I have this rom mostrly working except I cant get tyhe Google Play services to update. It will give me a chouice of deactivating or "update" but uipodate ever getrs andqwher and cyycles abck toi tghso3 two chouces. Chazzmatt suggested going to the APK Mirror site but it offers some 32 variants and I diont know whether to try the first one offered or to try to figure out which of the 32 others to try.

I also opened the zip and flashed the modem.img to the modem partition and this ate the mobile network and mobile data. Opening the zip of US99820h_00_0318 and flashing that modem.img brought everything back except of course the play services and the lesser bands in the H931 modem.

Anyone have any ideas of how to resolve this? in bad shape without the play services...
[LG V30 Guides, News, & Discussion] mrsubway:
I've had no such issue with this ROM. My only suggestion would be to backup everything, wipe data, cache, dalvik and system, flash the rom, flash Magisk and start over. I'm curious. Is your provider AT&T? If not, there's really not a reason to use this ROM.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, he has AT&T. Originally he had a native US998 but AT&T wouldn't provision it (or whatever they call it) for WiFi Calling, etc.

So then he bought AT&T H931 from AT&T. (They warned him if he didn't, an eBay overstock H931 would not work for his purposes, as they kept a list and checked it twice -- of H931 IMEI they actually sold to customers.)

He's also prepping the US998 for return.
[LG V30 Guides, News, & Discussion] Bob Simons:
now my phone is saying it will install an AT&T update in 10 seconds

as I struggle to find a way to install the update to google play services, even though automatic updates is turned off under developer options, it has been bringing up a message asking if I want to install this update and I've been saying no. Now it says installing in 10 seconds with no abort/refuse option. I've turned the phone off afraid of what it'd do. Now my understanding was that a rooted phone wouldn’t update but then I guess that the wonder of systemless root is that this isn’t true any more . Am, I correct or do I not have to worry?

How can I stop this update? can it even be done or am I screwed? is there a way to find the update in TWRP and remove the file?

Can anyone tell me if I have to wipe this and start over? will this update install screw things up? Can I get the google play update to install? I was trying to install the best bet from apk mirror only top ruin into this speeding train.

What do I do?
[LG V30 Guides, News, & Discussion] Bob Simons:
if possible, it gets weirder

so now the update tries to install itself and reboot and drops into TWRP where nothing useful happens and so this is its future unless someone can tell me how to stop this update from starting in ten seconds.

does anyone know where it lives on the drive so I can delete the file using TWRP file manager?

I'm afraid I have to wipe the phone and start over (again) because I'm dead in the water twice over (google play servivces, update that cant complete or be stopped) now. That'd mean several more wasted hours.

Any ideas?
[LG V30 Guides, News, & Discussion] AsItLies:
Not sure this will help much, but in Dev op's for 'auto updates' it's referring to software updates for the os, not updates from google play applications.

Second, google play services, I don't think, can be stopped from updating? I think if you use google play, it *has* to update. Why do you say 'you're screwed' if it updates?

Sorry haven't been following this thread, but don't understand why a play service update is causing panic? Heck it updates on a regular basis, almost daily it seems.

Cheers
[LG V30 Guides, News, & Discussion] ChazzMatt:
I think you're misunderstanding. He wants to stop the AT&T firmware update notices and attempts, while at the same time he wants Google Play services to successfully update.

Two different "update" topics being discussed.

He needs to freeze the firmware updater files with Titanium Backup. And delete the cache wherever the OTA keeps trying to launch from?

I have no idea why he's having Google Play problems, but he says he is.

But yeah, if anyone can help him, please do so. I've not installed this ROM, I just pointed him to it since he's an AT&T customer and wants the full AT&T experience. I know no one else is having these problems, but if you can tell him how to install correctly, maybe flash the H931 modem correctly, and stop the OTA update attempts?

_______

[MENTION=701335]Bob Simons[/MENTION] , the instructions say this:

1.back up any internal storage files first

2.Flash zip (could Flash Magisk Root After)

3.Finish Android Setup (Install Magisk Manager)

4.Restart Phone (To Access Magisk Root)

5.disable automatic system updates

in developer options

6.to hide system update notification

Use Package disabler pro for LG App to select

system update app to disable

7.disable Mobile Services Manager

to prevent auto install of at&t & random apps

You've done #5, but what about #6 and #7? I'm not a big fan of Package Disablers as people tend to go crazy with them, but Titanium Backup can do the same thing and safer. FREEZE what you don't want to run. If it turns out to be something critical, you can UNfreeze it.

Have you tried FREEZING the system update app and the Mobile Services Manager in Titanium Backup?

[LG V30 Guides, News, & Discussion] ChazzMatt:
I have 7 category boxes on my TWRP (the stable 3.2.3.7-default TWRP from WTF thread), and I do NOT back up System Image. I back up the other 6 categories. I've restored backup images several times, using those 6 categories. You don't need anything else. You also don't need any other version of TWRP than what is in WTF instructions.

Also consider getting a bigger microSD card? I have 256GB microSD card on on my V30+ and my wife's V30 -- but 400GB microSD card has now dropped to $57. So, not only is that relatively cheap but it means the 256GB will be even less expensive....
[LG V30 Guides, News, & Discussion] AsItLies:
okay so the picture is a little clearer. Restoring from a backup or reflashing was probably the best option dealing with the 'looping' update problem.

Once restored / reflashed, first and foremost is to avoid it happening again. Turn off wi-fi and mobile data, and be sure no app has no permission to start mobile data and download in the background (i think that can be found in settings / networks/ advanced settings ... somewhere in there I know I've seen it.

The next thing would be to find the name of the service so it can be frozen. I use adb and package commands to get all the packages. Then, if you have linux (which has grep) it's easy to search all the package names and determine which one is responsible for the updates. It would obviously be a system package. Yeah, it is easy to disable it in tibu, but only if you already know the name.

you *could* try searching the net, with the right keywords you might get a hit. But adb package commands are pretty easy to get all packages. This page shows the various commands (including list system packages); http://adbshell.com/commands/adb-shell-pm-list-packages

I don't have my att device any longer, and only flashed this rom once, and used briefly. So can't help with the other issues.

Cheers
[LG V30 Guides, News, & Discussion] sguerra923:
Any word on an updated ROM? Looking to reflash because my H931 ROM is getting a little wonkey.. Might have a bug I got or something. Just seeing if David has something cooking in the kitchen. Or does anyone have an app they recommend to check? Thanks in advance!

[MENTION=701335]Bob Simons[/MENTION] So I have the same issue with the update loop. Not quite sure how it came about but what I do to stop the loop is to quickly go into

Settings

Apps and Notifications

App Info

Click the menu button in the top right

Select Show System

Scroll to the two Software Update apps

Force stop both

This will stop the loop from happening until the next reboot. I haven't had much time to investigate how to stop this permanently. Hope this helps! :svetius:

Crazy twrp flash, brick, no fastboot, brick, then success!!!!!!!!

Had H931 converted to US998. Flashed this rom with newest twrp and phone constantly boot looped. Tried multiple things to fix this with no success. Loaded up LGUP and flashed newest US998 kdz. Lost recovery and fastboot. Phone just loop booted for a quick second and showed the android guy on his back. Once again I went into download mode but this time I flashed US99820b_03_0524.kdz. Again loop boot but this time I lost download mode and recovery but I gained fastboot mode.

Using the twrp img I temporarily booted into twrp and flashed this rom. After flash I performed a master reset so I know some kind of recovery is there now. Phone booted, I put in my sim card and went through the setup process. Phone has been working great with no random boots or anything out of the ordinary except when it boots I now get the bootloader unlocked warning.

Sorry this is so long but I told you this to ask this question. What do I have now? Is it a US998 or H931? Software states H93120h. I no longer have twrp or root. Without locking the bootloader did I restore this back to factory?

Also after bootloader warning I do get the AT&T logo. If AT&T's newest update comes in will it flash it or will it boot loop again?
[LG V30 Guides, News, & Discussion] ChazzMatt:
1) Are you an AT&T customer?

2) What "newest" TWRP did you use? Only use the 3.2.3.7 stable TWRP from the WTF thread.

You don't need anything else, especially BETA EXPERIMENTAL 3.3 TWRP If you used that, that's e eason for your problems flashing this stock-based Oreo ROM.

3) "Using the twrp img I temporarily booted into twrp and flashed this rom."

But you didn't reinstall TWRP...

You need to reinstall TWRP.

4) Yes, the whole point of this ROM is to flash back to AT&T firmware -- but keep TWRP and root. It's debloated, but you need to freeze or disable the system update files.

This ROM is ONLY for AT&T customers. Everyone else with H931 should stay on latest US998.

[LG V30 Guides, News, & Discussion] jmccarty1974:
1. Yes I am a AT&T customer

2. TWRP-3.2.3-7

3. No I did not reinstall twrp.

Why do I need to reinstall twrp? Unless I plan on updating this phone I don't need twrp anymore. I have AT&T next and I am planning on upgrading this phone in a month or so. (Guess I left that part out sorry). That was the main reason I was flashing back to stock as possible.

So if I was to boot into fastboot and run fastboot oem lock do you think it would work or fubar the phone? Again phone has been working great. I have checked for updates but it says it's up to date. AT&T software update page states newest version is H93120r.
[LG V30 Guides, News, & Discussion] anarchopunkbarbie:
Follow the Instructions and It Works

In Titanium Backup, freeze the FOTA and both Software Update packages. That will prevent your phone from trying to update Android or AT&T and leave your Google Play updates intact.
[LG V30 Guides, News, & Discussion] jmccarty1974:
I guess I should have been clearer in my post. I only use stable builds of twrp. If someone wants to be a guinea pig and use beta software I say "To each his own". I was using twrp 3.2.37 stable. The funny thing is I have been doing this for a long time and this is the first time anything like this has happened to me. All my Nexus devices 4,5,6, Samsung, Motorola, One Plus, etc I have never had any issues with. Long story short once this phone is gone I don't think I'll ever buy a carrier branded phone again.

At the end of the day I'll go back to US998 firmware and lock the bootloader and sell as you suggested. I was wanting to trade it back into AT&T so that my wife could upgrade her phone but I guess I'll buy her a new phone that is not locked down by a carrier such a my Xiaomi Pocophone I can rom all day long without any issues.

Thanks for all your help :D
[LG V30 Guides, News, & Discussion] Bob Simons:
I found that it was impossible to fix things because the update process would grab "focus" and turn the screen white and unresponsive within 10 seconds. Tibu takes far longer than that in that you have to start it up, press backup and wait for it to populate or hit search and try to freeze it. I never got close to being able to do this.

I wiped the phone and reinstalled the KDZ with LGUP and never had the two problems that I'd been unable to solve the last time(s). First, I found Google Play Services to be at the version I could never upgrade the last one to, version 17.x (don’t have the info in front of me now). This meant I didn’t have to try to get the update to install as it had happened automatically on its own. Second, the AT&T System update message never came up so I was able to freeze the services in Tibu. I found a service called something like system update service v8.0 which I considered a good guess as I was on Android v8.0. In short, everything worked exactly where it hadn’t worked the last time. My experience this time basically matched the norm for all the rest of you. The bad thing stopped happening. I stopped being special in that unwanted way.

After all that I’d gone through I should have just done this from the outset. Between the US998 and the H931 I probably did a total of 6 or 7 clean installs. Every time starting over was faster than trying to get updates or repairs to occur.

Also, as I said before, the H931 bought from an eBay reseller as in fact indistinguishable from a factory store sold unit as I expected, and ChazzMatt also expected but contrary to all reason, AT&T kept insisting it wasn’t going to work. I also resisted trying to avoid more possible disaster. I was expecting everything to go wrong as that had been my track record with this project for reasons I couldn’t understand. Ignoring AT&T and buying the H931 from the eBay reseller was when things started to go right. Slowly, though with a lot of errors at first.

I've been told never assume ignorance when stupidity will suffice. I looked it up and see there is a Wikipedia article on the similar saying. This was by far the second most trying technical problem I’ve ever had, second only to having AT&TG install the fiber at my house for their U-verse gigabit internet.

Have you ever heard frank Zappa’s statement?

Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that. I say there is more stupidity than hydrogen, and that is the basic building block of the universe.

I think I was the stupid one because I believed AT&T or at least considered the possibility that they were telling the truth.

Thanks again to everyone, especially ChazzMatt.
[LG V30 Guides, News, & Discussion] mrsubway:
If anyone wants to get their phone back to near stock to resell, you could probably flash this rom. You could theoretically get ota updates if you flashed the AT&T recovery. I do not know if that's available. OTAs don't work because after the download, the OTA tries to reboot to stock recovery. TWRP doesn't know how to handle it, and the assholes at AT&T never release KDZs. Why? Because they suck every nasty part of a donkey's anatomy.
[LG V30 Guides, News, & Discussion] super1395:
I tried flashing the stock recovery and got an error when it rebooted to recovery. Rebooted the phone and was greeted with "this phone is suspected of being rooted and cannot perform software updates" or something along those lines. Essentially any H931 who converted to US998 has no was to get back to true, out of the box, stock. So future flashers beware :) woulda been nice to have that be a little more apparent.
[LG V30 Guides, News, & Discussion] ChazzMatt:

You simply sell it as a US998 on eBay. That's what people want anyway, an unlocked phone that you can update.

Now I have 0 chance of sending my phone in if I need to, because there's no official images from ATT, and that's not mentioned in the guide anywhere... never woulda messed with this if I knew that returning to true stock wasnt an option.
[LG V30 Guides, News, & Discussion] ChazzMatt:
It's known that both Sprint and AT&T do not release public KDZ. This is why Frankenstein is popular and existed even before WTF. To convert H931 and LS998 to US998.

You can easily sell the phone on eBay as US998. Once you unlock the bootloader any warranty is void anyway, if they really want to check.

Guess that's the downside of assumptions. I didn't know that, and in normal cases the bootloader can be relocked. Anyways just a consideration for those like me.
[LG V30 Guides, News, & Discussion] br0adband:
As noted, once you unlock the bootloader poof, the warranty is done for already whether you do the conversion to US998 or not. But these days, as I've noted in other posts, LG doesn't really give a damn about such things because they're scared, they are literally afraid, that someone out there could get pissed and file another class action lawsuit so regardless of whether you unlock the bootloader or you convert a variant to the US998, make sure your device is legit registered for warranty service regardless of what you are planning to do or what you may have already done to it.

And by "legit registered" I mean go to LG's website, sign up for an account if you don't already have one, sign in if you do, register the IMEI of the given V30 you have and when it asks when and where you got it, pick a date in the past 2 months or so and a carrier location in your area or whatever and get 'er done. At this point they don't care if you're the original purchaser or not, they don't care if you've unlocked the bootloader or not, or anything else for that matter - they just accept the product, do the repair (most anything except replacing the display/glass if that's damaged or destroyed 'cause that's not covered by the standard warranty), and send it back, no muss, no fuss, case closed.

I've never had any issues with warranty service over the past 5 years or so regardless of the point of purchase. LG has been good to me in that respect and that's why I continue using their products. I've sent in over 40 devices from the G2, G3, G4 (7 of those, 6 with the bootloop defect, all of them repaired), G5, and several V10 and V20 devices too - every single one of them was repaired and sent back and none of them ever had issues again for the rest of the time that I owned them.

Just gotta be patient and stand your ground when making a warranty claim, really, they'll do it if you don't give up.

Anyway, off-topic now so... ;)

What kind of updates? This is a TWRP-flashable zip. You better never get OTA updates with TWRP custom recovery installed, or it will mess up your phone. If OTA updates are offered you should decline and freeze any update files.

Any updates to TWRP-flashable zip (ROM) will come if/when this Dev releases another TWRP flashable zip. He's not been active in a few months, whereas before he was very prolific.

His last post on all of XDA was in this thread:

April 19, 2019:

Hope he comes back!

AT&T is like Sprint -- they do not release any public KDZ and it's a pain to create TWRP-flashable zips.
