For debugging purposes, I need to know if there is any difference in meaning between the bootloader just freezing while the tux icon is shown and it vibrating 5 time a few seconds after the tux icon has appeared and then rebooting to recovery? Is it possible to get any information from this behaviour? Furthermore, are any logs made during boot?

Hello people,
I have a German Nexus 4 and it gets stuck in bootloop whenever I turn the power on.
I've had issues with the phone since the last few months - i.e. random reboots, random program crashes.
But recently I tried to root it in order to install the Android L developer preview. It was during the booting process, when my Nexus crashed and it has been unable to boot ever since.
When I push all three buttons (power + 2 volume rocker buttons) simultaneously, I get the fastboot screen.
Choosing the following options has these effects:
Start --> phone tries to boot but gets stuck in bootloop forever and ever
Restart bootloader --> restarts the fastboot screen
Recovery mode --> phone shows the robot with an opened belly and a red warning sign (see photograph)*
Power Off --> turns the power off
Also, it is NOT detected or recognized by my Macbook when I connect the Nexus via USB cable. So it's impossible for me to access the phone via my Macbook.
*This is the screen shown when I try to go into Recovery mode in fastboot:
[can't upload outside link to image]
So this leaves me with no options as I never get further than the 4 turning circles forever and ever.
Is my Nexus 4 broken or is there still a chance to unbrick it? (I have a MacBook, so Windows programs won't work for me)
Of course it's not possible to recognize it when OS is not running.
Download WugFresh toolkit, ADB drivers (Universal) and the factory image. Enter fastboot, connect USB and flash the image
Your phone is not hardbricked, because it boots into the bootloader.
It might be recovered if you can access it with fastboot.
Try uninstalling all related drivers and install the Naked Universal Driver.
Thanks for your replies!
Unfortunately, the programs you mentionned don't work on my Mac (they seem to be Windows-only).
Also, how can I install stuff on my Nexus? Since it is not recognized by my MacBook, I can't load any files onto my Nexus.
And since any command on the fastboot screen only leads to the phone powered off, restart of the fastboot screen or the mentionned bootloop, I cannot perform any actions on the Nexus ...
Go to a friend with Windows.
Problem solved!
Somehow after the 1000th bootloop I finally reached the screen where I could wipe the phone.
And then it finally booted! Now all the data are lost and it's like a new phone, but at least it's working again!
How long was the boot loop? Was it the new boot animation from L?
Because when you flash L, the first boot up may take up to 15 minutes, leading you into thinking it's a boot loop.
I might have bricked my LG G2.
Here is everything I did:
-I rooted the phone with the IO root kit
-wanted to installed a recovery so I installed TWRP manager
-applied SD card patch
-tried to install recovery with TWRP manager several times but app always crashed
-installed SDK on the PC
-started adb and executed "adb reboot bootloader"
the phone got a backlight screen and hasnt been reacting so far.
When I held the power button the screen went black but sometimes the backlight appeard again. I don't know how to reproduce the backlight though.
adb can't detect the phone when connected to the PC.
As soon as I plug it in dozens of Partitions show up. Windows show an error message for each of these partitions. It says I have to format the volumes to use them.
After testing I realized that everytime i long-press the power button for a few seconds the windows errors start popping up.
When i long pressed the power button for 30+ seconds to completely shut it down the notification LED started blinking red 8 times in roughly second intervals. then there was a short break and the 8 blinks repeated.
Thank you for all help, it would suck to have a 1 day old phone broke...
You probably chose the wrong device in TWRP Manager. Choosing the wrong device can easily lead to a brick because TWRP Manager may attempt to flash to the wrong partition. The G2 does not have a TWRP Manager flash available due to loki, so you couldn't have chosen the right device.
Almost have the same problem... the only difference is my black screen is blinking continuously while it is connected to the mac... Seems like it tries to boot but gets blocked and retries in a loop. Tried around now for two evenings without any progress...
Anybody who can help?
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.

So I wanted to root my phone (P9 Lite with Nougat). It was my first time so I found a step by step tutorial and used it to progress. After a load of time I finally was able to unlock it, then apparently, I was supposed to install TWRP. Failed a few times then I understood that TWRP version was for marshmallow, so I searched for a version compatible with nougat. Found one, installed correctly, file was transferred. Anyways when I tried to boot TWRP it would not work, it would boot in normal mode. I tried 2 more versions TWRP and it was the same. All that Power button + one of volume buttons **** was not working. So I thought, maybe I just overdone it, with many different versions of TWRP. So I decided to factory reset it. I rebooted my phone, now it is stuck at 'Your device is booting now' and I am frustrated as f**k. Not mentioning problems with unlocking, this whole process was really annoying, been doing this **** for 4 hours straight. Would like to receive some help if anyone got some. Let me know if there is something more you need to know.
Thanks in advance.
EDIT: Tried reinstalling img failes and relocking bootloader using https://forum.xda-developers.com/hu...i-p9-lite-stuck-device-booting-t3539696/page4
Now the phone is stuck at ERROR MODE, Attention! Please update system again
Error!
Func NO: 11 (recovery image)
Func NO: 2 (load failed!)
Bump.
I honestly need help guys. I let battery die, then I use Minimal ADB and FastBoot + (volume down + connecting to pc via usb), phone would start and load system normally to the point where it requires PIN lock. Then it notifies battery is too low and shuts down. After charging 2-4 mins phone starts itself again, with same error screen.
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.
