How to do a factory reset after a failed OTA

Hey hey,
I received and tried to install an OTA for my GS7 this morning, but unfortunately it failed (stuck for several hours at 76%).
Now when I restart, the phone stays on the GS7 logo, that's about it. I cannot switch it off (not even when keeping the power button down for >1min), but can force restart (vol down + power) and enter download mode (vol down + home + power). The most annoying part is that I cannot enter the recovery mode (vol up + home + power as far as I know) after a forced restart. I tried to let the battery die, and use the same combo before plugging in the phone, but didn't help.
Any clue without me going to a samsung repair shop (which are closed this weekend).
For info, was running stock M on my Canadian GS7 (Rogers).
Thanks in advance for any tip!

Use the Kies 3 software from samsung. As long as you have your S/N and Model # and can boot into download mode you can get reset and on the newest firmware within 20 minutes

Thanks for info!
So I tried that, but the phone still stays on the Samsung logo after the upload..

Explain in detail your procedure

Sure thing:
- enter download mode on the phone by using volume down + home + power. I have to keep them all at the same time to force the reboot and enter the mode (actually restarts twice most of the times before it works). Once the screen is there, accept using volume up.
- Installed latest Smart Switch, verified it's latest.
- connect phone (nothing detected here, even when outside of download mode)
- went to 'emergency software recovery and initialization'
- again, device doesn't get listed here (even when outside of download mode)
- select device initialization, entered model name and S/N
- started the intialization procedure, which downloaded successfully and updated the phone successfully (so it reads). Phone did show progress bar during the update.
- phone rebooted by itself, and back to square one, on a stuck GS7 logo.

Do you have samsung usb drivers installed?

I tried on PC earlier today, yup, drivers were installed. Also tried the Smart Switch 'reinstall drivers'. Before this issue, I was able to connect to the phone properly (same USB port etc)
Now on Mac and fresh install, did the Smart Switch 'reinstall drivers' (after two tests of re-initializaton). Didn't change a thing.

Hmm Def strange. I have had many s7 bricks..hard and soft. Aswell as bootloops but I have always been able to fall back on smartswitch. I suggest you to try kies 3 and if that doesnt work..find stock firmware on sammobile and flash using odin. ( risk of ruining you device involve when using odin. )

Thanks for the tips, will try that!

SM-J410F cannot into download mode?

Hello,
I have a problem, today I install the combination file to my SM-J410F Samsung device but it not work I get %80 and failed and write something (like custom binary fused ) but after that I want to download another Stock firmware but I noticed that it cannot into download mode and when I Press Vol up + power it only show the Samsung logo and turn off, I try many times but it's something.....
I also use jig USB to force the device to download mode but it doesn't work.
Please help me it's very important to me. I Appropriate your bits of help.

Hi,
I have J415 in hand and I believe you can follow these steps:
1. turn off the phone
2. hold vol up+ vol down and connect usb
you should be in download mode now.

I tried many times but it doesn't work.

Recovery
Plz i want link to twrp (recovery) of samsung j4 core (SM-J410f/ds)

I also have a this issue. Power & vol+ & vol- plug in USB, Samsung logo then a blue screen, possibly with an exclamation mark, but only for a split second. The reboots and does the same continuously. I was on android pie uk and tried to flash twrp, failed 3 times. Tried to reflash 8.1 which ended in a fail and now it won't boot, won't boot recovery and won't go into download mode. Does this mean a flat battery? Should I leave it on charge with no sign it's charging? Hold the 3 buttons on reboot for 5/10 minutes?
As it stands now, it's not bricked but I can't do anything with it.

I solved it by holding all 3 buttons and plugging into USB, it did the whole rebooting thing as usual but I kept the buttons held for about 15/20 reboots and then it FINALLY went into download and I could flash stock rom. If important or not, I'd left it charging all night but showed no sign of life whilst it 'charged'

have same problem same it is kind of security to avoid writing Combination

Weird Bootloop (not actually a bootloop)

Phone: J4+ (SM-J415F)
I wanted flash the stock ROM via Odin on pc and something went wrong (i don't know what) and now the phone shows "An error has occured while updating the device software. Use the emergency function in the Smart Switch PC software." I tried to go in the download mode but the phone "restarts" every 2 seconds when i connect it to the pc or the charger.The recovery didn't work either.
Note: The phone doesn't start even if it is not connected to the PC or to a charger.

I'm also stuck in this weird .non. bootloop

Hey, I had this problem before. The Battery maybe depleted during flashing. You have to find a way to charge it.
Try to boot into Odin warning screen or the IMEI screen, it's where the device won't reboot while your connected to a charger, then give it some time to charge until you have enough time to flash your stock ROM.
Its what I did xd, just watch out for overheating. Using a GN variant.

I solved it by holding all 3 buttons and plugging into USB, it did the whole rebooting thing as usual but I kept the buttons held for about 15/20 reboots and then it FINALLY went into download and I could flash stock rom.

Something to Try!
The issue seems to be with the HOME CSC is corrupted on the latest version - Probably something by Samsung to outdo the Combo files being produced.
PLUG-IN THE PHONE to PC (NOT WALL), Press and hold POWER + VOL UP + VOL DOWN to BOOT the phone to the ODIN message screen (with the warning), not the Download Screen itself > in this Screen release all the buttons at the same time, if you do this right you should still be on that same screen. Then simply press the POWER once. This should show a Barcode IMEI Serial, etc (Then leave for 5-15 mins on USB Charge then quickly swap with a wall charger).
Then leave it to charge for normally phone charging time. Later PUT INTO ODIN MODE and retry.
I have done this 3 times on this device to make sure this is the correct way.
You might get away booting it to ODIN and trying to swap the power but unsure about that.
After this Go to GOOGLE Search on your laptop/pc > search for SAMFIRM > Put in the model and Download the Combination for J415FXXU5ASK1 and then in SAMFIRM software click Download ROM > Tick the Binary Nature box and then Flash the Combination file in the AP button of ODIN then the on that ROM go to Orange Calculator (IME) type in *#0808# on the next screen select the option with ADB and RM & DMT (normally the bottom) then select PDA on the next and then SAVE and RESET then flash the SAMSUNG ROM with the CSC, not the HOME!<< Just a NOTE!

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 - Phone Stuck On Bootloop even after factory reset flash with Odin

Hello XDA,
I have a Samsung S10e - (SM-G970W) from Rogers Canada.
Just this past weekend as I was using it, it just froze. None of the buttons worked. I pressed on the Power Key until the phone restarted. However it just loads to the "SAMSUNG Galaxy S10e - Secured by Knox Powered by Andriod" screen and keeps bootlooping every 10 seconds back to the same screen.
I've tried to get into recovery mode (holding Volume UP, Bixby and then Power) but it takes me to a screen which says Watchdog Reset (CPU Hang) with no options for cache wipe or factory reset.
I've also downloaded Odin and the latest firmware version for this phone with Rogers and did a successful firmware flash using Download Mode (Volume Down + Bixby), however after the flash it just goes back into the same bootloop. I've tried flashing multiple times with both the Home_CSC and the other CSC file but both gave the same results.
What else can I do to try and recover this phone?
TIA

The latest firmware may be a problem. You have to use exactly the correct firmware that you had when you put the other OS in it.
It is also possible that you installed the wrong OS. I have the official LineageOS 19.1 which is only for SM-G970F/DS and you have SM-G970W.
