[US998][STOCK][PIE]LG V30 US998 US99830b_00_0902.KDZ

[TheDannemand]

Well it's the AT&T variant, which I got unlocked and then flashed to US99830b. So yeah its the H930. And thanks for the heads up! If I find it even a bit risky, I'll just say meh to Volte and make do with what I have.

That's not H930 (the European model) but H931 (AT&T model). They are very different. Even if you COULD convert your phone back to H931 (which you can't) it's not going to help you as H931 won't have carrier configs for Indian carriers.

Do you know anybody who has a H930DS?

In any case, study that thread I linked. Maybe H930DS owners shared information in there that you can use.

Ahh I did not know that, but now I do. Learn something new every day. And no, as far as I know, I'm the only LG user, let alone V30 user in a good radius. But yeah, I'll read the thread first thing in the morning. Man, this forum is the most helpful place in the world. Thanks a lot for your help, buddy!

Now I just have one last question before I stop bugging all you kind folk.. And this might be a really stupid one. When I was on us99820h Oreo, there was this app on my phone which optimized Storage and Memory. It was a real helpful app for clearing out cache and freeing RAM at the same time. It's not there on US99830 Pie. Can anyone tell me anything about this?

You can create a shortcut on your home screen using Shortcut Master Lite or if your launcher supports Activity shortcuts (such as Nova).

I would not expect more updates, but of course it's possible, seeing some recent carrier model updates.

US998 has VoLTE and VoWiFi built in, but no user interface to show it or control it, except for TMO. You have to use Hidden menu (*#546368#*998#) - Field test - IMS Settings to control it. And it's far from user friendly.

I wrote some guidance on it in ChazzMatt's VoLTE thread and a few other places. I'll find some links once I get to a computer.

In many cases VoLTE will just work if your carrier provisions it. But you won't see any icons to show it, unless you specifically enable VoLTE indicator in that hidden menu. Again it's described in those earlier posts of mine.

Edit: Check the post linked below and the discussion from that point on:

Would this work you have done be relevant to me and Sprint US?

I have no firsthand experience with V30 on Sprint, but I don't see why not, as the Sprint carrier config is built into US998. As long as the phone detects a Sprint SIM (or Sprint MVNO) it will try to load that config. Of course this assumes the Sprint (or the MVNO) provisions the phone and SIM for VoLTE/VoWiFi.

THANK YOU SO MUCH!! I don't see a way to make a shortcut, but that's fine by me. I'll do it the long way.

I had it all working on Stock 30a(JohnFawkes) OREO, so the phone and sim work if its properly set up....HOwever on Aix Stock based RoM its not working...

Understood.

You'll have to ask the Aix dev about that. It's a stock based ROM, and I assume it includes IMS.

As for it working on stock JohnFawkes 30a, I assume you mean the Sprint ROM -- which we'd expect to work on Sprint.

Since this is the US998 stock ROM thread, we should confine the discussion to that

Hi, I tried to flash the US998 Pie zip stock rom on top of the US998 Oreo 20h and got stuck on the boot logo. I'm able to get out of the bootloop and enter download mode but there's is no connection, "Firmware update, Now waiting for any connection..." I tried 2 LGUP versions, the patched one from the Pie thread and an older one, Ithink it's the same 1.14.3 but without the dual mode. The PC has the correct drivers installed.

Anyone has some suggestions ?

Thanks

HOW did you flash? TWRP? KDZ? Did you read the first post in this thread and the recovery info posted there?

[Frankyxda]

Hi, thanks for your reply. I've managed to restore it to the stock Pie H933 ROM. I didn't realize that I was still able to access TWRP with the "button dance" because I was using modified stock zip that don't overwrite it, so I simply reflashed the stock ROM in TWRP and later in LGUP for Pie and that was fine. I don't have root anymore but I don't need it right now.

Hi, I flashed the US99810d Nougat KDZ using Partition DL, however instead of selecting all the partitions I left recovery in hopes of retaining TWRP. I inadvertently did the button dance right before the phone booted, out of habit (I was used to flashing H933) and now whenever I try to boot normally or into download mode, the phone boots TWRP and I have no idea how to get out of it.

Basically download mode is gone, however I can boot into fastboot, but doesn't seem to recognize my device even though I have the necessary drivers installed. I tried flashing JohnFawkes' US99820e, to no avail.

Any help would be greatly appreciated.

What happens when you boot into download mode via TWRP Reboot?

What happens when you boot into download mode via TWRP Reboot?

nvm, I manually booted to download mode and flashed US99820a. Turns out I wasn't holding the vol up button long enough.

However, fastboot doesn't recognize my device anymore, although ADB can. I've tried with different cable and devices, disabling signature verification on win10 in order to install Google's USB drivers, nothing seems to work.

Try installing LG's USB drivers, not Google's. And maybe another Partition DL to Nougat then back up to Oreo. All partitions this time.

BTW good job getting download mode back

I've tried installing them both, no effect. I was actually missing a completely different set of drivers, which I found on a different thread. Fastboot works great after installing.

I'll put the drivers here if anyone else needs them:

HOW TO (temporarily) DOWNGRADE BACK TO OREO FOR BOOTLOADER UNLOCK
(or DOWNGRADE BECAUSE YOU DON'T LIKE PIE)

1) DOWNLOAD FIRMWARE AND DEV PATCHED LGUP

* Download Oreo KDZ you wish to install -- for bootloader unlock would be US998 20a or 20b.
(If you just don't like Pie, then choose the most recent Oreo KDZ in that thread, which is US998 20h at the top.)

* DOWNLOAD THIS DUAL VERSION OF DEV PATCHED LGUP, made by @tecknight:
https://androidfilehost.com/?fid=11410963190603845019
(Or use attached file from bottom of this post. Thanks to @tecknight! Please go here and click the THANK BUTTON!)

_________________

2) INSTALL DEV PATCHED LGUP

1. Extract LGUP_DualMode.zip to a folder on your PC.

2. Browse into the folder and launch LGUP_Store_Frame_Ver_1_14_3.msi.
Follow the prompts to complete the install.

3. In that folder, right click and select "Run as Administrator" on "SetDev.bat" to set LGUP to developer mode

4. Launch LGUP using the desktop shortcut.

Choose Process : PARTITION DL or REFURBISH

----------------------------
3) DOWNGRADING ANY LG V30/V30+/V30S TO EARLIER OREO KDZ FIRMWARE

1) Go into download mode (power off completely, then hold volume up button while plugging in USB cable)
2) open patched LGUP and flash OREO KDZ to DL PARTITION mode. In the pop up box "Select All". Use the attached patched LGUP in this post.
You can also use REFURBISH mode, if you wish.
3) Master Reset (post 101 of Frankenstein thread)
5) DONE.

It's fairly easy. Most people breeze right through this. But if you have any problems, go through this list:

• Make sure you in download mode BEFORE opening the patched LGUP file.
  This is at the top of the list as some people forget to do that. The remainder are in no particular order. If that doesn't work,
• Try different USB port,
• Try different USB cable,
• Try different computer.
• Reinstall LG mobile drivers on your PC.
• Reinstall dev patched LGUP again, making sure the files are placed where they need to go (LG Electronics folder, etc).
• Reboot the computer.

If you ask for help, that's the list of items we are going to give you anyway.

WARNING: In LGUP do NOT go messing with modes not mentioned in these instructions. Especially do NOT use Chip Erase.

Hello! Thank you for the post, I followed your instructions but when the phone reboots the phone won't turn on but the loop restarts. I remember before reading your article on how to fix this error, but now I can't find it. ask for your help. thank you very much. Sorry for using google translate so the words are not good

You are probably thinking of Master Reset, to stop the bootlooping. But if you are downgrading from Pie US998 to Oreo US998, there shouldn't be any bootlooping. HOWEVER, if you are crossflashing from another firmware like AT&T H931, Canada H933, Sprint LS998 to US998 Oreo KDA -- yes there will be bootlooping. For those you will need to follow the Frankenstein directions, where you downgrade to US998 Nougat. Run Master Reset to stop the bootlooping. THEN, you can update to early Oreo US999 for bootloader unlock.
