Bootloop phone without download or recovery - Galaxy S6 Q&A, Help & Troubleshooting

I tried to install a kernel on my G920I but it crashed on the boot screen with the message "kernel is not seandroid enforcing". The usual procedure to resolve would be to reinstall the original rom, but my device does not go into either download mode or recovery mode. No matter what key combination I use, it always goes back to the boot screen or load screen when I plug the cable into it.
Ps: Before bootloop the phone only went into download mode through JIG, but went into recovery mode normally. What to do?

[Q] unable to enter recovery mode & download mode as well

Hello guys,
I was hard formatting my Alcatel OT 918N from recovery mode. After deleting cache partition and wiping data from recovery mode I restarted my phone but then it went in an infinite boot loop i.e. it starts but right before displaying the home screen it restarts again.
Now I am not able to go in recovery mode too. When I try to go in recovery mode, my phone freezes on android logo. I have tried almost every key combination but my phone doesn't enters download mode, the only mode which comes is factory mode in which there are device testing options.
My device was running on stock ROM but it was rooted.
Please help me out

Stuck on Splash Screen (Cannot Get into TWRP)

I flashed CO15 Bootloader and Modem in ODIN. Reboot went fine. Held down power and tried to reboot into recovery. Stuck on splash screen. I can only get into Fastboot. I installed TWRP through ODIN but still can't get into recovery. Not sure what to do?
Stuck on Samsung Galaxy note 5 Screen
On top of screen in red text: RECOVERY IS NOT SEANDROID ENFORCING
Tried holding Volume up, Power, Home to enter recovery but not working
re-flash coi5, and let it boot all the way out.. at this time (for me) it will bootloop at the tmobile screen. catch the reboot with vol up + home + power, and let whatever happen happen (for me it said no instructions or something after the little green man) then click down to factory reset/wipe data, click that, then let it reboot all the way out to home screen.
THEN flash the stuff yo uwant.
I tried to reflash twrp and the boatloader and the modem but none of that worked. I had to download and extract stock firmware package(over night) because sammobile has very slow download speeds for free users. This morning I flashed package, rebooted into fastboot and flashed Twrp and was finally able to boot into recovery and restore.
Thank you

Do you still have the RECOVERY IS NOT SEANDROID ENFORCING on the boot up screen? Instead of recovery mine says "KERNEL is not seandroid enforcing" and I'm not stuck in a boot loop. And I'm assuming that after you flashed the stock firmware you attempted root, and after root was the message gone?

The "recovery is not seandroid enforcing" message is normal for having a custom recovery installed & should only appear when booting to custom recovery, well for TWRP anyway.
The "kernel is not seandroid enforcing" message will appear for a number of custom kernels on every bootup, at least in my experience. I don't get this message when using arter97's kernels.

Bricked. Can't access fastboor or recovery

Hi guys,
my Mate 9 is stuck at the black screen after the Huawei logo screen with the "Your device is booting now..." text. I can't get into recovery mode or fastboot mode. Is there any way to get out of this situation?
Here is what has happened:
I wanted to root my Mate 9 so I first unlocked the bootloader and flashed the TWRP recovery.
But after flashing the recovery I couldn't get into the recovery. When I pressed the button combination the phone was always stuck at the screen with the "Your device is booting now..." text. But when I booted the phone normally without pressing any button it would boot just fine past the screen.
So I thought I should try to relock and unlock the bootloader and install the recovery again.
When relocking and rebooting the phone it went to the Huawei Updater mode or eRecovery mode, I don't know which one. It wanted to reinstall the firmware or something. But that failed so I thought maybe I should flash the stock recovery so that it can install the stock firmware.
Then I unlocked the bootloader again and the phone reboots automatically and wants to factory reset the system but it gets stuck at the black screen with the "booting now" text.
Now I can't do anything. It doesn't boot normally, can't get into fastboot or recovery mode. Can't do anything, basically.
Is there a way to save it or am I game over now?

Booting to recovery (TWRP) using power + volume up with USB plugged in goes to eRecovery.
Power + volume down is fastboot, regardless if you have USB plugged in.
This mode should always work.
Power + volume up and down goes to the auto update screen.

Wow, I just wanted to say that no combination works but somehow it went into bootloader mode.
I tried the power + vol down or vol down + plug in usb but that didn't work. Now I pressed vol down + power and plugged in and plugged out the usb cable repeatedly. Maybe it worked because the battery was empty, i don't know.
I had a root Huawei and have now managed to have gotten it exchanged and will not be rooting this device for a while. While I miss out on rooted apps the speed and performance of this device for me outweighs having root access.

Can't boot instantly into recovery mode after flashing twrp with odin

Hello guys.
Like the title says, I can't boot directly into recovery mode after flashing twrp. I know the combination for booting into recovery mode but it automatically forces it to boot normally. I have to power off my phone after it starts normally to boot into recovery mode. But the problem is that the twrp disappears after it starts normally after the flash because u have to get instantly into the recovery mode (I think.) so it doesn't reset.
Modelnumber: SM-A510F
It worked at first, but there was also a problem with the recovery system because it always showed "No Command". I didn't use the latest version of odin and twrp. I only followed a guide with download links for this model. The odin flash succeded btw. I hope for some help here.
Thanks.

S8+ Stuck in Download Mode

Hello,
I bought a Samsung S8+ from someone.
Initially it worked, but during a facebook video call, the phone went off.
It was impossible to turn it back on, except in download mode. (It doesn't even boot up to the Samsung logo)
So I used Frija to download the latest OS for the G955F XEF, and flashed with ODIN (CSC File).
Odin indicates that the flash was successful but the phone does not restart and still does not turn on, except in download mode.
So I tried a flash again with Nand erase. Once again, the flash went successfull, but the phone does not start except in download mode.
I'm not sure what to do anymore: unsure:
Thanks for your help
Reboot to recovery with power + vol up
You havent said anythinf about the recovery
Nothing is happening when I try to boot in recovery mode.
Only download mode is working.
I tried flashing with Odin 3.14.4 too (had a older version before)
Use fastboot
Do fastboot reboot
Fastboot is power + volume up + bixby right ?
Nothing is happening... phone won't boot.
It is only booting in donwload mode power + volume down + bixby
