I've seen multiple posts in the threads regarding the unlocked SM-G955U1 firmware on how to get the phone back to the original carrier firmware in the event somebody wanted to return the phone, or whatever.
So there are a couple of different ways, you can use Odin and download the appropriate firmware for your model/carrier via a site like Sammobile, etc... or what may be the best option (if you don't have a premium subscription to some of the firmware sites) is just use the SmartSwitch app from Samsung.
My device is a Verizon SM-G955U that I was able to successfully flash to the SM-G955U1 G955U1UEU1AQDC firmware.
If you open up SmartSwitch it actually identifies my G955U as a G955U1 due to the firmware, so you'll need to make sure you don't have your phone connected to your computer while you're doing this, otherwise SmartSwitch will simply download and re-install the latest G955U1 firmware version available, not your carrier specific version.
1) Click "More" from the main screen of SmartSwitch
2) Click "Emergency Software Recovery and Initialization"
3) Click "Device Initialization"
4) If you do not have your device attached to your computer via USB, you'll be given a field to enter your model number, if you do have your device attached to your computer, exit, unplug your device from your computer, and try again.
5) Type your model number in (e.g. SM-G955U) and click "Search".
6) You'll be prompted for the serial number of your device, you can get this from the Status screen of your phone.
a) Your serial number will be checked against a Samsung database to make sure it is both valid, and it matches the device model number that you entered.
b) If you get an error, make sure that you have entered the correct model number of your phone, Samsung is using a serial number database so that people cannot use this application to install other versions of the
S8 firmware on models which they were not meant to be on (e.g. I can't type SM-G955U1 as my model and then use my serial number without getting an error on this screen, since my serial number is linked to a
SM-G955U model.
7) Follow instructions, you'll need to re-connect your phone, and boot it to the bootloader screen by powering it down, holding the bixby + volume down + power buttons.
im sorry man smart switxh dosent have this anymore

It sounds like there was either an issue when flashing or a problem with the firmware you have used.
I would advise using Smart Switch on your computer to force another update instead of using ODIN.
Type *#06# and make a note of your serial number then turn off the device.
Open Smart Switch on your PC (Download Here if you don't have it) then in smart switch press MORE then select 'Emergency Software Recivery and Initialization'
Put the phone into Download Mode and connect to PC and wait for drivers to install (you may get a message saying it is incompatible, ignore it).
Click on the Device Initialization tab.
Enter your device model 'SM-G935F' and press OK. Then type in your devices Serial then press OK.
Now follow all steps until device is flashed. This could fix the issue.
Hi Guys,
i need the original Software of the Samsung J7 Duos of 2017.
The Phone has the Number SM-J730FZKDDBT
Could somebody give me the correct Software?
Had a big Problem with the phone and accidentlly deleted the original Software. :crying:
Now the Phone is running with the J7 Pro Software an i have Blur and sometimes Stripes on the Phone.
I found one here: https://mega.nz/1dd9e683-af73-4d23-8f0c-1adab29698d9
Note that this is the firmware for the SM-J730F as they come in Switserland.
Another (better) option imho is to download Smart Switch from the Samsung website. (link: https://www.samsung.com/us/support/owners/app/smart-switch)
Once installed, it's not that difficult to get your original firmware back.
1) Make a backup of your phone (as it will be erased completely)
2) Switch off your phone and boot it into "Odin mode" (hold volume down + power + home until the device boots, release the power button but keep holding the other buttons. Once you have the confirmation screen, confirm using volume up)
3) In Smart Switch (once installed) click on "more" followed by "Emergency software recovery and initialization".
4) When the following screen is loaded, click on the "Device intialization" tab.
5) Enter your Model name at the bottom (in capital letters) and click on "search".
6) When your model number is recognized, you will be prompted to enter your serial number.
7) Once entered, click "ok" to start searching for the firmware for your original region.
8) Follow the next steps as explained on-screen (don't have my tablet - Samsung Galaxy Tab S - with me now so cannot give you any more detailed instructions).
Note that I cannot find my phone when entering the model and serial number (SM-J730F/DS. Model not found, and combination with SM-J730F and my serial number gives no results)

You can go to download mode to check your exact hardware model. The things in download mode can't be changed and are telling you the truth.
To go to download mode, power off your device completely and then press volume up + bixby + power button. it will ask you if you really want to continue, press yes and then look what it say by "Model Name". If you're at it already, also check the "warranty void" if its 0 or 1 (0x0 or 0x1).
To exit Donwload mode just press volume down + power button for 7 seconds.
You then can download the newest software for which ever device you have.
@jaannnis
Thank you! So in download mode, i found no phone model, instead i found carrier:xaa also the waranty void is 0x0 (no rooted). I google a little bit and found that is the USA unlocked. Also i just realised the back of my phone written model SM-G950U1. I think my hardware is USA unlocked but the firmware is hongkong (is hongkong better than usa unlocked??)
So what do you think i should? the safest way please. i have no waranty, i bought it online shop and the shop is closed.
should i flash usa unlocked firmware with odin? https://www.sammobile.com/firmwares/galaxy-s8/SM-G950U1/XAA/download/G950U1UEU2CRB9/214007/
or hongkong? or with smart switch?
Edit update:
1. so i tried smart switch 4.1.17054_16 with device initialization, with various combination (correct uncorrect model, correct uncorrect S/N).
- With wrong sn and anything samsung model the pop up is "unable to find the serial number, model name, or IMEI on the server. Please check and try again"
- correct sn and anything samsung model except SM-G950U1, the pop up is "please check the model name and S/N, and enter them again"
- correct sn and SM-G950U1 the pop up is, " 'SM-G950U1' does not support initializing. Please contact our service center."
2. Odin 3.12.3 with SM-G950U1, 2017 december nougat. The installation failed.
hope it helps to overcome my problems. thx
Hi guys, I've been looking on the forums and i didn't find a way to solve my problem, my Samsung J5 J500m has the "An error has occurred while updating the device software. Use the emergency recovery function in the smart switch PC software" screen. I've tried both smart switch and Samsung kies and it hasn't worked, the thing is that i don't have the "depuration usb" on, nor the eom unblocked, the phone interal memory is almost full and i don´t have any custom recovery such as twrp or others.
If anyone knows how to solve this or can send me to the right thread i would really appreciate it

You don't need usb debugging or oem unlocked to recover your phone. Smart switch's emergency recover detector isn't that reliable sometimes it doesn't detect devices in emergency recover mode. However there should be a second tab in smart switch to recover your phone. It's "device initialization", device initialization works similar like odin. If you don't have this tab then you probably installed a newer version of smart switch. If that's the case follow this instruction:
1. Uninstall current installed smart switch from your pc
2. Download this ealier version of smart switch from samsungs official download center.
3. Install it. Once you run smart switch you might get a pop up screen to update to the latest smart switch version: don't update it!!. press cancel.
4. Now reinstall usb drivers in smart switch: more > reinstall device driver. Make sure to disconnect your cable first.
5. if finished, locate to More > Emergency software recovery and initialization > device initialization
6. There is a section to enter your model name, enter SM-J500M. Press search.
7. Now you need to enter your serial number. As you can't access your phone to view your serial number, you can still find it printed on your phone packaging or behind your device's battery. Enter your serial number in S/N section. Press confirm. Note: New devices don't support "device initialization" but your device should be still supported
8. Now you should see a pop up window where you see something like "initialized version". Press Ok and let smart switch recover your device. You should see a bar appearing on your device screen. If you press "ok" be warned! this step will wipe all your data on your internal storage!
9. After it's finished your device should boot normal again.
Good Luck! :fingers-crossed:
It says "this devices don't support device initialization"
Thanks anyway,

Can you access odin mode (volume down + home button + power button to boot to odin mode)?
If yes, flash a stock firmware for your device using odin. You can download stock firmwares from SamMobile, SamFrew or Updato. Make sure you run Odin as administrator
Thank you, it worked!! :victory::victory:
i was trying whit a sammobile firmeware, i supose it was the wrong one, thanks for sending me the right one
Hi you all for those trying to unlock and root the Samsung Galaxy S8 SM-G950U snapdragon locked for USA sprint company. Voila! it is possible even if you got the 6th version firmware (latest update to October 28, 2019)
After some days trying to root and lock unsuccessfully and looking info I gave a shot to movical wesite. Price is very cheap and they guide you into the process. Basically the steps are:
1- download and run unlock client software and select your model. (They send you all the links)
2- Select you phone model and Insert the license provided by movical website in the search bar.
3- Install samsung drivers into the pc and connect the phone via usb to pc
4- Open the device manager (window+x ) and see what type of connection is showing the phone. If it say "modem" it will no work. You must set up to "ADB" for that follow this step (two options):
First developer option must be activated
4.1 Dial *#0808# if this not work (in my case didn't) then
4.2 Dial ##3434# when prompted select CMDA, another screen will show up, then tap on DM+MODEM+ADB.
4.3 Check again device manager after plug the phone again into pc it should now say "ADB"
5- Run Unlock client set up the settings and it will return a message that is not possible unlock cause flash must be done first and the software provide the link to download the files needed for make the flash
6- Flashing:
Open Odin and set up the file recomended by unlock client software on the Odin ( i used v3.13 version) AP section. Let Odin software do the rest. Voila you phone has been flashed.
7- After flashed turn on the phone and plug it again into the pc
6- Set up and Run the Unlock client software again and voila this time the software is able to unlock the phone the message " Unlocked" should be displayed on the screen.
8- Recover to stock room
8.1 Download the files recomended by unlock client for recovery
8.2 Open Odin and set up all the files Ap, BL, CP, CSC (you got two option here if you select CSC home yo got the sprint logo back if you dont want it then select CSC file) and USER Data
8.3 Let odin do the rest and check if it pass
9 Voila phone unlocked
I used window 10 computer. As a reminder i did it for Samsung Galaxy S8 SM-G950U with the 6th version of firmware unlocked by Sprint
