Bootloop- Urgent Help REquired - Galaxy S 4 Q&A, Help & Troubleshooting

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.

S4 I9505 stuck in bootloop, does not boot to recovery, only download mode

Hello!
This morning my s4 decided to randomly power off on me whilst I was using it, and now it wont power back on without looping on the bootscreen where the white text "Samsung Galaxy S4" appears. I attempted to boot into recovery, but I just get the blue text "recovery booting" in the corner with no action at all even after 10 minutes. Download mode works, but even after reflashing the stock firmware i'm getting the same issue. The battery appears to be functional as normal, charging up and displaying charge in my old s4. Please respond with any ways I can potentially get it back up and running (even if I lose all data) ASAP.
Thanks!
Try nand erase all + stock rom, it might work, otherwise try an other battery.

Cant enter recovery or download mode on Note 3 SM-N9005

Hello
So today was planning to flash with a new ROM, so i started to do a factory reset from with in android, nothing happened
so i reboot the phone to enter recovery mode to do it from there, using Teamwin for that. But when booting up, getting the message entering recovery mode 5 sec later i see the logo for Teamwin and here it stops.
The logo keeps flashing every 4 seconds or so. Have tried without Sim card, done the battery thing where i remove
it and hold the power button for a while, but all end up in same, the teamwin logo flashing
As far as i can see i canĀ“t enter anywhere to flash the phone as the only thing i get is a flashing logo...
Also Odin does not detect the phone via usb either
is there a way to resolve this?
Thanks

Help!! phone is stuck in bootloop

Hi guys .. so i downloaded a custom theme from here ( dna aos-p black ) .and it worked however when i restarted my phone it was all messed up so i went to reapply it and then my phone restarted and now is stuck in boot loop.. it shows flashing Samsung logo and then optimizing apps and the turns off and repeats..
Phone is on android 8 with may security patch ... PLEASE HELP.. And thanks..
if memory serves you need to:
- while the phone is booting - once the Samsung logo starts appearing, press and hold "volume down + power button"
if it doesn't reboot then try playing around with your timing - when to start pressing both buttons.
if you get the timing right the phone should reboot into download mode form where you can flash the latest stock ROM

I've gotten myself into many a boot loop while flashing ROM's that didn't "sit well" with my SM-G9500.

J510FN Stuck on galaxy logo while turning

Hi,
As in the topic, I have J510FN who does not want to turn on. Displays the logo of the galaxy J5 2016 and even without showing the next Samsung logo it resets and the galaxy logo pops up again.
I tried hard reset then uploading a new software by odin.
The upload was successful, however, 32% of "installing system update" pops up "Erasing", the phone resets and the galaxy logo pops up, after a while the phone turns off. When I turn it on, everything goes back to the starting point, ie in the circle the logo galaxy -> reset after a moment and again the logo galaxy.
Recovery mode works, the bootloader works. The phone responds to the start-up and does not want to "go" further, ie to the Samsung logo and turn on.
Please, help, maybe it's an android problem, not a software? I do not know what to do

Try flashing another kernel like quasar and if it still doesn't boot probably the software.You could try flashing another rom to see if it boots if quasar doesnt boot it.Failing that you probably need to install firmware again with odin

My phone is stuck in bootloop and keeps going to an 'erase' screen

I tried to root my device trough odin. Odin said it was succesful, but when i turned on my device it said someehing like 'vertification failed, you have to reset your device'. So i tapped the button 'reset'. Then my phone restarted and its now stuck on a boot loop with the 'erasing' screen. It just goes to a blue screen with the android logo and beneath it it says 'erasing'. Then after a few seconds, it restarts and turns back to the screen again.
I cannot get into recovery mode, because you'd have to do it with the power button, volume and bixby button, but the second i try to do that, it just restarts and starts the loop again. Even when my phone stopped with the bootloop and just shut down, when I hold my power button it just restarts the boot loop... I already let the battery drain but then still, it just happens again.
I can only get into download mode, but thats all. I dont know my build number. I already looked at the box my phone came in when i ordered it, but all I could find was:
- an IMEI code
- an S/N code.
- a long code existing of numnbers only.
None of these codes I think were build numbers, only the S/N code contained letters.
So I dont think i have my build number. I cant get into recovery mode since it just starts the bootloop.
Please help

I hope my phone isnt bricked and this can be fixed.
