Can't enter Recovery mode. System boots. Automatically enters download mode - G3 Q&A, Help & Troubleshooting

LG G3 D855
aoscp 5.1 Funnelcake
3GB/32GB
Android 8.1
No Root
No Custom Kernel
I had TWRP installed for about 2 years
But now when I try to enter it then it says "Boot Verification Failed" and then Blue and Red light flashes constantly until I pull out the battery. I even flashed MR_Bump on every ROM Flash.
Fact is,
The system boots up fine.
In rare cases the system boots up till the Launcher's home screen and then automatically reboots into download mode, but it can be easily fixed by a battery pullout.
My real problem is how to install TWRP once again because I want to install a new ROM because this one's malfunctioning.
Any help would be appreciated

Black Screen, Unable to boot after CM12 installation

I decided to install Cyanogenmod 12 on my LG G3. Everything went fine until the point of configuring apps and he final reboot. The screen went totally black. I tried rebooting normallly and rebooting into recovery but there was no boot animation or the LED did not even flash. I tried charging the phone but the still doesn't want to boot. I tried to install the stock firmware through download mode by pressing the volume up and plugging the phone into a PC, but I am even unable to go into download mode. If its like the phone's battery is not working but I do not think its battery since it happened at the moment when I installed CM12, unless it was an extreme couincidence. Thank you for your help!
What variant do you have, and what did you install? (D855?) Also try removing the battery and then powering it back up.

MM 6.0.1 Xposed Update!

So, i recently have tried flashing Xposed on the MM 6.0.1 on G920P a.k.a Sprint S6
( ALL_SPT_G920PVPU3CPB6_G920PSPT3CPB6_CL7280193_QB8664149_REV02_user_low_ship.tar )
I have root and recovery, but Xposed doesnt seem to comply with me.
from multiple sources or builds.
And each Xposed file that i've tried so far that i've been flashing over and over again, rinse and repeat.
( Flash Stock through Odin, Go through setup process on the phone, Reboot Back to Download mode to Flash TWRP, Reboot, Back to TWRP to Flash Xposed, Once flashed i Restart it again, back to the s6 screen to becoming a black screen bootloop, thus having me restart the whole flashing process again )
from android file host website. And Default xda unofficialy build on this website.
xposed-v79-sdk23-arm64-by-romracer-20151218
xposed-v80.0-sdk23-arm64-custom-build-by-wanam-20160211 - ABDYASAR 7.8MB
xposed-v80.0-sdk23-arm64-custom-build-by-wanam-20160211 - SANOC 7.8mb
xposed-v80.0-sdk23-arm64-custom-build-by-wanam-20160211 -WANAM 7.8MB
xposed-v80-sdk23-arm64-by-romracer-20160202
It would go from the Galaxy S6 Boot Menu startup to black screen and bootloop back to the original BootMenu or screen.
NO LED cycles nothing, but i can access Download Mode and Recovery But Updating Nor Uninstalling doesn't do anything to the rom, it just keeps boot looping unless i Flash the Stock back into place.
I'd like to have Xposed working i havent found a version for me that would work for this but i would really appreciate if everyone could help out.

Click to expand...
Click to collapse
Did it work. Ive only noticed a tad bit longer boot up the 1st time but all good.
i've tried most of them and i tried v80.0 or v80 and i got one part success half i didnt which was from it i got to the LTE spectrum screen and it just would go past that before it would just be the led flashing and bglank screen, i waited about and hour and still nothin changed from that screen.
Nevermind i made an update
This is what i've managed so far.... what am i missing here?
So here's what i"d take place in order to attempt a flash of Xposed Framework.
I start with Pre- Downloading the files for the MM 6.0.1 Stock Rom, it's in the forums Somewhere.
TWRP ( New_S6_Spr_TWRP_MM_Bootloader2 ) a.k.a 3.0.1
(This is a special version only for the Sprint SM-G920P and is meant to be flashed with Odin)
SuperSU 2.68 a.k.a ( BETA-SuperSU-v2.68-20160228150503 )
and obviously, Odin ( Odin3 v3.10 )
The steps that are taken place.
1st. I'd Boot my device into download/odin mode.
or
( while the device is powered off, i press and hold the home+power+volume down buttons.
and from there I'd be taken to a light blueish screen saying "Warning", and i follow through by pressing volume up)
2nd.
Once the device is in download/odin mode, and ready to go, i'd take my phone, plug it into my windows PC and open Odinv3 and from there
i'd select in odin, or i'd click the "AP" button and select the, tar file.
After that has been flashed thoroughly, I'd then proceed with the follow on screens, the 1st reboot and it updates or it says
Optimizing app 1 to 30.... the 2nd reboot where the hand free activation commences and
from that 3rd time it reboots and boots up again, i'd follow up with my login information.
3rd. once my device has been fully booted from the 2nd part, i'd then shut it down or restart it into "download mode again" and connect it to my pc again
and from there i'd load odin, and search or i'd find where I downloaded the special "TWRP .tar" or recovery file
and select the "Ap" option again and press start Afterwards.
After it flashes, right when its done i automatically hold the home+power+volume up buttons,
turn the device off and hold home+power+volume up and your should get some red text in the upper left hand corner with recovery not enforcing, that's okay dont be worried,
and from there it should boot into and be brought into TWRP...finally lol.
Now that's where you can flash SuperSU
4th. I'd leave my phone connected to my pc until, it's fully booting into twrp or i'd just connect it once im in the recovery.
I let my pc detect my phone and i'd copy both of these files.
SuperSU 2.68
and
Xposed
4th. After its copied, i'd go back into my phone, i tap install, and i select supersu and let it run, afterwards, i press reboot.
And let it sit for about another 2 minutes to do its own thing. Afterwards. once the phone is fully booted up.
I'd then go back into recovery, and flash Xposed and i'd wait about another 2-3 minutes for it to cycle
from the LTE Spectrum Screen to the, torquise colored screen where it's finally optimizing apps from 0 to 331.
5th. Once done, i'd finally have my advantage to install what i'd like which i'm doing as of right now still testing it out.
P.S if you do what i do for the SnapPrefs Module then i'd take in high note that before you flash the Xposed to download latest Snapchat 9.26
log in, once logged in then proceed with the rest and download XInstaller to downgrade from 9.26 to 9.17.1.0 to take full advantage of Snapprefs coolness.
upon note so far, after installing the modules, i rebooted my phone and it boots until it hits the LTE Spectrum screen and it has a light blueish pusling cycle and im stuck here.
maybe i can try another version. to be continued...
If you need any help feel free, i will try as best as i can, as i am a n00b but i have plenty of free time and have some decent knowledge about this.
After , i went back into recovery, i went to uninstall xposed thru the other flash file and its says optimizing 0 to 36 items and it booted so far, mayber after i flash the cache again and reinstall i should be fine but until further notice...tbc
Alright after a good amount of time i;ve finally concluded that the versions i;ve tired from xposed were the ones from the OFFICIAL thread and id always bootloop with that puling blue led and black screen, BUT with Wanams Xposed Version 80, and 79 they worked EXCEPT i can only get to the LTE SPecturm white boot screen and it does nothing from there BUT when i flash 80.1 it completely pulls through with the boot and completes but i had forgotten to mention that for some people on aanother thread that Xinstaller may leave you with bootloops and as it did for me thats exactly what happened. But i m still confused as to why the officials dont work by wanams does even after wiping cache,and dalvik cache multiple times and uninstall and reinstalling xposed.
Does yours still bootloop or did it finally pull through?

Rooted, TWRP installed. Custom ROMS won't boot

As the title says. As soon as I try to install a custom ROM phone doesn't even reach the LG Logo. Just boots to a log screen, with the last line mentioning fastboot mode (however its not in download mode).
Tried going back to stock and trying to reroot and installing twrp agiain, but no luck. Think there may be a problem with my phone.
Last time I had a custom ROM installed a couple of days, it kept crashing giving me a green screen log.
Any ideas?

Need Help. Phone stuck on black screen on boot

I flashed nusantara project 2.6(android 11) on my redmi note 5 pro along with nikgapps. Everything was working fine on booting but I didn't like the launcher. I saw that nikgapps had an addon package for pixel launcher and thought i'll install that. So i booted into my recovery and flashed that and rebooted into my system. On booting, I get the boot animation which gets completed and the phone boots but instead of the lockscreen, i only see a black screen. On holding the power button I see three options: power off, reboot and emergency call.
So i thought maybe the launcher was not compatible and that reflashing the rom would fix it. But I'm not able to boot into my recovery with any key combo. I'm also not able to boot into fastboot either. So I can't even use the miflash tool to flash a fastboot miui rom.
When booted into the black screen, miflash does detect my device when i connect it but when i flash a fastboot rom, nothing happens. It says flashing for an extremely long time and my phone is still in the black screen itself
Let me know if you have any ideas which i can try to fix this
Fixed it by going into edl mode and using miflash tool

Installing magisk creates bootloop

Hi,
I have an unlocked 6,1, that currently has lineage 18 ( official ) flashed.
I am trying to install magisk with no luck.
If I adb into bootloader, i can then ''fastboot flash boot twrp.img''
If i then reboot , I get twrp.
If I then flash Magisk zip ( latest ), and reboot, it doesn't boot back into lineage.
Sometimes I get a bootloop ( lineage animation ), and sometimes it just sticks on android one.
I have to keep pressing volume and power buttons until eventually, I get back to download mode.
From there, I can either try to factory reset, or worst still, reflash lineage.
Any ideas what I am doing wrong?
As an aside, in case it is relevant ,one thing I have noticed is, after powering off, when I plug power in, I dont get a battery charging sign - never have with lineage - instead I get a blank screen. I also can't get to stock recovery from the battery charging screen using VOL up/POWER.
Srangely, if I flash stock using OST ( offline), I get the battery charging screen ?
Many thanks in advance
