Develop Bugs

Uh-oh...

So my rooted phone has been vibrating recently for no reason. I googled it and came up with "power down, reboot to recovery, navigate with the buttons to wipe cache, then reboot".
I did that, selected yes to continue, and it's been doing this for a while. I'm ticked because I usually research everything pretty heavily and did not this time. What should I do now? How long might I expect this to take?

you are in Download mode not recovery mode
to enter recovery press vol+ + home + power at the same time, when u see Samsung logo remove ur finger from power only and wait till recovery starts

Thank you! Can I do that here or do I need to get out of download first?
Heck, how do I just get back to regular operation? I need to research a lot more on this...

Fixed! I took off my case this time; I think my Defender was screwing up the volume button pushing.

Firstly - I am glad you solved your problem.
Now - If you ever need to get out of Download mode then just pull the battery.

LG G4 can't fastboot/reboot bootloader

Ola!
I'm playing with a LG G4-H815.
When using `adb reboot bootloader`, the phone just boot on normal mode.
When doing the Volume Up + Power button thing, I manage to land on Download Mode but nothing happens, `fastboot` does not detect the phone. And I get this popup:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}
Reset Factory doesn't work either. Does nothing but reboot the phone as if nothing happened.

Yes, that's the Volume Up + Power buttons thing. I manage to land on this mode as described in the OP.

Samsung Galaxy tab S4 - VZW Bootloop / Splash Screen

Boot Looping Samsung Galaxy Tab S4 scenario​1- If you cannot access your device, download the ADB and latest version of Odin
2- Hold Volume Down + Power and HOLD (I'm talking even after booting, I believe this clears the cache and re-initializes
device lock
3. Repeat. . . .
Many people give up or move on to something else at this point to try to fix, if it's still not working
squeeze the front and back panels together (softly) to ensure no loose Display cable,
then... hold
VOL+ VOL- + PWR This resets the device as if you were pulling a physical battery out, clearing the cache, repairing security program. REPEAT until Tablet says cannot initiate Encryption service, and will repair itself. IT WILL REBOOT
No need to hold the buttons this time as you will see your login screen.
The Secret is VOLUME UP - VOLUME DOWN + POWER for 45-50 second intervals.
Took me a day and a half so I figured I would save you some trouble.

+Yes it is still possible that this does not repair your tablet, I do not suggest taking off the back chassis as I have seen professionals break and hard brick devices this way.
IF YOU DO - Use guitar picks and or the official phone repairkit tool. YOU WILL need it.

Question Fold3 Keeps rebooting again and again

So my phone keeps restarting and it actually opens up and nothing happens until I unlock the phone. Once I do unlock it, everything freezes and it reboots.
Any solutions guys?

A recording of what happens

have you tried to wipe the Cache from in recovery?

The phone is not loading the recovery as well. Not sure if I'm doing it right but I keep holding power and volume up when it is off, but it just boots normally.
Getting a message "PDP ... Backup Fail"

Update: I could enter the recovery by connecting the phone to the PC and wiped the cache.
Yet, the issue still there.

Maybe time to do a factory reset ?

OP, have you modified the system at all? Unlocked bootloader, rooted, and/or installed a custom recovery or OS?

Also have you added any new apps ? Maybe you added something that isn't playing nice.

You could try to boot to safe mode:
Simultaneously press and hold the
Side button
and
Volume down button
(right edge) until the 'Power off' prompt appears on the screen then release.

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Touch and hold
Power off
until the 'Safe mode' prompt appears then release.
To confirm, tap
Safe mode
.
This process may take up to 30 seconds to complete.
Upon reboot, 'Safe mode' appears in the lower-left of the unlock / Home screen.
With Safe Mode enabled, ensure Airplane Mode is turned off then test device and app functionality.

Galaxy Tab S4 stuck at boot after trying to root

Hello together
I tried to root my Samsung Galaxy Tab S4 according to https://appuals.com/how-to-root-the-samsung-galaxy-tab-s4/
There I came up to step 10 (so I flashed the two files). Now the Tablet is kind of stuck in the boot screen showing this (the same for step 8 and 10 but at step 10 i lost the ability to get to the download mode):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The only thing possible is to gamble a bit with the keys power, volume up and down to get the yellow sign in the top left showing "kernel" instead of "recovery". Otherwise if I press all three buttons together the following screen comes:
I am a complete noob in that kind of things and got no idea what to do now. There is no possibility to open the download mode to revert something, neither TWRP is shown as it should according to the Description in Link above. If possible I dont want to get anything deleted. What can I do?
EDIT: If possible I still want to root the tablet because I only see advantages in it, even I never found a good (explanatory) tutorial on it.
kind regards

Ok as I was very impatient and tried a bit, the blue screen is actually the "ODIN Download Mode". I reinstalled the stock firmware (loosing all data) (and rooted the device with Magisk later on) so the sm-t830 works perfectly again.
