I am looking at buying a tmobile H901 to unlock and use on Cricket (AT&T MNVO)
I know the tmobile version does not list band 17 as supported.
However I hear that the hardware for all the US variants is the same and it will activate bands according to the SIM that is installed.
My question is, If you have the H901 and put in an AT&T sim card, will band 17 work?
The towers near me use band 17
I just ordered an "unlocked" G5 H830 on Ebay, after carefully checking the LTE bands on the FrequencyCheck. I know I need bands 2 and 17 because I used the LTE Discovery App to determine that my carrier (AT&T US) provides LTE on in my area. But I just realized that other sites show different LTE bands for the H830 model...
FrequencyCheck LTE 1/2/3/4/5/7/12/17/30 (I hope this is right because I need Band 17)
The LG Website LTE 2/4/5/12/29/30, Roaming 1/3/7/20, and CA
Autoprime's helpful G5 thread LTE B1/B2/B3/B4/B5/B7/B12/B20
Can anyone confirm which of these is correct? Or verify that the H830 cannot use Band 17? Has anyone succeeded in adding LTE bands to the G5? Perhaps as described in this thread about phones with Qualcomm chipsets?
The moral of the story - check multiple websites when selecting a model with the right frequency bands for your carrier/area!

I know it's been a month
For att, band 12 support is equivalent to band 17 support. If you see a phone with band 12, it'll work on att's band 17
(12 is a superset of 17. Att has deployed mfbi on most of their network so that 12 phones can connect to their 17 network
Reverse is not true- 17 phones cannot connect to 12 networks since 17 phones are missing the nonoverlapping stuff in 12
That saying , I can't help with lte bands (h830 may or may not be missing 29/30 which att uses as a third lte layer. Not that important since you can rely on band 12/17/5 as first layer, band 2/4 as second layer)
I have V30+ (H932 /T-mobile version) I already get T-mobile Permanent Unlocked on my device.
Just realized that the bands availability for this device is not as many as Samsung Note 8 (T-Mobile version).
eg. no LTE band 8. The spec stated it has
GSM 850/900/1800/1900 MHz
WCDMA B1/B2/B4/ B5;
LTE B2/B4/B5/B12/B46/B66/B71 (USA-Tmobile)
Roaming LTE B1/B3/B7/B20/B38/B39/B40/B41
I will use this phone in the country that need LTE band 8.
by reading this thread;
https://forum.xda-developers.com/lg-v30/help/increasing-data-speeds-t-mobile-t3703325
It seems , I have found a way to get into engineering mode to get into band selection option and turned on the band I need.
but I have a doubt if this phone will be working especially LTE band 8 in my destination country where I have to Travel. (there is no LTE band 8 on LG V30+ t-mobile)
Can some one confirm and test to by switching SIM card, (must be temporary /permanent unlock), let say turn on band 17 from ATT since default T-mobile version is not available,
The area where I live T mobile and ATT use LTE band 4 so it is hard for me test myself with ATT SIM card if band 17 is working after I turned on that band.
Thank you

LTE band 17 is a subset of LTE band 12. All new AT&T phones now only list band 12, because it includes 17.
A lot of AT&T customers missed this news apparently:
AT&T’s 700MHz Systems Now Interoperate With Band 12/17 LTE
January 11, 2017

Here are the specs for the AT&T LG V30 H931 -- straight from both the LG and AT&T websites. DO YOU SEE BAND 17 listed on this AT&T phone?
No. Because LTE band 12 is listed -- therefore no need to list LTE band 17.
http://www.lg.com/us/cell-phones/lg-H931-Black-lg-v30
IF you go to the AT&T website to BUY an LG V30 H931 from them, here are the bands they show you are on the their own phone. Slightly different order from the LG.com website -- but still NO band 17. No need to show LTE band 17, since LTE band 12 is there!
https://www.att.com/cellphones/lg/v30.html#sku=sku8510583
The V300 I received from HK didn't have the B20 LTE band on the spec sheet.
But when i enabled it in the engineering menu, it worked perfectly with European networks.
There are some apps that give you the ability to record the bands number you encounter and log them.

Read my reply again. 17 is subset of 12. Even new AT&T phones no longer show "17", since they will now show 12. If you have 12, then you have 17. New AT&T phones will no longer show separate 17.
Even the AT&T LG V30 doesn't show 17. Why? Because 17 is already IN 12. (Like sugar is in cookies.)
But I'm repeating myself over and over. Just go read that post again.

There is no reason not to believe your point, as I already said "good to know"
I don't need to argue about it .
In technical point ATT band 17 is already covered by band 12 (T-mobile) which 700Mhz ( a )
for some people they just read band 17 is band 17 not band 12. and obviously they are thinking it is different with limitation of technical knowledge.
I just pointed out the frequencycheck.com
https://www.frequencycheck.com/carriers/at-t-united-states
I guessed ATT can't just stated they are using band 12 which they don't have (extended range LTE 700Mhz a)

AT&T now calls it band 12 on their phones moving forward.
Older phones will still show "17".
That site you keep giving link to is not an AT&T website and you have no idea when it was even last updated. I'm not even going to bother going to that site because I know I'm right. I really don't care what they say. They haven't kept up with current development.
It's why the AT&T LG V30 H931 on the AT&T website doesn't have LTE band 17 listed, but has LTE band 12 in the specs instead.
There are apps like LTE Discovery that will show you what bands you are on, and even keep a log as you travel around.

On my US998, here's the bands I am getting as I travelled to work yesterday morning. I was getting LTE bands 2 and 12. As expected it's now LTE band 12, not "17" -- because AT&T doesn't call it Band 17 anymore (except older phones will still show that). All new AT&T phones or new phones compatible with AT&T (like the US9998) will show LTE band 12.
https://www.reddit.com/r/tmobile/comments/47blo3/eli5_band_12_vs_band_17/
Band 12 consists of the frequencies 698-716 and 728-746. This band is the only band that covers the 700a block that T-Mobile uses, and also happens to cover the b-block and lower-c-block that AT&T uses.
AT&T is upgrading its network so that it can handle Band 12 phones, since Band 17 is a subset of Band 12. This means that people will be able to use T-Mobile phones on the AT&T network.
Additionally, AT&T's phones will begin coming with Band 12, which means they can be used on the T-Mobile network.

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.

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.
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?

Just an update. I featured it out. Had to go into the hidden menu *#*#4636#*#*, Phone information, turn VoLTE Provisioned = BAM! Back in business.

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'm confused. Do they want band 13 or band 12? They started talking about band 13, then started talking about T-mobile band 12.

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.

When you convert it with Frankenstein, it converts to have all the bands.

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.
