@Jonnyredcorn Did you restore from a backup? If so try from a new device

Why nt make a clean flash and see if it persists or not?

I had this exact same problem, and assuming that you did a dirty flash (did not erase your data), this is why it's being caused
After flashing Android L onto your device it is attempting to run the "First installation" screen but is in conflict with booting up normally as you have already completed the setup.
To confirm this = Try "unlocking and locking" your phone with the power button, you should see the install menu flash up briefly, for a second or less, if that's the case then you're in the exact same situation I was in
There was an old fix for this, but isn't very reliable now, it's worth a shot anyway
"adb shell am start -n com.google.android.setupwizard/.SetupWizardTestActivity"
This will force the installation overlay on top of the black screen allowing you to "setup" your phone again despite already doing it.
If this fails then your only hope is a fresh reinstall

I don't believe I did a dirty flash. I was under the understanding if I flash the factory images it did to clean white I didn't do a clean wipe and recovery prior to booting into the bootloader and flashing the factory images. I did not restore from a backup this is my first time going from KitKat to lollipop I do not see the installation screen pop up when unlocking and locking my phone

Ah okay then,
I'd suggest attempting a reinstall
If you modify the flash-all.bat removing the "-w" command, which wipes your phone, you'll be able to retain any data currently on the phone.
But as you've said you think you've wiped over it anyway, just complete another wipe over the device and flash it again, better yet download a fresh ROM first

OK so my issue was I forgot to flash the userdata.img which caused me to dirty flash. I just redid the whole thing and it's working it's working perfectly now thanks for all your help guys

[Q] I don't even know what to name this problem...

So.. it all started with google services framework.

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It kept crashing every 30 seconds. I tried to clean cache, clean data, force stop, reboot phone, remove google account in "Accounts & Sync", everything you can find on the internet (except for an actual solution, which i still didn't find). I thought re-installing it would help. I found an apk for Android 2.3.4, and installed it. I rebooted the phone. I had the same problem with play store a couple of months earlier, and I thought it would be the same.
Android didn't boot after that. Tried removing battery, rebooting phone, nothing. Had to do a factory reset. Once the phone booted (after factory reset) i got to the part where I get a green android with a message "Touch the android to begin"
I tried factory reset a couple of times, with and without sd and sim cards, no luck. Tried tapping the corners, but nothing. Found some other **** online, same result.
Why did you try to install an OS using an apk? It sounds like what you should have done was reflashed GAPPS which should have overridden the framework you were having a problem with and solved the problem. If your phone is not rooted, the only way you can fix it is to boot into recovery and reset from there. If you do have a rooted phone, it'll probably be easier to go into CWM and reflash your ROM.

Tab 2 Problems(Need help ASAP)

So my friend gave me his Tab 2 7.0(P3100) for me to check out since it has problems to see if I can fix it.
And I checked it out and here are the problems:
The tablet constantly crashes. TouchWiz ran for a few seconds(Very laggy) before it reboots and it repeats again.
You may though factory reset would do the job.
However I tried to factory reset via the recovery. The recovery shows something unusual as seen below:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So when I wipe data/factory reset, the recovery goes through the process as normal. But once it reboots, it does NOTHING AT ALL!
Then I reboot into safe mode and tried to factory reset in the settings. Once I went to backup and reset and tap the delete everything, nothing happens even after I tap the delete everything multiple times.
Oh, the thing also crashed in safe mode. It ran longer than the normal mode though.
I was unable to factory reset the thing.
However there is another weird problem. When I set a setting like connecting to a wifi network, uninstalling an app and changing brightness, after it reboots, all the settings I applied are reverted. So the wifi network is forgotten, the app I uninstalled is back and the brightness was set back to what it used to be.
I worked with multiple devices in the past and I've never seen anything like this.
Have anyone encountered a problem like this. And please give any solutions if you do.
I do have a feeling the problem is not normal but you can help out.
I need to return the tablet the next day after posting this thread so any help is appreciated.
Thanks for your time.
UPDATE
I tried reflashing the firmware using ODIN and this happened
And you thought when it fails halfway especially when the system.img is flashing would brick the thing.
It doesn't. The tablet still reboots and same thing happens over and over again....
I tried flashing the same thing again but still the same results.
Probably eMMC was set to read-only memory.

but after flash super user zip phone stop work at bootloader warning
same thing happen to me too..plz someone answer.
Prior to flashing supersu.zip, open twrp>advanced>terminal and enter (without quotes) enter the command
Code:
"echo SYSTEMLESS=true>>/data/.supersu"
Now SuperSU would install in systemless mode. The latest betas automatically install in systemless mode (I am using 2.74). Check if now it works.
Broadcasted from Zeta Reticuli
@Gravemind2015 is correct, that is the command needed to make it work... note that since you already tried flashing several SuperSU versions the old way, if it continues to be a problem you may need to reflash the factory images and verify booting prior to trying the mentioned systemless method.

I had the exact same issue on my 16 GB xt1540, running stock, fresh 6.0. Trying to root with SuperSU's (over TWRP), several versions up to 2.74, earlier versions down to 2.4 ish... I'd freeze at boot logo every time, after what appeared to successful installs.
After reading somewhere about someone else's luck, I gave 2.65 a go, a version I must not have tried (and one I notice is not on your screen shot), and it worked. I certainly didn't expect it to, and obviously it could be completely coincidental. I'm pretty sure, however, that I did nothing differently on that install to what I had done other times.

Bootloop on Samsung Galaxy S3 with TWRP and Lineage OS 17.1

Hello guys, so basically you are my last hope since I cannot find a solution for my problem (at least with my level of knowledge).
Lets start from the beginning: I (someone with no experience in this topic) decided to try out a new OS on my old Samsung Galaxy S3 since a lot of apps stopped working on Android 4.3. I tried a tutorial on youtube on how to install a new custom ROM. I installed TWRP (3.5.2_9-0-i9300) and later with the help of TWRP Lineage OS 17.1 (an unoffical version for my type of phone) and everything worked perfect.
I started to download all apps I need and to customise my OS. In the end when everything was set up I decided to do a full backup using TWRP and thats where the problem started. In the development section I checked the function, that when you press the power button you can directly boot your phone into recovery mode. So my phone rebooted and ended up in a constant boot loop where at first the Samsung Galaxy logo appears (first picture) and then TWRP appears (second picture) and this process goes on and on...

"lightbox_next": "Next",

"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Sadly there is no way to get into recovery mode since this loop just continues. If tried it many times also with taking out the battery and putting it back in. The only thing I have access to is the download mode.
So my question to you: is there anything I could do in the download mode to solve this problem? I saved the important data before so a full wipe wouldnt be a problem. Maybe I can do something with odin?
I really hope you can give me some ideas to try out. Every help is appreciated. Thanks!
Try reflashing a stock ROM first of all.
Then reflash TWRP. Make a TWRP backup (especially the EFS ! That is a "must-do first and foremost" !) of your working system and progress from there.
And in the future, instead of reinstalling all your apps piecemeal I strongly recommend you use Titanium backup (paid version. The free version is very limited), that is a wise invesment for the small sum it'll cost you
@Snakeforhire reflashing stock ROM worked, thank you so much.
I will take a closer look on Titanium backup. Used it in the past but with root access. On the new Lineage OS I dont have root although it shouldnt be hard to get from what I read.

Sounds to me, like part of the storage may have suddenly failed or been damaged, causing your device to lock up and after a reboot, triggering this unusual state. Part of the bootloader is likely not getting read or written to properly, so installing fails only after partially writing to the device, and it refuses to boot. You could try a repartition and complete installation - that might also make it worse though. I've seen the blue screen of mild annoyance many times - not sure about the falling android, was there any text? If so, what did it say? The firmware does contain screens for various diffrent panic states, resembling the one you mentioned. I would encourage you to do some more research on those and look for patterns in the way it fails - or doesn't - when flashing other parts of the firmware package. Don't even bother with SmartSwitch - in my experience, it fails at anything the errors tell you to use it for. Also, simple issues like a faulty cable or the wrong firmware can often be overlooked - so make sure those are fine before starting to experiment.
