V20 Vibe ;]

Blarrrgg...glad I made the choice to start on page one and read through ever comment in the thread....the answer to my question was BOUND to come up amongst these posts. So I got his device rooted essentially...I just don't feel great about it and want to repeat the process from step one. Idk if that is over kill or not...he said there are some lag issues but that's about it. Now he's ready to go balls to the wall and get a custom ROM/ Kernel going....I believe that's being too adventurous given our skillset in this is notably limited...but it's his phone so it is his choice.

Do you think it would be unnecessary to repeat the full process when his only issue is some lag? :confused: THANK YOU....I will be keeping my word and cough up my pledge the second I can I promise :angel:
[LG V20 Guides, News, & Discussion] me2151:
Which kernel is he using?

EDIT: If he is still using Boot2.img Tell him(or you can yourself) to flash the Konverged Kernel. That fixes most of our issues including lag.
[LG V20 Guides, News, & Discussion] repsol_23:
Maybe. But I had the fingerprint set up the day I got my v20. I didnt root until just days ago so I ran unrooted for nearly 2 months. Not once do I recall having to enter my pin on reboot, but then again its new years and I may have already killed that brain cell. Lol.
[LG V20 Guides, News, & Discussion] me2151:
Yea its supposed to do that. I have my v20 stock right now and i even checked for ya. Still asks.

Glad someones partying lol. Im stuck at work.
[LG V20 Guides, News, & Discussion] repsol_23:
Wait. Let me clarify. I no longer have to enter my pin at the white screen prior to bootup. That used to occur prior to root. I meant that after I boot and get past static screen and go to turn on my phone for first time. Then my finger print will not work at all. I'm prompted for my pin instead. Hope that makes more sense.
[LG V20 Guides, News, & Discussion] me2151:
OHHH lol. thats secure boot. theres an option in settings if you wanna turn that back on.
[LG V20 Guides, News, & Discussion] repsol_23:
Sorry to hear your stuck at work. I dont party as I'm an old fart by my kids standards. Lol. Thanks for the hard work and may you and your family have a great new year.

This method or a method like this can be applied on LG G4? is it possible
[LG V20 Guides, News, & Discussion] Emilicious:
So we ended up going through all the steps again, which was very comforting for my mind. As "simple" as the instructions appear, the first read through seems to be a bit of a hurdle. We are running into the issue of his screen going staticy (something I am noticing may be somewhat a common issue...so I am reading through the thread to see if I can find the solution. AWESOME WORK EVERYONE! When I grow up I wanna be just like all of you
[LG V20 Guides, News, & Discussion] me2151:
The static screen issue is due to the differences in the Device tree. We will be attempting fixes but the CM/LOS team already found a fix but it isn't working for non AOSP roms.
[LG V20 Guides, News, & Discussion] me2151:
Not unless you guys have a debug aboot file. you cannot use our files or you will brick.
[LG V20 Guides, News, & Discussion] emdroidle:
I've had the pure LG sources for a while, no need for search engine to find those. I'm looking for information on the kernel and tools used for Dirty Santa. Finding these is hazardous via search engine, rather a lot of unrelated stuff shows up.

Searching for "dirty cow", among other things I find, not one, not two, but in fact three apparently independent implementations on GitHub. In total those have around 1000 forks, though only 41 of those have activity on GitHub.

According to [MENTION=7479791]Honestly Annoying[/MENTION], here, the source code had to be "sent". No where on this thread are there any pointers. If it is public could a URL be provided?

There are also the "reserved" posts at the start of this thread. I was left with the impression there were plans to release technical details. Any plans yet?

Uh, slight GPL issue here. I imagine the delta from LG's stock source is tiny, but I would like to know how what any differences are (our tastes in debug level may differ).

That is good to know.
[LG V20 Guides, News, & Discussion] onotor:
But it's not possible to unlock LG G4 in unofficial way??
[LG V20 Guides, News, & Discussion] me2151:
I only send the source for the dirtysanta file. theres nothing to download for it. its literally a few DD commands and some other minor stuff for logging. The other files are available on GitHub in other locations. Where do you get the impression we were going to release technical information?

Your link Number 1 is the dirtycow files we used.

the "my-run-as" file did not have a source available. just a download link.

Im not quite sure why there were so many "Reserved"Posts as I only did the first one and I have now used it.
[LG V20 Guides, News, & Discussion] Honestly Annoying:
I just sent the devs a PM asking for the code to be shared as I had an idea and specific use for it. If they do end up sending it to you, make sure you get permission from them before you start posting/devving things publicly...

TO ALL LG G4 USERS POSTING ON THIS THREAD AND OTHERS:

Please stop trying to make this thread about the G4. I will answer every question you've been asking in this one comment

1. No, this method will work for the G4/ANY OTHER DEVICE EVER

2. No, this method cannot be modified to work for your device unless you have official userdebug firmware from LG for your device

3. No, I/other devs will not attempt to find root for your device as there is no way for us to do that.

Please stop cluttering threads and making them about devices other than the one it is intended. If you have questions about your device, make a thread in the specific forum intended for you and it will be answered there.

/end rant
[LG V20 Guides, News, & Discussion] emdroidle:
Indeed, you never wrote anything about releasing technical information. I was kind of hopeful and what you've written here is quite valuable (I had some good guesses, but confirmation is high value).

So this was the source for `dirtycow`. When did you retrieve the source? There isn't that much activity on the repository, but enough for the differing versions to be a concern.

Could you point to where `my-run-as` came from? I'd like to know more about what it does.

Thank you for the information!
[LG V20 Guides, News, & Discussion] me2151:
The dirtycow exploit does not changed on the repo. as for the "my-run-as" file. It was found here

Ah shiiiit, I think it's bricked. I mean it feels destined to end up that way. The VZW repair tool keeps losing recognition of it (I know I know, we should expect to be able to go back to stock)

Don't use VZW repair tool. use LGUP and uppercut for returning to stock

All time static screen

Got to step 3, installing TWRP, and must have interrupted the process at some point. Now the phone boots and does everything fine (I can tell because there are glimpses of actual screen items/movement/unlock) but the entire thing is static colors, including 2nd screen. Any ideas? A few horizontal bars show the regular screen behind the static, but that's it.
[LG V20 Guides, News, & Discussion] me2151:
You didn't read the whole guide(theres a fix in the second post).

.

it works if you place it in the rom under system/priv apps then flash it.

also need to go under settings and apps after and go to the app and put all permissions to yes
[LG V20 Guides, News, & Discussion] Artimis:
How long did you let it sit on the static screen? If data or dalvik was wiped, caches need to be rebuilt. In this case, it will need to sit in the static screen for anywhere between 10-15min while caches are rebuilt and you won't be able to turn off the displays.

If you do a reboot or pull the battery during this process, it may screw something up and the process will probably restart on the next boot.
[LG V20 Guides, News, & Discussion] me2151:
Go to bootloader and type

fastboot erase userdata

Then do

fastboot flash boot boot1.img

THEN

fastboot reboot

It will reboot.

wait 5 minutes(it will look frozen) and type

adb reboot recovery

once in twrp follow steps from step 3(twrp instructions)
[LG V20 Guides, News, & Discussion] Team DevDigitel:
trying myself to get out of this boot loop also,

already tried ( fastboot erase system,cache,userdata,boot,recovery )

then replaced the boot.img , replaced the recovery and then booted into recovery, wiped and formatted, installed rom and still stuck on endless bootloop... hmm.... gonna keep at it. cant be this damn hard to get out of this
[LG V20 Guides, News, & Discussion] anon389389109:

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:

fastboot flash boot boot2.img

Been following this thread just reading up on everyone's experience rooting this phone. I have the Sprint variant and would like to know, from those who have the same phone, to give me their input. Did anything break after rooting the phone? I read about the issue with the second screen, was this due to rooting or just because of the custom ROM? I'm only concerned about rooting right now to get rid of bloatware and getting Titanium Backup to working again. I don't think I want to try any custom roms at the moment. Also, is there a way to flash back to stock without root just in case I need to get the phone replaced?
[LG V20 Guides, News, & Discussion] Emilicious:
**UPDATE** okie dokie so I can 100% confirm that the Verizon variation can be restored back to stock! With the information [MENTION=4591212]me2151[/MENTION] provided about Uppercut/ LGUP and this guide and I got the VZW .kdz files here.

I followed the guide by [mention]ahlok_hk up until it says run LGUP[/mention], instead at that point I ran the Uppercut program that [MENTION=2684188]autoprime[/MENTION] provides in his XDA guide.

The Question​

What are the steps needed to take to give the phone life again?

The "Deets"​

When we try to boot

Has a green screen of RAM dump failure(?)

I can get into fastboot mode and the computer does recognize it

What I have Prepared to Fix His Phone

This Firmware download for the Verizon LG V20

All the files for Uppercut, LGUP, and the LG Drivers found on this XDA thread

Also I have the LGFlashTool I think that I got from here

What I Plan to Do

Basically after my VS99512A_06_1114_ARB00.kdz file is finished downloading I was planning on going into download mode, install drivers again from the LG Drivers .exe file, then opening the Uppercut.exe file to trigger LGUP and hope that it a) finds the phone and b) finds the .kdz I am downloading, and for the last step: win :good::cool:

Random Extras​

I told him what needed to be done in order to save the phone before I fell asleep (using the LGUP/ Uppercut action-dealio you had suggested [MENTION=4591212]me2151[/MENTION]) then I woke up and he was asleep and his phone had that new develop of the RAM green screen of, what feels like, phone death. I did a lot of read-through, but was super tired so didn't do it very thoroughly and had downloaded a CRAP ton of images and a system file for a different variant. Correct me if I am wrong, but it seems like a lot of people are getting to stock or saving themselves from a brick by using other' stock's (i.e. using a v10 stock or g5 etc.). I was slightly confused reading through this thread at times because a lot of questions pertained to other LG generations entirely. So I have just guessed that maybe their stock action can be somewhat interchangeable if a brick rescue is needed?
[LG V20 Guides, News, & Discussion] 666syco:
Yep can confirm 12A is ok to unlock and root. Was up all night doing it and playing with the phone now I'm back to just dirty Santa and root with the bootloader unlocked.

Now I looked in the forms I don't see no kernels for just the verizon model V20 is that correct. I'm asking cause I want to give my phone some added pep. Debloating helped but I got this lag that feels as if its not going to give up. Thanks for all the hard work guys made my upgrade well worth getting.

What is CM/LOS :confused:? I wish my knowledge on the vocabulary for all this were more impressive, alas I am still in the beginning stages of it all...so sorry if I appear extra nubcakey asking that question. So then would a custom ROM technically fix that issue if it were compatible with whatever it is that's working? If so does anyone know of a custom ROM that is working 100% and fixes the static screen? EDIT I just realized you guys let everyone know of a temporary fix on this thread haha and for anyone who wants to know this custom ROM/ Kernel is working :cool::highfive:

So I saw that it looks like some variants now have a return to stock option. Does anyone know if the AT&T H910 has a KDZ available, yet? If not, any thoughts on when/if one is expected? I am really looking to get mine repaired since it exhibits problems with basically everything related to audio. This includes phone calls of course. When on the handset the other person can hear me fine but speaker crackles on my end. When on BT, both sides sound terrible.
[LG V20 Guides, News, & Discussion] dricacho:
Thanks for the reply. That is my observation as well with the Sprint variant. As is now, stock and unrooted, the phone has a few annoying quirks. One that really annoys me is how it handles external storage. I keep documents in there and I update them as I go. When I try to update any file, TXT or office documents, it will not allow me to save the document into itself. It wants me to rename it. But I am able to read files from it. My camera app saves photos into external storage and there's no issue there. I've checked permissions, even reformatted the microSD card, to no avail. It is set up for portable storage. Looks like I'll sit and wait for now, until more progress is made.
