N910H Strange Bootloop problem after screen replacement - Galaxy Note 4 Q&A, Help & Troubleshooting

Hey,
Replaced the screen for my girlfriend (lcd+digitizer+glass), tried to turn it on and nothing.
Tried to reset factory and nothing. Tried to update it from KIES, nothing. Tried odin, nothing.
Stock and custom.
At last i tried HaniBase and it boots, gets to the first screen, where you have to select your language, i can select it and can proceed, but it restarts again, in less then 10 seconds.
Any idea?
Thanks!

Just out of curiosity, did the new screen assembly come with a new Home button built into it?

No home button, its from a different hardware part. I was able to get it working installing cm13

Stuck in startup

My HTC was flashed with TNT. It has 2.21.0001 and 2.21.Olip. I can boot it to boot loader. I can reset it, with switch or pulling the battery. Every time it boots showing the versions, then comes to a WM6 boot screen. This is normal. However it never comes out of this screen. The LEDs flash as if it were working, but the phone is unresponsive.
Is there any way to fix this?
Do I need to reset it in some way? If so, how?
i had a same problem with TNE. after it worked fine for a year.
then i changed the rom to a new 1 and fixed all my problems . just upgraded it in bootloader mode.
Same problem. I installed BlackDiamond2.0. At the begginning everything was ok, then Send button wouldn't work till I press the Start button on the querty keyboard.
Just playing, I tried to overlook with an application that came on the package and then it didn't work any longer. It stays at the BlackDiamond picture.
And I cannot make a hard reset since Send button don't work and cannot connect with Active Sync to flash the rom.
Any idieas?
also could be a bad battery. happened with my brothers phone. acted the same way.
our phones are old now. get a replacement 10 bucks.

Omnia 7 stuck boot screen

Hi,
New phone and new to Windows phone 7. Classic story - the phone has stuck in boot screen, it says only "Samsung Omnia 7" and that's all. I have tried all tips I could find from internet - took the battery out and let it sit, tried to hard reset it -nothing. Actually hard reset button combination seemed not to work - when I turn it on, holding camera and volume down buttons, nothing happens, it shows boot screen and that's all. It do switch to the download mode when I turn it on holding camera and volume up buttons. I tried to reflash it (got the rom files that it came originally), and after restart the situation is the same - boot screen stuck and nothing happens.
I used WP7_downloader version 7.41, Samsung USB drivers v5.02. The weird thing was that older versions of WP7_Downloader did not work - told that flash lock was on. 7.41 seemed to work, it erased and downloaded all areas fine. I don't know if this is normal, but the flashing process itself took about 120 seconds only. I tried alternative ROM (classic I8700XXJK1), the flashing time was slightly different, but nothing changed, after flashing the device restarts and stuck to the boot screen. As I have read the flashing process should took about 10 minutes or so? I waited for about 20 minutes and nothing changed.
Can I switch the device to some debug mode or do something else that could lead me to the reason the device is not booting?
Omnia 7 stuck at boot screen after
I upgraded to Mango last week and i now too am stuck at the "Samsung Omnia 7" boot screen.
The phone seemed to do two updates, the first suceeded no problem. I started the update before going to bed. In the morning it had completed the first and was awaiting my pin code to start the device. All good.
It then prompted about the Mango update. I clicked it and left it for an hour or so. Came back and zune stated it was on the step, "restarting the phone".
The phone was showing "Samsung Omnia 7", i left it for another hour and then came back, no progress.
Nothing i've found on the net up until today has worked for me.
I can enter the format and download modes still.
This is what i've found and tried so far.

(Did a device wipe to factory defaults, and its still stuck at boot screen

(yes this is an older issue but it looked like it was working until it said something about "flash lock").
Next step is a complete ROM reinstall. But i'd really like to find out precisely which ROM i should try and if Mango is the actual culprit. I'd like to reinstall Mango if possible.
My Omnia 7 was bought secondhand.
I am with Telstra NextG carrier.
After mango update mine is behaving strange too. It shuts down itself randomly and it is stucking at omnia 7 screen. After a few try I am able to open it. But I noticed something, it's shutting down much more while it's connecting to web or PC. Can this be related? Because I couldn't find another reason about that.

[Q] Samsung Tab 4 7.0 SM-T230NU won't restart.

I am trying to fix my friends Tab 4 SMT230NU. It powers on just fine, but when I try to restart from the power button. It shuts down then never powers up again. I took the back case off, removed the battery for 10 minutes then plugged it back it and it powers on. As long as I don't choose the restart option it will power on and off just fine. I did a hard reset, clear cache, then reboot thinking that would fix it but being that a reboot is the same as restart I get the same result. It does the system restore. I tried OTA to the newest firmware which fails at the reboot. Tried Kies with the same result. Non-Rooted Tablet. I tried ODIN with the new firmware, which worked on another 230nu tablet, that was stuck in a boot loop, but no luck with the one Im working on for my friend. Screen is cracked could that be the problem? Is the motherboard just jacked? Loosing hair over what I think should be a simple fix.

Not able to start from factory reset again, get's stuck or reboots constantly

hi...
I'm really desperate, my phone is suddenly dying and I have no idea why, I'll tell you from yesterday what has happened:
- I'm playing a stupid game and suddenly the screen goes black. No led, phone doesn't answer any button, nothing. I hold power button, nothing. Remove battery and put again, nothing. After some attempts phone turns on, but just after starting it reboots or stays frozen.
- I decide to change the rom (I had simpl rom), so I do a full wipe and put CM 12. It seems it works, but when I'm in the settings, at the beggining, I don't even have time to put the wifi, it starts rebooting again and/or not responding.
- Desperated, I install via odin the stock firmware from Sam Mobile. It seems it's gonna work, but when the dialog of "Android is upgrading -- Optimazitating app x of XX" it always gets stucked in a number, randomly. I never get to the 230 apps.
- As a last chance, I try Kies to install factory firmware. The same as before happens, but now it's only 17 the number of apps it tries to optimize.
These last 2 times, of course, I enter recovery from time to time (now the default one) and wipe cache partition.
My phone is agonizing, what the f is happening? Does anybody know what could happen?
Please help...

suddenly boot-loop, maybe after phone fell

ok
i've been usign whatsapp and suddenly my phone went into bootloop,
tried to enter fastboot, recovery
but he keeps on boot-looping after 2-3 sec of showing the fastboot-recovery icon.
i tried disconnecting the phone-battery-motherboard-etc, but he keeps going boot-loop, showing the first load screen, black screen, and so on and forth
any suggestions? never occured to me before , only after unsuccessful flashing, but like this? this is really weird.
i have a custom rom yes, but with it for a few months already , 0 problems.
p.s my phone fell on the floor few days ago, but had no problem since whatsoever
any clues on how to solve this?
i can't even get to flash via fastboot/recovery because it restarts when im there..
what could be the problem? the only thing pops into my head is that the restart key is pressed all the time, but is it possible?
I had the same problem, crazy thing. I couldn't even enter orange fox, got to the loading screen and got another reboot. I pressed power button fast many times and then worked. The power button seemed to be ok. The only thing that i had recently changed was the EAS version of the predator kernel. It may not make sense but i went back to HMP and now it's fine.
well! it worked lol
what is HMP? a kernel?
A type of kernel, the common one. Now i know that was not the reason!
Hello
I have the same problem as you and if someone has a solution, I will be very grateful !
I can use my phone but if I push to the power Button, it bootloop.
