[Q] Nexus 4 stuck on bootloop - Nexus 4 Q&A, Help & Troubleshooting

This morning I woke up and my Nexus was stuck on a boot loop. I tried to flash stock (choosing soft-bricked/boot loop) with the Wugfresh ToolKit but in the black command box I see the message/error that it is not available remotely for locked devices. I then went back and put the phone in the bootloader and tried to unlock it. I watch it as it says it is successfully unlocked, however as soon as it reboots automatically it gets stuck in the boot loop. If I power it off and the back on it is locked again. Can anyone suggest anything? Thanks in advance.

So your bootloader is now unlocked? Did you try going into recovery and wiping cache, Dalvik, and data? Did you try flashing a stock rom manually?

No, it locks again when it (automatically) reboots and starts looping.
I then went back and put the phone in the bootloader and tried to unlock it. I watch it as it says it is successfully unlocked, however as soon as it reboots automatically it gets stuck in the boot loop. If I power it off and the back on it is locked again.
Is there a way to stop it from automatically rebooting after unlocking? If so, will that muck it up?

not being able to unlock is a sign your emmc memory is bad. I'm afraid there isn't anything you can do except warranty if you still have it. The mother board needs to be replaced.

Can no longer install factory images, results in app loading bootloop

So pissed off and annoyed now....
Attempted to upgrade to marshmallow, then tried root over and over again. I get that it's a wip, but no such luck. Eventually I got annoyed and decided to just wait so I tried downgrading back to 5.1.1. For some reason now trying to root that results in boot loop as well (even tried older supersu). After a couple attempts with no such luck, tried to install stock back and now before even trying to root, the device doesn't want to boot up properly anymore.
I tried fastbooting bootloader, boot, recovery, and system, once I try to staRte up normally, android boot logo goes through but the first startup "upgrading apps" goes through its list and right after finishes, says "starting apps" but almost immediately boots back to the boot splash screen, where the process repeats itself over and over.
Trying to reflash everything results in same issue now. I've tried at lEast 4 times. Have I bricked my brand new nexus player?
Hoping for some answers so I can sleep on it. Pissed off and annoyed now. Ugh.
Figured it out. Didn't know how to bring up commands in recovery mode. Had to factory wipe system and cache.
Sorry for the wasted post. Mod please delete this if possible. Thanks.

Stuck on"Your device is booting now"

So, I unlocked my bootloader, flashed a revolution recovery then I got my phone stuck on that screen. After a lot of tries and countless volume up and down random pressing I got the phone into e-recovery and I got it to work. The phone experienced
a lot of lag issues since then; so I tried a factory reset. The phone after reset had no keyboard but the google voice activated one.
So I relocked my bootloader and decied to try it again .... I unlocked the bootloader, flashed a TWERP recovery, and the phone got stuck again but this time for the life of me I can't get it to open.
It shows Huawei logo for 1 second then the screen that says:
"Your device has been unlocked and can't be trusted.

Need help! Unlocking bootloader without using the app

Good day! I wanted to ask how to remove the bootloader for zenfone max (the old one 2015 model) without using the app from ASUS as I cannot really use my phone. It boots then restarts. I already tried Wiping/Factory Data reset and Wipe cache with the Power and Volume down (Is it Recovery mode?) but still bootloops, by the way when I factory reset, my phone showed "Unknown volume for path /factory". My friend told me it could be that my OS was corrupted. So here I am wanting to unlock the bootloader so I could install OS for my phone.
**Note1: Sometimes it would boot to the "Welcome!" screen, then when I reach to the Wifi selection, it would always restart.
***Note2: This bootlooping happened when I restarted my phone because my wifi suddenly couldn't connect. After I restarted, it looped.
Noob here btw. Sorry and I would be glad to provide additional information if needed be.

ZTE Axon 7 Mini Bootloop Brick(?)

I was trying to boot into recovery after I flashed TWRP but it gave me the "Your device cannot be checked for corruption, please lock the bootloader"
Which, like a complete idiot, I did.
Now my phone is stuck showing the ZTE logo, turning off, and repeating. It won't turn off either, so it's stuck in this loop? I tried using Tuliptool.

That's just a message warning you that the bootloader is unlocked. It would have disappeared in 5 seconds and booted recovery, so you should have let it continue. Nothing was wrong.
Your battery is probably dead by now due to all that bootlooping. I'd try unlocking the bootloader again, if possible.

All of my previous attempts to unlock the bootloader have failed, either not functioning or due to oem unlocking not being enable as its factory reset.
I'm not sure if it is possible to unlock the bootloader, so I'm here

Help unbricking my G6 997

I have an older LG G6 thar ran into some custom ROM issues. i got a new phone so its been shelfed. Recently a friend broke their phone so I thought I could revert mine back to stock using the LG Up tool. it detected the correct model, ran the process but it must have got cut off or something because it rebooted but it never loads the ROM. Left on its own it boots to the LG logo and doesn't go further. Attempting to boot into recovery or into download mode shows a rainbow circle that says erasing for a second then reboots on its own. I can get it to the MEID screen but that doesn't obviously do anything.
Anyone know of any options or am I just brickled?

Quick update, I got it into fastboot mode but Im sure what I can from here. Any suggestions?
nevermind I got it back up and running. I tried a lot of stuff like flashing the laf to get back into download, flashing a recovery, unlocking the bootloader again, with a reboot between each step.
What eventually worked was unlocking and then relock the bootloader and after a reboot it was working again. Im not sure why this worked or if it would work for anyone else
