My Samsung galaxy tab s8 ultra is stuck in a boot loop. I need to hard factory reset but it doesn't seem like power button + volume up the bootloader/download screen. Is there any other way to hard factory reset this?
Try plugging it into your computer and then holding down volume up and volume down at the same time. That can get it into download mode. You may need to try holding those buttons at different times. But try to do it right when the screen turns black at the next boot loop and then continue holding them down until it shows download mode.
If it doesn't work after a few tries, then try unplugging it from the computer and plugging it in again and repeat.
Mine was stuck in a Samsung Dex boot loop. I got out of it by pressing power + volume down, entering safe mode, and then doing the hard reset. Also if you are able to turn it off completely then hold both volume buttons while you plug it in you should get into Odin mode

Yes! That's the exact loop I'm in. I tried both power + volume up and power + volume down and it would just keep booting up normally then load Dec and reboot.
Volume up and down plugged in worked. Thanks!

I was upgrading to Cog 9.1 using 2e recovery and I think my captivate is now bricked. It does not display anything (only black screen). Even after connecting to USB I do not see the battery charging symbol. Is there anyway out of this mode?
I have tried all the different key combos to try to get into download mode. I could always get into download mode earlier using down button + power button combo.
Any pointer will be very helpful.
How did you flash, and when did you realize there was an issue
Captivate
Cog 2.2
I flashed using ROM manager and I realised the issue after the screen remained black for around 30 mins.

the volume buttons and power combo are used to put it in recovery. Mine got stuck on the at&t logo. I pulled the battery after about 40 minutes, turned it on into recovery, wiped my data, rebooted, then worked flawlessly. My advice -> pull battery, put it back in, hold volume buttons, then connect the usb while continuing to hold up/down volume buttons, this should get you into download mode.

This sounds like i9000 rom button combo. Won't work with COG. For recovery hold both volume buttons and hold power button in. When at&t logo shows up, wait about a second and release the power button but continue to hold the vol. buttons. Should get you there.
For download, hold volume buttons down and plug in usb. Should put ya right there.
If you have a cappy that has the no buttons bug, you're pretty much hosed.
Designgears has a thread in the development section about the 3 button issue, with a mod that fixes it. Give it a read.
If you had usb debugging enabled and the computer sees the phone, you should be able to use adb to reboot recovery or download too.
I have an i9000 international, and I recently (attempted) to flash Darky's Rom 10 RC6, after flashing it in Odin, my phone started booting. All is fine until after 'S' logo screen. I've tried to get it into download mode frantically, but nothing is working. The 3 button press, not working. I've tried other methods, like removing the battery and plugging it into your computer, then volume buttons, but nothing...
Please help
Are you holding the Vol down + Home + Power buttons together long enough ?
Yeah, I've tried holding them down until the splash screen goes away. Just regularly boots, and then stop holding down power button when the splash screen is up. No luck. I think I might have to just jig it.
It can be tricky, in mine you first have to press home, then on+down, but in order that on goes before down...all other combinations at least in my I9000 won't work, and if it fails, remove the battery put back and try again.

You shouldn't even be seeing the splash screen.
What works for me everytime, is doing it in this order:
Press & hold down the vol-down button & home button, then (while still holding down those 2 buttons), press & hold the power button. You should be in Download mode in like 1 to 2 second. When you see the Download mode, let go of all 3 buttons.
Dear all,
I was on beyond 5.3 with twrp 3.3.1.7 and I wanted to update everything. Magisk, root etc was working fine.
I downloaded the patched twrp file from the beyond telegram chat and flashed it as image into the recovery partition.
The installation was finished in 2 seconds, but stupid me chose to power off instead of rebooting the recovery.
So I tried to enter recovery using the button combo but nothing happened and I was stuck with the samsung logo.
The current status is that my phone only shows the samsung logo.
Holding the power button for a minute doesn't do anything.
Pressing the button combo for recovery mode doesn't do anything.
Pressing the button combo for dl mode makes the phone reboot. It vibrates for a sec, then the samsung logo shows again.
If I keep pressing all 3 buttons the phone keeps on rebooting and vibrating each time, but dl mode never appears. If I let go of the power button the logo stays and again, nothing happens.
So basically I can't enter dl mode nor reboot.
Should I let it run dry and try again or just throw out of the window immediately? :crying:
I let the battery drain over night. Phone was finally off.
So when I plug it in, the Samsung Logo appears and doesn't change. It just stays like that forever until the battery drains.
Pressing the power button doesn't do anything, no matter how long. It doesn't reboot nor does the logo disappear.
Pressing vol+, bixby and power again does nothing.
Vol-, bixby and power makes the phone reboot. The screen turns black, the phone vibrates shortly, the logo reappears. If I keep pressing the buttons the phone reboots again, and again, and again, mever reaching download mode.
If I let go of the power button and keep pressing vol- and bixby the phone stays black and won't even show the logo. Nothing happens. If I let go of either of the two buttons the logo appears again.
It won't boot, won't go into recovery or go into dl mode.
I'm doing all this while it's plugged into the usb port of my pc, and it doesn't get recognized. Samsung 300k tool doesn't recognize it either.
Now I know the meaning of "bricked" lmao.
Does anyone know how to possibly fix this?
Pressing only the power button for a minute literally does nothing. Like hell, how is that even possible?
You can try this to go to download mode:
Vol down + bixby + usb cable connect to PC
It's advisable to charge battery first before flashing firmware.

I tried that for like a thousand times already but now it chose to magically work somehow.
I think I peed myself a little when that ugly turquoise screen appeared and I screamed from sheer happyness.
THANK you!!!
The problem that doesn't stop giving lmao.
Got into DL mode, got odin to start, but after like 10 seconds my phone dies and odin fails.
Now I cant get into DL mode, but rather only the "an error occurred while updating the device software. use the emergency recovery function in the smart switch pc software."
Could it be the battery that simply dies?

Yes most probably a discharged battery. Hopefully you can go to DL mode again after charging your phone.
hello,
I've and S10e and because an important app to me I need to go back to android 9 where it works.
I've read a lot info about downgrade, but no one says ROOT/UNBRICK.
Can someone inform if there is a way of downgrade without ROOT (maintaining the warranty).
thanks in advance
P.S.: Maybe too naive question, sorry for that
Hello,
I've (soft) brick my S10+(TWRP flash and reboot by mistake)
I only see black screen, when I try to boot in download or recovery mode
So I can't see, in which state the phone is
If I plug in in charger, I don't see the charging icon, so I think, the phone isn't really off
What I try:
vol- + bixby + plug usb into notebook: noting happens
press power: nothing
vol - and power; I get the warnscreens, after that, the screen is black again. If I tap on the bottom or middle of the screen, it vibrates
vol+ +power: nothing
So. I hope it is only soft bricked an somebody can help
Thanks

Is there a button combi for force shut off(not reboot)?
there is. I believe it's vol - plus power button for 7 seconds.
Try doing that then holding just the vol - and plus the usb cable. Can't remember is fastboot is supposed to show anything.
Samsung phones are a nightmare for tinkerers.
Same I have a s10+ and I used Hijacker tool to soft brick because it got stuck on update mode, apparently it didn’t update fully. then used Odin to install new update. Connect your phone to pc and press power and vol down after the vibration quickly press vol up+ power+ bixby. Then you can factory reset. but idk why mine still doesn’t turn on even after factory and cache reset

I am trying to get into recovery mode but my phone just doesn't seem to care at all. I tried all possible combinations and timings, it's just booting normal. Is this some security thing? How can I get into recovery mode?
Fully power off the phone
Once the phone is full shut off, wait 15 seconds
Hold down the volume up button first
Continue holding the volume button down and power the phone on, continue holding the key combination until the Samsung logo appears.
You should now be in recovery mode and can navigate using the volume keys up and down, power button to confirm.
You have got it plugged in to a PC via USB right? You can't do it now unless it is plugged in to a PC with USB

Thanks guys, the USB cable did the trick. But why is that? What an unusual way...
Just to be annoying!
