Bricked H960A after root attempt? - LG V10 Q&A, Help & Troubleshooting

Edit:
Problem solved - phone recovered, and rooted successfully. I think the problem was that I didn't use the most recent version of SuperSU. I was using version 2.46 iirc, but I finally got the root working with version 2.76 (filename UPDATE-SuperSU-v2.76-20160630161323). The TWRP version I used is twrp-3.0.2.0-0-h960a.img. (I used this version of twrp both in the failed root attempt as well as the successful one). After I attempted root with 2.46, the phone just hung at the "your device software can't be checked for corruption". To get my phone back, I booted it and connected to USB (you might have to enter fastboot by holding the down volume button and plugging in the USB cable, keeping the down volume pressed until the phone boots, or you might just boot the phone normally and plug it into the USB cable, even though the phone will "hang" doing this, lgup can detect it and you'll be able to "refurbish" with marshmallow kdz which you should have on your computer. I updated my phone to marshmallow before attempting the root, so I had the kdz already. The one I used is v20a. Anyway, after refurbishing, the phone is recovered and usable again, you still get the "can't check for corruption" screen on boot but it only stays for 5 seconds, and then the phone starts. This is normal for an unlocked bootloader. What I did after recovering the phone was to save SuperSU 2.76 (again, filename is UPDATE-SuperSU-v2.76-20160630161323) onto my phone's SD card. Then I reflashed twrp (boot into fastboot, then from console window "fastboot flash recovery twrp-3.0.2.0-0-h960a.img". Then I had to disconnect from the USB cable, and remove the battery. Apparently some phones will perform a factory reset if you attempt a reboot via the console after installing twrp - this is why I removed the battery - then I put the battery back in and booted into recovery mode. To do this (contrary to most instructions I found online which give the wrong button presses), I held the down volume arrow, and then pressed power until the LG logo showed up. Keeping the down volume pressed, I released only the power button, then tapped the power button until I got to a recovery screen (again, keeping the down volume pressed this whole time). Select "yes" both times and you should be in TWRP. Just follow instructions from there that you can find in rooting guides. When you're ready to restart the phone, you'll get the familiar "can't check for corruption" nag screen, but this will go away after a few seconds - LG logo will briefly appear, then disappear and back to that stupid nag screen. But after a few more seconds, the phone starts up. Confirmed rooted with rootchecker!
Below is my original thread where I describe the problem
So I unlocked bootloader, installed twrp and everything fine so far. I put supersu zip file into download folder, flashed with twrp, cleared cache, and went to system reboot - now the phone just hangs at "your device software can't be checked for corruption"
I should say that instead of pushing the supersu zip to sd card, I just saved it in 'downloads' folder of the phone. I also had to do the trick where I flash twrp, and then remove battery, restart phone to recovery mode, because a reboot of the phone would not allow me to use twrp (it just did factory reset)
I can get back into twrp via recovery boot via down volume + power, and I can get into fastboot via down volume + USB cable, but I can't get anywhere else.
I installed stock recovery image from here: droidviews. com/install-stock-recovery-on-lg-v10-using-fastboot/
Went into recovery boot, the android icon shows up and starts to work, but then goes right back to "your device software can't be checked for corruption"
How can I recover this phone? It's H960A
edit:
Ok, so lgup was not recognizing it, and I couldn't install kdz to recover android. I installed lgbridge, then plugged phone in via fastboot (down arrow + usb). lgup then recognized it, and I refurbished with mm kdz. Seems ok now, but still not rooted, and I still get the "your device software can't be checked for corruption" when I boot up (afaik this is because bootloader is unlocked). Tried to root again, same issue. Except this time lgup would not recognize from fastboot, so I just booted phone normally and connected via USB. Then lgup recognized it and I was able to refurbish again
How can I root this thing? at least I have a working phone again

rooting ls990zvg problems

just bought this phone off of craigslist.. I run the one click root methods and phone reboots but just continues to reboot into android. It's 5.0.1 and it's the ls990zvg .. do I need to restore to an older version to root?
Did you figure out how to root?
I recently rooted my stock sprint LG G3 running ZVG using this script: https://forum.xda-developers.com/sprint-lg-g3/development/ls990-zva-zvb-one-click-root-method-t3212433
However, when the script tries to reboot the phone into download mode, it just reboots into the stock ROM. What I did was just wait until the script times out, at which point I think it said something about you have to reboot into DL mode manually. So I just unplugged the USB cable, shut down the phone, held down the volume up button, and inserted the USB cable. It booted to DL mode, and then script found the phone and did its thing.
I tried using the TWRP app to flash the recovery, and it said it was successful, but actually it wasn't. I used Flashify to flash TWRP, and it worked fine.

Samsung Galaxy S6 cannot boot into OS even in safe mode. Need help to backup photos

My phone cannot boot into the OS. I would like to back up the photos directly in the recovery mode using USB cable+PC before factory reset.
Before the problem happened, my phone was attempted to update the software for about a week. Since it did not have enough free space, it prompted me to either free up more space or do the update later. I always hit update later. Until 3 days ago in the morning, my phone restarted (perhaps attempted to update) and stuck at the red Verizon screen and cannot power off unless power off from bootloader or Android recovery. I have tried to go to Safe mode but the phone just would not go past the red Verizon screen. If I go to Android Recovery by hitting power+volume up+home buttons together, it says system update (blue screen)-->update fail (blue screen with a dead robot)-->Android Recovery (black screen). In the Android Recovery, I have tried to wipe cache partition but still cannot get into the OS.
Now, I am hoping to back up the photos in my phone from a PC with a USB cable directly in the recovery mode. My phone is not rooted and does not have TWRP or any recovery app installed. When I connect the phone to a PC, the icon in notification (bottom right of Windows 10) shows that the PC can find my phone. However, when I go to "This PC", the phone does not show up in the "Devices and Drives." I have also tried Samsung Smart Switch and it cannot find the phone.
Please help! Thank you.

LG V300L unable to enter fastboot and recovery

I managed to get TWRP installed and flashed my V300L to H930 from the instructions in:
https://forum.xda-developers.com/lg-v30/how-to/korean-variant-bootloader-unlock-root-t3804505
TWRP was accessible via the reset menu.
However when I then decided to install the pixel experience rom into my phone I only had a black screen with prompts only showing by pressing the power or volume buttons so I flashed the V300L pie kdz back via LGUP.
After the flash, all seemed normal until I tried setting up google pay, it needed the bootloader locked or hidden by magisk so i tried to do both. Developer options say that the bootloader is still unlocked and I get the boot warning.
Problem is now my phone is unable to enter the fastboot menu and recovery. Trying to enter TWRP via the reset method just leads to resetting my phone, using "adb reboot recovery" reboots the phone to the dead android mascot and "no command".
Using the power down + plug in usb to enter fastboot just boots to a battery charging icon like you would see if your battery ran out and you plugged it into power. Using "adb reboot bootloader" just reboots the phone as per normal.
Download mode is working normally, I'm still able to use LGUP.
The phone works completely fine outside of these issues and not being able to use google pay (are my banking apps supposed to be working?). Is there anything I can do to bring back my fastboot menu / recovery?
v300 dont have fastboot mode . so to get twrp and fastboot mode, flash abl ,cmnlib, cmnlib64 files from h930 kdz through lg up and partition download option.
As mobile reboots after 80%, keep pressing volume down button, enter fastboot mode and flash twrp recovery ad magisk and other files.
BACKUP your data in PC before this, because you will have to format data after installing TWRP recovery

Magisk 21.2 bootloop

Hi everybody,
I tried to install Magisk 21.2 on my stock Oreo rom with Magisk 20.4 already installed. I've used the recommended method for installation in Magisk Manager, and I left the AVB/dm-verity option unchecked. It resulted in a bootloop.
Before updating I did a backup of the boot partition, so I could restore the previously working Magisk 20.4. Now I have two questions:
1) Is there something else I should do other than restoring the boot partition after a bootloop?
2) Is there a way to install the new Magisk or should I just dismiss the update notification?
Happened to me As well on my G6.
I had to reinstall the rom. good thing i had backup.
I've downloaded the zip file of Magisk 21.2 and flashed it with the rom after wiping almost everything, and even tried flashing a different rom with it (I'm using stock A9)., but it seems it resulted in a bootloop every time.
There is a new magisk 21.3 from yesterday, which i hope fixed those issues as i am not planning to go though that hassle again.
I tried the new 21.3, and still it causes bootloop, at least I'm glad I'm not the only one.

It happened to me, same setup as the OP and did the direct install method from Magisk Manager. My phone is stuck in bootloop at the triangle/! scrren and I can't access TWRP via the normal buttons manner. Also, can't get any ADB to detect the phone (I am using a new PC that probably never connected to this phone despite loading ADB, drivers, etc. - I am going to resurrect the previous PC to see if can connect).
May I ask how you restored the saved boot image? via TWRP restore?
I've rooted and played with many ROMs on various android devices, but I'm no expert and this one has me stumped.
Yes, I did a backup of the boot partition before flashing Magisk and then I restored using TWRP restore. It's not the first time that a new Magisk version causes bootloops on the G5, to I was prepared this time.
By the way, if you don't have a backup, you may try to flash the Magisk Uninstaller zip, and without rebooting, the old Magisk 20.4. In theory it should do the job.

Thanks, But how to access TWRP or flash the zip? I haven't found any technique to access recovery (Power+VolDn doesn't work, only allows Factory Reset screen). How to access Fastboot to use ADB (I assume that would be the technique)? I did manage to bring up some odd screen that had a two-line message about fastboot by, I believe, using Power+VolUp.
For clarification this is what I now have:
Phone off (remove battery). Insert battery. Press power button until brief vibrate (1-2 seconds). Release power button. Triangle with "!" displayed "Your device cannot be checked for corruption. Lock the bootloader. " screen displays for about 3 seconds, screen goes black a second or less. Back to the previous warning screen.
Press and hold Power button + Vol Dn acts just like the above, but if I press power + press/release/press/release... I can get the factory data reset (Yes or No(Exit) options) - I haven't accepted that.
I've tried connecting PC to the USB port and two things: as soon as I connect it, the phone powers on and does the looping again. My PC doesn't see the phone in Device Manager and ADB won't list it. I did (one time) manage to bring up the two-line fastboot message at the top of the screen.
BTW: when it first tries to power on, before the Lock the bootloader screen, there is a small, scrambled white area (text?) at the bottom of the screen.
I don't know when was the last time (if ever) I attached to the phone via USB (probably a few years ago when I initially installed TWRP). Haven't really done much other than upgrading TWRP (via TWRP), Magisk (via Magisk Manager), and the very occasional nandoid backup via TWRP (I have one from 3 months ago).
Any further assistance or info would be greatly appreciated.
To access TWRP, turn off the phone, then keep pressed Volume down+Power and once you see the LG logo release the power button and press it again. The phone should ask you if you want to reset everything: if you press yes and then confirm, you will:
1) Enter in TWRP, if you have TWRP installed, or
2) Erase the whole internal memory, if you don't have TWRP installed.
As you already have TWRP installed, it should be quite safe to go through the reset procedure, or at least that's what happens on my phone. If you don't want to take the risk, you can still use fastboot to boot a TWRP image you have on the pc, just write
Code:
fastboot boot <path_to_twrp.img_on_pc>/twrp.img
To do so, you first need to boot into fastboot: you can just turn off the phone and, keeping the Vol- pressed, connect the USB power cable to the phone. It will boot into fastboot.
One more method could be booting into download mode (Vol+ and connect the USB cable) and flashing an original firmware using LGUP, but that is way too much for a phone that already has both TWRP and fastboot accessible.

My phone never got past the bootloader screen (i.e. never got to the LG logo screen). When I booted into fastboot mode with the Vol+ button, I could issue commands like "fastboot devices" which would return that it saw my phone, but attempting to use fastboot to reload TWRP didn't work - some say the LG fastboot has been neutered.
Eventually, I had to indeed use LGUP/Uppercut and reload the stock Oreo and the phone came back up. BUT attempting to reboot into bootloader not only didn't come up in TWRP, but I got the little dead Android image. I ultimately had to downgrade to OEM nougat, jump through a few hoops, and finally got TWRP installed. Then it was just a matter of restoring a backup or reflashing a newer ROM (I ended up loading lineage 16, no gapps, with microg etc.).
Somehow the magisk upgrade really trashed my recovery partition somehow (??). I've always made sure to have at least a couple of TWRP backups, but this time I was screwed royally when I couldn't access recovery. I forgot what an ordeal it was to get TWRP & root on this phone originally.
Thanks for your help.

Switched ROMS (Evolution X -> Nusantara) -> NOW Bootloop

Hi Community,
I read some posts how to fix my Problem, but i cant go to a service Point.
So I was using the Evolution X for a long Time (Installed with TWRP 3.1.0).
And now i wanted to change to the Nusantara Project (Vanilla), I did a clean Flash, everything worked i could access the System.
Than i had problems installing Play Store, so i rebooted into Recovery via the System. But now im Stuck in the Loop.
Can i Somehow connect my Phone to the PC and Reset?
Can someone tell me if i Hard/soft bricked my phone ?
Just a little advice, would be really appreciated.
Thanks a lot
Go to TWRP, wipe system, cache, data and dalvik. Now flash nusantra and whichever GApps are recommended for it (if there are no recommendations then use OpenGApps, make sure the architecture is correct). Now wipe dalvik and restart. Sometimes, certain roms begin to bootloop if you boot into the rom first, then try to install gapps later.
If you still have issues, just reflash the stock rom.
I cant access the TWRP anymore, im just stuck on the Bootloader, no matter how i turn on The Phone (Volume Up + Power ON ), (Volume Down + Power), (All 3 Buttons)
Nothing works anymore i dont understand ....
Im searching the net but i cant go to fastboot or something else, its just keeps on rebooting ...
So it's bootlooping, but you cant access recovery?
When the screen turns off, press the key combo and it should go to recovery.
Your best bet is to take it to a service centre, but if that really isn't possible for you, then wait for its battery to drain completely, then when you plug in the charger, instead of turning the phone on, press the key combo to enter the recovery. From there, wipe and flash some other OS.
I've also heard that certain versions of TWRP don't support some roms, leading to a bootloop. In that case, you'll have to use orangefox recovery to flash the rom (orangefox is flashable via twrp)
Yes its Bootlooping.
When i turn it on, on the Left Corner "Recovery Mode" blinks for one second. Than the usual Text appears:
"Orange State
Your Device has been unlocked and cant be trusted
Your Device will boot in 5 Seconds".
So after a couple of seconds (around 10-20 sec)
It turns off and immediately on again. I Just can turn it OFF when i hold all 3 Buttons.
Than i try starting it with Volume up + Power / Volume down + Power, But i cant access Recovery or TWRP.
So i should wait til the battery gets low and try it again ?
Like i said, my custom Rom (Evolutionx) and TWRP just worked fine. I dont know man ...
Well since your bootloader is unlocked, try flashing the stock rom again. Look for a tutorial and follow it.
Hi I managed to unbrick my device with this guide, and im back on a stock rom
Unbrick
i ran following commands to get to my custom rom:
I run adb reboot bootloader,
add executed following commands.
(Pitch Black recovery 3.1)
- adb reboot bootloader
- fastboot flash recovery recovery.img
-fasboot reboot recovery
It just hang up and booted after a while into the normal system.
But im not able to get to the recovery menu ?
When I restart and hold Volume up + Power, i go in a loop and the phone keeps restarting over and over again.
what have i Fu**ed up ?
Do i need another recovery tool ?
sorry guys, i appreciate your help a lot tho !
EDIT: Is my bootloader unlocked ?
I can access via "adb reboot bootloader" the phone
and on the blackscreen on the phone it is written:
oppo verfiy pass
fastboot_unlock_verify ok
Update:
So i tried some Stuff and i got Red State. No Problem i Unbricked it once again and now im on Stock Android 10.
Now im Trying to enable the bootloader again.
I downloaded the In Depth Test_Realme_6.apk but i keep getting the Error that i should update the system.
So should i update the system ?
I cant find a CURRENT Tutorial to make this work, please help...
If you cant find a tutorial for your version, why not downgrade back to a previous one if possible.
