LG G4 H815 - Optimizing Apps & Reboot after build.prop edit. Bootloop? - G4 Q&A, Help & Troubleshooting

Hey,
I have a LG G4 H815, rooted, bootloader unlocked everytime I boot my phone it optimize apps, reboot, optimize apps, reboot, optimize apps reboot... Before this happend I edited the following line in **build.prop**:
persist.splitwindow.support_all=false to
persist.splitwindow.support_all=true
Okay, I did a hardware reset by pressing volume down and power button, but nothing happens. Unfortunately it don't even shows TWRP. It still says optimizing app 1 from 100. Is there a way to delete all apps and do a full hard reset? Will LG repair my phone? My PC don't recognize my phone. I am not able to answer on this topic until 27.02, because I am not home. I hope somebody got an idea. Thanks.

G pro, spyware

To start off,
i would like to say im not some kind of paranoid freak who thinks the gov or ordinary people around me is spying on me.. lol
Im fairly new to this android world, and got this phone, less than a month ago. from a ... doubtful friend.
The phone always booted twice on startup, and it installed apps with out telling me like "Muted camera".,,which i caught probally by rebooting the
phone right after reset. and a error popping up, that the install file was invalid.
I rooted it (I think.. I rooted it.. or could be PRE rooted. Never checked) ,
checked system but couldn't find out anything useful..
i deleted all the dalek? cache and factory reset, formatted external sd in cwm
but still.. freaked out when i found out that my personal files.. such as photos videos were still present (was on the internal memory)
the external, was formatted..
so i got the lg firmware update on pc
put the kdz file,
settings were:
3g QCT & mode was CS emergency
ran it in Download mode.
Still.. this seemed to only reset the system settings..
the phone itself wasn't wiped..
However, after i reset it with kdz file
The security? error of some sort popping up between the two reboot, was gone. however the two reboot was still present,.
Before;
Turn on phone => security error, (in terminal typed ..interface with black background) => phone shutdown => boot again automatically => LG logo => turn on
After the kdz file recovery:
Turn on phone => Lg logo => phone off => on again automatically with lg logo => lg boot animation and normal booting
Now, my ram and battery usage is still abnormal.
resetted the phone in software os level, (in settings)
Nothing.. seems to help
any.. suggestions?;;

[Q] How can I update the software?

Hi all,
I am trying to update my 10.1 tab 3 device through the relevant entry in settings, but I get an error about my "device is modified".
I hard reseted the device, and I am still getting the same error. What can be happening?
Maybe you have root your tablet or install new recovery ?
Press and hold power, home, and volume down. You will see a warning screen then press volume up to enter Odin mode on the tablet and check the binary number. If its not 0 your device is modified and you can't update it. You must restore the original Samsung firmware without Root or something else on your device.
No, I have not rooted my tablet. I have only isntalled a few apps from the play store.
I tried to hard reset a few times without any success. I think that erasing everything from the sd card, solved the problem (after a hard reset).
I don't know why, and which app has placed what on the sd card.
I had really few apps, kindle, skype, oasvn, and some apps related to night sky maps. And the official vnc viewer app.

LG G4 half-bricked / full unusable

Hi everybody !
I usually (always normally) succeed myself at resolve my phone problems, but this time I can't do anything.
My problem :
I have a LG G4 ; I saw an update of Imperium Rom (v8) this morning, so I installed it, everything worked well until I decided to install a, apparently, ****ed mod on xposed ; and since I have rebooted I can't do anything ; the LG logo shows and just after "UI system as stopped", just one time but, then I can't do anything, screens over screens, can't access parameters, password required, "flex mode" (never saw this before), re-password, system UI restart, loading background, restart system UI; and this in a infinite loop SOOOOO
I decided to reset it, yeah... But I can't access my recovery, wow o/
I followed the step to access it by switch it off and press volume down etc --> It just boot normally, or best in safe mode by magic but same problem ; via parameters but I can't access parameters ; and via ADB buuut my phone isn't recognized even with the complete sdk, drivers, everything you want, there's nothing to do because --> while restarting system UI it deconnects so of course it can be recognized
I removed xposed (while I could still access recovery, as I was thinking it was coming from the xposed module) and so now I can't even access recovery via shutdown menu (as I had put "reboot to recovery" in via Xblast, a xposed module) ; and of course it doesn't change anything
I neeeeed your help so much, I don't mind losing what's on it :crying:

Please ensure you REALLY use the correct key combo! Just saying bla does not tell us what exactly you tried.
If you really can't get in you can try to Boot into download mode

Then use lgup to reinstall stock ROM and do all the stuff again to get twrp, root and a custom ROM.

Thank for your answer ! No it couldn't even boot in download mode
I resolved my problem by forcing again the buttons to reset completely, it finally showed me after about 30 boots or more the reset screen, I said "ok" ; and in fact it just rebooted saying "updating Android", I did not lost anything.
I still don't understand how it happened but anyway !
I don't know if it's possible to set the topic as resolved ? I don't find it

[HELP] "Android system has sttoped working" loop 2 seconds, unable to use screen.

[HELP] "Android system has sttoped working" loop 2 seconds, unable to use screen.
Hello,
Lg g3 (Telefónica / Movistar branded Spanish carrier)
Bought in Jul 2014.
Weeks having reset problems, one day, on a reset, got the msg "Android system stopped working", close, 2 seconds, again same msg, I can't use ths screen to avoid it, just to close the msg window, neither to browse options in those 2 seconds in each loop. I can only use the turn on/off buton, so, when I reset, same stuff again..
I tried to use Recovery Mode (vol-) and I just get the option to restore and WIPE ALL INFO (even files, pics, etc..)... no more options
Tried Lg Suite + Download mode (I can enter in download mode) but the software don't recognice the device.... using original cable,
I need the stuff inside, don't care about the phone thou, will get a new one, but I really need the info inside (no SD, the info inside the internal storage).
Any help?
If you turn off the device, hold down power and volume down. Release them when the lg logo shows then immediately press them again you should get to a factory reset screen. Try performing a factory reset, this will not wipe your files, just all apps and app data
Hi,
thanks for the answer.
that was my first hint, but, as you can see ( imgur.com/ d31OXJi) that menu option says "Delete all user data (including LG and carrier apps) and reset all settings?"..
I do belive this is warning me about wipe all my data including pics, videos, contacts, etc...
Are you 100% sure that wthis will not wipe the entire information?¿
Thanks...
BUMP!
Can anyone help me or confirm us if I do the vol down restart to factory will wipe my pics away??
Thanks...
Really? Noone ever have restored the phone using this option on a g3 to know if the pics will be deleted or not? amazing...

Factory Hard Reset Not Proceeding (Fixing from a bootloop, data partition need wipe)

Hey guys, I'm using a stock L-01E (Just a JPN E975), when it heated up one day. Tried to turn it back on, but would only bootloop. Saw the guide here for bootloops (https://forum.xda-developers.com/showthread.php?t=2010624), and got until step 7. Now with a bootloop still occuring, I went and used the hardware buttons to go to the factory hard reset. Got in, selected to continue, but after confirming, it has been stuck on that screen for hours. All other videos I've seen had the device turning its screen off seconds after confirming. Can anyone help me? I really am in great need.
That's old method use this it's better.

Unfortunately, I just completed it using that method, but am still encountering bootloops. Should I set it to CSE?

Thanks. So going with CSE, the tool gets up to 98%, and the phone restarts, as it should. Problem is, the phone keeps bootlooping, and the tool says that the upgrade stopped due to an error. I checked the link you sent, and some people had the same issue, but no solutions were given. I'm not quite sure what to do with this now.
Master reset with hardware keys
A master reset restores the original factory settings and may delete your personal data on the internal storage, such as downloads, ringtones, images, apps, contacts, and Visual Voicemail. It does not delete data stored on the SIM card or SD card.
If the device menus are frozen or unresponsive, you can master reset using hardware keys.
Back up data on the internal memory.
Power off the device and ensure it is not connected to any USB cables.
At the same time, press and hold the following keys for 8 seconds:
Power key
Volume down key
When the LG Logo is displayed, release the Power key and then immediately re-hold the Power key.
When the 'Factory data reset' screen displays, release the both keys.
Use the volume keys to select yes, use the power key to confirm.
Re-confirm by using the volume keys to select and power key to confirm.
