I bought a used V20 Sprint and plan to install LOS. Do I need to activate the phone to Sprint on original ROM first or can it activate on Sprint via LOS?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] WhiteWidows:
I activated on Sprint oem rom first not sure if that is necessary. . But you don't want to update the stock rom past a certain version otherwise the dirty santa exploit won't work and will be forever stuck on stock. Unless they fixed that. You might want to check the dirty santa thread first and see what version the phone is on.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
Use dirty Santa to root. That will install TWRP and then flash the Sprint dirty Santa rom per the instructions. You'll be able to back up EVERYTHING. Do that because you'll need your EFS for every AOSP rom or you can't make calls. Also update your prl and profile w/ dirty Santa Sprint room. LOS will get better data connection if you do that first. For wifi, flash LOS 5/3/2017 first. Then update to the most recent.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xenokc:
So can I activate phone on Sprint with Santa Sprint ROM? I plan to give phone to relative eventually and will need to reactivate to another Sprint number at some point.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
I can't say for sure because my Sprint phone was already activated when I rooted it. But since it's stock you must be about to. I've called Sprint and they can't see the root when you're on DS SPRINT ROM, it's as if you're on the original rom from their end. The store would see the difference though.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] philiptibbs:
Or do what I did if you have insurance just smash phone and say it was stolen and get new one in mail for $150 LOL I have a new stock LS997 and soon gonna trade it in for a S8+ or NOTE 8 .
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
LMAO
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mmmmmmmma:
Do this. Flash DevDigitel_ZV7_V9D_Rev3 ROM, let it boot all the way, call Sprint to activate phone (you'll need your ICCID and IMEI, you can find this on the About section of the phone), once active, update PRL and Profile, once PRL and Profile updates are successful, reboot into TWRP and flash LOS w/gapps. You can also chat Online with Sprint if this is the only Sprint phone you've got. Yes, you can switch numbers at the later time, just repeat this process with the new number. Let us know how it all goes.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xenokc:
^Thanks!

I see a lot of different kernels about. Any recommended for LOS that also works with Magisk?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Obamaloominaty:
For US996/LS997, Gamma Kernel is the best imo. Any other variant and you're probably better off with the kernel Lineage comes with.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] pentium0:
Slow boot time on h918:

Lineage has been working great for me overall.

I have really slow boot times, like over 1 minute. It also stalls for a long time rebooting into TWRP.

Is this normal?

Would restoring to stock, rerooting, etc help this, and the weird Bluetooth behavior I get?

Is there a newer baseband? (See my attached screenshot)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] TopHATTwaffle:
Currently the device is running over all snappy during most tasks. Currently getting audio stutters along with video stutters. When this happens the entire device hitches. For instance I'll be typing a message and the audio with stutter along with the device basically freezing for a second or 2 until the music comes back

Clean install on the Jan 9th build.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] WhiteWidows:
Use Gamma Kernel if your variation is supported.

I've made the mistake of updating ROM through OTA and now getting the recovery boot loop. I saw instructions to wipe and start over but is there a way to fix w/out wiping out data?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
Don't wipe all of the misc, only partial:

https://xdaforums.com/showpost.php?p=70474540&postcount=12

If you wipe it all you'll lose your WiFi mac and BT addresses.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] emdroidle:
There is a thread (now with bounty!) for getting the second screen operational in AOSP. Some additional work will be required to get that operational in LineageOS, but I doubt that will be much of a problem.

In other news there is reasonable hope of having the 4.4 kernel operational on the V20.

Worse, for the H990 you'll end up with a broken modem, at which point it won't really be useful as a phone. A workaround for fixing the modem will be shipped, but it isn't well tested.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mdl054:
Awesome thanks for the heads up, can't believe I missed it. Added myself to the bounty. Very cool feature. I don't use it for much but I love having it for the music controls when screen is off plus starting the flashlight easily when I'm one handed.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Phoenix591:
I'm curious, can you elaborate further?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mdl054:
Also interested about the kernel. Is it true that Quickcharge might be easier to implement with the 4.4 kernel? I read that somewhere and can't for the life of me find it. Great work on this for sure.

[MENTION=2881807]x86cpu[/MENTION]

I am back after a new test-marathon.

Steps i did:

1. Flashed newest weekly us996

2. ROOTED / Flashed addonsu arm64 instead of supersu (BTW. WORKS GOOD / WITHOUT PROBLEMS)

3. Mainly installed Magic Earth and GPS Status... TEST: Magic Earth and GPS Status worked good

4. Installed and configured Firewall... TEST: Magic Earth and GPS Status worked good

5. Installed all my Apps except the Autostart-Manager (All in One Toolbox)... TEST: Magic Earth and GPS Status worked good

6. Installed and configured the Autostart-Manager... TEST: Magic Earth and GPS Status worked good

7. Installed Google Text to Speech... TEST: Magic Earth and GPS Status worked good

8. Installed Titanium Backup root and deleted "OK Google Environment" and ALL Verizon (VZW) and Sprint Apps and the Weather App... TEST: Magic Earth and GPS Status worked good

9. Set all my privacy settings... TEST: Magic Earth and GPS Status worked good

AND NOW:

10. Inserted my Vodafone SIM-Card, booted... TEST: Magic Earth and GPS Status worked NOT good !!! (same as i described before... you can read it here in the "hide" area of this post)...

So i removed the SIM-Card... TEST: Magic Earth and GPS Status worked good

After that i inserted the SIM-Card and activated the AIRPLANE-MODE... TEST: Magic Earth and GPS Status worked good

It is the most freaky issue i have ever heard off...

BTW. With WETA and ALPHA Rom (stock based) and all the same steps like above there is not this issue... Only here with lineage, so it can not be the SIM-Card (the problem producer).

Any idea?

EDIT:

After googling some time for "sim card gps issue" and "airplane mode gps issue android" i am not the only one with having problems about inserted sim card (no airplane mode) and a good working gps connection.

At weekend i will do a short test with the sim card of my wife (a reseller sim card / another provider). Let me check and report....

But the freaky thing is, absolutely no problems with my vodafone sim card and all the 10 steps on a stock based rom (for me Alpha Rom) on my v20.

EDIT-2:

The new SIM-Card (the contract) of my wife will first start on wednesday, so i can test it with the other SIM-Card on wednesday initial, but after some more googleing it seems, it is not a problem with a SIM-Card especially. Directly, when the phone gets a provider signal, the gps functionality goes bad. On airplane mode no problem. And the people, who report the same problem like me (even one person here on xda too) did not all the special configuration like me. Unfortunately not even in one forum/board there is a real solution :(

Bluetooth stuck on searching

I tried everything from restarting to clearing the Bluetooth cache but my Bluetooth is always just searching

---------- Post added at 08:22 PM ---------- Previous post was at 08:18 PM ----------

Finally figured it out , go to settings under wireless and networks go to more then "network settings reset"

This fixed the problem
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] CM-Tester:
For everyone, who is interested in: V20 with LOS can be rooted with addonsu too... Not only with magisk and supersu. Works very good on my v20 us996.

Actually its still not working for my H910; it just says no devices found the network reset just got me to this message

Hi, sir. Seem like the rom don't have any option toggle for the quad-dac. So how do i know it's still working???? Thank you for your time
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Obamaloominaty:
Use the V10 DAC enabler on the play store.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] tesna:
Hey, does anyone has the correct procedure flashing this on H918? I downloaded latest lineage-14.1-20180130-nightly-h918-signed.zip and nano gapps, in TWRP (after wiping system/data/cache of course) However after a reboot, after the LG logo shows up I just got blank screen.

Download the file twice and flash it again still the same result. Hmm
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] CM-Tester:
Don't know, if it helps you... But everytime i flash lineage, i wipe everything incl. Internal data (excluding external sd and usb otg)... Then flash weekly and try to flash root (supersu or addonsu or magisk) too (with add more zip...). And if the problem is still there, maybe wipe everything again, try to format data in twrp, wipe everything once more and flash weekly and your root choice again. One time that was the trick for me, to get a working bootup. But as i said, don't know, if it helps you. Do it at your own risk.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] tesna:
I did clean flash, including formatting data, only microsd remaining, still no luck. Perhaps there is error on the last build? anyone else who use h918 able to clean flash latest build? I flashed zip based on stock rom and it booted fine.

Perhaps I should try flashing older build or unofficial build.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] CM-Tester:
Hmmm i have a us996, so i can´t help directly. Maybe you really should try a weekly from the week before.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
Which TWRP did you use?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] tesna:
Iniitially I use twrp-3.0.2-1-h918, perhaps the TWRP is outdated so I flashed twrp-3.1.1-0-h918 (the newest TWRP I could find here in xda for h918) and flash LOS again but no luck.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Obamaloominaty:
Are you using a stock based kernel?

Try using a kernel based on AOSP, Gamma Kernel has added H918 to their downloads, so I'd recommend that. There might be another kernel out there, but since I don't have an H918 I haven't looked into it.

If that doesn't work, I'd try an unofficial build.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] esalce:
Verizon

Any Verizon using this has a daily, and how does it compare to a stock Rom, I know 2nd screen is gone (something that i am not happy about) but can deal with it. I use Bluetooth in the car and sometimes a headset. Looking for a better battery. Any insights would be helpful, thanks in advance.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Alibaba0101:
Sorry if I'm stating the obvious, did you wipe system too before flashing lineage?

https://wiki.lineageos.org/devices/h918/install

Select Wipe and then Advanced Wipe.

Select Cache, System and Data partitions to be wiped and then Swipe to Wipe.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
I'd try one more time with 3.0.2.1 and go into TWRP with the button combo. Then do your normal wipes but include repair file system; choose system.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] tesna:
I tried to flash again last night with multiple combination (last few weeks of officials, non officials, with custom kernel, with or without gapps) but still gave me no luck. But the officials and the non officials gave me different symptoms tho. While the official build gave be black screen (with flickering backlight), the non official one just reboot it to TWRP. hmmm. I make sure that I wiped completely every partition, excluding the microsd card.

I just kinda gave up and decided to back to rooted stock by flashing stock twrp flashable 10r zip, it worked, until I left home (my home got wifi) and noticed no mobile data. Couple flash and reset thru TWRP later still no luck making the mobile data to work (regular phone/text/wifi/everything still works normally). The SIM card is fine, tried on other phone the mobile data is working properly , tried other sim on the phone also no luck.

I had to use the last resort, flash KDZ using LGUP. Thankfully the mobile data is back..... but I'm very sad that I'm losing root forever (unless new method is found.....) ah well....
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
h918? Someone else with a h918 could chime in, but a 10r changes the boot loader which is not compatible with Lineage, and unfortunately I don't think there is a way to get to an earlier one. But I hope I'm incorrect for your sake.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Alibaba0101:
I have a new lg phone that i was going to try lineage with. Haven't gotten around to it yet. Will be interesting to see if i have similar results. You could have used lgup to 10j, rooted and then used the rooted 10p roms using twrp. That way you could still have root on stock rom. I prefer lineage on my moto x pure though as opposed to stock. Stock never gets the necessary security updates.

---------- Post added at 07:58 PM ---------- Previous post was at 07:54 PM ----------

I have an h918, but i haven't gotten around to putting lineage on it yet. I don't think you can have twrp and 10r can you? In order to get twrp and root you have to be on on 10j. I assume if you use 10r recovery it will re-encrypt your phone making twrp useless (I'd assume stock would also over write recovery)...and i don't think the 10r custom roms to be used with twrp include new bootloaders do they?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] tesna:
Yes, this also I'm suspecting, incompatible bootloader. Unfortunately no rolling back to earlier bootloader (hence I'm saying I lost root forever). What version of bootloader of H918 is compatible with LOS? We need to put this to prevent others users facing the same issues as I did.

You can have root on 10R, as long you flash using dimm0k's 10R flashable zip. With this you update everything, except the recovery is still TWRP.

If you want to try LOS I suggest do not update from 10J. I learned this the hard way lol (well, thankfully not hard enough, at least I can still use my phone, just lost root :))
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Alibaba0101:
Thanks for the feedback. I was tempted to flash 10r and try out the newer modem. Guess I'll stick with 10j then. Without root, this phone would be useless to me. The whole point on getting this phone was the unlocked boot loader and ability to root the phone.

---------- Post added at 06:58 AM ---------- Previous post was at 06:55 AM ----------

NO GPS LOCK

/COLOR]well my stock worked perfectly; then I flashed LOS and poof my GPS was gone; I reinstalled stock then dirty flashed LOS (cuz i heard this fixes GPS issues sometimes) and my GPS worked but in a kind of weird way; very inaccurately. So I got GPS GPS status and cleared and updated my GPS info and went outside and my phone locked onto over 20 GPS satellites! This was from walking outside though; I'll still need to drive around to see if the accuracy problem is solved

Another thread on xda says it is possible to flash LG fm radio app from a AT&T H910 on the US996 with stock android. Have you tried that once (i know you are using lineage os now)?

Which V20 version is best for someone who buys the device now in 2018, is it still US996 because that is easily rootable with the official bootloader unlock or is a H990DS with latest firmware also a possibility since that hardware offers fm radio plus dual sim on top?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] emdroidle:
If LineageOS is your goal, the US996 is a much simpler target. The H990DS is likely to have LineageOS available in the near future, but it hasn't happened yet. This is being actively worked on, but "soon" could be 2 weeks or 6 months.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] CM-Tester:
US996 is the easiest to unlock the bootloader and free for worldwide carriers...

H990DS meanwhile can be unlocked and rooted, but there is NO custom rom for it...

So if you want to flash custom roms, MY choice would be the us996 ;)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Nebenfluss:
Thank you. I am asking because i am hoping for a combination of Lineage OS + working FM Radio - a real rare combination these days :) But since the days of the LG G4/ G5/ V10.. FM Radio was no longer supported by LineageOS. I am still enjoying LineageOS + working FM Radio on my LG G3 D855. So i am still hoping for a newer device to achieve that, too. Thanks again for your hard work in supporting the Lineage OS Development!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
FM won't work in Lineage.... the kernel drivers were ripped out in favor of better Bluetooth stability. I tried to put it back one time, but blutooth kept crashing on me....
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Nebenfluss:
That is very interesting. I always assumed (am no developer, just a user) that lagging fm support in lineage os was due to proprietary broadcom wlan fm combo chips and missing driver for it? Since there are devices with a qcom fm chip where fm radio is supported even by lineage os: lg g3 d855, moto g4 play, wileyfox swift. Also in the galaxy note 2 with lineage os one just has to add the spirit fm app by mike reid and instantly fm radio plays since the lineage kernel supports it.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
Code and driver is in the kernel. Some Sony devices have it in them. The bt driver is used for fm too (high level), so when i added it back bt sucked again. But maybe sometime it can be revisited. Right now I'm testing some charging improvements on the v20 (thanks [MENTION=5103965]Omar-Avelar[/MENTION]), and trying to bring back normal speed charging for the g5.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
Since you mentioned the g5, we have 2 Sprint models in our family. I guess there's still no love for them yet or is there root now?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Obamaloominaty:
I don't know if this is known already, but I figured I should mention it just in case.

So you know how if you turn on Battery Saver the screen gets all messed up? Well I set my resolution to 1080x1920 in adb and it fixed battery saver. No screen issues or anything else that was off. If you know how this fixes it you might be able to fix it when running at native resolution.

I talked to him and he told me he only has a single V20 which he uses for his main device, so I was wondering if people who use the V20 would kindly donate to him to get a development device so that he can improve quality and waste less time and not affect any personal life!

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Phoenix591:
Hmm interesting, I honestly forgot about that issue.. I don't have any problems with battery saver on my us996 with partial panel update disabled in the kernel. Of course my particular us996 is weird and has horrible flickering on the normal Lineage and Gamma kernels that have it enabled.

Course the V20 is a weird phone in general, it seems the clock on most but not all of them is set to 2064 by default (according to the ats files in /data/time and /persist/time)'
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Obamaloominaty:
That's odd... I take it you unlocked using DirtySanta? I unlocked using the Developer Portal from LG and I don't have the flickering issue unless I set the nighttime color temperature to a specific number or if I use battery saver on native resolution.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
If you can unlock the us996 via LG, you won't have the flicker on boot. If you use dirty Santa, you'll get the flicker. If you have the US Cellular us996, then you have to use dirty Santa and will get static on boot. The us996 is different from the other models, as the others you use dirty Santa, so we can adjust the panel to not show static on boot, however there is only a single us996 model so we pick the one that can be officially unlocked.

I found hairline crack right over the proximity sensor a couple of days after this post. That was causing all the problems. Finally got the parts from a reliable supplier and fixed it. Wasted a lot of time with an eBay seller. Had to send it back.

Removed

---------- Post added at 01:58 AM ---------- Previous post was at 01:56 AM ----------

I think the last update bugged out my phone app. Lift phone to ear; screen off just like it should. But remove from ear doesn't turn screen back on anymore. Thought it might be my proximity sensor but flashed back to stock and it's fine. It was fine up until the last update too on ls997.

Update: I think I fixed this by wiping the data in proximity handler 7.1.2 apk. Used TB to back it up and wipe data.
