Hi,

While that directory doesn't exist, I did find /data/fota/dlpkgfile which was about the size of what it's looking to install (1.1G). Unfortunately, removing that file didn't seem to help. After removing it, I rebooted but am still getting notifications every few hours about an update. Note that FOTA & System Update are still frozen via Titanium.

I used busybox's find to dump a list of all files on all the mounted file systems (at least starting from /), copied the file to a unix system where I did a search for any file larger than 1GB. Other than the US99610n.zip file I put there to install with TWRP, the only other file found was /data/fota/dlpkgfile (which is now removed).

I'd love to hear any other ideas.

Thanks!

Will this delete everything off of internal storage, or is the backup just a safety precaution if things do go south?

Edit: Also, can i go straight from 10f to 10n, i am on us unlocked 996 not us cellular, if that makes any difference

Go back to US996l0l

Is there a way I can roll back to US99610l from US99610n so I can get back my Verizon features and signal if so how.
[LG V20 Guides, News, & Discussion] feretio:
Applying the US99610n.zip file via TWRP did not wipe anything on my phone but be sure to apply your preferred root zip file with TWRP before rebooting.

I updated from 10f to 10n with no issue.

---------- Post added at 02:37 PM ---------- Previous post was at 02:35 PM ----------

Finally found it! In addition to disabling FOTA & System Update, I also found Software Update. Once I froze that with Titanium, the notifications to update my phone finally stopped. I also made sure to wipe the data for Software Update so I might try to re-enable it sometime to see if the notifications return.

Are you using your US996 on Verizon? I see you updated to 10n "with no issue". Does that mean you didn't/don't have any signal issues as described by others, including those [MENTION=4538352]yablackrob[/MENTION] has described?
[LG V20 Guides, News, & Discussion] feretio:
Yes, I'm on Verizon but I haven't really noticed any problems with the service. Then again, I don't use HD calling because it never worked well in my house.

Big thanks to dimm0k for excellent work on these packages.

Can anyone confirm that it's safe to "un-root" after installing any of these versions? I went directly from LineageOS to US99610n but I only acquired root to ensure I was following dimm0k's guidance exactly. I was going to use root access to uninstall the LG bloat but I think I'll just leave it alone since it's not really bugging me much and I've disabled most of it anyway. Since I'm now not making use of root, just want to confirm that it's safe to get rid of it but dimm0k's warnings "....so you need to be root'd before flashing this! failure to do so will probably cause you to lose root and/or lose TWRP..." make me concerned I'll lose TWRP if I get rid of root. I have no idea why that would be since I've never needed root until now. Much appreciated if anyone can provide some insight on this!
[LG V20 Guides, News, & Discussion] DrPhant0m:
Verizon released a list of GigabitLTE-capable devices, and while the V20 can't get the full speed, it is capable of using 2 of the 3 technologies, making it capable of higher speeds than all but 6 phones (and their variants). See here for details.

In the article I linked above, it says that some of the devices require an update to get the faster speeds. Does the 10n update include these improvments? I'm currently on 10h (April security), so I am starting to get the itch to update... but with the comments about verizon features being removed in the newer releases, and not being able to roll back... I've been hesitant. Verizon's GbLTE service should be available in my area, according to some related articles I've read on the topic.

Can anyone help to sway me in one direction or another?
[LG V20 Guides, News, & Discussion] nickthaskater:
What features have been removed? I'm on 10n and I don't see any negative difference.
[LG V20 Guides, News, & Discussion] DrPhant0m:
I thought some users had reported that some of the advanced calling features weren't working, or were not even available. I think HD Calling and Wifi calling were among them. Also, their reception was not as strong.

See post 93 and later in this thread.
[LG V20 Guides, News, & Discussion] dimm0k:
if I'm not mistaken, installing Magisk or SuperSU disables forced encryption at boot to allow booting of a modified system. according to [MENTION=5672995]jcadduono[/MENTION]'s original LGV20 root method, 'Warning: If you don't flash either no-verity-opt-encrypt or SuperSU, you will probably end up in a horrifying never-ending boot loop of "corruption"!'

[LG V20 Guides, News, & Discussion] nickthaskater:
I thought HD/WiFi calling were carrier-enabled features rather than on-device? In other words, they won't be available if your carrier doesn't support them.

Within my Advanced Calling options I have HD Voice, but it's greyed out (always has been). WiFi calling has only ever been accessible through a custom shortcut, and it's no different with 10n, but again, that's a carrier-enabled feature.

Reception-wise, I've not noticed a difference either way from f through n on my 996. It's poor now where it was poor originally, and vice versa.

I'd say people are mistaken or just being taken in by placebo and wishful thinking.
[LG V20 Guides, News, & Discussion] DrPhant0m:
Thanks for the update.

Does anyone that has upgraded a Verizon-connected US996 to 10n have HD calling? It seems everyone that reports on it didn't have it to begin with, so the results are inconclusive.

Also... is 10n anti-rollback? That means you're stuck on 10n, correct... with no way to downgrade? I really want to make sure beyond the shadow of a doubt that 10n is a good platform to be on, especially if I'm unable to roll back to a previous build.

Finally... can anyone comment on whether 10n includes the GBLTE update from Verizon? The update seems to have been released in early December... so the timing seems right that it could include whatever magic is needed for GBLTE connection. That's why I posted earlier today, but other interesting topics have surfaced as well.

Thanks again.
[LG V20 Guides, News, & Discussion] txenglan:
Thanks again dimm0k. I guess this must only be relevant to stock or modified-stock ROMs as I installed TWRP and LineageOS back in October and didn't root....

---------- Post added at 05:22 AM ---------- Previous post was at 05:13 AM ----------

Are you asking whether the update directly from the carrier is anti-rollback? If you already have TWRP and have rooted your phone, I assume you can flash any of the zipped packages in the OP without issue, regardless of whether you revert back to an older version. If not, I guess I'm stuck on 10n. For reference, in case it's useful, if I go to the service menu (*#LGMENU#*996# ), anti-rollback is set to "0".
[LG V20 Guides, News, & Discussion] DrPhant0m:
I'm going on the text in the first paragraph of the OP (post 1 of this thread), where it talks about 10k possibly being "ARB." If the service menu is the indicator, then it appears that 10n is not anti-rollback. Thanks for the info.

I'm rooted and have TWRP installed anyway... but coming from a Note4, I know how permanent (regardless of an unlocked bootloader, root, using Odin to flash, etc) some firmware updates can be. I was just being careful.

Is it necessary (or just recommended?) to back up the entire internal SD and perform a TWRP backup? I mean... does it wipe everything when you install it (necessary), or are you just safeguarding against issues during the flash (recommended)? Thanks!
[LG V20 Guides, News, & Discussion] nickthaskater:
It shouldn't touch the SD card, but it can't hurt to make a backup regardless.

As for TWRP, it's always good practice to make a backup before making major changes such as flashing new firmware. There's no telling what gremlins may pop up as everyone has a different set of variables with the way they've set up their devices. That said, if you dirty flash it, it shouldn't overwrite anything as far as your apps and files go beyond what's noted in the OP. That being said, a clean flash is generally the best way to go in my book.
[LG V20 Guides, News, & Discussion] DrPhant0m:
Thanks... I actually rely pretty heavily on Titanium Backup and usually clean-flash everything at this scale (ROMs, firmware). TWRP backups take up too much space on my extSD card, so I usually just keep one "baseline" backup to get quickly back to a known safe spot without having to do a full OS setup.

My phone has been acting up lately anyway, so I think a clean-flash is in my future, and I won't bother with a TWRP backup. However... backing up (the used portion of) 64GB of internal storage is a pretty daunting task, especially since it seems like so often I can't copy everything because stuff is in use. Is there a recommended way of backing it up, that isn't simply opening the phone up in Windows explorer and copying it all via drag and drop?

Thanks for the info.
[LG V20 Guides, News, & Discussion] nickthaskater:
I use a USB 3.0 micro SD adapter. Power down, pop out the SD card, put it in the adapter, pop it into the PC and copy and paste. My 64GB card doesn't take that long with speeds around 60-90MBps read to my PC's SSD.
[LG V20 Guides, News, & Discussion] DrPhant0m:
I use a card reader for my extSD too, but I meant to ask what the best way is to back up the 64GB internal storage of the V20.

I'm trying to find a good way to do it in recovery, since none of the files will be in use... but doing it in TWRP doesn't give a progress meter. I guess I can just start it at night. I let it run for about 20min before pulling the battery, and the folder was 1.5GB in size.

I'm not going to back up my extSD. I'll just pop it out, and put a small one in that only has the files I need. That way, my 200GB extSD will stay safe and not accidentally get wiped or corrupted during the flash. (This has happened)
[LG V20 Guides, News, & Discussion] nickthaskater:
Ah, I misunderstood, sorry. I back up via TWRP to either my SD card or I use my OTG adapter to back up directly to my external HDD or even a USB drive.

My full backups probably take around 30 minutes.

As for progress, TWRP should give you a progress bar and a percentage of completion (mine does). Make sure your TWRP is up to date (I'm on 3.1.1).
[LG V20 Guides, News, & Discussion] DrPhant0m:
I might have to try upgrading TWRP again. I had the latest version on, but there was an issue in it that caused my ramdisk to get corrupted, and I couldn't flash magisk or superSU. Where did you get your TWRP download? The only thread I can find with it is the same one that corrupted my ramdisk. Maybe it was a fluke... but another dev told me that he tested it and found the problem, but the TWRP dev never fixed it. It's in the thread around May and June if you want to check it out. Around that time, the dev had said he considered fixing it when he added OTG support, so it sounds like he may have fixed it, if you use OTG to backup to an external hdd. I went back to the original because my son was born in mid-June and I wanted to make sure my phone was stable in case of emergency.

Wait... do you have a USB-C OTG adapter? Where did you get it? I'll have to look for one of those again. I couldn't find any when I got the V20.

Thanks

lol... search for my username (DrPhant0m) in the TWRP-3-1-0-0 thread, and you can see my posts/issues. The dev almost admitted that there could be an issue... but later denied it and told me to write my own recovery. haha... yeah, right.

I ordered a 2-pack of USB-C OTG cables made by AUKEY via Amazon USA. $10 for both. I also grabbed a 128GB dual drive with USB-C while I was at it. Thanks for sparking me to check into it again.
[LG V20 Guides, News, & Discussion] DrPhant0m:
UPDATE: I clean-flashed 10n on my Verizon-connected US996, and it went well. I didn't lose my internal SD data, nor did I have to restore from my TWRP backup (though I'm glad I took the proper precautions).

As for Advanced (HD) Calling...

I do not have the "HD" icon by all of my contacts anymore like I did before... and "Advanced Calling" (turn on/off HD Voice) is greyed-out and selected to "OFF" Is it well and truly not on there anymore? Why would it have been removed? I think this was mentioned earlier in this thread... I'll have to look.

Also... (I'll have to test this more)

It seemed that I couldn't use mobile data while on a phone call last night

. As I waited for my Wal*Mart grocery pickup to be brought out... I couldn't send hangouts messages or browse in Chrome while on a phone call. As soon as I hung up, the messages resumed (send/receive) and the pages loaded. This is a concern to me. Has anyone seen similar issues? As I said... I'll have to test this out more, but I actually don't make that many calls during times that I can actually try to use my phone and test mobile data. I'll have to call the DMV or something so I can sit on hold for a while to test it out...:laugh:

---------- Post added at 11:42 AM ---------- Previous post was at 11:40 AM ----------

I installed TWRP 3.2.1 after the 10n update from HERE. I didn't want to introduce any more variables than necessary when flashing a new OS... so I haven't done much in recovery yet. Try at your own risk.
[LG V20 Guides, News, & Discussion] solo2racer:
I don't know for sure, but my guess is that since the update was pushed out for the US996 non-carrier phone, it didn't go through the necessary testing on Verizon to be certified for HD Voice.

This is working as intended. Legacy voice calls on Verizon are made using 3G CDMA which doesn't support simultaneous voice & data access. Enabling HD Voice (aka VoLTE) uses the LTE network for both voice and data and they can work simultaneously. Unless HD Voice gets reenabled by Verizon, you will not be able to do both at the same time on 10n.

I'm hesitant to install a non-official version of TWRP on my phone, considering it has root access while running. I've made an exception for the version posted on XDA, but I'm hesitant to trust a binary that I downloaded from reddit. YMMV.
[LG V20 Guides, News, & Discussion] baldybill:
What are the updates included in this?
[LG V20 Guides, News, & Discussion] DrPhant0m:
Ugh. This sucks so bad. I just had to make a call to an insurance company and refer to an email I got from them... Couldn't do it.

Is it feasible to think that there's a way to enable it in the ROM, or with a flashable zip that would include the HD Voice parts from a previous release?

Is 10l VoLTE-enabled? If so, I'll downgrade to 10l... but 10n obviously has the "latest" security patch level. I'm not sure what else it has... but I'm not really seeing much that's all that different from 10h.

Thanks for the info, albeit it wasn't the news I wanted to hear. haha
[LG V20 Guides, News, & Discussion] DrPhant0m:
The 10L and 10K links in the OP seem to be broken
[LG V20 Guides, News, & Discussion] DrPhant0m:
Were you ever able to re-enable HD Calling? Also, the service menu code I use is *#546368#*996# and I'm able to get in as soon as I touch the final pound sign. Have you tried that? Could there be more than 1 hidden menu with other options?

I found the same two items, and had the same results. I'm trying to re-enable advanced calling in 10n, specifically VoLTE so that I can use data while on a voice call. Even though the "switchactivity" item was already enabled, my data still cut out as soon as I enter a phone call, and resumes as soon as I end it.

I also used JRummy's build.prop editor, and found the following two items, which were already true:

persist.lg.data.hvolte_vzw = true
persist.radio.volte.dan_support = true

I even used the My Verizon app to check the status on my line and interestingly... I have a "Video Calling Block" enabled on my line... which I can't disable. It just says my request can't be processed... but other options can be toggled (such as visual voice mail and VCast content)
[LG V20 Guides, News, & Discussion] solo2racer:
I have not been able to get HD Calling working since I installed 10n.

That service code is a different hidden menu than the one that you get *#*#4636#*#*.

This is why I said above that it's a likely a Verizon issue. All the settings on the phone under our control are set to support HD Calling, but the network isn't accepting it. Same problem as WiFi calling - I can enable it on the phone, but Verizon's network doesn't accept it on a non-branded phone so it doesn't work. When I uses to be able to bring up the 4636 service menu, there was an option to view the network features that are currently enabled. VoLTE showed as enabled, but WiFi calling was disabled. Since I can't bring up the menu now, I can't check, but I expect both are network disabled.
[LG V20 Guides, News, & Discussion] DrPhant0m:
[MENTION=4584245]solo2racer[/MENTION]...

I fixed it!

I doubt any of my previous efforts helped... But all I had to do was log into my Verizon account and turn off advanced calling for my line. I got a text from Verizon shortly after with a bunch of garbled characters.

I then waited about an hour, and re-enabled advanced calling on my line. Soon after I got another odd text from Verizon, the advanced calling menu in settings was no longer grayed-out, and it was set to ON!

I promptly made a voice call and started a speedtest. To my delight... The call connected and I still had the 4G logo in my status bar. The speed test completed as well. I was on VoLTE.

Please try the same and report back how it works for any of you that were having the same problem.

I haven't restarted yet... But I'm hoping that the setting is etched into this ROM install now and it will persist across boots.

Good luck!
[LG V20 Guides, News, & Discussion] solo2racer:
Coincidentally, I did some more Google searching earlier today and found the same suggestion. I tried it and it re-enabled the HD Calling option.

Strangely, the phone book still doesn't show the HD symbol for calling. I was going to do more testing before posting the suggestion, to see if it's really using VoLTE for calls. As you suggested, I was able to use simultaneous voice & data with it enabled, so it appears to be working correctly.

I turned the Advanced Calling feature off and on within just a couple minutes on the Verizon web site, there's no need to wait a long time.

[LG V20 Guides, News, & Discussion] elcanela:
If it says unknown model, it means it's recognizing the fact that there"s a device connected, and not bricked. That is correct, right? It doesnt say waiting for device, does it? . I suggest trying uppercut with LGUP. It helps with the .dll issues by bypassing the dll check. Just make sure you have the correct KDZ
