Issue with Samsung Note 8 SM-950F - General Questions and Answers

Hi all! I have exhausted every avenue I can think of, with now hitting a roadblock attempting to repartition the device.
I took this phone to get its physical structure repaired as well as the screen. It took them 6 hours. When I got the phone back they said the "software crashed" and that they attempted firmware flashes to no avail.
The phone is in a constant Boot Loop. It will sit on the Samsung splash screen for a minute, go to a blue screen which tells me it is installing a system update, then an Android figure comes up saying Error. It does this over and over again. I hit the power and volume up key to quickly look at the commands it was throwing out and saw it was unable to access certain directories which I assume is the reason for the failure.
So I reflashed this phone with my relevant firmware using Odin. No firmware or combination of files and methods has brought this phone back.
I was hoping for some help with this project. I want to resurrect this phone, it's a great phone. I would love the satisfaction of doing it myself than at a store.

Sometimes after flashing via Odin, it is necessary to boot into stock recovery and factory reset then wipe cache partition then reboot. This doesn't always solve bootloop after flashing via Odin but it is a common solution.

I don't understand how to get into recovery mode. The phone, when the charger plugs in, attempts to boot all the time.
I know the Recovery mode key combo but I have no idea to power off this phone. I've let the battery run.

[Q] Unable to factory reset

Yesterday my phone started acting up. All running process crashed and not many was able to start. I had to constantly click "force close". I think this started after I installed the Google+ app, but not sure.
I have tried uninstalling all unnecessary apps, without luck. I then tried wiping to factory settings by using the Android menu, but without any changing. I then tried by holding vol+ and power, going in to recovery and wiping both to factory and app cache. This doesn't change anything either. By googling I can see some suggests to hold vol- and power, to get to a another wiping-functionality but this just boots my Nexus S to normal state - no menu appears.
Has anybody an idea of what I can do?
Edit: more info; if I click "Report" and investigate the message sent to Google, I see that error has something to do with SQLite-relatet classes. Which makes some sense, alot of my changes are reset each time the phone is rebooted. For instance did I miss a call a couple of hours before the phone went crazy - this is shown at each boot in the notification area eventhough I clear the area and/or goes to missed call section
Factory reset via menu does delete all your "custom" apps, so I'd say it's not one of the existing apps causing problems.
The way you describe function after your factory reset sounds like factory reset didn't work properly.
If you feel safe I'd recommend rather flashing 2.3.4 again using either Odin or the OTA zip from Google (requires open bootloader).
I think you're right that factory reset doesn't do what is expected. Once I click it, the phone reboots and shows the Android guy next to an unwrapping package. This lasts only 2 seconds, then it reboots itself again and goes into normal phone mode (where all the app-crashing starts again).
I have not flashed or rooted my phone before, but I will consider this now since my NS is pretty much a brick. Thank you for your swiftly response.
Edit: Shouldn't I get a menu, when I push and hold vol- button, while turning on the device? Right now it just boot as normal.
Before you use odin....try going into rom manager a reflashing clockwork! Ive had that android dude on my screeen but reflashibg via rom manager always fixed it. Try that

Wow my Nexus has totally shut me out.
I cannot use ClockworkMod unfortunately since I am not able to root my phone. It is not detectable via USA (when I use vol+/pwr and connect USB). I am unable to check the USB Debugging option on the phone. Each time I check it, go to home-screen and back to the menu, it has de-selected it again. Also I noticed when I read the info that is sent to Google for all those app-crashes I get, I see SQLiteException and error in an SQLite.java file. So it seems like some database layer is broken.
I read one could copy the ClockWork.img to my phone and use the standard recovery option to flash the img (I think). But when I go into the recovery menu, the file is gone. When I boot the phone again, it has deleted the .img file - eventhough if I copy it to several different folders, they are all gone :-(.
I feel pretty screwed at the moment. How can I else wipe all data?
I'd recommend to check if your device is correctly identified in windows. Missing USB drivers might cause problems. Get the latest drivers and a guide from here.
If you succeed booting into fastboot properly (vol up and power) you can follow this guide. Get the latest cwm recovery.img here.
Last option would be to boot into download mode (vol up + vol down + power + plugging in usb cable) and use Odin from samfirmware.com
--
All options require correctly working USB drivers.
I managed to unlock the bootloader, by quickly turning on USB-debugging (before any processes started to crash) and install the drivers from this post:
http://forum.xda-developers.com/showpost.php?p=6819751&postcount=4
A reboot later, I got this message:
"System UIDs Inconsistent
UIDs on the system are inconsistent, you need to wipe your data partition or your device will be unstable."
Right below was a button saying "Im feeling lucky" (??)
I installed ClockworkMod using fastboot and tried "Fixing permissions" with no luck. I will try some ROM later on, and hope it will bring my phone back
Normally this error happens when you have a faulty app ruining your system, formating/deleting whole sdcard does usually fix this.

I can safely mount USB-storage and format the whole bunch?
I been sweating over this stupid issue all day now, all I want is a fac-reset :´(
Edit: "format /sdcard" using CWM didn't do anything

See I'm no expert on this whole thing. At this point I'd just flash a whole new system via Odin. Prolly not the smartest or safest option, but that's what I'd do because I don't know better. If that wouldn't fix it either, I'd return the phone on warranty
I was looking at Odin from the start, since nothing else seemed to be working.
So right now I got started on Odin. Followed the .pdf steps and flashed the bootloader at first succesfully. I was asked to remove the battery and re-connect my NS. Began downloading "pda" and "phone", but at around 10% a big fat red "fail" message appeared and now I just see the Google-logo on startup. I still cant flash any roms via fastboot.
Im too tired too right now, been working with this for 14 hours straight. I will look at it tomorrow evening. Thanks for your help rentaric
Weird, you're not the first one who had trouble running Odin using their guide.
Overall it's pretty simple.
Enter download mode. Vol up vol down and power at the same time while plugging in the USB cable. Start Odin, should show a yellow colored box with a port number. Uncheck everything but reset timer and auto reboot. Unzip the correct zip file from samfirmware.com (check if you got i9020 or i9023 and get the universal Odin exe), apply file from the folder accordingly. Bootloader and bootloader. Phone and modem. Pda and pda. Csc can remain empty (will change carrier info in fastboot).
Double check md5 hash to avoid broken files.

Of course I did not go to bed, how should I be able to sleep with a broken phone .
The firmware suggested on samfirmware.com for my phone, was 2.3.3 and some other version (my phone was 2.3.4.2/GRJ22 or something similar, I suspect that might be the cause. Also I unchecked everything, that might also have been of importance). The flash will always fail when everything was downloaded - it then said something about "remote" and "Loke" and then fail. But as I mentioned, I had succesfully flashed boot.img (2.3.3) thus no boot occured now. I googled the correct bootloader, used fastboot and was booting succesfully again.
I began looking more into the sdcard, as error-messages was leading me this way. To compress 4 hours of investigations into a few lines, it seems as my PBA is malfunctioning as other xda-members have experinced. Only solution is sending the phone to Samsung for a PBA replacement. I purchased the phone in Bestbuy USA and the danish Samsung partners are not too joyfull about this - I will contact Samsung and hope they can help me.
I experinced the exact same thing as this poor guy - http://forum.xda-developers.com/showthread.php?t=993403
Every thing you try to do to /sdcard is worthless.
Formatting (USB/using CWM/using adb shell linux commands) says "Succes" but nothing happens.
Copying files says "Succes" but nothing happens. If I boot phone into CWM, mount usb and upload new rom/apk/whatever and try to do a "install update.zip" it fails with some mounting errors.
Im ready to go cry in a corner - I really want this to be fixable via software, but I probably have to realize that this is a hardware issue.
Apparently Samsung doesn't offer worldwide warranty for cellularphones :´(. God it sucks to pay repair-expenses on a 1 month old mobile.

[Q] Boot Loop with no recovery mode

Ok so I'm new to the thread and basically to android tablets, so please forgive my ignorance if it should become prevalent.
I bought a Galaxy Note Pro 12.2 32GB wifi and had it for about one day. I performed a factory restore on the device in which it froze for about 2 hours. (this is probably the stupid part) I turned it off since it was not progressing after a long time and it booted up as a new device. After about 5 minutes of use, it randomly restarted and went into a boot loop. About every 15 or so boot screens, it sometimes boots up, then freezes and goes back into a boot loop. The longest it stayed active without resetting was about 10 minutes. After hours of research, I have done the following
Tried to boot into recovery to no avail. It just continuously pops up the device name screen
I have tried to flash the device with a stock rom in odin 3.9.
It recognizes the device but hangs at the Initialization stage. Sometimes it will give me a fail notice saying that it couldn't open the COM port
I've tried it on another computer, changed usb ports, powered on and off multiple times and nothing changes.
please let me know if i've forgotten anything. Any help will be appreciated.
Also I live in Japan, so if I can fix it myself that would be nice since this device isn't sold here yet, I'm not able to get support from a store. I'd like to avoid waiting a month sending it back to america, replacing it, and getting it sent back. Thanks in advance ^_^
Make sure you have the correct and latest Samsung drivers for your tablet.
If you have an SD card installed, try removing it and see if you can boot up and get it stable.

Wow, you rooted (void warranty) on a day old tablet on a platform that is new to you? I've been rooting Android devices for over 3 years now and have had mine for a week now without root. Don't get me wrong, I have a list of things I want that require root and it will be happening but I figured I should at least run it for a couple weeks to make sure no defects pop up before I void the warranty. Good luck to you!

I've installed drivers a few times. No go.
I'm on it now and the boot loop seems to have stopped, but I still get random restarts. But each time it restarts, it's from factory, so it doesn't save anything I download or any settings such as enabling debugging in the developer settings.

I didn't root, and I haven't voided my warranty. I can still get into download mode and my flash counter is still at 0. I never tried to root, I simply wanted to flash to stock, from stock.
[Edit] I'd also like to mention that Odin has not successfully done anything, Every time I tried to flash it was done with a stock ROM, and everything that has gone wrong has occurred on nothing but the stock ROM
Is it possible that I need a pit file for the device since no version of Odin will get past initialization? ....if so where can I get one for the this model?

I hate to agree since you would have to wait for a while to get the replacement, however the device sounds to be defective. just my two cents as a developer, if you flash anything to the device, root, a new image, or even the factory software, Knox will be tripped and the counter will go from zero to a one. My advice would be to get a replacement for the defective one.
Developers don't need no stinkin' signature!

Huge 3rd.
Device should just plain WORK out of the box. There shouldn't have been a need to flash stock to begin with.
One last suggestion, factory reset from recovery. From complete power off, hold volume up+home button+power and after a few seconds let go until it boots into recovery. From there wipe cache, wipe davlik, and factory restore. Good luck!

Yeah, it's unfortunate, but I have to suck it up and just pay the shipping back to Ameica....then again for it to come back. Just wanted to do everything I could before I had to send it. Thanks for the input though. I guess I learned quite a bit researching processes and terminology which will be helpful in the future. ^-^

Tried many times. The device pretty much gives me the finger by going blank and repeatedly showing the boot up logo when I hold the buttons down.

I voided my warrant after having mine for about an hour (though not new to Android). I did all my random "OCD does it work as I expect/want" tests and it passed, so I rooted. Had it for one week now, and I absolutely love everything about this tablet.

IMO, it will be worth it. This is my fourth tablet, and is the first one I've not had buyer's remorse with. Luckily with the gift credit for Google I was able to get the non-Tegra equivalents of some of my favorite games, too.

After doing research, I think that even if I get a new one, I want to root it. With the problems I've read about for kitkat 4.4.2 I need to know how to fix problems, and start with a fresh install of roms and know how to use custom recovery. I haven't done anything yet, but I was wondering...
Since I'm stuck in a boot loop with no stock recovery, can I flash a custom recovery to fix my issues, flash the stock rom that is on sammobile.com and then root after that? From what I understand this is a soft brick since I can still sometimes access the device. I worked out why I couldn't access the device with adb and now it shows the device as listed. It stays on long enough to where I could flash a recovery before it restarts itself. I'm not trying to do anything stupid, just getting information before I pay the shipping for it back to the states. I've checked the knox counter in download mode, and it is still set to 0, so I haven't voided the warranty yet.
Any input would be greatly appreciated.
It's odd that a new device would not have recovery. I don't want to insult you, but just making sure we covered the basics, volume up+home+power gets you to recovery. The boot logo will flash about three times, make sure you're still pressing all three buttons, then let go after the 3rd flash of the boot logo then you should be in recovery. Volume down+home+power takes you to download mode, this is where you flash roms and recovery. I read in another post about someone not being able to get in recovery after numerous times, it turned out that he was hitting the volume down button instead of volume up. Just to be clear, if you do flash recovery, you will definitely trip knox, at this time there is no way around that.

I understand the skepticism. Yeah, I tried the button combination, usb in, usb out. I can power off the device completely only when it is plugged into power. When I hold the recovery combo from power on, the screen goes black with no flashing of the boot logo, looks as if it wants to go to recovery, and then then the boot logo comes up again, but just continues to the boot animation and continues the boot loop, even if i'm still holding down volume up and home buttons. It will sometimes boot up, then freeze after a couple of seconds, and return to boot loop. On rare occasions it will boot up, but turns me to setup like it's a brand new device. I can access everything for about 10 minutes, and then it will randomly restart and continue to boot loop again after that. I tried update/initialization in kies, but it would restart before the downloading and decompressing of binary could finish. It finished one time and then switch to a downloading screen (although it didn't say odin since you have to manually go there) but the update would freeze at 0 percent no matter how long I left the device there. It's all pretty lame ><

Frozen on Google screen and recovery splash

Unlocked, rooted, TWRP, Cataclysm Final Lollipop (my phone never played nice with any MM ROM I tried, so I just went back to this and have been great ever since)
My phone has been rock stable for months, today I pull it out of my pocket and the screen is black. I turn it back on and it freezes on the Google screen with the unlock logo.
I can get into bootloader via power+voldown, but if I launch recovery it gets past the Google screen but then freezes on the TeamWin page.
Any suggestions, please? Searches intimate power button issues, but given I get no bootloops, I can turn the phone off reliably by holding the power button down, and it freezes at the same point consistently, it's hard for me to think that's the issue in my scenario, too. Thank you!
As an update, I used fastboot to successfully flash the newest version of TWRP, just to be sure, but it still gets stuck in the same spot, as does trying to boot normally.

Thanks for the suggestion. Is there any way to get my personal data off before I do this?
I guess beggars can't be choosers, but I'd hate to lose anything I don't have backed up already if it ends up being another issue after all (the power button, etc.).
A corrupted ROM can prevent a clean, freshly-installed recovery from launching properly?
Thanks again.
Try flashing different version of TWRP? Maybe one of them will allow you to mount the data partition and copy off your data.
While trying to flash the (stock) new system images, I keep getting "remote: flash write failure" and/or "remote: failed to erase partition." This is via a toolkit or manually via fastboot.
The bootloader remains unlocked through all this
It's especially odd, since now I'm getting it on my recovery partition, which I was able to write to earlier today.
A cursory search of this forum suggests I'm SOL unless I replace the whole motherboard, at which point I might as well get a new phone. Do you (all) concur?
Last ditch thought: I went jogging when it went dead--outside chance a connection to the memory on the motherboard got jostled and could be reattached? Or is it fried?
Continued thanks.
The memory is soldered into place but it is possible that something happened during your jog. I also jog with my nexus 5 for 20 to 30 km per week and have done so for the past year without any issues.

KIES says that. (THR) Stock. i downloaded it and flashed with Odin. Then reboot. Then system install update. Then Erasing. Then reboot and No Command! 30 seconds keeps rebooting itself 30 seconds interval Random.
I did factory format, cache clear. then the same problem. i want to install twrp recovery with oden. It says Oem Lock. Not allowed. But i flashed Combinary file. I can get into system and i to developer mode but dosnt seem OEM UNLOCK that ll do enable it.
Ok mate, but if you press Vol- + Bixby + power for couple of seconds, can you access to download mode? If you can, I think you'll have to install the firmware all over again.
Try flashing using latest firmware from sammobile. Use Odin to flash all the files contained in firmware download. Make sure you get latest firmware for your carrier. Google how to flash using Odin. Hope this gets you in the right direction. Good luck finding what u need, do copious amounts of research before attempting any rooting of devices and if all steps aren't clear as day to you then do not attempt it unless you don't mind buying multiple expensive phones to tinker with.
Did OP find a fix to this problem?
I am experiencing a similar issue. Picked my phone up to find had randomly gone into a boot loop. Tried soft reset, cache wipe, factory reset - all successful but the phone would still reboot and be stuck on device model screen. Next I decided to flash the device with stock firmware. The flash passed in Odin, the phone then rebooted, loaded to device model screen, then a screen appeared saying "installing updates" which would make it to 25% then crash. After this the phone keeps booting, shows a screen with a dead android icon and says "no command" or "error". I have tried to flash the device using Oreo and Nougat firmware but have failed every time (although the flash did pass in Odin)
Any help would be greatly appreciated as I would rather not buy a new phone due to a random hardware fault which is out of my control.

Samsung S6 Boot Loop

Hi,
Apologies if this has been asked before, but I've done a relatively thorough search and I can't find a solution to this problem.
I have an S6 (SM-G920F), It was playing up for a few weeks before this, not charging well, and what not, thought it was a cable/hardware issue. Then it stopped working entirely. Initially when it was plugged into the wall it would say it was 91% charged, but if you tried to turn it on it would turn off, and reboot into the charging screen.
I've done quite alot of reading and I've ended up flashing it with Odin (I have a single .md5 file, which i've loaded onto the phone via AP) using the most recent FIrmware UK EE for the SM-G20F. This was successful, however now it only loads the Black screen with white text Samsung S6 powered by android screen and then goes blank and back to the white text screen.
I downloaded an alternative firmware (the one previous version), but this has had the same effect. I've tried to repartition with odin, but this fails.
1.) Is there anyway I can fix this?
2.) If not Is there anyway to remove files whilst in downlod mode?
3.) If I cannot fix it or recover my data, is there anyway to wipe the data securely from my phone so I can sell it for parts?
At present, I can't access recovery mode, only download mode. But whilst Odin communicates with the phone in download mode, I can't seem to access my files from explorer?
1. I would say you'd have to clear cache, immediately after flashing the firmware with Odin, but to do that, you'd have to get to Recovery Mode first...
Why can't you get to it? Does it just start trying to boot nornally? Because if so, it's just a matter of timing it. What I do is... hold power+home+voldown to get to the screen that asks me if I want to get into Download Mode, I press cancel, and immediately start holding power+home+volup until I see the bootsplash screen, and release the power button but keep holding home+volup, and it gets me to Recovery every time, even when I have difficulties such as this.
2. Not that I'm aware of. BUT you could flash TWRP with Odin, and if you then can manage to get to Recovery, you just need to plug your phone into a computer, and your phone will show up in the computer as a device/disk and you can freely remove stuff from it.
If... IF this were to work, I would suggest downloading a stock-based ROM and flashing it. It's far more likely to work properly and bootup without issue than the firmwares you can get, and it's far less much of a headache to do.
3. Nope. There are apps that can wipe data securely (such as Shreddit which does it according to military standards), but it can't be done from Download Mode. There may be some script that could do it in Recovery Mode, but I doubt it.
I mean... technically... you could flash TWRP, go to Recovery, move to your PC all the stuff you want to keep, select the wipe option in TWRP and then transfer randomly generated data from your PC to your phone until it's full - there are many apps that can generate such data. It's not something you could pass off as very very secure, but it should suffice.
I seem to always keep going to trying TWRP - so, you know, give it a shot.

Thanks for your reply! So after flashing it goes straight back into the boot loop. Weirdly if its plugged into my laptop it spend about a second or two on the "Samsung Galaxy S6: Powered by Android" screen before plunging into darkness and shortly after repeating the same message. However if I plug it into the wall it spend over twice as long on that screen before repeating the cycle. It never goes any further.
I've tried your suggestion about perhaps its timing for recovery mode, but even if I go straight from cancelling download mode to trying the power, up and home key it doesn't go to recovery. I've tried a variety of timings both plugged into my laptop and plugged into the wall to no avail. If the phone isn't plugged in, it literally won't do anything whatsoever, won't even hint at turning on.
So Next I tried flashing it with TWRP via Odin and nothings changed, exactly the same bootloop and I still can't get into recovery mode.
I'm starting to think that sadly this phone my be beyond repair! Thanks for your help though, much appreciated.
Hi! I usually run out of my bootloops like this:
try this:
1: go to download mode, and press Power + home + volume —
2: As soon as the screen turns black, continue pressing Power and home, quickly release "volume —" and press "volume +". This will get you into recovery mode.
It always worked for me, so I wish the same for you. Good luck! (And sorry for my bad english)

Hi Vinicius,
Thanks for the suggestion. Unfortunately it didn't work, I even tried flashing it back to a standard ROM from TWRP, but it still didn't do anything, just back to the Samsung logo and the loop continues ever more!
Hi, I have this problem as well.
Originally I had TWRP and root flashed into my phone but for reasons I needed to remove root.
So I followed the Odin route stated here "Mobikin how to remove root from android" (I can't post links but this should be the top result when googling)
However I didn't know if the recovery/boot should have went into AP or BL on the Odin menu and googling didn't give me any answers so I may have tried both....
Right now I tried flashing TWRP and I can't seem to boot into TWRP as well.
I was able to get into recovery mode but clearing data/cache didn't fix it for me.
EDIT: I managed to flash in another stock rom and it boots into the SAMSUNG logo but gets stuck there. I already went into recovery mode to delete data and cache partition but it still doesn't boot.

Same experience. For all those 6 years that I used this device, the wifi was okay until now. It (wifi) is very buggy (turning on and off, and sometimes won't turn on at all) so I restarted the device, then bootloop happens. I flashed the stock rom via odin and clear data and cache. But it is still bootlooping. I think this is the sign that I need to replace my phone IF I couldn't find a fix to this.
