I've had that a few times. Clearing the cache always fixed it for me. The only reliable method that worked for me was
Turn off your phone
Hold the power and volume up buttons
When the phone vibrates, release the power button
That will get you into pre-recovery where you can use fastboot. You need to have fastboot functional on your PC/laptop/device first, then you can connect the phone via USB and run
Code:
fastboot erase cache
It should only take a couple of seconds and when you reboot it should work fine.

Hi, thanks for the reply. However, immediately i plug in the usb cord to the system, my phone changes from
FASTBOOT CMD WAITING
To
RESULT: FAIL(unknown command)

I always had the USB cable connected before rebooting so I have never seen that message before. You should still be able to run the fastboot command regardless of the error. IIRC it'll say RESULT: OK if it works.

Need HELP! LauncherPro error rendered my phone useless

Hey everyone, I need some serious help with my phone!
I have launcherPro, but today I started my phone and suddenly I get this error saying that LauncherPro has been unexpectably terminated and that android.process.acore stopped working. I don't know what to do, because it just keeps popping up and I can't do anything with the phone.
I also don't have the 3 keys combo.. I tried to reboot, take out batery, take out SD/SIM card, please I don'T know what to do!
Is there anything I can maybe deleted while my phone is connected to PC? Also, I have USB debugging off atm and I cannot go to menu so I can't use ADB to boot to recovery
Any help is appreciated.
P.S. Since I didn't do any flashing or anything out of the ordinary, I didn't use the 3 button combo fix..
i had the same problem
just hit the 3 button Recovery Mode
then select wipe data
reboot
fixed

Will this completely wipe out all apps and things when done?

yes it wipes out all user data
there's always the heat trick for the non 3 buttons capable
if all else fail go back to the store and have them exchange the phone
I had this problem on my old Hero and only a wipe solved it. Incidentally, it wasn't a LauncherPro issue, more a general Android problem.
if you had adbd (debug mode) running you can start any program (e.g. twlauncher) and therefore easily recover your phone. otherwise i would return the phone ...
I would say, get yourself a hairdryer... Heat the phone up untill it's scary hot... And then try the 3button combo.
If that fails you should rerurn it, as this wasn't your fault at all.

Try to go into recovery. Turn off your phone and turn your phone on with the power button + vol down. When the phone turns on,let go and press the same combo buttons again for a few seconds until it shows a factory reset. Click yes for both ( no it won't delete your data) and it will take you to TWRP
ןIt's still not working and I tried it yesterday and now it does not work because it is installed on the device Recovery So how do I solve this problem please help me!
Thanks in advance.

Phone Not Booting Properly

I have a rooted One M8 here with a custom ROM and recovery that I have been trying to boot into recovery however every time I try the phone seems to crash, turn of and then won't boot. After about 15, 20 minutes the phone boots up again by itself. Anyone else ran into this problem before or any advice on a solution? Thanks.
You can get to bootloader okay?
If so, go into fastbootmode (connected to computer) and fastboot erase cache, and try installing TWRP again.

That didn't work.. Tried booting into recovery and wiping the data and re-flashing the ROM but no luck.

So what exactly worked, and what didn't? The way you've typed it, I can't tell:
You can boot into bootloader?
You were able to flash recovery?
You are able to get into recovery?
The ROM flashed successfully?
But then it failed to boot?
Also, what ROM?
What version TWRP (version number)?
Try another ROM. Be sure to do the default TWRP wipe (data, cache, Dalvik) before flashing ROM.
I can boot into the bootloader and into the system it's self but it takes maybe 15 to 20 minutes everytime the phone is turned of to start back up again and begin booting.
I'm not sure what version TWRP is as it been months since I flashed it and I can't check because I'm waiting on the phone to boot again.

So do I have this right: The phone turns itself off, will stay off 15-20 min; during which time you can't do anything until it starts to reboot itself?
What happens if you hold power button, or power + vol up for a minute or more? Do either of these force it to start booting, or no response until it boot on its own (15-20 min).

I don't think there is one to force it to power off, I think there's only one to force it to reboot which is POWER + VOL DOWN (held down for a few seconds) on the A5, it's probably the same on the A3. Then immediately as the screen turns off you have to switch to the key combination for download mode or recovery. If if you just release the keys it will try and boot normally.

thx!! im in download mode now
Im in Recovery now. When i try to wipe it says it cant mount /data, /cache, etc.
Also Restore doesnt work because of this. I tried to Repair. System seems to be repaired, but /data fails to repair. Also unable to repair cache.
What to do?
(needless to say i first flashed the correct Recovery )
In Windows Explorer i see only external sd
Somehow i seemed to fix /data en /system. But not cache and dalvik.
I restored a nandroid backup and it boots until LOS animation now. But there its stuck. (but at least i passed Android logo now)
Installation passed pretty good, only in the end it said cache wasnt mounted.
Any ideas?
alright no clue how but its fixed now lol

Help!

So, I was on /e/ os, and I wanted to switch to lineageos, so I downloaded the zip, flashed TWRP (as recovery) went into it, flashed los, rebooted, got to boot screen, and right as it was about to go into setup, it turned off. I tried again, same thing, etc etc. I tried to go into fastboot and recovery, nothing. It's stuck at the Recovery mode... loading... then it has purple led at the top. it is the canadian h812 version.

Hi. I don't know exactly what the problem is and how to solve it. I would wait for an answer steadfasterX, or someone who knows the exact answer.
I would try to do this, but as I wrote above, I do not know if it will help or not:
Factory reset hardware key combo (https://forum.xda-developers.com/t/unlock-unofficial-g4-unlock-any-lg-g4-device-with-usu.3760451/)
As written above the regular key combo to get into the LG factory reset screen changes a bit:
power off device
disconnect any usb cable from the device
press volume UP + power button and KEEP THEM BOTH pressed until you see the LG logo the first time! THEN you have to immediately release the power button (ONLY that) and press and keep holding the power button directly again! Keep them pressed until you see the white LG factory reset screen
After that, I would try to go into the recovery, to format and restore or reflash.
Hope this helps. But it is better to wait for the answer of the knowledgeable. Good luck!

It worked... I hope the factory reset actually fixes it. (by it worked I mean I got into it)
Nope. Didn't work. It freezes up and says 'Secure booting error :1003' MODIFIED!' with a purpleish pinkish led.
Boot in fastboot and execute:
fastboot format userdata
(this will erase all internal data, pics, apps etc)
Then let it boot.
