S6 SM-G920I Downgrade from Nougat to Marshmallow Help - Galaxy S6 Q&A, Help & Troubleshooting

Nougat has been terrible for me since the OTA upgrade. VERY laggy...quite often, like almost constantly, lags of 5 to 15 seconds to do anything (scrolling, swtiching apps, clicking a button, etc). It is pretty much unusable. So I want to go back!
However, though I've done ROM flashing on earlier phones, it is not something I do often, so need a bit of help. I know the basic process, but trying to understand which stock firmware to flash. I see them here for the 920i (sammobile com/firmwares/galaxy-s6/SM-G920I/)...but no US region. I suspect because I bought this as an unlocked phone...it was from another region. I am in the US and have ATT as my provider. So which firmware version specifically would I flash...thinking Australia...just because it would be in English...but can only one point me in the right direction?
Thanks a bunch,
Chad
PS: Ive tried to troubleshoot the issues in nougat a bit, but without much luck...I've seen to turn off animation, no help. Run in safe mode...seems to run ok, but then its running none of my apps....I suppose I could install all my apps, then reinstall one at a time...but that would take more time than I have. Any other suggestions...I am open!

Anyone? This phone is driving me nuts!

Don't do OTA updates, they only Layer actual system installed, always perform a clean update from an original firmware file.

First Download an app called: PHONE INFO SAMSUNG. Open it and check your original CSC code. Once you find this, go to updato.com enter your model number and select your CSC in filters. Find the FW you want to download and download it.
Once the firmware had downloaded extract it. Download Samsung Odin and open it up. Make sure you have Samsung USB Drivers installed. Select AP in Odin and select the previously extracted file. Wait for it to check the md5. Wipe your entire phone including Internal Storage. Put your phone into Download and hit Start in Odin.

[Q] Tab 2 10.1 touch screen stops after a couple minutes

Ok guys, almost first post here, now that its in the right spot. My galaxy tab 2 10.1 model GT-P5113TS is having an issue that I can't seem to find on any site including this one.
Little background, this problem first started several months ago. My wife ran the battery completely dead on the tab, we didn't have a "samsung" charger and couldn't get it to charge up. Bought new charger, got it charged, and ever since then, the screen will work for anywhere from 15-20 seconds to 3 or 4 minutes, then just stops working. Hitting the power button will turn the screen off, hitting it again brings up the lock screen, but the screen will still not recognize any touches. The side buttons still work, just not the touch screen.
Letting the tab sit for a couple hours is the ONLY thing that gets the touch screen working again. But it will only work for a minute or two again before it stops working... again... I tried a soft reset several times to no avail. Kind of forgot about the tab, left it for a few months. Picked it up yesterday after charging it and still no different than a couple months ago. I tried the factory wipe/reset several times using the power and volume buttons and it made no difference. Usually the screen won't stay responsive long enough to make it through the whole set up process.
I'm pretty new to digging into these things. I'm not afraid to give it a shot, since the thing is useless in its current state. But most of the lingo and abbreviations are new to me. If anyone can point me towards a solution, I'd be VERY grateful! I'll do my best to answer any questions to help as well.
PS, we bought it used off ebay, so no warranty. It worked fine for almost a year before this started.
Bump for a little help? Thanks in advance! :good:
Edit: Should also mention that it's 100% unmodified/stock. I haven't rooted it or been inside it or anything. Very open to trying about anything since like I mentioned, it's useless to me as it sits currently.
You can't do much with the screen the way it is, your best bet is to root and flash a custom rom.
Look in development for a root method and install a custom rom using Odin. Check out You tube for videos on the matter you should find several.

For me th einstalled custom CM11 rom nighlty boots but seems to drop all kinds of android processes. Ik keeps showing all kinds of zip files in the download area. Installed apps can be deeted but are back after reboot. Can't find sd-ext.
Installing stock of custom rom with Odin goes ok for a while but fails all te time.
Is there a low level kind of remedy?
Thanks!
Can you get into recovery?
Use any previous nandroid.
You do have nandroid b/u's ?

Yeah, I can boot into recovery where it gives me the options to install from SD card etc. And I have to use the power and volume buttons to navigate the options. Thats how I tried the factory reset the first time, to no avail.
I don't have any other backups or anything to try. Where would I go about finding something to use?
Your only option is to reflash your rom or the stock firmware in order to fix the issue.
Use Google to search for the stock firmware, you will have to root again and install CWM.

Is there an easy to follow how-to for rooting it somewhere? Ideally a way that doesn't involve using the touch screen, since mine is obviously on the fritz.
I'm assuming to reflash the stock files, I'll need to (figure out what files) save them to the SD card then select the restore from SD card option in the recovery menu?
I'm a noob to this stuff, so not familiar at all with the abbreviations and what not. (What is CWM?) But I'm fairly competent if things are broken down to the basic steps and what not.
Well looks like I'm answering my own questions a little bit, but it looks like I can download the VRoot program onto my computer, along with the Samsung USB drivers, and use that program to root the tablet..... correct?
Then download Odin to flash the files?
Not familiar with Vroot, need to look it up.
The first thing you need to do is flash the stock Samsung firmware in Odin (using download mode ) . Afterwards you run your tablet for a while, 2 to 3 hours and make sure it's OK (touch screen wise) , then you can root and flash roms.
Pp.
So I don't need to root it to flash in the firmware, just if I were to flash a rom? Sounds simple enough.
Next (noob) question. Does the firmware have to match with the version of android running on the tablet? I'm not sure what version is on it, I'll have to look after work. Or can I just get the latest firmware update for my model and use that? Looks like for my model there's a version 4.2.2 that says Canada. That seems to be the newest one out there. Is that what I'll want to use?
Follow this video and you should have success. They have an apparent source for the firmware, otherwise you have to download from Samsung and that can take days.

After watching video there are further steps to fully wipe and factory restore , you don't have to go this far unless you want to make tab new like out of the box.

Over the weekend I found a site that had the correct factory firmware, and I was able to download it, install Odin, and flash the firmware into my tablet. I followed the steps for the beginning portion of that video posted and was able to get it done. I then wiped all data and the cache and now I'm happy to report that its back to working like it should! Basically saved me from trashing a $200+ tablet!
Thank you guys so much for the help! And thanks to everyone that makes this site possible. Awesome to have people with this level of knowledge in one place and so willing to help!

Galaxy S7 Nougat Beta G930F (Would this process work for T-mobile?)

So I stumbled upon the files for the nougat beta program for samsung on another forum that I follow. I just wanted to share this and know if this could mean anything as in a modified stock nougat for our phone or possible even a bootloader exploint found in this beta. Read the original link first for more details.
CAUTION
User Maherk from the forum said this on the flashing matter:
"One issue that I faced while flashing the device, is that Odin kept crashing when the process gets to system.img, which meant that I soft bricked my phone.
If that happened to you, don't panic, press volume down+power button for 10 seconds, the phone will show an emergency message, stay there, and plug the phone and flash the file again. Don't go back to the download mode, just stay on the emergency screen and flash it.
Another thing to consider, the zip file you get might have 4 files, AP, BL, CS, and CSC. If it does, then make sure to rename the AP to .tar instead of the .tar.md5
Good luck"

I would've like to but I cannot as I need my phone for work. If someone would like to try this I would appreciate it very much but do be wary of risks that are posed with flashing Roms.
It will not work. It's like trying to put diesel in a gasoline engine.
I thought the same, this will not work.

Odin root flash not working

Hi guys,
Not started a thread on XDA for years but I really am stumped.
I have claimed my girlfriends s6 (SM-G920F) after she upgraded and intended to root it and maybe try a few Oreo ROMs etc. After investigation I saw that (I think this is right) I don't need to OEM unlock this version of the device and rooting via Odin is the best way to do it. BTW if I do need to OEM unlock then that might be the solution to my issue, so if some one could clarify that'd be great.
So a week ago I downloaded Odin and also my old favourite CF-AutoRoot after putting in the device details. The package was generated, I unzipped and put it in a folder in my desktop
After putting the device in download mode I run Odin as administrator and plug it in. The device is recognised and I get the blue box to show this.
I then click the AP box and select the image file and click start, everything runs as expected to this point and I get PASS displayed in the info bar. On the phone the progress bar looks like it has not completed and I can see a small portion still to run. On the first try I left phone like this waiting for it reboot for over an hour. I was expecting 5he device to reboot and get the android with the red exclamation point. At this point I restarted manually and saw during the boot process an error message saying Recovery not SE Enforcing in red.
I have read a few posts saying this can be caused by the wrong image being used, so I downloaded the Auto root package again and made sure that it was all correct, but the same thing occurred.
I have been looking and reading for the last week to find a solution, but I'm still in the same position. Can anyone help or point me in the right direction?
If you need any more info let me know.
Thanks in advance
Jon
im in exacltly the same boat pal. was running nanorom on my rooted s6, but had no vr capability and just got some galaxy gear goggles. tried to reflash arter97 kernal and lost my whole setup. ive been in and out of hard brick for last 24hrs and am back now to where you are, i can access download and recoveries via three button combo, but any packages i flash with odin just fail out right.
ive been here before though and usually get out once i find the right stock rom and csc's for my version. iof i find anything ill come back and share it with you pal.
Cheers mate, it's really frustrating. I'll keep looking too and post back if I have any success.
Hi guys, this thread hasn't been responded to so I thought I'd just replied to it to give it a little bump up. I'd much appreciate it if anybody could help me out here.
Thanks again,
Jon

Just try bro to reflash full stock rom again by odin and after flash it , reflash cf-autoroot again
also , can you provide more information about your android version and your csc stock rom ?
what a f**k about!!!!
Right then Jon,
sorry for my delay but not the greatest at reponding to things at the best of times, but with my own s6 in a right old state, and a 7y.o and 4 month old in the house, my pc time is limited.
anyways, im guessing you're a bit like me, and you've had your fair share of flashing roms and roots since the days of old! (Galaxy thru and thru for me s 1,3,4,6, plus tabs and watches).
this s6 gt-920f is a completely different kettle of fish mate. where you're at at the minute, if your still stuck in bootloop with no recovery, your gonna want to find twrp recovery, as you know mate, google will be your guide. you flash this just like a rom or the old cwm, download a zip, bang it in ap/pda in odin and let it flash. KEY NOTE IS MAKE SURE ODIN HAS ~"AUTO-REBOOT"~ UNTICKED, UNCHECKED, NO MARK IN THE BOX. THIS IS KEY TO THE RESTORATION PROCESS GOING FORWARD. Once odin shows that the file has flashed and passed, get ready to perform a three button power reset, Home button, Vol DOWN and Power for 8 seconds. when your pc makes the badong sound and the screen goes off, IMMEDIATELY SWITCH TO Vol UP, Home and Power, thus straight into recovery mode, AND WAIT.
You should see the blue and silver TWRP splash screen and then the recovery options. Firstly, wipe and format everything, dalvik, caches and perform a factory reset. twrp should ask you to type yes to confirm, do it, there's nothing there yet any ways. if you get any issues about cant mount data or some jazz, DONT PANIC, use twrp to reformat the partition to ext4, your pc should ping to show reconnection to the phone.
Now whilst still in twrp, nav to the reset options and reboot into download mode. if all has go well, the scren should have the regular greenish odin screen but without all the samsung odin mode in at the top. odin should show the phone as a connected device, you should be able to access your memory card from your pc to transfer rom zips etc and get the phone back up the way you are used to.
if on the other hand you want to get back to vanila stock style android, with the expense of a tonload of bloatware and crapps, you're gonna wanna take a goggle at stuff like "G920F Repair Firmware X.X UK YYY) , Where X.X is 5.1, 6.1, 7.1, depending on the original android version your brick was on, and YYY is your carrier or network operator, off the top of my head they are VOD, TMO, O2U, H3G.
AGAIN A KEY POINT IF YOUR GOING THIS ROUTE, THESE FILES ARE MADE FOR INDIVIDUAL MODELS OF S6 (THERES ABOUT 12 MODEL NUMBERS -YOURS IS AND ALWAYS WILL BE SM-G920F - SO DO NOT EVER STRAY FROM THAT NUMBER!!!! ) THAT MEANS YOU NEED TO BE FINDING FILES LIKE "G920XXU5EXUE 4 files repair firmwares", THESE ARE YOUR SAVIOUR. GET THE ONE THAT MATCHES YOUR PHONE AND CARRIER OR ONE THAT IS AS NEAR AS DAMMIT, AND AGAIN PLEASE MAKE SURE FOR THE LOVE OF YOUR PHONE THAT YOU ONLY GET FILES MARKED G920, ANYTHING ELSE WILL RESULT IN VERY SERIOUS ERRORS.
YOUR ALSO GOING TO NEED SOMETHING CALLED A PIT FILE, EASY TO FIND, LOOK FOR " S6 ZEROFLTE HIDDEN IMG FILE" IN GOOGLE.
USE OUR OLD BUDDY ODIN TO FLASH THE FOUR FILES YOU GOT FROM THE REPAIR FIRMWARE ZIP, WHICH ARE USUALLY LABEL AP, BL, CP AND CSC.. NOW TAP THE PIT TAB IN ODIN (IGNORE THE WARNING) AND NAVIGATE TO THE HIDDEN.IMG FILE YOU GOT AND BANG IT HERE. ON THE OPTIONS TAB YOU WANT TO TICK AUTO REBOOT, REPARTITION, and NAND ERASE ALL. i know, i know, you probably never use it out of some shear panic but right now its kosher.
start the flash and take a break. like a big break. the process is gonna wipe the phone in totalilty, rewrite every bit of code and software and reload like new after about forty minutes.
now, if it doesnt, there are a few things we can look at but am gonna leave it here and hope you can make some use of the ramblings of a lost man. my 6 is currently in an inverted touch bug where if i touch one side of the screen, the opposite side responds so its a proper nightmare, typing anything means that a becomes l, s becomes k etc. thisis down to me drunk flashing the wrong roms for and s6 edge, g925f, hence all my warnings earlier. anyways, i need a reefer and a scran after all this, God, allah, buddah i hope it helps someone.

Hi, thanks for replying.
I'm on the original stock, I've not flashed any thing just yet. To be honest, I'm not sure it'd work.
The android version is 7.0 and the build is NRD90M.G920FXXS5EQH6
Be glad if you have any advise.

if your not root yet just download latest your carrier/country firmware
from sammobile
and flash it by odin
but you are probably trip knox so you must root
so the steps you should do :
1-download your carrier/country firmware from sammobile
2-flash it by odin
3-flash cf-auto root to pass bootloop
or
download twrp recovery of g920f and flash it by odin to replace stock recovery then after flash it ,wipe delvik cash then flash su binary

Stock UK S7 Bootloop (Unrooted) Need help!!!

I've looked through the forums to identify a similar problem to mine in hopes I can resolve this issue but I've not found one. So here's my problem.
I have a UK Galaxy S7 running on the 6.0 firmware that came with the phone when it first released (Yes I know it's very old and should have updated along the way but I had plans to root and install customs at some point which obviously didn't happen). The phone is unrooted and the stock rom is the XEU version with Multi-CSC (according to recovery)
The phone was running fine until a few days ago when all of a sudden it shut off and wouldn't power on via the power button. So I pressed and held Home + Volume Down + Power. The green screen appeared and selected Volume Down to restart the device (as you do in odd situations like this).
PHONE IS NOW STUCK IN BOOTLOOP!!!
I have tried various means (not including flashing) to get the phone to boot to the home screen with no success. I have not performed a factory reset from recovery because I have various data, including pictures, music and other software on the internal storage which I wish to keep and not lose. The phone is still under warranty so I can take it to a Samsung repair outlet to get them to fix it for me but due to data privacy or whatever, they have to format it clean to then install the most recent firmware.
I've been scouring the forums for help on flashing OTA updates which retain data on phone whilst possibly allowing my phone to boot into the home screen so I can access my data. Is such a thing possible?
Any help would be greatly appreciated.
You can flash the latest firmware without losing data (as long as the hardware is not faulty) by downloading it from either sammobile, updato.com or using the samfirm tool here on XDA (Fastest option)
Then extract the firmware and add all 4 parts to ODIN 3.12.7 (Do not use ODIN 3.13.1 unless you want to flash BTU Oreo 8.0)
AP << (Takes quite a long time to add, be patient as ODIN will look frozen)
BL
CP
HOME_CSC
If you use CSC instead of HOME_CSC it will wipe the device after the flash, HOME_CSC will not wipe it
Put the phone into download mode (Home & Power & Volume Down)
Connect to PC USB and hit start on ODIN
Wait for the flash to complete (It can take quite a while) and the phone should hopefully boot back into Android
Thank you for the quick response.
It's imperative I get this right and ensure I've understood your reply correctly.
I have downloaded the following:
SM-G930F_1_20180417125627_cz5yqc22v0_fac - from SamFirm as it was much quicker like you said.
Odin3+v3.12.7 - This particular version was quite difficult to get a hold of. Various sites redirecting me to various pages without a direct link to download but I hope that is the correct one.
The firmware zip contains the following files:
AP_G930FXXS2DRDI_CL12365438_QB17789072_REV00_user_low_ship_meta.tar -------1
BL_G930FXXS2DRDI_CL12365438_QB17789072_REV00_user_low_ship.tar -------2
CP_G930FXXU2DRB6_CL648265_QB8952207_SIGNED.tar -------3
CSC_XEU_G930FXEU2DRB5_CL13061583_QB16917099_REV00_user_low_ship.tar
HOME_CSC_XEU_G930FXEU2DRB5_CL13061583_QB16917099_REV00_user_low_ship.tar -------4
I have labelled the files 1-4 in the order of flashing/installation (I presume?)
I will also follow your instruction of flashing HOME_CSC_XEU_G930FXEU2DRB5_CL13061583_QB16917099_REV00_user_low_ship.tar as this will NOT wipe any existing data on the phone?
Will following the above steps act as an upgrade to the phone and not wipe apps/pictures etc in the internal storage?
Have I missed out any other steps?

Almost, you must flash all 4 files at the same time, load them all into ODIN before hitting start, doesn't matter which order you load them in as long as they are all loaded before flashing
And you are correct with the rest, HOME_CSC will not wipe anything, and yes it will act as an upgrade although it is a full ROM you are flashing, to you the user, it will appear exactly the same as an upgrade as long as you use HOME_CSC
No other steps needed
I have loaded all 4 files as seen in the screenshot however, after clicking on Start, about 5 or so minutes later, it says FAIL in the first box above where it initially said RECOVERY. It's stopped and not done anything else.
I'm not sure what to do here.
I've also added a shot of the top left of odin screen

Yea it's failed, you can close ODIN and disconnect now
You can try doing it again, but that should have worked, you could try downloading the latest 6.0.1 ROM and flashing that the same way first, it looks like your bootloader is version 1 where this ROM is version 2 as shown by the S2 number in the middle of the firmware version

I've gone to https://updato.com/firmware-archive-select-model?record=0DB04AD4C34211E69215FA163EE8F90B
From there I've selected the most recent 6.0.1 ROM which is dated 4th December 2016. Problem is that the download is EXTREMELY slow and I have no idea how to use SamFirm to download that particular ROM.
I guess all I can do now is play the waiting game and repeat the steps with the 6.0.1 ROM once it's downloaded.
Thank you for your responses and I will post back here once the download has finished.

Yea unfortunately all alternatives other than samfirm tool are slow, and samfirm only downloads the latest ROM
Judging by the bootloader version and the ROM version you have chosen, if this also fails, then I would assume a hardware failure
The only other thing I could suggest if this doesn't work, is to pick an older version of ODIN to flash the older firmware, ODIN 3.11.1 was used for MM 6.0.1 ROMs if I'm remembering correctly
https://forum.xda-developers.com/showthread.php?t=2711451
or
https://odindownloader.com/download/odin3-v3-11-1
I've restarted the device and it said An error has occurred while updating the device software use the emergency recovery function.
I attempted to reboot the phone a couple of times to get into recovery and I was successful. I now see the the Bootloader version is now 2 as opposed to 1. After seeing this I attempted to flash version 7 as initially suggested yet it did not work.
I'm not sure how Bootloader changed from 1 to 2 and is still failing to flash in odin. I am still waiting for the 6.0.1 ROM to download, fluctuating between 16-19 hours as of writing this response. Once it's ready I'll try and load up odin 3.11.1 as a second solution and try 6.0.1, even though Bootloader says 2.

Your ODIN screenshot looks like it managed to flash the bootloader before it failed, so it's possible you are going to need to use a version 2 ROM from now on, I have the same phone, XEU G930F and it is running Bootloader version 2 (Running the BTU Oreo 8.0 stock ROM)
But if the 7.0 Nougat ROM failed again it's looking more like a hardware issue, seems to be failing when it should be starting to flash SYSTEM (AP)
You can try flashing the 7.0 ROM section AP on it's own with ODIN 3.12.7, see if that fails immediately, if it does that's likely where the problem lies, it's not unheard of for these S7's to fail like this out of the blue, I see it maybe a couple of times a month on XDA
Only solution is to get the mainboard replaced
But yea, give 6.0.1 a shot anyway, worth a try saying as everything else has failed up to now
(Looking for mirrors for that 6.0.1 ROM, I've got it on my main machine but it is offline right now with no graphics card so I can't access any files, stuck with a laptop, I always download and save every new firmware release for this reason)
There is Samsung SmartSwitch software for Windows for the emergency firmware recovery, but it WILL wipe your phone back to factory and delete all your data (Last resort if nothing else works, although if ODIN doesn't work, I'd say hardware failure)
Right so I've managed to download the most up to date 6.0.1 ROM and attempted to flash it with ODIN V3.11.1 and it idles at the recovery.img part and fails like the previous efforts.
I'm not sure if attempting to get OREO running with the latest ODIN might work? If not then I may have to give up and do a factory reset through Samsung SmartSwitch.
It probably is a hardware failure as I had noticed the lightning bolt appearing when the phone is off whilst plugged in the charge, it take about a minute or so for the percentage bar to appear, usually it was about 2 seconds before this disaster occurred.

Worth a try flashing Oreo, BTU on samfirm tool will give you it for the G930F
If you're seeing problems with the charging now, you might get lucky and find the USB port is the only thing needing replacing, but if you send it off for repair it's unlikely even if that is the case that they won't just charge you for a new mainboard, you can likely get USB ports from eBay but opening the S7 isn't as straight forward as the back is glued on for IP68 water resistance and needs a heatgun to remove, not sure if anything else like the screen needs removing for USB, I've not opened mine
You've tried a new USB cable and a different PC too ?

The charging issue occurred immediately when the phone shut off by itself and wouldn't power on conventionally. The phone is still under warranty so if the Samsung SmartSwitch software is unable to recover the phone then I will take it to the repair center and have them fix/replace it. If it's a case of undoing the glue and whatnot then I'd rather they give me a replacement.
I did change the USB cable to a different one, and I've attempted to flash the 2 different ODINS with the 2 different ROMS on a laptop as opposed to the desktop I was using. Still fails at the recovery.img part of ODIN.
I'm going to try Samsung SmartSwitch now and see if this will give it some life. If THAT doesn't work then it's 100% hardware issue and my data was lost to begin with.
Considering both versions of ODIN didn't work with either ROM, I don't think I'll be looking for the BTU version of OREO to attempt to install with. If there's a direct download that's quick I might but I think I'll attempt to Emergency Recover through the Samsung tool.
I want to thank you plenty for your help and knowledge on this. It certainly has been helpful and given me better understanding of the problem I'm facing and potential solutions. I have a feeling that the SmartSwitch recovery won't work either and still be posting back here hahaha.
OK I've got bigger problems on my hands now.
SmartSwitch and Kies both say "SM-G930F" does not support initializing. Please contact our service center.
I've already inputted my serial number and it gives me the same message on both programs. When I called up customer support they said my warranty is till the end of May this year.
Would the service center be able to solve this problem?

Yea I'd get it repaired under warranty asap then if it runs out soon, they will most likely replace the mainboard I'd say, which means 100% data loss as the storage is on a chip on that board, or might even send you a new S7
Really does sound like hardware failure if all of these recovery options have failed, just keep quiet about what you've done to try and fix it, just act dumb and say it won't turn on or they could claim you nulled your warranty messing with ODIN
And no probs, that's what XDA is all about Let us know how the repair goes and buy a MicroSD card to save your important files to this time so you don't lose anything if it happens again

I had an SD card inside with all my pictures I took whilst in Japan (Thank GOD!). I took it out when this issue arose to avoid potential data loss there.
As far as ODIN is concerned, warranty still appears intact but yes I'll keep hush hush when I'm there. I believe they said they'd give me a refurbished S7 if they couldn't reflash it there.

Yes, ODIN will not void warranty if you only flash stock, but telling them you used ODIN might, it's not a tool meant for us, it's Samsung's internal flashing tool not meant to be leaked online, sometimes they'll use any reason to blame you and not have to pay out / replace it so yea best not say anything other than official recovery methods suggested by Samsung themselves, if anything at all, I'd just say I didn't do anything, an OTA update came through and it never rebooted or something
Good job with the pics, I don't save any media to the phone itself, I create folders on the SDCard and move it over if I can't have it save there automatically, that way wiping the phone is nothing but a pain to set back up again, nothing actually lost

I'm going to give flashing one last try.
I am currently downloading Android 8.0.0 for United Kingdom (BTU, NOT XEU). I have to head to work in a few minutes. When I get back I'll attempt to flash that without BootLoader as that will change it to version 3 and you can't downgrade from that from what I've read here and there. If that fails then it's off to the repair center. If it's some sort of hardware failure then it won't flash regardless what stock rom/ODIN version I'm using.
Not sure if BTU update with home CSC will retain my data (assuming it works)

Your CSC will remain XEU as it is Multi-CSC containing BTU, and BTU contains XEU, I'm running it now with BTU firmware & XEU CSC
Bootloader for this Oreo 8.0 BTU firmware is still 2, with it being a new Android version you'll need to flash the BL too anyway

I've had no luck flashing it with Oreo. It's definitely going to the repair centre. Such a shame.
I'm very grateful for your time and help with this. I will report back this weekend with the results of what the repair centre will do regarding the device. Don't like to leave a thread without an end result.
Many thanks again!

Is this bricked

I seem to be in and endless loop of hope and despair with my Samsung Galaxy S7 - can anyone shed any light on this?
Long story short, I was on Android 8 and wanted to roll back to 7 (using a ROM I took from Sammobile) because I needed a previous configuration of Google Play Music for my Smart Watch to work. I used Odin to flash the phone and it declared the procedure as FAILED. Now I can't seem to even flash it back to version 8. It is just stuck on the below three screens, no matter what I do.
At this point I would happily just upgrade it to whatever firmware will work and not have a £500 brick on my hands!
Please note the images are at h t t p s ibb.co slash the below (sorry this forum doesn't allow me to post them as links!)

OK i've seen them, don't panic.
What region / country are you
What network are you on?
p.s. YOU CANNOT DOWN GRADE OFFICIAL FIRMWARE
I'm with O2 in the UK.
I'd be happy just to get anything installed on it at this point. At least then it's useable.
Whenever I try a new flash (even with Oreo obtained from Sammobile) it just gets nowhere. The COM shows connected (I have the USB drivers installed and have ditched Kies) and I browse to the extracted AP file then click start it either goes away indefinitely not showing failed or success or (with another AP file e.g. for older firmware) it just says Failed.
Thanks very much.

Ok you have to down load the firmware that was on the device from O2, so download O2 Oreo from sammobile or the unbranded BTU firmware and flash with Odin. This should give you access to the device but the google account needs to be bypassed and then wiped by following this method https://www.progeeksblog.com/frp-bypass-apk/
Ok I'll give that a go. Wow pretty detailed guide there. I've not heard of the frp bypass requirement. Another thing to get my head around. Why can't phones just be like PC's. Image them, clone and be done!
Thanks again will let you know how I get on.
Restoring to the BTU firmware posted here forum.xda-developers.com/galaxy-s7/how-to/galaxy-s7-flat-oreo-firmware-download-t3785309 worked! In my case I didn't even need to run the frp-bypass-apk. Turns out that my phone was restored to exactly as it was before I attempted to downgrade so I even have my data back.
Thanks so much for helping me out!
Brilliant. Now to save yourself a world of pain in future turn on OEM unlocking in development options.
Just a couple more questions if you don't mind?
1) What is OEM unlocking
2) Do you know of any way to "roll-back" my version of Google Play Music? I am currently running version 8.14.7427-1H and would love to return to an earlier one since it handles the Android Wear playlist differently.
Thanks!!

Well there's some settings on the phone itself which, when you mess up trying to flash etc makes life a whole lot easier to bring your phone back to life. A good explanation of OEM is here https://www.quora.com/Whats-an-OEM-unlock-in-Android
With regards to rolling back Play music yes you can almost always roll back an updated app either by uninstalling the update via settings>apps or finding an earlier version of the .apk file online by simply searching for it in google.
When downloading .apk files, to be able to install you have to enable "install from unknown sources" settings>security>unknown sources.
Hope this helps
Brilliant. Thanks I will give that a go.
