I looked through the post and couldnt find it.

Im getting pretty frustrated with this. Ive never had this much trouble rooting a phone before. Im afraid ive bricked this phone and wasted all the money on it.

If someone can walk me through what to do from the stuck verizon screen, I would appreciate it. At this point, im willing to go back to factory.

[LG V20 Guides, News, & Discussion] emdroidle:
Where were they doing this? I know of an open source program written in Python which can communicate with Download mode. They ran into a problem that the modern versions of Download mode appear to use a cryptographic challenge-response before allowing the interesting commands.

Rooting the V10 was done by modifying LGUP_common.dll to complete the challenge-response without verifying the KDZ/TOT file. Then simply using an appropriately modified TOT file.

You shouldn't need it, lglaf can execute arbitrary commands in Download mode on a G4 without any authentication because on the G4 Download mode didn't have any authentication. I'm unsure what modifications are needed to root a G4 though. May involve a fair bit of reading.

You should read what is in that error message. PowerShell is telling you exactly what you need to do. Notice the "suggestion"?
[LG V20 Guides, News, & Discussion] nwalker77:
Obviously I'm overlooking something. What do you see that I don't?
[LG V20 Guides, News, & Discussion] emdroidle:
Notice the text "Suggestion [3.General]:"?

So put "./" around the whole command?

ALL VERIZON VS995 USERS HAVING ISSUES. READ THIS FOR FIXES.

First make sure you are on VS99514A OR EARLIER (Instructions to downgrade here: https://xdaforums.com/v20/how-to/restore-v20-to-100-stock-bricked-devices-t3524903)

Or else you will have issues with the terminal entries and applying patch.

Second, REPLACE the twrp-3.0.2-1-us996.img with twrp-3.1.1-0-elsa.img in your adb folder (download here: https://xdaforums.com/devdb/project/?id=20590#downloads)

but RENAME the new twrp-3.1.1-0-elsa.img to twrp-3.0.2-1-us996.img (make sure you don't confuse yourself) so that the batch files still work

Third, if getting STATIC screen or taking forever to boot after step 3, instead of fastbooting bootbackup.img (as posted in the instructions), fastboot boot2.img instead. (Pull battery, unplug cable. Put battery back, hold volume down, plug cable back in. In ADB cmd, type "fastboot flash boot boot2.img"). Once you reboot, you will now see the corrupt screen with the red triangle.

Fourth, after all that, if it boots up to a secure password screen (and unable to reboot recovery using adb), pull battery and plug. Press and hold volume down and power. Lift power button when vibrate and press again when LG logo appears. Select yes to factory reset, and yes to confirm. If twrp was installed properly, you will boot into TWRP.

Follow the rest of the instructions as you normally would and flash your ROMs/Kernels.

In powershell, this is what I get.

Nothing happens on the computer or phone.

Stuck on Static screen

Running Sprint LS997 and Windows.

I thought I was set-up with ADB, but am new to this, so maybe I wasn't. When I clicked through RUNMEFIRST, but I don't think it asked me to run Step2, but I proceeded anyway. :(

I have gone through all the steps in TWRP but when I boot I get a screen of static. I have gone back through steps 3 and 4 of the TWRP section a few times, but still have a screen of static (and the ladies voice explaining accessibility features).

So is there anything I can do at this point? or is this what you call a brick? I can consistently enter TWRP.

I didn't really understand what it meant to have ADB and Fastboot set-up. Now I am understanding that the RUNMEFIRST, and Step2, probably utilized these commands. Is that correct?

I appreciate any help.
[LG V20 Guides, News, & Discussion] Holyman007:
If you can hear a narrator explaining accessibility features, that means you've booted properly. Try turning off the screen and covering the proximity sensor for 5 seconds (until no static on the second screen). This should fix the static until next reboot.

If you can enter TWRP, then try flashing a rom that has the static fixed (like WETA).
[LG V20 Guides, News, & Discussion] Sands207:
try .\fastboot instead.
[LG V20 Guides, News, & Discussion] nwalker77:
That worked. I cant tell you how much I appreciate the help.

But now its stuck on the static screen. Any ideas?
[LG V20 Guides, News, & Discussion] Sands207:
I don't own your device so i can't help you there but hopefully someone here can. i wish you the best of luck, hopefully you can get situated ✌️
[LG V20 Guides, News, & Discussion] nwalker77:
Ah, thanks anyway.

I did get the static screen fixed. But it says I don't have root!
[LG V20 Guides, News, & Discussion] SmashFace:
Thank you so much. Weta, doesn't look good for Sprint so I went with DEVDIGITEL's. I couldn't be more satisfied. I thought I was in a pretty dark place.

Looking for some guidance here. I have completed the RunMeFirst, FirstStep, and SecondStep. I cant seem to get my phone into Fastboot. Im on Verizon VS995 with VS99513A.

Running step 3 results in a waiting for device. ADB works without issues. Phone is listed as a LGE Mobile for VZW USB Serial Port (Com3) in Device Manager. Phone has USB debugging enabled. Im using File Transfer for the USB connection type.

Typing adb reboot bootloader or adb reboot recovery results in the phone booting normally.

How do I get into fastboot mode and how do I ensure it is working so I can proceed with step 3?
[LG V20 Guides, News, & Discussion] raven213:
got it thanks :)
[LG V20 Guides, News, & Discussion] whitedragon551:
Ive gotten past step 3. Im to step 7. If I do step 7 I cant get into TWRP as the screen is static. So I followed another post on this thread that says instead of the command in step 7 use Fastboot flash boot2.img

Im trying to get to step 8 now. If I use the above method. Step results in a Your Device is Corrupt error. If I follow step 7, I cant see due to static to get to step 8. Any ideas?
[LG V20 Guides, News, & Discussion] rholm:
Read post 2. The ReStock kernel, WETA ROM, and others will fix the static screen.

[LG V20 Guides, News, & Discussion] whitedragon551:
I did and it didnt. Its ok. None of the ROM"s were that great any way. Definitely not worth the hassle of rooting, TWRP, and flashing. I went back to stock.
[LG V20 Guides, News, & Discussion] variance:
just to confirm.. and this may be stupid. but there is no root method without flashing this developer/debugger bootloader, correct?
[LG V20 Guides, News, & Discussion] me2151:
correct.
[LG V20 Guides, News, & Discussion] cityneversleepz:
If you take your time with the process and follow the steps carefully, you will get root and will be able to flash custom ROMs without any noticable difference to your phone. The only thing you'd see now that all the bugs are gone is a boot screen that tells you your device will not boot. Of course it boots right after you see that message. So nothing to worry about.
[LG V20 Guides, News, & Discussion] cyris69:

Your device isn't listed in the OP. you might brick if you try to root. Maybe someone that knows more than me will confirm.

I'm going to attempt unlocking via LG's site. This really is a hassle to unlock a bootloader on a device. Their website is awful.
[LG V20 Guides, News, & Discussion] Knowbody42:
Using an unlock.bin from LG is definitely the better way to unlock the bootloader (fewer potential problems). It's just that LG doesn't allow all variants unlock that way.
[LG V20 Guides, News, & Discussion] Ilxaot:
I unlocked it. I does this mean I can flash TWRP without repercussions?
[LG V20 Guides, News, & Discussion] Knowbody42:
Yes, TWRP will work if you've unlocked the bootloader.

Search the thread. I'm pretty sure you can get rid of the static with a custom kernel. I'm on sprint and the classic ROM doesn't have static.
[LG V20 Guides, News, & Discussion] me2151:
Yes it works. problem is when you do the bootbackup you need to boot directly to twrp after or you will lose twrp. Just reinstall twrp and boot directly to it. then install a root package.

I'm not sure if anyone can help with this. I'm on a VS995 and i have successfully rooted on 13A. The problem is that my camera app doesn't work properly. When i touch the screen to auto focus, the camera doesn't do anything. Also, when using the BofA app, when i try to deposit checks, it won't open the camera app properly. It's just a black screen. I've verified that this only happens after root. I used Uppercut and LGUP to return to stock and checked that the camera is fully functional. When i touch the screen, it will try to focus on wherever i tapped. It also worked correctly in the BofA app. What can i do to fix this? Any ideas? I used the search bar to see if anyone else had this issue and couldn't find anything.

Help

At step 3 I run the bat. file and it run through the process several times always getting the error: "Cannot load twrp-3.0.2-1-us996"

I cannot, for the life of me, find out what I'm doing wrong. Does it matter where I put the file on my device?

Edit: Turns out I'm retarded. I COMPLETELY skipped the fact that I was supposed to mash all the files into the same directory on my PC.

*facepalm*
[LG V20 Guides, News, & Discussion] LittleCloud.rar:

I went back to step 3; flashed both SuperSU and the konverged kernel and it now boots up fully. But, it doesn't seem to have done anything as SuperSU isn't installed on the device and it doesn't boot into TWRP through the "adb reboot recovery" command.
[LG V20 Guides, News, & Discussion] me2151:
gotta flash su AFTER the kernel
[LG V20 Guides, News, & Discussion] LittleCloud.rar:
Okay so here's what I've done.

1.) I used uppercut to revert back to "VS99512A_06_1114_ARB00.kdz"

2.) I then followed the steps up to the Flashing TWRP portion (Although I'm not sure if I was supposed to do step 3.5 in the first section "run-as con

chmod 0777 /storage/emulated/0/*",[I have a Verizon phone and I'm doing this on Windows])

3.) I then ran Step3 and proceeded to TWRP where I flashed the "konverged-0.3-v20-h918-7.0", wiped the dalvik and cache, and rebooted. (I also noticed "unable to mount storage" in red text)

4.) I returned to TWRP and flashed "SR5-SuperSU-v2.78-SR5-20161130091551" and followed these steps:

5.) I proceeded to let my phone sit with a static covered screen where it idled for ~35 minutes before I attempted this fix:

where I was presented with "error: cannot load 'bootbackup.img'." This is where I'm certain **** hit the fan as I tried: "fastboot flash boot C:\adb\bootbackup.img" and rebooted afterwards where I landed at the setup screen on my phone and was able to complete the setup.

6.) I then attempted step 7 and entered "adb reboot recovery," which led the phone to reboot back to the lockscreen rather than enter TWRP and that is where I am currently; in LIMBO.

Help! I got as far as booting into TWRP for the first time and did the format. It wasn't clear to me where I could flash SuperSU.zip. Even though I had previously downloaded it, I couldn't find it. I presume it got wiped out when I formatted.

So now i am at a point where the phone is at - fastboot: processing commands and buzzing like a firefly. What happens now, as I'm stuck here.
[LG V20 Guides, News, & Discussion] AnUnseenHope:
Did you save SuperSU to the SD card or the the root of your phone? If it was to the root of your phone, it most likely got wiped. Save SuperSU to the SD card and select SD Card when you go to install the zip.

If you're stuck in fastboot, run step 3 again and follow the directions from there forward.
[LG V20 Guides, News, & Discussion] brucejg:
I'm further down the rabbit hole now... It boots into a "static" screen and I can go no further. While I was previously able to boot into TWRP, I can no longer do so - this includes pressing down volume, power, and then hitting power when I see the LG screen and then wiping.
[LG V20 Guides, News, & Discussion] AnUnseenHope:
Which V20 do you have? Can you see it in adb when plugged into a computer? Static is normal. If anything, you can download/install LGUP and Uppercut to return to stock and start over. You will need to get the proper kdz file for your model as well.
[LG V20 Guides, News, & Discussion] brucejg:
It is Verizon 995. ADB doesn't work in this condition because USB debug isn't toggled. How will I be able to download anything if ADB doesn't connect and TWRP doesn't come up?
[LG V20 Guides, News, & Discussion] AnUnseenHope:
You don't need adb to return to stock with uppercut and lgup. All you need to do is pull the battery, put the USB into the computer (but not into the phone), replace battery into the phone, and while hold Vol Up, plug the other end of the USB into the phone. It will boot into download mode and you can reflash your phone to stock.

---------- Post added at 05:01 PM ---------- Previous post was at 04:57 PM ----------

Also, there's a post in this thread about Verizon phones and the static/not booting problem. When stuck in fastboot to "fastboot flash boot boot2.img'

Search bar is your friend
[LG V20 Guides, News, & Discussion] brucejg:
I saw that earlier and understand but ADB cannot connect to the phone so fastboot won't either. What else can I do?
[LG V20 Guides, News, & Discussion] AnUnseenHope:
Get Uppercut, LGUP and the version 12 or version 13 kdz for the VS995. Flash to stock and start over. Just get your phone into download mode with the way I explained earlier.
[LG V20 Guides, News, & Discussion] Manticore116:
Shouldn't that be mentioned in the guide right at the start? Kinda feels like false advertising to say that this works on the H910, but only if you haven't updated your phone in 8 months... I mean they are sold new with this patched at this point, so if someone were to look to see if they could root it before they got it and then found this thread and read the guide then they might go out and buy it, only to find out later that that's just plain wrong...
