Updated to lollipop, now restarts after powering up every time - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

I have not rooted or anything yet. I was planning on waiting for lollipop...
So I installed the OTA update. S5 starts up and gets to the lock screen, then after a few seconds it restarts. This happens every time. I have about enough time to put my password in and begin to open an app and it restarts.
Any suggestions on what to do? I've tried booting in safe mode, same issue happens.

I have same problem , started my OTA 4.3 upgrade 40mins back . My phone keeps restarting with "installing system update ". Any idea how can i stop this ?
Update seems to have finished, bootloops after inputting user password to unlock screen. It's a short boot right back to the password screen again.
Was stock, rooted, unlocked, 4.3 was OTA update

I got really lucky somehow, in getting the phone to work and managing to keep my data.
I don't remember every step in order, as I'm sure lots of them didn't do anything, but eventually I just reflashed every part of the factory images EXCEPT userdata.img as I (correctly?) figured that would erase my ****.
Wiped cache a few times from recovery as well.
Had a couple scares - at one point the LED turned RED during a couple bootup attempts.
First time after the 3rd round of flashing (including system.img) it would not boost past the X. Had to wipe cache in recovery again.

Exact same problem with N4. Have ota'd Galaxy Nexus and Nexus 7 no problems...

Update:
After waiting about 10-15 mins I eventually reset the phone by holding down the power button for 10 secs. It then moved to the "updating apps" screen and eventually rebooted to the Nexus "X" logo. But it hung at it the X logo for about 15 mins. I again lost patience and restarted again. It finally booted all the way up to the lock screen. I now have 4.3 and it seems to be running fine...
Just wanted to share my experience as I had the same problem. It kept saying 'installing system update...' in a loop. Then I pressed the power button. It got turned off. I turned it back on and it got stuck at X logo.
Then I booted it up in recovery mode. It again said installing system update but only once and then it started updating apps and all went fine.

[Q] OTA Update and Reboot Loop- Attempts to install update, fails, and repeats

Ever since receiving an OTA update a few days ago, my phone was never able to successfully reboot again. Instead, it does exactly this when I turn it on: Samsung logo appears when booting, then the At&t logo with the word "installing..." or "updating..." along with a loading bar at the bottom appears. The loading bar reaches 100%, but then it will say "update failed", and it reboots and the same process happens again. I've let the phone run on it's own for several ours to see if it'll ever snap out of the loop, but it just stays in the same never-ending cycle of constant rebooting and updating. My phone wasn't rooted and worked perfectly fine before the update, so I suspect something went wrong while it was updating. I tried pressing the home, volume, and power buttons in attempt to initiate a recovery boot and do a factory-reset, but nothing happens. And I've tried replacing the battery, SIM card, and micro SD card, but there's still no change. I still am, however, able to set it in ODIN mode, but I'm not sure what to do since I'm not techie/literate. Please help, I don't know how to get my phone properly working again.

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...

Trouble flashing marshmallow roms

Hi all
I'm using a snapdragon n10g note 4. Whenever I finish flashing any android 6.0 ROM(with factory reset and everything) I get the following problems:
The phone shuts down at the boot screen-while the boot animation is playing. Not restarting or anything,it just shuts off. I can try to turn it on again but it just shuts down again.
Then, in the rare occasion that it DOES boot successfully, I get a "no sim card detected". And I can't really reboot to try and solve it because the first problem will show up again...
Have googled a lot but didn't find anything. Thx in advance.

XT1564 unable to reboot properly for OTA

I have a stock moto x play whose hardware sku is XT1564. It's on android ver 5.1.1 and system version is 23.21.25.lux_lra.en.US
I have not performed any soft mods or alterations, be it root or bl unlocking.
The only thing that I would think is different than normal is that the phone is encrypted, so it asks for password whenever it boots up.
I got a notification to update to 24.74.5.en.US a few days ago and decided to try doing it today.
It downloads the update fine and when I press on the notification for it to start the update process where it says it needs to perform a reboot to update it goes into a "phone will reboot in 10 seconds" screen and when countdown finished it shows the "shutting down..." popup that appreas when you try to shutdown the phone.
Then the phone stays with that popup until it finally shutsdown like 4 minutes later on what appears to be a hard shutdown because it doesn't reboot. I have to manually power it on and then the phone starts up normally asks me for my password and about a minute after android fully loads the phone tries to shutdown again without any input. And then it just keeps doing that until I boot the phone into fastboot and try to get it to bootloader, where it shows the dead android logo with a red yield sign and promptly shutsdown. Then when I start the phone normally it shows an "update unsuccessful" screen.
Anyone have any idea what might be the problem?
I've been thinking it might be the encryption but IDK. Also I've checked the thread with the firmware versions and couldn't find mine there. Is there a way I could dump mine for backup in case I **** something up trying to get OTA to work.(without unlocking bootloader and rooting, of course)
Now the update has stopped appearing and I can't get it to recognize there being an update for this device.
Fudge!
