S10+ keeps restarting, doesn't even go past Samsung logo - Samsung Galaxy S10+ Questions & Answers

As said in the title, it's in a permanent loop of trying to turn on, showing the unsafe bootloader warning, getting to the Samsung logo, and then shutting off and trying again, all on it's own. I tried first by using the usual, but it won't go into bootloader, nor recovery mode. When that failed, I let it keep going at it until the battery was empty, and tried then. It still started the loop, but then it ended because it didn't have enough battery to continue and shut off. After that, I tried connecting it to the computer, but the moment I got the USB in, the phone tried to turn on, and started the loop, again. Even just connecting it to the charger, it tried getting on again.

Can you get into download mode? If so, just use ODIN to reflash the stock firmware. That should fix it.

flash stock firmware via oden...good luck

[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!

[Q] Samsung Galaxy S4 sph-l720t (sprint) stuck in bootloop

I just got this phone alittle over a month ago. Today at work, my phone randomly shut down and started continuously restarting. The phone will vibrate and boot the logo, then turn into a black screen, vibrate again, and restart. I had not modified my device at all. Just downloaded your typical apps like anyone else. I already tried taking out the battery and letting it sit and booting in recovery mode and wiping the cache and restoring to factory settings. I also tried to use odin to flash what i think is my firmware onto the device. I wasn't able to figure out the firmware of the device before I did it so i sort of guessed based on the model. Though all i did for this is download what i thought was the firmware, put it in odin3.4, entered download mode and plugged my device in and let it download. I didnt do any rooting or enable debugging/disable debugging before i used odin. Did I miss a step? Does anyone have any suggestions of something I else do. I am so confused on how this happened to my phone!

Brick Help - Stock Sprint ROM

Hello all,
As fate would have it, the day of me getting my new G5, my G2 went in to a boot loop before I could transfer my data.
I'm desperate to get the data back if possible. Below are the details.
Phone went in to boot loop, then would not turn on. I have tried periodically to turn on the phone, but it will not boot. It will loop at the LG screen and occasionally the Sprint screen. It intermittently charges when connected to power. Today, I hooked up it up to a PC and powered on and got the Demigod screen. Loaded dload mode, but the drivers didn't install. On reboot I got the LG screen with a security error and now it won't power up again.
Any suggestions? Seems like it may be hardware related.

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.
