When I plug it into my PC I get an error message on screen "an error has occurred while updating the device software" and the screen flashes white every 2 seconds.
When unplugged and off I can't turn it on so I can't enter download mode. It also doesn't respond when it's plugged in with the error message on screen.
It was a family friend's but they wouldn't have attempted to root or do anything advanced, they said it just 'happened' one day.

Plug in the mains charger.
Hold Volume Down + Home + Power.
Do not release until download mode appears.

Can't get to download mode after "error occurred while updating device SW". s7 edge
While trying to upgrade my Claro galaxy s7 edge from android 6.0 to 7.0 using Smart Switch my phone crashed and the software got corrupted. (couldn't do it through manual/automatic update).
Now i'm stuck on the Window : "An error has occurred while updating the device software. Use the emergency recovery function in the Smart Switch PC software". I tried both the emergency Software Recovery and Device Initialization but both failed with error "failed to run firmware upgrade unknown error occurred". Tried it in different computer, restarting both the devices, reinstalling device driver. Nth worked.
Finally i searched forums and tried to flash custom rom using ODIN. Thing is while downloading the ROM my phone went to Download mode when i pressed "Volume up" + Power + Home button but now the combination just does nothing and i'm stuck on the "An error has occured window". I tried 300k tool and also Both volume + power + slide in usb cable combo but nth happened. I tried to install custom rom through ODIN while in this window but ti fails after 2 mins too.
Also Pressing Volume down Power and home (recovery mode) brings me to this same window again and again. Just waiting for the battery to die and start anew.
Just 4 days with my phone. Any help to solve these problem are appreciated.
Did you try already vol down + home + power and as soon as the screen goes blank switch to vol up + home + power to get in recovery mode?
Stuck on error screen; no download mode

I am having the same issue after trying to flash updated ROM on my S8 via Odin. Process got to the end and said 'FAIL'. Following the reboot, I was stuck on the 'An error has occurred...' screen and every attempt to enter Download mode or recovery mode (By quickly switching to the volume up button in between reboots, as you stated) has failed. Smart Switch is not recognising my device either despite all the correct Samsung USB drivers being installed. Any ideas anyone?
Apologies for posting here on S7 forum but the problem is identical.
Did you ever fix this? I have the same problem now

Hi! i know this is an old thread but i know how to fix it. You can flash with odin while you n the error screen. My phone (almost) died when i saw my kg state is prenormal and tried to flash magisk firmware but then... m phone showed up the error and then figured this out you can flash with odin when you are on the error screen.(sorry for bad english)

Hello. I was in the boot menu whilst using my Samsung Galaxy S8 (I was just looking around) and entered the bootloader.
I see a blue screen with a down arrow which says "Downloading... Do not turn off target"
The phone will not receive any input and I cannot turn it off.
I have tried to use fastboot reboot to reboot the device, but the device isn't being detected (In the device manager it says "Unknown USB Device (Device Descriptor Failed)").
I'm sure if the device dies it will boot properly, however I would not like to wait that long. Any help would be helpful, thanks.
just long press the power button (for 15 seconds or so). It will restart.
I have tried this already, a restart has not happened. To make sure, I tried it again and timed it for 25 seconds, the device did not power down.
Try holding both power and volume down.
That worked, thanks.
I've never had a device which required that combination. Perhaps I should have tried it first before posting, regardless, you have been a big help.
Hi,
I have a nexus 4 that is stuck on opening animation and won't go to fastboot\recovery.
(a weight fell on it a long time ago. Worked for the next 3 days then died.)
Situation now is that it is stuck on the opening animation (lollipop) when turned on.
When trying to go to fastboot using volume up+down+power I get a blinking red light (volume up\down only with power button only resets the device or turns it off.)
Computer recognizes the device and I can see it in ADB devices while stuck on opening animation, but it says "unauthorized" so I can't use "adb reboot recovery" command.
Trying to press up+down+power while connected to computer gives solid red light and repetitive "device connected" sound from the computer every 1 sec.
Phone was never rooted or flashed in any way.
Any idea what I can do? I don't mind restoring factory image or factory reset.
Thanks to anyone who tries to help in advance
I tried flashing the stock firmware via ODIN but the process failed and now my tablet is dead and not responding to power button + vol up/down, nothing happens.
When I hook up the tablet to the Samsung charger that can with it or my PC, the tablet boots into download mode and shows the "an error occurred while updating the device software" message and then starts after about 1 sec. It's been charging all night, so the battery should be 100%.
If I hold the vol up+down is shows the long press to unlock the bootloader for about 1sec then reboots.
Any help to force my tablet to stay on and a way to fix my issue ?
same thing happens with mine (after trying to flash firmware via odin)
reboots over and over without letting you stay in download mode
i have mine in edl mode
It maybe in a black screen of death. Either vol up or down and power for at least 10 seconds. I had this happen to me once.

how do we boot the tablet into EDL mode? shouldn't we be able to unbrick the phone if we're in EDL mode?
IT says an Error Has occured while updating the device sofatware and I can't get out of it. I hold power and vol down button and just quick reboots back into the same screen even when conntected to laptop. I also move my finger from vol down to vol up while the screen is black for about a second and nope still go back to the same screen.
Try it
