Device is stock, unrooted, locked bootloader. The OTA update took a really reeeeeaaaallly long time and eventually upon reboot it got stuck on the "Android is optimizing apps" screen. The loading circle at that point was frozen and no longer animated. After an hour or so, I did a long press on the power button and it never booted normally again.
I put it in fastboot mode and tried all the usual steps, erased everything, but it failed on "bootloader locked." Tried to unlock the bootloader and it told me to buzz off (i.e. "FAILED - unknown error"). It won't flash recovery either and the stock recovery gives me the dead Android with the red triangle and "No Command."
Tried the Nexus tool kit and same deal.
The bootloader version is now 4.18 instead of 4.13.
So this thing is an ex-Nexus, right? Is there anything else I could do?

I did an OTA update of Lollipop on my nexus 4, it got stuck on the 'installing system update' for about an hour, so I tried to restart the phone and it loaded the new lollipop animation, but got stuck there for 20 minutes, so i restarted it and it still didn't want to load into Lollipop, so I went into the bootloader and hit recovery and it came up with 'installing system update' again and still gets stuck. when i'm in the recovery, it won't recgonise vol + and power button press to do a factory reset, it just does nothing. my computer also doesn't recgonise the device... is there anything I can do?
Thanks!
Start into bootloader and try to flash the factory image via fastboot.
boot to fastboot and flash a custom recovery. you can use twrp or cwm to do a standard factory reset and you should be fine.
Ok- I need some help. If anyone cares to comment or point me in any direction it would be greatly appreciated.
TL;DR - tried to flash stock image and it still doesn't work.
My phone basically committed suicide last week for no apparent reason. No physical damage with the device that I am aware of so I presume it is just soft bricked. I attempted the usual clear/wipe cache and the stock recovery factory reset to no avail.
After turning it on it will just be stuck at the red Motorola "M" logo. Right before it got put in this boot loop a few system apps crashed so I rebooted (Google Play, Google Chrome), and the phone never came back up.
I do not have root, nor an unlocked boot loader, which seems to be why I can't load any custom recovery stuff (tried fastbooting the Clockwork Recovery image).
I've attempted to flash the stock image (VZW_XT907_4.4.2-KDA20.62-15.1_CFC_1FF.xml.zip) from sd_shadow's stickied post[1]. According to RSD lite the flash is successful, but its still stuck in the boot loop
One thing I noticed is that the AP Fastboot screen doesn't actually print out anything other than "usb connected" during/after flashing. I would think it should print some diagnostics, or at least a success message. I'm suspicious because the AP Fastboot screen will print security or sizing error messages when it fails.
flashboot screen reads:

Same issue. Did you find any way to fix it ?

Nope, and my guess is I would need the bootloader unlocked to get any further. The Razr M doesn't show up on this list so I'm not even going to bother

any Motorola with Droid in the name, and Verizon on it, will not have an official unlock option
Sent from my XT1080 using XDA Labs
Hello everyone!
A friend asked me if I could try to solve his cell´s problem.
The phone is a SM-G928G and when it boots you get the "installing system update" blue screen, then it shows a yellow triangle with an exclamation mark in the middle and then it boots into the stock recovery.
I can´t boot into download mode, either with the "reboot to bootloader" option or via the buttons (vol-, home, pwr). Anything I tried gets the same result. I tried to ADB sideload a different ROM or recovery but I always get the "wrong footer" message.
If you know a way to make it work I´d be very grateful.
Thanks
As the title says I tried to root my phone and got into this situation. I followed a video from TheUnlockr
I put my phone into developer mode and the OEM unlock.
I completed the Odin3 boot img using Samsung_G935x_QC_Rooted_BOOT.TAR file that I got from XDA developers. It said it passed
Afterwords I'm stuck in the reboot loop. I can get into the the teal custom OS download screen as well as the recovery booting screen that does the "Installing system update" animation and I get a "No Command" screen with a dead Android, after a bit it lets me into the Android Recovery screen. I've tried Reboot system now, no go, reboot to bootloader no joy that goes to the "Downloading... Do not turn off target" message.
I believe my bootloader got gorked with the rooted boot.
How can I get back to just a usable OS? I've downloaded the stock firmware from Sammobile but that's taking 2-3 hours. Am I just until that finishes downloading?
Yeah, wait until file finishes and than of course flash with odin. Sometimes Sammobile is slow, you may try downloading firmware from uptodato.com (if you've fast internet connection).
"your device software cannot be checked for corruption" after installing twrp, help!!
Hello, as title says, following oem unlock procedure, i flashed twrp using fasboot however i could never boot it and now when i try to go to fastboot mode and/or reboot, i see this message "your device software cannot be checked for corruption[...] please lock bootloader"!! Dunno what to do? Please help!
Easy: do absolutely nothing, this is intended behaviour. Unlocking the bootloader leads to the displaying of this message on boot up. Just LG's way of saying continue at your own risk.
Ok so they're even more annoying than samsung..! Anyway, my problem is : how do i enter TWRP..? I flashed again, successfully.. Then i dunno how to enter it!
"The stock recovery appears but you have to select the factory reset option and it will boot into TWRP" i read this. Well it's wrong. Doing so just launch the factory reset!
This video https://www.youtube.com/watch?v=MR4DTgTxhGI shows phone reboots to TWRP after entering "fastboot reboot" (once recovery was flash) : here it just reboots normally!
"Finally Type “fastboot boot TWRP-Recovery-filename.img” to boot your LG G6 into TWRP Recovery" well i thought about that and tried it :
D:\Android\ADB&Fastboot>fastboot boot recovery.img
downloading 'boot.img'...
OKAY [ 0.901s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.925s
I'm very disapointed so far, i expected the G6 to be easier to handle the S7 but it's a pain even before i start using it.. Hell!!
It seems to me that you didn't boot into twrp immediately after flashing it via fastboot. Afaik it's important that you don't boot into OS after flashing, otherwise twrp will be overwritten with stock recovery. I had the same problem when I did the procedure.
The only way I got it to work was booting into twrp via button combo immediately after flash (you know - keep pushing power and vol- until Lg G6 logo appears, release only power and immediately push it again, keep 'em pushed until factory reset, confirm twice and it should boot into twrp). Once you've booted into twrp directly after flashing, it should stick.

After doing this, for TWRP to stick, you have to flash a custom rom, or delete the system/bin/install-recovery.sh to prevent stock recovery overtwrite
