According to Sprint customer service they made the change when they upgraded to Pie. They also said they have no plans to change it back so it looks like Wifi calling will forever be broken unless you have a cell phone signal when you try to use it. It was the dumbest thing I have ever heard of. Most people that are using Wifi calling are using it because they don't have cell service where they are. If I had known that was the case I never would have upgraded to Pie and just stayed on Oreo. I am not sure if this problem is exclusive to Sprint devices.

When I flash the Combo Firmware the phone reboots into Factory Binary Mode and gets stuck there. If I try to run Reboot_EDL it does nothing. It seems that my computer wont even recognize my phone and it will only come up as "Unknown Device" in the device manager. I have no idea what I am doing wrong. Everything says PASS in Odin when I flash it. How do I proceed from here
[Samsung Galaxy S8 Guides, News, & Discussion] dewbieZ:
It's probably not getting stuck there, you probably aren't giving it enough time to boot. The first time I booted into the factory binary mode it took like 5 minutes

I was able to run G950U_recovery. I typed in the port and it appeared to start working, but then it hung for about 10 minutes and then said "Device not ready" and failed. It said finished, but I don't believe it actually finished correctly. When I try to run recovery again it fails as soon as I type in the port number. It says "'emmcdl.exe' is not recognized as an internal or external command, operable program or batch file. Finish!!"

I got it. I don't know how to follow instructions. Only issue now is I can't flash a 7.0 system su and combo boot image. Well no option to flash to boot partition. only system

I can. But it won't boot into that system for root. My backup wouldn't restore. But I'm like the title says?? I'm on pie with safe strap

---------- Post added at 07:30 AM ---------- Previous post was at 06:45 AM ----------

Yeah I flash my system brb1 then su and have to use the eng boot since safe strap won't let me flash the combo boot img. It only reboots to safe strap. Humm. So I can root. And flash everything for root. But at this point in time no root will boot

I'm on a v6BL and am able to get my device to show up in device manager as Qualcomm 9008 with a port, but when I run G950U_recovery.bat it hangs for hours. I have tried running the recovery file in an elevated terminal an have wiped data & cache in default recovery.

I think I swear it's PC based. I have 4 pcs laptops in the house and this and actual edl recovery only works on one of them. No matter if I transfer drivers from one to the other. Still won't work. Edl detects. But won't flash except on my oldest crappiest pc

Is it still possible to push a rooted safestraped combo on rev 6? I can test. I cant stand pie?????.

Id rather root 7.0 i hate change. ???
[Samsung Galaxy S8 Guides, News, & Discussion] jrkruse:
Yes just replace the pie system img in the edl folder with a rooted nougat system image then when done flash the pie Bl file in odin immediately reboot back to download and flash the BL safestrap in odin. The reason you need to flash pie bl first is because you need to flash modems and non hlos and they must be pie and they are in the pie BL file so its just easier to have you flash it then the BL safestrap file which gives you the needed nougat bootloaders and boot/ recovery images to boot nougat. You can actually flash them together after edl process if you want too save a step. Just put pie BL file in BL slot and BL safestrap file in AP slot in odin

So im cheating at this one then. Im gonna take cyborgs sys img since its pre rooted and i dont have to do anything from there. Logical solution for a quick turn around ,.

---------- Post added at 11:33 PM ---------- Previous post was at 11:10 PM ----------

Well that wasn't so bad of a chore. I am now rooted Rev 6 nougat. Maybe. Hanging on boot screen a awful long time but I never factory reset. So technically I edl dirty flashed

---------- Post added at 11:52 PM ---------- Previous post was at 11:33 PM ----------

So any one following what I did was extract the sys img from cyborgs rom. Renamed it to system img instead of ext4.

I then replaced that in edl recovery safestrap folder

Flashed all that. Of coarse I'm using the zero out bootloader tar for quickness.

Reboot download mode. Flashed both the pie and eng boot as stated above. In parallel in single Odin flash.

Then a good factory reset and rooted Rev 6 cyborg rom.

I assume from here I can install safestrap and either run my personal setup and or other nougat or pie roms. I would also assume. Oreo is out the window since there if I am not mistaken no oreo revision 6 bootloader. Unless some one can trip the anti rollback on it some how.

hi, thanks for the works.

btw i just want to start flashing my S8 G950U. this would be my first time messing with this device.

i got stuck at step 1 or 2. i'm about to flash the combi file. but it always failed after SetupConnection or Initializing.

i followed the instruction clearly, trying usb 3/2, reinstalling driver, disabling driver enforce, using different odin version, using different laptop, different cable, enabing/disabling usb debug, removing lockscreen, etc.

but it never gets me anywhere, still stuck like before.

is there any clue as why this is happening?

In step 2 I used method C and my phone doesnt boot, just black screen. I tried to reboot to download but it doesnt respond at all. ADB doesnt seem to work either. What should I do?

Thanks
[Samsung Galaxy S8 Guides, News, & Discussion] jrkruse:
Probably should have followed those big red letters that told you not to use that method because obviously you didn’t know what to do. Did your computer recognize phone when screen rebooted to black screen. Did you run the recovery bat or did you just assume phone was broke because screen was black? Since you did what I told you not to do in instructions you are now forced to get edl to work. So you probably need to force phone to reboot if you hold the buttons long enough it will reboot to black screen again or let battery die then plug back into computer and try again
[Samsung Galaxy S8 Guides, News, & Discussion] El3ssar:
At first, I tried method B but when the phone went black screen my computer didn't recognize it, hence the Reboot_EDL.bat didn't work. Tried to force phone to reboot with no result, still in black screen and no adb or anything else. Please, I know I probably bricked it for good but I'd appreciate the help.
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
You need to get your pc to detect it. If not yes bricked until you do
[Samsung Galaxy S8 Guides, News, & Discussion] jrkruse:
Ok im not following you. You said you tried combo firmware first and the reboot edl bat and your phone booted too black screen. Thats what its supposed too do. Then you said you can’t get out of black screen. Then how did you flash the zero bootloaders method after you tried combo method if you could never get out of black screeen?

As before root on nougat is only possible. This method will still allow nougat with a bit of work. Explained a several posts back. And 80% will always be in play on s8 and several other devices using the permissive boot img needed for root.

I can't tell if it flashed or failed
[Samsung Galaxy S8 Guides, News, & Discussion] Keo-nii:
Some clarification please.

in regards with step 2 opinion B, is it flashed through Odin in (and this is a guess) AP?

as user -haiishq posted about the error, what i did was skip part of step 2 cause I was unsure how to flash the combo file and went to safestrap. From there got adb access (unauthorized) and now in limbo.

The goal i want to achieve it to have Dev mode turned on and get adb access so that Scrcpy can get access. The phone has a broken screen- Touch works but from a certain point down it is a blurry and solid color.

If Having Trouble With EDL

1. Do not use USB 3 ports

2. Disable or remove your Antivirus (because sometimes virus can block instaling drivers , ports or running flash tool)

3. Put your windows in Test mode

To put your Windows in test mode just Run As Administrator Command Prompt and insert one of the following command:

bcdedit -set testsigning on ( to enable test mode)

bcdedit -set testsigning off ( to disable test mode)

Or Disable driver signature

for Windows 7

for Windows 10 users:

After that reboot your PC .

4. Uninstall all flash program from your pc like MiFlash , QPST , Qloader ...

Use Revo Uninstaller for advanced uninstaling that clean leftover files and registry which is stored inside your Windows registry.

https://www.revouninstaller.com/revo..._download.html

After that reboot your PC .

5. Install Microsoft .NET Framework 4 download from here: (if you already have instaled skip this)

6. Install Minimal ADB & Fastboot 1.4.3 command tool download from here

So flashing following the steps in the first post I get Safestrap for Pie installed, great. However, it seems Safestrap recovery is only useable with Android Pie if the BL_ENG_BOOTLOADERS_SAFESTRAP_G95*U_V*.tar.md5 is flashed but then I can't get into the actual OS. I can only get back to the homescreen if I flash BL_G950USQS*****.tar.md5 and then I can't get back into the Safestrap recovery. Am I missing something here or is this proper behavior?
