[Completed] LG G3 Sprint (LS990) Stuck on Boot, Will Not Enter Download Mode - XDA Assist

This morning while trying to root my G3, I ended up soft bricking it. Fun times. My biggest issue is that every walk-through on fixing it requires a boot into download mode, which does not seem to work. I can boot into recovery mode just fine, but when I hold volume up and plug in the USB cable it displays my current battery level. I tried the same process with the battery removed, and it did the same but instead of showing the battery charging, it just had a yellow question mark sign.
Thank you for any help you can give!

[Completed] [Q] Need help with my LG L40. Is it rare bootloop problem?

Hi guys, I have LG L40 for 6 months and successfully rooted from xda tutorial.
Now I have problem with this phone that has a bootloop problem..
I have checked the tutorial how to fix it, yet it still not working on my phone..
They say I can just use volume up/down + power button to go into recovery mode, but it can't..
Then I try to flash my phone from PC, yet the step that I followed http://forum.xda-developers.com/showthread.php?p=36351786#post36351786 can't be practiced on my phone..
My LG logo just blinking when connected to USB cable..
And it won't charging.. It's looks an empty battery and keep restarting itself..
I don't change much on my phone, instead using xposed framework and it is only usual script like youtube adaway..
Can u guys help me?
Hi,
That unbrick guide you linked was not for your device. If you flashed files for another model, you may be in trouble now.
I can't find anything relevant on XDA for your device and issue. It could be bricked. It could also have a stuck power button from your description.

[Completed] ADB - Device Unauthorized

So today I installed a zip file on my LG G4 . After installing it I tried to boot the phone from TWRP, but it got stuck in bootloop. When I try to enter the recovery by pressing volume down and power button nothing happens. Sometimes the phone vibrates or the boot animation slows down for a second but then it goes back to the animation. If I try to use the ADB to boot into recovery (or to do anything) it gives me a device unauthorized message. This is probably due to the fact that I recently reinstalled Windows and haven't connected my phone to my PC to confirm USB debugging. So all in all I am locked out of my device without being able to do anything. I am asking for help to solve this problem since I can't figure it out.

[Completed] Non-typical bricking of ZTE Nubia Z5s

Hello!
I have been trying to flash a new ROM into my ZTE Nubia Z5s phone. I have tried many versions, but the majority of installations didn't end successfully. However, after the last try, the phone got stuck on showing the logo. After waiting for nearly an hour, I started to think that it's not going to change and shut the phone down. However, after turning it back on, the screen started to show weird color combinations (similar to how a physically damaged screen behaves) after the logo. Physical damage is rather impossible, because both the logo and the battery indicator look fine. The problem is, I can't reach recovery mode by pressing VOL+ and Power, and I also can't sideload a new ROM (ADB can't find the device, and the phone is being treated by my PC as a flash drive). What can I do now? Any help would be much appreciated.

Hi there and welcome to assist,
Unfortunately there is nothing about your question/device on XDA forum. Try a Google search first or contact the manufacturer for stock firmware and flashing instructions.
You'll have to create an account to post in the main forums if you have any other questions.
Good luck
