[Q] SGH-1897 won't boot, can't get to download mode

Recently my SGH-1897 stopped booting. It would go to the clockwork mod screen. From there, I tried to flash a new rom, but it never worked. First it told me I had the wrong rom for the phone I was using, so I downloaded a different one that said it would work for 1897, but it would fail during the flash. Now, it won't boot at all. It goes to the 'at&t World Phone' screen and stays there. I've tried Vol +, Vol- and Power together, but no change. Help?

What did you try to flash? Also, what was installed on the phone before you tried flashing it?
If you can get it in download mode, you can use Odin to flash stock ROM (without bootloaders if you were on GB and up). That should get you back up and running.
If the button combos don't get you in download mode, you'll have to make or buy a jig.

[Q] Softbricked my phone... need help!

Hi,
So I try to flash my phone with Odin, but it seems I made a mistake. It's a long story... When I go back to stock rom from custom, I use Odin and my phone goes to a bootloop. Then I try to reflash stock rom with Odin again and I have the same problem every time. I like to clear cache/user but when my phone goes to recovery mode I can't navigate with hardware buttons (not hardware issue) just the power button works so I can't do nothing here. Ok here start a strange part (for me) bc. download mode it's not accessible with key combination just from command line and when I get download mode I try to flash twrp recovey with Odin but the result is sofbrick. My phone not recognized by Odin and adb commands not working anymore. I can't access recovery or download mode. My phone stay on logo and nothing happen.
Thank You for any solution!

Can't boot to flash mode or recovery mode.

I really need help.
I've got my phone bricked and I can't even boot to flash mode or to recovery mode.
The last thing I've done is boot to twrp and clear data because I am going to change rom. But there is a certain error that pops up. and forgot what was it. After that, I try to flash the rom. But the same error pops up. If I remember correctly. e:ex4ts is not found? Something like that? And now. When I turn on my phone. The xperia logo still pops up. Then after that its only black screen. I tried going to recovery (power + Vol up + vol down) and also tried flash mode but nothing really happens. Its like not being detected. And when I try to charge it. The xperia logo pops up and black screen appears. The charging icon/animation is not popping up. Is there anyway to fix this? Please help. Any help would be much appreciated. Thank you.

Your phone is now bricked and won't boot into recovery.You need to flash stock rom via flashtool to recover your phone.Is that your phone's bootloader Lock?Unable to boot into recovery always happen in locked bootloader phone.

Use Flashtool to flash stock rom. But be careful to connect phone only when prompted. It should boot after that, then you can root phone again and try to install recovery again.

I have unlocked bootloader already. I think there is something wrong with the phone. I can't boot to flash mode and recovery mode. The screen continues to go black light. I've tried for more than 20 times already. But still. I can't go to flash mode. Can I go to flash mode by only connecting my phone to my pc?

use recovery img to flash via flashtool.you'll get your recovery back

Thank you so much for answering my query. I figured it out before reading this. Yes, I forgot how to use flashtool. I forgot how to boot into flash mode. I used the method in Samsung devices (All buttons must be pressed) which technically my mistake. Thanks again.

G973F Stuck on Boot Screen After Failed BeyondROM Install and TWRP 3.4.0-3 Flash

I believe i've royally screwed up and i want to know if there's anything I can do to save my phone.
I downloaded the latest BeyondROM from here after being on a previous version for about a year (not sure which one I was on):
https://forum.xda-developers.com/ga...evelopment-exynos/rom-beyondrom-v6-0-t4017921
I flashed the zip file through TWRP and only after flashing did I realize that I was on TWRP 3.3.1-11 and not 3.4.0-3, which I'm guessing is why my phone is now stuck on the boot logo when I boot it. I went back into TWRP and cleared the Dalvik & standard cache again after this but no dice.
But it gets worse. I then tried to upgrade to 3.4.0-3 by flashing it from TWRP 3.3.1-11 using the recovery partition, hoping to reflash the firmware after doing so.
After doing this and my phone rebooting, not only am I stuck on the boot screen, but now I can no longer enter recovery mode either by holding Bixby + Vol Up + Power. My phone isn't recognized by my PC or Odin now either.
Is my phone completely bricked, or is there a way to salvage this mess i've made?
Could really use some help.
Thanks guys.

If you can go to download mode, try re-flashing the stock Samsung firmware via Odin.

Thanks for the suggestion, however that's my primary issue. I can't get to download mode (which really should be recovery mode since I have TWRP).
Do you think it could be an issue with me rebooting to recovery mode after upgrading TWRP using TWRP itself? Maybe my phone needs to be hard powered off once to access TWRP again?
And since I have that failed ROM install, the only way to power off the phone would be to wait for the battery to drain.

Power+volume down+Brixby goes right into download mode bypassing the recovery

My phone just keeps restarting when Power + vol down are held. Looks like draining the battery didn't help either. I'm stuck on the boot screen even when plugged in with 0% battery. When I remove the USB Cable and hold Vol down + Power, the phone seems to turn off because there's no battery, but immediately after plugging in a power cable, the phone automatically turns on by itself again.

You can try this, but best not to flash anything without charging battery first. You can charge while phone is off:

Could not do normal boot. Invalid KERNEL LENGTH.

This message I get when I try to power up my Note 9 N960F/DS.
I got it this way: Been running the same ROM for 2 years. Time to upgrade. Upgraded TWRP via the app. After downloading the ROM image to SD card, I tapped an app called Reboot, with the Recovery option. I suspect this app is from some old installation, and ended up on this unit via data restore. Now all I get is this message on a black screen. No logo, nothing. Message flashes once. If I plug into PC, message flashes repeatedly. Cannot boot to recovery using Vol-+Pwr, Vol++Pwr ineffective.
I suspect I bricked the phone, but I seem to remember once breaking out of this 2 years back, I think. Any ideas, clues, anything?

Try this, power off phone. Press volume up and bixby button and while pressing buttons insert data cable, phone should go to downlaod mode. OPen odin and flash stock firmware.

OK, tried it, display showed the same message until I released the buttons, then flashed the message every 4 seconds until disconnected.

OK, got it into download mode, reflashed twrp, now it's in a boot loop. Will continue working this.

It took a few tries, but I not only got everything working, I restored my data backup and upgraded to Android 10. Thanks all!
