Bootloop- Urgent Help REquired

So I am on a stock GT9500, suddenly today the phone restarts, gets stuck on the Samsung logo and keeps going into a loop till the Samsung logo.
Also, as soon I remove and insert the battery, the loop starts. I dont have to press the power button for it to start.
The battery was about 70% if I recall correctly. It wont go into recovery and I am unable to try download mode with odin as I am in Office.
Any help please?

Your only option is Odin given you have no recovery.

Weird boot loop - Black Screen of Death

In my T-Mobile Galaxy S4, I am getting weird loot loop. When I power on the device, It shows Samsung logo, and then go black. When I connect to charger, It shows "charging" for one second and go black. When I try boot into recovery menu, it shows it for a split second and go black. The Only place where I can see the display is "downloading" mode. I managed to put in downloading mode and flash stock ROM twice using Odin, and it was completed successfully, but then when I try boot device, it shows Samsung logo and go black, the whole cycle repeats.
I couldn't understand what is the problem at all. The Display looks fine in "Odin" downloading mode, and since I reflashed firmware, I am going nuts trying to understand.
Please help.

Hi,
Re-flash stock firmware should fix this (I hope it).
Sent from my GT-I9500

Try flashing stock again but don't check anything except f.reset time. After flashing and you see the word "reset" in the status window, remove USB cable, remove battery, replace battery, use button combination to boot to recovery, and perform a factory wipe.
Btw, the T-Mobile s4 forum is here: http://forum.xda-developers.com/galaxy-s4-tmobile

Samsung Galaxy J5 starts to go green after Smart Switch PC update.

I installed the 6.0 Marshallow Update on my Samsung Galaxy J5 Smartphone from Smart Switch on my PC. At first everything was OK. I plugged it, and it started downloading. Nothing unusual. When it ended, it said that the phone is restarting, so I should unplug it and plug it again, to see if it worked. The first unusual thing was that the phone didn't restart. It was just turned off. And I passed that because I thought I misread. So I unplug the phone from the PC and try to power it on. This is when the REAL weird stuff comes. At first, the "Samsung Galaxy J5 Powered by Android" logo shows up. Nothing special. Then a yellow-blue line shows up below the logo. I don't give it enough attention. After that, the screen starts to go green. Slowly turning green. . .The logo didn't disappear. My first reaction was to remove the battery, wait 10 seconds and put it back. I now try to charge it, to see if it happens again. AGAIN THE SAME! The yellow-blue line shows up, the screen starts to slowly turn green. I then wait to see what happens. The screen goes green. Completly. The screen needed a few more seconds to turn COMPLETLY GREEN. But I was soooo scared I took the battery and the charger off. I put it back up but this time, I wanted to go to recovery mode, so I can simply click "Reboot Phone". I couldn't. There was nothing I can do. I now have the phone without the battery and I want to know what is happening and how to fix it. I am really scared so I need help ASAP!

Hello!
I think you flashed other firmware than your phone model. Thats how it happened on my J500FN when i tried 6.0.1 firmware from J500F since J500FN didnt have official update.
Download a firmware for your phone model, 5.1.1 or 6.0.1 and flash through ODIN, then the problem should be gone.

This happened on my phone when I put 6.1 on via odin but then I simply tried a different recovery and the recovery was the problem
John

Anyone know how to fix this problem? I cant use odin because it wont let me go to recovery or download mode

This is happening to my phone with the exact same situation, but now I can't seem to connect to the pc with the cable - what should I do?

It happen because you use latest odin. flash again using odin 3.07 and see how it goes. It fixed mine. Had to double flash. First flash was giving me green screen. It won even pass the bootloader. Then enter download mode and reflash it using odin 3.07, it works like a charm now.

It's happen when you flash ur custom rom (only for bootloader lollipop) using bootloader marsmallow. The solution is ur phone must be support the requirements of ur custom rom.

My phone won't boot into recovery mode or download mode SM-G935F

Hi i'm currently stuck with a problem. This problem started i entered download mode and got a prompt saying "Installing a custom OS can cause harm to this device, do you want to install a custom OS?" I clicked on no and now my phone just keeps going to the Samsung Galaxy S7 Edge, powered by android screen. I have tried many solutions but none of them work. I have tried booting into recovery mode but nothing happens, when I try to boot into download mode it just goes back to the splash screen. Please Help! :crying:

You want to press VOLUME UP, power and home buttons. Hold until you see Samsung then release. You are booting up in download mode by mistake.

Stuck in logo after flashing stock. Can't boot into recovery. PC doesn't recognize.

So, I rooted and tried flashing the stock ROM (from Sammobile, same country, same exact model [SM-G950F], I already had the stock ROM and had never flashed anything else to the phone other than root, June security update, my phone had July's) to see if I could fix a problem that couldn't be fixed with any other method I had tried.
Everything in Odin seemed to go well, I got the PASS green box at the end. But then the phone couldn't go pass the Samsung logo when booting up. I left it quite a few minutes, before trying to boot into recovery mode and wiping data. Only to realize that I couldn't boot into recovery mode. In fact, I can't even turn the phone off. No combination of hardware keys works other than power button + bixby + vol down, to get into download mode. But that's of no use, because when I plug my phone into my PC (with the same cable and port I used before to root and flash the firmware into it) it is not recognized by Odin or the PC.
It just has the Samsung logo flashing slowly over and over because I can't turn the device off. By the time the battery dies out I'll most likely have the logo burnt into the display.
I also haven't been able to find any help online. Everyone's suggestion is “boot into recovery and wipe data”, but I can't do that.
Is my phone gone for good?
