Hi guys, thinking of picking up a V20. Been looking at Chinese phones but keep coming back to the V20. My only concern with it is the carrier check to toggle mobile hotspot. Seems I would need to root to bypass that, and the last phone I rooted was a Note 2 back in the day. I would be using it on cricket, so an AT&T (910) or unlocked (996) variant would be my choice I believe. Anyone give any suggestions or work around besides rooting to get the mobile hotspot to work?

I suggest if you want to root I'd go with the 996, because unless the security patch is 12/16 or earlier you won't be able to root the 910, no kdz available to roll back.
@cnjax While it is true that no KDZ is available for the H910, the H915 KDZ works just fine. The H910 is rootable on the latest (v10t) firmware: link.

Thanks guys, I've found a local person selling a US996 for $200. Gonna go check it out and make sure it looks good. If I get it i'll look into rooting it. So the 996 doesn't matter what security patch it is on correct?

My mistake, based on what I read in the dirty santa thread. Glad you found a work around for later versions.

So I'm looking to get a used T-Mobile or AT&T unlocked. I use Straight Talk AT&T right now and may consider jumping to T-Mobile Straight Talk.
Of these 2 devices, which is best for custom ROMS, root access, etc etc? The H918 is bootloader unlocked right, so should that one be better? Or are they equal nowadays?
If the person you buy the H918 from has upgraded to the latest firmware (v10p or v10q -- you need v10k or lower), you can't root it, but the H910 can be rooted on the latest firmware as of today (v10p).
Because AT&T only does encrypted OTA updates, they don't really have a reason to increment ARB, so unless they have some engineer that reads XDA and decides to let the higher ups know that they should increment ARB, the phone will continue to be rootable for the foreseeable future.
-- Brian
Thanks for the info. I'll likely get the AT&T one. If I do get the H910 then and I switch to a T-Mobile SIM, would wifi calling/sms work?
I use an H910 on T-Mobile and everything works just fine.

Hey! I'm planning on buying LG v20 too because of LG G5 warranty void ---> corrosion on the main board and price estimate it to get it fixed is 160€.. Lol and it's not even the main problem. There cough*severe LCD screen burn* cough cough and another problem is the GAP at the bottom that maybe is the reason for corrosion.
I was planning on buying h918 because it is 20€ cheaper on EBay but if it is updated to the latest firmware would I be screwed? So would it be safer to just buy h910 for the sake of rooting? Thanks

@raven213 I am running stock v10m that I debloated and tweaked. Don't want to hijack his thread, so if you want to open a thread on wifi calling, I can hopefully help you out.

Is it possible to safely flash a us996 unlocked rom onto my ls997zvc? And will it allow me to continue to use my gsm att based sim card? I bought this phone used the other day. He said it was Verizon unlocked but turns out its this sprint model. No carrier branding anywhere. No splash screen on boot. I almost thought it was a non carrier based unlocked phone until i looked up the model number.
Bump
Buuuuuump. I bought my phone through sprint, paid it off, they keep telling me It's unlocked, but i have to factory reset every time i turn my phone off to get it to work with the other carrier sim. I've contacted them over and over and all they say is "we sent the unlock signal, that's all we can do on our end" but their signal is only working on factory reset. I really want to root this and install the unlocked firmware so i can have my phone without having to reinstall everything constantly. I mistakenly upgraded to ZVC update before having it unlocked and now I'm stuck. Any updates on an unlock eta?
Unfortunately I believe that ZVC is ARB 2 and it has the latest lafd with copy2 pulled, so that means that even once the lafsploit is finished, the LS997 will not be able to use it because you can't roll back to a firmware version that has copy2. If I am wrong, and ZVC is still ARB 1, then you can roll back to a version that has copy2.
If I can find a dump of the ZVC firmware, I can tell you for certain what ARB version it is. If no one has made a dump, you can do it yourself by grabbing the patched LG UP, and used the dump option. If you grab one of the full stock flashable zips from another model, you can see what partitions need to be included. I could just tell you, but I think people need to learn
-- Brian
I accidentally updated mine to zvd the other day. A brand new release. Would be very nice if you could tell me exactly how to flash the us996 firware safely. Ther3 has to be a way to unlock this damned phone. I paid 200 for it and now i am ****ed.
Please help me out. I could post a dump of the zvd firmware if i can figure it out

@me2151 Welcome back dude
If all goes as planned, we will soon be able to root any model on any ARB version. My info above about ARB 2 being an issue was incorrect (must have been on crack when I typed that post).
LG phones with unlockable bootloaders (or that have an engineering aboot / abl) will be rootable indefinitely -- a hole that can't be closed without changing their security significantly.

Please keep me informed on your progress. I really just want to do this to gsm unlock my phone for my at&t sim card. Guy sold me it saying it was unlocked already.
Do i have to root to flash us996 rom onto my phone? And does that unlock it or the root method from dirty santa exploit what uicc unlocks the phone. I read tidbits of information on this forum that say the phone is uicc unlocked after rooting and/or flashing us996 firmware, but all are supposedly only possible on zv7 or older firmware of Sprint phones.

Hello, I'm here with Ls997 ZVA, ARB=1 and are waiting for any update from you guys.
Thank you ^^
Does anybody know If i can do the similar thing but towards using TMobile network?? Can I flash Tmo H918 stock rom to LS997 Sprint variant?? I just want to use my Tmo Sim, or maybe if my LS997-SVC still a problem?

2 years late but better than never I suppose?
No idea what my LS997 is using. Performed the dirty santa a long time ago to root, and just this morning I flashed /e/OS over Lineage to test the waters with a de-googled experience. I'm now on T-mobile magenta max plan following the merge and daily driver is a Pixel 4A 5G. Popped the SIM into the V20 running /e/OS and data works but voice and text do not. Not sure if this is a hardware, firmware, or software incompatibility.
Honestly the V20 really pissed me off with how locked down it was. I am NEVER buying a phone that is not easy to root or repair. that is 100% deal breaking for me. Pixel phones have unlockable bootloaders so not too much bull**** necessary to break from the clutches of these damn phone companies and carriers.
Hi.
I am expecting delivery of an LG V20 h910 from eBay in the coming days, but don't have an AT&T SIM (EU user).
Is there a way to flash an unlocked, stock version of the software (eg US996) so I can update the phone to the latest version?
I heard non-AT&T SIM users don't get updates thru AT&T, so wondering how I can get the latest software for it.
I would prefer not to root the phone, but would do if necessary (and if I can then get a fully functional, up-to-date software version).
Thanks in advance.

First off, if its not sim unlocked phone, it will forever stay sim locked unless you get the network unlock for it. EVEN if you flash any of the other brand roms. Also, AT&T doesn't have the full stock kdz to revert to, there are work arounds to return to stock. This phone has trouble with the screen ghosting/retention, as well as bonkers HDR camera performance, also not to forget, GPS inaccuracy upto 50 meters. I'd suggest look away from LG unless you're going for LG v30 which doesn't carry any of these issues.
If you have already bought, paid and "expecting" shipment anytime soon, you should make sure that its network unlocked H910. (make backup of your partitions before flashing any other brand rom because you will need modem, modemst1, modemst2 and misc partitions in-case you lose the signals). Then you can easily flash it with H915 rom which is the best among debloated stock roms. Flash H910 v10m firmware over it, then flash the modem/modemst1/modemst2/misc files from fastboot to get network signal. From there on forward, you may keep H915 rom with H910 v10m base, or you can even move on to lineage roms. I'd suggest stay rooted with manual color calibration for no-ghosting measures.

You can't flash another variant rom until you unlock the bootloader and root. As far as functionality with the 996 will depend on the bands your carrier supports
Sent from my LG-H910 using XDA Labs
I received my used AT&T V20 yesterday also bought from eBay. I'm on O2 and it works fine. Just be sure your phone is network unlocked. Only thing is the bloatware.
So much misinformation in this thread, but I will just address the original question....
Yes, you can flash the US996 KDZ without rooting .. just flash like you would any other KDZ. You lose some AT&T specific features while running US996, but if you are overseas, I don't think that will bother you.
As far as I know, that will SIM unlock the phone if it is locked. If it doesn't, then the engineering bootloader that you use to root will SIM unlock the phone as well as bootloader unlock it.
So, first try the US996 KDZ, if that doesn't SIM unlock, you will have to root.

The phone should come pre-unlocked for all networks. I'm mainly concerned about system updates. US996 sounds good, as I can't use AT&T here (AT&T doesn't exist in my country). Would I be able to update the firmware in any way once US996 KDZ is installed? Thanks in advance.

No system updates. Had the latest update with the latest security patch, but I downgraded because I want to root it. Still 7.0, but with a earlier patch level.
I do believe that because LG is not going to update the us996 to Oreo now a lot of themes being developed no longer work on this device any suggestions on where to go from here tried to unlock bootloader with no success......
Many have been successful in unlocking/rooting the US996, and there are a few discussions on XDA on how to do that.
My question is what the new date is for the Oreo update. I've heard mid-Nov and late-Nov. Does anyone know?
With only a couple of days left in November it is not looking good for the v20
Do we have any more information on updates?
Kinda a bummer when you buy the US996 thinking that the "carrier unlocked" status would make it get updates from LG quicker than carriers update the phones.

Not for me here
Got the notice this morning......took 20f. It had a little more battery this evening than on Nougat. No SIM though; gotta swap devices in VZ account due to unlocked Note 3 using Micro SIM.
Good timing; was getting very frustrated with losing signal/sim on Note 3 custom roms. May camp out on the V20 for a while and see how it improves things.
I've been trying to get 20f on my (supposedly) unlocked US996 phone.
Originally tried downloading OTA, but got Invalid Software Package twice.
My wifi is capped at 30gb/mo(!), and it forces me to use wifi - no option to use LTE, and I have unlimited (22gb) of it.
So I decided to try LG Bridge.
It downloaded & started applying the update, only to say "Your phone cannot update". I tried it a few times. Same thing @ same spot.
Then I decided to try LGUP. See error here:
https://www.reddit.com/r/lgv20/comments/ady77a/help_upgrading_from_us99610n_to_us99620f/
(I've downloaded the TWRP img for v20 linked, but the kdz file linked has a note: * - unlocked non-US Cellular)
Now I can't get into my phone. It just brings up the Firmware Update screen.
When I checked using fastboot, it says it is not unlocked. Is that because of the SIM card?
Is there anyway to restore the existing(?) 10n firmware? Can I flash anything (TWRP, etc) without it being unlocked? And if not, do I need to call US Cellular to get it unlocked?
I'm quite rusty with custom roms & the like. It's been awhile!
--- EDIT ---
I was able to get 10n (what I had before this mishap) reinstalled with no errors, using LGUP.
https://lg-firmwares.com/lg-us996-firmwares/
I lost some pictures that weren't on my SD card, but I'm trying to restore a Google backup now.
Hopefully this will be helpful for someone else!
Have had Oreo update now for a couple of days and it is running smoothly.......never thought it would get here........
Bought a H871 cheap on eBay and it worked awesome at first..then i got the software update notification to upgrade to Oreo. Thats when it all went downhill. The phone is just a laggy mess now ive deleted the cache and factory reset the phone so many times I lost count now. Nothing has made it any better. Then i get the update to go to pie and its the same story. I've factory reset and deleted cache so many times with no improvement. So my question is how can i go back to stock 7.0. Where all was right in the world. I saw you can use LGUP but I cant find a h871 kdz to flash....thanks for any help that can be provided
www.lg-firmwares.com
Here you can easily find the nougat 7 but my question is that can you downgrade your phone to nougat from pie without unlocking your phones bootloader.....?
the phone is probably damaged internally causing the processor to run slower to keep itself from overheating? no way to downgrade as the at&t firmware files have never leaked nor been made public. best bet is to follow a flash guide to load up oreo from US997 device.
see this guide -->> https://forum.xda-developers.com/att-g6/how-to/convert-upgrade-att-g6-to-h873-oreo-t3791848
please note this firmware will work on AT&T network however you will lose the ability to revert back to AT&T firmware. You will also not be able to use AT&T wifi calling

This is a great question. I believe some users have successfully tried it with Oreo. I tried unsuccessfully with my AT&T H871 but it is currently on pie. I have asked this question for my situation, but so far I have not received an answer. Head on over to the thread referenced above for conversion. You may need to read many pages of posts, but there are some who have tried this with Oreo and may have suggestions for you.
I have an AT&T LG G6 H871 that has been updated to Pie, and I was looking for a way to flash it so it would no longer have AT&T firmware. I live in Canada, in a rural area, so it would be great if I was able to switch the Network Mode to LTE( it favors HSPA signal at the moment) and get rid of the AT&T bloatware. I have tried using LGUP to flash this thing following the steps laid out in various forums, but I can't get it to work. Any help would be appreciated!
