rooting ls990zvg problems - Sprint LG G3

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.

[Q] Flash clean constantly restarting rooted LG Optimus L5 (E612f)

I have an LG Optimus L5 (E612). I successfully rooted it, some three weeks ago, by following these instructions. However, as of December 25, mobile device has been acting up; the problem seems to have started when I attempted to update SuperSU. The problems:
I cannot install or uninstall apps and it constantly reboots on its own.
When mobile device reboots, it appears to go to state it was in on December 25... apps uninstalled via adb for instance reappear after device reboots
What I would like to do is completely wipe it clean, using a factory reset or some sort thing. But I am unable to do that that... This is what happens:
a normal factory reset via settings fails
a factory reset by holding volume down, power button and finally home key fails as devices restarts after about 5 seconds
attempting to using fastboot erase [cache|userdata|system] fails as device restarts as soon as I issue command
I have been attempting to flash mobile device using fastboot, but I have had little luck there as well. How do I go about resolving this issue?

Your phone doesnt have fastboot. Backup your data and flash a KDZ.

I am a newbie at all this, could you please help with links to posts and/or resources that will help me 'flash a KDZ'?
I tried flashing, but I still have not had any luck with this.
KDZ Updater: I have attempted flashing... flashing process appears successful but problem still persists;
LG Software Updater Tool: This was probably the last straw. I hooked up phone via usb, in debugging + PC Suite mode... this was a success but problem is still there
Interestingly enough, the problem goes away after booting in Safe Mode; I can uninstall apps and even gain root access via adb. However, problem resurfaces after rebooting---apps I uninstalled are restored. Any idea what I could do here?
All I want to do is clean up device so I can start on a clean slate here...

Bricked H960A after root attempt?

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

Galaxy J5 bricked and home button broken

I ran into a serious problem and now I do not know how to fix it. It turns out that I wanted to install a rom to my cell phone, since the stock I had was giving problems with the battery indicator, and I tried to calibrate it and even used others also following different steps to calibrate them, but always the same problem; Well, after root I found the problem that I could not install anything from the recovery mode of the cell phone, there was a problem that was disabled and could not from the sd, or internal, or adb or anything. Finally I decided to find an application to install twrp and flash the rom, downloaded flashify and I did.
When I went into recovery to flash the rom the cell phone did not change the logo with the message in a corner that is not the official recovery as always comes out when a custom is installed. And there it stays.
I can not turn it on normally, because each time I turn it on it goes directly to the logo with the message that it is not the original recovery, as if trying to access the recovery.
PS: I can not use odin, it does not recognize the cell phone when it is in odin mode, since all the drivers are installed and the kies, I reinstalled everything 3 times every time I tried it. And I can not enter odin mode, and the home button does not work, I used adb, but since it does not turn on, it does not recognize it either.

To enter in to the download mode you can use JIG USB which looks like this :

You can buy that jig USB on E-Bay
or you can use this tool but little Warning !!!

File was scanned against viruses and it has some , maybe because like that he make your device in download mode.

Here is video how to use .

Good Luck
I'll try with the usb jig. Still don't know if buy the resistance and make one or just buy the jig. Then i will see if i can get for odin to detect the phone, using some kind of witchcraft or whatever hahahaha.
Thanks, I will set the thread as solved.
Good Luck

Dirty Flash wiped TWRP from LG-H932. Unable to get TWRP back on.

Hello One and All,
Apologizes if this is in the wrong section. As the post stated, i did a dirty flash of a rom on-top of itself (https://forum.xda-developers.com/lg-v30/development/stock-t-mobile-lg-v30-stock-collection-t3980701) to force the kernel to change. This, somehow, removed TWRP from the recovery (even tho the rom said that it wouldn't touch the recovery) so now when i do the button dance, it master resets the phone instead of going into TWRP. Phone still has the bootloader unlocked, but download mode will load, sit for a moment, then restart. 3 computers, running Win10, and FWUL bootable USB doesn't recognize the download mode, also tried different USB cables.
Attempted to use LGUP to essentially follow the rooting process from start to finish, but once the LGUP attempts to load the 10D.kdz onto the phone, the phone just reboots and LGUP does nothing but complain about connectivity to the phone.
Anyone have any suggestions or am I SOL? At least my phone still functions, it's just in the odd middle ground of not having root, but some applications wont work because it thinks it's rooted (Google Pay NFC).

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.
