[LG V20 Guides, News, & Discussion] DarkPaladin23:
So I've come to the realization that there are some issues with my device that would require a repair/replace scenario. I'm on the AT&T H910. The phone speaker sounds awful (clicking and crackling even at low volumes), Bluetooth calls drop in and out and are loaded with stutter. Bluetooth music and headphone jack both sound bad. Muted and depth less. Since we can't currently return to stock, does anyone have any thoughts?

Edit: basically my phone fails at being a phone. Maybe hard brick? Never run into this before.

[MENTION=4591212]me2151[/MENTION] Sorry if this question is rubbing salt on a wound. It's not meant to.
[LG V20 Guides, News, & Discussion] me2151:
You can make the phone bricked like mine is. Mine looks like a update brick/bootloop. I don't get any warning except in recovery and recovery won't load. I have an appointment with sprint tomorrow to get my phone replaced. Im claiming that "i did an update and now my phone won't boot. I read online that i can try to factory reset in recovery mode but it just says its corrupt." And so far they have bought it. I will tell you tomorrow if they accept the phone for replacement and we will go from there.

Tried installing, goes through with an error at the end of being unable to mount /system.
[LG V20 Guides, News, & Discussion] me2151:
In twrp go to mount and make sure system is checked. then try again
[LG V20 Guides, News, & Discussion] nahepler90:
I go to mount and system will not check. And I tried both on internal and external.
[LG V20 Guides, News, & Discussion] Honestly Annoying:
If people want to talk about debugging that LAF partition commands I have a chat I can add you to. PM me and I'll send you the link, as we have a user who has achieved some pretty fantastic work on this already.
[LG V20 Guides, News, & Discussion] nahepler90:
So I got supersu to reinstall, only way I could get system to mount was as shown if that is correct as read only? And am still getting the issues with root browser/explorers.
[LG V20 Guides, News, & Discussion] slickdaddy96:
Has anyone taken the sprint update pushed out and still been able to using this root method?
[LG V20 Guides, News, & Discussion] elliwigy:
the question is, what is the security patch level and/or does dirty cow still work?

those can test dirty cow withought rooting their phone... should be safe just to test but if security patch is beyone Dec. 1st it might be patched
[LG V20 Guides, News, & Discussion] MANDROIDS:
Sprint - LS997

Is it the rooted rom or the Konverged Kernel that removed PRL updates and ## codes?
[LG V20 Guides, News, & Discussion] nahepler90:
Dinked around with a few ideas and got my problem fixed! Heres what I did.

1. Made a backup of system in twrp just in case.

2. Formatted system in wipe > advanced > and only checked system.

Panicked because I thought I bricked my device, wouldnt boot farther than the lg logo,

(next steps might be unnecessary but I panicked and tried them lol)

3. still had fastboot access so I repeated step 3 in the root method.

4. Reflashed boot2.img

5. Rebooted to recovery with volume- power, release power while keeping volume- at lg for a second then repress and hold power. Yes twice to get to recovery.

6. Restored system backup. (was able to fully boot now but with lag)

7. Reflashed konverged kernel.

And everything is working perfect now and I have my r/w ability and can mount system in recovery without having to select mount as read only.
[LG V20 Guides, News, & Discussion] elliwigy:
im sorry im of no help but the creator of dirty santa has Sprint and had 0 issues you and asmall number of other sprint users have.. he only bricked trying to revert to 100% stock sprint..

so i understand, you have bad receptionso you feel you need a prl update or is the phone actually prompting you to update prl?

does *228 not work on sprint phones?

my impressiong are that a lte capable device updates prl on each reboot automatically.. with vzw and usc for example theres no need to perform a prl update as its refreshed on each reboot of the device so long as the sim card is inserted.

Have you tried contacting sprint? i know they can "refresh voice" and "refresh data" on their end as i work for a cellular company and know these things... lte devicee typically 9nly need themeid and sim card number provisioned in the billing system and thats it.. this is how you can swap sim cards between phones without calling them as itwill activate and sync up on each reboot
[LG V20 Guides, News, & Discussion] esqueue:
The thing is that neither are made for sprint.

Our rooted sprint phones are missing a few features such as Wi-Fi calling, FM, PRL updates, HD calling, ##codes and a voicemail program.

If someone uploads a Stock system.img and boot.img, there is someone making roms that should include these features. He has been asking for those files. He has already made them for Verizon, AT&T and others.
[LG V20 Guides, News, & Discussion] elliwigy:
has anyone by chance got an update notification on a rooted/unlocked ls997?

unfortunately (not sure why) i believe [MENTION=4591212]me2151[/MENTION] had to modify the stock deodex us996 rom to be closer toa sprint device to get everything to function.. other variants worked without flashinganyadditional rom.zip..

i believe [MENTION=4591212]me2151[/MENTION] has the Sprint ZV4 image but was apparently skipped entirely by Sprint.. not sure if [MENTION=1325580]Tilde88[/MENTION] can build it and kernel without the ZV5 source (unless source was released and we missed it)

my concern is that [MENTION=4591212]me2151[/MENTION] didnt have that issue and was running grwat (better battery than my vs995) without updating prl or anything so why are some having this issue?
[LG V20 Guides, News, & Discussion] esqueue:
I have no idea. Mine is actually running great and I am getting awesome battery after the konverged kernel. It's just that many features are missing. The only thing that I miss is the voicemail program. Mine shows that I am missing 9 calls. The only way that I temporarily reset it is to clear out call services data. That works temporary. I used to use the voicemail program without having to call my phone number but the version that I found on XDA doesn't connect and authenticate. I can't set it to work on my phone or even update for some odd reason.
[LG V20 Guides, News, & Discussion] juggalo483:
is there a command of any sorts that i can use or run that will get me from download mode into recovery on the sprint LS997?

Anyone on the Sprint version have any issues with receiving text? I am okay with sending but I am not receiving.

I searched through the threads to see if anyone else had issues but couldn't find any...hopefully I didn't miss it.

[LG V20 Guides, News, & Discussion] DarkPaladin23:
I'm on AT&T but I did have an issue receiving texts. It was several hours and 2 or 3 reboots and test messages later that I finally received a reply to one I sent. Until that first sent one was replied to I was not receiving any though I should have had 7 or 8. Nothing special on how to fix it. This was on stock messaging app.
[LG V20 Guides, News, & Discussion] Ryuk359:
I've got a big problem. I had a few minor issues so I restored my nandroid backup. Completely forgot about my pin code and now the one I put in isn't correct. I know thats fairly common what isn't is I can't get into recovery to fix it. I would use adb but when I restored it ****ed up my auth keys. All I can do is look at a lock screen and go into fastboot by doing the volume down and plug in. can't get it to do anything from there tho just says waiting for devices. please help [MENTION=4591212]me2151[/MENTION]

Im lost on step 4.. excuse me its been a while since i have had to work for a root lol
[LG V20 Guides, News, & Discussion] BackCheck:
I had the same issue restoring from a backup in TWRP as well. The only way I found to reset it was 'fastboot erase userdata' but this resets the phone to default.
[LG V20 Guides, News, & Discussion] idkwhothatis123:
Stuck at vzw boot animation for a while now. Like 20+ mins. what should I do?

edit: clarification. Stuck at boot animation after step3.bat. Have not gotten to twrp to wipe data yet.
[LG V20 Guides, News, & Discussion] Ryuk359:
Got mine handled. I did something really scary and stupid with a 99% failure rate but it worked and I'm running better than ever.
[LG V20 Guides, News, & Discussion] BackCheck:
I had the same situation. After a few hours I had to pull the battery. It would never boot past the VZW logo and I thought it did not start adb. Adb does run for a brief moment, I made a batch script to issue the adb reboot recovery command in a rapid fire loop and this got me to TWRP. From there everything went more or less as the instructions say.

:loop
adb reboot recovery
goto loop
[LG V20 Guides, News, & Discussion] idkwhothatis123:
Okay. got me into twrp. followed the steps in there. now my devices is booting again. fingers crossed. Thanks!
[LG V20 Guides, News, & Discussion] shoes22:
Does anybody know what kind of secret sauce is in the stock kernel that makes wi-fi calling work on Verizon? All other kernels for this phone break that feature on the VS995. I’m going to work on a kernel mod that makes it work, but in the meantime If has anyone has insight or resource links on this it would be very much appreciated. And if anyone’s already looked into this, PM me and we can collaborate. I have some ideas. There’s a lot of dev documentation for this for T-Mobile variants of other phones, but not so much for Verizon.
[LG V20 Guides, News, & Discussion] idkwhothatis123:
I'm good to go! Thanks bud!!!

Side note: This was hands down the scariest root experience I have ever had. I thought for sure I bricked my device at least three different times. Thanks all for the help and thanks to the dev's who made this possible!
[LG V20 Guides, News, & Discussion] Artimis:
Does the kernel from the VZW "not so stock rom" do WiFi calling? I asked the question in that thread but did not get a response.
[LG V20 Guides, News, & Discussion] shoes22:
I'm not running that ROM but I wouldn't bet on it...the kernel for that ROM is an entirely different version altogther.

While the ROM may have been based off a stock Verizon rom, the kernel definitely isn't, which is the same issue that broke WiFi calling on our stock 11A Verizon ROMs after dirtysanta, because it loads the US996 debug kernel to make it work. The VS995 has kernel specific code that makes WiFi calls work.
[LG V20 Guides, News, & Discussion] streetpounder:
I'm on the ATT version and ours is similarly broken. The icon lights up and such but the actual feature is borked. I hope you and the others make a breakthrough as it will likely help on the other variants as well. Godspeed!
[LG V20 Guides, News, & Discussion] Artimis:
Thanks, I figured as much.

If I'm not mistaken, the Wifi calling feature works for a stock US996 phone on Verizon so I wonder if there is some kernel source available for that variant to compare with the debug kernel source (if VZW source isn't available).
[LG V20 Guides, News, & Discussion] AthieN:
In total, you will be downloading three zip files from the main page. They are: v20-root.zip, SuperSUxxx.zip and LS997-deODEXd-signed.zip...

Only extract v20-root.zip, not the others...

Does that make sense? If not, shoot me a PM and I'll help you out.
[LG V20 Guides, News, & Discussion] Tilde88:
Dev of the notsostock rom. The kernels i compile are compiled per device, per defconfig.. Confused about the question.

I hadnt realized that wifi calling was down for h910 ans vs995 on my roms. If it is, my bet is its due to the modules built for the kernel. The kernel source modules dont match the ROM version. But i only have the 1 stock ROM for vzw, same for at&t
[LG V20 Guides, News, & Discussion] UPSGuy:
First, thank you very much for the nice work on this. I really appreciate it.

I'm running a verizon v20 (vs995) and have successfully completed all the steps. A couple quick things:

1) Am I going to get the non-stop vibration and the your device is corrupt every single time I reboot my device forever?

2) Any bluetooth fix? Whenever I pause my bluetooth stream from the phone while the screen is off, the bluetooth won't "wake" back up. Then once the screen is powered back on the bluetooth stream is choppy and garbled until the bluetooth device is rebooted and sometimes you have to turn off bluetooth on the v20 too to get it to work again.

I haven't had time to root my LS997 yet. Sprint sent an update but I have not taken it yet. Should I avoid the update until I root?

Do you have plans of maybe making a Youtube Video of these instructions?
[LG V20 Guides, News, & Discussion] AthieN:
Well, since I've already rooted my device and it's the only one I have, I don't see how I would be able to. Lol. But if somebody would like to make a video using these instructions, they definitely can. All I ask is to give credit where credit is due and I'll do the same. :)

According to me2151's post that he is moving on to an Axon 7, I was hoping other developers might step in to continue the project.
[LG V20 Guides, News, & Discussion] me2151:
i Bought an Axon 7. That doesnt mean im leaving you guys. I got my replacement v20 today so ill be back in the game. I am going to attempt an alternate method of providing root but it WILL be much more involved than this current one. but if it work the it should work on dirtycow patched devices.

Word of warning: Any sprint user who is on a version higher than ZV3 then DirtySanta will not work as they patched it.
[LG V20 Guides, News, & Discussion] raresoul77:
Much more involved? Seems like things are moving backwards. If anything, I was hoping more for an easy way to root .

keep in mind that Android is becoming more and more secure and its becoming more and more difficult to find working exploits.
[LG V20 Guides, News, & Discussion] me2151:
I though it might. It was unreleased to most I have a KDZ of ZV4(its unusable) thats dated DEC 1 meaning it didn't have the dirtycow patch(that was done DEC 5) but since it didn't get released I didn't mention ZV4
[LG V20 Guides, News, & Discussion] KedarWolf:
I got dirty santa kind of working on a Freedom Mobile H915, except it has no signal to the phone and doesn't detect the SIM. It's rooted, just can't make calls. Someone else rooted it as well and flashed the h915 modem, never helped. I wonder if there would be a way to get it to detect the SIM. :confused:

I don't think I'm going to try again. In efforts to revert it back to stock and get the signal working I bricked the phone. My only saving grace is I have an extended warranty on it and can get it replaced with a subtle approach. :eek:
[LG V20 Guides, News, & Discussion] me2151:
We already discussed the H915 does not work right. You most likely got an app crashing every 5 seconds and no sim reader.
[LG V20 Guides, News, & Discussion] qstarin:
Ah snap. I thought it was just the security patch level that determined if the exploit was patched and that any v20 with Nov 1 security patch was good to go. I see my software version is ZV4. Sounds like I'm SOL for now then, bummer :( Nevermind I should've finished reading the thread.

I'm surprised we even have an exploit. I thought for sure this was the generation I either had to buy an open, unlocked phone from the get go or resign myself to a locked down, un-rootable device.
[LG V20 Guides, News, & Discussion] emdroidle:
I thought you were joking when you wrote that.

If the source isn't available, notify the FSF since that would be a severe GPL violation. I'm pretty sure they know the rules and thus make source available, though they can do things which make life painful for developers.

There were some plans to start releasing technical information, might I inquire as to plans? Are how different are the debug kernels from the pure LG kernels? Just one or two kernel configuration changes to make root access easy? Is there a publicly accessible repository for the source code anywhere?
[LG V20 Guides, News, & Discussion] elliwigy:
sources are available and simple searching will find them.. in fact theres devs already making kernels from the sources..

Also, the debug kernels/files are LG firmwares, if they werent they wouldnt work at all on our device
[LG V20 Guides, News, & Discussion] me2151:
I was not joking :) I did buy a Axon 7.

The debug kernel sources are not released.
[LG V20 Guides, News, & Discussion] qstarin:
I just got an LS997 with Nov 1 security patch and ZV4 and these directions worked for me, though I ran into a couple things.

First was at step #15 it was a bit confusing that step1.bat also gave an elsa:/$ prompt. It does say to perform the commands on the phone but it still gave me pause.

On step #18 the phone didn't boot back into the system, it seemed stuck at the LG screen, it appeared to loop at least once. After waiting a while I just tried adb reboot recovery and then it rebooted to the red exclamation point/triangle and then to TWRP (actually used the bat script to run it in a loop found in this thread but it worked the first time). I was able to proceed from there.

When I got to step #22 attempting to wipe gave me an error wiping the Dalvik partition and no other other partitions appear to have been attempted. I proceeded to step #23 and then afterwards went back and cleared all the partitions 3 times successfully. Proceeded again with step #24 after the successful wipe.

Also, I don't think I saw it mentioned, but the red exclamation triangle and phone corrupt message shows on every boot (but boots fine). I also have to say that there's some noticeable lag that wasn't there stock, particularly unlocking the phone and installing apps. I read often that android "settles in" over the first day or two.. seems odd but maybe it continues to optimize. It was dead snappy from the first boot stock. Guess we'll see. I'm also getting more failures to read my fingerprint but it could've just been not as good of a scan when I set it up post-root versus pre-root.

[LG V20 Guides, News, & Discussion] repsol_23:
I have the exact same issues with the finger print scanner. When I reboot it never reads my print, I always have to type in my pin code. Pre root that was never an issue. I also get more error with my print post root but I think I will try a rescan.
[LG V20 Guides, News, & Discussion] me2151:
You need to enter your pin in the first time when you reboot. Its always been that way. Its a security thing. Has nothing to do with the root.
