[Windows 10 Mobile] nate0:
As we currently know it the open market FFU for the IDOL 4s will not flash properly to the open market model IDOL 4s phone. The below steps and attached files will allow this to change.

I was thankfully able to find this information due to a member over at 4pda who put together steps using the full engineering tool (link). They shared the link here to that post. Since I cannot attach the full files of that tool here due to size restrictions, I came up with an alternate method to share on this site and attach the needed files to flash.

This is a an alternate method to flash your open market IDOL 4s with the Open market FFU. You do this at your own risk. I personally feel it is relatively safe to use this method since we are in EDL (Emergency Download) mode anyway, yet even though I have done this now 4 or 5 times flashing an ffu to the IDOL 4s there is still a risk that something could go wrong. So I/we are not responsible if you kill your phone. The following directions assume you are running Windows 10 Creators update on the PC you are flashing from. If you need assistance downloading or installing the Qualcomm HS-USB QDLoader 9008 drivers you will need to look on the internet or search XDA forums. There are plenty of resources on that. The good thing is that when I tested it from my tablet for the first time the device showed up in device manager as QHUSB_BULK. I simply right clicked it in device manager and updated the driver to get the correct USB driver installed. It flashed fine after that. With that out of the way I can share the information to flash the open market ffu.

Make sure you charge your phone prior. To be safe 100%. This can be done at the minimum 40% charge or maybe 20% but that could be pushing it depending on the health of your battery.

--Obtain the open market ffu file

Download the open market firmware ffu from WDRT by opening the tool and selecting the open market IDOL 4s and advancing the steps/windows until it finishes downloading. Click cancel once done and close WDRT. By default it should download to C:\ProgramData\Alcatel\Packages\Products\6071W\RTM_IDOL_4S_Open_F1052.16.09031.50700_1052.16.09031.50700.FFU

--Download the attached Idol4S.zip

Download the attached zip file

In the attached zip file you will find the following:

Idol4S_PRO_WIN_NPRG7627.bin

rawprogram_6071w_OM.xml

emmcdl.exe

You only need to use the emmcdl.exe file and the bin file. Don't worry about the xml file for now.

--Setup the files for flashing

Extract them to their own folder. So for the sake of argument we have them here: C:\Idol4S\

There will be 3 files in the Idol4s folder. Next move the FFU file you downloaded previously to this folder for simplicity.

Now you will see 4 files there under C:\Idol4S\:

RTM_IDOL_4S_Open_F1052.16.09031.50700_1052.16.09031.50700.FFU

Idol4S_PRO_WIN_NPRG7627.bin

rawprogram_6071w_OM.xml

emmcdl.exe

--Reboot your IDOL 4s into Emergency download mode.

Turn off your Idol 4s windows phone. Once powered down push and hold the volume Down Key in and keep it held in.

Next plug in the phone to the USB C cable connected to your PC.

It will vibrate but continue to hold the Down volume key for a second or two. You should see device manager recognize the phone as something like QHUSB_BULK or Qualcomm HS-USB QDLoader 9008.

If it shows up as QHUSB_BULK or something else you need to install the correct drivers in order for it to appear as QDloader 9008.

Once it shows as QDloader 9008 like the pic below. Write down the port number it shows up under...in my case COM3

--Flash the phone

Once in EDL mode open the folder where your 4 files for flashing are stored. Then either open a powershell prompt or command prompt Click File > Open Windows PowerShell or click File > Open Command prompt.

Begin to run the below commands:

from Windows PS --

.\emmcdl.exe -p com3 -f C:\Idol4S\Idol4S_PRO_WIN_NPRG7627.bin -ffu C:\Idol4S\RTM_IDOL_4S_Open_F1052.16.09031.50700_1052.16.09031.50700.FFU

from cmd --

emmcdl.exe -p com3 -f C:\Idol4S\Idol4S_PRO_WIN_NPRG7627.bin -ffu C:\Idol4S\RTM_IDOL_4S_Open_F1052.16.09031.50700_1052.16.09031.50700.FFU

The flashing takes a bit of time. You will see lots of output scrolling. Just leave the device and the screen alone for a bit until it finishes. Once it's finished the phone will reboot automatically.

If it stalls at he beginning or fails. Reboot your phone and put it into EDL mode again. Or reattach the usb cable and put into EDL mode again. Retry the command.

Again, to repeat, if you choose to do any of this it is at the risk to your own device. Thanks.
