[Q] Bootloader Issue: screen never turns off while powered off+charging - General Questions and Answers

Recently I dived into flashing custom recoveries and discovered TWRP, which I have no problems with (as in it does everything I want).
However, after unlocking the bootloader and flashing the recovery I found a bug/glitch/issue, I'm not sure. Whenever I power off my device, an LG Optimus G (sprint), it does so just fine. When I plug in my charging cable it turns on, showing the Google logo with an unlocked padlock at the bottom, then shows a screen with a charging battery indicator/animation. About 10-20 seconds after this the screen shows nothing but is still on, as if it were just a black image. I cannot power the device off completely, and when I try to it just repeats this. My phone will warm up after a while, so the only way to charge it safely is to keep it on all the time.
How can I fix this issue w/o relocking the bootloader?
I have an LG optimus G ls970, Rooted, Stock ROM, Unlocked bootloader w/ TWRP recovery.
Any help or answer to this will make me super happy, thanks in advance.

[Q] Stuck! Phone does't turn on and does not charge

Hello guys I have been struggling for the past week, my LG G2 phone has been rooted, I flash a custom recovery TWRP then I lunched to my stock rom I then tried to update my firmware to 4.4.2 kitkat the update was downloaded successfully, then it told me to reboot, so I did phone switched off then I was stuck on a boot loop but this time it was a boot loop with a error message on the left top corner. and then it would take be to a dim back screen. I searched the entire week to find a method to get me through the start screen and I found this -> NO Recovery mode, No download mode, after OTA on rooted LG G2 http://forum.xda-developers.com/showthread.php?t=2582142 I done exactly what it was showing, then my phone switched off and now it won't power up. Then I tried turning it on NOTHING phone does't show the LED charging lights, does't respond to the usb being plugged in can't do ANYTHING I am guessing the battery has died so now I don't know what to do, either contact LG or should I try getting a battery that is fully charged or even use a factory cable any ideas guys ?
Call LG support.

Stuck in "Warning Bootlaoder is Unlocked" Loop and Need Help

I have looked at multiple guides on this and other sites, googled and tried stuff and I cannot resolve this problem. Hopefully I am posting in the right place.
I took the jump and unlocked the bootloader on my Moto G first generation, XT1034 successfully. I flashed TWRP 2.8.60.xt1034.zip with adb and this was successful. Then I flashed Super SU 4.6 Update and that was successful. I got into trouble I guess when I tried to flash Cyanogenmod 12.1 nightly. I used TWRP to flash via install. The flash had an error, which unfortunately I didn't write down. I believe it was something to do with a partition. However, it looked like the flash failed. At this point and for hours I have been trying to fix the "Warning Bootloader Unlocked Loop I am stuck in.
I have been able to get into the phone and flash via adb commands. I've tried several commands suggest to fix this that I have found in forums. I have tried flashing several recoveries including an older TWRP per the method in this thread, a clockworkmod - and the original 2.8.6.0.xt1034. When I get into the phone bootloader which is available, I have not been able to access any options in recovery. Pushing the power button on recovery leads to a blank screen sometimes followed by a recovery starting or a Motorola Logo starting up and a couple times a recovery. TWRP has started a couple times, but never gets past the intro screen, where it locks up. clockworkmod (clockworkmod-6.0.4.7-falcon.img started once after flashing through adb and gave me flash options. I tried to sideload, didn't understand, went back and the recovery locked up. These recoveries no longer load at all.
Through all of this the "Warning Bootloader Unlocked" logo screen comes up after plugging into the computer (Windows 8.1).
Example, I open the phone bootloader by waiting for the phone screen to go from the "Warning Bootloader Unlocked" screen to blank - it cycles from logo to blank. If I'm quick the phone and hard boot the phone will boot into bootloader. I connect to the laptop through USB. When I toggle to recovery and hit the power button the screen goes blank, the Motorola Logo pops up, goes blank and then the "Warning Bootloader Unlocked" appears. The Laptop then seems to connect and disconnect as the Warning screen comes on and turns off.
The factory selection just goes to a blank screen.
I would really appreciate some advice on how to get the phone back to a state in which I can work with it and try again. It is very difficult wading through all of the information out there. I've learned a lot through this issue, but can't take it any further.
Thanks, Jeff
Solved - Stuck in "Warning Bootloader Is Unlocked" Loop
This resolution took many hours to figure out, but I finally got there with this guide - http://forum.xda-developers.com/showthread.php?t=2542219, this thread - http://forum.xda-developers.com/showthread.php?p=54855457#post54855457 and this thread - http://forum.xda-developers.com/gen...e-firmware-t3042687/post59139823#post59139823.
I tried RSD Lite on different computers and USB cables I could not get the device recognized. So I ended up with the MfastbootV2 method to reload stock firmware, which I found on the firmware thread above - this was big, as my phone is with Wind Mobile in Canada and the link is the right one. The only thing I picked up from a different website was to use a computer with USB 2 ports. This is what I did, but I don't know one way or the other if USB 2 was needed. .
Can't thank you hard working guys enough for the time you take to put these threads together. I'm back up and running. As a bonus, after a big clean up in the process, my phone is running fast again.
Thanks everyone.

Possibly hardbricked moto G XT1033 Indian model.Please help.

Hello!
I recently flashed my Moto G with the unofficial LineageOS 16 rom by allstargaurav. Kudos to him for his work.
I unlocked my bootloader, got TWRP, flashed the rom, flashed Gapps,Magisk and started using it normally.
One night, after using it with the battery at 30%, I left it as it was and did not charge it.
The next day, I saw that it was not booting up at all. I plugged it in and the white led light started and did not go off.
The light was constantly on. I searched on google to no avail.
Nothing works and I have pressed the power button and power+volume down for more than 5 minutes.
I cant get to the fastboot menu or the TWRP, the phone doesnt power on at all so I cant do anything or get a logcat.
Please help!!!!
I also got the watchdogs boot animation. That is all I have modified.
Please tell me what is wrong and how to rectify it.
Please help quickly.
I am at wit's end and helpless. I should also mention that this was my first time flashing a rom on any device, but I followed the instructions very carefully.Before this the phone was on stock Lollipop rom, stock recovery and locked bootloader.
Thanking anyone who helps or even replies in advance.

Being unsure what the problem is, I also followed FabioSan's guide on unbricking the phone, but I got stuck on the part where we go to the device manager console as my PC would not recognise the phone no matter what I did.
Also, the warranty has expired long ago as the phone was bought in 2014 and it was only a 1year warranty.
Therefore, I am considering giving the phone to the moto support centre. I will also try replacing the battery as it may be a battery problem considering my symptom of the white light does not fit any hardbricked phone's symptoms. Will notify if it works.
Till then, please help and suggest what the problem might be.

J700F Black Screen

Hello, what could be the cause of the black screen? I can manage to boot it up to recovery mode(TWRP) but after a few seconds it goes into black screen. Same goes after seeing the samsung logo. I can't seem to boot into odin mode as I tried multiple times it only shows the samsung logo and then boots into samsung logo again. I also tried connecting it into the computer but the device won't show up even though I unlocked the oem. When charging it shows the battery indicator fine. It shows error on the upper left: Custom Binary blocked by frp lock. what can I possibly do to make it work again? Thanks! It's on custom rom: onkiller-os v2.0 final and custom recovery: twrp 3.4.0.
The oem Unlocking gets enabled sometimes if your battery runs out.
try flashing the stock rom again, it can help sometimes. it happened once to me as well. My phone died once bcuz the battery ran out and somehow oem unlocking got reenabled

Thanks for the reply. ah, But the oem is enabled and can I flash the stock rom without accessing odin mode? I can't seem to boot into it.
Boot into download mode, by pressing power, home and volume down button
Try that

My mom's phone got bricked

Hi, a few hours ago my mom's cell phone (Motorola Moto One XT-1941-3), turned off out of nowhere and when I try to turn it on, the android one logo is displayed and it turns off, repeating itself indefinitely without being able to start recovery, just fastboot.
I tried booting twrp through fastboot, but the oem is locked and I don't want to lose data
What I can do?
