Maybe we will see unofficial unlock on all carrier devices soon
But what means "v0"? Where can I see whether my phone is "v0"?
Edit: Link to LGVIET Forum thread:
http://lgviet.com/forum/threads/twp...t-lg-f500l-lg-f500k-lg-f500s-by-lgviet.48299/
great news... but yah what's v0???

So we will see the twrp bump for all the g4 versions? WAAAOW
V0 has to do with the anti rollback flag that newer firmwares install. A newer firmware will change v0 to v1 or v2 etc. Flashing older firmware will make the phone very unhappy. It's why, on several US based phones, trying to downgrade will brick the phone COMPLETELY. Search for my PSA thread.
As far as I know this does not affect H815 international or am I wrong?

V0 is the shipped firmware that your device came with, at least it is with Verizon. I think the firmware version (for Verizon) is 10b. I've stayed on it this whole time so I'm hoping it pays off.
The guy that originally posted about the bootloader unlock has been really quiet though. I hope he plans to release.
Looks like I have a bit to wait. I checked it in your PSA thread before not knowing what it meant but now I do. I'm on v2. :/
For the most part I'm probably better off waiting for that official bootloader unlock if it should ever come.
Trying not to think of D3. v1.1 here, rooted, bloat gone, Google sms & keyboard, ota nutered, Tether & Mobil hotspot mod. G2 was so fast it tripped over itself. G4 with 8 cores? we are moving forward. Fingers crossed on bootloader unlock.
Is it worth unlocking now that marshmallow is not that far from coming up in our devices?
How to check bootloader
How do i check my boatloader version
Will 11a work or should I just go ahead and sell this crap before my disappointment arrives?
You can checked by looking at this thread

if you have a USA G4 and ever took an OTA update (forced or manual) then you are not on v0.
11a was an OTA update.
For those asking what version they're on... see this post http://forum.xda-developers.com/showpost.php?p=62842317&postcount=16
notice the antirollback option at the very bottom. don't have that option? then you can't check with that menu.
If you ever flashed a KDZ to a USA G4.. then you are no you are not at v0. All USA KDZ's are at least v1.
95% of all the USA G4 users are at v1 or higher. Unless you went out of your way to block OTA updates on the device within the first few weeks of releases.. it's probably already taken an update or two.
If you have a non-USA G4 then you are on v0.

Hi Autoprime,
Attached is my screenshot of AT&T LG G4 H810 running 10g and rooted. It says the Sub S/W version is 0....does that indicate the anti-rollback feature is NOT enabled, i.e., I might be on v0 and therefore unlock my bootloader?

I bought Verizon G4 last week and it came with 11a.
So I guess it was forced before I bought it. If I'm reading correctly, I would not be able to unlock the boot loader. Correct?

correct, at least a bootloader unlock method made for v0 devices. v1+ isn't impossible... but less likely someone will post an exploit for those devices any time soon.

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.

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.
As the title says, can this be saved from 10P update? If you watch the top, you will see 10P is schedule for update.
What I want is to improve V20 performance, audio and battery performance. On older phones like Notes and Galaxy, I used to root them and improve them on most area's.
Sadly the V20 is a pain as far I have read.
Thanks in advance.
What model v20 is that?

T Mobile
I think 10k is unrootable but if im correct you could downgrade on 10k to 10d to root.
10k is rootable with dirtycow, but you can downgrade to 10d as raven213 said, and then you can use fastboot flash recovery.
As for not taking the update, your safest bet is to backup your phone and then pull the battery and immediately get into download mode so you can flash a KDZ, because if your phone reboots, that update will be applied and there is no rooting 10p right now.
EDIT: actually, you could just root now. Once you have TWRP on, you may get stuck on a loop until you wipe part of the misc partition, but at least it won't apply.
EDIT2: Sorry, 10k isn't rootable, you will need to roll back to at least 10j.

Planning on swapping 918 V20 for another 918 V20 using Jump. Currently suffering a broken screen. What are the odds the replacement V20 in store is on a rootable firmware? Or do they even swap out in store?
And apologies for apparent thread hijack.

I just picked up a t-mobile v20 last week and it was manufactured in August with the 10p firmware. I think chances of finding an older firmware model would be hard. Here's hoping for a root method soon.
Hmmm

Yeah, not the news I was hoping for. I may have them pull a box and boot it up. If its an older firmware then I will grab it. Otherwise, I may just make the move to the V30. But not terribly excited about starting a new EIP.
What is the latest rootable firmware?
Appreciate the info.
10j is the last rootable, but 10k is ARB 0 so you can roll back. 10p and 10q are ARB 1 and not rootable.

<~~~ on 10q :crying:
Woohoo! Just got my new V20 and it's on 10K!
The one I purchased in store a month or so ago came with 10j. It even said so on the outside of the box on the printed label. If you're buying new, it's something you can easily check. I just had them leave it sealed up and waited to power up till I was ready to root it.
Can anyone point to a guide/thread for detailed instructions on rolling back the LG V20 918 running 10k... and then rooting?
Been searching for quite awhile and found many references, but no walkthrough guides.

Is there a way to go back to stock? I'm on 10p bootloader+modem/TWRP, don't care about root. Can I just flash the 10p/10q KDZ or TOT file?
@MidtownHD If you don't care about root, then yes, flash the 10p or 10q KDZ and you will be back 100% stock.

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.
Hey guys, I just bought a a vs995 from ebay new in box hoping it would come in nougat so I could root. But it came stock with 8.0.0
and a security patch date of 10-1-2018. Software version of 20C. Any way to downgrade or root this thing? Thanks for any recommendations.

Reread them again. They're downgrading in order to root (mostly), not with root.
But the TLDR of those guides is LG UP, in upgrade mode, with whatever firmware (kdz).
Anyway here's a link to the vs995 thread where the guy made videos and has links to lgup and one of the old firmware that can be used to root. If you want to browse or download a different one this site is ok but slowish
