On H933, you should not only have LTE band 3 but should also have LTE band 8.

You may have to contact your carrier. They may have some database and your phone model is not whitelisted or allowed or whatever.

______

RAT LTE?

Are you messing with the Hidden Menu again? You should really never touch that. Use the regular Settings to choose GSM/WCDMA/LTE

or

GSM/UMTS/LTE

(Whichever one shows up in your choices, they are both the same thing.)

____

I keep telling you you cannot change modems when flashing H930 firmware to North American variants -- so please stop asking. ;)

First, I'm not going to ever recommend anyone flash a North American variant to an H930 variant. If you do that, you are on your own.

Second, if you do try to do that, you can't completely convert to H930. You have to exclude three different partitions -- including the modem, which totally defeats what you want (to change bands yet again).
[LG V30 Guides, News, & Discussion] rockzymen:
Yes, h933 it should be hve good band for my country.

But, the fact (in my phone) its very bad.. no get signal at all (always "cross" sign and "loading/searching" sign" at signal bar at the phone .

About RAT LTE, what i mean is not in hidden menu. (I never go to that menu again)

It is at = (Mobile setting > System select > network operator = Search Network... manual.. not "select atomatically" option

It listed the operators on my country, with the RAT type below the name operator...

About H930, okay... i will not going to that version.

And Now my phone is back to Us998-20h :D

Btw, i just find someone successfully solved problem on his phone (same problem like i had, No LTE, Only 3G). I find it at FB forum LG v30 Indonesia..... the funny is he doesnt know, how exatcly he got LTE signal...

His phone (at Oreo) are already never got LTE for long time, couple months... (he accept it). the when he know theres a pie update.. he tried to update it.... but unfortunately he brick the phone/bootloop...

Then he tried to back to Oreo again, (with LGUP store frame, he said he use refurbish) and when the phone on Oreo.. the LTE signal shown up.. with full bar.... LOL.

Now he dont want pie, he had LTE its perfect.. :laugh:

What a LUCK

How could it be?

[LG V30 Guides, News, & Discussion] sandreas:
After reading all pages of these 4 threads and more, I have some questions that are not answered to certainty.

I'm starting with a LS99821a, I find it has no hidden menus, so I can't control the LTE bands. I can't even do a fastboot getvar all. (Is there a way to get that?)

My goal is to measure individual bands, specifically what looks like a new Sprint network in my area, band# 26, the one not already covered by US998.

The frankenstein method in one place says I only need to restore the modem partition (after the clear instructions to downgrade to US99810d, LGUP PartitionDL to 20a, unlock, LGUP to final US99820h, and flash TWRP plus 3 scripts.)

What I don't have clear is the other 2 modem partitions, modemst1 and modemst2. In one place I read to restore them, in another to wipe them with fastboot erase.

Which path works?

Does anybody know where the field test modem hidden menus reside? is it in system or modem, or one of the other supporting partitions? I require those menus to work for my discovery mapping to succeed. http://seahorsecorral.org/cellular

Also, should I be concerned about LGUP-patched Dump giving a timeout error after 4.5 Gb, 22 files are written, that appears to be everything.

Thanks, Stewart
[LG V30 Guides, News, & Discussion] ChazzMatt:
Are you looking to bootloader unlock and root your phone?

Otherwise if you are still on stock Sprint firmware, why not just install LTE Discovery app and see the LTE bands you connect to.

You can run it in unrooted mode, even though this shows my rooted mode.

Or maybe I'm misunderstanding what you are wanting?
[LG V30 Guides, News, & Discussion] sandreas:
Yes I intend to unlock and get root and twrp.

Because LTE Discovery does not create logs of both serving and multiple neighbors, into a file I can process and map.

Over the last 3 years I have had LTE Discovery work less often for me, sometimes where I reverted to earlier versions to keep it working, so it fell out of favor.

G-NetTrack and Network Cell Info show all that info too, and create logs. NCI doesn't log more than one neighbor, even with the Pro version, but that's getting off topic.

I just want to know if I need to restore more than the modem partition, that I'll get both lte menus and band 26, and my other 2 questions I threw out, I'm not expecting much from.
[LG V30 Guides, News, & Discussion] ChazzMatt:
The "modem partition" part is what is confusing me.

Here's how it all works and you can decide if that's the information you need...

If you are a Sprint customer on LS998 you temporarily convert to US998 firmware using the WTF Instructions. Of all the North American V30 variants, only the US998 has fastboot flash commands. Since you have a North American phone you will be diverted to these Frankenstein instructions to do that conversion. Once you have bootloader unlock, TWRP and root, you then flash

latest Sprint firmware via TWRP flashable zip (built like a ROM

). That converts you from US998 back to LS998 while still retaining TWRP custom recovery.

You don't have to flash any Sprint modem partitions, etc. That's all included in the TWRP flashable zip, made by a dev [MENTION=6815443]JohnFawkes[/MENTION] who is a Sprint customer.

Back in mid-2019, BEFORE these Sprint TWRP flashable zips were created some Sprint customers manually flashed back the Sprint modems over US998 firmware -- because there's 3 Sprint LTE bands not included in the US998 firmware (or something like that). And there was no convenient way to get Sprint firmware back, since Sprint doesn't publicly release KDZ. So, to get all the Sprint LTE bands back they flashed the LS998 modems over bootloader unlocked, rooted US998. That is no longer necessary to re-gain Sprint modems after bootloader unlock and rooting, due to the TWRP flashable zips.

Now having said all that, if there's something the US998 has that you need (like fastboot flash commands) AND you also need Sprint modems, then yeah you will have to do some workaround.

The US998 does have Hidden Menu with the field test stuff accessible with root and I assume the LS998 firmware does also once rooted?

If you can't get to the Hidden Menu by the dialer, you can get to it with Shortcut Master app, but you need root.
[LG V30 Guides, News, & Discussion] sandreas:
I don't know why you are confused, all you typed seems to be on track. The part in bold is what you call a workaround, I'll call it path #2 if path #1 fails.

I am at the first possible end goal, and have JohnFawkes LS99830a installed.

Unfortunately no root. and no hidden menus.

Attempts to start MM fail as it crashes, it "keeps stopping."

Reading that thread, I find no clear conclusion how to get root. Canary or Beta something. The OP crossed out any need to take additional action to get root, which seems incorrect.

Before I restore, reflash and try for path #2, the second end-goal, mixing modem partitions with US998, I'll pause for advice how to get root.

Thanks
[LG V30 Guides, News, & Discussion] ChazzMatt:
For LS99830a, you have to flash Magisk to get root. But right at the time 30a was being released, was when that particular Magisk canary was going to next stage. So the "canary" version needed was no longer canary.

For whatever reasons one or two people went back to previous TWRP-flashable zip release.
[LG V30 Guides, News, & Discussion] sandreas:
Uninstall and install magisk-20.1.zip worked.

Unfortunately, getting access to the hidden menus, and the network menu, none of those work with this modem firmware. Only the Universal bands are on either list, (meaning the list that looks like the US998 and the checkable list that is on the H932 and includes band 71 etc, but no band 26) and they all fail. Even the engineering mode is empty of any data.

So this looks like a dead end for my project.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Sorry about that. You tried the Shortcut Master app? Where you search for the Sprint Hidden Menu items?

Not sure it works with the LS998, just don't want to to give up if there's something else can be done.
[LG V30 Guides, News, & Discussion] ChazzMatt:
See here...
[LG V30 Guides, News, & Discussion] sandreas:
Thanks for finding that ChazzMatt.

There's the Sprint menus.! Been a couple years since I last saw those menus on my Nexus5, RIP.

It allows control of bands 25, 26, and 41, but still no way to keep the modem from camping out on other bands. The Nexus I could edit the NVram with QPST, but now days that's more likely protected.

Then I turned off airplane mode and did some exploring, I can't find any of these menus to be alive, no live data. It's possible it requires a sim now? Bummer. Or I'm missing something... for now.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Maybe does require Sprint SIM card.

Yeah, the various hidden menus act differently. On T-mobile H932, you can click a band to ostensibly ADD a band (if the hardware is compatible). Whereas, on US998, clicking a band locks you to that band. :rolleyes:

Not sure how it acts on LS998.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Since your IMEI is still for AT&T H931, you will have to manually update via KDZ with the same Dev Patched LGUP you just used.

You can update to last Oreo US998 20h or you can attempt to update to Pie US998 30b. The US998 30b (first Pie release for US998) is a little wonky and many people right now are staying on 20h until another US998 Pie KDZ is released.

See the US998 Oreo and Pie KDZ threads for files and Instructions.
[LG V30 Guides, News, & Discussion] ChazzMatt:
As long as you are on full stock firmware, you can use "Upgrade" mode in Dev Patched LGUP and keep data. It's like a manual OTA update.

However that only reliably works up to the very last Oreo US998 20h.

You can try it with USS98 Pie KDZ, and has worked for some -- but others end up hanging on the LG logo and not getting past that. For them takes Refurbish and a lot of other tricks.

Once you update to Pie KDZ, there's no reason that "Upgrade" wouldn't work again. It's just getting to USS98 Pie is difficult with this first Pie KDZ.

I really need help on this,i have the ls998 and i flashed nougat. After flashing nougat i followed the master reset. Now the phone has been restarting itself every 1 min and it wont allow me to access anything on it. This has been preventing me from flashing back to oreo. Some should please help me
[LG V30 Guides, News, & Discussion] ChazzMatt:
You say youflashed Nougat, but you don't say WHAT Nougat your flashed...? Which variant Nougat KDZ did you flash?

US998?

Are you SURE you flashed US998 Nougat instead of accidentally flashing US998 Oreo? Tell us the KDZ number. I don't believe you until you verify. People have confused the two before. They download both KDZ and then flash the wrong one. Your symptoms sound EXACTLY like that. That's exactly why you have to flash US998 Nougat first...

Flash US998 Nougat AGAIN, this time using the Nougat KDZ. ;)

Tell us how you are doing Master Reset.
[LG V30 Guides, News, & Discussion] mk1129:
Thanks a lot!

I followed the same practice and got the stable Android 8 OREO: US99820h_00_0318.kdz, but I made a wrong move to flash Android 9 Pie: US99830b_00_0902.kdz directly on that and bricked my Sprint V30+ (LS998) with booting hangin on LG logo...

The hard part now is how to shut down the phone :(, can't find a way to get in Recovery mode.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Try Master Reset. Many people can't get to Pie, hangs on the LG logo and they have to reset their phones to get back to Oreo.

Really don't recommend Pie US998 right now.

On my backup phone (former LS998) I had no issues getting to it, but I went straight from Nougat to Pie via Refurbish mode. Now that you have tried and failed (from Oreo), that probably won't work for you. Once you attempt Pie, your phone is permanently changed.

You will have to do all the other workarounds in post 6 of the Pie KDZ thread.

On my daily phone I am still on 20h Oreo, on purpose. There's nothing about Pie right now that has any advantages over last Oreo.
[LG V30 Guides, News, & Discussion] Kacike27:
The steps I have followed to pass the H931 to Pie have been:

1) flash US998 Nougat 10d_01_0411 via Partition DL, all partitions.

2) Master Reset

3) flash US998 Oreo 20h_00_0318 via Partition DL, all partitions.

4) Master Reset

5) Flash to H933 Pie 30k_00_OPEN_CA_OP_0906 KDZ via Partition DL,

all partitions except the partitions of Modem, Xbl and Xbl2.

6) Master Reset

I could not install Pie of us998, since I stayed in the LG logo

This is the only way by which I have been able to install Pie and keep mobile data running

Sorry, this is the V30 (Joan) forum, not the V35 (JudyP) forum.

V30 variants include V30/V30+/V30S. All are "Joan" Snapdragon 835 series.

V35 (JudyP) is a completely different phone, with Snapdragon 845 chipset, etc. V35 is basically a V40 (JudyPN) in a case that looks like V30 -- but has nothing in common with V30 whatsoever.. It's a V40 in disguise. ;)

[LG V30 Guides, News, & Discussion] ChazzMatt:
If you wish to use H933 instead of US998 you can. Here's the differences:

Yes.

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

CANADA H933

2G GSM: 850/900/1800/1900

3G UMTS (HSPA): 850/1700(AWS)/1900/2100

4G LTE bands: 1/2/3/4/5/7/8/12/13/17/20/25/29/30/66

The main advantage US998 has is fastboot flash commands, for bootloader unlock and TWRP installation. Canada H933 seems to have 3 more LTE bands, while USS98 does have CDMA (but most people outside the U.S. don't need that).

You would merely use the Frankenstein instructions, but instead of converting to US998 you would use the Canada Nougat and then Canada Pie KDZ, found in this forum. Don't ask me for links, you can go find them in the ROMs section. ;) Just go to the ROMs section and search for "H933". For Canada KDZ you need to use Partition DL mode with ALL partitions using the Dev Patched LGUP, found in the Frankenstein instructions.

What variant do you have? What is "this phone"?

Also what is your goal? If you are on Pie, you already have the latest firmware. BUT maybe you want to carrier unlock your phone or even Bootloader Unlock and Root?

* Are you looking to carrier unlock your phone (I don't know what you have, so I don't know if it's carrier locked or not)

* Are you looking to Bootloader Unlock and Root your phone?

* Maybe both?

Can't give you answers until you give more information.

If you are already on US998 firmware and want to Bootloader Unlock, you do NOT need to Frankenstein the phone. You already have fastboot flash commands. (And yes, US998 is carrier unlocked.)

You need to read the WTF INSTRUCTIONS. See first screenshot. That is the beginning. Fastboot flash commands. Early Oreo.

20h is the newest Oreo. You need one of the oldest. The top of the US998 Oreo KDZ thread tells you EXACTLY what you need, in big red letters. See last screenshot. So why did you install US998 20h?
