Galaxy S5 Neo Major Issues and Need Help Please

Hey all,
So I purchased a 903F from someone yesterday, its sim unlocked it can make and receive calls etc, but the issue is (and I was aware when I purchased it) that google apps are missing for some reason. So I purchased it cheap and planned to just reflash it with Odin. Upon a little more inspection, it wont connect to Wifi because it says "unable to add wifi connection due to security policy" which ive never seen before. Backup and Reset options are grayed out so you cant reset the phone, a lot of functions seems to cause the "unable to blah blah due to security policy" which ive never seen before and cant see how to disable/change that. Doing a factory reset from recovery does nothing either.. it remains the same as before like its done no kind of wipe at all. Initially I was able to go into the bootloader using the volume down power and home combo as usual but when i attempted to flash using ODIN it failed and it had something like NON FLASH in red writing on the ODIN screen I just noticed in my peripheral. Now I cant get it into download mode at all.. is that possibly due to battery charge level? is there a specific charge level required to go into download mode? SmartSwitch downloaded the firmware and when it attempted to reboot into download mode it just turned the phone back on to its normal boot.. its all a little concerning and hopefully one of you geniuses can figure out whats going on.
Thanks in Advance!

Went to sleep, phone died, now stuck in a bootloop, can't enter recovery and etc.

Stock 7.0 AT&T model, I went to sleep, forgot to plug in phone. It died in the middle of the night, and the phone refuses to boot past the s7 edge splash screen and restarts every 10-15 seconds. It also will not enter recovery mode and says "Recovery booting..." I can make it enter download mode but I have attempted almost everything I have found and I either get a binary issue or it will successfully flash but then nothing will happen and it will continue to be in this bootloop. I actually brought it to a samsung "representative" at Best buy today and she said it wasn't recognizing the phone at first then it did, and she flashed something that she didn't say what it was and then it still didn't work. She then told me to send it in to samsung but since my glass is cracked (2nd day I had it too...) they try to say that i'm at fault. I just want to know how to fix this, I haven't had my phone in 5 days, I don't care about my data cause it's all already backed up online! Any help would be greatly appreciated.

Have you tried using samsung smart switch?

use samsung smart switch emergency software recovery initialization which is in the right up corner in "more". if its gonna be stuck and installing the software then connect your phone to a charger, hold volume down and power button and turn it off, this way the phone should stay turned off. then go to download mode and install s7 edge firmware from sammobile through odin

****, I forgot to mention, yes I have tried smart switch and every time I input the model number and S/N, it just closes out. Based on my research, that means initialisation isn't possible.

you'll need quick hand play
push volume down boton and power at the same time when the phone restars quick push the download mod conmbinaison and flash a stock at&t firmware you can download throught sammobile.com site;*,
edit : download the firmware throught this post: https://forum.xda-developers.com/att-s7-edge/how-to/firmware-att-s7-edge-g935a-official-t3412312
another edit lol: don't forget to unzip downloaded files
tell me if it works

Recently, I have seen many phones with bootloop problems and, at the end, the sim card was the one to blame.
I know it's silly but have you tried booting it without the sim card and micro sd?

Black screen of death after flashing firmware

I have the S7 Edge originally the ATT version but I rooted and flashed the unlocked version firmware. I was trying to unroot the device and restore everything to the factory settings since I am using the trade in program through Samsung and have to send it back in stock. I tried to flash it using Zodin, the Mac version of Odin, but was unable to get it to work because I was not able to get the proper pit file, it always returned with the error that there is a corrupt file. Since I do not have Windows, I could not Flash the firmware using Odin. Out of desperation, I looked online and a website (the article was on Android forums with the title restore stock with flashfire no PC) said that I could use the Android app Flashfire to flash a firmware and return to the factory unrooted settings. I downloaded and inputted the full firmware file for the original AT&T firmware version and checked the boxes to wipe boot, system, internal data, and trusted Zone and also maintain everroot. It seemed to work and was processing with the fast scrolling command text on the black screen but after a few minutes it said there was an error at the very bottom of the screen. Eventually, it restarted but nothing has come up and the screen is black without any light from the LED indicator. I tried to restart it with the power button several times, holding down the power button and the volume down, holding down the home button and the power button, and holding down the power button, volume down, and home button. I left the phone unplugged overnight and plugged it in this morning to see if it would turn on but nothing happens. Any help would be greatly appreciated and I am hoping that I did not brick the phone.

Since Im not sure now if you also tryed to go in download mode again but ussualy you are always able to do that.
If not try to remove battery and put it back in after 10 minuts. And connect it to your laptop and let it charge for a few minuts. Next Hold buttons for dowload mode. Hold em for 5 secconds. Even if still have a blackscreen open samsung kies or switch. One of them has the emergency recovery option. It will detect it then and will say something like you need to repair the software want to continue etc. Lwt it do its thing and make sure you are on the internet. You drink some coffee and give it 30 minuts atleast.
Still not work? Try to put in a spare battery or charge it with another phone. If that not even works. I cant help you.

First of all, I do not have a battery that I can remove. I tried to enter download mode and recovery mode but nothing worked. It will not boot up into any mode.

Just hold the button combination for download mode for 10sec and connect it to a PC with installed smart switch on it. Smart switch should detect your phone, even if the display of the phone stays black.

I tried what you recommended but nothing works still.

I seem to have encountered the same problem, albeit not through exactly the same method. Essentially I managed a full stock firmware flash through ODIN, all the right messages came up and I got a pass from Odin. The phone rebooted and brought up the blue "updating" screen, which very quickly changed to a "removing" screen, at which point the phone froze. When I tried to reboot, the screen went black and now.... nothing. No recovery, no download, no light to indicate that its charging... nothing. My computer doesn't register there is even a device attached.
I've done heaps of flashing and never seen anything like this!
Would greatly appreciate any advice or assistance!

same issue here accept i was just using odin like usual. anyone figure this out yet? the phone was not rooted or anything. i had flashed the g935u firmware and then decided to put it back to stock g935t firmware. then it started doing this.

reflash but this time it check nand erase all

NEVVER EVER CHECK NAND ERASE ALL, dont advise others what you don't know yourself. This is for manufacturer and is not intended for repairing, if you nand erase your phone its just a paper weight then, beyond recoverable. But this issue is caused by wrong partitioning i suppose, but still it must go in download mode, try plugging it in when smartswitch is open in pc while holding home+vol down+power , if it wont detect then i suppose its nand failure due to any reason. And motherboard replacement is required.

I recommended it because I had the same experience of the black screen and blue led that lights up and I flashed more than 50 times without any result and the solution that was given to me and which walked it's this one

If it really did nand erased all, your phone wouldn't even boot, your phone working is a proof it isn't nand erased. What people don't understand is that nand isn't the internal memory, its the non volatile memory holding vital info about functioning of phone just like a bios of computer, so if it is erased you are beyond recoverable damage. Here , i must say i dont know if odin can really nand erase all, because if your phone is working, nand is definitely not erased. And as far as what fixed your issues, there must have been some other reason. But for everyone, leave that option empty just to be safe.

Ofcourse it doesn't effect S7 edge, because it DOESNOT wipes the nand.. so its not working simply..
On older phones it will wipe nand totally and thats a dead brick..
First search what nand is.. its the non volatile memory.. or simply nand chip .. if you delete it.. your phone won't be a phone anymore.. its the non volatile memory that is equal to a bios of a computer.. delete non volatile memory and your phone is completely dead..
Thanks to the latest phones that don't erase non volatile memory and instead selecting nand erase with s7 edge simply deletes userdata before flashing.. which is equal to a normal hard reset ..

I bricked my Samsung Galaxy Tab A p-355

I'm new to rooting phones and stuff. So I tried to root my tab and followed a guide that told me to download Odin v3.11 and enable USB debugging in my tablet and I did. And as soon as I flashed twrp and tried to restart my tablet, the screen went blank. I tried opening it by holding the power its just blank. I tried plugging it in my computer and I think it recognizes the tablet because it makes the sound the computer makes when you plug a usb. But Odin won't recognize it.
Solved the problem.
Anyway as I said I want to root my phone but when going to twrp the screen is just blank. Any suggestions?

Hi all....
I've same problem too.
After try flash with Odin 3.11 and p355 firmware, after process clear, and Odin show "PASS", my phone turn off it self, and never come back again. Display just blank, so I can't go to download mode or recovery mode.
Try push power button for long time, still no respond. But if push many time home, vol down/up tab still shaking, but display just blank.
Any one here can help me how to solve my problem.
Note:
Tab is brand new, but has been lock for Prudential insurance.
Thanks.

Bricked S8s after software update.

Hi. Browsed for ages and always come here for answers.
Here's my problem.
2x S8s. SM-950f.
Updated to most recent software through software update. Both phones were glitchy and crashing and just generally irritating after.
Factory data reset etc. This did not resolve the problems, also led to one of them having issues with FRP (annoying)
Used Odin to try and flash the latest firmware (from sammobile, UK BTU) after flashing both, they reset and powered on. Got stuck at the S8 screen.
Restarted then both were at the "an error occurred during update" screen.
Managed to get back to download screen. Re checked the software and model numbers, even that the bootloader was the correct version etc. All was fine.
Connected to Odin, shows that it is connected, but nothing happens when clicking start.
Now after attempting that, both phones will not power on.
(One will when placed on the wireless charger, but just sticks at S8 screen) and download mode or reset screen can not be accessed. So, not exactly happy. And totally out of ideas
Any suggestions, beyond taking it to a shop to see if anyone can help.

yes .....dont tuch the phones for 24 hours let the battery die ...it will...connect to pc and then try download mode....u may need to press combination for like 1 minute to get to download mode....flash twrp reboot directly into it when odin says successfully .....wipe system data ....dont turn on phone download any custom rom flash and enjoy.....it will trip knox but worth than getting a new board....

Okay, will give that a try.
TWRP?

TWRP install
https://dl.twrp.me/dreamlte/twrp-3.2.3-0-dreamlte.img.tar.html: Download link for twrp SM-G950F (dreamlte)
Just said, wait until your device powers off due battery insufficience. Plug cable and hold at the same moment vol(down)+bixby+power. Then press vol(up) at the warning screen to proceed to odin mode. Let it charging a while like 1 h. Then unplug it and plug it to your pc. In Odin select ap the previous downloaded file. Take your mobile in your hand. With one hand, prepare your fingers to vol(up)+bixby and with the other hand start the flashibg process. Be careful, and take your hand directly from the mouse if you clicked start in odin, and position your one finger to power button, but dont click. If odin start pass, press immidiately the buttons (vol(up)+bixby+power) and let it to start into recovery. If you arrived to recovery, reply to us if not search for help!!!
Good luck

i have the same issue with my s8 but when i boot in download mode the screen goes black but if i press volupe up it connect to odin with black screen you shoud give it a try

Will try that

Okay, downloaded TWRP, can get phone calls nected to Odin but when I extract TWRP it doesn't give a valid file type.
Am I being dumb.
No files appear that Odin will recognise.
Also just shows as "recovery" no .tar or anything

Ignore above. Corrupted download.
Sorted.
Now when flashing TWRP is gets to a fail due to
"Complete (write) fail

Not sure what stage your at and maybe some more useless ideas
1. Trying to flash twrp is kinda of useless if you can't get into your system need oem unlock for that.
2. Have you tried taking out Sim card and SD card and reboot.
3. If you can at least boot try smart switch as it has a emergency recovery option.
4. Trying rebooting in safe mode.

All been attempted
