try to restart try combination (VOLUP+POWER)OR(VOLDOWN+POWER)
If no change connect your phone with usb and try to restart phone with adb command ( adb reboot )

i had that issue when i did it. had to hold all 3 buttons for 15 seconds... booted into a Safe mode. Also have to use this if im plugged into a usb and powered off (shows battery icon as charging. red text saying development purposes only) power button+volume up+ volume down.

[P600] Completely bricked (not even 'download' works). Is it hopeless?

I've searched extensively about bricked P600's and found a few threads where it seems it's still possible to boot into 'download' mode (Home + Vol Dn + Pwr) and from there it's possible to flash TWRP or some kind of recovery.
Unfortunately after attempting a flash I don't even have the capability of booting into either recovery nor download. All I get when I power on the tablet is the Samsung bootsplash and then black, dead screen (backlight is on).
Going through the process to boot into download mode then plugging it into USB + ODIN doesn't show up as a COM device.
Am I hopelessly at a loss?

When you tried to get into download mode, do you see the samsung screen turn on and off??

Yes, it flashes on the screen for a second before going to black screen.
*Edit: I've found that the tablet now wants to stay 'on' all the time. Long-holding the power button turns it off but it will immediately turn on again. When it's on external power and just switched off, the battery charging animation starts (with the spinning circle) but doesn't go into the animated 'bubble' charging display - instead it goes into the typical black screen with backlight on.

Are you using the correct steps to enter recovery mode?
1. Power off your phone
2. Press and hold the volume up button, then press and hold power until the phone vibrates
3. Let go of power ONLY
4. Use volume keys to select recovery mode on the next screen.
5. If you have stock recovery, it will say "Error". While holding power+Vol down, press and release Vol up.

[UPDATED] Recover from Hard Brick and QFIL guide through bootloader.

This guide is to recover the Zuk Z2 (plus) from hard brick state
So you might be stuck here -
Phone is not turning on
Phone Reboot and screen go black with notification light on and you are unable to switch it off.
How To-
1. How to switch it off
- First this is happening because you have locked you're bootloader
- You have black screen and led on so just hold power button then Zuk logo will be flash after that you will get black screen again and the phone is preparing to reboot but before that the led will get turn off immediately release power button.
(It's crucial timing but when rebooting your device vibrates so it's the time when phone is about to start vibrate while LED is off just leave power button)
- You have it Your phone is switched off
(Tip- Let it reboot once after that don't leave the power button and after that led will get off you have to remove finger from power button this is tricky )
2. Going to Bootloader
-First connect the USB to laptop
-After you have switched off your phone press volume up and down together and with holding buttons connect the phone to USB and you will see the fastboot mode.
3. Unlock your phone
-Remember the unlock bootloader file in your email re download it and unlock your bootloader again
- Don't reboot right away as you don't have any OS installed Even if it boot it might give problem.
- after unlocking phone you will see phone rebooted press power button reboot press volume the volume button and go to reboot option
4. For Userdata
- I suggest you to flash recovery instead of using old installed one.
- go to fastboot and flash the TWRP.
- Boot into TWRP and you will see your data on internal storage is present so just sideload ROM or if you have in internal storage just flash
( Note- in case you are using TWRP 3.4 newer roms with factory based ROM will flashed without problem in case you are trying to flash old Oreo non-treble ROMs you need to wipe like you do for normal ROM installation and reboot to recovery then flash Oreo Non-treble ROM otherwise they will not boot even after flashing)
Or
- QFIL ZUI 4.0.199ST as this QPST
- When selecting the XML file select retain userdata one so it won't erase your userdata partitions
5. In case you want to flash ZUI
- Load files in QFIL
- To reboot phone into EDL from Fastboot mode type following command
Code:
fastboot -i0x2b4c oem reboot-edl
- It will get detected in QFIL just hit Download.

Hey I have a hardbricked zuk but the only signs of life is a white led and at times a vibration when I connect it to pc there is a a port written as Qualcomm HS-USB Diagnostics 900E (COM4) . I've seen quite a lot of threads of booting it to edl and deep flashing is not a choice I'm willing to take . I'd appreciate it if you are able to help me

thanks
Thanks a lot buddy.
Bricked today by flashing a baseband.
Revived as per your guide.
Actually i'm never tensed about flashing roms, Kernels, fonts, apps, mods anything and bricking our device.
There are so many good guys to save our a$$...................
Thanks buddies....... :good::good::good::good:

Stuck at bootloader unlocked warning

I have TWRP and LineageOS with Magisk installed on my A50. Normally, when my phone boots, I get the following sequence:
1. Phone vibrates.
2. Samsung Logo appears for a very short time, with bootloader unlocked warning at the bottom.
3. A screen showing a bootloader unlock warning at the top and "PRESS POWER KEY TO CONTINUE" appears.
4. After a while or if you press the power key, an additional unofficial software warning appears in red letters at the bottom.
5. After some time the phone continues to boot normally.
My problem is that after the latest reboot ("reboot into recovery" via power menu), it gets stuck at step 4 and won't continue to boot, neither recovery nor system, even if I wait for tens of minutes.
What I've tried:
-reboot with volume +/-/poweroff
-reboot with volume volume -/poweroff
-all of the following with and without USB connected to PC:
-power/volume +/- at boot, both starting after logo screen as well as starting before logo screen, as well as releasing power at logo screen
-power/volume + at boot, both starting after logo screen as well as starting before logo screen, as well as releasing power at logo screen
-power/volume - at boot, both starting after logo screen as well as starting before logo screen, as well as releasing power at logo screen
-volume + at boot, both starting after logo screen as well as starting before logo screen
-volume - at boot, both starting after logo screen as well as starting before logo screen
-volume +/- at boot, both starting after logo screen as well as starting before logo screen
None of these helped. I just get the normal sequence 1-4 and then stuck every damn time. Can't get into recovery or download mode. Can't even power off, obviously.
Is my phone gone for good?

same **** here. for me i cant charge the battery too. but before that with about the same problems i got it to work again for a few days.
now hangs on step 4

With some help I managed to get into download mode, and from there reflash stock rom with ODIN.
Basically, you need to reboot the phone with power/vol+/vol- and as soon as the screen goes black, you release power but keep pressing the volume buttons, and also immediately connect the USB cable with the PC. Timing is key.

bro, you helped me alot, i'm stucked at this screen maybe 2 hours I didnt know what to do.
Btw, I've it just in 1 time =))

I got a way easier Method which has saved me several times
Is something i came up myself
Il be as precise as i can be so everyone understands!
1.Plug the phone to the wall (Your charger to the outlet)
2. Hold Power And Volume - (Volume down) until the phone shows the second charging animation (Which is the one after the first image of the phone charging [A circle with the lightning icon in the middle], this second screen shows a charging animation and the percentage of the battery) This indicates that the phone is fully Turned Off
3. Unplug your phone and the charger off the wall and bring it to your computer
4. Plug your cable to your Computer then back on your phone Hold Volume + and Volume - (Volume up and Volume Down) and plug your phone to your computer WHILE HOLDING BOTH VOLUME BUTTONS.
This little trick will put your phone in download mode so you can restore your device using Odin OR Flash Twrp with Odin and boot to right into Twrp (There is a way to do it without turning the phone on and having to go back to step 1, Follow this Tutorial to do it
(
)
I Hope this helps you all
And Happy Flashing!
