Unable to go into Recovery mode

This morning I was in bed browsing Reddit when my phone suddenly crashed and rebooted.
I put it aside to let it boot up, but after a few minutes when I looked at it the screen was just white. Rebooted it again, it then went into boot loop at the splash screen.
I attempted to get into recovery, but to no avail.
Attempted a few more restarts to get the phone up and running but no luck.
So I decided I must flash stock firmware onto it. Did that through Odin, seemed to be successful according to Odin, but my phone stays on the splash screen while it says "recovery booting" in the top left corner. After a while it boots up again, this time only the splash screen, no text in the top corner. But its stuck in a boot loop.
Flashed firmware and PIT file, then flashed philz touch recovery and still stuck on the splash screen.
Tried older firmware versions and still no luck
I'm at a loss as to what steps to take next..
Well, something must have caused that crash. Maybe hardware failure. Reason why it wont boot up. It can't be software related since it wont even boot up any software, except for recovery and download mode.
You might try flashing a different bootloader, since that's the thing that controls the OS booting.

GT-I9505 unable to boot; freezes constantly in Download Mode; can't flash anything

Hello,
my Galaxy S4 got soft bricked recently and I am looking for a solution for 5 days now and now I decided to ask you guys for help since I can't find anyone with the same problem.
I had Albe95 LolliROM 9.0 (15/05/16) [HPA1] flashed on my phone for about 3 weeks and everything was perfect.
I was using my phone when it suddenly restarted itself and it got stuck in a bootloop (SAMSUNG animation). After many attempts I could boot into recovery (TWRP) but it would freeze there and I had to remove the battery...
I could also boot into Download Mode so I decided to flash a stock rom (I9505XXUHOJ2_I9505OXAHOJ2_I9505XXUHOJ2_HOME.tar) which I downloaded from Sammobile. Odin would always stuck at system.img.ext4 but again after many attempts it workted and I had success. When it was booting my phone froze at "optimizing apps". So I had to turn it off and restart again, but this time the phone was always freezing at the first samsung logo and wouldn't go further.
I can still go into Download mode but can't flash anything because eather Odin fails (complete(write) operation failed) or my phone freezes. Sometimes when I boot my phone into Download Mode the screen would do strange things like flickering and weird colors would show in DL Mode.
So my problem:
- booting into Download mode after works though it freezes sometimes
- can't flash roms because phone is freezing all the time
The model # in download mode is 9505? Was the phone ever dropped? You're using the original Samsung USB cable to flash?

Thanks for the reply.
-yes modelnr is 9505.
-i have not dropped my phone recently. I mean its over 3 years old so of course I've dropped it but never really bad and it has no scratches or anything.
-I've tried different cables and samsung cable was one of them.
I also tried all ports of my laptop even tried another pc
Maybe flash the stock rom with a pit file?

I didn't try this pit file thing because I don't understand the meaning of it exactly..
But after many many Odin flash attempts I got a success with a stock rom 5.0.1.
I think I figured out what the problem is but I can't really tell why it's happening (Hardware broken maybe, but which one?)
So after the flashing the stock rom successfully the phone restarted and started the first boot but it froze during the samsung animation again...
I thought maybe if I try a lot of times eventually it will work, so I tried and tried and it always got stuck at samsung animation. (before every boot I had to remove the battery and wait ca 10 sec because otherwise the phone would not start booting at all)
I did not come further than the samsung animation so I removed the battery and placed the phone (I almost gave up).
But after one hour I tried again and this time it passed the samsung animation and got to the Optimization part of the apps. aaaaand it froze there again.
I thought maybe if I wait again for 1 hour I can pass the optimization part. So I did and it really worked. I got to the startscreen.
So the current problem is:
- The phone boots and makes it to the homescreen and freezes after ca 10 seconds. And also I have to wait for about half an hour or one hour to get that far. If I try again right after the freezing I can't get passed the Samsung logo.
What could cause this freezing? Maybe the cpu has to "cool down" in the one hour of waiting and freezes because it gets to hot? I really don't know what it could be.
Something on the motherboard, likely either CPU, EMMC chip, or GPU, is failing. Why or how I don't know, but I'd have a tech look at it.

Boot issue

I am having an issue booting my S7 Edge (US Unlocked)...thanks in advance for reading
Woke up in the middle of the night, checked a text, pull down menu froze screen, noticed battery at 1%...plugged in to charger
Next morning, black screen with solid blue notification light
Tried restarting several times with same result, but eventually it booted normally (one time)
Phone went back to same state...black screen, blue notification
Tried several restarts and eventually went to recovery mode...cleared cache, rebooted, no luck
Over the last day and a half I tried restarting many times with varying results
Always get "Rebooting Recovery...." on top of screen
Sometimes get Samsung Galaxy S7 Edge" screen, though most often not
Usually get the "Installing updates" screen, then "No Command"
Sometimes (rarely) I can get to recovery screen...though most often not
Sometimes in recovery screen I am frozen (volume buttons don't work for selection)
I can usually get into download mode
I've tried everything I can think of and find to get the phone to restart including letting the battery drain completely and doing a full recharge and restarting without SIM/SD
Any ideas on how I can get into my phone without a hard reset...i'd like to try and backup some files/texts first if at all possible. I haven't been able to get into safe mode
Any files I can load to SD or through ADB that would help?
Phone is stock...no rooting or roms (first time keeping a stock phone...go figure)
Thanks.
I've tried flashing stock firmware from updato and sammobile with no luck. Can never get past the "Recovery Booting...." screen. No help from smartswitch. Anything else I can try?
Having the same issue...
any help would be appreciated.
Tried flashing many times and got several different errors...often if failed on cache.img.ext4
I was able to flash BL + CP + CSC successfully, then flash AP successfully. Still had boot loop issues after that though, so not much progress.
Once I did get the "error...connect to smartswitch" screen, but smartswitch did not recognize device.
Not really sure where to go next from here.

SM-G935A Stuck in multiple different loops

Howdy, all! This is my first post on XDA, and it comes after days of frustration. I'm relatively new to the back-end of phones, especially android. What happened is this:
About 4 or 5 days ago, I woke up to my phone completely dead, despite being plugged in. I tried turning it on, and got stuck on the "Samsung Galaxy S7" screen for a while, and then finally a blue screen with the android logo saying "Installing update." That process seemed to end rather abruptly and then went back to the first loading screen, followed by a black screen, then "Samsung," and repeat. At this point I tried plugging the phone in to see if smart switch would detect it... and this is where my ineptitude with phones starts to show.
I didn't realize that smart switch has an emergency recovery mode under "file," (*sigh*) so when my phone didn't show up on the main screen I assumed the worst. After some google-searches, I went in to clear the cache through Android Recovery. I was still trying to save my data at this point, so I didn't just erase everything and start fresh. I regret that now.
After clearing the cache, I rebooted the system through the menu, and was stuck in loop with the first screen being all black, except for some blue text in the upper left hand corner saying, "Recovery booting." The screen would then flash back to a blue screen with the android logo and "Installing system update," and then go black and repeat the whole process. Getting back into the recovery menu was sporadic after this, but was possible occasionally. This is where my ineptitude REALLY starts to show...
Despite having my current rom version displayed to me multiple times on the recovery menu, I neglected to write it down or record it in any way. Instead, I googled "SM-G935A stock firmware," and was able to find a presumably helpful link on these forums guiding me on flashing stock oreo files through Odin. I say presumably, because in the hands of someone who actually has knowledge on this subject, the thread was incredibly helpful. In my hands, however, it seemed to create a monster. I flashed the stock files downloaded from the link, and all looked good- Odin gave a solid pass, and the phone rebooted to the normal initial two loading screens. And then disaster- another boot loop. But this time, I have no idea what firmware used to be on my phone before I started fooling around.
At this point, I've had one near success with a flash of SM-G935AUCS8CRK1 through Odin where I actually got a blue LED indicator for the first time, as well as the AT&T logo and chime. Now, however, it seems that I either get stuck in that loop, or back to the original "Recovery Booting," "Installing Update," loop.
The phone is not rooted. I don't have a custom recovery installed, and I'm not even sure if I ever got around to enabling developer mode through the OS settings.
ANY help is appreciated. I'm pretty sure I've made the problem significantly worse than it was originally, but I've at least learned a lot in the process- hopefully I won't mess things up this badly in the future! Thanks for taking the time to read through this mess!

Note 4 Stuck in initial boot screen. Tried everything I could.

My Galaxy note 4 is stuck in that "Powered by Android" screen when booting.
Model Number is SM-N910C.
Download Mode is the only mode accessible. Recovery mode is not available now.
It worked just fine running Sweet ROM just a few days ago but randomly stopped working.
After trying multiple re flashes of TWRP, I eventually resorted to just restoring a system firmware image from SamMobile.
I have the exact same results as before, but now the recovery button combo does not result in any error. The phone tries to boot up normally and is stuck as mentioned before.
Plugging it in charging causes the phone to boot up and then get stuck in that screen again. This is incredibly frustrating.
Any ideas are welcome. Please help me out here.
