[ROM]IO fastboot for retail unlocked bootloader
You should be able to get into recovery using rom manager or quick boot.
NVFLASH>stock recovery and than apply [stock][eur] rom via update.zip! (the best part of the rom is a neat recovery and download mode selector with the power and left vol key combo) For instructions:

[HELP}Nexus 4 Recovery Mode Issue

Alright guys this is pretty frustrating and scaring me completely.
I unlocked the bootloader no problem. Then I wanted to flash TWRP recovery by typing in this command "fastboot flash recovery openrecovery-twrp-2.3.2.3-mako.img" so I could root.
Then when I rebooted into bootloader mode and selected recovery I got the Android laying down with the red triangle exclamation mark.
So I downloaded the Nexus 4's factory image and re-flashed the stock recovery by typing fastboot flash recovery recovery.img and the same thing happens.
I even tried booting into stock recovery by typing fastboot boot recovery recovery.img and the same thing.
Any help will be appreciated and its urgent lol.
EDIT: FIXED! Forgot to type in fastboot erase cache after flashing TWRP. Not sure if it was required but I did and all is well now.
Thanks again guys
Thanks
Edit: Another issue - I installed CWM SuperSu v0.98 via TWRP and I hit reboot. Now I see the Google logo for a while. Then the Nexus logo. It doesn't boot into the actual phone. Still stuck on the Nexus logo. Any takes folks?
The android laying down with the red triangle is the stock recovery. You usually press volume up when on that screen to get stock recovery options.

Ya but even before when I flashed TWRP, I couldn't even get to TWRP. I went to the bootloader mode. Pressed the vol keys till I got to Recovery.Then I pressed the power button to select it and that's when I got the red triangle with the Android laying down both on stock and TWRP recoveries even when booting into the recovery vs flashing.

Hmm sounds like the same boot loader problem I had with the nexus 7 and it was fixed with the 4.1.2 update
Try flashing cwm recovery I normally don't use TWRP because I never really liked it too much but see if that works.
Okay so I was able to boot temporarily into TWRP by typing fastboot boot openrecovery-twrp-2.3.2.3-mako.img. Now I'll see if I can flash it... and try booting into recovery mode.People on the Nexus 4 Dev threads and on the Paranoid Android threads recommended TWRP since it works properly with Android 4.2 vs CWM and they said TWRP is a step better.
Mods please lock thread. Thanks

Could you please be more specific on how did you fix it?
I've got my N4 maybe a month ago, I installed the 4.2.2 OTA as soon as I got it, the I proceeded to unlock it and root it, one day someone recommended to clear the cache of the phone using the stock recovery (which I thought I had / to fix another problem that I was having) I went to fastboot and tried to access recovery, BOOM, just an android laying down with a red exclamation mark, no "no command" error at all. I downloaded CWM touch and flashed it using Nexus Root Toolkit, that worked fine, but I didn't want a custom recovery and also I needed to fix a 3G latency problem that I was having, after some reading I saw that someone recommended a full flash using the stock google image.
A couple of days I proceeded to flash the factory image, I installed it, after that I did a factory reset from android itself. After doing all that I wanted to clear the cache with the stock recovery just in case, BOOM, an an android laying down with a red exclamation mark and this time with a "no command" error. Tried the trick of holding the power and pressing the volume up, NOTHING HAPPENS!
Right now I am using CWM Touch.
Any suggestion?
Thank you.

Same thing with my phone. I flashed a custom recovery but cannot get into it. By pressing recovery mode from the bootloader, it just displays an android laying down with „!”.

Stock Lollipop boot issue

Hi,
I've decided to return to stock after using Cyanogenmod for quite a while. I used fastboot to install the stock ROM from the google developers site, but I'm getting stuck at the boot animation stage.
Others have said to lock the bootloader, but it still isn't booting.
I've tried to go into recovery, but I get an android lying on his bag with a warning triangle. Prior to this, I had ClockWorkMod recovery installed.
I've installed TWRP and that's functioning but has anyone any idea on how to get past the boot animation?
thanks

Boot into the stock recovery and do a factory reset. The dead android is the stock recovery. When you get there push vol up and the power key

please help ive bricked my phone :(

i have note3 n900
i rooted my device and installed twrp
then i wanted to add 3 dots menu to my stock touchwiz 5.0
i followed instructions in that thread:http://forum.xda-developers.com/galaxy-note-3/themes-apps/mod-tredots-overlay-menu-note-3-t3006924/
then my device stuck at samsung logo
i waited 10 minutes then pulled the battery
but here the surprise that the power button dont work ever even when try to open recovery mode
its only work when open download mode
and from there i can reboot and turn on the device.
i tried to install recovery again but when boot it stuck at black screen
please help :crying:
When I have bricked a device I either use a computer and adb. You could also use a rootkit . Which is just a graphical adb interface. The idea being - return to stock. If you get there with root and custom recovery - back up. You can then start again with what you are trying to do. I know with the Nexus 6p the Nexus root software saved me.

Then flash your stock rom via odin.
If the phone gets stuck again after flashing a stock ROM, boot into stock recovery and perform a factory wipe.
thanks guys it worked after flashing firmware throght odin

Boot Loop on Galaxy S7 Edge

Hi all, so after trying to get rid of the FRP on my Galaxy S7 with Odin, I essentially bricked my phone and now it is stuck on a boot loop at first it was with the Samsung Logo screen, but I decided to screw up even more and now it is stuck on a boot loop that only displays "RECOVERY BOOTING" unable to get into the recovery it just sits there with the blue letters popping up. The files that I ended up flashing that bricked my phone were within this following thread just for reference. I was confused on what images to flash so I ended up flashing two of them a custom BOOT image and a RECOVERY image. Unable to succeed as the phone ended up on a boot loop. Any help is welcome. Thanks.

Try to reach odin download mode
Restart your phone using power home vol down and keep holding it until you reach the bootloader.
Hit OK to reach odin and flash Twrp version 3.2.2.0 hero2lte version.
Using odin 3.13 tick the ap box and flash the twrp recovery version 3.2.2.0 by pressing start.
Reach recovery by force starting power home vol down then immediately holding power home vol up to reach twrp.
even if you can't reach twrp you should be able to flash an official stock android os using the ap box in odin.
If your having bootloops it helps to flash only 1 check box at a time.
In short flash stock firmware then enable the oem unlock in developers options to disable the frp lock.
