How to know which bands my LS998 turned into a US998 has? - LG V30 Questions & Answers

I bought it off ebay last year and I do remember looking up the serial and finding out it was originally from sprint.
I use it on Cricket which uses the majority of AT&T's bands, however I feel that signal is always low almost everywhere I go and I am wondering if the signal is simply worst due to missing certain bands.
Cricket LTE uses B2/B4/B17(B12)/B30
Does the flashed version have all of those bands?
Thanks!

That helps, thanks!
I see I am only missing band30.
Wonder how much of a difference that would make around Atlanta, which is a shame because otherwise this is an excellent phone!

I'm in Atlanta, I use AT&T Prepaid and I don't lose anything by not having band 30.
Besides, Cricket speed is capped by owner AT&T at 8mbps, and even 3mbps for some plans. From Cricket website:
Cricket caps download speeds on all its rate plans at 8Mbps (LTE)/4Mbps (4G) except for the Unlimited Plan which is capped at 3 Mbps (LTE/4G) and the Unlimited Extra Plan and data only plans.

Screenshot below isn't even the fastest speed I've gotten, it's just the one I could easily find right now.

My main problem has been more about how many bars I am getting rather than the actual speed, which is just fine for my uses.
Since I am a Field Technician and travel outside Atlanta often, I get to experience this a bit more often, so it would depend if band 30 covers areas outside Atlanta better.
Just gonna have to suck it up for now lol

Real US998 supports all those bands... I'm not sure about LS998 converted to US998 since LS998 originally doesn't support band 30...

Uh, no it doesn't. I quoted the US998 bands from the LG website. See attached screenshot. Band 30 is not listed while all those other bands are.
US998
CDMA: 800 MHz CDMA
2G GSM: 850/900/1800/1900 MHz
3G UMTS (HSPA):850/900/1900/2100 MHz
4G LTE Bands: 1/2/3/4/5/7/12/13/(17)/20/25/66
(There's a reason LTE band 17 is in parenthesis, but I've explained it before and don't feel like going into it right now. Short answer, it's there as part of LTE band 12.)
Now the Canada H933 has LTE band 30 and also AT&T H931. The US998 is the official North American carrier unlocked variant, but it doesn't support ALL the minor bands of ALL the carriers.
* It's missing LTE band 71 (while the T-mobile H932 has that),
* it's missing a couple of Sprint bands (which LS998 has, of course), and
* it's missing both LTE band 29 and 30, which AT&T use (and which the H931 have).
Just because it's in the Hidden Menu doesn't mean it's supported. LTE band 71 is also in the US998 hidden menu, but you can't actually receive it.
I have an "original" US998, I run LTE Discovery app often, I live in Atlanta, and there's no LTE band 30 in any of my logs -- because US998 doesn't support it.

Cross flashed to Frankenstein it becomes a full US998 with US998 modems. That is the difference in the North American V30 variants. They all have the same hardware, but the modems/firmware regulate the frequencies received. When an H931 is flashed to LS998 -- suddenly it has CDMA and all the Sprint LTE bands, etc. When US998 is rooted and flashed to H931 firmware it would have LTE bands 29 and 30, but not have those on US998.

If you feel you need Band 30, there's two ways of getting it:
1) Frankenstein to Canada H933 firmware. It has LTE band 30.
OR
2) root your current US998 and flash the TWRP-flashable zip for AT&T H931. It has LTE band 30.

More than half the things have nothing to do with my statement. This is the second time someone has said... US998 doesn't have band 71... H932 has it... when I didn't even say anything about band 71 or H932... that's amazing...
How did you even come to the ridiculous conclusion that all north american variants have the same hardware?

YOU said it, but I don't need you to say it since it's been proven over and over the past two years.
It's how Frankenstein works (which I wrote the guide for) to add or remove various bands, depending on firmware flashed.
Example, as I posted above (for some reason you don't understand "supporting evidence") LS998 has all the Sprint LTE bands. Flashing to US998, then the phone loses some of the Sprint LTE bands. Flashing back to Sprint firmware, the device regains all Sprint LTE bands.
My post was showing the differences in firmware modems, while all North American hardware is the same. H933 and H931 has LTE band 30, while US998 does not.
US998 has the major North American variants bands, but NOT ALL bands. My post detailed relevant examples.

Doesn't matter. They do have the same hardware. You listed 4 of the 6 (edit, 7) North American variants. You just forgot to list the other 2... (edit, 3) AS998 ("regional carrier" version of the US998) and T-Mobile H932, (and of course Sprint LS998). I'm including those two (edit, three). All North American V30 variants have the same hardware.
(We're not talking about options like internal memory or RAM -- because there's US998, US998U, US998R. But we just call them "US998". Same with H932 and H932U.)
It's not "ridiculous" as you described it. That fact has been been proven repeatedly by many people ever since Frankenstein was discovered to cross flash other V30 North American variant FIRMWARE and change bands to that variant, to transform one variant to another.
Anyway, you've been reported for your disparaging language. I'm tired of arguing with you in various threads.
I've told the OP how to get LTE band 30 on his phone, if he wants it. I've corrected your misinformation about US998 LTE bands, and provided proof.

Go ask anybody with H932 or LS998 running their respective firmware... and ask them for the FCC ID on their device... and then compare it to your US998 FCC ID...

Same hardware doesn't always mean same FCC ID. Same FCC ID means same hardware AND typically same bands -- like Verizon Droid Turbo XT1254 and Moto Maxx XT1250 which were clones of each other and have same FCC ID. It was how I proved the Droid Turbo was not exclusive to Verizon, even here in the U.S. You could run Verizon SIM card in Moto Maxx XT1250 because it was "Droid Turbo" under another model name.
But there may be cases where there's same FCC ID, but yet different bands...
I reiterate same hardware does not automatically mean same FCC ID. There are many reasons an OEM would file for different FCC IDs when dealing with different major carriers. For instance, if a carrier wanted a change it could impact all carriers if they all shared the same FCC ID. Especially with the requirements for the Americans with Disabilities Act (ADA), where electronic devices have to work in guaranteed manner for people with handicaps -- or companies can be fined or lose to class action lawsuits.

Rooted LG V30 - adding bands?

So now that all variants besides the T-Mobile V30 have root I am hoping maybe that opened up more options to get more USA bands working on my India H930DS.
I read a few threads about adding bands on older phones with root access particularly this one for the Galaxy s5:
https://www.google.com/amp/s/forum....o-add-rf-lte-frequency-bands-to-t2886059/amp/
It details the whole process of adding extra 3g and LTE bands on a rooted s5 with custom rom/kernel. He also states it should work on any Qualcomm based devices.
My question is will something like this work on newer devices such as my H930DS V30+?
Also i am not sure but i am assuming the "ids" he mentions in the steps 17-23 are going to be different?
Can any experts here confirm weather the process in the thread i linked would be relevant for my purposes or any other methods that can take advantage of root to add/enable more bands?
Ah come on. Someone at least give me some hope that i can keep this phone.
Back in 2015 we tried that Qualcomm method with Moto Quarks (Moto Maxx, Moto Turbo) and it didn't work. I don't know about LG phones.
I think no only one is answering because they really don't know.
All I know is when you flash Sprint LS998 to US998, it takes on those bands and loses a couple of Sprint bands. Sprint guy @JWnSC reflashed Sprint modem and got them back. So it IS possible to add/remove LTE bands from the V30. Whether it's possible in the way you need, I don't know. You're crossing hemispheres.
Alright thanks for the answer. I just don't want to go through the whole process of bl unlock and root just to find out I can't even get the tools to connect to the phone and read/write the bands or something stupid like that.

I can add, when I flashed the VS996 modem back after BL unlock/root, the hidden menu did not show the additional bands that, according to GSMArena, should have been present (46 & 66). Instead, it showed the native US998 bands and my connection was screwed up.
It may have been something I did or didn't do... I don't know.

Maybe some description of how to flash the modem correctly is what we need. I just flashed the modem partition using patched LGUP with the VS996 kdz.

Here's what I don't understand. If you flashed the H930 over your H930DS phone, these are the bands you should have...
If you have"H930" (either actual or converted), you will have these bands:
2G GSM: 900 / 1800 / 1900
3G (HSPA): 850 / 900 / 1900 / 2100
4G LTE: 1/2/3/4/5/8/12/17/20/28/38

So what bands are you missing that you need to add? I know Sprint users want LTE band 26 and 41, which can be added back by flashing the Sprint modem. I know T-mobile users would love LTE band 71 (probably not going to happen). Verizon users want Wi-Fi calling back and that's been solved.
But you SHOULD already be getting LTE on AT&T or T-mobile on the existing bands.

That is the problem I'm encountering. I flashed the H930 kdz on my H930DS and I am still not getting the H930's bands, only the H930DS'. I'm not sure if I did something wrong here. I also tried to use partition dl mode in LGUP to flash only modem, xbl and xbl2 from the H930 kdz but still no change. Any help?
I don't know, maybe 66? I think 66 is extension of band 4 right? Something I read somewhere. All I know is nothing I tried would let me get anything better than a 2g/edge connection at home and a 3g connection in town. It was constantly only being able to get 2g that bothered me. If I could have gotten a consistent 3g/hspa connection I would have been more than happy with it. Anyways I just gave up and sold it.
Which bands are you missing?
The bands listed for the H930 earlier is not correct either. It supports a few more than that.
---------- Post added at 08:56 PM ---------- Previous post was at 08:52 PM ----------
According to GSMArena, India uses these bands: LTE 850 (5), LTE 1800 (3), LTE 2100 (1), LTE 2300 (40), LTE 2500 (41). All of them except 41 is supported by the H930DS. It sounds more like your APN settings were wonky.
All I know is with the same SIM card I am getting LTE+ connection on my new essential PH1 in the same spot I was only able to get 2g connection with the h930ds.
So has anyone figured out a way to add LTE bands to their US998?
I am stuck with AT&T H931 firmware mainly because I don't want to lose band 30. The more I dig into the AT&T firmware, the more I dislike what the big brother did.

Because your H930DS is not made for North American carriers. It's missing most North American carrier LTE bands. So, all you could receive is 2G bands.
Has nothing to do with SIM card, has everything to do with you not researching what you bought. .
You should have bought Open Market US998 V30+.

You can root and debloat the AT&T firmware if you wish.

Converted H931 to US998 modem

So my phone has been running great since the conversion and still flys on ATT LTE, however I am a Mobile rep and I switch carriers on occasion, hence why I was wondering if the US998 modems actually enables the 800mhz CDMA band and allows me to use the verizon LTE bands.
Im not new to flashing and trying things out, and I can easily get my hands on a verizon android sim (yes there is a difference) to test anything.
Thoughts?

The US998 is the "carrier unlocked" version, and many people have used US998 on Verizon, so there's no question the US998 has that band.
Converting any other North America phone to that should let you have all those bands of the US998.

Ill have to test APN settings and clean boot with a verizon sim then. Ive tested a sim and it pulled phone number, but was still looking for signal.
Try making a backup in TWRP, and then flash JUST the Verizon system partition and see what you get.
rild is the daemon that talks to the modem, and Verizon may be slightly different.

So my phone has been running great since the conversion and still flys on ATT LTE, however I am a Mobile rep and I switch carriers on occasion, hence why I was wondering if the US998 modems actually enables the 800mhz CDMA band and allows me to use the verizon LTE bands.
Im not new to flashing and trying things out, and I can easily get my hands on a verizon android sim (yes there is a difference) to test anything.
Thoughts?

LOVE success stories like that.
What is the verdict? H931 on CDMA yay/nay?
It works just fine. Just depends on the rom you use. On stock us998 i can get verizon to work but on boombox, i cant get a signal.
Hello. I'm planning to buy H931 and do the Frankenstein conversion to us998. The question is H931 doesn't have the UMTS 900 band but if I do the process for us998 will I have UMTS 900 or is a hardware thing?

You will have all bands of US998.
The Frankenstein instructions make that clear.

Im sorry my English is not very good. But is unbelievable that H931 doesn't show UMTS 900 band on official description and doing the Frankenstein conversion you can add that UMTS 900 band. So it means that is disabled wow.
Another question. If the H931 AT&T model is not unlocked and I do the convertion then will be unlocked? Or I have to buy the unlock code for the IMEI???

Yes, AT&T H931 will be SIM card unlocked/network unlocked when you convert to US998.

OP, can you confirm that you can use LTE band 13 on your H931 (AT&T) Frankenstein phone? I converted my VS996 to US998 10b, unlocked bootloader, updated to 20e (KDZ), and rooted with magisk 17.3. I can use T-Mobile VoLTE but can't connect to their LTE band 12. I've tried the US998 Hidden Menu hack by using T-Mobile's LTE band menu and selecting LTE bands 2, 4, 12, 66, and 71. When I leave only band 12 selected I only get 3G or 2G EDGE. Maybe T-Mobile doesn't like my phone's IMEI as it's from Verizon. On AT&T, I never got stable LTE because my old G4 was from T-Mobile, and it always dropped to 3G after a while. If hardware isn't the issue then it leads me to believe T-Mobile whitelists only their branded devices for band 12.

I get the success message when clicking on band 13 in the hidden menu. I am using the latest stock US998 rom. Its given me the best reception and still runs fluid as can be.
Also, did you just insert your sim card into the phone from your previous device or did you manually enter your IMEI to your phone number in your T-Mobile account? Is the sim card brand new or several years old? Not being nosey or questioning your ability, just making sure your device properly activated on T-Mobiles network for best network performance. I don't think T-Mobile is picky with verizon IMEIs as 99% of verizon phones are sim unlocked out of the box and T-mobile likes to advertise towards verizon customers.

My T-Mobile service is actually through Tracfone. I activated it on a G5 H830 (TMO), and then moved over to a V20 H910 (AT&T). I did notice poorer reception on the V20 because I rarely locked into band 12. I always had excellent reception on the G5 and frequent band 12. I tried this SIM just now on a Canadian G6 H873 from Videotron, went into hidden menu *#546368#*873# -> Field test -> Modem settings -> LTE Band Selection -> Band 12. I instantly got Band 12 locked in, but went back to Automatic mode: (Field Test -> Network Mode -> Automatic). This band selection menu leaves you locked to that LTE band only, and you can't select multiple, so I went back and got Band 4 which is stronger in my house. If it were rooted, there's a hidden LTE menu that allows you to select multiple bands (through "tmo only" and iot menu, search LTEBand and BandSelection in shortcut master lite when rooted). Doing this on my VS996 -> US998 it falls back to 3G as it can't find Band 12 for some reason. I've tried wiping the modemst1 and modemst2 partitions to no avail. I'm now on the AS998 (ACG or C-Spire?) 20b KDZ. It should be identical to the LS998 (Sprint) modem and supports bands 2, 4, and 12. I kept TWRP recovery by not flashing the recovery in LGUP, INSTANTLY GO INTO FACTORY RESET (Power + Vol up) or else recovery will be wiped, flashed magisk 17.3, Disable_Dm-Verity_ForceEncrypt, lg-rctd-disabler, erased modemst1/2, and booted up. The hidden menu in the AS998 has all bands greyed out in the hidden menu only accessible through root, and the LTE band selection menu reports FAILED on all bands, so it's locked to the stock bands of the AS998/LS998. I'll report later on my findings.
TWRP Terminal command to wipe modemst1 and modemst2:
Code:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1 bs=16384
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2 bs=16384

I want band 12, I just found it amazing that OP has band 13 and CDMA on his H931 -> US998. Mainly because the H931 is GSM and shouldn't come with an ESN/pESN, just IMEI and MEID. And due to Verizon being picky about devices. I had an RS988 G5 and that didn't work well with them.

Not mine, I converted a VS996 -> US998 and don't get band 12 or 17. I the same SIM on a G6 from Canada (H873) and band 12 works on Tracfone via T-Mobile and on AT&T (prepaid).

No one else has said this, in fact the opposite.
I'm not talking about T-mobile at all, as they have put specific requirements on their band 12 due toWifi calling, etc.
But many are using us998 on T-mobile, whether converted or original.
That doesn't prove you don't have band 12. Also, ATT no longer calls band 17 as 17. On all newer phones, it's band 12, as 17 is a subset of 12. If you look at the H931 specs it says "12" , not 17. Their 12 is fully interoperable with T-mobile band 12 and includes 17.

LG doesn't have many international LTE bands? Any way to unlock them?

I'm debating between buying the LG V30s, G7, and S9+. I would prefer the LG ones because they support QC 3.0, but I travel internationally all over the place and need a phone with a ton of LTE band support (but I'm currently in the US).
I need 6GB of RAM, 530+ ppi, IP68/67, USB-C QC, and great cameras, so this is all I have to select from:
https://www.gsmarena.com/results.ph...mm=selected&sIPCerts=5,6&sOSes=2&idCardslot=1
The S9+ has 26 bands.
The LG V30s (US998R) only seems to have 11.

The LG G7 (G710ULM) is worse at 9.

I have a hard time believing that LG would create a different chip for all their different regional models of the same phone. The chip must support all the bands but a ton of them must get disabled in firmware. Is there any way to unlock them?

which specific bands are you looking for? The samsung exynos phones typically support a lot of bands, just not the us specific ones. Because of whatever contract samsung has with qualcom, their chipset doesn't support any of the sprint or verizon lte/cdma bands.
The us specific phones typically have the radios crippled and each rom supports bands for that specific carrier. the samsung s9+ snapdragon 845 (us version) has the same issue as the lg phones + they can't be rooted or bootloader unlocked.
the lg v35 unlocked supports a lot of bands, but again, no root or bootloader unlock
the oneplus 6t supports lots of bands and can be unlocked but its not a premium phone and is missing a lot of other features like sdcard, ip rating, qi charging, etc.

I'm not looking for any specific bands since I don't know where exactly I'll be traveling to. I just want as many bands as I can get just in case. On the USA side I just want TMobile support.
The US S9+ versions still seem to have a ton of band support, no? Their only issue is they can't be rooted, but is this a permanent problem or do all Samsung phones eventually get root?
If I wanted an LG G7 or V3x phone with 6GB and all that jazz I mentioned, do I have any options for one that had tons of bands and is unlockable? A European version perhaps?

There is sim unlocked and bootloader unlocked which are two different things. Two phones closest to what you are describing would be the unlocked s9+ from b&h and the lg v35 unlocked. Both will support around 22 bands and will be sim unlocked. Currently neither phone can be bootloader unlocked.

If you want information about any of these phones your best bet is to go to that section of the forum and ask your questions there....
While most decent 2017/2018 phones already support B12 & B66, not a lot of non-TMO phones support B71 yet. If you want to keep your new phone until 2019+, the phone should support it. That means your choice would be limited to the ones in TMO B71 list
FWIW, LG V30 H932 (TMO): WCDMA B1/B2/B4/ B5; LTE B2/B4/B5/B12/B46/B66/B71 LTE Roaming B1/B3/B7/B20/B38/B39/B40/B41

I travel a bit too but you'd get too many hits and misses with LTE if your destinations are still unknown.... I'd get the phone with best value proposition for daily TMOUS (IMO that's currently a used H932 in mint condition, easily found), and just deal with LTE abroad as the issue comes (get a local SIM, rent/buy a hotspot if needed, etc - you probably knew that prepaid data packs are normally much cheaper outside the US. I have a hotspot specifically for use in Asian countries I travel to).

Whereas for me on AT&T, the best value daily phone is the US998.

2G GSM: 850/900/1800/1900 MHz

4G LTE Bands: 1/2/3/4/5/7/12(17)/13/20/25/66
Only T-mobile subscribers would use LTE band 71, and most T-mobile phones still don't have it.
Don't forget about HSPA... Last time I was in Brazil, where their main LTE bands 3 & 7, my phone at the time had those, as does the V30. But STILL most of the time I was on HSPA due to their telephony infrastructure in rural areas. Point is, having good selection of HSPA bands is still your best "international" fallback plan for phones that don't have 99 LTE bands.
Don't obsess over having every LTE band for every country. For proof of that, look at T-mobile. TONS of people on this forum have the US998 on T-mobile. Their phones work just fine.
Thanks. I really want 6GB of RAM though, and the V30 doesn't have it. The other LG phones with 6GB of RAM either don't seem to have many bands or have a locked bootloader or both.
I ended up buying the Samsung S9+ G965F/DS. It's got root, 6GB RAM, and all the other features I'm looking for except QC 3.0. It's kind of a shame because I've been a Samsung user for the last 10 years and was adamant I wasn't going to get another.... but here I am.

Yeah, I'm in a bit of a tough spot.
I need 6GB because the only reason I'm upgrading from my current TMobile S5 is because 2GB just doesn't cut it for modern apps anymore and 4GB just isn't future-proof enough for me. My S5 doesn't have band 71 either but the day-to-day sluggishness of not having enough memory is FAR more of an issue than band support.
I *want* to get the unlocked SnapDragon S9+, but it's not rooted or bootloader unlocked yet and I don't know if it *ever* will. Even the S8+ still has problems with bootloader unlock and root, right? The only reason I'm still running the S5 is because the ability to unlock and install LineageOS saved it and allowed me to squeeze two more years out of it.
So can anyone say with 95%+ confidence that the unlocked USA SnapDragons will have BL unlock and root?
Ok, I'm now even less confident that the S9+ SnapDragons will get bootloader unlock and root.
Even looking back at the S7, LineageOS is only supported on the Exynos models and none of the SnapDragons:
https://wiki.lineageos.org/devices/herolte
https://wiki.lineageos.org/devices/hero2lte
Same for the S8s.
I'm guessing that this trend will only continue for the S9s.

The T mobile version sounds great to me because it would work great in Italy where I travel often. However I am planning to convert the H932 to us998 by flashing with LGUP for rooting. Does that mean I will loose the extra bands of H932 and have US998 bands instead?

1) You will brick your phone. T-mobile H932 has different RSA encryption than the other North American V30 variants.
This is why H932 can't use WTF method to install TWRP and root. It cannot be Frankenstein'ed to US998 for necessary fastboot flash commands.
2) Converting (Frankenstein) any North America V30 to another (not possible with T-mobile H932) makes it THAT phone, including all bands. After bootloader unlock and root, Verizon and Sprint users will often flash their VS996 or LS998 modems back.

That's NOT what you said. You said you were planning on converting T-mobile H932 to US998. That Root LAF method for T-mobile H932 by @runningnak3d has nothing to do with WFT method -- which for some V30 (particularly North American variants) mean at least temporarily converting to another model (like US998).

Anyway US998 actually has LTE bands 3 and 20 even though they are not originally included in H931. If that's true (doesn't require hardware modification?!) I will buy H931 ATT.
Thanks for your help!

I think you are somehwat confused. AT&T H931 has always had LTE bands 3 & 20. Note both links below are to LG.com website and those specs have been there since DAY1.
https://www.lg.com/us/cell-phones/lg-H931-Black-lg-v30
H931 (AT&T)
GSM/EDGE (2G) Bands: 850/900/1800/1900
HSPA/UMTS Bands: 850/1700/1900/2100
4G LTE Bands: 1/2/3/4/5/7/12(17)/20/29/30/38/39/40/41/66
LTE bands 3 and 20 have also always been in the US998 specs:
http://www.lg.com/us/cell-phones/lg-US998-Unlocked-v30
US998
CDMA: 800 MHz CDMA
2G GSM: 850/900/1800/1900 MHz
3G UMTS (HSPA):850/900/1900/2100 MHz
4G LTE Bands: 1/2/3/4/5/7/12(17)/13/20/25/66
Why not just buy US998 to begin with? Or buy cheaper variant like LS998 and convert to US998. I'm not understanding your logic. With US998 you get LTE bands 3 & 20, have CARRIER UNLOCKED, have fastboot flash commands so you can also bootloader unlock and root if you wish.
With H931, you are carrier locked to AT&T. Yes, you can get that unlocked -- but then you have no access to firmware updates as AT&T only gives updates via OTA to AT&T customers. This is why everybody and their brother CONVERT H931 to US998. To carrier unlock, get fastboot flash commands, AND get easy updates.

wow, thanks you gave me a great overview of the situation. On Amazon refurbished the ATT version was actually the cheapest.

Ok, I'm now even less confident that the S9+ SnapDragons will get bootloader unlock and root.
Even looking back at the S7, LineageOS is only supported on the Exynos models and none of the SnapDragons:

Same for the S8s.
I'm guessing that this trend will only continue for the S9s.

The G965F/DS is not snapdragon. The only samsung snapdrag phones that are unlocked are the hk and cn versions which again have crippled radios.
The best snapdragon 845 with unlocked bootloader and root would be the one plus 6 and thew newly released one plus 6t.
The lg v30s does have 6gb of ram and most likely can be unlocked using wtf method. But the bands will be more limited and its snapdragon 835.

Did LG really produce all these V30 and + variants will different hardware (radios), or just cripple them through firmware? Would be great to be able to unlock the phone's capability with a firmware flash.

On eBay refurbished "mint' US998 V30+ (probably converted LS998 V30+) is $295
Well I usually trust Amazon refurbished more but I ended up doing what you suggested . Cancelled Amazon and got V30.+ for $295 from ebay. Thanks!

Frequency/bands question

Hi,
I have a frankenstein v30 converted from at&t (currently on verizon).
I'm taking a trip to the phillippines and was planning on buying a prepaid sim when i get there and I just want to make sure that this phone is compatible.
Any way to check which bands are available?
Thanks so much

What firmware model did you use as destination during Frankenstein?
If you're on US998 firmware, then you have the US998 bands. If you're on VS996 firmware, then you have the VS996 bands.
US998 bands are listed in the Frankenstein instructions (see below). Verizon VS996 bands are easily searchable.
http://www.lg.com/us/cell-phones/lg-US998-Unlocked-v30
US998
CDMA: 800 MHz CDMA
2G GSM: 850/900/1800/1900 MHz
3G UMTS (HSPA):850/900/1900/2100 MHz
4G LTE Bands: 1/2/3/4/5/7/12(17)/13/20/25/66
Compare the bands for Philippine carriers listed in the link below with the bands in Chazz' post. Then choose a local carrier based on coverage where you're going (and price/allotments, of course).

Upgrading after root - how easy?

I'm looking to replace my aging HTC One M8 and it looks like the LG V30+ is the right phone for me, since it's got all the features I want (and no notch!) at a price I'm happy to pay.
One thing I definitely want though is Android Pie. I know LG hasn't released it yet for these phones but that it should be out in Q1 or Q2 of this year.
I also want to root my phone. I've skimmed over the instructions and it seems that if you do the rooting process it'll erase all of your private data off your phone, so it seems like I should do this more or less after I get the phone, rather than using it and wiping my stuff later.
But I've read that once the phone is rooted, OTA updates won't apply is that correct? I don't want to use any custom ROMs or anything, just the standard LG firmware. Do I need to flash to some other firmware and then manually install updates? What's the deal? How difficult / fiddly is it?
It doesn't matter if you're rooted or not. You will still be able to update as usual using KDZ. You can even update stock LG ROMs via TWRP with flashable ZIP. Keep in mind that unlocking bootloader needs stock 20a or 20b so if you update to the versions above that, you must downgrade later. So I think it will be nice to unlock your bootloader first after you get your phone, then you can decide whether to root or not after that.

I'm on stock rooted firmware myself.
OTA updates won't apply because you'll have TWRP custom recovery. But full image updates (KDZ) are always better than partial image OTA.
If you have TWRP, you merely install the latest TWRP-flashable zip file of the KDZ. It's like flashing a ROM, but it's stock firmware "ROM". Reflash Magisk then reboot. You "dirty flash" so you keep all your data. Takes 5 minutes?
If you read the WTF instructions, upgrading to newer firmware is mentioned towards the end -- Section 9, specifically. Read those Instructions in a web browser, not XDA app, or stuff will be missing. I also suggest printing them out to reference.
Ok, that's great, thanks!
What these KDZ files? I haven't looked around these forums much yet. Are they officially provided by LG, or do people rip them off their phones and upload here, or is it a mixture?

LG publicly releases the full image updates a few days after the partial image OTA update. The format extension is .KDZ. We post copies here in the forum, down on the dev section. A group of devs have graciously offered to convert the KDZ images to TWRP-FLASHABLE zip file, whenever updates are released.
For people who are rooted, just flash them in TWRP just like dirty flashing a ROM. Keeps all your data. Reflash Magisk, reboot. Done.
As an example, here are the KDZ and TWRP flashable zip files for the Verizon VS996:
https://forum.xda-developers.com/lg-v30/development/vs996-lg-v30-verizon-vs996-t3865398
The top one was released very recently. You can see there's a link straight to official LG Bridge update server as well as TWRP-flashable zip format, rendered by a Dev to "ROM".
It is possible to update to newer KDZ manually, without using TWRP. A little more complicated. But we don't need to discuss that right now since we do have TWRP flashable zip files.
Thanks very much for your help.

Where do you live, what V30 variant were you considering? If you live inthe U.S., what carrier do you use?
With V30, you can buy other variants and convert them to what you need -- especially North America. (There's one exception, which I'll explain after you answer.). But that's why a lot of people buy "mint" (like new) Sprint LS998 V30+ (128GB), even though they are not Sprint customer. It's often less expensive and has more internal memory than just the 64GB V30. They then unlock bootloader, root it, then convert to what they really want.
I converted two personally from LS998 V30+ to US998 V30+. You can even flash Verizon or AT&T firmware over them.
Or you can find already-converted "mint" US998 V30+ for very good price on eBay. Most US998 V30+ on eBay right now are probably former LS998 V30+ -- but that's OK most of the time.
Sorry, don't mean to confuse you.
I'm in New Zealand. The company I have bought from brings in the phones from Hong Kong. It's a 128GB model, although the website doesn't state which specific variant, but from what is available through other sites here I expect it to be a V30+ H930DS.
I'm aware of the root restriction with the T-mobile variant, which doesn't matter to me.
Is there a benefit to be gained by swapping the variant firmware? Is it just radio bands unlocked depending on carrier?

For H930DS, the other compatible firmware is the H930. Unlike the North American "Frankenstein", flashing H930 over H939DS does not change bands or anything. Hong Kong H930DS just got a new update with DTS stereo framework (needs root to fully enable), so you should stick to your firmware.
Whereas North America Frankenstein fully converts one variant to another, including all bands.

Root is easy, some custom roms available if you want to play. The v30 plus is a great upgrade.
I am still on stock and with root and magisk its easy to customise how you like it.
My m8 is a bit short on battery life now but still a great phone. Annoyingly I have Pie on there already working really sweet :silly:
Oh, I only miss the ir blaster to control the tv in the gym

Yeah, my M8 is still a decent phone although I'm just on Marshmallow. The battery is the main problem, it doesn't last super long (although recently I seem to be able to use it for longer? not sure what that's about). I've twice had it now where the battery is so low that when the phone has had less than 15% remaining it just shuts off, seemingly in the middle of some important process, corrupting some important system files and to recover it I essentially had to wipe all of my profile out of it - once this happened on holiday (in a city were I could get wifi, thankfully) and it took me several hours to get it working again, damn annoying.
Have also had it crash when trying to take photos with the flash on. Basically exactly the same problem that Apple got completely lambasted for - the battery is old and can no longer always cope with large spikes of energy draw, which can cause system instability.

Digicel LTE bands are 2/12/17
H930/LS99U/H933 support these bands but wasn't getting any good condition LS99U so went with the 933.
I live in Dominica in the Caribbean.
Also as a side note im stuck on one LTE band (17 cause it has most coverage) .
Tried the adb commands posted in another thread but kept getting the error "error (Cannot erase this partition in unlocked state). "

4G LTE Bands: 1/2/3/4/5/7/12(17)/13/20/25/66
I'm on AT&T which uses band 17. But in the U.S. now it's band 12/17. LTE band 17 is a subset of LTE band 12, so about three years ago, AT&T decided to just say their phones have LTE band 12 -- since they support ALL of LTE band 12 (which T-mobile has) as well as the carved out piece of LTE band 12 that is called LTE band 17. Even though AT&T uses LTE band 17, none of their phone specs now actually list LTE band 17 -- it lists LTE band 12 (which includes LTE band 17).
Band 12 contains the 700 MHz lower A+B+C blocks.
Band 17 contains only B+C.
The analogy I use is Miami = LTE band 17.
Florida = LTE band 12.
Miami is in Florida, so there's no need to say I have "Miami" and I have "Florida".
I got into an argument with someone about this a couple of years ago when AT&T changed their designation from Band 17 to Band 12. He was looking for a carrier unlocked phone that had LTE band 17 -- so he could use it on AT&T, and suddenly couldn't find any. I told him just what I told you (LTE band 12 = LTE band 17 on U.S. phones), and he didn't believe me. So, I sent him the link to the online AT&T store where all the AT&T-branded phones are with specs. NO AT&T phones show band 17 any more -- even though AT&T STILL uses LTE band 17! They're just calling it band 12 now... I challenged him to show me any post-2016 AT&T phones with the LTE band 17 -- which he and I both knows AT&T uses. Since 2016, AT&T no longer lists LTE band 17 on their phones specs, but older AT&T phones will STILL show LTE band 17 in the SAME location. Newer phones show LTE band "12" on AT&T in those locations.

It's me being ignorant of that fact that caused me to leave down the 998 and get a 933.
gsmarena was my go to source for bands on the diff models and as you explained the 998 does not show band 17.
i even asked my provider and their response wasn't so helpful.
just went with what seemed safer to me.
might sell the 933 and get a v30+ for the extra storage

Right, so I've had a look at the available TWRP ROMs and there's only a handful for the H930DS and none for my region (TWN).
So how do I go about flashing a stock KDZ, and will that erase any of my data?
You use LGUP to flash the KDZs. Yes, it will erase all your data, as this is effectively reinstalling the OS as if the device was new from LG.
The KDZ thread should provide instructions. ChazzMatt's thread here is specific to the 930 series: https://forum.xda-developers.com/lg-v30/development/h930-lg-v30-european-market-h930-t3779076 - near the bottom he details how to flash KDZ with the appropriate LGUP files as well.
I'm wondering if I can use one of the TWRP ROMs for the H930dS even if they aren't for the TWN region, or would that cause problems? Am I correct thinking the *only* difference is the cell bands enabled? Or do all H930DS support the same bands (except India)? Is there any site that lists the different bands for each region?
