in Windows.
- During Flashing procedure (Turn off phone, press J, connect USB cable to PC, do not turn on phone) a Qualcomm device is detected and installs a COM port.
- Entering *#197328640#, then Option 9 (Common), then Option 4 (Diag_HFK_Configuration) only UART3 and UART 2DM are available (no USB Diag)
- Entering *#7284# nothing happens. Running Emchanger.exe or dataconnection.exe, you can choose between PDA or USB mode, but nothing happens.
- This phone is very similar to Samsung GT-B7320 and GT-B7330, on those both phones, changing from PDA to USB works (entering *#7284#) and installs the Diag COM Port.
So, any clue if there is a way to activate the Diagnostics port on this i637 smartphone?
Thanks!
Samsung GT-B7330 QXDM
I'm also working with QXDM and Samsung phones. I'm trying to used the USB modem mode(*#7284#) on my GT-B7330 but I can't find the right windows driver for it. Could someone provide me with the Samsung USB modem for the GT-B7330
I've search on the web and although I found many versions I could not get one which worked with the GT-B7330
Thanks
Running Emchanger not happening
as i wrongly updated my gt-b7320 to AT&T sgh i637 windows 6.5 now some of the keys are not working and led is always on
when i connect the phone to pc no COM port is showing it doesnt enter in boot mode as when i do it manually by *#7284# it shows cant find emchanger.exe
so is it possible to get my orginial version back by flashing it with original file.....
can anybody help me.......
Thnks in Advance
I'm a programmer but have no experience in Windows Mobile/CE programming before.

Well I started having this wierd problem.
When i connect my nexus 4, in mtp mode, i dont get the yellow device logo at the device manager window.
All i get is adb installed.
as a result i cant transfer files from my pc...
Although i could install a custom rom via a toolkit, i cannot transfer files...
any help would be appreciated
thanx
You are in USB Debugging mode, which require a different driver than with it disable. You can try uninstalling the driver (check the box to also delete the driver file), then reinstall it using Universal Naked Driver (link below), or Google USB driver.
If that don't work, try disabling USB debugging.
I'm trying to install Samsung mobile phone drivers but no matter what I do I miss these drivers when I connect my Samsung Galaxy Y:
CDC Abstract Control Model (ACM)
CDC ACM Data
CDC OBEX Data
CDC Object Exchange (OBEX)
I have googled for solution and I have followed recommended actions (install Kies, install latest drivers, reinstall all, use "have disk" method) on different operating systems (Windows XP, Windows 7) but I got no success.
My phone doesn't boot (I need to flash it with Odin) so I have tried it all in recovery or download mode but I understand it should not really matter as it's Windows issue, not a phone. I'm using original Samsung USB cable.
Could somebody with a working setup could check if they have above devices correctly installed and provide me more information on the driver file? I mean the information from driver details tab in Windows, ie. name of *.SYS file, *.INF file so I could at least check if I have a driver on a disk.
Any other suggestions also welcomed!
Kies is useless & is not required for galaxy y gt-s5360 as it's not supported for firmware flashing on this device so uninstall it
Uninstall any Samsung drivers you have installed from add/remove programmes
Goto my firmware thread at top of Dev section or link in signature
Download & install USB drivers on my thread
Download the firmware from my thread depending on region
Follow the instructions fully
You can manually install drivers if you wish by clicking on unknown device/device with yellow! click have disk & navigate to where you installed Samsung drivers eg c:/programme files/Samsung
It has finally worked (Windows XP)! I have just installed drivers and followed your instructions (with download mode, not recovery mode). Initially I had other unrecognized devices (very generic usb ones) but after a few attempts (usb plug out, usb plug in) the phone has been detected successfully and I managed to flash it. Many thanks!
Sorry, I forgot to mention. I had also removed a battery.
I have the same issue, Could you please paste the links for downloading the drivers.
Hi all,
I have been having some trouble following a guide on how to add GSM+LTE bands to this device. Specifically, I am struggling to connect to this device in Diagnostic Mode.
I am running Windows 7 x64. I have installed Samsung USB Driver v1.5.45.00. I have tried an updated driver but I seem to have had less issues with this version. I have also tried using Qualcomm USB Drivers For Windows (QD Loader) but when I select this folder to search for an alternative driver instead of the one Windows assignes I have to manually select an *.inf file and the options (HD-USB QDLoader 9XXX) does not make any sense to me which driver is required for my device.
I can run ##DIAG# in the Phone app and bring up PhoneUtil which brings up a menu to select CDMA MODEM / PDA and I have used both with no success. This menu allows me to access RNDIS+DM+MODEM. If I try to use other applications to switch to CP from AP in other USB settings or PDA to MODEM the phone disappears in device manager.
In QPST Configuration I have to untick "Show Serial and USB/QC Diagnostic ports only" to show the port and select the device. If I continue and use Software Download to back up the xQCN (NV memory) file it gets stuck at 12% and gives me an error "Could not Communicate in Diagnostic Mode"
If I use CDMA Workshop to do a backup the files hex just shows 00's and EFS Professionals backup is the same.
I have tried using stock Lollipop 5.0 firmware an enabling CP logging, rooted 5.0, a custom ROM including CM and I am currently running rooted 6.0.1 firmware.
I used Idoneapps paid service to find the SPC for my device but I don't believe there is any equivalent service to enable or disable the bands on my device.
All I can consider is wrong is the possibility of not having the right drivers but I have no idea where to find the right ones. I am at a bit of a dead end, any help would be appreciated.
Thanks.

man, if anyone can shed some light on this, itll breathe some new life into my phone. I looked for the very same thing a while back as i switched to H2O wireless using AT&T towers and its working, but just on HSPA+ and thats because all of the LTE bands arent unlocked on my phone. QXDM and QPST are the tools we need, but the driver issues are whats stopping me too. Anyone with insight would be greatly appreciated

Problem:
Have a V35 that just can't seem to be accessed properly by QFIL.
When I try to open partition manager, it stops for a bit and then gives me an error (function: sahara_rx_data:277 Unable to read packet header. Only read 0 bytes)
What I've tried so far:
(from this guide: https://forum.xda-developers.com/lg-v35/development/bootloader-unlock-root-instruction-t4052145)
(also used the V40 thread as reference: https://forum.xda-developers.com/lg-v40/development/unlock-lg-v40-via-9008-root-t-mobile-t4042207)
On PC:
Installed LG Drivers
Installed 9008 Drivers
Installed QPST w/ QFIL (latest version from the QPST website 2.7.480)
On V35 Device: Enabled OEM unlocking and USB debugging
In QFIL: Set file system to UFS, selected the prog_ufs_firehose_Sdm845.elf file for flat build programmer.
I can get the V35 to blank out and device manager shows the QUALCOMM device under ports list.
QFIL can detect the device in the COM port. (I can move the usb cable around and the QFIL program will follow the change of port around)
I've tried updating the drivers on the 9008 driver device on first time use as suggested in the V40 thread.
I've tried uninstalling and reinstalling the 9008 drivers and QPST as suggested in the V40 thread.
I've tried moving to different USB 2.0 ports as suggested in the V40 thread.
I've tried swapping cables twice, including using the original USB A to USB C cable the V35 came with.
One thing I haven't been able to do is assign the search path on "Select Flat Build" bar. I couldn't find any files to download and place in the search path so I assumed it was unnecessary for getting QFIL to work.
Any ideas?
Wild guess, other USB driver interfering?
What CPU and chipset are in your PC?

Ended up moving to a different PC and doing the following:
1. Install an older version of QPST 2.7.474
2. Update drivers on device manager to change the name of the detected device from the old name to Qualcomm.... 9008
3. Change file system to ufs from emmc.
Could start reading the contents of the device after that. I didn't install LG drivers until I had to connect to adb to call "fastboot oem unlock".
