Upgraded from 16 to 17.1, lost recovery, stuck on fastmode

I successfully installed LOS 16 and it worked. Then I dirty flashed LOS 17.1 and now it boots to fastmode , shows the following info :

Product Name - msm8996 64GB

Variant - msm8996 64GB

HW version - rev_10

Bootloader version -

Baseband version -

Carrier Info - N/A

Serial Number - LGxxxxxxxxx

Signing - production

Secure Boot - disabled

Lock state - Locked

[1120]

[1170] Fastboot mode started

Now what are my options to get back to a proper ROM boot?

PS -> From beginning I was getting "Your device has failed routing safety check warning". But everything was working and I was able to install LOS 16 successfully. But as soon as I tried to upgrade to 17.1 , I am unable to boot.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] G U C C I:
Did you have Magisk on 16.0?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vortell:
Unless you are on f800l and are using beta there is no official pie release I know of. Honestly though this is for guide section and I will not respond again here. I'm not going to rewrite a guide that is already in the guide forum. Outside LG beta all the answers are all written down in the guide section including using modded LGup and partial dl. Hint hint cough, be careful. Also not many can help with beta pie from lg. Most the people don't have it yet. Maybe post in thread about beta pie for f800l if that's what you are running.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] intellignt_idiot:
No. I was on latest Magisk 20.3

Thought of flashing stock firmware. Flashed H910PR10j_00_1205.kdz as I read that it works on H910 model.

So I flashed it using "Upgrade" option in the Uppercut. Now it is stuck on red "Claro" logo. Nothing happens.

And now can't enter into recovery mode. Just download mode is available and I do not know what to do now. :(
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] G U C C I:
Fastboot and flash recovery again. Then clean flash 17.1.

EDIT: And you probably went into fastboot because one of your modules wasn't compatible with Android 10. Same thing has happened to me.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] pentium0:
Bump-

I wonder about that too.

I believe on Los 16 it is definitely enabled with gamma kernel, but not sure on Los 16 stock kernel.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] G U C C I:
Pretty sure it was added into the stock kernel way in the past. And obviously Gamma has it.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] intellignt_idiot:
Now the problem is , I can only access download mode. No fastboot anymore after I flashed stock as I mentioned in my above comment.

Iknow it is not the correct thread to ask this question, but in case you know the answer as to which stock ROM should I flash for my H910 model.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] stingbandel:
Does this rom support volte? Thanks
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vortell:
No custom one does on v20 LG won't release sources. So it's not likely to change and no vowifi. I think you could have found this out through searching the thread. Didn't try just a heads up. :highfive:
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] G U C C I:
No, nor will it most likely ever. It's clearly stated in the OP as well. It's proprietary software so we won't be able to use it.

If you want to use fingerprint reader when you eventually get to Lineage then download a Nougat build.

Anyone know why Pokemon Go doesn't work with this rom? Progress bar loads all the way but doesn't load past the splash screen
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] michaeljh9:
h918 user here. I am currently trying various things to get the game to run. On unofficial 16 and unofficial 17.1, installing Magisk 20.3 installs. However, inside the Magisk Manager, ctsProfile consistently comes out as false. However, other apps that check SafetyNet work so go figure.

On an h918 I have that's ARB 0 running the last official Lineage 14.1 (build is February 2019), Magisk is installed, ctsProfile passes, and Pokemon Go works. However, if you play the game for several minutes (randomly changes from a minute to may take 10 minutes), you are later confronted with the invalid software message.

I offer my experience as hopefully helpful datapoints until I can figure out the combination of making the game work consistently.

strange vs995 issue

Hello. I was encountering a strange issue where I could not boot custom roms greater than 8.1.. I tried RR 7.0.2, LOS 17.1, LOS 16 and all of them would get stuck on the boot animation and after about 10 minutes, it would boot to twrp. I tried all the Gamma kernel verisons, countless wipes, Full KDZ Restores (13A), different twrp versions, dirty flashing various versions on top of 14.1 and 15.1. The only thing that i've found to work is clean flashing RR 6.2.1 SSDEV Version and dirty flashing 16, then 17.1.... Everything works great (Camera, Flashlight, Data, Wifi, Fingerprint, GPS, SMS)..... But as soon as I flash Gapps, It gets stuck on the boot animation. Has anyone has similar issues on VS995? It's the 64GB model currently on AT&T. Anyone know what gapps package works best on VS995 on LOS 17.1? Thanks in advance!!!!! :D
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] michaeljh9:
Stay on latest TWRP (3.3.1-1).

Recent Gapps are currently not working on Pie. Read here. If you use a 9.0 build slightly older, you should be fine. If you try unofficial 17.1 + OpenGapps 10, you're fine.

I've had much success running an advanced wipe in TWRP (Dalvik + System + Data + Internal Storage + Cache) and then proceeding to do the install. Try that?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] jacohann97:
I wish I could say I havent tried all of that. However, I do appreciate your advice., I believe the issue is due to a firmware cross flash and partitions being messed up. The phone has previously been cross flashed to H910, H915, and US996. (Which did unlock the extra lte bands for me :D ). I now have a fully functional latest 17.1 rom. THANKS [MENTION=2881807]x86cpu[/MENTION] !!!

Now for the oddest rom install process ever.....

1. Flash latest VS995 Oreo KDZ

2. Flash 13A VS995 KDZ

3. BL unlock using Dirty Santa

4. Clean Flash RR SSDEV 6.2.1

5. Dirty Flash RR 7.0.2, Gapps pico and wipe DC&C

6. flash tox86CPU zip, reboot, and dirty flash LOS 17.1

7. Be extremely confused about why this is the ONLY method that has worked :laugh: and thank x86CPU for this amazing rom port

Does anyone have an Idea on why this not only works, but makes EVERYTHING work?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vortell:
Wait it was cross flashed to all of these? Why? Either way if you think it is firmware issue just flash alpha Omega firmware downgrade. It's same as partial dl in LGup and using kdzwriter. At least it's supposed to be and it's easier and smaller download.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] G U C C I:
I think people cross flash them to get certain band compatibility. (Don't quote me on that though :p)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vortell:
I'm pretty sure that doesn't do anything though. From what I gather Modem firmware is something you can change only with special software and Hardware. Any company who sells qc chipset pays by amount of bands they put in the phone. Some companies still by the full bands then restrict through system software. At least that's what I read in CAF. Those guys know hardware pretty well. Maybe LG built that into lgup with gui hiding it, particularly if Developer lgup is used. I will have to try some time. To double check but I'm pretty sure it doesn't help. I mean I'm still missing a bands from TMobile that didn't come with us996 or h915 of course I don't know if TMobile ever had those bands on the h918...
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] G U C C I:
Yeah I heard it as a rumor and not fact and that we're unsure flashing firmwares actually does anything.

Hadn't seen the camera threads
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] DrRoosterMD:
H918, crashes to recovery every time I try to load GAPPS or Magisk. If I flash just the rom, it works just fine but that's not quite good enough for me atm.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] zed011:
Thanks so I will try to get cts profile to pass. Maybe it says invalid software because it detects TWRP folder or magisk, did you change the package name?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] runningslow:
I had issues with PokemonGo on LOS16 on my H918 (and a few other apps) because my phone would always fail the CTS Profile check. I haven't tried installing LOS17.1, yet, but back on LOS16 in order to pass the Safetynet CTS Profile check I had to install the MagiskHide Props Config module. I believe I used the V30 profile.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vortell:
That's a harder fix, this is probably not the best spot to ask for that. I think there are threads about the official pie in the forum somewhere. I would ask there. LG might have wanted to stop dirty Santa from working though so it might not be out there.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] :
are there in this unofficial release features such as fm radio that were missing previously and not in this one?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] JacobGates:
Flashed and booted on h918, I have a few issues though. I have no camera app at all. I installed the google camera app from the play store but it crashes almost immediately. Anyone know what's going on here? Also it seems the automatic brightness isn't working at all, i still have to manually change it. It says that I can manually set it and it will learn my preferences, so maybe it's still learning? And last and the smallest, I have the setting turned on for the battery percentage to show, but it doesn't show. Has anyone else gotten that to work?

edit: I also just noticed an issue with neflix. at first play store wouldn't let me install it. I had to set the fingerprint with props. Got it to install but now when I start netflix i get this error:

"Device failure occurred. Please restart your device and try again (501.-1019)"

I can't seem to find anything on this error except from Netflix that only says to contact the manufacturer.

edit2: okay, it seems something went wrong in my process. My TWRP is gone (can't boot into recovery at all, always goes directly into fastboot). I think I didn't do something right in the unlocking/rooting process. I will just start over and reflash TWRP and reflash the rom again and update here if it solved my issue(s) or not.

Edit3: okay last edit, reflashed everything and got everything set up. Netflix still has the same error and camera is still nowhere tknhe found. Any camera app I install crashes on start.

I recommend OpenCamera as it's easy and popular but I myself use GCam ports as it's Google's iteration of the camera app.

Hey guys I was wondering, since this ROM and the LG v20 are near perfect with the sole exception of Radio not working would it be possible to add a proprietary blob into the kernel for the radio driver to work ? (User side of course)

I'd be willing to help on this ROM
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hero1985:
Why didn't the developer update this to know the latest status for this rom :confused:

Because it is still accurate?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vortell:
Netflix works fine on every custom ROM I have every tried... Just not hd. Hd on some otherwise you need to learn how to use magisk and hide props and find older copy of Netflix. I currently have it working on h915(same as h910) running lineage 17.1 with magisk. Only think I haven't tried so far is USB c to HDMI with charger. There was a bug last time I tried with lineage that you would have to unplug and replug power when the phone showed at full power. It was a known bug then and I have but heard anything about it getting fixed. These phones make nice tv boxes otherwise. Their antutu score is pretty close to Nexus player. Far greater then most cheap tv boxes you can buy. The g5 for that matter too now. You can buy those for less then $50 now.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
Yes... I ripped it out. It caused to many slowdowns and complete entire phone freeze when it was installed, plus it never worked anyways. So yes, you cannot enable it since it's gone.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xflier:
Thanks a lot for your reply! I also noticed some slowdowns even after you ripped it out. one web page could take tens of seconds. I guess current best luck is the LOS 16.

Thanks again,
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
I ripped it out from 16.0 long ago, before 17.1 even. So it could be unrelated.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] intellignt_idiot:
Finally I was able to fix my issue by Flashing H915 kdz file using LGUP software. Now I am on Lineage OS and using it happily.

[MENTION=2881807]x86cpu[/MENTION], Thank you for today's update! Other than (I presume the February security patch), have there been any additional bug fixes?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
Maybe... The Bluetooth and FM driver are in the kernel... The BT hardware interface is in Lineage. So... If you do you might break BT too get FM working. So if you don't care about Bluetooth maybe. The code is not proprietary... It's in the LG released kernel code, so you can grab it from there.

If you do get it working and get the Lineage portions updated to work with it, I'm open to getting it back into Lineage. Right now the biggest issue trying was the Bluetooth broke, hence the reason the FM driver was ripped out if the kernel and replaced with a working Bluetooth driver.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
Same as the 16.0 thread. An attempt that should hopefully resolve clean flashing issues for working camera/sensors.

Thanks. I found problem, the problem related to Google photos. I see in YouTube. But when I install Google photos the videos in Google photos couldn't play like WhatsApp. I think WhatsApp uses Google photos player by default to plays the videos. If Google photos app will be fix that problem fixes too.

Also if we refresh the WhatsApp with going to recent apps and back to WhatsApp the video playing well. Or lock the screen and go back to WhatsApp the video plays well.

I read in a webpage that video refreshing should be enabled in app. But I think the Google photos player should be fixed
