Recovery/Bootloader questions - Verizon Samsung Galaxy Note II

How can I tell if my phone is on the factory recovery and bootloader? I don't even know what to look for. Under about phone nothing says modified or custom and stuff looks stock but i'm not sure...

did you try and unlock?
if you power device off, press and hold volume up/home/ power buttons, the device will boot into ASR(Android Stock Recovery), If the device boots into TWRP recovery your unlocked.

Phone will not boot into fastboot mode, phone will only boot into stock recovery

Hi,
No matter what I try to do, when I turn on the phone (LeTV x800) with the power down button held in, the phone loads an image of a penguin and then reboots.
When I hold the power up button in and turn on the device it loads the stock recovery. But won't allow me to flash TWRP recovery which I have renamed to the devices required nomenclature (update.zip). It says it is corrupted.
Please help!

Somehow I Can't get to EDL mode

I just officialy unlocked my bootloader because I Can't enter EDL mode somehow. Tried everything, EDL scripts, adb, holding the volume buttons...
The phone always restart the the system (it works fine). This is weird because I can't do factory reset either, it always boots back into my system.
Can somebody help me in this?
If you have an unlocked bootloader, why do you need to go to EDL mode instead just use fastboot.
Care to explain better?
The issue is: I flashed TWRP with fastboot. When I try to boot into it (Holding Volume up + power) i just get back into system.
This is just weird, as I can't do a Factory Reset either!
Download edl7.zip file from xda thread and go into fastboot mode and double tap on cmd file...your device will go in edl mode (red led blink)

EDL is for flashing fastboot files for locked bootloader as flashing through fastboot doesn't work. If your bootloader is unlocked you can just use fastboot. For TWRP are you getting any error while flashing it, if not you should boot into TWRP by holding volume down and power button with your phone turned off.

Hey man. Thank you for your help. But I think that I'm not being clear on what my issue is. I have some experience on flashing twrp and rooting. But never faced something like this before.
I can't even do a factory reset (from the settings menu) as the phone restarts and just goes back to the system. I flashed twrp but when I try to boot into it I get back to the system. I try to reboot into bootloader via the update menu and the phone resets and just get back to system.
It's just as if I can't acess the bootloader menu at all.
That never happened, try holding volume button before pressing power button. You can also try it through adb, make sure you have usb debugging turned on. For fastboot use adb reboot bootloader and for recovery adb reboot recovery

Yeah, tried that too. This is just way too weird to be normal. I'm sure that I did everything right.

LG G5 can't boot into recovery.

That's not an error message, that's the message you'll see every bit if you unlock the bootloader. Do NOT relock your bootloader after installing custom recovery. Also to get into recovery (provided you installed it correctly and it wasn't erased after it booted info Android) is to turn your phone off (or pull battery) and then hold volume down & power button, one you see the LG logo let go of the power button only (still hold volume down) for about 1 second and then press the power button again and hope (never let go of volume down). It will ask you if you want to reset your phone, select yes two times and you will enter TWRP. If it actually resets your phone, TWRP isn't installed. Usually after installing TWRP you need to pull battery then use above method to boot into recovery, mount system partition and use TWRP file manner to delete come named "recovery from boot.p". You can also go ahead and install SuperSU or magisk (use magisk if you need to be able to pass safety net). Hopefully this helps you, also next time please include what model phone you have and what steps exactly you did as it's easier for others to attempt to help you.
Mines a H850 running nougat as well but thats the only thing it wont boot to recovery because when i hold down the volume down button and the power button the lg logo shows up but then after 4 seconds that google message will pop up and that gets in the way of doing the method to get onto recovery thats my problem

You have to follow exactly what I posted earlier. If you do that, it will show the factory reset screen which is you have TWRP installed, it will not into TWRP.
1) Power off phone
2) Press and hold volume down (do not let go until you see factory reset screen)
3) Press and hold power button, when you see LG logo, let go of power button for 1 second and then press and hold again.
If you do not follow step 3, you'll never be able to boot to recovery using button combo, it will just go to that message and then boot into Android.

Thanks for that! I got it working cheers
I'm actually having a similar issue too.
To clarify, I'm using a LG G5 (h830 variant) that is running resurrection remix.
I remember getting into recovery just to flash the updated modem and bootloader zips so I can fix the issue with powering off the device.
Now I noticed after doing that, I cannot get into recovery either with rebooting or with the button combo.
Thankfully I am rooted with magisk and this is probably the first time that I encountered this issue.
I don't want to further risk anything (because my phone is set up and don't want to lose any data) but would flashing twrp through the official app work just fine?

I know this is old,Just wanted to say thank it worked for me...
Been a while since I used LG and never with official bootloader unlock so I was thrown off by resetting to recovery as at first i never had the lg screen just the bootloader warning start
For those T-Mo G5 (H830) with unlocked bootloader, you will not see any LG logo. Once you see the lcd backlight comes on, immediately release the power button and press it again, all the while holding down the vol down button.
When you see the bootloader unlocked phone is unsafe msg by LG on the screen, it will already be too late and past the stage where you can boot to recovery. Simply power down and redo in that case.
(Needed to do the above as the latest Magisk 20.0 broke root and adb on H830, thus there was no way to get into recovery other than using the physical buttons. The Magisk Canary version of 20.1 works though.)

Build.Prop edit mistake

Long story short, I messed up and I regret it. I edited the SDK 2 API levels up to get an app to possibly work and didn't think of the consequences of everything else.
I was running 8.0.0 rooted and am unable to get into recovery as the main boot of android is messed up where all apps result in continuous errors and when trying to enable usb debugging in the settings, the settings crash.
If I could get into revovery mode, I can fix it. The issue though is holding power + vol down does not work. I am not sure how to get into the recovery when the v30 shows that conformity screen on boot when the boot loader is unlocked. I was able to get into fastboot mode but on that screen it says i need to enable OEM unlock. Sadly that is not working as settings crash when trying to enable.
Would anyone have any other ideas to get to recovery?
Let me know if any more info is needed.
EDIT: I do have LGUP installed and does see the device. I would prefer not to have to fully reset the device if possible. Can LGUP boot the device into recovery?
What you described (just holding power and volume) will not get you into recovery... the proper sequence (aka the "button dance") is more involved than that. If you're only holding down those buttons, then you're not doing the process... do a search to see what it is (I believe you need to release and then re-press the power button... but I don't recall, so certainly don't take my description as enough info.
You also said you can boot into fastboot - you may be able to "fastboot reboot recovery" to get into recovery... some phones respond to that.

LGUP can get you to Download mode but not Recovery.
You can boot to Recovery (TWRP) with hardware button dance.
8 sec Power + Vol-, and when it shuts off, release both, immediatly press both again (at the same time), and as soon as the LG V30 logo appears, release power and press/hold it again.
Should get you to the factory reset menu, confirm twice with "yes" (navigate via vol/power buttons), and TWRP should boot fine.
Might take a few tries to get the right timing for that

For that, remember the annoying bootloader unlock warning is part of the boot sequence, if you still have that.

@schwinn8 -
I ended up doing a clean flash with LGUP as I need my phone for work and thought this might as well be a good time to update from stock oreo to stock pie. I wish I had remembered the master reset method as that should have throw me into recovery, I was releasing and then holding both power and vol down when it should have just been releasing power and then holding while continuously holding vol down. Along with fastboot, a while back I had to reinstall windows and so not thinking things through, I did not have working fastboot drivers and didn't initially realize it.
Mistakes were made :/
I very much appreciate the reply.

Recovery Mode when unlocked

I can not boot into recovery mode on my unlocked S7 since I need top press power to get past the warning, but that only works if no other button is pressed, and I then boot to the system not recovery. I've watched multiple youtube videos and read up nothing seems to work as you need to hold Power and Vol+, yet you can not do this with an unlocked boot loader.
ERIC
You need to hold it through that warning.. so soon as screen goes black press and hold power and vol+ until you see recovery screen.. or u can use adb reboot recovery or if rooted theres apps that can reboot to recovery or even from magisk manager
