[Completed] Can't boot into download mode Samsung Galaxy S7 - XDA Assist

Ok, I bought a galaxy s7 from my friend, because he was getting a new phone, but I discovered that wifi wasn't working at all, so I thought it had to do something with the firmware and I decided to flash the rom with odin, with a newer version of the firmware.
This is where all my problems started, when I restarted my phone for the first time I noticed that the startup/booting animation was some weird ****, not like the usual one (the samsung logo) but was a weird loud animation with the letters of MTK, in that moment what came to my mind was that I just could be a custom rom or just a custom boot animation, so I didn't gave it too much attention, I continued to do what I was gonna do and tried to boot my phone into download mode with the classic normal method , Volum Down+Home+Power, when I tried this apparently It didn't work, I could stay there pressing the buttons for like 5 minutes and nothing would happen, and once I would release them, the phone would turn on and do the weird animation and boot like normal, at this point I was already worried so I proceded to Root my phone with KingRoot and install an app to manually boot my phone into download mode, it didn't worked. After hours of searching for a solution I found about ADB and I did all the steps to boot my phone from there, still nothing, when I typed the "abd reboot download mode" or something like that, the phone would just restart and do the ****ing weird animation again, so I tried booting into recovery mode and when I tried to do it, an android robot would appear laying on the ground with his chest open, and the words "No command". When I would press the home button the phone would react and send me to the recovery mode, normal.
So I'm begging you guys for help, since I don't know what to try now.
It looks like the download mode or maybe the firmware is broken, and I can barely do something without the download mode, pls help.
What I've tried so far:
-Basic 3 buttons method (can't remove battery, it's an s7)
- ADB method
- ADB fastboot method
- Vol Up+Vol Down+Home+Power
- Can't do anything with Odin since I need download mode
- Tried to install twrp recovery mode from ADB but says that It didn't found the file
If someone knows a solution for this please tell me what I can do.

[Completed] Android boot loop - is my device dead?

Hello All,
This is my first post at this forum.
I've come to a point where I'm on the verge of giving up.
A few days ago my Nexus 5 entered a boot loop without me doing anything special with it - it was just in my pocket.
All see is the google logo for a few seconds , then the screen goes down for a few more, and back to the google logo.
I'm able to go into fastboot by hold down the volume down (only) button when this happens, but the boot loop happens when I choose to boot into recovery mode.
My device has an unlocked bootloader.
I have fast boot access and no ADB (ADB wait-for-device doesn't work).
Went over a tutorial from androidforums.com and flashed a completely new image using fastboot.
The entire process worked, but the phone is still at the same state.
I've read that there is and issue with the power button on these devices - so I tried all methods of knocking it against stuff without success.
I've taken it to a lab nearby and the guy there was sure it was the power button. He said he fixed about 50 of these already - after a few hours he called me up and said he had replaced the power button 3 times and he's giving up.
in short , this is the current situation :
1. Device stuck in bootloop - only google logo is seen
2. can boot into fastboot (and have fastboot access from PC) but can't boot into recovery
3. flushing a stock succeeds but won't help
4. power button seems o.k.
I am about to call this a bricked phone and look for a new one but something inside me tells me that this might still be a software issue and can be fixed.
I would be happy to know if there is a way to know what is failing in the boot sequence. or maybe load a debug application on to the device to check the HW. I've yet to find any help in that direction.
I'm a software eng. working in the cellular comm. field, so I'm up for anything that anyone has in mind.
Thanks,
Ran.

Hello, and welcome to XDA!
It does sound like a hardware issue and it could be the power button, except for one thing: wouldn't a held down power button in fastboot cause a shutdown as well? Maybe not, but I thought I'd ask that.
At any rate, better to get an opinion from someone who actually has the deivce. Please create an account (so you post in other forums) and then post in this thread (can copy and paste from here):

Hope this helps, and good luck!

Help with soft brick?

My phone seems to be stuck in download mode. I'm trying to get it to recovery, all attempts result in it going back to download.
I just don't know how to get something else showing on here.
Background: Phone was rooted on Kitkat but I lost the root when I upgraded to Lollipop.
Was trying to root the phone with via the one click (http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951) which seems simple enough. However, my phone would not enter into download mode so I couldn't continue the steps. I found someone with my exact problem right here on XDA (http://forum.xda-developers.com/showpost.php?p=57125760&postcount=9) and in doing what he did, my phone DID enter into download mode, just got stuck in it.
Edit: In pressing Volume Down and Power off and on (press them, release them, press them, release them, etc) an unknown white screen that reads "Factory Data Reset" and a "yes" and "no" has came up. I don't know if I replaced my CWM recovery with this weird thing, in doing what the XDA poster said?? Even if I press "yes", the download mode screen comes back upon restart.
2nd edit: I did get it working. Left the phone connected to the LGMobile Support Tool while I tried the "Upgrade Recovery" again and after a few tries of that it turned on all by itself. Will try rooting again, hopefully succesfully this time

Samsung S7 can't boot into download mode

Ok, I bought a galaxy s7 from my friend, because he was getting a new phone, but I discovered that wifi wasn't working at all, so I thought it had to do something with the firmware and I decided to flash the rom with odin, with a newer version of the firmware.
This is where all my problems started, when I restarted my phone for the first time I noticed that the startup/booting animation was some weird ****, not like the usual one (the samsung logo) but was a weird loud animation with the letters of MTK, in that moment what came to my mind was that I just could be a custom rom or just a custom boot animation, so I didn't gave it too much attention, I continued to do what I was gonna do and tried to boot my phone into download mode with the classic normal method , Volum Down+Home+Power, when I tried this apparently It didn't work, I could stay there pressing the buttons for like 5 minutes and nothing would happen, and once I would release them, the phone would turn on and do the weird animation and boot like normal, at this point I was already worried so I proceded to Root my phone with KingRoot and install an app to manually boot my phone into download mode, it didn't worked.

- Can't do anything with Odin since I need download mode
- Tried to install twrp recovery mode from ADB but says that It didn't found the file
If someone knows a solution for this please tell me what I can do. Sorry for bad english, right now I'm kinda exhausted because I've been trying over and over methods for like about 6+ hours

No idea really but just to be sure. Did you try switching off phone completely and then trying 3 button combo for download mode?
Also post that **** boot animation logo as that might help us figure what you have flashed on phone.

bricked s7 edge HELP!

hello
i fear i may have f##cked my phone and am panicking!
i installed a custom rom and the installation seemed to go well but aftetr when i rebooted it seemed to stay on the loading screen for ever even after multiple reboot attempts. anyway i messed around with it (not remembering what i done) and everytime i boot after it shows the s7 edge text it immediately loads a red screen. i have tried to get into recovery by holding home, power and vol up but again boots to red screen. i can boot into downloading mode by holding home, power, vol down.
so ive done some searching on google and it points to i need to flash stock rom with odin whilst in download mode. i got the stock rom for my model and attempting to flash but after sboot.img it fails. (screenshot attached).
please someone help!

That error means it's the wrong firmware. Flash the stock that was on it before you messed about with custom ROM.
Also please read ALL instructions when flashing custom ROMs, some take 15 minutes on first boot.
UPDATE
the error only happened as i wasnt flashing the very latest stock rom. downloaded from samsung website and now is working fine
phew

Please help! S10e can't enter download mode...

Please help!
Hello! This is a distress call, because I think I brickered my S10e, through my own fault ...
Trying to install the TWRP according to the instructions given in the Hades Rom, I made two unforgivable mistakes, since years of flashing roms ...
1) I took the wrong installation file (I have the G970F/DS, and flash the beyond2lte file, instead of beyond0lte)
2) I omitted to force boot of TWRP just flashed.
Result: I cannot enter download mode as I did before (the phone does not blink), and trying to enter recovery, out of 20 attempts, it only turned on 2 times and does not go beyond the warning screen that the oem is unlocked, and it is not a safe state. I press power to continue as it says, and the screen turns off. Of course it doesn't start normally with the power button either.
I found out recently that been connected to the PC, it is recognized by it, and I even could access to it though the Windows explorer... Ergo, it's not dead, but the screen is in the infamous "black screen of death". Tried the usb jig emulator, by sugestion of denon480, but it didn't work (see screen capture).
Is there a way to force it into download mode, to flash the correct recovery, or eventually an official firmware? The cell phone is immaculate, I can not resign myself to it turns paperweight !!!!!
I put this here, because the problem was in TWRP recovery flashing, I didn't arrived to the Hades ROM installing process, and this way I can reach more people...
I appreciate any help.
Cheers

I don't even think it is possible to brick Samsungs like that. Are you following the right steps to download mode? Ergo,
Step 1 – Turn OFF your Galaxy S10.
Step 2 – Now press and hold the following buttons on your phone together: Volume Down + Bixby Button.
Step 3 – Next, plug in one end of the USB-C cable to a computer and the other end to the phone. As soon as you will connect, your phone will power on.
I have the same problem. I do not know if the OEM unlocking has something to do with that as I can not turn on OEM although it is not missing but it is not active and can not be turned on. I tried all the solution available online but it looks like no one knows what to do even the so called experts know nothing at all and the only things they know is the direct easy way. So disappointed
Same problem here... any solutions?
