I'm on lineage rn and I think it's great. Way faster and smoother animations than the LG UI. If only there was a way for the second screen to work.
[LG V20 Guides, News, & Discussion] Lumince:
So this is bugging me alot!! I keep getting what looks like screen burn ins... It cant be because this is a LCD screen.. So it has to be image retention... This phone is so amazing. And root makes it so much better... But this image retention is just annoying...
[LG V20 Guides, News, & Discussion] MPH33:
Huge Massive Fail!!! i did this procedure to the exact directions and failed miserably. copy paste twrp to fastboot, then went to step 3. would not upload twrp. removed battery to go into twrp( factory reset white screen have to click yes twice) then screen freezes for several minutes then screen goes static for 30 seconds, reboots and then stuck in lg logo. ive tried everything. not certain what went wrong. follow directions precisely. Sprint LG V20. i noticed in a youtube video that it said you have to upload stock rom. never did i see that on the 1st page of this thread. i think this will be a permanent stuck logo bricking. 1st time i ever bricked a phone :(

Sorry to hear that. In the first post, the directions for sprint instructions. Step 4.3 says to install stock sprint ROM.

no turning back? no way i can upload stock rom? is this a permanent brick?

So when you did the fastboot install recovery twrp.img what did it output if you say that it failed?

As long as you have fastboot access you typically should be okay honestly.
[LG V20 Guides, News, & Discussion] david279:
Install TWRP and boot to it. Download stock ROM to a micro SD if you have one and install it.
[LG V20 Guides, News, & Discussion] MPH33:
i have full access to fastboot. twrp is failing in step 3. is the twrp link corupt? im copying twrp from pc and right click pasting to fastboot from adb. its not allowing twrp in step 3
[LG V20 Guides, News, & Discussion] david279:
Try downloading it again
[LG V20 Guides, News, & Discussion] MPH33:
ive deleted and downloaded the twrp image file several times. fastboot refuses to upload twrp. i think the file is corrupt. is this the only twrp us 996 file? not certain why i can do every process from this root buy twrp wont work

And your doing

Fastboot flash recovery twrp.filename?

---------- Post added at 12:41 PM ---------- Previous post was at 12:28 PM ----------

Something maybe wrong with the TWRP file. I can't even download it from the link in the first post.
[LG V20 Guides, News, & Discussion] MPH33:
yes. im copying downloaded twrp image and pasting in fastboot. then proceeding with step 3. during the speedy process it will say can not upload twrp

---------- Post added at 09:21 PM ---------- Previous post was at 08:47 PM ----------

i cant believe this process was soo easy but twrp image file wont work on fastboot. the file must be corrupt. ive tried downloading the twrp file from 2 different locations. every time i go through step 3 it refuses to upload twrp. this will be lame as hell if i brick my phone over such a simple process
[LG V20 Guides, News, & Discussion] MPH33:
IM SOOO FVCKING MAD!!!!!!!! the sorry ass TWRP file is corrupt. every process has went smoothly except for this bs. are there any twrp files for sprint that arent corrupt? the mods shouldve updated this thread to warn people. now im stuck without a goddamn phone. very pissed off!!!!!!!!!!!
[LG V20 Guides, News, & Discussion] twistedvip:
This is the exact twrp.img that I flashed onto my phone without any issue. Try and use this. If it still doesn't work then I'm going to assume it's something on your end with your computer.

lets say it is my computer, what can i do to make everything work? when i go through step 3 using fastboot... it seems to work. everything appears to flash but TWRP.
[LG V20 Guides, News, & Discussion] twistedvip:
What's the exact error message that is displayed when you do 'fastboot flash recovery twrp.img'?

I'm not sure if maybe there's some kind of A/V blocking that file? I don't know why flashing your boot.img would work, but the recovery doesn't. Can you possibly post a screenshot of your cmd prompt/terminal with the command entered and the response echoed back?
[LG V20 Guides, News, & Discussion] MPH33:

Pleae dont accuse files as being corrupt from the first post. I have checked the file itself and it is 100% working. It sounds to me like you honestly dont know what you are doing. have you tried MANUALLY typing the command as [MENTION=6817711]twistedvip[/MENTION] mentioned? or only using the step3 file?

The full command to flash twrp is

I know you're freaking out. I'm just popping in for encouragement.

It's going to be OK. You're almost definitely not bricked.

There's good people here. They'll help you get this figured out.

Don't panic.

I'm not familiar enough with everything to help besides encouragement but I've been following this entire thread and tons of threads with people with different issues and I think I've maybe seen 2 at the most that actually managed to brick.

Seen a lot of panics but just as many solutions.

Looking forward to seeing your... "omg it's fixed!" post...

You'll get it!

So i followed everything to the "t" (or so i think) but for some reason the phone will not move past the AT&T bootup logo. Also, if this is for H910, why did it convert my phone to US996? Did i f*ck something up?

edit: dumba** me realized that the stock android rom has gone. gonna flash deODEXed stock rom and see if that does anything

[LG V20 Guides, News, & Discussion] TGtheImmortal:
Hey All,

On the Sprint Variant of this phone and just had a question.

How long did it take all of you after running step three to get onto the main lockscreen? My phone seems to be stuck on the LG loading screen, making it impossible to "adb reboot recovery", due to the device being listed as "offline" when running "adb devices". Everything went smoothly and correct with the guide as far as I could tell as I had no errors other than the aforementioned flatland flash errors.

EDIT: Followed [MENTION=4591212]me2151[/MENTION] 's post regarding slow boot times, flashing boot2 and it immediately fixed this issue. However, it kicked me straight through to boot up with a secure boot, this before I even had a chance to reboot into TWRP. Any help?

EDIT 2 : Was able to get it to work. Flashed back to boot1.img, pulled cord and battery, put in battery, plugged in cord (phone should auto boot up), whilst on the FIRST boot up screen you have to be spamming "adb devices", until your device populates.

In my experience it would only stay online in ADB for ~5-10 seconds, so have "adb reboot recovery" either copied, or already input to force your device out of this boot loop. It should reboot with the red triangle, hang up for a minute, then boot into TWRP!

Cheers [MENTION=4591212]me2151[/MENTION] for the root method, it is much appreciated.

Do you have a donation button to help you acquire a new laptop?

EDIT 3: I would also like to note that I skipped over the Sprint stock rom entirely, and flashed straight to " [LS997] Stock/De/odexed/Modded/Magisk" by [MENTION=4731846]Team DevDigitel[/MENTION] with no issues whatsoever. I did, as a precautionary measure follow the guide to fix 3g/texts, but all of my settings were already correct.

rom flashed. but it wont stop booting into TWRP which doesnt make sense because i made sure the system wasnt encrypted. went to wipe>format data like 8 times and same thing. Called Asurion and told them the device they sent me last week was defective and theyre sending me a brand new one. :laugh:

They throw the used ones out anyway.

[LG V20 Guides, News, & Discussion] gretschpr:
Hi, i have the AT&T variant H910. My device is rooted using this method. I recently tried to flash an AOSP ROM and it didn't boot so I tried to go back to the ROM I was before (WETA) but now the phone won't boot up. I can go to TWRP and flash with no problem, but it won't get past the boot animation screen. I tried Weta and extreme syndicate ROMs with both konverged and werewolf kernels and it stays in the same screen forever. Can anyone help me out? The stock H910 kdz is not an option since it's not available. I was thinking of flashing the stock US996 kdz but I don't want to brick my device. Any help would be appreciated!
[LG V20 Guides, News, & Discussion] SteinerCS:
You did nothibg wrong

You need to do this then reboot

*****VERIZON USERS******

It has come to my attention that some users have encountered abnormally long first boot time(over 20 minutes before first time setup)

To resolve this issue:

Boot into bootloader by pulling the battery and reinserting it and holding VOL- and phugging in the phone. then typing:

Code:

fastboot flash boot boot2.img

fastboot reboot

**************

It has to do with the december update

I had the same problem when I rooted my phobe with the current AT&T OTA update

Try searching the forums on the V20, this thread is for the discussion and troubleshooting of the DirtySanta exploit for root,
[LG V20 Guides, News, & Discussion] daw41:
Since you want to argue semantics let me rephrase I rooted with dirty Santa exploit for root for some reason after rooting with dirty Santa exploit for root my stock messenger is no longer working if someone could upload their stock messenger app for the LG h910 AT&T Edition so that I could rule that out in my troubleshooting endeavors I would greatly appreciate it.
[LG V20 Guides, News, & Discussion] MPH33:
I tried this method just now and it says waiting for device and nothing happens. To start this I remove the battery press volume low plugged in USB device to go into fastboot. Then I typed in this command it looks like it's trying to work but it just says waiting on device. Do you have any other suggestions. This appears to be promising like this could work but I don't know how to make the computer recognize the device when the phone is shut all way down halfway into fastboot mode
[LG V20 Guides, News, & Discussion] TGtheImmortal:
It sounds like the fastboot drivers aren't being recognized by your PC anymore.

From the OP

When the phone is in fastboot mode and plugged in, does typing "fastboot devices" return anything?

These are the LG Mobile Drivers. (Honestly not sure if you need them, I got them anyways)

Here is a link for the Latest Windows Platform Tools.

I rooted earlier in the day and did not have any problems with the TWRP file. I did run into other issues however, which I detailed in this post.

Good Luck
[LG V20 Guides, News, & Discussion] me2151:
As others have stated its because your fastboot drivers are not installed. Since it was working before(kind of) I'm going to guess you are using a different USB port now. Drivers are reinstalled when a different port is used. Either try going back to the old USB port or try to reinstall the drivers from device manager.

You are spot on. Thank you for the help. You asked about my donate button. There is a donate button around my name that says donate to me. It is not visible on mobile(XDA thing) if you still do not see it on computer click my name like you would to send a pm and it should be at the bottom of the list.
[LG V20 Guides, News, & Discussion] KingRoot:
Yes
[LG V20 Guides, News, & Discussion] me2151:
From power off manually enter twrp by doing vol- and power until you see lg then only let go of power then hold both again until you see factory reset. Select yes twice then twrp will boot. Once twrp is booted make sure data and system are mounted then go to reboot system.
[LG V20 Guides, News, & Discussion] KingRoot:
Tried this. Computer isnt detecting it anymore. Plus after rooting, the img file it pushed turned my phone to US996 from H910 so i believe my phone is partialy bricked because if it. Im not worried about it anymore i will have my replacement V20 tomorrow.
[LG V20 Guides, News, & Discussion] me2151:
That's normal. Not even remotely bricked
[LG V20 Guides, News, & Discussion] KingRoot:
Thats not the problem. I made sure it was mounted when i booted into twrp the first time. Its whatever tho. Insurance us giving me a new one tomorrow for free. Told them the one they sent me last week to replace my dead g3 was defective LOL

Im just going to clarify this

Fastboot drivers are installed correctly

I didnt change usb change ports.

Phone doesn't boot into anything but recovery

System and data are mounted

FASTBOOT DRIVERS ARE INSTALLED

Next?
[LG V20 Guides, News, & Discussion] emdroidle:
This should be the same terminal window as you ran step1 in. This will be a prompt from `adb shell` and not your desktop/laptop. One way to tell you're at the correct prompt is the prompt will start with "elsa" (LGE's code name for the V20).
[LG V20 Guides, News, & Discussion] me2151:
I didn't say one thing about fastboot to you? I was talking to the other guy about that. I just told you the steps to fix a recovery loop. You are refusing to actually do the steps. That's your own fault. Your phone is not bricked. You just don't want to do the work. Recovery loop has been known since the beginning. Its a twrp issue. Not a root or dirtysanta issue. Follow the steps I said before.

[LG V20 Guides, News, & Discussion] me2151:
That fine. the main part that fixes it is going through the factory reset key combo. if you get to twrp without that right now no changes will happen. you MUST go through the key combo for it to work.

Well I give up on this phone I tried everything to get TWRP to upload and it just refuse to do it I mean I tried everything. Three days straight of complete failures. This will be the first time I've ever rooted a phone and was unable to fully complete a route. This is why I love Samsung. Their so easy to root without all the unnecessary drama. My computer fully recognize this phone I uploaded the LG drivers I did everything right I don't know I'm extremely disappointed this isn't my first time rooting I've rooted every Android phone I've ever owned except for cheap throw away second-hand smartphones. I also tried using every USB port on my laptop and it's still did not work I've never seen nothing like this before. It appears to not be that difficult but I think the toughest part of this route is getting TWRP flash to the phone. That by far is the most difficult which should be the easiest.
[LG V20 Guides, News, & Discussion] Uamore6:
When I rooted my phone at&t version US996 I followed each step. However I do remember I got stuck and not being able to get into TWRP. If I remember correctly, I opened up a command prompt on my pc, then connected the phone where I saw it recognized by device then gave the command to reboot, then reboot into recovery. Then hit step 3. And then I got twrp. Hope this helps and someone can fine tune what I did to make better sense for you.
[LG V20 Guides, News, & Discussion] Cubit33:

Yup, if you can avoid battery pulls and the phone dying, just boot it up unplugged and it wont vibrate.

If the battery is pulled, or the phone is turned on while plugged in, it will vibrate. Other than that its normal

After step 1 of the Flashing TWRP section, my phone boots to a secure start up screen even though i did not have a password on the device. I have tried reflashing twrp, reflashing the boot image but this keeps happening. Anyone know how to fix this?

I searched around but didn't find anything that fit my issue.
[LG V20 Guides, News, & Discussion] mitbit2k3:
From the OP ...

*****ALL USERS*****

If you encounter a "Secure Boot" Password then booting the first time you did not Format data properly.

To reiterate: To properly decrypt the device you need to boot into TWRP and go to WIPE->FORMAT DATA and you will be prompted to type "yes" to format and decrypt.

[LG V20 Guides, News, & Discussion] Ravreet_Kang:
It says in the OP to wait for the main lockscreen then reboot to recovery. I haven't even been to TWRP yet. Still on step 2. What you quoted comes after the steps which are performed in the recovery. (During step 5)
[LG V20 Guides, News, & Discussion] UPSGuy:
I've previously rooted with dirtysanta but it's been months so I don't remember the issues I ran into initially. I was forced to return to stock to resolve an issue on my VS995. All was going well until step 3. It rebooted to an LG screen, then a verizon screen and it's been there over 20 minutes. How long should I wait? P.S. There is a note about long first boot in a later step and gives a file to flash, but that's in a later step. Anyone?
[LG V20 Guides, News, & Discussion] daw41:
Have you completed step 3
[LG V20 Guides, News, & Discussion] UPSGuy:
Yeah, I ran step 3 and it rebooted but never got to the lock screen. its been over 30 min.
[LG V20 Guides, News, & Discussion] daw41:
It did that to me Check and see if your adb recognizes the device if it does ( which mine did) type adb reboot recovery and it will boot into twrp.
[LG V20 Guides, News, & Discussion] UPSGuy:
Yes, adb recognizes the device under adb devices, but adb reboot recovery did nothing. It stayed on the verizon loading screen for over 40 minutes. I finally pulled the battery and tried flashing the file but after that I get the secure startup screen...so I'm now returning to stock again and about to start over. 3rd time trying this tonight.
[LG V20 Guides, News, & Discussion] daw41:
Did you try manually booting into twrp
[LG V20 Guides, News, & Discussion] UPSGuy:
Disregard....It was a PEBKAC error. For some reason I forgot to copy the twrp file into my adb directory....derrrr.
[LG V20 Guides, News, & Discussion] Ravreet_Kang:
This was exactly what was happening to me it hanged I flashed boot2 then secure startup came up. What I did was pull the battery then hold volume - down and the power button when the LG logo appears let go of the power button for 1 sec then hold it again (volume button still held when power released) then you should get to a screen asking if you want to factory reset use volume keys to select twice then eventually you'll be in twrp. (Might take a while and might loop once or twice) Go to wipe, format data, type yes, then reboot. Once you're back at the initial setup run through it then enable USB debugging then continue where ur device hanged (ADB reboot recovery)

EDIT: Lol just saw u fixed it well anyways im going to leave this here if someone encounters the same problem as me
