[Q] Problem when attempting to flash TWRP - G2 Q&A, Help & Troubleshooting

Hello,
I rooted my phone with no issues. Then when preparing to get TWRP on my phone I was setting up ADB via this tutorial
http://www.youtube.com/watch?v=XslKnEE4Qo8
and got the phone to be recognized as device in the cmd window, but when doing the adb reboot bootloader step, the phone just reboots to vzw logo and then the home screen. After being stuck at that step I tried this method http://androidfannetwork.com/2013/09/18/twrp-recovery-available-for-lg-g2-att-and-verizon/ using flashify but after flashing and hitting the reboot button my phone wouldn't turn on and thought I bricked it until I waited a few and then had to hold the power button down for 15 seconds and it turned on. But now I can't get to the white screen reset menu (Stock recovery menu?) using the power+vol down method. Is my stock recovery borked? Any tips on how to get twrp on my phone, hoping it installs over the broken stock recovery. Thanks in advance for reading this.

[Q] Stuck in Bootloop, tried everything.

So I just picked up this phone today from Verizon. Rooted successfully and tried installing TWRP via Flashify. Now I'm stuck in TWRP and can't even get Download Mode to come up. I've tried wiping, using the scripts in both ADB and TWRP, and LG Factory reset. Please, if anyone has any other ideas. I would be grateful!
I'm guessing you clicked "install boot img" instead of "install recovery img" in flashify, correct?
Hold the power button down until your phone is off. I mean, you're going to be holding for 15-20s. The LG logo will flash on, then go back off pretty quickly. After that your phone is off. Then, you should be able to get into download mode by holding the vol. up arrow while plugging a USB cable into the phone. Follow the "return to stock" guide of your choice and don't click install boot img next time you try to install TWRP.
I think you're right. I'm finally going to give it a shot now. I was on the road but thanks a million. I will report back on results.

[Q] Note 3 n9005 stuck in 'reboot recovery' after failed mobile odin

I tried mobile odin to re flash my already rooted and cyanogen'd note 3 back to a root ed stock rom,
After hitting the go button it reset and now will only reset into reboot recovery mode.
I have since tried odin connected to a pc and this shows it as added so I think it is connected ok, I have a rom and that shows up as fine and when I click start it reports the SetuConnection message and just sits there.
The problem I have is that it won't reboot into download mode no matter what i try.
Additionally, when I boot I see the recovery reboot message for a second and the Samsung logo and then the screen goes black and stays that way. Bth the capacitive buttons vibrate when you touch them but do nothing else and the volume seems to change the volume up and down. Still with the black screen though
Anyone come across this or have any ideas.
Ta
it could be your recovery image is broken somehow. make sure your phone is off. try download latest custom recovery. i recommend either twrp or philz touch cwm. while phone is off, press home + power + volume down. when you see a warning screen, press volume up. this will go to download mode. flash new recovery via odin.
i had issues before with custom recovery causing recovery boot loop. the only confirm working recovery for me is cwm philz touch and twrp.

att lg g6 recovery

so i was just playing around and used adb to and my PC was able to find adb devices and i was run some simple commands but when i try to reboot to boot loader it looks like its trying to as i hear plugged in sound after phone booting but immediatly disconnect sound and it boots normally and i tried rebooting to recovery and it booted to a screen with robot with a red exclmation mark and no command on the bottom and i tried some key combinations but nothing worked except holding vol down and power boots it back, does this mean att or lg have not installed recovery or is it blocked, i am aware bootloader is locked but it should still boot to recovery as it did in the g2 days that i can remember, any ideas, thank you.
update and few questions,
in the lg g 2 days on att non rooted phone the button sequence would take you to factory erase screen and if one accepts it it erases and then boots into stock recovery but now on lg g6 it does not , it erases and boots normally, and i tried adb reboot bootloader and it wont work and i tried adb reboot recovery resulting in flat robot with red exclamation mark and NO COMMAND on the bottom, i am just trying to understand, is it that secure boot in nougat is locking me out or is it att that disabled recovery and fastboot, any thoughts appreciated.

Tried to root, recovery flashed but didn't boot, now phone won't reboot.

Hey guys and gals, I decided to take my new PH-1 and root it after getting the latest OTA (this is an unlocked Sprint variant). I flashed the twrp for my build and there was an error, tried it again and the same error so I rebooted back into fastboot and it flashed but I didn't reboot into recovery. Flashed it again and booted into recovery but it was just a black screen as if the phone wasn't turned on. The closest I've gotten to recovery was the android laying down and it said "no command" but I forced a reboot at that point (I think I could have pressed up on the volume and pressed the power button to get to it from there but I haven't been able to get back to it).
I ended up flashing a modded boot image for root with Magisk 14.3 and that worked but I can't reboot my phone, it just goes to the blank screen like it isn't on and I can start it up again by holding the power button down for 15 sec. and it seems to function fine but I can't flash the OTA file to go back to complete stock or to go to the Oreo beta.
If anyone could give me some insight into this problem or a way of fixing it I would grateful, thank you.

Stuck at "Google" screen after TWRP wipe

Hi,
I did a TWRP wipe (everything checked) to prepare for a restore to stock, but my device is now stuck at the very first "Google" screen with the pad lock icon at the bottom. How do I get it to boot?

So since everything was checked, that means you wiped the system partition. The device will not boot if you do that unless you flash a factory image via fastboot or new ROM via TWRP
OK, I thought wiping /system would just bring it back to factory state. 2 questions now
1. How do I get to recovery when it's always stuck at the Google screen with no adb access? Would I have to wait for the battery to run out (hence turn off), charge it for a while, then use the buttons to boot to recovery, or is there a faster way?
2. I am actually trying to revert to stock ROM (downloaded at https://developers.google.com/android/images#angler) by following step 10 of the Heisenburg guide (https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928) which advises me to use fastboot to flash the individual images. In my case, how do I boot to fastboot?
OK, so I managed to boot to the bootloader and run the following commands as per the Heisenberg guide (using the stock MTC20L firmware)
Code:
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash boot C:\angler\images\boot.img
fastboot erase cache
(above command is unnecessary on Android 7.1.2 and above)
fastboot flash cache C:\angler\images\cache.img
(above command is unnecessary on Android 7.1.2 and above)
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash vendor C:\angler\images\vendor.img
Everything was successful, and I did a fastboot reboot after that.
However, my device still doesn't boot up. This time. It's boot loops for a few times before turning off.
I tried booting up to bootloader with power/vol-. Curiously, I can now only do this when cable is connected. If cable is disconnected, the orange LED just blinks once when power button is pressed, and nothing happens. Once cable is connected, then I'm able to boot up to bootloader with the button combination. I then retried the flash process again, but still no go. I noticed after fastboot reboot that the orange LED blinked a few times before rebooting and boot looping.
Kinda stuck now, any ideas?
Try booting into recovery and doing a factory reset. I've had that happen to me a few times after flashing factory images and a wipe in recovery always fixed it.
Just for future information: if at any time the device is stuck in a bootloop you can get it to robot into recovery by holding the power and volume down buttons for 10 seconds, or get it to boot into bootloader by holding power and volume up buttons for 10 seconds.

Thanks. Booting into stock recovery shows an exclamation sign with "no command", since I don't have TWRP anymore. Would I need to first flash TWRP before I can do a factory reset?
I just tried flashing to the same sock firmware as before the problem happened (7.1.2 N2G47W) but still same problem. I notice that after the Google logo disappears and the screen goes blank, the orange LED blinks 10 times before rebooting.
Edit: Tried factory resetting in stock recovery (by holding down power button and pressing vol+), the rebooting after factory reset. Still getting a boot loop.
OK I solved the problem. Apparently if you reboot after the flash, you need to disconnect the USB cable, else it will boot loop.

brother help me! i am facing same issue
first little info abt my device.
my device was running on android nougat with twrp recovery installed but the device was not rooted.
so get back to stock and install oreo I followed every step given on http://www.androidexplained.com/nexus-6p-revert-stock/ but somehow my phone is stuck at bootloop with no recovery installed.
Please help me here.
As per the Heisenberg guide, if you don't install root (SuperSU or Magisk), TWRP won't stick, so you'll go back to stock recovery.
For me, simply unplugging the USB cable after rebooting after a flash solved my problem. For some reason, if the cable is connected during reboot, it would boot loop.
brother, somehow I managed to install twrp. but everytime I touch it 2-3 times the phone gets switched off.
then it keeps rebooting to 'Google' logo.
can you tell me what should I do now?
