Update from Pie to LOS 17.1

Dear members, since yesterday I´m trying to update to LineagOS-17.1 Rom without success.

At the moment I have the H93031a_00_OPEN_EU_OP_1105.zip from seadersn installed

I started with the guide in post https://xdaforums.com/showpost.php?p=81770855&postcount=1885 and got into a bootloop.

Several other methods described here in the H930 forums also didn´t work.

Flashed the stock pie H93031a_00_OPEN_EU_OP_1105.zip and the the H930_22j_partitiondl_modem_00024.img from the Telegram Update Chanel and then wiped again and installed the LOS17.1, NikGapp-core-arm64 and Magisk 20.4.

I also tried the Kernel-Sepolicy-Patcher. Nothing worked.

TWRP 3.3.1

Am I missing something? a helping hint is very much appreciated.

p.s. I never installed through kdz, always with flashable zip files from seadersn.

Which Los are you using?(date)

Try flashing only the rom and see if it boots
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Demianis:
After the first flash (only with factory reset) there was some dialpad where I could enter a emergency number. But shortly after the phone went into a bootloop again.

Then I completly erased everything and it´s just looping now.

I use the link from the first post, which is lineage-17.1-20200205

thx
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tech_infinity:
Did you wipe system and data before flashing?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Demianis:
yes, system, data, cache/dalvik, factory reset and format data.

I´ve tried already with latest twrp 3.3.1.2, lineage-17.1-20200421-UNOFFICIAL-h930, Havoc, magisk 20.3 and other nikgapps. No success.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] lallolu:
Try the "Format Data" button in TWRP.

[MENTION=3475147]SGCMarkus[/MENTION] I've been using the 0421 test build for almost the last 4 weeks. During the first 2 weeks, I missed my alarm 3 times because the phone went silent (and stayed silent, unable to produce any sound at all in any app, until I rebooted). That never happened with a previous build, so I looked up the changes to build.prop that you made to try to address audio issues. I decided to set persist.mm.enable.prefetch back to false, saved and rebooted. Since then, and it's been about a week and a half, the problem hasn't reoccurred yet. I can't be sure if that setting is to blame, because I can't duplicate the issue without just waiting for it to happen, but I've waited long enough that it looks like it could be.

Edit: Nope. The problem reoccurred this morning, so it's not that setting. I'll keep testing.

My phone heats up while charging. Using original cable and charger that came with the phone. Battery is at around 80% health. But im scared it will deteriorate faster now. :/ Help?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] talla23:
Okay guys. I have a couple of issues with this ROM. This is my first custom ROM ever and I'm not experienced in this field, so pls dont flame me for being stupid, I know I am hahah

I have installed the magisk hideprops, busybox and immersive navigation bar for the Magisk.

I can install Netflix from playstore, but I can't play anything. It just gets stuck on the loading screen for the show when I click a title. I haven't still found the same issue as mine anywhere.

My USB tethering is not working.

I can install banking apps, but it just exits them when I try to run them and it says to me that the app is unable to run on a rooted device (even tho i have activated that Magisk hide stuff)

When I connect my Bluetooth playback device (headphones or speaker) in a running youtube app, it always freezes for couple of seconds, and crashes 80% of the time.

My phone gets hot while charging, never did thst prior to installing custom rom.

When I have media playing on play music, I have screen off gestures of stoping and skipping tracks even tho I have disabled those in the settings. Its quite annoying when in pocket it randomly skips track.

There may be some more minor bugs, but I can't remeber them now.

If anyone knows how can I fix any of these, it would be awesome. I have tried some foxes for USB tethering, mainly the one from the Q/A here, but it doesn't work, I can't seem to find any LGE drivers to install on my computer.

Thank you.

And if there is an Official version of Pie or Android 10 anywhere, I would be grateful if you could direct me to it. Bcs of these bugs, I'm thinking of going back to stock even tho I like the rest of this ROM.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
You had to be on stock Pie first to install this ROM or you will have tons of issues. What firmware were you on before you installed this ROM?

Yes, we have "official" Pie KDZ and TWRP-flashable zips (ROMs based on KDZ) for most major variants. What variant do you have?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] talla23:
I was on the latest software for H930 - stock pie. Not sure about exact build numbers. But it is unlocked European model, so I guess I was on the latest build
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
Thats why i told you to force an installation, you dont select "search for drivers" (neither internet, nor locally somewhere), but you directly go to the menu, where you can select a device category/manufacurer and then a device...
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] talla23:
I'll try once more when I get to my laptop.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
OK. For H930, if you want to go back to EU H930 Pie stock firmware, see TWRP flashable zip in this thread:

https://xdaforums.com/lg-v30/development/h930-lg-v30-european-market-t3951898

Thanks to our Devs, we have TWRP flashable zips (ROMs) for all major variants built from stock image KDZ.

I have made a backup file while I was still on stock rom to the SD card. Could I use that?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Is it a TWRP recovery backup file? If so, yes. You can boot into TWRP and restore that file.

If not, then just flash the zip file I pointed you to, and reflash Magisk. It's like flashing a ROM but it's stock firmware. You'll still be rooted, you'll have DTS Surround Stereo, etc.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] talla23:
I made the backup while in TWRP recovery mode, so I hopet its TWRP recovery backup file hahaha I'll check later - have an exam tomorrow. Thanks for the help.

Is LOS 17 available for h932, or is there a firmware patch as for Android Pie ROMs?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
No. Read Question #4 in the V30 custom ROMs FAQ.

FAQ ON AOSP/Lineage/LOS-16 & LOS 17.x CUSTOM ROMS

T-mobile H932 can only use the LOS-16 based ROMs. LOS-16 itself has daily builds for both the "universal" H930 and the T-mobile H932 specific.

Twice in the last few weeks, I discovered that my phone was no longer connected to my WiFi and was unable to re-connect. The issue is just like what I experienced before flashing an Oreo modem/Jett's Magical Backup. I tried toggling WiFi, re-saving network credentials, rebooting and re-flashing both the Oreo modem and Jett's, all to no avail. What ended up fixing the issue was simply rebooting my router. Your first guess and mine would be that there's a problem with my router, but I had no connection issues with any of my other WiFi devices. I could toggle their WiFi and they would connect, all while my phone couldn't. On top of that, as I said, the phone's behavior (repeatedly trying to connect and failing, then giving up) was exactly like what the Oreo/Jett's modem originally fixed, which leads me to suspect that the issue is still with the ROM.

Anyways, I'm mentioning this for two reasons:

1) If anyone else has the same issue, try rebooting your router.

2) Maybe this will give a developer an idea of how to fix the WiFi issue for good.

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] jkim204:
Thank you for the quick response. Any idea on when the OTA updates will be available? I fell in love with LOS but just find it bothersome to reflash the updated roms every few months..
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Osprey00:
It hasn't been updated since the Spring, so my guess is that Markus has moved on, which is perfectly understandable. ShapeShifter499 has seemingly picked up where he left off, so people who want the latest LineageOS should probably switch to his builds:

https://xdaforums.com/lg-v30/development/rom-lineageos-16-0-lineageos-17-0-wip-t4042333

I, personally, have switched to Havoc-OS, which is just LineageOS 17.1 with some extra features (like extra configuration options and smart charging).

Hello Blank97, I know it's some time gone since your post, but I encounter exactly the same problem as you described and can't find a solution. The only way to fix my wifi I could find was flashing a backup of an old modem, however this destroys the fingerprint reader functionality. Restoring my recent modem backup re-enables the function of the fingerprint sensor, but then wifi is again not working. So, with which variant did you fix your problem?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Blank97:
1)You can use the WiFi fix that's on the LG V30 Update channel on telegram, should be the easiest because it's just a zip that need to be flashed in recovery.

2)If you don't solve it try and fix it this way. (this wasn't available when I had this problem).

https://xdaforums.com/lg-v30/how-to...n-variants-t4012635/post83468045#post83468045

3)I solved the issue using this backup: https://drive.google.com/file/d/1-OVfDU6Iah7rBcGz1dQ_m72LnRx_syjx/view?usp=drivesdk

But remember to do the same steps that I explained with the Persist partition on the reply you quoted.

When I had this issues the first two option didn't exist so go with them.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] blcky05:
Thank you very much for your reply!

Sadly, none of the points fixed the problem...

I already have tried the first two options, however, they don't fix my wifi. Maybe that's the case since they are intended to be used with the north american variants of our phone, but I own the european h930.

I also tried your process, but no matter what I do: As soon as I flash/recover one of the older modems, my fingerprint sensor stops working. Also restoring the persist partition doesn't change that. The behavior of the one for which you sent the gdrive link is also the same.

Did you do a full wipe afterwards?

So, if anyone has some more ideas how I could fix my wifi with pie modem (or why the presented fixes don't work for me) OR how I can fix my fingerprint sensor with oreo modem, please let me know!
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tech_infinity:
Try this file https://xdaforums.com/showpost.php?p=83695107&postcount=144

After changing modem did you remove the fingerprints and then added them?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] blcky05:
I tried both versions of the files without success. I also had a look into the scripts and all there is done is setting-up the symlinks, however these already exist. Without touching the persist-lg partition, the wifi is functional or not only by changing the modem. So, the symlinks itself can't be the problem, only their destination may be?

I can't delete or add any fingerprints after changing the modem. The same message appears like in the original post of Blank97. May be some type of permission error?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Blank97:
Remember to use the persist partition of an Oreo stock rom/aosp Pie based rom for the H930 and not the one of Pie stock rom/aosp based 10 rom. The Persist that I used was from a backup that I did with an aosp Pie rom before flashing a stock pie rom.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] blcky05:
Oh okay, that wasn't clear for me. Well, then I'm in trouble :D I do have an own backup of stock oreo, but for some reason the persist backups are missing. I must have forgotten to tick them :cyclops:

One thing I could try then is reflashing the whole oreo stock ROM and modem again, do that backup and return. But I'm not sure wether this will have success, because I'm wondering if the OS can modify the persist partition? My understanding of the Android OS and its partitions is not deep enough, but If it can't, then the persist partition will stay the same as in the backup I am currntly using and the whole rollback won't make any sense.

But also the other way to the goal, fixing wifi on nougat modem, is driving me nuts. It's very strange, but wifi is working straight after boot for a short time until the mobile network connection is established. So, how does the mobile network connection influence the wifi connection? Shouldn't this interaction be handled by the OS instead of the modem?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Blank97:
This whole thing of the broken WiFi with the Pie firmware is poorly understood in the first place, I remember a developer saying that he had 2 identical H930 that went through the same steps, ending on an AOSP 10 ROM. One one them had WiFi working, the other didn't.

Btw in the evening I'll give you the persist partition that fixed it for me, then you can try with that one.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] blcky05:
Okay, that sounds really strange.

This would be very nice, maybe it can fix it. Thank you!
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] blcky05:
I've been able to solve my fingerprint sensor error. So, quick update for everyone who has the same problem:

After flashing the modem, I had to manually delete the fingerprint database: /data/system/users/0/fpdata/user.db

Registering new fingerprints will then create a new database. Flashing a persist backup didn't do the trick for me.

Hi Everyone. Has anyone got any suggestions for me I am having a problem with the WIFI on LOS 17.1 using LG V30 H930G.

I have performed the recommended steps to fix (Flashing older oreo modem.img and new kernel base then '[RECOVERY] WiFi_Fix_LG-v30_v2.zip' and nothing has worked so far.)

I have not tried Zach's fix as I don't know what terminal app to use for the commands and can't download one as I have no wifi or data to download.

Please can anyone try suggest how I should proceed going forward as you can't roll back to LOS16 once flashing the STOCK PIE.zip. Either fix WIFI or what other ROM should be used instead of LOS 17.1? When I reflash the H930 31a Stock Pie .zip in TWRP I cannot boot it is saying No OS installed?

Please help with how to get the phone usable again..

Tried lineage 18 and it seems mostly fine only issue is that the sd card that i have formatted in NTFS that i was using with LOS 16 it says it is corrupted to force me to reformat same thing happened when i went down to try LOS 17.1. Anyway that i can escape the time waste of backup and restore of so much data?

There is no crystal clear comprehensive procedure on how to install these roms so i use a mixture of advise from different threads.

I first used the pie stock zip to flash (used these instructions: https://xdaforums.com/t/...r-instructions.3790500/page-165#post-79972584) (really post #3,285)

What i did was install LOS18 (not sure why it is not on this website, but it is on another not sure if i can mention). Then opengapps (ofcourse the right selection) aroma and then magisk version 23 (had to find that somewhere else could not find latest magisk on this website) then AKC_RTCD flashed in twrp 3.3.1.2. I essentially used the template of steps in the above link for the LOS 18 and LOS 17.1 install. For LOS 18 i lost TWRP and had to fastboot method to get it back on the phone. LOS18 was missing the playstore app and my aroma selections somewhat ignored as some apps to exclude still was installed. The exact same thing happened with LOS 17.1 except TWRP was intact on the phone.

I had to restore back to my los16 that i was using and my sd card was accepted. Please help.

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] MtnX2:
I am interested in trying LOS 18 when I receive the new LG V30 H932 I just ordered. I don't plan to install the Google Play store or even opengapps. I'll just use F-Droid probably.

My sdcard will be formatted with some Linux fs like ext4 (or maybe just fat32, not sure).

I really love this phone and I look forward to running the latest LOS on it. I hope I can keep using this phone for many years.

I may have some questions once I start the installation process.

I wish the V30 had official LOS support and OTA updates. Do any of you think that could ever happen? If it could happen, what would it require? Would some donations help? I'm willing to donate, but I guess one person would not be enough. Are there enough V30 users to warrant official LOS support?
