What happened? Stuck in fastboot - LG V35 Questions & Answers

Phone seemed to get laggy after a couple weeks or so but a reboot fixes it. It got laggy today and I rebooted and now it's stuck in Fastboot mode. This is a ULM phone on rooted stock Pie.
Any ideas what to do? Anyway to get it back without wiping it?
Thanks!

[Q] Nexus 7 gets stuck booting. Tried reflashing stock OS multiple times.

I seem to have got myself into a bit of a pickle here.
I had a rooted N7 on 4.2.2. Tried to unroot (in lieu of going up to 4.3). Disaster struck! It wouldn't boot. It would just get stuck at the bootloader and go "Booting failed" or something similar.
So bother, I could get into the bootloader. So I tried to fastboot flash a stock image using this (http://forum.xda-developers.com/showthread.php?t=1907796) guide.
I got a bit further now, it would get the X loading screen but then no amount of waiting would have it boot.
So I tried factory reset from the recovery menu (the one with the Android and the red triangle).
No good, still did the same thing.
So I tried using Nexus Root Toolkit to flash stock + unroot from a soft-bricked/bootloop state. Nope! No good. Still does the same thing.
I've been through every combination of flashing, clearing, resetting but to no avail!
I've tried flashing CWM and TWRP but when I try to get into recovery mode, I just get the Google logo forever. This is a nightmare!
What's going on Have I managed to brick this thing...

Hey,
did you try doing all these manually :
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader.img
fastboot reboot-bootloader
fastboot -w update image.zip
PS : Edit these according to images you are trying to flash.
You mentioned you tried the guide but try this once again.
Unlock your bootloader / keep your bootloader unlocked while doing this.
If you want to you can even try running the .bat files and / or .sh files while in the bootloader.
If it still doesnt work , download the latest custom recovery and just try flashing it through
Code:
fastboot flash recovery recovery.img
Please mention the errors you have a bit more in detail during these steps !

Okay, I've managed to get TWRP up and running.
Now... how do I get a ROM onto there to try to flash? >_<
PS. I did all those commands manually many many times. It's got to a stage now where the X logo never actually comes up... Just the Google logo and the little padlock

Code:
adb sideload ROM.zip
in advance options > adb sideload
And about the ROM getting stuck at the Nexus boot animation , try getting a logcat.. maybe that will help. !

Amazing. I actually managed to flash a copy of Cyanogen on there and it all booted perfectly.
Now I wonder if I can get it back to stock from here easily..
Thanks

You can ... just make sure you have downloaded the right factory images and flash the use the .bat / .sh to flash the images .. keep in mind that you will lose all your data including that on the internal sd. All the best

So I tried to reflash a stock image... same issue again! Just freezing at the Google logo screen :/
Properly stumped as to why it's doing that. Maybe I'm stuck with Cyanogen...

So close...
Downloaded the new SDKs from Google and managed to actually flash and get into a stock version of Android... but it's constantly saying "Google keyboard has stopped working! Launcher has stopped working! etc" and it's practically useless
Gaaaaaaaaah

Okay my solution to this:
Just keep flashing it with the flash-all.bat command until it just... worked.
Must've done it about 15 times.
Well that's that ordeal over.

Nexus 4 stuck on boot screen after update

Need some help.
I just sideloaded the 4.3 update to phone and now it's stuck on the 'X' loading screen.
My phone was rooted, but all stock (including the bootloader). I used the sideload ADB command and everything went fine, but the phone now won't boot.
How do I fix this?
did you data wipe(factory reset) before flashing?? if not, you have too.
I applied the OTA...didn't think I had to
Any idea on how I fix it now?
Really don't want to lose all my data

Is there a way I can fix it without wiping everything?

I do not think because you have to change recovery you must unlock the bootloader and unlock bootloader wipe the phone

no, its the data(and other stuff) causing it not to boot. same thing when flashing custom rom, you wipe when fkashing different roms. and going from android 4.2.2 to 4.3, theres many changes, enough to consider it a different rom.
Shoot...I should have done more research before doing this.
I did a factory reset through the stock bootloader...but it's still looping on the 'X' screen.
Can someone walk me through this or point me to a guide?
Bootloader is currently unlocked and I'm able to get into the factory recovery.

Initially, I flashed the OTA zip.
I'm okay with just restoring everything back to factory at this point...
Try to restore using the factory image

yea, the zip youd want to wipe data/factory reset, then flash the rom. dirty flashing wont help since the changes are big enough.

I bought my ole lady a Nexus 4 for Valentines day, anyway, today she got the OTA update and let it install the update. Now mind you she is 100% stock, adb debugging was not enabled, and her bootloader was still locked. (She would not let me touch her Nexus 4 lol) When the device rebooted it stuck on Android Upgrading finishing boot. So I said well let me see what I can do, this is what I did to fix it.
I use only Ubuntu so this may not work on windows i do not know. I Booted the device to the bootloader, connected it to my laptop via USB. I opened a terminal and typed in "sudo fastboot devices" and entered my password when promted and this gave me the device ID and fastboot letting me know fastboot was working. I then typed in "sudo fastboot reboot" and the device rebooted but was stuck on the bootanimation. I opened the internal storage up on my laptop in my file explorer and made a copy of her internal storage. Next I booted the device back into the bootloader then opened a terminal and typed in "sudo fastboot oem unlock" and the device gave me the unlock warning and the yes or no options. I selected yes so it would factory reset. After it did the factory reset the device reboot and booted to the setup welcome screen. Hope this helps others, also thanks to my good good friend Ljjehl for reminding me to use "sudo".
Edit: If you open the command promt with Administrative permissions in Windows this will work in Windows as well. Go to C:\Windows\System32\cmd.exe and right click on the cmd.exe file and select run as administrator. Then CD to the location with your fastboot.exe command. Thanks to another good friend TheBr0ken.
Thanks for the help...
I just ended up flashing each of the 4.3 components from the factory image. Just annoyed that I lost everything...
I'm stuck at the same screen. I received the OTA update, I didn't do anything special. My phone is unlocked and rooted (or WAS) but that was months ago, the rest is stock.
I think having encryption on my phone may have made it do this. I don't think Google anticipated doing the update properly for encrypted phones. Now I fear I've lost everything because even if I could connect, all data is encrypted...
similar problem
After starting to OTA update it was going smoothly, i was making breakfast, came back to find my screen at the "starting apps" screen frozen. The little circle that rotated wasnt doing anything so i left it there for awhile longer and still nothing. It would not move off that screen so i held power button down and restarted. now its stuck at the X screen also.
Yeah, I'm stuck there too. Already tried Factory Rest, didn't work. So what can I do?
I was on stock 4.2.2 and unrooted. I used the 'Google Services Framework' hack to force the 4.3 OTA update. The update downloaded successfully, phone restarted to apply the update and then restarted again. And now its stuck at the Google screen and keeps on restarting :crying:
I dont have the USB drivers installed on my PC too.
Same Problem
I have a nexus 4 (stock and unrooted),after 4.3 update,it is lagging during phone lock on/off (2 sec/5 sec).Hence I restarted my phone,and it stuck at "x" logo.Did clean data 3 times and then its working.
The problem is,in 2 days,I have experienced and done above thrice?
What could have gone wrong?
Hi guys,
I've just found how to correct this problem. All you have to do is to correctly wipe your phone before flashing factory image.
So :
Fastboot erase boot
Fastboot erase recovery
Fastboot format cache
Fastboot format system
Fastboot format userdata
I've just unbrick a n4 this way 15 minutes ago.
I have found the problem in recovery where you can see error log saying "cannot mount cache"
So formating correct the issue.
Hope it can help, fingers crossed.

Unlocking problems? Boot loop? Help please!

I rooted my oneplus 2 some time ago to install the Screencast.app that there was on the oneplus one. I then after a while noticed that it started to perform worse than before i rooted it, so i decided to try to unroot it to fix the performance. But when i rebooted to fastboot and tried to flash the stock recovery, it said that the bootloader was locked. I then tried doing the unlock command (fastboot oem unlock), and it seemed to work (although - it didnt - in cmd it said finish but when i booted into bootloader again it was still locked) but when my phone tried to reboot, there was i quick flash of the oneplus logo and then the screen went blank. When i tried turning it off, i just rebooted and did the same thing. I could not boot into recovery either. The only thing i could do was booting into fastboot and from there i managed to use the command fastboot continue and restart my phone properly. So now i cant use my recovery to factory reset, i cant install a new recovery because the bootloader is locked, and now every time my phones powers off, i have to do the same thing with booting into fastboot and do the fastboot continue command to start it.
Can anyone tell me what the issues is here and how i can solve it?
I have the same problem, but once I got the phone to boot, I did a factory reset. Now I'm unable to even boot, literally the only thing that works is fastboot.

Phone seems dead

Hello,
I get an infinite bootloop with my phone, to boot it i did, fastboot reboot-bootloader and fastboot-continue. That worked fine, then i did a firmware update (i was on stock rom, but rooted), then my phone is still doing a bootlop, i tried everything but i now i am not able to detect it in fastboot, so i can't boot my phone in normal mode, and in recovery mode. The only things i get is fastboot but undetectable :/
I would like to know what to do for getting my phone resetted to a cyannogenmod rom.
Regards.
Check drivers... Than you 1st aid ( general forum thread )

Did you check your Volume Buttons? Had this Problem with a friends OPO where the Volume Button was bent and so the Phone only booted to Fastboot.

Stuck in a sort of bootloop after flashing factory android 4.2.2

So after booting up the phone after a few months, it only booted into the recovery and couldn't get into the system, so I decided to flash the factory android, but after flashing it using the included flash-all bat file, this is happening:
youtu(dot)be/P24gyQDcx98 .
So any ideas how to fix it? At this point I'm only able to get into the fastboot mode.
