adb runs on your computer.

You'll have to get adb on the laptop first. Then you'll have a folder with an adb.exe in it. Once you have that folder you can hold shift and right click in the folder and a context menu will come up, choose "open command window here". Then you'll see a command prompt that will say adb> with a flashing cursor. I have my adb folder directly on my C:\ drive so it shows as C:\adb> (I like to keep directories simple because sometimes you have to type out directory names to move files and if you have it buried deep in a folder somewhere that just means more typing. If you put things directly on your C: drive then you only have to type "C:" :D Anyway...sidenote.) So once you have the command window open and it's showing adb> type "adb devices" if your phone is showing as connected it will tell you by showing the device model number/name. If no numbers or names appear then it's not reading it. You have to resolve that before doing any other steps. Make sure USB debugging is enabled on the phone, and try changing your USB connection to charging mode or from charging mode to file transfer if it's not reading. For some reason I was required to have my USB mode set to charging before adb would see my phone.

here is a tutorial for how to install adb I haven't personally used that method but it's from a trusted source and the most recent I could find. Also, there are probably some good YouTube videos on how to get adb on your computer.

EDIT: the guy above me proved my point about the typing out long directories :D Who would want to type all that when if you put adb directly on your C drive all you have to type is C:\ :p

The card could have been read from TWRP or you could have just copied it using an SD card reader to your pc, formatted then copy it back.

I did the latter as it is a few hundred percent quicker.
[LG V20 Guides, News, & Discussion] imucarmen:
I don't know. But I will warn you you're going to be scolded for asking that here :p basically you're in the wrong thread :) I'm currently using the US996 rom and the same kernel as you. I'm finding the battery life sucks and the phone runs warmer with it. I hope some official verizon roms come out soon.
[LG V20 Guides, News, & Discussion] esqueue:
Scolded? Why? They will most likely say that they don't know as it hasn't been tested out yet. That or give a reason why It wouldn't work. The Konverged fixed many issues but it seems that the posted kernel can possibly fix FM. I will not bother as my phone is working great at the moment.

The Konverged version fixed my BT, slow boot, lag, stability (wouldn't call some numbers and would randomly freeze), and battery drain issues. Things like Wi-Fi calling, and FM are things that can wait as I almost never use them.
[LG V20 Guides, News, & Discussion] LuckyColdJohnson:
Thanks for taking the time to write this up. USB mode for me had to be set to File Transfer Mode (MTP)
[LG V20 Guides, News, & Discussion] imucarmen:
You'd think that would be for everyone but for some reason adb wouldn't read my phone until I switched it to charging mode. I found that a bit strange tbh.

And you're welcome.
[LG V20 Guides, News, & Discussion] Nevea:

Hey guys, could definitely use some help here. Everything went just fine until after Step 3. Hung for ages on the Verizon Boot Screen (over 20 minutes) and I (perhaps stupidly) tried to do the battery pull trick and fastboot as in original post but now can't get to TWRP (haven't seen it at all yet though I *think* the install of it worked). All I seem to be able to do now is get to fastboot screen (no adb, it seems) or regular boot which takes me to the secure start screen (which is now at 5 attempts left). Got me ****-scared I may have messed up my brand new device. Unless I'm just making a rookie mistake. Any help would be much appreciated!

Thanks!

---------- Post added at 05:08 AM ---------- Previous post was at 05:03 AM ----------

Took a chance and restarted from Step 3. Sitting on Verizon Boot Screen loading again. Do I just sit here and wait patiently? Shouldn't TWRP have kicked in before the Verizon screen ever came up?

---------- Post added at 05:40 AM ---------- Previous post was at 05:08 AM ----------

And still nothing after a half hour. Went back to fastboot to try:

fastboot boot boot1.img

fastboot flash recovery twrp-3.0.2.1-us996.img

fastboot reboot

Once again at Verizon loading screen. Again, shouldn't TWRP have kicked in before ever getting to Verizon loading screen?

Do I just leave it running all night? LOL. (that's actually a sad LOL - could really use some help!)
[LG V20 Guides, News, & Discussion] imucarmen:
I have a weird one. So i restored a backup, decided to do a factory reset inside the rom (even though I told myself I should use TWRP instead) and now I can get anything to boot. I can get to TWRP, I can use adb, I can adb sideload, I can restore both my backups, I can flash the a rom, but nothing will boot. It goes from the corrupt phone message, to the LG logo for about 5 seconds and then back into recovery. I'm not a complete noob with this stuff so I've been trying everything I know how. Since I can't get back into the phone I've run the dirtysanta method again from step 4 but the same result. I even went into fastboot and ran "fastboot flash boot boot2.img" but still just boots to recovery. I'm pretty much out of ideas. Never had a phone brick while still being able to use recovery and adb so I'm thinking there must be a solution to this.

---------- Post added at 12:43 AM ---------- Previous post was at 12:41 AM ----------

Did you run the "fastboot flash boot boot2.img" in fastboot?
[LG V20 Guides, News, & Discussion] kberk001:
Did you run the "fastboot flash boot boot2.img" in fastboot?[/QUOTE]

Previously yes, didn't seem to do anything, although I'm not sure what the difference is between the 2 boot images. Was trying to follow what the solutions were for people kinda-sorta similar to what I had but nothing has worked so far. No way to get into TWRP. Are you suggesting flash boot1.img, then boot2, then twrp, then reboot? Really out of my depth here!

Thanks for trying to help. Any more clarification would be appreciated!

[LG V20 Guides, News, & Discussion] nahepler90:
My device was doing the same thing. Had to have someone help me out with mine. When it is at the verizon loading screen, check and see if it is being detected as an adb device. Ended up having to do adb > adb reboot recovery from that screen. Then follow directions from that step. Hope it works!
[LG V20 Guides, News, & Discussion] kberk001:
Sadly, no. adb devices shows nothing under List of devices attached.

Any other ideas to get past that?
[LG V20 Guides, News, & Discussion] nahepler90:
Did you flash boot1.img or boot2 last?
[LG V20 Guides, News, & Discussion] dwertz:
What boot image are you on?
[LG V20 Guides, News, & Discussion] kberk001:
Last was boot1.img, because I'd done these:

fastboot boot boot1.img

fastboot flash recovery twrp-3.0.2.1-us996.img

fastboot reboot

What's next if I can't adb but can fastboot?
[LG V20 Guides, News, & Discussion] nahepler90:
Just a question, but did you type "flash" after fastboot for the boot1.img? Little mistakes like that can be easily overlooked. Are you getting any device showing up in your device manager when it is plugged in and on the verizon loading screen? Could say "Android /!\" or another device you dont recognize with a yellow triangle with ! In it. There were a couple times I had to right click and update the drivers because my device was showing up like that.
[LG V20 Guides, News, & Discussion] dwertz:
boot2.img should be the last boot image before flashing the AT&T H918 Converged Kernel

so

fastboot flash boot boot2.img
[LG V20 Guides, News, & Discussion] kberk001:
Nope, didn't fatfinger it, to the best of my knowledge. Nothing out of the ordinary in device manager. Just don't know how to force adb to kick in, if that's even possible.

At this point, I can only do fastboot, where it does show up in devices, or try again to boot "normally" in which case I think I get to the Secure Lock screen with only 5 chances left.

Any other ideas? Thanks all, for trying to help me out of this mess!

---------- Post added at 06:23 AM ---------- Previous post was at 06:21 AM ----------

but should I be doing that even if I can't get to TWRP, or is that a step AFTER where I'm stuck? Did boot2.img and it didn't seem to help, nor push me into TWRP, but I'm not even sure if it's supposed to or if the flashing of TWRP is done separately as part of Step3.bat, where mine says:

fastboot flash boot boot1.img

fastboot flash recovery twrp-3.0.2-1-us996.img

fastboot flash boot boot1.img

fastboot flash recovery twrp-3.0.2-1-us996.img

fastboot flash boot boot1.img

fastboot flash recovery twrp-3.0.2-1-us996.img

fastboot flash boot boot1.img

fastboot flash recovery twrp-3.0.2-1-us996.img

fastboot flash boot boot1.img

fastboot reboot

Sure there's a reason for all the duplication but this entire thing is way above my paygrade!
[LG V20 Guides, News, & Discussion] dwertz:
boot2.img would be after that step of flashing twrp.

when you are booting does it go into the LG screen? you can keep typing "adb reboot recovery" and keep doing up arrow so you don't need to keep typing. maybe it will boot to the point that you can bring it into recovery?

I believe the repeats are to make sure the flash takes.
[LG V20 Guides, News, & Discussion] kberk001:
It goes into LG screen for a few seconds, then into verizon one. Will try again but adb reboot recovery doesn't seem to do anything unless I'm missing my timing.

If you're saying boot2.img is after the step of flashing twrp, I'm assuming I'm not "there" yet if I can't even get into TWRP, right?
[LG V20 Guides, News, & Discussion] mamenvn:
boot image is in v20-root.zip (boot1.img, boot2.img)
[LG V20 Guides, News, & Discussion] kberk001:
Holy ****ing ****. In TWRP! Lemme see if I can get through this without ****ing up and I'll post what transpired. It was barely different but *something* worked!
[LG V20 Guides, News, & Discussion] dwertz:
I am thinking you already flashed TWRP but can't get to it from the boot loader. Did you try to flash boot2.img? It should then boot. If it does boot, it will say sdcard is corrupt, ignore that. Its not corrupt, just boot2.img can not see ExFat. Do not format it.

So try

Fastboot flash boot boot2.img
[LG V20 Guides, News, & Discussion] mamenvn:
boot image is in v20-root.zip

TWRP Recovery runs fine, although whenever I now boot up my phone it goes straight to TWRP recovery.
[LG V20 Guides, News, & Discussion] imucarmen:
if anyone knows the solution to being stuck in recovery after doing a factory reset from inside the ROM (not TWRP factory reset but in the ROM settings) please let me know. I've noticed this has happened to quite a few people but I've failed to find a solution. I've exhausted my knowledge on this. I've tried running backup restores, I've clean flashed roms, I've rerun the unlock/root method several times, I've been in fastboot flashing the boot 1 and 2 images, I've formatted, wiped, rebooted and everything else I can think of. No matter what I've done I end up back in recovery. it gets to the LG logo, then the screen does the static thing, and then it goes into recovery.

I have fastboot, TWRP, and can use adb. This tells me there must be a solution. I'm just failing to find it.
[LG V20 Guides, News, & Discussion] dwertz:
boot into bootloader

fastboot flash boot boot2.img

this should allow you to boot. The sdcard will say corrupt, ignore for now.

---------- Post added at 11:50 PM ---------- Previous post was at 11:47 PM ----------

Do you have a backup of the system? Mine had this issue but I had system backed up. In TWRP I used file explorer and the /system was empty, but when I mounted it there were files. I ended up doing the following and it was able to let my /system mount during boot.

Power Off

Weird. It's booting now. So I did what you said but it still booted back to TWRP.

[LG V20 Guides, News, & Discussion] saboture:
For those who have the AT&T H910 and have used this method to unlock your phone and install twrp, I was able to flash the stock deodexed rom for the US Cellular 996 V20 without issue. I made a twrp backup and then wiped caches, data and dalvik, then flashed the rom, then the konverged kernel on top. I still get the static screen on boot but i feel like the rom is hella smoother. Theres no wifi calling, and i dont use the fm radio so i uninstalled it. Be forewarned though, before i flasbed the rom i had tried to do a twrp restore of the rooted oem rom and i got a kernel crash error. After wiping i decided to flasb the 996 rom.

Edit: after flashing the rom, first boot takes a good 10 minutes so go make a sandwich
