So my assumption is I forgot to turn on developer unlock. All I get now is vertical lines when I turn it on. It WAS showing a samsung logo before but now its all messed up. When I go into download mode I can vaguely see the big arrow but I cant do anything. Is it ded?
Edit: Got it in download even tho I cant see anything.
Flashing a stock FW isn't fixing this. All I did was flash a twrp recovery, I didn't think it be this hard to revert.
I got custom OS on it and working twrp and the screen works sometimes now. Just gonna return it. Has to be a physical defect.
Got a new one, got twrp on it and crDroid and its all good.
dark background with red stripes?
what twrp version have you flash?
use last version 3.2.3-4 for oreo

I left my phone charging overnight as I have done many times with no issue. When I woke up I pressed the home button and the only thing that shows was my wallpaper. Wouldn't show anything else. I then did a battery pull. It now gets stuck at the note 4 powered by android screen. A little history in case it helps. This is an unlocked at&t model that I am using on t-mobile. It's not rooted or anything. A few weeks ago I downloaded the recent 5.0.1 small update. In the past week a notification keeps appearing and disappearing from the menu. It was dm software download or something which would disappear if I clicked it.
So it's stuck on the boot screen today. I booted in to the recovery screen. It starts by saying "installing system update" with the little android. Then it goes to recovery menu. At the bottom it says "dm-verity verification failed". I tried to wipe cache and reboot but it still gets stuck at the boot screen. Another small detail is after turning phone off if I plug it in the charger it stays at the grey lighting screen and does not show any battery percentage.
I don't know what to do. I really need my phone today as I am traveling. I hope someone can please help me. Thank you.
In the case u tried recovery now u should flash ur stock rom.
How do I flash the stock rom? Should I do that before trying a factory wipe/reset? I haven't tried that because I really dont want to erase everything unless I have to.
When u do the flashing everything in your device will be lost. So if u do the flashing then u just need to backup all your data.

First u have to download your stock rom
Anyone else have any ideas? I really have no clue how to flash the stock rom. Is there a guide I can follow? Thanks
Just google your device name flashing

I would suggest you start download stock as already mentioned by previous mentor
Than try to make a factory reset from recovery while stock is downloading. In case factory reset all your apps and settings will be gone but your data stay untouched.
If positive with factory reset no need to flash stock anymore
I just tried doing factory reset/date wipe and it's still getting stuck at the boot screen. I guess I need help now to flash the stock rom. Again I have never done this so I appreciate it if someone has or could find a simple guide for me. I just don't want to download the wrong file and mess phone up even more. It's an at&t model SM-N910A. Thanks again
How long did you wait after wiping? For lollipop its normal after wiping to see nothing but Samsung boot up logo up to 20 minutes
In response to above. It did the date wipe/reset which did it in like 5 seconds. I rebooted and left it on the boot screen for about 3 minutes. I should wait longer then? Another thing I was going through kies to see if anything could help. I ended starting a firmware upgrade. I entered my model # and S/N#. It then asked me to go to recovery and made it to a screen with an android, "downloading do not turn off target". That's loading now and i'll see what happens. I also checked on google and it looks like there is a program called odin that will flash the stock rom. I need to find that program and also find the stock rom file to download?
Yep. Google for Odin, download and extract it on your PC. You'll need to download a stock firmware from Sammobile for your device. It will be as Archiv so extract it. In Odin click on AP and choose extracted file.
Another update. The firmware upgrade through kies went through fine. It booted up like normal afterwards. I didn't know it would happen but I am back to kit kat 4.4.4 as well. I wasn't too thrilled with lollipop so maybe that isn't a bad thing.
Hey guys. About a week or three ago I saw nightlies started rolling out for the D802, and decided to try the third nightly that has been released. While flashing itself went fine, I'm having trouble with getting the ROM to boot. After the LG logo the phone enters a blank screen, and won't do anything at all. I can barely notice that the backlight stays on, and I noticed that during this bootloop or whatever this is, Windows Explorer spams over and over I need to format the disk before I can use it when the phone's plugged in. I've read from someone that I should flash the ROM and google apps simultaneously, thus I've added them to a flashing queue and wiped the Davik cache after the flashing.
At first I thought it might've been my recovery being out of date, since I was running TWRP v2.6.x.x before, so I flashed the most recent version I could find which was v.2.8.3.73.
Doing this however made no difference whatsoever, so I gave up at this point and decided to wait for a week or two for the developer to fix a potential issue on the ROMs end.
Now it's fast forward to two weeks later where I'm typing this post after trying to flash the most recent version of cm13 which was available for my phone (the D802).
The problem is I'm starting to run out of ideas to do, so I'm hoping somebody can hold my hand regarding this issue. I really like to try Marshmallow and it's really irritating it doesn't work.
Thanks in advance guys!
i yhink you need to install boostacks when you install boostacks for your varian. dont reboot into system, just go back to main menu. then reboot into recovery from recovery. then copy the rom. flash and gapps ...

Thank you!
I was having the same trouble with lineage OS 14.1 on my D802.
I always got a black screen after the logo of LG appeared.
luckily I could get to TWRP and push the alternative bootstack via "adb push (filelocation) /sdcard/"
Thanks a lot!

Newbie here - I'm having the same problem with my D800 after Lineage OS 14 flash via TWRP. Where do I get an 'alternative bootstack'?
Get bootstack from here!

I'm usually fairly good at troubleshooting my own stuff but this really has me stuck in the same place for a few hours now.
So basically Flipboard has been nagging me(well play store is, not the app itself but anyway) so I said to myself why don't I uninstall it since I've never used it and don't plan to, and besides I hate to have pointless apps installed. So I open TitaniumBackup and I see it is installed as a system app, I thought what's the worst that can happen? so I do uninstall it and a minute later my phone shuts off. I try to turn it on and it doesn't go past the Samsung Galaxy Note 4 flash screen, it either reboots or stays like that.
I try to go into recovery to restore a backup and I can't, it is stuck at Recovery Booting and again it either stays like that or reboots and does it again and again and again.
Now, I haven't made any changes or installs on my phone for weeks now, so this is either because I unistalled Flipboard(I know I shouldn't have risked it since it was a system app but I really could not see it going this way) or the hardware is on it's way out(don't see what else could it be).
I figured I should flash a stock rom with odin, I can get into download mode, and reinstall everything from scratch.
I took a stock image from xda and flashed it and it does exactly the same thing.
Right now I'm downloading another stock image from sammobile for my country/provider to see if this will change anything.
What else can I try? I'm completely stuck and I really don't want to send the phone back like this, I doubt amazon is gonna be happy about it.
Specs:
N910F
Emotion Revolution 12.1 Rom
POK1 BL&CP
TWRP 2.8.7.0
Really sorry for the double-post. I'm quite desperate and need my phone for work.
Since last post I've tried flashing N910FXXU1COH4_N910FH3G1COH3_H3G.zip through Odin from SamMobile and it did the same thing with rebooting constantly.
Then I've installed Kies and went to Tools -> Firmware Upgrade and Initialisation and gave it the model and S/N and it downloaded something and everything went all right, the phone reboots and I'm back in the same circle, it just shows me the splash screen(in some video's I've seen that after this procedure they get the splash screen and then the android bot with a progress bar, I don't get that, I only get the splash screen and reboot) and reboots.
I thought this was a last resort thing? Is the phone completely dead or is there something I can try?
Again sorry for the double-post.
Update: still no progress so I've contacted Amazon and they said to send it back so hopefully this works out in the end, no matter how annoying the waiting time will be, if you do have any suggestions on what I should try please let me know as I haven't posted the phone yet.
Got myself in a right mess here -
I'm on the 2nd to latest version of N (NPD56N) and cannot for the life of me get any recovery to work. I've just messed about with the decryption problem, and have flashed a no-force encryption boot.img. The phone boots and works fine, but I can't get any recovery to flash, despite fastboot saying it's worked fine. I did have TWRP installed for a bit, but it only worked once and then I got the red explanation mark of death and depression again. Note, the power+vol up does nothing as it usually does - This is the main issue!
I understand i'll need a new boot.img once upgarded to NPD90G, but that's not the issue right now.
I'm trying to go back to stock everything (I mean, I only rooted to get the damn new Nexus launcher to work properly, which I can't even install)
Basically, i'm trying to get on the latest version of N with root access and a stock recovery if possible.
SOMEONE SAVE ME PLS
Thanks
Edit - Finally fixed. Wiped everything I could and used Skipsofts tool to install 6.0.1 and success. No idea what caused it.
Resolved.
Okay, so usually I'm quite savvy when it comes to technology, but this one's stumping me.
Yesterday afternoon, I turned my phone off to go into work. It was working quite normally before then. When I get on break, however, I find that my phone won't get past the main logo. I figure that my phone needs a reflash, so today I went to reflash the xXx rom. Still no luck. I tried flashing stock OOS Beta 3, but then my phone went into a recovery bootloop. I tried flashing those two roms several times, but now my phone just stays in a recovery bootloop.
I'm pretty sure this isn't software-related, but I want to be wrong. That's why I'm posting here first, just in case it isn't.
I didn't do anything for it to go into a bootloop, I just turned it off after a normal day, and now it won't turn back on.
If you are decrypted you need to flash the no verify zip for OOS to boot up. With xXx anything from the version of Magisk used to one of the mods you chose in the aroma installer can cause problems. Your best bet is to boot into TWRP, format the data on your phone using the option in the wipe tab, connect your phone to a computer--it will be recognized like an external harddrive--copy and paste a full ROM zip for stock OOS Oreo onto your phone and then flash it with TWRP. Also make sure you are using one of the recommended versions of TWRP for OOS Oreo. The best version right now is the one from Codeworks. Good luck.
