Can't downgrade from pie to oreo - Samsung Galaxy S9+ Questions & Answers

I sideloaded the pie beta (CRKE) and found that some of my apps started to freeze randomly. Because of this, I want to downgrade back to oreo. After researching a bit, it seems like I need to use either odin or smartswitch to do so. Odin just fails (tried multiple times) and smartswitch says my device is up to date. Any suggestions/fixes?

You have to do the emergency recovery in smart switch

I tried that. In the emergency recovery menu, my device doesn't show up. Does it just take a while for it to appear or should it be instant?
Also, for reference, my s9+ is working, except for the apps that freeze

I think, you have to boot into download-mode for the smart switch recovery.
Also first plug in your phone and then open smart switch

1. Backup your phone using smart switch you installed on your computer.
2. Logout on your Samsung account.
3. Factory reset your phone.
4. Open smart switch on your computer and plug your phone.
5. Once your phone is connected to smart switch you will see the option to downgrade to the last official firmware installed on your phone. Good luck. Hope this help.

You have to turn USB debugging on in the developer option in your phone's settings.

Yes, I turned it on before I tried the other things.

Make sure to unregister from the Beta. Use the samsung Members to do so. You might need the Old Samsung Members or the UK version. The US version was crashing on me after I installed PIE.
Open up Smart Switch on your pc and make sure to install smart switch from the play market on your phone before you plug it in.
Once that is done plug your phone and you should see your s9+ on Smart Switch (pc) and it will say something about downgrade update available.
Good luck

Thanks for the reply. I actually couldn't sign up for the beta the official way (I have Xfinity Mobile) so I sideloaded it. I'm not sure if it will work but I'll try it anyways.

I switched to U1 firmware and got the beta using the app and registering (Also on Xfinity). I did try doing a downgrade using smart switch and it was quite painful and once i finally got it to downgrade it looked like it had destroyed efs so no radio. But I was able to get the full firmware for xfinity and an Odin that works to downgrade and or switch to U1. Let me know if you need links for either.

Yeah, it'd be awesome if you could send the files over. Also, which version of Odin did you use?

I'm on SM-G965U and was able to downgrade without a problem but I had to use a patched odin to do it

[Q] Major issues all programs stopping!!!!

When I turned on my i9300 galaxy III phone last week it prompt me for an upgrade. I installed it and as soon as it booted again, every single app started to issue warnings about stopping. The phone cycles through all of these pop up warnings over and over again and never reaches the home screen.
What I have tried:
Plugged it to PC open Kies - drivers were not installed correctly, Kies didnt connect.
Ran troubleshooting (unplugged phone b4) connected phone again Kies didnt connect.
Restarted the phone in d/l mode --> wipe data/factory reset, this time the drivers were installed correctly but Kies didnt connect again.
Unplugged phone open Odin and it didnt recognize the phone either.
Tried 2 different cables switched USB ports and nothing!!
PC recognizes the phone but it wont let me see content in windows explorer.
Please help me, thanx in advance. :crying:

seems you need to get on another Rom
why not try odin
or root and get CWM and flash a custom Rom

I cant root the phone or how do I install another ROM. Odin doesnt recognize the phone, I plug it in and nothing happens
so I have no options how to connect to the cell phone.

For ODIN to recognize the device you must first go into Download Mode and you need to shutdown the device first then do this hold home+vol down+then power button)
You don't need root to use ODIN though. If you want to revert to stock see the instructions here: http://forum.xda-developers.com/showthread.php?t=1646610 it's pretty straightforward anyway so i guess you won't do something unnecessary.
As you were upgrading legitimately, take it back to vendor or Samsung and get them to sort it

Yes I did that, I said that in my first post. I put the phone into d/l mode but Odin doesnt recognize the phone, that is my major issue here.
Neither Kies nor Odin recognizes the phone. PC installs drivers correctly and knows when its plugged in but thats about it

There is no Marshmallow yet. And Kies doesn't work anymore, you can use Smart Switch now, to update or restore phone.

Marshmallow update

Dear All,
I have recently purchased s6 edge plus verizon phone . I tried to update my phone from lollipop to marshmallow but i am not able to update it. I am using T mobile connection in this cell phone.
I tried to use smart switch to push the update from lappy to phone. It didn't work out.
Also tried to update from phone directly, it didn't work out.
Could you please sent me any link or steps to proceed further.
Did u get through this.

Please follow the instruction here to update your verizon device.
http://www.verizonwireless.com/support/samsung-galaxy-s6-edge-plus-update/
To install upgrade assistant on your pc, just plugin the device with USB, popsup with install software, do it and open application. Re-connect the device to check the updates and install. I've followed same instructions with no data loss.
Worked great for me. The only problem I had was the phone kept popping out of software installation mode into mtp mode. I eventually realized that to get it to stay I needed to keep the phone locked while plugged into the USB drive.

LGH831 Downgrade to Nougat

Hi,
I have the LG G5 H831 unlocked, I was having Nougat since I got it and it was working just fine.
Few days ago I got Oreo Upgrade, it's nice and smooth but only but only problem is that for an unknown reason my mobile data is not working anymore. I tried everything I could, resetting the phone, removing APN and add it again...
I'm not familiar with flashing the LG, I used to play with Samsung, so do you know if I can downgrade to Nougat? if yes, with what tools and from where I can get the firmware.
Thanks

Can you try simply to find modem zip for your model and try to flash it, maybe this resolve yor mobile data problem.
I finally succeeded to downgrade my phone to Nougat and Mobile data is working fine now. The download mode problem I had was only due to the cable I was using, I changed cable and it works, then I used LGUP to flash the Nougat kdz.
I don't know what was wrong with Oreo, I liked it but mobile data not working is not helpful.

You need to be more specific.
It's the H831 model?
Was it an upgrade from Nougat to Oreo?
did you reset your phone?
Do a hard reset and try again.

You are having which OS now? Nougat and it's working?
For my case it was working on Nougat but when upgraded to Oreo, I got no signal, I don't know why.
This doesn't happen to everyone. So I can't say.

Oh it should work, but I'll stick with Oreo, I believe it's better.
Also the process to downgrade is not straight forward, you need to have the right files for the right model and the right software...

It might be late but still......Follow these steps:
1) Turn on Mobile Data
2) Turn on Data Roaming (Yes it is the most important step)
3) Wait for few seconds
4) Once the data starts working turn off data roaming

Strange steps, mainly the roaming part
Anyway, I'm back to Nougat for now but if one day i change to Oreo and still have the issue, I'll try it.

My S9+ will not update anymore and I can't get Odin to flash stock firmware

I have Tmobile G965U on android 9 One UI beta build PPR1.180610.011.G965USQU3CSAB and when I try to update on the phone it says the software isnt supported. When I try to flash literally any stock rom in Odin it either fails or gets stuck at SetupConnection/Initialzation. Can anyone help me get my phone up to date?

Sounds like a firmware mismatch possibly. What does it say in Settings/About phone/Software information/Service provider SW version? Last line under your IMEI number. Mine is TMB/TMB/VZW. I think possibly the first to have to match for OTA updates to work. The last one indicates what the original firmware out of the box was.

Hmm that looks good. The OTA failure might be due to you having the beta firmware. There might be a series of beta updates you can install from here in the forums to get you where you need to be. I'm not a hundred percent sure though.
Otherwise you ought to be able to update via Odin if you download the latest T-Mobile release. Are you experienced with Odin, is it recognizing your phone when it's in download mode?

Odin wont flash any rom whatsoever. I've already tried 3 different versions but I gave up since they usually take 4 hours to download. Odin gets stuck and/or fails at Setupconnection or initialization steps every time. I'm only asking for help because Odin will not work. I figured I need an update for the beta. They only work for each build though so I need the build that updates baseband ZRL5

So the phone is being recognized in Odin(the little box that says com:x or whatever)? Sometimes it helps to try a different cable if you have one. it sounds more like a connection thing than an issue with the firmware?

You have activate developer options and inside OEM unlocked and usb debugging ? Or try to get back to android 8 maybe is possible because you have beta firmware.

Wouldnt even have gotten this far if I didnt have ADB debugging enabled. As I said before several times. Odin wont flash anything. I've already tried to go back to 8. If you can tell me how to get back to 8 without Odin that would be nice. But i need links to files not unhelpful text that tells me that I need to find something. Thats the whole issue. It's almost impossible to find the correct files unless someone who already knows gives you a link to them. I thought that's one thing XDA used to be good for but I guess that isnt the case anymore.
I would of helped but you kinda sound like a ****. Have fun with your perma-beta phone!

Download the update from this website then follow the instructions at the bottom of the page. This is the only thing I can think of if Odin isn't working

If your stuck on setup connection on Odin some things to try assuming using windows
Use Odin 3.13.1 ( or modified Odin 3.13.1B )
If you have smart switch/Kies install, un-install it.
USB cable i'm assuming is a data cable.
USB port try plugging into USB 2 port.
Plug phone directly into PC not any hubs.
Use latest Samsung USB drivers.
Run Odin in administrator mode.
Boot into download mode then reboot back into download mode again.
Maybe turn off any anti-virus programs.
Try a different PC.
These are a few things to try as failing at setup connection can be a common with some people and can vary with the PC.
Also note having OEM unlocked or USB debugging has no bearing when flashing stock firmware with Odin.
