[Q] Stuck in a weird boot loop - Nexus 10 Q&A, Help & Troubleshooting

So I had it completely stock. I went and unlocked the bootloader, using the nexxus toor toolkit.
It then rebooted, and it shows the unlocked symbol and then starts the animation and that just keeps going and going.
If I hit the power and volume up the only screen I get to is where it shows it downloading. I cant get it into the bootloader, etc..
Any ideas?

Try holding both volume keys while powering on, seems some of the n10s have this method to get to bootloader
Then follow the steps in 3rd post here to get up and running

Try not to use toolkits, seems all to often they're more trouble than they're worth

[Q] Black screen after downgrade

I was running Cyanogen 6.1 on my HTC Dream fine, after that i decided for full downgrade. So i searched google for it and found the cyanogen wiki for doing it. I followed each step and after flashing DREAIMG.NBH to my phone, it restarted. And so it entered a boot loop. I took off the batery and then tried to enter recovery or the bootloader.When powering the phone normally, i see the T-Mobile logo, and after that, the screen turns black. Whenever i try Camera + Power, after the logo it goes to black screen. Home + Power points the same thing and so does back + power. Fastboot doesn't seem to work even though i have all drivers properly installed and the Android ADB Device shows under Device Manager.
I know i messed up because i didn't wipe before the downgrade. If there is any possibility to repair it? If so..what is to be done?
Thank you in advance!

Bricked my phone, need some help

Got a brand new vs980 from Verizon with stock OTA 24A on it. I rooted and then used the KITKAT 24A OTA FREEDOM file from this thread to try and install TWRP 2.7. It ran, asked me if I wanted to boot into recovery. I chose yes. It appeared to have worked fine. However, now my phone just gives me the ERROR: boot certification verify screen. I've tried to get into download mode, but it never makes it past the first screen (dots). It never makes it to the screen with the progress meter and the usb icon. It seems to be properly bricked. Is this thread my only hope?
C'mon guys, this is a crisis. On my way to work this morning i had to listen to the radio! Like, with commercials and stuff.
Any luck? My phone is doing the exact same thing. I can't get into download mode or fast boot. The LG sign pops up, the error flashes for less than a second in the upper left hand corner then the screen goes blank and does nothing else until I hold the power button for 10 seconds or power button + volume down key, then it just repeats the LG sign and message all over again. We're screwed brotha

[Q] Nexus 4 stuck on bootloop

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.

Oneplus 2 boot looping

problem that came with it is the bootloop when i try to (re)start the device. The phone flashes the OnePlus-logo for half a second, vibrates, and starts again, over and over. The only way to get the phone out of the loop is by pressing POWER + VOLUME UP and booting into fastboot. Then i can do all the fastboot-commands on my PC, but i can't get into the recovery or flash anything because the bootloader is locked. Trying to 'fastboot oem unlock' only results in the device restarting and getting stuck in the bootloop i mentioned before again.
I managed to get the phone to work a few times by executing 'fastboot continue', which either starts to show the charging battery symbol or booting up like normal (about a 50% chance I'd say).
ADB commands can then be executed, but I'd need a way to flash a ROM without going into the bootloader or recovery, which seems to be impossible.
Update problem solves if anyone gets this follow the guide below.
The solution was simple i followed the guide below and it bought my phone back from the dead.

Black screen bootloader and constant hard freezes

If I have my phone off, and power it on it will boot straight into the bootloader but have a black screen, if I press the powerbutton I assume I am choosing "resume poweron" because the phone restarts and then powers up with a black screen for 30 seconds before the animated part of the boot animation starts.
I have done a full reflash(afaik) from LOLINET using my device model file XT1926-5 and my region RETAPAC and when I reboot it still has the black screen.
I have Magisk installed and I believe my bootloader is unlocked, the only thing I remember doing was trying to flash TWRP but I have done a full restore since then using LOLINET.
Usually a black screen like this wouldn't be a problem, however the real annoyance is my phone constantly will freeze up for no reason, I will be mid way writing a message and the whole phone will hard freeze, I have tried doing another restore to see if this will fix it and alas it has not, so I am at a loss to what is going on, I have booted into TWRP and tried repairing partitons thinking something could be flipped and it was angry but no.
So I am a tad bit out of ideas unless anyone has anything for me? Logcat doesn't turn up anything interesting reguarding the crashes, I haven't found any events that are logged with ERROR,ASSERT or WARNING at the time of crash.
Anyone got something for me?

Are you able to get in recovery mode, or the bootloader just freeze.
If I try go to recovery it falls through tight away to the boot loader

Even if I use adb reboot recovery it just reboots into the black screen fastboot.
