After Logo black screen, no root, stock rom 4.4.2 - G2 Q&A, Help & Troubleshooting

Hallo,
i hope someone can help me here.
After a low battery my phone doesnt turn on any more. After some research i thought it might by the "death battery problem". So i but the phone on Laptop Charge port for 6 hours and i got it booted in to system.
But only for some seconds and it turned of again. So i decided to buy a new battery. Installed it and tried to boot. Sometimes it bootet in to System, sometime just got Blackscreen. I tried hard reset in it showed some errors. That was some days ago. Now it boots and everytime blackscreen. I tried also longer presses like 10 secs and 60secs. I tried fast press for hard reset with boot logo. I have no detection on Windows. I never rooted the phone and it has still stock rom. Must be the latest kitkat 4.4.2 i guess. I checked every cable. No charge led or logo.

Hey dude check out my video https://youtu.be/rpmbk9RFE_U there is step by step instruction how to reflash your rom... Just watch im here for any questions.

Confused....G1 stuck in boot cycle wont wipe

Looking for some help, my phone broke so a friend gave me his old g1 that has been rooted. when i power on the phone i get stuck in the boot cyctle of the g1 logo and then off and the repete.
i cant get the g1 to do a restore, the only change i can get is when i hold the back key when i turn it on. i get the rainbow scree and "serial 0" cant get into fast boot....
if possible i would like to get this device usable and even better with a cstm rom and froyo or what ever is reccommended.
any help would be amazing.

[Q] Sudden shutdown, phone won't boot.

I had just finished flashing and configuring crash rom v19, when my phone suddenly powered off.
Now it's not the first time I flash a new rom to my note 3 by any means, but this is a first.
Now my phone won't power on if not plugged in, and even then it powers on for less than a second, long enough to see the battery charging picture or the note 3 logo.
Recovery won't boot, but download mode works flawlessly, I pulled out odin3 with the stock ROM for my sm-n9005, checked the regin was right and everything, and after flashing using odin all I got was my phone rebooting over and over again trying to access recovery, then it booted no problem to the samsung logo, played the tune and even showed me my lockscreen for a second, and it's back to rebooting itself every 3 seconds.
Anybody have any idea what I'm facing here?
Edit: First thing tomorrow morning I'm going to take it to a store to try a new battery
@E-Chan42.
You can try this out.
I am not sure will this fix your problem.
First, charge your phone for 3 hours. Second, hard reset your phone then flash Stock firmware using ODIN.

I've had my phone plugged in for a short while, but since it keeps vibrating, showing an empty battery picture turning off, vibrating and so on every second I'm not sure charging will actually difference to my issue, still thanks for the input and I'll give it a try.
Ohm....
Then I guess it must be a Battery issue.
Give it a shot. Let's see if that works.
Took it in to my retailer and samsung guy restored the original ROM with Odin just as I did, when it didn't work he sent it off under garantee, thanks for your help! I'll update when I get a word back!

Galaxy Note 4 - No Power , Wont Charge

Hi All,
I've done a fair bit of Googling about this problem and I'm fairly certain my phones (hard) bricked, but I said I'd post just to make sure.
I have a Galaxy Note 4 N910F running a custom rom ( I cant remember which ROM, I think it was like Kyros Final Edition Note 5 Port or something) , I've been running it for a few months with no problem, last night I was uninstalling various apps from my phone, games etc... when my phone froze and turned off, when I turned it back on it was stuck in a bootloop, showing the galaxy note 4 screen vibrating twice and turning off and repeating.
I tried to boot into TWRP but it just froze on the Note 4 logo with "Warranty Bit Recover Set" or something along those lines at the top, when I took the battery out and put it back in, the phone would no longer turn on, nor will it charge, its completely dead.
I somehow managed to get it turned on again after a while, went into download mode and using Odin installed a stock rom, the install went fine however when the phone restarted after the install it said "booting to recovery" and ended up with a dead Android dude and a "no command message" , I got into recovery mode then and cleared the cache. Then I restarted the phone again and the same thing happened.
Now the phone wont turn on again, I've soft reset it, left it plugged in charging for a while and still nothing. Has anyone experienced something similar to my problem before? Any advice/help is much appreciated.
Thanks
Alan

Probably bricked LG G2 running SlimSaber

So basically this rom is awesome but it had only one problem. When I plugged my phone in the charger while it was turned off, it bootlooped until I restarted with the cable off. It was no big deal and nothing bad ever came out of it.
Yesterday my batter ran out while I was asleep and when I woke up it was already turned off. I, absentmindly, tried to turn it on, LG Logo, off again. Did it one more time, nothing happened, realized it's out of battery. Plugged in charger, try to turn it off/on, usual bootloop happens. Say ok and proceed with what I always did, phone gets past LG Logo, goes into SlimLP boot animation and for the first it has just stayed there. No restarts, just endless loading. Longest i Left it on to load was about 45 minutes. Never got back on.
Apart from that, I think that for some reason my recovery got uninstalled somehow, by itself, a few weeks ago. I only noticed this because before, when I wanted to get into recovery, I pressed the usual buttons and it went straight into TWRP. Now the same buttons take me to the "Factory reset screen". I know that everyone says to just go ahead and press power, but I am afraid, since I am not sure if TWRP is still functioning. This happened to me another time on the same phone, and when I confirmed the factory reset, it factory resetted.
My problem here is that I want to get my music and photos. I'm only able to enter that factory reset screen and download mode. Can I "flash" twrp safely from download mode? Should I use Flash Tool 2014 and Normal flash(which says it keeps the data) a stock g2 rom? Can I mount my phone to the computer in download mode to copy my files? I want the most risk-free approach.
Thanks in advance.

Hi, first If you can enter download mode I think you can flash kdz (Kitkat) file to stock using Flash Tool 2014. But I had this problem once and the keep data flashing didn't work (stucked at 50%), I ended up flashed it with other option (erased all data).
2. You can try the "Factory reset" nice and easy.
I think you can't see files on the device unless you enter Twrp.
It's wise to backup your phone on the computer montly or so, thank you.
I went ahead and nuked my download mode using the SRK tools. Then got access to fastboot, through which I booted to twrp and then I could move my files. All's fine, flashed my ROM again and it's going better than ever.

Note N910G very long reboot

I just bought a note 4 N910G .... I installed TWRP and flashed a custom rooted rom marshmallow... I noticed reboots are very very long (whatever types of reboot; normal, recovery or download mode)... I don't know if this happened because i flashed TWRP.
So, i flashed back stock unrooted 6.0 rom but the pb still persists... reboots take like 5 - 10 mins .... it has black screen thinking that it is turned off (pressing power button or any button does not do anything) but if i wait like 5- 10 mins, it actually reboots..
any clue?
