sm-t820 galaxy tab s3 stuck in recovery booting with black screen - Samsung Galaxy Tab S3 Questions & Answers

Hi, can anyone help me out?
I have a Samsung galaxy tab s3 -(Sm-T820 ud) rev. pie9.
I changed the battery because it would not turn on, when it tried to do so, it would just shut off,(never passed the galaxy tab page).
now with the new battery fully charged although it never shows the battery level, the tablet wont turn on and is stuck with the message recovery booting..... and with black screen, it just turns off and then on over and over.
I tried to connect to my pc but the tab is not detectable threw USB cable.
attached is a photo of the screen.
Please if anyone can give me some suggestions on how to get it up and ready again.
Do I have to reinstall everything or what????? and how to do it and what to use.

S3 4G wont start up

Hi guys im not sure where to post this so im just going to post it here. My s3 got stuck on the boot up samsung galaxy s3 screen so i pulled the battery out and restarted the phone and now it doesnt start up at all its stuck on this static screen i cant get to recover mode but i can get to download mode i was just wondering what the problem might be and if there is a way to fix the phone? I have attached a photo to show you what it looks like.
That's extremely odd. I've personally have had an issue with my old phone with the startup with it giving me a "Fail error", but I can suggest that when it does that, keep the battery out for 10-20 minutes to make sure it stays off. Then put it back in and turn on the phone and see what it does. If that doesn't work I suggest you just either send it in for a new phone or have someone look at it.
ive tried leaving the battery out overnight and still nothing could it be a corupt firmware issue because the phone was playing up before hand for a couple days where it would just freeze and would need to be turned off and on, so i did a full reset cleared everything through recovery mode.

Galaxy Tab 3 How to determine if LCD is bad

I recently replaced the USB charging port/ribbon in my Tab 3 10.1 (GT-P5210) Stock firmware, never rooted or modded in any way.
When rebooting the tablet, I noticed a bit of green specs and lines across the screen then it went black.
I have maticulously made sure each ribbon cable is in correctly and I can access the memory of the tablet via USB cable from my computer but I cannot get anything to show on the screen.
Is there a way to troubleshoot if this is the LED that is bad?
I followed some of the other threads on here and tried the power drain method, booting into recovery or download, etc but can get absolutely nothing to show on the screen.
Wrong thread.

Please help

Hi, I currently own a samsung galaxy SIII for 4 years now.
But recently, it got stuck at the samsung logo and it wont turn on, the moment I put in the battery, the logo flashes every 3 seconds and thats it. I had sent it to repair, but they say that it is corroded with water, and is beyond repair. I only wanted to get the files, photos and notes out as they are really important to me. Is there ANY way to get it? Anything will do, as long as I could retrieve my files. Recovery mode is impossible as the screen came out for a bit, but it went back to the logo again. So when i press the volume up or down, nothing works. I tried connecting it to my computer, but it says error.
My phone is not usb debugging enabled, has no sd card, not rooted, and no backup. I really regretted not doing any of these. Please help me. Thank you for reading this.

Galaxy s4 after LCD replacment

Hi,so i replaced LCD in my I9515, I've been doing this with youtube tutorial. Before 1-2 weeks ago my phone boot normally but i couldnt see anything due to broken LCD. In store, guy took my battery and connected it to a naked motherboard and lcd to see if it's working. After replacment when i try to boot it's stuck on Samsung Galaxy S4 logo and wont boot further. I can go into download mode, computer and odin are seeing connected phone, but i cannot boot into recovery it's just showing blue "booting recovery" and nothing happening. When I charging it, the grey battery pops out, but when i unplug it the battery is still there like it's still connected. Sometimes when i try to turn it off when it's stuck on galaxy s4 logo it's turning off then on by itself like 2 or 3 times. Any ideas how to fix it? It's hardware or software problem? In a minutes i'll try to flash stock soft from sammobile. Phone was never rooted and no custom roms were installed.
Thanks for all help.
EDIT Flashing with ODIN not solved the problem
EDIT Now phone doesnt show battery when connected just one vibrate and screen is blank, and when i try to boot it while connected it's just vibrating and still black screen. When it was connected to pc it was vibrating every 2 seconds. When I try to boot it's by itself trying to boot recovery but it's not booting and blue "recovery booting" just hang on top of screen and nothing happening.
EDIT After restart by volume down in download mode S4 acts like in the beggining of problem
EDIT It's getting hot around processor when charging (about 5-10 min)

Phone restarts when removed from charger.

Hello, I have a Galaxy Note II sgh-t889. The phone worked perfect until I recently flashed it to Android 6 with cynogen mod. The phone worked fine for a few weeks, now the phone only powers on when connected to a charger. When removed from charged it goes back to the Samsung note II logo screen and won't boot past. I don't think it's a battery issue as I can boot in bios and it shows the battery is %95 full. It will sit on the logo screen until charger is plugged in, then will boot fine to OS. I've factory reset multiple times to no avail. I've read other forums of users who experienced similar issues and have narrowed it down to a possibly corrupt flash. The problem being, when connected to my pc the phone won't boot to home screen, it just sits on the logo screen. (So Odin does not detect the phone) The solution I was told is to flash it back to stock/oem rom. The problem is I can't get it to bboot to home screen when connected to pc, only on wall charger. If someone could please give me some insight, I would be more than grateful. I don't have the money atm to buy a new phone, so my only option is to try and get this fixed. Also I don't have an external sd. Can someone point me in the right direction of what to do ? I'm so stumped and I can't stand having to pack my phone around on the charger all the time...
