Is there a way to downgrade from 7.0 to 6.0 even though out the box the V20 comes running 7.0?

1. The v20 doesn't have 6.0 Firmware
2. If it did have it and you were on 7.0 Firmware then downgrading would actually brick your device.
Why? Because LG incorporated an "Anti_Rollback" counter. You can see it in the 'Hidden Menu'.
i.e. If MM was Anti-Rollback #1 and Nougat Anti-Rollback was #2 there would be no going back. You can only flash/upgrade/restore firmware/Roms with the same Anti-Rollback number. So if you take an OTA and it switches to 3 then any Roms or Backups or even Firmware Packages that are lesser than that you can No longer use.
Good Luck.

Thanks, that summed it up for me [emoji106] [emoji106]

I just bought a v20 off eBay. It was already on h91810r version I just bumped it back to h91810p which is 2 versions back with no issue and got to h91810k and it rejected it so I guess that's that. No root or custom recovery for me. Lg played us dirty.

10k is the last version with ARB=0 (anti-rollback). Any firmware update that followed was ARB=1.
If you buy a V20 off of eBay, your best bet is to not buy it from an individual because they will probably have used it right up until the time of auction, meaning they will probably have installed the latest updates. Mobile phone resellers that sell them in lots are a better bet.
I got mine last week and it was on 10j. You bet I made sure it was not going to be connected to the Internet before I was done rooting.

For what it's worth. I think the anti rollback thing is mainly T-Mobiles fault since I believe the T-Mobile model is the only one that has anti rollback activated on it.

I tried getting it to h918k but it failed. And I did buy it from a seller not a everyday Joe. That's why I was pissed when I seen it was h91810r I was like WTF I'll brick it and send it back.

Unfortunately, it's still a luck of the draw. A mobile phone reseller might have gone ahead and put the latest updates on it, but that's not always the case. If an individual is selling their V20, they probably didn't keep it locked away for the last year before deciding now is a good time to sell it.
Anyway, you should keep a watch on this thread. There is hope, but it won't be instant gratification.

Yah I figured in the near future it would see full root and full working twrp. The bottom line is I like the damn phone, it works perfectly ( for a LG ) it's a big step up from the v10. But the power button if faulty you have to just about put your finger through the phone to get it to activate and that's a pain in the ass when your doing the combo to get into DL mode or fastboot.

Then the power button alone issue would be good enough reason to get a return or exchange.

Unfortunately the seller has about 20 of these devices mainly all t mobile but there all messed up or in terrible condition. I paid 130$ for this and it's mint except that button. He's got a 90$ parts phone that's unlocked but has a botched charger port and I bet it's sitting on h91810j or older firmware. There's root in sight.

AT&T K10 receiving update

So at the time of this post, my phone is currently downloading a 1215.98 MB update. Comsidering my last update was only 300 MB, I assume this is nougat. My phone is a k425. I'LL report back once the download is done (which might be a bit; all this weather is killing our internet)

And here's a screenshot for those who are skeptical.

Well the updates almost done; ill report back once I've installed it

Nougat is out for the k425

Wow. We are waiting for all other models too.

I can also confirm this but with one issue if you use the att go phone version you will not be able to update for a few days as there putting priority on people that have this phone and are under contract. You can work around this by finding a friend and use his sim card as long as there a contract att member to get the update on your phone then switch back after the update. This is only for a few days as the people that are under contract get it first. Sigh

The update is only for t moile and att variants; it seems like they basically paid lg to have them help build this update, so people continue to buy this phone, and not waste so much money on lost sales.

Anyone on MetroPCS get this update?

LG K10 T-MOBILE GOT NOUGAT!

Wow! Thanks! Just checked my phone and got the update.

It's really good news for lg k10 user, But When we will receive nougat update for k10 430dsy?

Dude, seriously? About 5 out of your 15 posts are asking about nougat for k430dsy, and 5 about rooting it, stop spamming.
Nobody here knows when or even will k430dsy get nougat, because LG won't say anything.

MetroPCS got it, too.

Battery life is notebly worse after install; after clearing cache about a week or two after install helped it improve

woot
AT&T your update process really bad finally after a month and a half They really need to stop all this release in batches crap with updating it easy just allow people with a valid sim to download the update. No if we can just root lg-k425 and nougat be great. Any one know of a easy way to copy the firmware with out root?

US997 oreo OTA out now.

Could someone please capture a kdz for all of us here?

Saw that this morning too. Deciding if I want to upgrade now. Probably will wait a bit given the less than stellar reports other users are giving on other models.

I'm going to wait as well. I don't have any issue with Android 7.0 on my US997. My average battery usage is 85 hours. I use the phone daily for calls, texts, emails, calendar & alarms, notes, camera, news, chess, fm radio, and mp3. Other apps like youtube, redbull tv, gps, etc. get used on a weekly basis only.

it's lit

Also waiting for the kdz...

I am updating as I type this, excuse my ignorance, what is a kdz?

Can someone on US997 oreo type *#546368#*997# in the dialer and let me know what your ARB version is? It'll look like so.

KDZ is the format which LG uses when posting official firmware releases on their website. KDZ are all stock releases from LG. Custom ROMs do not come as KDZ, the tend to come as ZIP file.

Once it is downloaded, where is the kdz file located so that I can share it?

Look at this article, it explains how to get the KDZ from using LG bridge on a computer.

It's weird it looks like LG bridge wants to update my phone, but i keep getting a server error. I have the US Cellular variant, and i think thats the issue.

Thanks for all your efforts guys, truly appreciate it.

FINALLY!!!!!!! Here we go!!

Not yet, I used LG UP to get my phone up to 17a from 16c. Still no notification.

I used LG Bridge to take the update for 20b on Friday night and I copied out the KDZ when it was finished downloading. I can upload/share it but I'm not sure how to do it here on XDA. All I've got is google drive and I'm not terribly eager to post a link to a file on my personal-use drive.

LG V20 T Mobile Mobile Data Not Working after Update

Hi Please help me, i upgraded my OS to Oreo, and after that, i can recieve calls and messages but when im turning on my mobile data, it doesnt work. My APN is correct, any help
Thanks

And when did T-Mobile release Oreo for the H918?
From their support site:
Software version: Android 8.0 Oreo
Phase: Manufacturer Development
T-Mobile and the device manufacturer have agreed to support a new software update. The manufacturer is working on it.

If you have a rooted phone, and you installed boot and system from one of the models that currently does have Oreo, no -- your modem isn't going to work with their rild.

Maybe he means lineage?? The lineage build is Oreo right?

Could be, but that would make diagnosing the problem much easier if he would have said Lineage
If that is the case, I hope the OP made a backup of their EFS....

Hi Brian...
I got my H918, Used your FWUL and LAFsploit.... (I think you are like a V20 rockstar...? thank gosh there's guys like you and websites like XDA to find you with!)
Got superV20 V2.1 on, I installed with
the option or the MK2000 kernel, although, I'm listed as kernel version 3.18.31. My softwaRe is 10t security patcheck level, March 1st, 2018.
In the last 2 days TMOBILE has been trying to push an Android System Update, of around 119.8 Mb to my phone.
(I don't know that it matters or is even noteworthy, but my provider is Virgin Mobile Canada, In B.C..)
It's asking for restart before installing, and I just keep closing it.
Could this be Oreo?

Looking for an explanation of Cross Flashing results from AT&T to Fi version

Hi, so I flashed my AT&T V35 to the Google Fi variant since I am in Canada and cannot get any AT&T updates ever.
The flash went over just fine but when I checked my phone's 'about' settings I noticed that the Software Version still says V350AWM10h instead of the Fi variant which is LMV350ULM. The flash process in LGUP said successful so shouldn't the software version on the phone reflect that?
Thanks

So the Security patch level will change but the Software version is tied to the HW ID of the device and will remain as such?

Basically, once you cross-flash, you will not be getting OTA updates for the ULM software. You'd have to manually update your phone. Let's just say that from a bootloader perspective, you still have the AWM device even though you are able to run ULM software.

Interesting. This is completely different from crossflashing the North American LG V30 variants: US998, AT&T H931, Canada H933, Verizon VS996, regional carrier AS998, Sprint LS998.
Cross flashing those completely converts those variants to whatever firmware you are flashing. No, you won't get OTA updates -- but it gives you those bands and also reflects the firmware version, etc in About Phone. Many people cross flash H931 AT&T to carrier unlocked variants and it becomes that phone. Cross flashing to US998 also gives you fastboot flash commands -- but for H931 takes away a couple of the minor AT&T LTE bands while adding others and even adding CDMA bands. About Phone will show you that you have US998 with the correct version firmware you flashed.
So, strange it's different with the V35.
