[Q] - Galaxy Note 3 Q&A, Help & Troubleshooting

Morning all,
I apologise if this is in the wrong section but I am new to the forum and in a bit of pickle.
Around a week ago I rooted my lovely new note 3 to hopefully one day install some nice new ROM to get rid of the horrid touch wiz and actually see the full potential of the phones power. However, for some silly reason while I was using titanium backup on my phone I thought it would be a good idea to uninstall touch wiz thinking it would magically go back to basic android however it didn't. It is completely broken now, woops. The first issue I had was it would boot up and stick to the Samsung logo and just glow so I thought it would be an idea to install stock ROM via ODIN to try and revert it back to normal. Once I downloaded the correct stock ROM it was uploading through download mode however at the last minute it failed with a ext4 error which I think it means it's bricked? Not sure, completely new to this. I am now a bit stuck as I am not 100% sure what to do next.
The phone will only boot into either the firmware upgrade has encountered an issue, basically Odin mode or download mode. I have tried recovering it through kies however it cant connect to it. It knows it is there as it will start searching for it when it's connected however says it can't find it. It wont boot into recovery mode.
My phone is a note 3 SN SN-9005. The system status is custom, reactivation lock is off, Knox kernel lock 0x0, Knox warranty void 0x1 and write protection is enabled.
Obviously I would like to get the phone back to normal, I don't care if it has to be completely wiped and brought back to normal I would like it to just work. I've been an complete idiot and fiddled with something I'm not 100% sure on and I would like to not have a 600 quid paper weight hehe.
I have tried putting stock firmware back on but it always fails with an ext4 error.
I will greatly appreciate any help or feedback.
I have recieved some good feedback on this so far however I am unable to get it fixed properly.

[Q] Help! I keep digging myself further into a hole

I have a Samsung Galaxy S4, the Sprint version. I wasn't able to send or receive picture messages and I thought it might have something to do with my APN being wrong (I bought the phone on eBay and had it flashed to nTelos, my provider) but I wasn't able to edit the APN and nTelos was, as usual, no help. So I figured I'd just root it and be able to edit it then!
It was at that moment I stuck my shovel into the soft dirt and started digging.
Essentially, I believe my phone is without an OS at this point. I have tried using ODIN to put a recovery on there so I can at least do something, but now even ODIN is freezing up when I try and flash the Clockwork recovery. I am stuck on the Samsung S4 logo screen and while I can enter download mode I don't think I can enter recovery mode - at least, it hasn't been working tonight. I don't remember everything I've done to my poor phone, but it has to be hurting after the beating I've put it through. I originally tried to root it though I don't think I was successful because the Root Checker said I wasn't, though I'm not sure what I was doing wrong then. Things went downhill from there.
I've read through thread after thread hoping for something that would work, but I've given up trying to use other people's problems to solve my own. This is me saying "Uncle". I require assistance. Let me know what you need from me to provide me with the help I need.
Also - I have ADB on my computer and I think I have a basic understanding of how to use it, but since I can't enter recovery mode I can't do anything other than pat myself on the back for figuring it out. I think my first problem at this point is ODIN. I uninstalled KIES so that's not interfering (and don't even get me started on KIES - I installed KIES and it told me to install KIES3 which told me my device wasn't supported... which is crap because it's running Android 4.3 - or was before I got to it).
Thanks,
If you're sure the phone was on 4.3, then your options are limited thanks to Knox. You can only restore a 4.3 (MJA) based ROM to the phone via Odin, whether it is stock or custom. Easiest giveaway is if you see a line for "Knox" on the Download Mode screen.
At this point you should look in the ROM directory here for a full ROM (xxxxx.tar.md5), either MF9 (4.2.2) if it doesn't have Knox or MJA (4.3) if it does. If you cannot use Odin to put a full ROM on there, then you will need some more serious help.
Odin the stock 4.3 MJA OEM. Will return your phone to a stock unrooted state.

[Q] Phone rebooting randomly - help needed

Hey everyone,
So, I'm pretty new to Android having had the past two iterations of the Nexus 7 and decided to take the leap from an iPhone (which I had jailbroken) to a Samsung Galaxy S4 GT-I9505 LTE, which I bought unlocked and outright.
I ran stock TouchWiz for a while and then wanted to play, so installed FoxHound 3.2. This worked fine for some time, but then I started getting random reboots which seemed to coincide with listening to music on the device. After a while the reboots suddenly became more regular and it got so I couldn't even open WhatsApp without it either restarting or going into a bootloop. Usually, if it went into a bootloop and I tried starting the phone straight away it would fail, but if I left it off for some time it would start up okay, only to reboot again later if I used it for anything. I also noticed the battery draining quickly.
I tried flashing the device with various other ROMs - PACMan, Google AOKP, etc. - but got the same issue. Many times, the system would crash just when I first started to setup the phone. I finally determined the reason it was crashing at the initial startup was that it was when WiFi was being enabled. So, I ended up following a fruitless several hours of attempting to fix the WiFi using files provided on this page: http://forum.xda-developers.com/showthread.php?t=2192025. I tried XXUDMH8, XXUEMJ7 and XXUEMK8 all to no avail - I installed both the firmware and the WiFi fix files using Odin and thought I had it cracked, only for my phone to eventually reboot again whilst WiFi was not even enabled - it did take a bit longer this time though, admittedly, but it still rebooted and went into a bootloop.
So, I finally followed this page: http://galaxys4root.com/galaxy-s4-tutorials/how-to-unroot-galaxy-s4-and-remove-root-completely/ to completely return my device to stock TouchWiz, but still no joy.
I have tried factory resetting the device and wiping all cache from the stock recovery and from Philz CWM (which I had while using the custom ROMs), but this does nothing.
I tried connecting my device to Kies now that I have the stock TouchWiz ROM back on the device, but it is now rebooting even more frequently and I can't get in long enough to run the emergency firmware recovery. It used to stay up longer (sometimes indefinitely) when connected to the PC via the Samsung factory cable or to a power supply with the Samsung charger, but now it is even rebooting when plugged in.
I am extremely worried that my device that cost me nearly £600 a few months ago is bricked for good. I did (understandably) think that returning it to default would've resolved the issue, but even this has failed.

Hi and thanks for your reply,
I can boot into download mode - one of the only things I can do! - and it says 0x1 under KNOX WARRANTY VOID, so yes it is showing Knox void.
Just in case you need it, the full information shown on the screen in download mode is as follows:
ODIN MODE
PRODUCT NAME: GT-I9505
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
KNOX KERNEL LOCK: 0x0
KNOX WARRANTY VOID: 0x1
CSB-CONFIG-LSB: 0x30
WRITE PROTECTION: Enable
eMMC BURST MODE enabled

Hey Repulsa,
Thanks again. Unfortunately, this is what I did. I signed up at samfirmware and downloaded the file: I9505XXUEMK8_I9505BTUEMK5_BTU.zip
The only thing I did different was that I used Odin 3.07 and flashed using the PDA option, but I'm presuming this is the same thing..? After the bootloop, I went into recovery and factory reset, but still the bootloop occurs.
I have since managed to get into my phone after leaving it off for a couple of hours again and looking through the settings it says I have "Samsung" as the secure boot status and "Official" as the device status. The build number is showing up as JSS15J.I9505XXUEMK8 on Android 4.3.
Should I try anything else that you can think of?
Thanks again for the reply.

Yes, I'm afraid it does, and I have already done the wipe cache and factory reset, but no joy. I did it again anyway and on reboot it went back into the bootloop again, I'm afraid..

Ah FFS. My battery serial does start with BD and I was wondering if it was a battery issue, but didn't want to replace it if the fault was wider spread. I guess I may have to try this then..
I'm just flashing to MJ7 right now, but if it reboots again I will see about a new battery from where I bought it on Monday
And, as I forgot to say in the last post: thanks for your reply. If this fixes it, much kudos, my friend..
Yep. The flashing of MJ7 did not work. Maybe my battery is a dud as it went straight back into a bootloop at the Samsung logo.
Carphone Warehouse visit on Monday methinks..

you can get passed the samsung logo if you boot while your charger is connected to the phone, the battery might swell as well or is already bigger then it originally was
My phone has been randomly shutting down over the past couple of days and the only way I can get it to boot is to connect a charger/cable to pc. I've tried different ROMs and returning to stock. No joy.
I guess my battery could well be the problem

Definately the battery, dude
I was experiencing the same problems, and I observed that the battery swollen. So I replaced it and now the phone is functioning properly. Do not wait for the battery to modify its volume because you are risking to put pressure on the display and crack it. Beware.
Was, indeed, the battery
Hey everyone,
Just to let you know that I went back to Phones4u with the receipt from September (when I bought the new phone) and they filled out a form to request a new battery from Samsung and replaced mine their and then in the shop with a new battery from another Samsung Galaxy S4.
My old battery did, indeed, have a serial number that started with BD and the new one starts with AA so hopefully I am now sorted.
Massive thanks to everyone who replied and hopefully this thread will save someone else the time and lost data that flashing ROMs can incur.
Cheers,
A very happy Steve :laugh:

Note 4 Stuck in Boot Loop - Help - Recovery not working - Flash stock Rom not working

Note 4 Stuck in Boot Loop - Help
I have a Note 4 SM-N910F, never been rooted, stock rom upgraded to 5.1.1 back in October, working fine until yesterday when it got stuck in a Boot loop.
Not sure what caused it but before it got stuck I was messing around with Google Photos which was running a bit slow.
Also I put it on the Qi Charger just before the loop started. It has an aftermarket Fone charger stuck to the battery. I’ve had this and the Qi Charger for 6mths with no problems before now.
It gets to the Samsung page waits a couple of seconds then boots again.
Here’s what I’ve tried - unsuccessfully - to fix the boot loop:
1: recovery mode.
I can get the little recovery text to appear in the top left but after a few seconds it boots again.
2: volume down, home
This gets me to the screen with up/down for continue/cancel.
This is the _only_ screen I can get to stay up without rebooting. It sits there waiting for input.
- Cancel, causes restart, of course, but back into the bootloop
3: Mashing on power button. Banging it, wiggling it, blowing on it.
I read somewhere this could cause a boot loop, but I doubt it is my case because
a. I’ve never had problems with the power button before
b: When I take out the battery and put it back in, it does NOT turn on. If I do the same holding the power button, it powers into the boot loop. So if the button were jammed on I would expect it to never remain off with the battery in.
3: flashing stock rom
I’m not 100% sure what build I had before. I know it was stock 5.1.1 OTA, and I’m pretty sure it was unlocked (my wife bought the phone and i inserted my old sim, but she may have bought it from my carrier and can’t remember)
So anyway I tried all three versions of TPH (unlocked) 5.1.1 from Sammobile.
Installed Odin 3.10.7 and flashed them.
It reboots to recovery but immediately boot loops again.
I doubt its to do with the version of the rom anyway since the symptoms are identical after flashing. Only now the boot loop always shows the little ‘recovery booting...’ text in the top left.
Here’s what I have NOT tried but am thinking about:
A: Re-partition option in Odin
B: Nand Erase All option in Odin
C: Buying a new battery.
On A/B: as far as I can tell what I have done so far should have left the data intact. I’m prepared to wipe all my data if it fixes my phone (no lectures about backups please!) and I’m tempted to do one of these on the off chance that the problem is caused by data or the “disk" problems.
But I don’t want to brick it. Can someone recommend how likely these are to help
And what they actually do?
(Please refrain from responses I see elsewhere like “this will brick your phone if you don’t know what you’re doing”. I don’t know what I’m doing, thats why I’m asking - just the facts please)
On C: the battery seems ok in that the power is solid even after not being plugged in for a long time, but since it was on the Qi Charger with that aftermarket thing stuck to it when it happened, I’m suspicious. Can any one say if this is a likely cause?
If so, it might be worth waiting till I get a new batter before doing A or B (can I wait days for Amazon!?)
[UPDATE] Got a new (genuine) battery at a local electronics store. No dice. Same problem, so it's not the battery. Shall I go ahead and re-partition.
[UPDATE] Got a PIT file from another forum, and flashed again with re-partition checked and PIT loaded. same results.
Is Nand-rease worth trying?
The phone is still under warranty so maybe I can return it.
But in that case I want to erase what's on it first.
thanks for any help

I don't think that the Samsung service center will accept cuz u have unofficiall custom
Simple Go to ur any nearby SOFTWARE ENGINEER may be he will help u out
Even I had the same problem with my NOTE 4 EDGE
Try downloading and flashing any "COJ5" build of 5.1.1 from sammobile. Samsung has recently issued a new update "COJ5" it basically locks down the bootloader and will not allow the device to run any previous builds.....Maybe your phone updated to COJ5 in the background and then it started messing around because the phone is rooted. Flashing "COJ5" will lock your bootloader and you will not be able to flash 4.4.4 or 5.0.2 but there is nothing to lose when your phone is already pretty much dead?.....ORRR if this is not a software issue then it could be related to hardware maybe the memory of your phone is done. I am not an expert on this but this is just an advice.....i have told you what will happen if u flash coj5 build now its up to you to decide. I would suggest you wait and wait if you are lucky to get a response from an expert and do what they say .......if not then give this a try!
**EDIT** another idea....First flash a custom recovery such as TWRP....see if it lets you boot into recovery and if it does then perform all sorts of formats.....and factory resets in there see if it works....if its still rebooting after format then flash the coj5 build of 5.1.1....note that you "MUST" format it with TWRP first and then check if its working because once you have coj5...it might not let you flash custom recoveries.

You can flash TWRP through ODIN while on COJ5 bootloader. It's locked but you still can flash recoveries and kernel and 5.1.1 ROMS
I am very interested in this thread. I have the EXACT same problem as you have after installing SimplRom, which was a ROM prior to COJ5. It could indeed be that our bootloaders are locked now?
I am using the N910F and just like you, installing any ROM/Custom Recovery/Bootloader/Kernel doesn't help. Perhaps installing a COJ5 ROM might help. I will give that a try, but I've recently used Kies to install the latest official firmware, but it didn't fix the issue.
I will report back here and we'll work on this together to make our phones work again!

Thanks to you and dork97 for the ideas. First some notes:
- I have never flashed a custom ROM, nor ROOTed this Note 4. The recent upgrade to 5.1.1 was official.
the first upgrade to 5.0.1 was automatic and after that I turned off automatic upgrades and upgraded to 5.1.1. manually. So I dont think it was an upgrade that caused it and it certainly was NOT a custom ROM or ROOT. I was doing nothing at all when the boot loop started.
- I'm not sure what ROM I had, but when I went looking for the available Portugal unlocked ROM, which _should_ be what I had, the latest were CJ03 (3, not 5) and before that CH03, CI03. Presumably I had one of those (my last update was October, so probably CH03).
I have tried all 3 of these, but the symptoms are the same.
I'm tempted to try the TWRP option - but would like some more details on what is and what it does, or what problem I might have that it would fix.
However I am probably still in time for a warranty repair - especially since I didnt actually do anything for this to happen. I would like to avoid losing that chance.
If I do take it in for warranty, I'd like to wipe the memory first though. How can I do that?
Finally can anyone actually tell me if the NAND ERASE is likely to help? How does flashing TWRP compare?
I get the feeling in fact, that I have a hardware problem. Especially given there were not software system changes around the time it happened, and given that it loops while trying to boot into recovery mode. In fact the only mode that doesnt constantly cycle is download mode. (Even holding the power button in dl mode does nothing which makes me suspect that, but pulling the battery out and replacing it leaves it off until I press the power button so perhaps not)
Thanks for the replies so far. Any more ideas, details?

I have the exact same as you. I did install a custom recovery (multiple) and still get the bootloop. From my tries yesterday, I indeed also suspect it may be a hardware issue. Perhaps to do with the battery/charging port. When I have my device unplugged and try to start in recovery/normalboot, it does not have a bootloop but simply turns off (and then doesn't respond until I pull the battery out). I think a NAND erase wouldn't do anything as I've personally tried that already.
Have you prior (upto a week) before you got the issues had your phone in a moist environment (bathroom while showering for example). I got my problems a week after I accidentally left my phone in the bathroom and installed custom ROM (which was done earlier and had no issues).
I've read online that it may have caused oxidation on the inside and may need some cleaning/drying with alcohol.
I still hold hope that we just have a software issue as download mode is working fine (apart from the Power off not working unless we pull out the battery).
Anybody have any experience with oxidation on their phone? Perhaps have had a similar bootloop due to hardware failure?

Thanks to you and dork97 for the ideas. First some notes:
- I have never flashed a custom ROM, nor ROOTed this Note 4. The recent upgrade to 5.1.1 was official.
the first upgrade to 5.0.1 was automatic and after that I turned off automatic upgrades and upgraded to 5.1.1. manually. So I dont think it was an upgrade that caused it and it certainly was NOT a custom ROM or ROOT. I was doing nothing at all when the boot loop started.
- I'm not sure what ROM I had, but when I went looking for the available Portugal unlocked ROM, which _should_ be what I had, the latest were CJ03 (3, not 5) and before that CH03, CI03. Presumably I had one of those (my last update was October, so probably CH03).
I have tried all 3 of these, but the symptoms are the same.
I'm tempted to try the TWRP option - but would like some more details on what is and what it does, or what problem I might have that it would fix.
However I am probably still in time for a warranty repair - especially since I didnt actually do anything for this to happen. I would like to avoid losing that chance.
If I do take it in for warranty, I'd like to wipe the memory first though. How can I do that?
Finally can anyone actually tell me if the NAND ERASE is likely to help? How does flashing TWRP compare?
I get the feeling in fact, that I have a hardware problem. Especially given there were not software system changes around the time it happened, and given that it loops while trying to boot into recovery mode. In fact the only mode that doesnt constantly cycle is download mode. (Even holding the power button in dl mode does nothing which makes me suspect that, but pulling the battery out and replacing it leaves it off until I press the power button so perhaps not)
Thanks for the replies so far. Any more ideas, details?

Well if you still have warranty then don't try anything on your own and go for the warranty repairs.

thanks. How can I wipe personal data without voiding the warranty, using odin or kies? Given I canNOT get it into recovery mode, only download mode.

Since you can get into download mode I'd flash firmware through ODIN again after verifying it's correct.
I'm seeing off the sammobile site for the 910F not all are the COJ5 locked bootloader.
Since you did update in Oct you may be on the COJ3. I'd try one of those and see if it works.
If it doesn't work and stops on the sboot.bin file then you have the COJ5

i am sorry i don't know any way to remove personal data other than doing it via recovery. There is an option of "nand erase" in odin it is used while flashing firmware and it wipes everything on the phone but i have never used it (and also don't know whether it can help you or not) ... Senior members kindly help us with this.
Any update to your situation?
very interested as I am in the same situation as you are. Download mode works, recovery+normal boot not. No matter what ROMs/recoveries I install
Same issue I think
I am also in the same situation, although I can enter the recovery mode - home power and volume up - I have tried the wipe cache and then factory wipe to no avail - I have also entered download mode and flashed the stock recovery and even though Odin says pass, it is still in a boot loop. Also when I go to the download screen it has a line saying knox warranty void 0x1(4) does this mean I have voided the warranty even though I only used Odin to flash stock recovery?
Did anyone found a solution
Did anyone ever found a solution to this problem I'm having the exact same issue on a note 4 smn910a
I have a slightly different issue with my Note 4 SM-N910G, wherein am not able to start the phone at all, it is completely dead, if i put the cell phone on charge then also there is no LED on the top but if i connect the device to the PC it does make the connected sound on the PC but Odin is still not able to recognize the device neither kies. I tried draining the power by removing the battery, connected the device to PC without battery and then inserting it but the same problem. Please suggest me any resolution for this dead body am carrying from past few weeks.
hi Op,
did you find any solution for this issue?
Hello all. This is advice to use as a very last resort if you are experiencing the recovery bootloop issue AND you don't have the emmc failure bug. I had the recovery reboot, sudden shutdown with no warning, etc. issue for the past two weeks. I tried everything on Google and Youtube to fix my problem with no success. I flashed multiple stock ROMS and recovery tars (stock and TWRP) via ODIN, but nothing worked. Oddly enough, I never received the emmc error that I have read about. Also, in the few times that my phone booted normally, I even loaded the Wakelock Power Manager app, set it to partial wakelock and my phone STILL continued to bootloop. As a last resort, I bought a new battery, but the reboot problems continued in Android 4.4.4 Kitkat, 6.0 Marshmallow, 7.1 Nougat and 8.1 Oreo ROMS. Well, here is what finally helped me to get my phone back operational. I had a backup ROM from a previous install and a TWRP flashable version of the same ROM on my SD card (in case the phone did not stay on for the full restore). I put the phone into a ziplock bag into a freezer for about 20 min. (thankfully this time TWRP stayed on long enough for me to do the following):
1) copy all the files I wanted to save from internal storage to a computer.
2) performed a full wipe (Dalvic, Cache, System, etc. Like when flashing a ROM, but this time also internal storage. Note: Please do not wipe both internal and SD card, as you may have a difficult time trying to load the ROM file back on the sd card (assuming you don't have a card reader).
3) After wiping, I was able to restore my stock ROM backup (or you can just flash the stock ROM).
I can't be 100% sure, but I think my wiping internal and then flashing the stock ROM finally did the trick. Since this morning, the phone has been pretty much back to as it was before. In either case, I'm sharing this with the hope that it helps someone else.

Failed Root -- Bricked Bootloop SM-G930A

I'm completely at a loss at this point.
I attempted to root my Samsung S7 (AT&T) with Odin, and received an error. This is my first time ever rooting a phone, and I am generally oblivious to this kind of stuff. I disconnected the phone, and it began bootloop. I loaded it into download mode, and attempted to reset to stock. However, I have had endless issues trying to flash the stock firmware to my phone. At one point I unplugged the device once again, and I received the "use Emergency Restore" error screen. I tried to restore with Smart Switch, but I was not able to access my S/N (box is nowhere to be found, managed to find a S/N on Samsung's website since I registered it but Smart Switch wouldn't take it). So, I figured trying to restore with Odin was my last option. I have tried at least 3 different Odin versions, both modified and not, and not a single one of them has worked. I've received Complete(write) errors, Model Dispatch Fail errors, and Re-Partition errors. I've tried about 3 different firmware files as well, and while I think the one I have right now is most recent, none of them seem to be working. I thought maybe an issue I was encountering was that USB debugging or whatever it's called was disabled, but I have no way of telling because I cannot boot my phone.
I was fiddling around with all of this from 11pm to 6am last night, and picked it back up as soon as I woke up. I've been freaking out about this for hours.
I feel like I'm running in circles here. I don't understand what I'm doing wrong. I'm recovery bootlooped as well. The only thing I can boot is download mode.
I wasn't very cautious with this process, and I am completely unfamiliar with most lingo on these forums and the whole process in general. I really regret trying to do this. So -- is there anything else I can try to do to fix it? Or is my phone bricked for good??? I'm endlessly frustrated and have honestly felt like crying a few times over this. I shouldn't have messed with something I know nothing about. :crying:
I thank you for your patience in dealing with me as a beginner + appreciate any help you're able to give.
Cheers.

If you can at least get into download mode, then simply flash it with the latest STOCK firmware for your particular model.
That will bring it back to life, and you can attempt rooting it again, if you dare

Did you finally recover your phone? I'm in the same problem here since yesterday and feel your frustration right now. My phone is a Samsung S7 model SM-G930A from AT&T.
I found this thread https://forum.xda-developers.com/ve...-to-notes-root-install-xposed-unroot-t3411039 and I following the "Return to stock part", now downloading the firmware. Hope it helps.
I'm stucked in the blue screen "An error ocurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software". Of course I try the Smart Switch but says that my model is not supported!
How can you recovered the download mode? I press the on/off button for some seconds and the screen turn of, but it turn on again with the freaking blue screen "An error ocurred while updating the device software. ...". I tried all the possible button combinations.
Thanks and good luck.
Stock firmware
Make sure when you go into download mode and flash that plugging the phone in is the LAST thing you do. I.e. plug phone in only after it is in download mode and only after you open Odin. Secondly, make sure you flash the STOCK firmware, as in Android Marshmallow v6.0.1 . Additonally, make sure that the re-partition option is NOT ticked, and also you might want to try turning off auto-reboot, and just hold the power button after unplugging once the status bar is all the way full and Odin says complete. Also, you need to make absolutely sure that you're getting the firmware for your exact device. I.e. SM-G930A stock firmware is NOT compatible with SM-G930F models. You could also try reinstalling the Samsung drivers. I just flashed to stock firmware then updated back to Nougat yesterday, mostly without a hitch by following these guidelines. There is a download page on rootmygalaxy with all the stock firmwares, that's what I used (I'd link but I just registered here). There is a very helpful guide on droidviews about how to update to Nougat 7.0 once you have finished flashing the stock firmware.
If I were you, I would just avoid rooting altogether. Rooting for me caused very bad performance and battery life, and it wasn't really worth the trouble. Sure, getting in-app-purchases for free was nice but I never tried flashing a custom ROM or anything because most of the stories I read involved soft bricks, bootloops, etc.
Hopefully not having USB Debugging and OEM unlock ticked doesn't brick your phone, I'm doubtful that it will. For the poster above me, make sure your phone is all the way off, the download mode button combo is vol. down+power+home all at the same time, and hold them. A screen should pop up saying press vol. up to continue. If you're still having problems, I regret to say that I am also relatively new to this and I am not all that knowledgeable.
I just made a post about my unrooting process, hopefully it helps!

Sm-g955f bricked - flashing stock firmware only made it worse

Hi All,
So, I have spent 2 days trying to get my Galaxy s8+ back to normal. However, I seem to only have made it worse. It all happened when I decided to change the /data partition from ext4 to another format and then back again to get the /data partition to mount in TWRP after flashing Pascal Rom. However when I rebooted, nothing worked, no boot up screen, no recovery, no life, but all I could get was download mode. It then must of froze up after another restart and I couldn't get anything for 12 hours or so.
The next step I tried once i got download mode again was to flash stock firmware for the G955F, I can't remember the version of this firmware, but I still had nothing change. So then i flashed the latest firmware from SamFirm's downloading client, which was G955FXXU2CRF7 - Australian Optus Branded Firmware (OPS). I was able to get as far as the "hello start screen" and then my phone restarted, it then tried to upgrade my system again, then started "erasing" and then it rebooted and I still had the same issue, nothing but download mode and still no recovery, it still wouldn't turn on. So I flashed the latest International/Unbranded Australian firmware (XSA) - G955FXXU3CRGH, still the same result. I now can't go back to the OPS version of firmware because I get the Check error with the bootloader (since it's a more recent version), so I can't go backwards. I also can only flash "Official Binaries" now. Oh and to make things worse, I read that Odin Option "Nand Erase" just erased user data, so I thought I might as well try it, and as a result, I now can't flash even the (XSA) firmware because of ODIN failing and I now have an "An Error has Occurred while updating the device software. Use the emergency recovery function in the smart switch PC Software.". I am a bloody idiot :good: . Oh, I have tried multiple versions of Both Samsung Kies & Smart Switch (Which both had the option for "recovery & initialisation"), however, I get a message that my device is unsupported after adding in my device model and S/N. I tried a PIT file and then found out it's now included in all the latest firmware img files.. so yeah lol. Fun times. Soooo I feel like I am out of Options, nothing I do is working. The worst of all this is my wife is not happy haha which means after years of tinkering with android phones (flashing custom ROMS, Kernels, Root Solutions, e.c.t ), this may be the end of the road for me if I can't fix this phone. I really hope this thread isn't true too : https://forum.xda-developers.com/galaxy-s8+/help/sm-g955fd-access-download-mode-t3748228
So Please, someone help me out if it is at all fixable even if it requires opening the phone up lol.
The stats i have on download mode are the following:
RMM State as Prenormal
OEM Lock: OFF
FRP Lock: OFF
CARRIER_ID: OPS (which is super weird because it only accepts XSA to be flashed :S )
Secure download: Enabled
System Status: Custom
Warranty Void: 1
Current Binary: Samsun Official
If you need more, just let me know.
Ok, quick update: I have got rid of the error that I mentioned. I managed to flash XSA firmware again, it went to the blue Andriod is updating the system screen, then started "erasing" then rebooted and nothing again, still only download mode available. Nothing happens when I try to turn it on or try recovery mode.
This firmware you mentioned XSA - G955FXXU3CRGH i would double check. As far as I know Australia doesn't have a version 3 bootloader yet whether unbranded.telstra or Optus.
Quick Update: Maybe Fixed now!
Even though no one has replied yet, as it's only been an hour or so. I just wanted to let anyone else know who is experiencing a similar issue in the future on how to possibly fix it.
This was a real nightmare, however quick disclaimer, I am not responsible for any damage incurred to your device/property by following my instructions.
So the way I have fixed it, is I flashed the AP file only (from the firmware zip i had downloaded from SamFirm) with "Auto Reboot" Off. When ODIN finished, I held the Vol Down + power button, to reset it. It gave me a blue "No Command" Screen, I then waited and it then went black and the recovery screen appeared. I cleared the cache, rebooted to bootloader, which it didn't turn back on, so I left it because I thought it was the same thing. Came back 10 mins later and turned it on (or hard restarted, can't remember) and it worked. It booted!
I did soon learn it looks like it was having a charging problem because it had no charge and kept telling me there was water in the port (even though it was dry), I restarted it again after putting it on a wireless charging pad and it is seeming fine so far with the USB charger. So big note to anyone in the future, that it could be possibly bugging out with charging as well if you can't get it back on. I did have the device tell me here and there the last two days that there was water in the port when it was off. So kinda weird.
I know this all sounds a little hocus pocus, superstitious almost, but hey, my phone is working, so maybe replicating my actions may just help lol. :cyclops:

Oh right, well, I did hear that SamFirm is not supported anymore, as that's where that firmware came from. Maybe it's dishing out incorrect firmware now? Possible the structure of where ever it is getting its firmware from (pretty sure it's pulled from samsung) has possibly been altered?
Just for reference I use www.updato.com for downloading firmware it is usually up to date. No reference to the firmware you mentioned (not for Australia anyway)
The screenshot I took: Imgur link:

Interesting I'll keep a lookout for it. Still on nougat 7.0 (XSA) no plans to upgrade yet until some issues are fully resolved ( out of beta stage that is ).

Yeah, it's seeming to work now, but my fast charge isn't working. However, my other oreo ROM didn't work with fast charge either. So i am unsure if it is my phone or an orio bug :/ lol
Well at least you got it working and not using as a door stop
that was really sad story man.....
