Turn the phone off (in case you cant, holding vol- and power will hard reset the device)
as soon as the screen goes black press and hold the vol+ and vol- keys in and connect the usb cable, this should kick it to download mode for you to flash stock image.
i did it today itself

[Q] Stuck in Safe mode -_-

Hey guys
So my friend's got a Note 2 that ran out of charge, plugged in charge, BAM! safe mode :/
rebooted, safe mode.
removed the battery and pressed the power button for about a minute, safe mode.
the volume keys are messed up; like the volume up key works when it's booted into safe mode, but not when it's off to get into recovery. while the volume down button works when it's off to get into the download mode warning, but doesnt work when booted into safe mode.
bottom line : stuck in safe mode, weird volume key mapping. no cover or screen protector.
please help & thanks
EDIT : played with it a little more, now i'm stuck in a bootloop, with no access to recovery nor download mode.

[Q] How to boot recovery with no Power button

Hi I had my power button removed because it was getting stuck. I still managed to use it and turn it on through youtube methods. But last night something happened and my phone is getting stuck at the bootup screen. Basically I can get to the download mode to use odin, but I don't know how to get into recovery mode without the power button... Is there anyway for me to boot into recovery mode without the power button? I want to reflash my custom rom.

Hold power+home+volume up and down buttons all at the same time until it's fully shutoff. Then quickly press the download mode button combo and reflash twrp

Thanks for the answer but i can't get the device to enter download mode. When i reboot the device (with any combination of keys) it says on top left corner of the screen "Recovery Booting..." and then it enters to teamwin screen loop, no matter what i press.

Wait till its completely dead. Plug it in and press the download mode button combo. Might be your last hope

Thanks for your answer but the same think happens.
Same appened here. After a factory reset its stucked on teamview boot loop.
Anyone got a solution??
Solved by flashing cf-auto-root with odin on download mode.
Just ran into this myself haha. The device is just soft-bricked and I managed to get it into Odin mode (Download). Will let it charge for a bit then either flash stock firmware with Odin or try flashing TWRP again to see if that fixes it
Edit: flashing the latest TWRP worked
Same thing is happening to me. I get stuck in the teamwin boot loop and cannot get into the download mode to fix with Odin.
This all came about after trying to factory wipe the device due to Google Play not working correctly. I'll repost if I have success...
Just recovered my tablet from the same issue. In order to get into download mode, I had to let the battery fully drain. Then, holding the home and vol down keys, I plugged it into the charger. Plugging the charger in while the battery was drained automatically powered it up. After I saw the download warning, I released the buttons and entered download mode as usual. Then I flashed the latest TWRP with Odin.
No other combination of booting or button pressing worked. Trying to enter download with home+vol down and pressing power did not work for me either.
Good luck and PM me if you have any questions about this. I hope I explained it correctly.

H815 Soft bricked(?) adb shows device offline

Soo.... I messed up and edited the build.prop specificly the ro.build.type property. I tried to enable some debug options without validating if this would be a good idea (hint: it's not).
It seems that this has bricked my phone, the first LG splash screen shows up with the powered by android, and the second animation just keeps loading forever (making the phone very hot). And the LED flashes blue continously.
I did manage to get the device visible in ADB but it tells me that the device is offline so I can't do anything with it.
Tried booting in recovery mode (holding power button + volume down) but it just own't go into recovery mode.
Some extra info of what runs on my phone:
- version H815
- Android 6.0
- bootloader unlocked
- TWRP installed
- Rooted
- XPosed installed
Any idea on what I could try to fix it? (I guess stuck with a brick but oh well).
Thanks!
What do you mean, by it can't go into recovery mode?
Nothing is showing on screen?
Go to downlod mode either use lgup or lg flashtool to reflash the firmware that you are on... Do u remember which firmware you were on ?
Thanks for the replies!

I meant that it just boots 'normally' when I press those buttons, it shows me the first LG logo and the second animation just hangs, whatever I do. I tried all sorts of combinations with the power button + volume down. (Keeping it pressed, briefly letting it go after the lg logo and repressing them).

I don't know exactly which firmware I was on but I can't even get my phone into download mode (same as my other response, pressing volume up doesn't do anything).
The recovery and download mode used to work but I have no idea why it doesn't now...
When booting the phone, hold the power button and volume down button simultaneously, when LG logo appear, push the power button again. You should see the white screen, where you choose "YES" twice. Then the phone should kick you into TWRP or different recovery mode.
But how the hell editing build.prop can mess with recovery and download mode? Sounds incredible

Maybe he has bootloop issue... ILAPO
Yeah I have no idea why the buttons aren't working for me. After a lot of searching I found this thread:
http://forum.xda-developers.com/g4/help/soft-bricked-device-t3248144
Which is basicly the same thing I'm experiencing, ADB comes online for just a brief second (kept spamming the reboot recovery command) and got in TWRP and I just flashed another which worked fine.
Odd thing is, even now my phone works I can't start recovery or download with the hardware buttons...... oh well, thankfully adb works as it's supposed to.
Thank you all for your help!

Bricked and bootloop after running fastboot oem lock

HTC 10 was running Viper10 ROM, booted into download mode and ran fastboot oem lock so I can RUU and send my phone back for a return.
Phone now bootloops immediately after turning on, HTC logo comes on for a split second and it just turns off again. I can't access or do anything. I can't boot into recovery, the phone won't let me do anything.
Am I ****ed?
I had a very very similar issue. Was getting bootloops right after the bootloader which is a good sign, fyi. It's only a soft brick.
I fixed the issue by restoring my stock firmware via TWRP. that's always your safe place and seeing you're a senior member I hope you made TWRP backup before you got funky with flashing.

How do I boot into TWRP?
As soon as the phone turns on, it just instantly turns off again or it loops when it's plugged in until I unplug it.
No button combinations work and the PC won't detect it.

Phone was just S-on with unlocked bootloader.
I held down both volume buttons and the power button and it took me to bootloader mode, went to download mode from there and the RUU flashed and now phone is relocked and back to stock.
Thanks for your help.
