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)

Unplug usb from the phone.
Press the power and volume up and volume down and home buttons at the same
time.
As soon as you feel vibration let go of the volume down button while pressing
the volume up, power and home button until you see the samsung logo, then
let go of all the buttons and it should boot into recovery mode.
If it does not boot to recovery mode after doing the above steps 3-4 times
you will need to press volume down and power button until the phone
goes into "download mode".
Once in download mode you will need to re-flash the stock samsung
firmware again.
But this time make sure you flash the correct official version and model#
for your phone's model.
Good luck, have a great day!

Hi Guys!
I'm new to XDA developers, but I've been following this forum for many years.
I would like to resurrect my old phone, a Samsung Galaxy S4 Value Edition (GT-I9515), witch is most likely bricked.
About one year ago, the device started to randomly reboot, until it no longer powered on (It was NOT rooted or modded).
Recovery also did not work, so I decided to flash the stock firmware with Odin. The flash failed, so i decided to follow a (really stupid ) guide that said that to solve it was necessary to flash a PIT file of the Samsung GT-I9505, so I tried it.
Since then, I'm not able to boot the phone anymore.
What can I do with the phone now? What have I tried? I'll try to be as clear as possible:
Recovery mode:
I can boot into recovery only by pressing VOL UP + POWER with phone connected to charger, and then inserting battery keeping pressed the buttons, but when I try to boot into Recovery Mode, 3 different things can happen:
It does not power on
It vibrates, then reboot and freeze in Samsung GT-I9515 logo
It vibrates randomly and then open successfully the stock recovery
Download mode:
I can boot into download only by pressing VOL DOWN + POWER with phone connected to charger, and then inserting battery keeping pressed the buttons, but when I try to boot into Download Mode, it seems that the screen freeze at a certain point while loading the recovery mode warning (this warning loads slowly, like a slide from top to bottom). The device rarely fully load the warning, and when it does, when I press the VOL UP key to confirm entering download mode (sometimes it does not respond to VOL UP click for confirmation and i must reboot) Odin is able to find the device but during a flash the Odin log stop at Setup Connection, so the device is not responding.
Normal boot:
Yesterday, after hundreds of attempts, I was able to start the phone normally (I don't know how) , it asked for the initial configuration and language, but when I turned it off, the problem reappeared and I was not able to boot it normally. In most cases, the device freezes in Samsung GT-I9515 logo, it continues to restart or simply does not vibrate or power on.
When charging, I don't see anything such as the charging battery icon or the LED.
I realize that I was wrong to flash that PIT file, but is there anything I can do to make this device work properly?
Thank you in advance for your cooperation.
Noone?
Hello friends
As many of m30s user reporting random freezing while using and auto reboot on itself or sometime not even turns on by pressing and holding volume down and power key.
I too was mad at this hardware problem
I tried all possible ways like flashing old firmware or using aosp ,lineage os,but nothing was successful
Finally I tried one last method which was randomly tried
But that step unknowingly successful.
I have tested it many times without any previous behaviour.
Please check this link
hopefully it may work for you also.
i there. After (an attempt) to unlock the bootloader of my m30s and installing TWRP Recovery (TWRP_A50_Magisk_Prepatched) i find myself in an orange bootstate. I can't get it into recovery, download or fastboot mode. It seems like a full brick. I can't even power off the device. Only Volume up, Volume down and Power button let's the device reboot but then the same boot problems appear. Is there anything i can do to recover my phone?
Text of first screen when booting up:
"The phone's bootloader is unlocked and it's software integrity can't be verified. Andy data on this phone may be vulnerable to attackers. Don't store any important or sensitive information on this phone". Press power key to continue"
Text of second screen when booting up:
"The phone is not running Samsung's official software. You may have problems with features or security and you won't be able to install software updates"
Any ideas!?
Press and hold volume up and down and Connect to computer with drivers installed.
Flash stock rom using odin tool.
