That would be plenty. And I don't even need 66 and 71! (I'm on AT&T Prepaid.) But just in case... ;)

Just added a screenshot showing bands 66 and 71 selected. I do plan on making that drive to verify Band 71.
[LG V30 Guides, News, & Discussion] jcsww:
Although i can't remember exactly off hand. I believe it was posted somewhere that the T-Mobile version actually supported bands: 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 20, 28, 29, 30, 38, 39, 40, 41, 46, 66, and 71.

Would the person confirming this mind testing all of those enabled at once, please and thanks?
[LG V30 Guides, News, & Discussion] vinniej:
Here you are good sir (or ma'am...don't want to assume). I was able to select all of the bands you requested.

Hi guys, I have a T-Mobile V30 and whenever I hit Reset at the bottom of the Band Selection menu, everything goes back to normal. Ie, I've locked to B71 only then hit reset and B2, B4, B71 all connect just fine, and CA where applicable. PS: there is another menu called "LTE Band Selection" and it does not have Reset at the bottom. BE VERY CAREFUL if you encounter this menu, I almost screwed up my phone until I found the "Band Selection" menu.

Since you have root, Network Signal Guru is also another tool to assist in locking bands and or verifying what's activated and deactivated.

If you have any more questions about the V30's engineering menu, Network Signal Guru, or B71 let me know.

[LG V30 Guides, News, & Discussion] ChazzMatt:
But this is NOT the T-mobile H932. This is the US998, rooted. The engineering menus are different. This LTE Band Selection DOES have reset. See it at the bottom of the screenshot?

Whereas, on the non-rooted US998, there is another LTE Selection menu which only allows you to choose one band at a time. Yes,

that one can mess you up.

But the menu shown in the OP of this thread shows LTE band menu with check boxes, where you can choose whatever bands (plural) you want to enable -- and has re-set.

Also, this thread shows how you can use root to populate MORE bands into that menu.

THIS is EXACTLY what everyone has been begging for -- and as soon as [MENTION=4360019]vinniej[/MENTION] or somebody else provides definite proof that LTE bands 66 and 71 are not only chosen but have reception, then there would be no reason to buy a T-mobile V30 H932. The US998 V30 has root and would have all the T-mobile bands. ;)

Thanks for explaining it [MENTION=3250376]ChazzMatt[/MENTION]
[LG V30 Guides, News, & Discussion] JWnSC:
Chaz do you have bands 25 and 26 also?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Are you asking do I have 25 and 26 normally on AT&T? Yes, at least 25. I don't see 26. This is a pre-root screenshot from my V30, posted in another thread., from my AT&T SIM card on AT&T Prepaid.

I have not attempted what's in this thread yet, as it was just posted last night. I only have time on the weekends to actually mess with my phone.

My V30 US998 (not my daily V30+ US998) is rooted, has TWRP and Magisk. But for some reason it didn't recognize my AT&T SIM card, even though that same phone had used the exact same SIM card for WEEKS before I got my V30+. :rolleyes: I was going to have either factory reset everything and start over or create an APN from scratch. By this time it was Super Bowl Sunday afternoon... so I put the spare phone away. :p Right now I'm still using unrooted V30+ as daily driver.
[LG V30 Guides, News, & Discussion] cstark27:
I wasn't suggesting anyone buy a T-Mobile V30. I read the OP and wanted to offer my insight, after having used the menus extensively. I completely understand what you said, you just repeated what I typed essentially so sorry if there was some confusion. I'm not asking for help with my phone, only trying to help you guys.

[MENTION=4360019]vinniej[/MENTION] mentioned not knowing how to restore the "default bands" that's why I mentioned the Reset button. But, Network Signal Guru is another tool as well.

Cheers...
[LG V30 Guides, News, & Discussion] ChazzMatt:
I understand you were trying to help. However, your post -- unintentionally -- did cause some confusion, at least in my mind and [MENTION=4360019]vinniej[/MENTION]. I know you only meant to help, and I thank you for that. But you have not used the US998 menus extensively (have you?). There are differences in the hidden menus between those models, just as there are differences with the Verizon V30 menus.

Maybe with root, now there's less differences or no differences since we can access "all" menus now? I don't know.

Yes, with root, this "new" LTE Band Selection menu is now like the T-mobile menu discussed and shown in other threads. However, your screenshots are different, probably because you are using an app to access them?

I do not mean to denigrate your contributions in any way, but felt I had to clarify there IS a reset button on this LTE Band Selection menu and you can check off what you want and don't want.

This thread is EXACTLY what everyone has been asking for. All we have to do is confirm there's actually reception on these new bands.
[LG V30 Guides, News, & Discussion] vinniej:
When I hit the reset in the LTE Menu, I get a "Reset Failed" toast. So I'm not sure it functions in the same fashion on the US998 as it does on the H932.
[LG V30 Guides, News, & Discussion] cstark27:
I understand now, thanks.

[MENTION=3250376]ChazzMatt[/MENTION] the screenshots were from the app I mentioned (Network Signal Guru), sorry for the confusion. The function should be free. The LG Band Selection menu shown in OP is exactly the one I have access to, and I have access to the other one as well that only lets you select one band at a time.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, that other one -- one band at a time menu -- is what

messed up my pre-rooted US998 V30 and others

. Some people said factory reset or even airplane mode fixed that, but others were never able to get off the one-band only mode.

I wished at the time we US998 users had access to this T-mobile style menu, where you could check off what you wanted or didn't want. With root now, we have more power to control our phones. The guide in this thread gives us that.
[LG V30 Guides, News, & Discussion] cstark27:
Yes I almost bricked my V30 by accidentally selecting a non-T-mobile band. Factory resets didn't bring service back until I found the Reset button in the other menu. But anyway, I won't stray off topic anymore. Good luck in your hunt!
[LG V30 Guides, News, & Discussion] JWnSC:
Ok. I was curious if those bands were available on the US998 model(bands 25,26,41). I planned on picking one up to use after I sell my LS998(Sprint model). Have to Wait till March before they will unlock. I will change carriers soon so not a big deal but would be nice to know for other Sprint users.
[LG V30 Guides, News, & Discussion] ChazzMatt:
It's also possible certain bands show up depending on carrier SIM card used. Mine is AT&T Prepaid which doesn't have roaming on other networks. (Yet, I still have Verizon's LTE band 13, so go figure.)

As you saw, the OP was able to add all these bands to his rooted US998 menu. Just waiting on reception confirmation.

Thanks for the awesome write-up. Was able to easily follow along and now my US998 has all 5 of the T-mo bands selected and saved. I do travel overseas occasionally and am wondering what I would need to do before I left the US in order for T-mo data to work. I'm going to Ireland next month and will be around Europe for a while so wanted to see what bands I should be using. I tried to select all the bands listed available and hit save but got a SAVE FAILED toast notification doing that.
[LG V30 Guides, News, & Discussion] vinniej:
Try and see if you can select the bands listed above. I was able to select these bands. I do know that you cannot select all of the bands as you will get the "Save Failed" message.
[LG V30 Guides, News, & Discussion] jcsww:
Looking at my V30+ from T-Mobile, I forgot band 25. Still, they are all selectable on the H932 and it would seem that they can all be saved on the US998. Once comfirmed as working, I will put in an order at B&H, which doesn't have any V30+'s in stock currently.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Don't order US998 V30+ until that IMEI range is (hopefully) added to the LG Developer Bootloader Unlock list website.

Right now, it's only:

*H930 (European V30),

*H930G (European V30+), and

*US998 V30

variants which can be bootloader unlocked and rooted.

Considering LG finally got around to the V30 US998, I'd rather buy another V30+ than a V30. The extra storage really goes a long way when loading it up with music. Maybe it will finally make the list by the time B&H gets more in stock.
[LG V30 Guides, News, & Discussion] Septfox:
I've posted a link to here on the v30 reddit. Hopefully someone there is living within range of one of the upgraded towers, and can test b71 without even having to get up.

Pretty exciting stuff. If it does indeed work, that's pretty much it for me; that was the single thing that would have kept me from getting a v30, barring any serious defects appearing with the phone. It's literally a straight upgrade from my Turbo in most ways that matter, and it'd allow me to get away from Verizon's network (though I acknowledge that I would have to limp along on T-Mobile's current coverage in my area for some time).
[LG V30 Guides, News, & Discussion] ChazzMatt:
If for some reason these saved bands aren't being received, the next step would be to try flashing T-Mobile radio over the rooted US998.

I know we do stuff like that with other phones (Moto Quarks). Can this be done with LG?

That was my thoughts exactly if this did not work.
[LG V30 Guides, News, & Discussion] N4cr2k:
I'm on AT&T. Going to try and run LTE discovery for a few days to see what bands my phone picks up. According to Wikipedia, I could see 2/4/5/(12/17)/14/29/30. The new 2300 MHz WCS band 30 is the one in particular I'm interested in. As ChazzMatt pointed out, we may need flash the carrier radio to fully get it working.
[LG V30 Guides, News, & Discussion] runningnak3d:
No. The modem is one of the pieces of firmware that is signed with an RSA signature. If you flash a modem with the wrong sig (which the US998 and H932 most definitely are), your phone no longer boots. This is "safe" to test if you want since fastboot is still available so you can fix your phone :)

[LG V30 Guides, News, & Discussion] Septfox:
More of "arrgh, Qualcomm", as I understand.

I'm sure you've already answered this in one of the other threads, but: given the (comparative) degree of freedom that the unlocked bootloader, non-useless recovery and root access all give us, is there still absolutely no way to bypass or disable signature/hash checks for the other partitions?

Or another route: allow the phone to partially boot using the stock radio firmware, then somehow load up modified firmware from an image before Android boots, kind of like Safestrap does?

Also, and I know this is probably a stupid question: is it possible to hook into the boot process and intercept the signature returned by a given partition, instead using the sig from one of the stock partitions to allow it to pass? Or is it all handled in hardware or something?

---

It's kind of annoying that bootloader unlocks, once hailed as the biggest step to enabling full use of the phone, only gets us halfway these days : \

I agree with what was said in another thread; it'd be nice if one of the other SoC manufacturers would step up their game. "Fast and under full control" is better than "blazing-fast and locked down to almost black-box levels". Not looking forward to seeing the fun things they're going to pull with the next couple Snapdragon iterations.
[LG V30 Guides, News, & Discussion] N4cr2k:
So far, enabling the other bands hasn't worked (on AT&T). So maybe there is something else that needs enabled/configured for it to work. I'd be curious if this worked for the TMO folks.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Which additional AT&T bands have you tried to enable on AT&T that doesn't work?

For instance, Band 71 is a T-Mobile LTE band. You're not going to receive it with an AT&T SIM card.

Yes, I'm curious if it works for T-Mobile customers too.

You have confirmation it's been deployed in your area? When AT&T added LTE band 5, it took me two years to see it on LTE Discovery logs -- even though I knew my phone had that band. Now, I see it all the time.

AT&T just had not yet deployed it in the Atlanta area yet.

[LG V30 Guides, News, & Discussion] N4cr2k:
So I did some more testing yesterday. I removed all bands from the selector except 30, and LTE discovery confirmed I had no LTE coverage. So this would appear that the selector is capable of enabling or disabling some of the bands. I was doing some research on frequencycheck.com and it looks like the V30+ has one extra LTE band, B30 (2300 WCS).
[LG V30 Guides, News, & Discussion] crescentmage:
Has anyone had a chance to test band 71 in a T-Mobile area where it is live? It's the main question holding me back from purchasing this model.
[LG V30 Guides, News, & Discussion] vinniej:
No - I have reason to believe this will not work on B71 at this time. B71 does not simply enable via this menu. However it is not entirely out of the question. Work in progress at this time.

Reading through all the posts it is not clear to me - has anyone confirmed band 71 is working using the method in the OP yet? I am a T-Mobile postpaid customer. I am traveling to the Michigan Upper Peninsula this weekend so I am going to root my B&H US998 V30 tonight so I can enable band 71 and hopefully at least get some kind of data reception in that remote area. I can report what I find out. Do we also have a consensus yet on which and how many bands we can enable at once? One of main reasons I purchased the phone was I assumed I would be able to enable band 71 with root.
[LG V30 Guides, News, & Discussion] vinniej:
The answer to your question at this point is no. I started this thread with the same assumption as you, however it has not been confirmed. You can enable all the bands up to 66 on the US998 (using the methods I mentioned), but 71 still proves to be elusive. I dropped the band 71 effort in lieu of school and life, but may get back to it when time affords.
[LG V30 Guides, News, & Discussion] 357wads:
I can confirm simply enabling band 71 through the hidden menu does NOT work.

I traveled to various locations throughout the UP last week and through the weekend that are supposed to have band 71 such as Munising and could not connect to it. I doubt it is a hardware limitation. I purchased the Nexus 4 back when it was a new 3G device, but with LTE hardware. I enabled LTE on that phone using the hybrid radios developed for it. If we can obtain the T-Mobile H932 radio we could maybe just flash it and be done or make some hybrid versions if necessary.
[LG V30 Guides, News, & Discussion] patato21:
I've said this before, but I managed to flash the H932 20o modem on my (VS996 -> US998). Only problem is it broke the network, WiFi, and Bluetooth while using stock US998 20e. Also the IMEI field was blank in phone status. The phone bootlooped when using Resurrection Remix 6.2.0 8.1 (AOSP). Also the H932 modem is 110 MB in size, while the US998 modem is 94.5 MB in size. Perhaps re-partitioning would fix this?

I tried the H932 modemst partitions with the US998 and H931 modems but it seems to have been overwritten or reset as it takes ~2 minutes after boot to connect, just like when I wiped modemst 1 &2 with

dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1 & modemst2

. Also I get no sign of LTE band 12 or 71. With the H931 modem + modemst, I at least get band 12.

I'm back on H931 modem and modemst as I never get band 12 on US998 modem despite many attempts. Looking for someone on an original US998 (no frankenstein) to provide me their modemst1 & modemst2 partitions ?.

You can get them with LGUP DUMP or if you're rooted, to this through ADB.

dd if=/dev/block/bootdevice/by-name/modemst1 if=/storage/sdcard/modemst1.img
dd if=/dev/block/bootdevice/by-name/modemst2 if=/storage/sdcard/modemst2.img

This map here shows T-Mobile's band 71 towers and coverage: https://bit.ly/2VrmFqW

Hello everyone,

I have LS998 flashed to US998

phone works perfectly except weak cellular reception compared to my old phone and my friends' phones also.

now I want to try to flash another modem to my phone to solve this, when can I find modems from other models (930, 931, 932 etc.) i need only bands B1 and B3 actually.

when can i find modem files and instructions to flesh them ?

Thank y very much.
[LG V30 Guides, News, & Discussion] ChazzMatt:
You keep posting the same thing over and over. What do you mean your "old phone" and your friends' phones?

Modems are found in all the KDZ posted in the ROMs section. You can flash them with LGUP in DP Partition mode but ONLY check mark the modems. Do NOT try to flash anything from T-mobile H932 on any other V30 phone. It won't give you extra bands but might give you a brick.
[LG V30 Guides, News, & Discussion] vmizandari:
i posted this first time.

old phone is xiaomi mic4c and friends phones are redmi note 5, galaxy s 6, sony xperia z

so you mean just not flash modems from t mobile H932 yes?
[LG V30 Guides, News, & Discussion] ChazzMatt:
I haven't cross flashed any modems, except when I cross flashed EVERYTHING, when converting LS998 to US998. I haven't ONLY cross flashed modems, but others have.

Do NOT cross flash anything from H932 to other V30. It has different RSA encryption, and it's too hard to remember what few partitions are not encrypted vs the majority which are.

I'm not sure band 1 is enabled by default but looks like your carrier also uses LTE bands 5 and 7. Those should be enabled by default.
