[LG V10 Q&A, Help & Troubleshooting] h960abrick:
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
