S8 SM-G950F Stock firmware help! - Samsung Galaxy S8 Questions and Answers

Hi,
I cant seem to find anything related directly to the S8 and not sure if all mobiles are the same..
I had Android 8 on my S8 and needed to downgrade to 7 to try something, I did that but after it completed I had a messy settings menu where parts were duplicated or showing the wrong sub-heading.
I've read on the forums about this and it says re-flash with CSC and AP to fix.
When I try to re-flash it gets stuck on "Set Partition" in Odin.
I read to fix this you need to enable the "re-partition" option in Odin, I have tried this and it still does not work.
I have also tried full flash or AP, CSC, BL and CP and it's still getting stuck.
Tried on two different PC's (just in case) - same result on both.
The phone still boots and works, but it feels like something is wrong.
Can someone advise on how to completely re-flash the phone? The videos I've watched so far don't seem to run into this issue.
Any help would be awesome

Update: Using odin 3.13 gives this error: <ID:0/005> Can't open the specified file. (Line: 1892)
I've tried it with SamFirm and Sammobile FW.
EDIT - Finally fixed it, flashed G950FXXU1AQDG to the handset, wiping and re-partitioning the phone, after setup an OTA update was pushed for 8.0.
In case anyone else has the same issue, I used Sammobile for the FW and Odin 3.12 to flash.

[Q] Bricked SM-G900W8 looking for partition file

Hello, I am relatively inexperienced when it comes to flashing and have managed to brick my s5(rogers(SM-G900W8)canadian). I have looked around and it seems as though in order to get my phone to work I need a pit file for my phone. Problem is, I can't find one. If anyone could help it would be greatly appreciated. Thanks. by the way I have rooted and enabled usb debugging prior to being bricked
http://forum.xda-developers.com/attachment.php?attachmentid=2800218&d=1402859206
so that should work?
Well that's the PIT file for your model phone, whether or not it unbricks it depends on what you did to brick it
I bricked it by attempting to flash philz touch recovery in odin 3.09 and it failed. Now I have the message:"Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again." on my phone, I tried doing exactly that but kies detects my phone but never finishes loading it up. So I tried flashing the stock firmware for my device model and got the same issue I did when attempting to flash the recovery. As far as i know I didn't do anything wrong as i was very careful to select the right files, etc. but clearly I did.
Well you've got nothing to lose by trying the PIT file
Not flashed PIT before so read up on exactly how to do it first, this is the thread I got the link for your phone from
http://forum.xda-developers.com/showthread.php?t=2737448
Tried flashing the file and that failed as well... not looking too good.
I guess my phone's useless now.
Did you check the "Re-Partition" in ODIN?
Are you using the latest version of ODIN3 (3.10.6) ?
Try ODIN3 version 3.0.7 too
(Obviously) Got phone in download mode
Tried just flashing a stock ROM from sammobile
Tried flashing the stock ROM along with the PIT file & Stock ROM together?
tried it all, when trying to flash the pit file as well though it gives me "SECURE CHECK FAIL : PIT" on my phone. whenever I try to flash it it always fails at system.img.ext4 with Complete(Write) operation failed.
I think I know the issue now, I'm using VMware, which apparently doesn't work. Will try on a windows pc in a while. thanks
Ah right, yea always best from a native PC
Let us know if you get it working
It worked and then I installed the newest cyanogenmod.

How do I unroot and reflash stock ROM onto AT&T G930A S7?

I am trying to unroot my phone. I have a US version of G930A. Sammobile has every county except the USA. I found G930AATT1APB5_User_Binary.zip which has AP_G930AUCU1APB5_CL7193387_QB8719495_REV02_user_low_ship_MULTI_CERT.tar, the BL, CP and CSC file in it. I try to flash it using Odin3, and I get an "odin protocol version error." I take it because the image is a lower version that's what's on there. I would like to download the latest stock image but sammobile doesn't offer images for the US? Or is there a better way?
Wrong forum. This here is for SM-G930F Development, not Q&A. You'll get the answers you're seeking and more, at the S7 AT&T Q&A and Dev forums. Mod, please move - thanks.
Wrong forum. But try using Kies in Download mode
That is what i do when ever i restore my phone.
No Kies good lord. This isn't a Note 2.
You're getting that error because you're on newer firmware than you're trying to flash so it's erroring out.
Follow the Return to stock procedure in this thread:
http://forum.xda-developers.com/ver...sed-unroot-t3411039/post67605246#post67605246
Flash all 4 files, then you'll be on PF2 and able to get the OTA Update to PG1 with wifi calling, etc.
I tried using kies. It asks me for my model. I put in SM-G930A. The serial I put in all caps and it tells me my model number I entered is wrong.

Which Odin are you using?
You're flashing the PF2?
I've tried many versions of Odin v1 (not the 3). I'm not sure what the PF2 is.
To get it to work, I just defaulted the phone and rerooted it. It's the only way I can get it to work. It's working perfect right now. Only question is how long,

for g930a (galaxy s7 at&t NOT EDGE)
WARNING: YOU WILL LOSE ALL DATA MAKE A BACKUP
download these files:
Odin: http://www.mediafire.com/download/2t...din_3.12.3.rar
Flashing Files: https://drive.google.com/file/d/0B17...w?usp=drivesdk
After downloading extract the .rar extract it then extract each, BL, AP, ect... files. Use the odin included in the download to flash and you will be returned to stock. If the odin included still gives you the error you can get the princecomsey version and see if that works from here: http://downloadandroidrom.com/file/tools/ODIN/ODIN-modified.zip
If odin freezes or crashes just restart it and try again, it might take a while foor the AP file to load into odin so just be patient and if it looks like it is about to crash wait about 2-3 minutes then force close it and try again.
Now you are returned to stock an all set !!
(p.s) - PF2 is the latest firmware as of now for the g930a, meaning when you flash this you will be all set. You may have tried to flash the original PF which is now outdated cause AT&T updated it, I did this and it worked but i could not update my phone so I flashed this one and it works perfectly and Samsung pay is up and running.

Can't restore G930P Firmware

Ok so here's my issue
For a very long time since the G930U firmware was available to install, I've been using that. Well I decided to want to get my phone unlocked for GSM using those services but it needs Stock Firmware.
So I tried to restore to the latest G930P firmware and ODIN is giving a Volume size error for the system.img.ex4. I've tried now a couple different firmwares and no luck. Any idea?
The latest Firmware is PH7 I don't recommend it. PG1 on down are good to go. Extract zip stock firmware to a folder and add it in to Odin all the slots accordingly. BL AP CP CSC the last slot CSC is HOME_CSC not CSC_SPT and start flashing. It always works for me.
I ended up figuring it out. I had to find the stock G930P .PIT mapping's and re-partition because G930U ended up changing the sizes.
Oh good to know. Thank for sharing
Why do you not recommend PH7 update? I've heard it helps with battery life.
Could you share the pit file you used. I tried the same thing with a pit file i found online how ever since the pit i am able to flash bootloader but unable to flash system.ext4. Odin gives me a "failed (auth)" and neyjer the 930u version or the f2 or any of the other stock roms wont flash.... Help please
Don't you just love it when people "figure it out" and then don't share how? lol
Here... Since nobody gave you this. This may not be your problem.

[SOLVED] How to downgrade S7 Edge SM-G935FD from android 8.0 Oreo to Official 7.x?

Hello, I have recently installed Android 8.0 (Unofficial) on my S7 edge as mentioned in this thread by ProtoDeVNan0. And also installed TWRP recovery as explained here to upgrade it. After installation figured that it has some issues with some features.
So now I am trying to downgrade to the latest official firmware.
But every time I download and install the official firmware zip file using TWRP, it says the zip file is corrupt. So I tried downloading from different sources and still it says it is corrupt in TWRP.
And then I tried using Odin after extracting the Zip file. Using the tar.md5 files inside it. It fails as well.
And also found no way to install the official recovery.
Is there any way I can downgrade from 8.0 to official 7.0? And also I would like to remove TWRP and install official recovery. Basically returning it to its original state.
Searched a lot and found no possible ways to do so.
Please help. Thank you
SOLUTION:
I have found the solution to the issue.
I previously tried using odin to load all the packages in the zip file all together which was the reason i was getting the error.
The solution is to tick and select AP file only in odin and start.
(in case stuck at meta-data unplug)
Then reset odin and re-start the phone into download mode again.
Now tick and select the CSC file (not HOME_CSC), and then start.
After the phone reboots, a factory data reset will occur and phone boots up.
Why are you using TWRP to attempt to install Official samsung firmware?
You do it all through ODIN, it'll put your device back to basically original setup state with stock firmware. Flash with CSC and not home_CSC, I assume you have no data you will need to backup before hand.
More info here:
http://updato.com/how-to/how-to-install-an-official-samsung-stock-firmware-using-odin
Which Version you use odin? I try your solution but dont work on my g935f?
BL not downgraded!

STILL NOT DOWNGRADED!!
You can apply the solution described above (using ODIN to flash AP, CP and CSC with a previous version of firmware). However, the Boot-loader will remain under the latest version (since January 2018 update).
The problem is drastically worst for those who used to patch certificates before the January 2018. For those users, I will advise to not install the update from January 2018 because, they will not find any tools currently available to patch certificates and get the phone work a new. They can try but it will not be successful and the phone will keep saying "Emergency call only" or "not registered on network".
Anyone having successful experience to inform others please!
Thank you.

Yes it Solved. You Need to have Stock Firmware of March , and extract PIT File, then flash Firmware with PIT File.
In Options tab check "F. Reset Time", "Auto Reboot", "Nand Erase", "Re-Partition" and "Phone Bootloader Update". Rest options must be UNCHECKED!!!
If anyone need Firmware of March for G935F and the PIT , then let me know.

after trying for many days got this Solution.
The baseband should be same or higher of the firmware to downgrade.
Example: G935FXXU2DRAG Oreo
G935FXXU1DRAG Nougat ( will not happen.)
Both should be same I mean the U2 in the middle.
Or u can downgrade upgrade from U1 oero to U2 Naugat. But not from U2 to U1 Baseband.
Hope it helps.
Just download last nougat release and flash it using latest odin simply guys,
I have tested, no one needs to use pit file or nand erase etc. Use samfirm to download latest firmware for your model. Then use latest odin to flash. Be sure to use normal csc file, NOT the home csc. You don't need pit file when using normal csc, its included with it.
If you used twrp recovery etc to flash unofficial oreo releases, you need to first confirm if oem unlock is enabled, don't tick on auto reboot option, just tick F.reset from odin options, then first flash latest nougat for your region through odin, then flash twrp through odin. Then when odin says pass, force reboot into twrp recovery from download mode, then format data in twrp and flash super SU/magisk and no verity opt encrypt. Then reboot and you will be good.

can't downgrade
odin gives "FAIL" when starting the procedure.
i have the U1 nougat version and the U2 oreo version.
can't seem to find U2 nougat ( if any) and I guess upon upgrading to OREO sonething had changed and can't downgrade anymore.
I managed to get into android recovery and did a factory reset and total wipe but nothing, through ODIN flashing doesn't work.
Any ideas anybody ? I really want to downgrade so I will be able to install stock nougat, and flash an oreo custom ROM with magisk in order to get around the KNOX triger thing.

You can't flash U1 nougat on U2 oreo firmware. It has been all over xda that U2 firmwares has Version 2 bootloader which can't be downgraded to Version 1 bootloader of U1 firmwares. Nougat has many U2 firmwares, you simply need to search..

bluetooth start works but need switch off battery optimization
Hello everyone
I found it!!!
Problem with your bluetooh connection after upgrade can be solved in one of the way follow previous post or "disable battery optimization.
I try before swichng off and on all networks, emergency mode etc. and nothing happen.
Disable battery optimization
Sometimes battery optimization also messes up with Bluetooth connections. I suggest you check battery optimization settings and remove Bluetooth from it. To do so, follow the steps:
Open device Settings and go to Battery. There is few ways to go there:
first can be: open settings go to "device maintenance">>>clik on "battery">>>clik on "batterry usage">>>clik on 3 dots right top corner>>>then clik "optimise battery usage">>> and u are there - swich off “Bluetooth MIDI service” and apps that you use with Bluetooth such as Play Music, Phone, youtube, maps etc.
2nd
open settings Tap the 3-dot menu present at the top right corner and select “Battery Optimization”.
Turn off Battery Optimization for “Bluetooth MIDI service” and the apps that you use with Bluetooth such as Play Music, Phone, youtube, maps etc.

Galaxy S7Edge G935F UK

I have a Samsung S7edge G935 that had boot problems and I have been trying to flash with the standard firmware from Sammobile and also Frija. I could not get either firmware’s to flash with Odin in windows as I kept getting Pit loading errors etc etc. As many know Odin for windows takes forever to report an error so in frustration I wiped the nand thinking that I could reinstall a nandroid backup off an identical phone I have. Clearly I was wrong. I have found on this forum the FWUL application which I have working and although I have not yet succeeded in flashing the firmware it does at least give the error messages in an instant. The firmware’s from Sammobile and Frija are correct for the phone UK BTU and I have unzipped the CSC files to obtain the PIT file which I must assume is the correct one for the rest of the firmware. I still get the same error in jodin ‘ pit file corrupted would you like us to get the correct file for you’ but there is no obvious way to accept the ‘offer’.
