[rooted] H815 can't OTA update because of TWRP

Hi folks,
Almost everything is in the subject.
I'm absolutely convinced I'm not the first one to experience this, but I can't find any thread about it ...
My LG G4 H815 is rooted with TWRP installed. I've got the OTA notification for a V20d-JAN-15-2016 (actually running V10d-EUR-XX).
I can download and initiate the update, but my phone reboots in TWRP (instead of bootloader I suppose ?) and the update hangs here.
Is there a way to go through this ?
Thx
Diego

Once you put a custom recovery on your device or make any other system changes it blocks the ota from being installed and even if the ota went through (which it can't) you'll lose root , you should already know this information ...

Oh and p.s when you rooted your phone you should of gone in the settings and unticked for the system to check for updates automatically , if you didn't do that then do it now ...

You're right I should, but I never faced this limitation on my prior phones (nexus/samsung/moto), so I didn't !
But I'm still confident there is a solution !

If you have twrp, you should flash the v20d flash files, offered in the general section the g4 forum

You can use LG Bridge app to update your phone as long you use original LG rom.
No need to create account even, unless you want to use backup feature.
EDIT: You will need to root the phone again after the update is finished (bootloader remains unlocked).

Confirming above for H815 EU rooted and bootloader unlocked, coming from v20D.
The notifications to update were really annoying me so i bit the bullet...
Update via LG bridge - all apps and data retained, but lost root and TWRP.
Followed this guide (again!) to install TWRP and gain root (scroll down til you find the relevant bit), hooray.
http://forum.xda-developers.com/tmobile-g4/development/stock-h811-20i-images-kdz-flashable-t3308227
Make sure to use newest SuperSU (v2,76 currently)
Now just got to remember how i disabled the annoying boot sound!

Guys when will people learn if your rooted or twrp you should never attempt to ota best case scenario it wont update worst case other than bricks is hard bricks and or even on unlockable bootloader is complete loss of root. some device manifactueres even went as far as blocking boooader unlock. And unablity to downgrade.
Never ota wait for modified updates. This has always been one of the first rules of rooting next to backups backups backups!!!

can you specify what are the relevant bits? Because one of the steps in rooting says "fastboot oem unlock (this wipes ALL data!!)", and I really don't want to do that again :angel:

Reinstall twrp (instructions use old twrp, I used newer 3.0.2 version)
fastboot boot twrp-2.8.7.1-h811.img
6. For perm TWRP: In TWRP hit Install > Images... (bottom right corner) > select TWRP.img on ext sdcard > select "recovery" > swipe.

Then flash supersu, done!

hey, it seems it worked like a charm, no data lost, very fast, so I am VERY pleased. Thanks a lot, really!

I snooped the LG Bridge link for the USS998, changed my user agent to Google Spider and was able to download it to my PC -- while LG Bridge was still downloading the update for my phone.
However, that link does not work automatically like yours does. When I pasted it back into any browser it now gives me dead connection. I DO have the file and I uploaded it to mirror. Just curious why YOUR LG Bridge link works and mine only worked one time?
Here's the entire link:
Code:
http://pkg03.lime.gdms.lge.com/dn/downloader.dev?fileKey=FWD5829D728DAEYA736DNZ7/US99810c_03_1216.kdz&e=1516284041&h=47a8578c8219b2cded92e25464de8098

But clicking on either does not start a download.
Very strange.
Here's my mirror, so I have the US998 file...

Any ideas why your LG Bridge link (for H930) works and mine (for US998) doesn't?

Change pkg3 to pkg2 on the beginning of the link Found this trick on YouTube. When you do that it shouldn't even need useragent changing.

I was stuck on 10f but with December security patch. Flashed 10v and it had November one... Then thanks to kind reddit user I got link to this 11m which has January patch. Now I don't have to worry about this Spectre/Meltdown vulnerability.

I have just downloaded the H930 update on my phone v11m.
I am rooted and have recovery installed. how can I install the update? When the phone tries to restart it just boots into recovery without installing the update.
Is there a way I CAN update to this?

You cant install this update inside TWRP.
Only with LG Tools.

Follow this guide and you will be able to flash it to your H930. Root will be lost and you're gonna have to root again.

Flash stock software update through TWRP?

First of all this phone belongs to my dad. This means I haven't used it and I'm not familiar with many things about it.
The phone is running a stock ROM. It is not rooted, but it does have TWRP.
A software update prompt popped up trying to install "v20p-apr-03-2018" (why is an update for the G4 called v20 lol).
Telling it NOT to download it and NOT check for updates ever doesn't work. The update prompt comes back in 2 days tops. So **** you LG.
Since it's not rooted the easiest option seems to be to flash the update, however it just launches TWRP and does nothing. I found no way to actually download the update and keep it on the device so that I can manually tell TWRP to flash it.
So: Is there a way to download said update and flash it through TWRP? Or should I root it and delete the stupid update tool? I really don't want to flash a stock recovery.

Freeze or uninstall Software Update (LG proprietary, i.e., closed source, app) - may require root. That should stop the annoying requests. If you are able to upgrade you will lose TWRP and will have to re-flash TWRP again. You may want to consider that you do not have the latest Google security patches by not doing the update, putting your Dad's phone more at risk.

It's not like LG updates security patches that often so it's not that big of a deal if I can't update it.
It's also fine if I lose TWRP during the process, I just want to avoid flashing stock recovery just for the sake of updating it.
And I still can't download the update and keep it. I don't know where it puts the update after downloading it. I couldn't find it in TWRP.

It helps if you include your phone model when looking for specific firmware updates.
If you're Dad's phone is an H815, there are some v20p downloads available here: https://lg-firmwares.com/lg-h815-firmwares/firmwares/
In order to flash in TWRP without losing TWRP, you would have to remove the stock recovery and create a flashable zip ...
Easiest is to simply freeze or remove the lg Software Update app as I indicated - the annoying update notification should then disappear ...
Note: XDA courtesy is to hit the Thanks button (bottom right of post), when members are trying to help and solve your issues. As a Senior Member you know this.

This update does not contain any security fixes it's just for the new European data protection law..
First thing you should try is:
Upgrade TWRP.
Do a full TWRP backup!
Test android update again.
Second thing:
Have you tried the LG bridge windows software to update?
If so and it fails there too you can find the update when you try to Flash it within the LG folder of your Windows PC afterwards use this KDZ file and lgup to flash it.
There is a chance that when using the internal updater that you can find the update file when in TWRP in /cache in a folder fota but it will likely be in a LG specific format so may don't help you much.
Third thing :
Disable the LG updater within TWRP (search for a howto)

Stock Frankenstein Post-July Oreo->TWRP (Also, fixing no sound issue)

I'd like to update to a more recent security version....
I bought my V30+ online from BREED (an Amazon reseller). The hardware model number, according to the phone, is LG-US998. According to LG (on their website), it's an LG V30+T (Sprint). I'm on AT&T. The phone works on AT&T just fine.
I called Sprint, and they have the IMEI in their system, no lost or stolen, but they won't unlock it.
I'm stuck on US99820e (September 1), and LG Bridge says "Cannot check the software version. Try again." (MTP, backup, everything else works). I've tried it on my Macbook, and on a Windows 10 machine. Neither option works, and both give the same error.
I called LG, and they couldn't find any way to connect to LG Bridge.
No OTA update available.
What are my options for updating here? The phone is not currently unlocked (checked this via ADB). Do I need to unlock to use LGUP and flash a later kdz file, or can I just flash it on top of what I have? I'm aware I'd need to unlock the bootloader, etc, in order to use TWRP. Or should I just wait?

Bought US998, found out it's former LS998 -- no updates

Many of the US998 found on eBay are actually former North America variants from other carriers -- most often from carrier locked Sprint LS998 and AT&T H931. Flashing to US998 firmware SIM card unlocks these phones and gives them fastboot flash commands. Here on XDA, we do this all the time, either for carrier unlock/updates and/or part of the WTF bootloader unlock and root process.
This North American variant conversion is called "Frankenstein" conversion. Your former LS998 is fully US998 and now has these bands:
http://www.lg.com/us/cell-phones/lg-US998-Unlocked-v30
US998
CDMA: 800 MHz CDMA
2G GSM: 850/900/1800/1900 MHz
3G UMTS (HSPA):850/900/1900/2100 MHz
4G LTE Bands: 1/2/3/4/5/7/12(17)/13/20/25/66
Many eBay dealers use the Frankenstein conversion because it's easier to sell carrier unlocked US998 phones than Sprint locked LS998 phones. Also, for AT&T H931 and Sprint LS988, those carriers only give updates to current customers via OTA; they do not publicly release KDZ. So, for non-customers with those phones, converting to US998 gives easy access to KDZ updates -- like posted in this forum. I've bought LS998 V30+ phones myself and immediately converted them to US998 via Frankenstein to use on AT&T.
UPDATE THE PHONE:
Just update via LGUP from the US998 KDZ thread. Takes 5 minutes and you can be on latest US998 KDZ.
Download the most recent KDZ from the US998 KDZ thread and use "Upgrade" option in LGUP. Use attached LGUP in post #1 of that thread. Installation instructions for LGUP are also in post #1 of that thread.
No need to unlock bootloader and install TWRP just for updating stock firmware. However, you can do that in the future if you want to add additional functionality. For instance, to fully enable DTS 3D stereo on the US998 you need root. To have the call recording feature, you need root. To enable all the LG lock screen weather animations you need root. To enable dual speaker mode, you need root. But just to update stock firmware you do not need root.

I almost always have a heart attack and think my old Windows computer is going to pick the upgrade moment to crap out on me and it never does. I imagine myself out $400 for a nice new phone, and crying about it to my wife, who would certainly be rolling her eyes, and wondering why I don't just stick with iPhone because it's easier.
None of that happened. Except for me inadvertently choosing "refurb" mode instead of upgrade mode, and thus wiping all my user data and having to get it from the cloud all over again, everything looks like it went swimmingly well and I'm on the latest update.
Thanks!
(Just to confirm... I DID hit the refurb button, right? Even in download mode, hitting upgrade wouldn't have cleared my data, correct? No big deal either way. I'm used to setting up my phone again and again, but I just wanted to confirm.)

Refurb is the default option in LGUP -- so you probably did not choose anything. If you have chosen upgrade, that would have kept your data. About a month ago I was updating my wife's phone while doing three other things at once... It quickly and completely wiped the entire phone because "refurbish" was chosen. ARghhhh. I spent the next three hours setting up her phone again. Normally I'm more careful.
Refurb can be useful in some situations, but in your instance (and my recent one) "upgrade" is what was wanted. This screenshot below is from months ago, but still shows the two "refurbish" and "upgrade" options.

Still you now have your US998 updated, and you know what to do in the future.

Which means you after refurb-upgrading to US998 20G last night and setting up your phone again... Then this morning you temporarily downgraded back to US998 20a or 20b, unlocked the bootloader using the WTF instructions, installed TWRP and Magisk. And by now you've probably flashed the @JohnFawkes TWRP-flashable US998 20G zip file to upgrade back to current firmware, while having additional functionality with root -- and actually being the admin of your phone.
(The only thing you didn't have to do was the Frankenstein from Sprint LS998 firmware to US998 in the first place. The dealer did that for you.)
Still, I'm actually impressed you did all that in so little time from knowing basically nothing about this phone last night. Kudos. I like success stories like that.

I'm a software dev myself (NodeJS/AngularJS), so computers and stuff aren't foreign to me. I'm just cautious by nature when it comes to this stuff.
Full sequence (for posterity, or anyone else looking to do the same)
Last night: (using patched LGUP) Set to download mode and upgrade to 20G.
(This morning): Download Nougat kdz, Oreo Pre-July kdz, new_unlock.bin, encryption de-verifier, rctd disabler, Magisk 18, TWRP, TWRP-enabled 20g zip.
Set to download and downgrade to Nougat (refurb mode) (per your instructions)
Factory reset the phone (to be safe)
Set to download and upgrade to Oreo "a" (upgrade mode).
Partial phone setup - enable USB debugging and Unlocking bootloader.
Connect phone to Mac (More comfortable there)
adb reboot bootloader
fastboot flash unlock new_unlock.bin
fastboot reboot
(Setup steps to reenable USB debugging)
adb reboot bootloader
fastboot getvar unlocked (verified unlocked)
fastboot flash recovery TWRP.img.
fastboot boot TWRP.img.
Swipe to allow modifications.
Backed up the system to SD Card.
Wipe Data -> Factory Reset.
Wipe Data - Format Data (this failed initially)
Reboot to recovery.
Redo step 18, this time with success.
Install magisk.
Install encryption disabler.
Install root check disabler.
Reboot (I'm honestly not sure if the last three steps are necessary)
Reboot to bootloader (force phone to "factory reset" menu, and click yes through it... that got me to TWRP.)
Flash 20g.zip.
Flash Magisk.
Reboot.
Setup for real.
Download AnxiousOS Magisk module and install (within phone).
Currently waiting for the phone to restore apps, etc, then I'll reboot.

Great.
The only thing you personally didn't have to do -- since you were already on US998 Oreo -- was downgrade back to Nougat. You just needed to downgrade from US998 20G back to pre-July US998 Oreo (20a or 20b).
For people converting from LS998 to US998, they HAVE to do the US998 Nougat first before going to US998 Oreo -- they can't just jump from LS998 firmware to US998 Pre-July Oreo; LG put some check in there that prevents that. So, going to US998 Nougat bypasses that, then they can upgrade to US998 Pre-July Oreo. Still, those extra steps I'm sure gave you more practice with LGUP.
But your checklist is perfect for those having to convert from LS998 to US998 and then going through the bootloader unlock/TWRP/root process.

Try flashing just 20G TWRP flashable zip and reflash Magisk. Set up, see if you have audio.
It not, then flash 20F TWRP flashable zip and reflash Magisk. Set up see if you have audio.
Hold off on Anxious module until you verify audio.

Hmmm....
I noticed that the link for the 20G TWRP is actually for the H930, could that be the issue? I have a US998.... (previously LS998)
https://forum.xda-developers.com/lg-v30/development/us998-lg-v30-us998-us99820a040330-kdz-t3786337

I'm getting some errors in the logs.... something about denied (find) vendor.lge.hardware.configstore.... That sounds iffy.
Also, audio_hw_primary start_output_stream: pcm_prepare returned -1.
Here's the iffiest:

No, it's not for h930. That's an issue with the hosting site which categorizes all V30 as H930, due to the first developer who registered his H930 V30.

Reinstalled 20G, no-go.
Downgraded to 20F, worked fine.
Upgraded back to 20G, worked fine.
Looks like newcomers may have some issues, but those who went through 20F will be fine.
I have the logs for @JohnFawkes if he wants them.

This is after reflashing just 20G zip and Magisk?
Never mind, I see answer above.

You can now flash the Anxious Magisk module if you wish. Of course, make TWRP backup...

There isn't anything I can do about the no sound thing. Since you bought a phone that was already converted it is most likely a refurb. It seems like other users who had this issue (its mentioned in the us998 thread) were coming from aosp and had no sound. It's very likely your device was on aosp at one time. The flashable zip is just the kdz converted into a flashable zip. If its not giving sound its nothing I can fix. Its on lg unfortunately.

After installing Magisk and AnxiousV30, it all seems to work, with the sole exception of the dual-speaker mod (I'm not sure what to expect here... I try playing music through the speaker, and I'm kinda expecting it to come through the earpiece and the speaker at the same time). In any case, all seems well.

Yeah, with dual speaker it does come through the earpiece also, but can't be as loud as the bottom speaker. Now when watching videos for instance, helps to have some audio directed towards your face.

Yeah, but he flashed full KDZ in refurbished mode in LGUP at least twice before even unlocking his bootloader.
Issue is fixed now by flashing 20F, then 20G. Strange...
Maybe the issue stemmed from trying to flash the Anxious Magisk module before setting up the phone? It changes some stuff with audio. Maybe the phone was confused.

The correct way to update an AT&T model

So I've just recovered my phone from my 1st attempt at updating to Pie on my unlocked AT&T v35.
But I'm left wondering if the process for updating from Oreo to Pie is somehow different than when I successfully updated from Marshmallow to Oreo.
The process I thought was:
1. Put phone in download mode
2. Connect phone to pc
3. Run the Modified version of LGUP
4. Select your ULM KDZ choice (any of the three will do)
5. Select Upgrade
6. Flash phone
Are any of these steps incorrect and should step 5 be Refurbish instead of Upgrade?

I used upgrade, when going from ULM 8.0 to ULM 9.0. I would assume you would use refurbish if going from stock to another firmware. Of course assumptions aren't really reliable.

I've been trying to figure out if I should do UPGRADE or REFURBISH as well.
I found this: https://forum.xda-developers.com/lg-v30/how-to/guide-how-to-upgrade-downgrade-restore-t3738917
Says REFURBISH wipes user data, UPGRADE does not. If moving from one image say from AT&T, to the Unlocked firmware I'd assume you want REFURBISH.

So since I used refurbish to go to the ulm software from 7 to 8, do I still need to refurbish going to any of the ulm pie variants?

That's what threw me for a loop on my first attempt. Since I'd successfully upgrade from the AT&T 7.0 firmware to I believe the Amazon 8.0 ULM firmware without issues, I thought the process would be the same going to 9.0. But I ran the upgrade through LGUP which was the modified version, and it crashed at 74% and sent me down a wonderful rabbits hole of brickage.

I don't understand how were you on Marshmallow before flashing to Oreo. I'm pretty sure the the V35 launched on Oreo 8.0. But I'm also looking for a way to get from Oreo to Pie on ULM kdz.
I went from AWM12k to ULM10i choosing REFURB and all went well (I followed xatokk's post on the lgV35 subreddit).
When I try to get from ULM10i to ULM20d (Pie .kdz) I guess I only have to drag ULM20d kdz in LGUP window?
I just want to make sure that's not how you bricked your phone before I try REFURB from ULM10i to ULM20d
Any advice would help, I'm a noob at this.

FWIW, partition DL worked fine going first from AT&T firmware to Oreo ULM and then again to Pie. Sadly I had to set up the phone again.

Sorry, Brainfart, I was completely out to lunch on that. I wanted to flash the latest available security update, but since I'm in Canada I could never get that from AT&T so I had to find a way to flash it and that led me to XDA and the whole LGUP process. So you were correct on that, and I did flash the Amazon 8.0 KDZ I believe without issue.
My brick happened when using the Amazon pie KDZ and using the same Upgrade process in LGUP. The update got to 74% and then crashed. I then tried to run the refurbish option but that crashed as well so by that time, my phone was beyond my knowledge of how to fix it

Partition DL was not available in the process list of the modded version of LGUP I used. Which one did you use? I think I found the right one.
Now, selecting PARTITION DL, do I need to select all like mentioned in the Frankenstein Phone thread for the V30?

This phone launched with Oreo and had nothing prior. He's mistaken, confusing some other model.

That's what I did.
The error you experience may be due to a usb cable. a particular usb port on your computer, other software on your computer, and maybe bios settings. The v30 WTF and Frankenphone forums would be good places for background and solutions.
Fingers crossed for a successful flash.

Here's what I did if you don't already found a way. I also faced an error trying to flash to Pie ULM.kdz.
I don't know why but LGUP for developer patched from 9to5lg.com didn't work for me. I tried PARTITION DL it crashed at 91% and I also had to reboot my PC. I kept the phone plugged and reinstalled LGUP.
My V35 was on AWM12k when I got it. I followed xatokk's post on the lgV35 subreddit to get it to to ULM10i choosing REFURB.
I kept the same .dll I extracted from to ULM10i and I did a REFURB to ULM20d .kdz just dragging it to LGUP.
I hope this can help you.

To update my earlier reply on this topic. Somehow flashing REFURBISH from AT&T stock Oreo to ULM(Unlocked) Pie it failed and bricked my phone. As mentioned in another thread regarding unlocking the bootloader and root, I had to call on @motogvasyag to not only unbrick my phone remotely but he also unlocked the bootloader and rooted it. If anyone has any issues with bricking you might want to contact him. He's fast and does amazing work. I only mention this because I am very appreciative of him and his work. I'm not sure why my flashing failed at around 70 something percent but I'm glad to have my phone working again along with the update to pie and root.

@motogvasyag unbricked my AT&T V35 that was stuck in fastboot from a failed flash. Took care of it right away. Phone is now factory LG on Google Fi, Pie, wifi calling and all three carriers. Highly recommended!
