Galaxy S8 freezes then gets stuck in a bootloop! - Samsung Galaxy S8 Questions and Answers

I tried flashing a bootloader and new ROM but it freezes.
- I can get into recovery mode
- I can get into download mode
everytime I try something it freeezes, it even freezes when I try factory resetting it in recovery mode.
would REALLY appreciate some help, thanks.

Is it completely stock? If so it sounds like your phone is on its way out. My s7 did this and the motherboard eventually died. Take it back to Samsung.

[Q] Samsung Galaxy S4 sph-l720t (sprint) stuck in bootloop

I just got this phone alittle over a month ago. Today at work, my phone randomly shut down and started continuously restarting. The phone will vibrate and boot the logo, then turn into a black screen, vibrate again, and restart. I had not modified my device at all. Just downloaded your typical apps like anyone else. I already tried taking out the battery and letting it sit and booting in recovery mode and wiping the cache and restoring to factory settings. I also tried to use odin to flash what i think is my firmware onto the device. I wasn't able to figure out the firmware of the device before I did it so i sort of guessed based on the model. Though all i did for this is download what i thought was the firmware, put it in odin3.4, entered download mode and plugged my device in and let it download. I didnt do any rooting or enable debugging/disable debugging before i used odin. Did I miss a step? Does anyone have any suggestions of something I else do. I am so confused on how this happened to my phone!

Bootloop and firmware upgrade encountering problem I9505

Hi,
My galaxy S4 decided to poop itself yesterday. I was browsing my emails and the phone restarted by itself. . but then it kept restarting over and over again (Boot loop). The phone felt hot, so i took the battery out and left the phone for a while.
Once i put the battery back in, the phone kept boot looping. I managed to get it into safe mode and make sure all my photos were safe – I've just returned from a holiday in Hawaii, so this was very important to me.
After i was able to make sure photos were backed up on the computer, i cleared the cache partition and even did a hard reset. The phone kept boot looping. My phone now gets stuck on the "Samsung Galaxy S4 GT I9505" start up page. I read about issues with the power button, so even atempted to open the phone up and wiggle the power button around a bit by squeezing it with some tweezers. This made no difference. I've even swapped batteries and tried charging it.. this also doesn't work. Currently my phone has the "Samsung Galaxy S4 GT-I9505".
I have been on whirlpool forums and it was suggested that i reinstall the firmware through odin.. i did, but with great difficulty and many attempts. My phone was able to boot up and i was able to send one message and make one phone call before it went into bootloop again or just switches off and doesn't want to be switched back on again. When the phone was on, no sound was apparent when a phone call/text message came through for testing. I've retried dowloading the software on odin, but when i try to switch my phone on it says "firmware upgrade encountered an issue. Please select recovery mode in Kies and try again".
I've also tried putting the phone on the charger and no sound or green battery coloured animation comes up on the screen now.
Please somebody help
It was the latest stock firmware from sammobile.com that was flashed to the phone? Was the phone factory reset from stock recovery before booting the phone after fllashing with Odin?
As far as I know it was the latest unbranded firmware from sammobile.com.
A factory reset was one of the first things I did after starting the phone up in safe mode and trying to recover files.
The phone has never previously been tampered with. I've only ever upgraded the software through WiFi or Samsung kies. Using Odin was a learning experience for me.
Maybe the factory reset needs to be done from the recovery screen rather than from the ROM settings?
The factory reset was originally performed from the recovery screen. I can no longer get into recovery mode though. It only seems the phone wants to get into download mode
Have you tried flashing a ROM designed for a particular carrier in your country?
This is going to sound silly.. But I thought that's what I was doing when I went through Odin and got the firmware from sammobile.com
Which version of Odin and firmware was flashed?
What errors occurred during the flash process according to the Odin log?
Tried flashing with a pit file?

Verizon S7 Keep Freezing When booted into Android

Hi everyone.
I've got a g930v last year, someday it freezes itself, I really haven't done anything, It just keeps freezing when it passed the booting logo screen, even boot into safe mode...
I've done factory reset, even re-install the stock rom on it...
I would be grateful if any idea comes up...

S10+ keeps restarting, doesn't even go past Samsung logo

As said in the title, it's in a permanent loop of trying to turn on, showing the unsafe bootloader warning, getting to the Samsung logo, and then shutting off and trying again, all on it's own. I tried first by using the usual, but it won't go into bootloader, nor recovery mode. When that failed, I let it keep going at it until the battery was empty, and tried then. It still started the loop, but then it ended because it didn't have enough battery to continue and shut off. After that, I tried connecting it to the computer, but the moment I got the USB in, the phone tried to turn on, and started the loop, again. Even just connecting it to the charger, it tried getting on again.
Can you get into download mode? If so, just use ODIN to reflash the stock firmware. That should fix it.

Bootloop issue with G900V

I was using the device just fine, no problem. Then when I restarted the device for refreshing, it got stuck on bootloop, right stright to Samsung logo, not wait until the blue dot appeared, and it got bootloop after 1-2 seconds no more no less. The more scaring thing is that it completely got bootloop even when I attempted to boot into recovery mode, and I do have to plug my phone ( But at least it didnt bootloop when I was in Download Mode ). Yes, I did try Odin method, and it couldnt work. I tried the latest version, will try on older version to see if it works or not. The most weird thing is that the software at my Android before getting bootloop was G900F, and the back is still the same. I dont assume the back was resticked, but when it comes to Download Mode, it shows up as G900V. I dont know what to do now. Can anyone figure it out? I cant ****ing stand out anymore with Samsung old modem anymore. This is the second time after buying Samsung Galaxy Win. Ty
