Samsuns S10 (G973F) "Phone is starting..." loop - Samsung Galaxy S10 Questions & Answers

Hello,
My device (S10, SM-G973F, Q - Android 10, v. 20200203, TWRP recovery) is Magics rooted and was working fine till last night. After phone went off to battery drain, i put it in charger, but this time forgot to hold down combination of three buttons to boot rooted (I thing for the first time since my root I forgot that) - so phone started "without root activated". So I've restarted phone holding right buttons this time, but phone cannot get through screen unlock. I put in my SIM PIN, then, on the "Screen unlock" screen, when I enter right key, phone immediately locks itself. So I enter Screen unlock key again... And it locks again. And that is infinite loop.
So I decided to restart phone "without root activated" and here I got through. My thought was, if there is problem with Screen unlock, lets turn it off, right? Well, after I turned off Screen lock and restarted phone "with root activated". And now it doesn't even offer me to enter SIM PIN! After Samsung logo is "loaded" my wallpaper appears with "Phone is starting..." loading bar and after two seconds there is Samsung logo again and "Phone is starting..." - a loop. It eventually keeps looping for couple of minutes, then phone reboots itself.
Still, I can boot without root.
Any ideas on what is going on? Shouldn't it help to alter some Samsung security APK file in TWRP or so? Cache wiped, no effect.
I just don't want to go through reinstalling whole phone.

[Q] Galaxy S3 GT-I9305 Boot loop problem.

Hi all.
So my girlfriends S3 started something weird this morning.
Last night the battery ran flat, so obviously it was put on to charge. The phone was off while charging, but, instead of the constant icon of a battery charging, the icon would come up and disappear, and reappear, and never become fuller.
When we tried to start it up this morning, the Samsung GT-I9305 screen would come on, and then just disappear and reappear, same as the battery icon.
The phone has not been rooted, no custom roms have ever been attempted, it is as stock as the day we opened the box.
First we tried leaving the battery out for about 30 mins, same would still happen.
Then I removed toe sd and sim card, removed the battery, and tried starting with and without the sim card. The sd card has not been put back. Same thing would still happen.
After some searching, I tried getting into recovery mode by pressing and holding power, volume up and the home key. This worked once, where I chose the restart device option first, but since then I cannot get the recovery mode back again.
I read something about a 'safe mode' by pressing power, home and volume down. This gets me to a screen where I am asked if I want to continue, by pressing the volume up key, but no matter what I press, the device just goes back to the GT-I9305 screen looping.
I wonder if maybe trying a different battery would help?
Any other suggestions on how I could factory reset the device?

Screen won't turn on after 0% battery shutdown

So I sideloaded 5.1 and was fine all day long. Was down to 8% then I notoced the 1% warning 30 seconds later. It shut down before I could plug it in. I booted up and everything seemed normal but the screen wouldn't turn on after the boot screen. I could take a screenshot and power it off but that's it. After a few times cycling it, It started going into the boot as it did when I first installed the update. Optimizing apps, I figured that would fix the problem but sa,e black screen. I tried booting into recovery mode. It just shut it down when I chose that option. I can see the time and unlock screen when I wave my hand over it. Unlocking it does nothing. I get red LED when I hit the power button one time.
I ended up doing a system wipe and it's back to normal now. I'd still like to know the solution in case it happens again.
If it happens again try first to reboot by holding power and volume down buttons for 10 seconds and/or wipe cash
I am having the exact same issue. Has anybody had a luck resolving it short of a factory reset?
My phone battery died last night. I plugged my phone in, let it get about 15% charge, then tried to turn it back on. The phone boots like normal, but after the boot animation goes away, the screen is black. Active notifications still seem to work, and I can hold the power button to get the Power Down option. I can boot into the bootloader & access recovery just fine. However, my phone is fully stock (no root, no bootloader unlock, no anything). I can't seem to access ADB when the phone is powered normally (ie, when I'm at this mysterious black screen), but it's possible that USB debugging isn't even enabled.
So far, I've found a bunch people who've said a full factory reset will fix the problem, but I'm looking for another solution, or at least a way to grab my data before I reset. Since my bootloader's still locked, I can't seem to use fastboot boot to boot into TWRP, and I can't find any other way to access my data to copy it off the phone. I've tried wiping the cache using the stock recovery to no avail. Any suggestions?

Please stop bumping up every topic that says black screen with the same copy and paste message. Once was enough!

[Q] My Z1 is completely DEAD

A few hours ago i try to Hard-Reset my Z1 because it keep restart it self while im using it. After i press ERASE ALL DATA or something like that buttons the phone went off and start again with android logo on it with some loading bars underneath. After a few minutes the screen went off, the phone restart and stuck on the booting screen. so i tried to manually restart it with long pressed on power key, didnt work so i use the OFF key in side the sim tray panel. It work and the message Android is Upgrading appears. Optimizing Apps 1 of 3. After it go through 3 of 3 the phone restart again. Same thing appears but the "1 of 3" turn into "1 of 2" AND then it repeat with 1 of 1 apps message. the screen went off again then boom! it's dead. No LED lights, cant turn the device on, charging doesn't work, PC Companion cant detect the phone. I try the "Repair device" options but still not working. Power key+Volume Up doesn't work, OFF key in the sim tray panel doesn't wok also.
Anyway i can do to bring it back?
Ps.Sorry for my bad English

[Q] error updating to lollipop (solved)

Details:
moto x purchased from web site, for use on Tmobile
i'm currently deployed. Lucky enough to have WiFi on base and T-mobile so communication home this deployment has been amazing. Saw lollipop came out today. downloaded it. installed it. phone boots up with the regular "TOMMYBOT Mobile" and then the spinning M worlds. then it gives me the password (for the decryption). it took a min and then said some error about corrupt files and that i needed to factory reset my phone. so i pressed the button and nothing happened... so i powered down the phone. and then everything started up the same. but when i put in my password to decrypt it takes a minute and then says starting android.... and then the screen goes black. tried 5 times. longest i waited was 30min. (left it over night now, so 6 ish hours)
i can start my phone pressing the power and volum down and it brings up a fastboot menu? but even from there the factory reset option just boots my phone back up as if i pressed the power button.
any help is appriciated.
thank you,
tom
Edit: followed these instructions (cant link, motorola global portal)
and a matching youtube video and i get stuck at the dead android with the triangle "!" sign mine says "No command." under him and i cant get the next menu to open
asked for help here (link motorola forums help) they suggested verizon assistant app. the program
i've treid 3 times now. each time the start repair makes a command "getvar all" come up on the bottom half of my fast boot screen. and then thats where it stays. the "Repair" button on the right does not become clickable.
Solution:
once on the dead android screen to open the next menu it was press and hold volume up AND power for 3-5 seconds together .
from there i did the data wipe/factory reset and booting up i'm already on lollipop. of course all un clouded data lost but i'm just glad to have a phone again.

[Q] ATT Moto X 2014 Freezing Constantly

Hello all,
I got this phone about a month and a half ago, and since I got it I've noticed a lot of freezing and crashing (more so after the 5.1 update).
Some examples:
-I try unlocking the phone from active display and the screen goes black. The only way to get out of it is to hold the power button to restart.
-Sometimes the phone freezes on the lock screen randomly, and when I pick up the phone to look at it, the time is wrong and I can't physically unlock the phone, only turn the screen on and off, leading to me having to hold the power button down to shut off and restart.
-When on some apps, like twitter for example, the phone freezes, and I cannot do anything except turn off the screen by pressing the power button. When I try waking the phone, it stays black or sometimes theres a flash of the screen I was on before, and then it goes black again. Only thing I can do here is hold the power button down until "Power Off" shows up on the screen, and I press that to shut the phone off.
Today I cleared the cache, and since then the phone has froze once, causing me to do a hard reset. What should I try next? Any idea what the problem could be?
Thank you for the help.
I have pretty much the exact same thing going on. It started last night... I first noticed I had some charging issues where the phone wasn't charging very quickly after the battery died (after a day of heavy use). I let it sit for awhile, then it booted up, and it showed the motorola splash screen. It gets all the way to the lock screen, although I'm unable to unlock the phone. The screen goes dark. It appears to still be getting texts and the like- although this screen blackness issue makes it so I can't unlock the phone. The one thing I can do is hold down the power button and turn it off. I've tried loading fastboot and doing a factory reset, although nothing appears to happen and it boots the same way. The other thing about it is that it appears to be running hot- way hot. Any ideas? I'm running stock rom, Verizon network, just updated to 5.1 when it came out last week.
