I tried flashing the latest firmware with Oden and it failed, when I disconnected the phone and tried to put it back into download mode it comes up with 2 lines of small text in top left of screen then screen goes blank for a few seconeds then comes up with a list of stuff in blue red and green text with a little android in the middle of the screen with Kernal Panic
Upload Mode to the right of the andriod.
I can not turn the note 9 off, or figure out how to get back into recovery mode or download mode now. and the battery was nearly full when this happened , when the screen goes blank again after a few minutes the led flashes, if I press any of the volume keys or the power button the screen comes back on for a few minutes and while the screen is displaying the message the LED doesnt blink, then two minutes or so the screen times out and LED blinks again.
if I hold the btton down to try and go into recovery mode it reboots after about 10 seconds, shows the normal Samsung boot screen then displays the 2 lines of text at the same time which are in pink, then goes to the error screen I mention above
PLEASE HELP
Is going to take forever for this battery to drain and the unit shut off so I can try to boot into recovery or download mode...
HUGE thanks in advance
Hi! I got this problem too!
I was following guideline in this thread https://forum.xda-developers.com/galaxy-note-9/how-to/guide-change-note-9-csc-easy-guide-t3879473
I was following the procedure, but in very last step while flashing new firmware something happened to ODIN, it failed to flash it. I tried to restart the phone, but it entered KERNEL PANIC UPLOAD MODE. I was trying to get of this, but I was only able to enter recovery mode which didn't work properly either. It was indefinitely looping between installing update screen and other screen with error messages.
If I try to Volume down power for some time, I get POWER RESET OR UNKNOWN UPLOAD MODE.
So, no way out to get into download mode again.
Hi ckhaustralia, did you end up getting some help or an answer about the kernel panic mode issue with uour Note 9 problem you listed above? I have the same exact issue, except the reason why the firmware flash failed in my scenario was due to the charging port which I believe had a faulty sensor because I got a message half way through the flash indicating there "moisture" in the port. Now no matter what I have tried, I cannot boot into download mode to try and fix it. I think the only possible way would be to use something like a ZX3 box but it would be great to hear from someone knowledgeable within XDA?

i've tried to flash my tab using odin and overcome stock safe (first step on their guide). everything went ok in odin, got a green success message. but now, my tab won't turn on or do anything at all. the only response I get is after pressing the turn-on button and then the screen sort of lights up but nothing else.
Have you tried reentering download mode and flash again?
Maybe first time you did something wrong and now have to reflash a stock rom. See "How to unbrick" threads for details
hey
I can't get it into download mode at all. just the backlit screen thing

Try getting into recovery, DO wipe/factory reset, clear cache, reboot... (search how to do it, can tell you, but better U search and find out)
can't do that either. I tried power button + vol up / down combo, but all i get is a backlit screen that turns off the second i release the power button
edit: not sure if its a regular brick, but what happens is this: I press the power button for about 3 seconds, the back light goes on but that's it. if i leave the button the light goes off
Does your PC recognize the Tab in that condition, if yes, connect thru Odin and flash again or try flashing overcome kernel atleast..
nope i've tried to connect it using USB but got no connection
Is your Tab fully charged ?? Try to charge it for a couple of hours and if it turns on, enter the download mode and try again. But please make sure to charge the tab.....just in case.
Good luck
yes, it was fully charged. anyway, i was able to open it up, unplug and replug the battery, but now it does nothing. doesn't light up, doesn't respond to charging or connecting to PC
Yesterday I attempted to flash back to stock with ODIN, but after the program said the operation was successfully completed I was left with a problem.
Now, whenever I attempt to turn on the device it hangs at the AT&T logo for about 10 seconds, the screen goes black, and this repeats indefinitely. And whenever I plug the device into any outlet there is the loading screen before it shows how much battery you have, but before it shows the green bar in the battery the screen goes black, and also repeats indefinitely.
I've tried all of the button combinations but cannot seem to get into download mode or even recovery mode.
There was one time where the device booted up, after about an hour of the AT&T logo flashing, but right after the phone booted up it shut down because it died.
Is there anyway I can get into download mode from this state?
You have a late build phone, you flashed Odin one click to 2.1, later builds phones just bootloop with 2.1, and those bootloaders trend to break the button combos.
You'll need a jig to force download mode.
there is a sticky at the top of the dev section with stock packages, I'd suggest grabbing a gingerbread packages with bootloaders, so your phone will boot up AND it'll fix your button combos.
If anyone wants to know, I was able to fix it quite easily, it just took a lot of patience and without a jig.
I first charged the phone for about 4 hours.
Then I turned the device on and let the AT&T logo flash until eventually the device turned on.
Since I was on 2.1 I was able to use the oneclick root application to root my phone. Amazingly it actually went into recovery and I was able to apply the update.zip.
Next I rebooted the phone and waited until it finally turned on again, from here I downloaded a command line application and was able to use that to force the device into download mode.
Finally, I used Heimdall oneclick and my phone was back to normal.
Hello,
this is my first post on here and I am sorry for it being a "Help me" one.
So yesterday I found my S4 Active again and I remembered it having problems booting up and being stuck in a boot loop. So I powered it on and it worked fine (exept for the lower halve of the touch screen not working, but I think that's another Problem). So I took out the battery. A couple of hours later I tried turning it on again, but this time I had the same Boot loop. When I insert the battery nothing happens (so no stuck Power Button). If I then press the power button it turns on. After the Samsung Logo it goes black for a while but the Backlight is on. After this it shuts down then turns on again but only for a short Moment (no Samsung Logo visible but it vibrates). Then it turns off again and turns on again and flashes the Samsung logo and so on. If I try to Boot into Recovery mode, sometimes it enters Recovery for a second and then turns off and on again but most of the time it just turns of after the Samsung logo and shows the same behaviour as described above.
I am able to enter Download Mode though. If I go into it and press down (to Abort Download Mode) it goes into Boot loop. If I press volume up I am able to flash through Odin ( I did this to flash the stock Rom 5.0.1 again, but it did not help at all). I also noticed that if I attach the phone via usb to the computer but no battery is inserted, the Backlight flashes every 2 seconds or so.
So does this look like a Hardware defect or is there any hope for me.
Thanks
Hi all, this is sadly my first thread in xda, sadly because two things: for being a help-ask thread and because the reason im posting it:
So i decided to flash the new ASIG firmware to my S10, and I don't know what went wrong because odin flashed all right. when i rebooted my device did the key combo to get into recovery mode but it didn't work. Can't pass from the first boot screen because it keeps rebooting
some info to feed your sugestions:
-i was rooted and running a custom rom (August securitypatch on BeyondRom)
-patched AP file in magisk
-ianmacd TWRP
I have tried to get it into download mode, recovery mode, normal OS, magisk boot.... nothing works it keeps rebooting. I remember the battery was like 60~70 % and have been like 7 hours and keeps rebooting.
Also i have tried to get it to boot in download mode waiting till screen goes black pressing voldown and bixby and catching the right moment to plug the cable in it and stops rebooting but doesn't boot either. If i press power button starts again rebooting and the same happen if i disconnect-reconnect or free-press any of the button combo even for one second...
so i have been tweaking my devices like 3 years and this is the first time i think i screwed up one, i always tought it was not possible (hope don't) but this time i think i made it
Do I? there is no fix?
i'm waiting to the phone gets fully discharged to see if powered off can i get it to boot into download mode and fla**** again
is there another way to get it to go into download mode? like old phones with the usb jig
it is a way to turn it off??
do you know what could be the reason to get in this state?
sorry for too much questions but i had a s7 edge before and i messed with it a lot, one day deactivated oem unlock, flashed wrong custom roms and broke it (software way) a lot of times and i always was able to get into download mode and fix it but this time i can't get it to work
so please help me and thanks for read and try to help (if anybody) lol r.r :crying::crying::crying:
FIXED
i'm happy to have been right, its hard to hard brick a device hehehe just after some minutes after (panic atack) post battery went out of energy pressed key combo comected cable to pc and booted un DM im sorprised because did not lost a byte of data
When the S9-S10 Starts bootlooping and won't go to DWNLD mode or Recovery, Just hold Power + Vol DWN + BIX for 5 seconds, release, repeat for ten seconds, release, Repeat,
After that the "upload mode" should appear. and you can just hold Power+Volume Down until the phone reboots. This time the keys will finally boot you into the desired mode...
Got this phone with black screen and stuck on logo issue.
When I turn it on it shows the first startup SAMSUNG M31S powered by android logo.
And the problem is that it stays like that the whole time. The letters darken a bit when its close to the final boot up of the system which is normal but it should show SAMSUNG animation not this screen whole time.
The screen stays frozen like that. When I press the power button the screen turns off and it doesn't come back when I press the power button again. I have to force restart it by power + vol down or just turning it off the normal way by touching turn off on the screen but of course the screen is always black until I power it on again from powered off state. When its plugged into the charger(powered off) it shows that its charging just fine.
The touch works. I hear things when I plug it in. I turned on talkback and when I touch a part of the screen it tells me what's happening but the screen is black the whole time.
Download mode works. KG state is Prenormal I have no idea why, its on stock rom. I flashed correct stock didn't help
Recovery also works. I noticed that when I clear cache or wipe data while it does wipe just fine it also shows this message before the wipe "pdp no scenario"
In the recovery logs I noticed this error as well unable to set property ro.boot time.init.mount.cache so that might be a clue.
Can someone help me with this one? Its on android 11. I can't flash combination file because of the error "please get approval to use factory binary(PIT) "and when I give it PIT file it says the same but at the end its (bootloader) instead ( tried patched odin same thing unless there exist a way to bypass that security.
Thanks!
EDIT2:Added one more image(recovery logs error message)
I was able to unlock it even though its black screen. Will OEM unlock allow me to flash factory binary?
EDIT: I checked OEM option and long pressed in download mode. The phone's screen is now frozen on the "this device has unlocked bootloader...." screen. It boots up just fine but it stays like that until I press the lock screen and it doesn't come up again..
EDIT2: I tried combination firmware it didn't want to flash same please get approval message...
EDIT3: I was able to install twrp. What now? I can see some green color does this indicate display damage? I also noticed this greenish tint on the stock recovery too but in download mode and at the first startup logo no green is present. Why would the display work on recovery and download mode and bootloader is unlocked on this device screen but not work past that????

I've uploaded a YouTube video. I replaced logo.jpg from param.bin with my yellow image to test the colors and as you can see it shows some green, same green as in twrp so ye its the display most likely.
EDIT:
After flashing the PrishKernel the screen is stuck but after sleep I can wake up the screen and at the bottom where the navigation buttons are there is some noise type of image the rest of the screen is black. And its responsive if I press power button the bottom part turns on and off.
Brother you solved the problem??
