original h931 on h931 20q (with 933 partitions) to los17 alpha

Hi.

Just a feed back report if it might contribute:

I have an original h931 which I Frankensteined, wtf, went to h933-20 for partition structure and then h931-20q. Was stable with twrp, magisk20, WiFi, LTE, etc on h933-20q. No bugs.

Flashed los17alpha via twrp. Factory reset and formatted data.

On boot to system, I received the

on the login screen. This indicates 'a mismatch between the build fingerprint in the build.prop file in the system partition and the build.prop file in the vendor image, specifically the ro.vendor.build.fingerprint key.' -according to Google search.

Another very brief error message appeared (too briefly to read properly) that mentioned 'Qualcomm'.

I tried master reset, reinstalling los17a, magisk and rebooted with same result.

I also noticed that it reported a corrupt microSD card. It's not corrupt I think. Anyway, im not formatting it as it has backups successfully read by twrp.

I noticed that Bluetooth works fine.

LTE works fine though slow to reset after coming out of aeroplane mode.

Can't take matlogs as I can't install magisk manager because there isn't a stock file manager and it returns 'app not installed' when I try directly from chrome.

In about menu, Device is listed as unknown, as is WiFi mac and vendor security patch level.

-Maybe this may add to your data.

Keep up the great dev work guys, Los17 is pretty exciting! Please shout if there's anything else you'd like to know, or thing you'd like me to try. Going back to h931-20q for now.:fingers-crossed:

... Continued from above post ^

After failed WiFi on my h931 using los17 alpha, I factory reset, wiped data and restored from twrp backup (Including modem!) and have lost WiFi in h931-20q. Doesn't this suggest the problem isn't the modem?

Where does RIL reside, what partition? I can format that partition and restore again, to rule that out too, right?

---------- Post added at 05:30 AM ---------- Previous post was at 05:13 AM ----------

OK. I checked what I backed up and restored in twrp. It was boot, system, data, modem, efs.

So if those successfully restored, whatever broke WiFi in los17 install must reside in the remaining partitions that I didn't backup and restore, right?

That leave's 'recovery'and 'op Configs'. It's not likely to be contained in recovery as twrp works fine. I've no idea what 'op configs' are. But in guessing it's in there, or somewhere left in the system partition that doesn't get overwritten by twrp restore of 'system'. I didn't restore 'system image', just system.

Is this helpful? Or just mistaken?

Check you have the APN added. I had the same problem and as soon as I looked up the APN settings for my carrier and add in the APN the problem was fixed.

Perhaps it's only me, but since there seem to be some tough problems to solve with LOS 17, wouldn't it make sense to continue with LOS 16 for some time, perhaps based on the latest Pie firmwares from LG?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
The los17 build has the issues because of the pie blobs from LG. Same issues were present on a los16 beta build with lg pie blobs.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tech_infinity:
There is a pie firmware based los16 beta but it has the same WiFi issues.

So it's the pie firmware that's causing this issues.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Ecthelion3:
Thanks for the information, guys. So there's no easy way out ;).
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] dimitrissot:
I dont think its that because some users that come from LG PIE STOCK ROM have wifi working (mostly h930) see the google sheets document in this thread: https://xdaforums.com/showpost.php?p=80535091&postcount=1680
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tech_infinity:
You're misunderstanding. All the users need to use Pie Firmware to be able to use los16 beta and LOS17 which means that all the users are coming from LG STOCK PIE ROM.

Los16 beta, Liquid Q and LOS17 are using Stock LG PIE blobs

Los16 and all other Pie aosp roms are using Stock LG Oreo blobs

Crazy enough, that worked ? The APN was already in, I guess it just got switched somehow? Either way, that's fixed now so thanks!

H932 LOS16 on Oreo firmware. I've had several hard reboots after a call. I haven't been able to figure out a pattern to it yet Also, speaker phone is crackly and unusable on applications like Duo.

Is there anything I can do if logs are required?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] myhe01:
This is a great rom, and I've been using it for a month or so with only minor problems; I'm hoping I'd be able to solve them here.

One of the most annoying problems is with GCam. GCam wants to CONSTANTLY misbehave and stop working, sometimes popping up multiple prompts every few seconds. Clearing cache and storage don't help, uninstalling and reinstalling with the Play Store and Ti Backup don't help, and the only fix currently is disabling and reenabling to go back to the "factory" version (2.7.010). This isn't really feasible because this version isn't as optimized and doesn't contain things like night sight.

Speaking of cameras, could anyone let me know if they've found a good apk that allows both the wide angle and regular angle cam to take pictures (like the stock LG cam)?

Another small issue I've come across is that my phone likes to sometimes do things without me: it'll randomly restart occasionally, delete an app's storage, or delete entire folders of pictures. I'm not quite sure if it's an app or something with LOS that's doing it, but the only apps I've newly gotten (that have storage perms) since getting LOS are Magisk, Root Browser, SD Maid, and Ti Backup.

Can anyone help me identify what's causing these problems and how to fix them, please?

I wouldn't have to reflash LOS to change my kernel right? What are the benefits of the Ceres kernel?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Kev1venteurfou:
You don't have to reflash, I've specified my kernel in case of cam crashing by your side, that could be due to the kernel.

Ceres is really well balanced between power consumption and performance, moreover it's kept updated.

Has anyone here tested 17.0 on the H932 yet? Would love to test it but this is my daily driver so I'll have to wait for this weekend but I do want to make sure I get a good understanding of what I need to do. First of all I know I need to already be on the official stock, however I already have TWRP and am on a different Pie ROM (Havoc OS) so is it fine to just clean flash the official ROM from this thread via TWRP and then follow the original instructions for 17.0?

Additionally, will the current H930_to_H932 convert zip work for this or does there need to be a new one specially made for this? Lastly, is the latest Magisk 20.0 working despite the original instructions saying it doesn't?

Anyone have any luck with encryption on the LG V30 (any model?) now that Pie is out for it (for LOS?)

Anyone have their calls cut out midway? I'm currently on 20190422, but might be time to reflash anyways to see if that does the trick.

Also, wow LOS 17 already? I might try giving it a flash on my H932.

Hi, I just picked up my V30 so a bit behind on news, I have Stock AUS V20f Oreo on my H930DS, Unlocked bootloader and TWRP + Magisk V20. I would like to apply LOS16 for now as it is my daily driver. Should I update to Stock PIE V30c first? Just wondering seeing as there are pie blobs used now I think?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
NO. Do not update to stock Pie if you want to run LINEAGE-based custom ROMs.

Read the Root Sticky!
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] trevor68:
Absolutely, it was your excellent guidance that got me here!, I read and understand that the reason to not update to PIE was because LOS uses oreo blobs? Maybe I misunderstood that bit. I see LOS16 updated to PIE blobs, so my question becomes does that advice still hold true now?

Update: oh, I misread the changelogs, it is 17 using pie blobs, thanks for correcting me
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
I was just told yesterday the problem still exists.

From one of my KDZ thread warnings:

_____

* ALSO do NOT update to Pie yet if you wish to run AOSP/Linage custom ROMs -- at least for now. See

reason here

. Hopefully, issue will be fixed in near future.

Sure, I'll link to your post. I already say not to update to Pie yet if you wish to unlock bootloader.

I'll also add note not to update to Pie yet if you wish to run ASOP/Linage custom ROMs with link to your post. Then when the issue is fixed I can remove that specific warning.

Atm I'm tempted to return back to stock debloated rom as TWRP-3.2.3-7-default.img can't decrypt /data encrypted on pie
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] seadersn:
it can't decrypt stock pie, too :( anyway, i'm thinking about experimenting with aosp pie in connection with twrp and encryption: filebased is the key word here. should work, but needs testing. goal is to provide a recovery capable of filebased encryption (not activated atm) and a pie rom which is encryptable with fbe, and then decryptable with twrp.

i hope i get my damn pc stable soon... it's tricky, you can run stability tests for two to up to four hours with positive results, but compiling or cpu intensive tasks like rendering crashes it anyway then, in linux faster than in windows. i hate it... when i downclock it, running it below its specs, then it's running: but this shouldn't be the way i am able to use my computers "full capabilities" (which it isn't, it's castrated then), it should run within its normal specs and not below them. and i'm not talking about pbo, this is switched off. f*** it :D wish me luck :)

Bugs on los from my experience and their solution:

1. Hotspot only works on open i.e. no security (on October 5 build, don't remember if it's there on 19 September build)

2. Wifi may or May not work for you

If it doesn't work then try:-

1. Flash oreo modem

2. If oreo modem doesn't work then use this fix: https://t.me/LGV30U/150

even both these steps may not fix the wifi for some.

3. Recent Google Maps doesn't work, use Google maps go or older google maps version like 10 or .84

4. Google chrome works only on Gapps with Webview patched like Nikgapps

5. Doesn't work on H932 yet, no workaround for that.

If the answer is already there, no need to ask...

T-Mobile H932 not working (yet) on Android 20 LOS-17 based custom ROMs is also mentioned both in the Root Sticky Guide and the T-Mobile Pie KDZ post #1.

I'm not picking on this poster specifically. It's just years ago when I started in forums it was required to not only read the first page but usually the last couple pages as well as SEARCHING THE THREAD FOR KEY WORDS before asking redundant questions already answered.

Over in WTF INSTRUCTIONS, people still ask questions like THEIR SITUATION is totally unique no one could ever have encountered before. Like there's no way their question has been answered two dozen times already in the past 1.5 years WTF has been used. ;)

Simple key word search gives you answer.

I'm using the latest LOS 16 and recently bought a wireless charger. Wireless charging works, but is triggered only when placing the phone on the charger. It'll charge up to 100%, but then let the battery drain and never top it off, so I'll wake up every morning to 90% charge (give or take), which is annoying. My assumption is that it's the charger, but I want to make sure that it isn't a known issue with LOS before I leave a poor review for the charger or buy a new one. It'd be helpful to hear if this does or doesn't happen to others. Thanks.

Oh, that's interesting. So, it may not be a problem with my specific charger or LineageOS, but rather with the phone, itself? Thanks for the response. Unless someone else has a different experience, I guess that I'll have to live with it if I want wireless charging.

Flashing a new rom problem

Hey hope everyone is doing well! so i ran into some issues when trying to flash a new rom like this LineageOS rom but everytime i try to flash it works goes through starts to boot but then it just hangs at the lg v30 thinq screen. Bootloader is unlocked using the wtf/frankenstien method. This is whats strange....I already have flashed havoc os on my LG-us998 932 using it now. I also tried flashing liquidremix os with old and new releases & nothing changes, stuck at boot screen. My guess is somehow the data partition is encrypted even tho i decrypted. Im not much of noobie ive done some difficult flashing never bricked a phone. Ive tried all the basics of flashing a new rom. Im scrathing my head because my first flash was a RessurectionRemix which worked fine i just didnt care for the features so i found havoc os & theres nothing wrong with it no bugs no glitches. If you got an idea or had a simulare problem any suggestions i would greatly appreciate!

its us998, I say h932 because I can only flash h932 roms. honestly ive been confused about the varients, I have not seen any rom downloads for us998. Its either h930 or h932, so your telling me H932 is not even my model?

H932 versions of ROMs are for the H932 only. The H932 has a different RSA signature. The H930 version of a ROM is for the other variants. If I flash an H930 ROM to my H932, it will turn this phone into a paperweight.

Alright i see, very strange because thats what i initally thought it but with 930 when i tried to flash it gave me a red error on 2 different roms thats why i was leaning towards h932 Ill try again maybe the download got corrupted or something. Thanks for your help

Read post #2 in particular.

All AOSP/LOS ROMs are called H930, but are compatible with all models EXCEPT for T-Mobile H932. But there's workarounds for T-Mobile H932 on LOS-16 ROMs.

IF you have US998 then you definitely don't have T-Mobile H932 and please never flash anything meant for T-Mobile H932.

Hopefully I can send you some PRs soon...

Best regards :)

No real clue what might cause it... I thought of switching to the stock wifi stack, to try that one :confused:

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tech_infinity:
Hey :) ,

I'm going to share what I know and have gathered from others. All this could potentially be of no use as I'm not a dev. Hopefully something will be useful here.

I have also attached 2 excel sheets which should be self explanatory.

Also another text file from a user and his experience with h931.

The problem with the Wifi issue is it does not seems to have any pattern as people with the exact same model and software have different results with WiFi.

For some people wifi works without doing anything extra.

There are 2 ways to fix wifi for those who have broken wifi:-

1. Flash oreo modem

2. If oreo modem doesn't work then use this fix: https://t.me/LGV30U/150

Even these two don't fix the issue for everyone but works for some.

Also, there's probably something deeper because even stock rom had some wifi issues with custom kernels. People with the exact same model and software with the same kernel, one has wifi working while for other it is broken.
