Hello everyone! I need the help of this community to try to overcome a doubt that plagues me.
I am a happy user of a LG V20 from VERIZON, however I am using it in Portugal. The only problem I found was the lack of APN, which I solved with the manual configuration. With regular use, I noticed that this equipment has a great deficit in network capture.
This way I ask for your help here. My equipment being a VERIZON equipment, VS995.
Can I install a ROM from other devices? Namely H990DS, H918, H910, US996, LS997.
If so, what guarantees better network coverage? Which one has the least trash from the operator?
I run the risk of having the phone locked if I change ROM?
Thanks and see you all soon.
I can only tell you that if you flash the H918 firmware, you will brick your phone. The H999DS just won't work. The others .. flash then and try. Make sure what you flash is ARB 0 since the VS995 is still ARB 0, and if what you flash doesn't work, you need to be able to flash the VS995 KDZ back .. can't do that if you have flashed firmware with a higher ARB.

I need Band 66 (LTE) with my Canadian provider (Freedom Mobile). Both the H918 (T-Mobile) and the H915 (Freedom Mobile) have Band 66. With my new unlocked LG V20 (T-Mobile) version running on my Canadian Freedom Mobile LTE version, all works well, with the exception of no LTE. I have done many searches and come up confused as to which way to do this. Can I use just LG UP and flash the H915 firmware over the H918 and expect all to be well with working LTE on my LG V20? Has LG Flash Tool been replaced with a newer LGUP? I'm just spinning in a forest of confusion here. Any direction would be appreciated. Thx
Wow..... 3 days have passed and no answers to my question. Have I stumped the experts?

It is never recommended to flash a firmware not meant to be for your phone. Chances are that you will brick your phone if you do. Probably that's why no one is answering because it has been said many times in different ways. And almost no one likes to be the guinea pig. Nevertheless, if you do try it with LG UP, let everybody know about your results :good:
The H918 doesn't support as many frequencies as the H910 / H915 (the H910 and H915 are the exact same phone). That could be a limitation of the radio firmware, and if it doesn't soft brick your phone, could be fixed by flashing the H915 KDZ.
Now the good news there is a KDZ for the H918, so, if you soft brick your phone -- viola -- flash the H918 KDZ and you are back to where you are.
Just a heads up though, download mode is *ALMOST* impossible to blow up, but almost is not the same as impossible. I personally have never managed to destroy download mode on an LG phone (and I have deliberately tried on several older phones - G2, G3, G4, just to see if I could recover if it happened).
However, that isn't to say that it is completely impossible (the dreaded 9008 error). Example for LG G3: https://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
But, as you can see, even that can be fixed as long as you: 1 - have a KDZ, 2 - are willing to tear apart your phone.
Please post your results if you decide to go through with it

The only LG Phone that I own and remember was The E980 Optimus G Pro “the unbrickable” and thanks to att to ruin a outstanding phone simply not get the promo and the attention of the same sh** of Samsung S4 for this time.
After 2 months passing from my original post, I'm still at the end of a dark tunnel...... and no BAND 66 working on my T-Mobile H918 running on the Canadian carrier........... Freedom Mobile . Has anybody had any success running a TM (H918) on Freedom Mobile and get LTE (Band 66)?
You can't since the kdz for freedom mobile is not out yet

I have been looking at the FCC documents, and I seems H918 is the same hardware as the H910PR.
You can also see there that H910 and H915 are the same, as mentioned above.
I would not try to cross-flash firmware from different phones at least, if I where to do it at all.
Edit: The H918 has a unique oem configured key in the qfprom. Meaning flashing any bootloader not specific to the H918 will hard-brick your phone, at this point that is equivalent to a completely broken and useless phone.
if we can get the KDZ file maybe can get the modem
Any luck on this in the past month, or same situation still?
Freedom have had band 66 allowed to be used only on handsets sold by them, probably by white listing IMEIs. Now that they have iPhone, this might change, but my knowledge is limited.
Anybody know if I can lgup uppercut flash the H918 stock Rom to the Sprint LS997ZVC??? I have read a comment that I found saying something that LS997ZVC is ARB1 and if I'm gonna flash a room to it, it has to have an equivalent ARB1 rom?. I order a TMobile variant LG V20 from Amazon and they freaking sent me a Sprint Variant.... I took the phone to Sprint and they said the device is network unlocked but when I try TMobile Sim with the correct Tmo APN(fast.tmobile.com blah blah) in the phone it doesn't even work. TMobile even says the phone should be able to work on their network but it's "up to Sprint".... WTH... I have read the US996 to LS997 thread but the guy had no signal ability at all after flashing due to that the us996 flashed into the wrong partitions. I even tried eBay for a network unlock code but they say the phone is already unlocked.. WTH man.
Can someone help and guide me through this?
No, you can't flash the H918 KDZ onto your phone. The RSA key in the CPU is different -- you will have a 9008 brick.
Your phone doesn't work on T-Mobile's network because Sprint is run by a bunch of assholes and they deliberately lockout the bands that you need via the modem firmware. Since your phone is ARB 1, you can't root it currently to fix it.
Sorry -- return it to Amazon if they sent you the wrong phone.

AH BUMMER!. Oh well, İ appreciate you taking your time to reply bro. Thanks
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

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.
Hello all,
I'm really new to the phone modification scene. I tinker around with computers mostly. I have an unlocked sprint version of the LG v20, the only problem is I am not receiving data on my new carrier (even with the correct apn added). I'm pretty sure this is a firmware issue. I was wondering if there was a way to flash the us996 or verizon version of the phone to get data to work. I know the sprint version is super locked down. I just didn't know if using a modded version of LGUP and the us996 kdz would brick the phone or not, or if there was a way to flash different firmware on the version I am on.
Thanks and cheers,,

Your firmware has anti-rollback enabled (ARB1), and the US996 and VS995 do not (ARB0), so flashing any KDZ (Sprint does not provide KDZ files at all) will surely brick your phone permanently. You're pretty much stuck with the Sprint firmware you currently have, and the only change possible is taking an official over-the-air update to Oreo, but that could re-lock the phone to Sprint only again.
If you're getting into phone modification, then you'll be much better off with any other LG V20 variant as they are all rootable, unlike the Sprint model with ARB1.

That really sucks, yeah I don't really want to try and hassle with sprint customer support, I got the phone second-hand from my step-brother. So, i'm not sure if they would even unlock it again for me. Thanks for the information. I wasn't sure if there was a way to flash certain parts of the software to possible fix the modem issues or not.
So I picked up this old flagship budget phone and I was having no service at all. I tried resetting the phone, and reconfiguring APN settings, scanning for networks, but nothing worked.
So I did some research, and it turns out I was told I was getting the US996 (factory unlocked) version which is compatible with all carriers. But when I look under the battery, it says LS997 instead. But when I look at the software settings, it says Software Version US99610p. The seller must have flashed the US996 firmware onto an LS997 (Sprint) phone.
So at this point, I'm pretty sure I got scammed, and the sad part is this phone isn't refundable. I thought maybe if I could somehow get this phone off the US996 firmware and back to the LS997 firmware it originally came with, I'd have no problems. My carrier is Sprint as well.
But the sad part is, there's no LS997 KDZ's which I could just flash, since Sprint, unlike other carriers, does not release KDZ's.
So at this point, what are my options? Any help will be greatly appreciated.
Not sure if this is of much help, but if I were you I would unlock the bootloader and just flash a custom rom.

I thought of that, but should I use the LS997 method or the US996 method to unlock?
Honestly Im not too sure since I have a H918 and none of those, Take my info with a grain of salt as I might be wrong, I think that the firmware update partition is not a part of the OS so you may be able to get away using the LS997 method?
