Black screen, bootloop, restarting - Samsung Galaxy S7 Edge Questions and Answers

After successfully installing the official Oreo Update for my Samsung Galaxy s7 edge it suddenly started freezing up randomly and restarting itself, at first I thought it was not a problem, but it got so big I can´t even start my phone anymore, and yes I have tried everything except Odin, reset it manually, wiped the cache, and now I do have a blackscreen with my LED sensor blinking in blue and my touch keys lightning, I have no clue what to do, since my phone doesn´t react on anything anymore, neither the on/off button, won´t let me get into the donwload mode either, anything I can do to fix this? about to despair

Not able to start from factory reset again, get's stuck or reboots constantly

hi...
I'm really desperate, my phone is suddenly dying and I have no idea why, I'll tell you from yesterday what has happened:
- I'm playing a stupid game and suddenly the screen goes black. No led, phone doesn't answer any button, nothing. I hold power button, nothing. Remove battery and put again, nothing. After some attempts phone turns on, but just after starting it reboots or stays frozen.
- I decide to change the rom (I had simpl rom), so I do a full wipe and put CM 12. It seems it works, but when I'm in the settings, at the beggining, I don't even have time to put the wifi, it starts rebooting again and/or not responding.
- Desperated, I install via odin the stock firmware from Sam Mobile. It seems it's gonna work, but when the dialog of "Android is upgrading -- Optimazitating app x of XX" it always gets stucked in a number, randomly. I never get to the 230 apps.
- As a last chance, I try Kies to install factory firmware. The same as before happens, but now it's only 17 the number of apps it tries to optimize.
These last 2 times, of course, I enter recovery from time to time (now the default one) and wipe cache partition.
My phone is agonizing, what the f is happening? Does anybody know what could happen?
Please help...

Verizon Lg g2 stuck in bootloop

So for a few weeks now, my phone has been having bootloop issues. I've been trying to fix it on my own, but no luck so far.
I can get it into download mode. Up until I tried to restore it to its stock version via the User Tool, I could get it to the factory reset options, which led to the options to wipe cache, reboot, etc. However, none of those options worked. When I attempted to reset to factory settings, I got the "dead" green android with the red triangle. Then the screen goes black and starts bootlooping again.
Once in awhile I can manage to turn it on after having it turned off for hours, or even days and it works like normal, except that if I lock it or turn it off it will end up restarting and starting to bootloop again. Which is bad seeing as it drains somewhat fast due to being overheated while having the screen constantly on.
As for my experience trying to use update recovery, it gets to the downloading part then stops and gives me this message "[011.700.147.062.092]??? ??? ? ? ????". I don't even know if I am using the correct stock rom for my phone, since I only know its MEID and model name.
do u resolved this, i have the same problem

S7 Edge crashes and reboots at Samsung logo, hardware or not? [All Stock]

Im so lost with this, im all stock but one day my phone just freezes then bootloop, I would be able to get it work by just leaving it and let it drain itself since it will be boot looping and lock me out completely, like the power button + low volume button would not work even after 10 minutes of holding it, would not boot to download or recovery mode, just the soft touch keys light on and the blue LED.
I reflashed my ROM from sammobile yesterday but did it half-effort, just dirty flashed it but it seemed to reformatted my phone anyway, after reflashing it, everything seemed to work properly for 20 hours and then now im back to this piece of ********* boot looping...
S7 Edge
running the Australia unbranded XSA-G935FXXS1DQG4 from the branded G935FXXS1DQG5,
would flashing de-branded affect this? or this is hardware?, one thing I did that I think was a mistake is that I chose to restore from old device, can apps cause this?
the very first time this happened, I plugged it in to charge then crash and bootloop.
UPDATE:
Things I've tried,
-Booting with NO sim card and SD Card
-Wiping cache and partition then reflashing stock XSA and OPS firmwares
im convinced that this is a hardware issue and will go to Samsung.
mine does this too. crashes then gets into a bootloop at the Samsung logo. I usually try holding the lock and volume down button. I factory reset the phone once but it still keeps happening, this started happening around 4 weeks ago
Guys your Main/Mother-boards are broken.. u need to replace it, or send back to Samsung..
Damn! Crash reboot samsung logo
Damn you say broken mother board...
did this. Press vol down, power button and home key...hmmm... i think...pressed so many combos hard to tell themapart

Bricked my phone by updating Magisk Manager

Yesterday I've received a notification about the new version of Magisk Manager, clicked "install", the installation process has started, there was a warning "Boot partition space insufficient" (it used to be before I guess). The phone went to reboot, but turned off instead (or just screen off?). I holded the power button, but the phone did not turn on, pressed a combo of buttons, the phone turned on and got into endless boot (got stuck on logo). I rebooted it with buttons again and enter into TWRP, charge level was 68%. So decided to Wipe it, but after a few seconds the touch screen stopped responding so I couldn't. Tried twice, the same issue. Decided to reflash the firmware, turned the phone off via Power Off in TWRP, after that the phone stopped turning on (completely!). Does not react at all. Not charging, no leds, no vibro.. completely nothing. Seem to be hard bricked or even dead, don't understand why.
Update: no drops, no heats, no water.
I guess it's dead on flashing Magisk, not Manager, but I am not 100% sure.
but why touch stopped working? it might be a hardware problem and soft is jist a coincidence

Click to expand...
Click to collapse
I really have no clue why. Each time I tried to reboot and enter into TWRP, the touch was working for the first X seconds, 5 maybe... the strange thing is the phone was cold at the time.

S7 Edge crashed - has my phone bricked?

Hello Community!
Hoping you'll be able to help me with this: recently my S7 Edge has been fairly unstable, crashing and restarting itself. Sometimes the reboot would fail, and it would loop restart until successfully launching. Today, however, it has seemingly crashed but the phone has done nothing since - it has not attempted to reboot, and power + vol down, and power + home + vol up aren't doing anything. The screen is black, and there are no LEDs showing. I tried plugging it into a charger, but that didn't give any LEDs either.
How can i get my phone on again? Thanks!
stock or custom? odin or just pc dont recognise it?
