[OnePlus 8 Questions & Answers] djmcnz:
If you can get to fastboot, make sure you have fastboot set up on your computer and try the following series of commands it might work...

fastboot getvar current-slot

Note slot a or slot a

fastboot --set-active=[B]?[/B]

Where "?" is the slot that's NOT currently active, e.g. fastboot --set-active=b

fastboot reboot

If that works then great, if that doesn't work you can swap the slots back if you wish and continue trying with edl mode (if that doesn't work then raise a support ticket with OnePlus and they can take remote control of your phone to try and fix it).
[OnePlus 8 Questions & Answers] djmcnz:
Interesting, I've never had a problem with --set-active=a/b (e.g. https://www.androidexplained.com/change-active-partition-slot/).

[MENTION=225651]op[/MENTION] - make sure you're using the latest version of the Android Platform Tools.

You can also 'fastboot -aa' or 'fastboot -ab' but I prefer explaining longhand because shorthand commands are easier to get wrong.

Thanks for the guide
[LG V35 Guides, News, & Discussion] cloud1250000:
No prob!

Added OPEN_EU files, but they are untested.. no clue if everything will work... Some people in the v40 community got it to work :)

Good luck everyone :)
[LG V35 Guides, News, & Discussion] issc:
I've completed all the steps (except for lg weather) and I didn't notice anything different in call features until I saw the description of the international roaming setting referenced "outside of US PR etc." instead of "outside of foreign territory or whatever" which indicates a success.

Then I Applied the vomaster.zip from somewhere else (prob the same thing as the OP's not sure) and flipped on wificalling on the settings and got the setup prompt for wificalling from my carrier and later a "wifi setup's been completed" notification, so I guess things are finally good again. Unfortunately RCS doesn't seem to want to cooperate either way =\

Not sure why I did it because korean q on its own was usable, but I did it it anyway and it is nice, performance feels better too but this could be because I went from LG firmware to open_us. Both the incoming and outgoing calls and texts feel much snappier as well and doesn't take 5 seconds to go anywhere. Also it doesn't ask me whether I want to listen to the call recording or not at the end of every phonecalls so that's nice. thank you

-edit

one question, is there any way I can use the korean AOD's? I liked the one that shows calendar and time.
[LG V35 Guides, News, & Discussion] cloud1250000:
odd! you really shouldn't have to flash that vomaster.zip at all if you're located in the US.. honestly.. I don't even know if rcs is available in canada and I'm really not sure how to test this feature.. You might have to toggle wifi calling again if you got the wifi calling activation success notification.. it was the case on my friend phone..

Just to confirm...

volte/vowifi working? :)

ulm or awm?

carrier?

Looks like the calendar is available with the open_ca files... not sure for the open_us.. sorry..
[LG V35 Guides, News, & Discussion] rpgdev:
That file is a zip file with two different files in it, do you mean to rename this zip file to

engabl.bin

?
[LG V35 Guides, News, & Discussion] rpgdev:
After step 5 I started to get some weird outputs.

Seems like that output is normal because I have the rom rooted and twrped right now but I did have to change the active slot to B at this point because otherwise QFIL wasn't able to read the partitions afterwards. Oddly enough that was the only change I had to make, every other command worked as is referencing abl_a even though I changed the active slot to B (and when I flipped the steps to target slot B instead I just got bootlooped).

Everything's looking good so far. I had not been able to setup twrp on this phone so that's welcome. Hotspot wasn't working on Oreo either so that's another good improvement at least for me. Hopefully, this update ends up being a little bit more stable than Pie.
[LG V35 Guides, News, & Discussion] cloud1250000:
omg no, pick one of the 2 files and rename it to engabl.bin
[LG V35 Guides, News, & Discussion] cloud1250000:
sometime, with both fastboot and qfil/edl.. you need multiple try to get them working :)
[LG V35 Guides, News, & Discussion] rpgdev:
😅 that's somewhat ambiguous, I ended up putting the abl_a in the a slot and the abl_b in the b slot. Not sure if they're interchangeable or if that's the reason why I experienced the issue I experienced. Shouldn't be but who knows.
[LG V35 Guides, News, & Discussion] rpgdev:
I'm noticing that locking the screen takes a while using double tap. At least a second or more before the phone responds and actually locks the screen, is anyone else experiencing this?
[LG V35 Guides, News, & Discussion] cloud1250000:
that's odd mine is almost instantly..
[LG V35 Guides, News, & Discussion] rpgdev:
Apparently it was due to my launcher, they're having some issues with that gesture on Android 10.

The Korean Q is solid, I'm surprised that it's performing better than Pie on this phone. Thanks for doing this guide. Anyways, I still get the camera shutter sound any idea as to why? Also, is there a way to disable the vibration for the fingerprint reader when the read is successful? I managed to do it for Oreo but haven't found a way to do it for Q :(
[LG V35 Guides, News, & Discussion] cloud1250000:
shutter is muted when I'm on vibration mode
[LG V35 Guides, News, & Discussion] rpgdev:
Ah, I thought it disabled it on all modes. I didn't get it on vibration. Would be nice to disable it on every mode.
[LG V35 Guides, News, & Discussion] cloud1250000:
Right :p the thing with the korean firmware usually is.. it's not disabled even in silent mode lol
[LG V35 Guides, News, & Discussion] rpgdev:
I see, do you happen to know where is the camera shutter sound now? It used to be \system\media\audio\ui\ but it seems that dir was removed on A10.
[LG V35 Guides, News, & Discussion] issc:
I don't know how to check for volte working, but vowifi is def working at my work with ****ty at&t signals.

awm -> ulm -> korean q.

I get advanced chat features enabled but nothing works =/ maybe its fixable with googling but im reasonably happy with my phone atm, minus lgpay not being accessible for v35 and v30s outside of korea =\

does this work for the velvet ui version of android 10?
[LG V35 Guides, News, & Discussion] rpgdev:
The camera seems to not be recording video, even on 720p mode. It records but the video files are corrupted. Just caught big foot on video but I still have no evidence because of course my Android 10 Q Korean rom got in the way. How convenient for bigfoot right?

mediainfo 20210226_183931.mp4
General
Complete name : 20210226_183931.mp4
Format : MPEG-4
Format profile : Base Media / Version 2
Codec ID : mp42 (isom/mp42)
File size : 44.9 MiB
IsTruncated : Yes

That's the mediainfo for the file and that's all it shows. It's there any way to recover a working video from it?
[LG V35 Guides, News, & Discussion] thandlovsky:
I can confirm the same issue, but I didn't even realize until you pointed it out. So it almost doesn't feel like too much of a loss.

If you want to record video using a camera app and not a social media app like all the cool kids do nowadays, I suggest the Google Camera app. As I can confirm this still works.

The camera app is capped at 1080p, so we loose that sweet sweet storage hogging 4k 60fps. But again, I guess I never really knew how much I never missed it until I noticed it wasn't there.
[LG V35 Guides, News, & Discussion] rpgdev:
I'd agree if I didn't have corrupted Bigfoot footage on my phone as I post this!
[LG V35 Guides, News, & Discussion] rpgdev:
Btw, I ended up settling on the Simple Camera. It keeps 4k resolution although quality is not the same as the stock camera app. Something is different about the end result and the UI is clunky but you do get 4k.
[LG V35 Guides, News, & Discussion] rpgdev:
Sorry for triple posting but by google camera you mean the GCam for the Pixel? Or this one: https://play.google.com/store/apps/details?id=com.google.android.GoogleCamera&hl=en&gl=US honestly not sure if it's the same. Can you point me to the one you got for the Korean Q? Thank you!
[LG V35 Guides, News, & Discussion] iiAustinL:
Switching to the OPEN_KR_OP version has really helped my AT&T signal quality. In most cases, I'm getting full 5 bars wherever I'm at! For example, previously I was hitting 2-3 bars around my neighborhood, now I'm able to use hotspot and reach 40-50 Mbps.
[LG V35 Guides, News, & Discussion] thandlovsky:
The Google Camera App that is ported to other devices;

This is what I use for the V35

https://f.celsoazevedo.com/file/cfiles/gcm1/Gcam_6.2.030_Advanced_BF_V2.2.2beta2.190904.1817.apk
[LG V35 Guides, News, & Discussion] rpgdev:
Thank you, I've been trying some of the cameras there without luck. For example that one you linked doesn't seem like that cam allows you to take pictures. Video recording works but the regular landscape photo camera doesn't.
[LG V35 Guides, News, & Discussion] rpgdev:
This apk works well with the LG v35 config file. As it's been my experience before all those gcam mods leave a lot to be desired in terms of quality.. I think Simple Camera produces better results but if anyone's interested in one that works well for the Korean Q that one does.

If you want to fix the corrupted files recorded using the stock camera app I can confirm this tool works: https://github.com/anthwlock/untrunc it doesn't seem able to get the audio but it does get the video. Using a video recorded with the gcam as the "ok.mp4" works but the videos recorded with the Simple Camera don't.

[LG V35 Guides, News, & Discussion] MasterTec:
I know I'm way late with this but don't reboot after installing TWRP from Magisk... when you rename the one folder then quickly go back to Magisk and reboot to Recovery and you should be good to go.

Another tip... you can install Magisk.apk *OR* flash it like a zip from recovery.. it works both ways. The instructions don't really make this clear. I screwed up on one of my 5 install attempts by installing an old version of Magisk from a zip file that was already on my SDCard because I didn't have the newer version of Magisk in ZIP format (I didn't know I could flash the APK file).

To keep myself from getting confused, I made a copy of the apk and then renamed it to MAGISK.ZIP and saved it in the same folder. It worked great!

Big thanks to @cloud1250000 for these instructions. Being able to use A10 with the V35 has been great. I plan to continue rocking this device for at least the next year. For anyone still using the device, lg released a firmware update back in October to 30D. Probably just security updates before LG turns its mobile lights off. Also, I am willing to share my OP as a qfil flashable image. It saves time and pulls in A10 frameworks not in the NA Pie rom so that the camera works.
[LG V35 Guides, News, & Discussion] rpgdev:
Just logged in* to second what @cmrntnnr said: thank you @cloud1250000! I'm still using the device and I plan on using it indefinitely... security issues give me some pause to be honest but as far as the device performance goes I can't complain and I don't feel the need to upgrade. It's as snappy as I need it to be.

*Man, this "new" xda theme it's disgusting lol.
[LG V35 Guides, News, & Discussion] cloud1250000:
Glad to have helped you guys :p

I've since moved to the v50 and now to the s20 fe 5g.. god these device are BIG...

Anyway, have some happy holidays and hopefully a nice 2022 ;)
[LG V35 Guides, News, & Discussion] rpgdev:
Please share! Or at least share how to get the camera to work (I'm assuming with stock cam app). Mine corrupts video files using the stock cam app, does that fix that issue?
[LG V35 Guides, News, & Discussion] cmrntnnr:
@rpgdev,

An image of OP from my phone is at this link: https://www.mediafire.com/file/970g5mwsl8s0hj7/V350N-A10C-Localized-for-NA.img/file

md5sum: 9f3ab00ff272bb47bd3e231e67b52c09

Flash to OP_a/b using qfil or using dd from terminal in twrp. Be careful and don't forget to take a backup. It will give you a functional stock camera.
[LG V35 Guides, News, & Discussion] rpgdev:
What type of backup you mean? The entire ROM?
[LG V35 Guides, News, & Discussion] cmrntnnr:
The OP partition you will be overwriting. Good to have backups of other critical partitions, too, like efs and ftm.
[LG V35 Guides, News, & Discussion] cmrntnnr:
It seems phones are getting bigger with each generation. It has almost reached absurdity. The size of the V35 is "just about perfect" IMHO. Some of these new slabs won't fit in my pocket.

Have you rooted the S20? I bought an S10e for my wife. It could not pull in a signal in rural places effectively so she's back to her Sony ZX2 Compact. Maybe it was defective. Have to figure something out soon cause it won't work on AT&T after Feb. Do you have 5G in your area?

Enjoy the holiday and be safe!
[LG V35 Guides, News, & Discussion] rpgdev:
I agree, in fact, the v35 is bigger than I would prefer but still relatively easy to maneuver considering the alternatives. I believe phones should be easy to maneuver with just one hand but, unfortunately, looks like that's the minority view.
[LG V35 Guides, News, & Discussion] cmrntnnr:
@rpgdev,

I appreciated and still miss the size and the textured kevlar case from the moto droid turbo. Otherwise the V30 and V35 are superior.

How'd the OP partition work out?
[LG V35 Guides, News, & Discussion] rpgdev:
Haven't done it. I have a knack of forgetting the details of how to do these things after I get my phone the way I like it since I usually stop tinkering with it.. I'll flash it whenever I have time to deal with a possible chaotic fallout lol
[LG V35 Guides, News, & Discussion] cmrntnnr:
Nice to hear someone is still around and getting some mileage out of the V35 and these guides. @cloud1250000's instructions here are great. Thank you for the report.

Despite my best efforts, I was never able to get vowifi working on Verizon. Big Red doesn't give any love to unlocked phones. If you need vowifi, you might consider switching to ATT, that's what I did, prepaid.
[LG V35 Guides, News, & Discussion] rpgdev:
Btw what's the "manual" way of performing the trick you did to get the stock camera to work? I forgot how to use qfil and the other stuff so I'm reticent to flash the image lol.. but I could tweak stuff here locally if it's not too complicated. If you could share it I'd appreciate it.
[LG V35 Guides, News, & Discussion] cmrntnnr:
It isn't much of a trick. The camera and some other apps don't work with Pie NA OP due to version or dependency incompatibilities. To resolve this, I replaced OPEN_US/overlay from NA Pie with the one from OPEN_CA A10 from G7 from cloud.

FWIW, you don't need qfil. You can dd the OP image I shared from the TWRP terminal.
[LG V35 Guides, News, & Discussion] rpgdev:
The thing is I still can screw things up with dd, because I had an issue with the order of the partitions I flashed at the time when I flashed this rom, I think I had to flip the partitions that were flashed because of some weird error so I'm afraid of flashing anything. If there is a way I can do this by moving some file around or something the better, but I'm assuming I'm not that lucky am I? :)
[LG V35 Guides, News, & Discussion] ^I'm_With_Stupid:
Interesting enough, I switched in the US folder for the Korean one while on Superior OS flashed over the 30d rom (what's noteworthy is that it's a custom rom), and not only did that seem to work, but I did not have any issues and did not have to clear data (however I did clear network settings just to be sure). Although I am not sure if this have solved the frustrating lte signal problems I've been having.

Edit:

Just thought I'd leave this here in case someone had an issue like mine, although this is probably carrier (T-Mobile) related rather then rom related.

Managed to finally fix the problems I have had sending and receiving text messages and calls when on LTE. I was able to fix the problem by doing the following. On a stock rom I called once with lte, once without. Then sent one sms with lte, one without. Then one mms (groupchat text in this case) with lte, then one without. It does not have to be an LG V35 stock rom. I imagine this will not apply to anyone who is on a stock rom.

Also of note, for those looking to flash a custom rom, I believe it is actually not necessary to do these things before flashing a custom rom over the korean stock. My oem/op/ folder is empty after flashing a custom rom, and therefore after fixing my connection issues that means it was not the cause of my connection issues.
[LG V35 Guides, News, & Discussion] rpgdev:
Can you please give further detail on how to go about it? I didn't know they had released a Korean Q late last year.. I could use those security updates. I'm already on Korean Q with along with this "MKGA" guide, so that would be my starting point.
[LG V35 Guides, News, & Discussion] rpgdev:
I updated to 30d and used your files but now I regret having an updated magisk. Since then it seems like Google bought out the dev and now magisk doesn't support hide nor satetynet related stuff. Seems like people have done workarounds but doesn't sound like much of an upgrade to me! Is there a way to get the old magisk without having to undo all the setting up I have done until this point?

@cmrntnnr I used your localized .img file on 30d and works great! Camera is fully functional now, thanks!
[LG V35 Guides, News, & Discussion] cmrntnnr:
I am still happily running magisk v23 and passing safetynet. One way to do what you want is as follows:

-Download the older magisk versions as a zips for uninstall and install.

-Boot to twrp.

-Install the Magisk uninstall zip

-Reboot back to twrp

-Install the zip for the older magisk.

-Reboot phone

-Open the Magisk app, turn off updates.

-Let Magisk do what it needs and reboot

Glad the OP worked. The V35 on A10 is still a great phone.
[LG V35 Guides, News, & Discussion] rpgdev:
By older versions you mean v23? v23 doesn't have an uninstaller script it's all unified now, would that work? What about uninstalling magisk from the manager app? I'm trying to avoid getting my data wiped while downgrading magisk on the LGv35.
[LG V35 Guides, News, & Discussion] rpgdev:
Thank you @cmrntnnr, I managed to downgrade but doing it via twrp was buggy and didn't quite work. I ended up patching boot_a using magisk 23 and doing it everything all over again. I'm attaching it here for anyone interested. Just use it instead of the one posted by @johnbrady93 and should be fine.
[LG V35 Guides, News, & Discussion] rpgdev:
I need help guys. I was trying to do this procedure again on the same phone. Flashed the Korean Q again and everything went fine until I hit the step: reboot the phone using vol- + power after flashing the engabl.bin. For some reason it gave me problems to reboot the phone but once it did it entered the "any key to shutdown" fastboot loop and I don't seem to be able to get out of it. I tried flashing the rom again using lgup but lgup doesn't recognize the phone in this state. It seems like I'm able to enter EDL mode but qfil can't read the partitions. It gives me a sahara fail error.

Both lgup and qfil worked just fine to read the partitions before I flashed the engabl.bin not sure what happened. Hopefully this state is reversible and not fully bricked :'(
[LG V35 Guides, News, & Discussion] cmrntnnr:
I doubt it is bricked. That said, I'm not sure what you have or to suggest. I had Sahara when first getting qfil going on on my laptop. It seems pretty finicky about cable, connection quality, and drivers. Has you gear changed? You may get a larger audience to help on the telegram channel.
[LG V35 Guides, News, & Discussion] rpgdev:
Turns out I needed to restart Windows, apparently it installed some updates in the middle of me doin this (I just use windows for these android rom related stuff). After that qfil worked as expected. One issue I'm encountering though is that the twrp module installation removes my root, doesn't matter how many times I do it, any reason why?
[LG V35 Guides, News, & Discussion] cmrntnnr:
Glad it was an easy fix. Understand about the OS. I use a 2010 era laptop that has USB 2.0 ports and W7 for phone flashing. It never sees the internet nor is used for anything else.

Twrp is a bit complicated. Follow clouds's localization instructions to the letter and you should be good.
