[Q] Phone gets to lockscreen and reboots - Xperia Z1 Q&A, Help & Troubleshooting

I installed Words with Friends and for some reason the app gets stuck on a black screen. So I powered off my phone and turned it on again...... and now everytime it gets to the lockscreen it freeze up and reboots. Help?? I'm able to unlock the screen now, but after a few seconds or so the phone just freezes and reboots.
I have a Z1S so there is no hard factory reset available. It also freezes in Safe Mode so I have no idea what to do now.
Was able to get to factory reset in the phone so I'm fine now. If a mod can close this thread or something.

Stuck on startup screen after update | no root | can't factory reset

I got a notification that 4.4.2 update is available for me and I clicked yes to download and install it. I left my phone alone on charge while it was installing the update. When I came back to check what is going on, I saw that phone is stuck on a black screen and nothing happens. Orange led was off even though it is plugged on the charger. I forced restart and it stuck on the startup animation.
I tried to perform a factory reset, but when choose factory reset option from the boot menu, it shows a green update icon for a very short time and it restarts and gets stuck at the startup animation again.
I never tried to root my phone, I was just trying to install a regular update.
It seemed weird to me that orange led is off even though the phone is plugged. The phone only charges when it is turned off.
Any advice?

Major problem. Phone Stuck at start up logo

This morning during a call my phone shuts off for no reason. It is not rooted no physical or water damage. I tried to power it on it will vibrate than attempt to start get stuck at boot screen than eventually turn black. I tried booting into recovery to hard reset I will get to the menu do all the prompts and get the lg logo and back to black screen. I don't know what is going on. Is this a common issue? Admins if this is in the wrong section feel free to move it.

Not sure what caused the issue but if wiping from recovery doesn't work I would look into restoring phone with kdz file. Sucks to do that seeing as all data will be gone but hopefully you have a backup. If restore doesn't work you need to call T-Mobile for replacement

The replacement has been processed. Unfortunately trying to factory ? reset doesn't work because the phone ? wouldn't stay on long enough for that to happen. Love to know what actually caused this issue. Kinda kicking myself for not doing a weekly backup.
I actually got the same problem on mine but mine is rooted and was working fine but then randomly my phone is doing bootloop. I don't have terp installed and I'm I only able to boot up to software upgrade mode. Ive tried the step for format everything with holding the volume up n on button but after I did the reset stuff still does boot loops. Also another problem is that whenever I plug in phone to computer it doesn't show up, so I have no option to add roms or anything like tht to internal or sd card. Is there anyways too flash anything of the software mode, if so can you plz let me know thank you.

Samsuns S10 (G973F) "Phone is starting..." loop

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.

Booting Problem

Ive been using this for 7 months now. I flashed it from CN to WW successfully and was using it for 4 months up to this point. The phone's problem is that it always gets stuck at boot and loops for about 3-4 times before going to a complete state of unresponsiveness (black screen) even with force restart i cant get it to respond and have to wait for several minutes and try lots of times before it responds and it boots and again loops till it proceeds to black screen. It was completely random. I was playing some game till it suddenly freeze and rebooted , that started the loops. Sometimes at the boot screen with the ROG logo it shows strange white lines that wasnt there before, like its glitching. I've already done factory reset and still the same situation.
I sucessfuly entered the phone setup once and used it for like 10 mins after reset then when I rebooted it, it went back to looping and black screen. I hope someone can respond to this, I desperately need help.

[help] phone won’t turn on, black screen of death, stuck on boot.

I just want to say first thank you for taking the time to read my story and helping.
Phone gets stuck on boot logo.
Before the phone died i was laying a game and playing a youtube video in the background and was getting a call through facebook messenger.
Then game freezed or crashed then tried to soft reset which worked sorta then when it came back i saw the no sim notif up top the status bar and i can’t seem to turn on wifi and a system ui not working popped up i chose close instead wait. Can’t remember if I turned it off or if it turned itself off.
I can access the volume up+down+power bootloader and the recovery menu.
I don’t want to factory reset as i have no back up and I don’t know how to recover deleted data and I fear everything won’t be recovered.
