No OTA updates after flashing

Hello. I have successfully flashed my verizon V30 to the unlocked variant (US998) and it's been working very well for me on T-Mobile and Metro. The only thing I've noticed is that I have not received any OTA firmware upgrades even though I know security updates have been released... Is there a way around this issue? Is there a way to sideload these updates without unlocking the bootloader and / or installing TWRP?

If the only way to get these updates is to flash the new images via LGUP then that's fine. I just need the files and need to read up on how to do it again, as it's been a while...
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, for you (not bootloader unlocked) use Dev Patched LGUP to flash latest US998 KDZ in UPGRADE mode.

Takes 5 minutes, you don't lose data.

For Clarification

Must I use the modified LG UP as before, or the OEM version? What is the correct version of LG UP, I just want to be absolutely sure with this.

Also, can I go directly from US99820a to US99820e? or should I take intermediate steps?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Use the one that says patched attached to post #1 of that KDZ thread. Remember, it has to be installed where the "regular" version would go. You probably still have it on your computer, right?
[LG V30 Guides, News, & Discussion] RoboticNerd:
LG UP Install

I still have LG UP installed from when I first flashed everything. So I'll put my V30 in download mode and place the file in the upgrade section and begin. Simple as that?

EDIT: You're sure I shouldn't lose my data?
[LG V30 Guides, News, & Discussion] ChazzMatt:
If you use "upgrade" mode -- double check! -- no, you will not lose data. I've done it many times on friends' phones.

However, default mode is "refurbish". Do NOT run the process while still on "refurbish". I did that with my wife's phone last month. I was trying to do two or three things at once, and got distracted. It finished quite quickly and completely wiped her phone.

If you want, you can use LG bridge to backup your phone. It's almost as good as TWRP. But works for all phones, you don't need root.
[LG V30 Guides, News, & Discussion] RoboticNerd:
Thank you, backing up now.

I'll update when I'm done!

EDIT: DONE! No issues whatsoever. Thanks!

EDIT 2: One issue. Not sure if this would be solved by clearing the system cache (which I probably should have done anyway after upgrading), but the camera will freeze while recording video... Will update if I fix this :/

Update: It seems to be working after clearing the cache and restarting :)

Hello,

i get crazy.

I alwas get an error message when i start the crossflashing

RX timeout: 1.5

I allready used different computers, cables, reinstelded LG UP and drivers.

Does anyone a have an idea. I allready read the whole post, but i don't want to be the 1 of 1000 that is to stupid to do this crossflash

I have a H931 and want to flash to US 988

Christian
[LG V30 Guides, News, & Discussion] ChazzMatt:
1) Tell us which US998 KDZ you're trying to flash, when this happens? Should be Nougat US998.

2) Try downloading another copy of dev patched LGUP from the US998 KDZ thread, instead of this thread. Should be the same, but a handful of people said they couldn't get the copy on this thread to work. So I told them to download a copy from another thread.

3) Go into Download mode manually before opening LGUP.

4) Last, the very last, maybe factory reset your phone before starting this procedure? That should not be necessary BEFORE you start the procedure -- the phone will be factory reset anyway DURING the procedure -- but I'm just throwing out ideas. Maybe something on/about your phone is preventing this from working.

Maybe you can open the screenshot. It shows that i should have the right kdz (US 988 nougat).

Strange is, that my LKUP version has much more options than the ones in this thread.

Christian
[LG V30 Guides, News, & Discussion] cthiessenh:
I forgot to say, also strange ist, when i connect in download mode the V30 ist not detected by the computer. It starts the download mode and tells that it is waiting for connection. When i take out the USB cable and reconnect, then it's detected. It's also detected in LGUP, like you can see on the screenshot.

Hello friends!

Got in a trouble - have ls998 V30+ - wanted to unlock via crossflash into us998 - after I've made that it stuck on V30 logo. When I try to perform factory reset via volumeDown+Power - "Factory data reset is disabled by Kill switch"... What should I do now? :(
[LG V30 Guides, News, & Discussion] ChazzMatt:
US998 which? Nougat, Oreo? What stage are you stuck at?

Try

Master Reset

, not Factory Reset.

"Kill switch" error message is usually caused by LG Mcafee on the phone.

doesn't matter Nougat or Oreo - with both phone was stuck on V30 startup logo.

and yes, under FR I've meant Master reset....
[LG V30 Guides, News, & Discussion] ChazzMatt:
Well you can't go straight to us999 Oreo. You have to go to Nougat first, do Master Reset. That's why I'm asking.

HOW are you flashing? DL PARTITION?
[LG V30 Guides, News, & Discussion] Ramonsterator:
I've tried flashing Nougat first - couldn't do master reset due to kill switch, flashed Oreo - same thing...

Right, flashed thru dl partition

Was it US Cellular or Open Market Firmware? Is what you're trying to flash a downgrade compared to what's on the phone? Just throwing out some ideas for what may have caused it.
[LG V30 Guides, News, & Discussion] ChazzMatt:
There's no difference between the two.

Yes, he was going from Oreo to Nougat.

The AS998 he flashed the LS998 successfully is AS998 Oreo 20B. Both were Oreo, before and after.

And the brick was US998 Nougat it's tried to flash. Attempt from Oreo to Nougat.

Maybe people who successfully flashed LS998 to US998 did it when both have same OS version -- in this case, Nougat. US998 doesn't have Oreo yet.

So i had lg v30+ ls998 oreo

Use lgup=partition dl to flash us998 nougat

Now my phone is a brick.

Repeat the process trying now to flash as998 oreo on us998 nougat, my phone is still a brick.

Now i use option ChipErase in the lgup, delete system and everything, put the phone again in download mode and trying to use partition dl as998 file and flashing again. It's going really super slow. Waiting yo see what will happen.!?

Yuhuu, yeey lol :laugh:

After chip erase I install as998 partition dl again, took much longer to install but it works perfect now.. ONLY WHEN I DID CHIP ERASE IT ALSO ERASED MY IMEI AND THOSE INFO AND NOW THAT INFO IS EMPTY LOL. SO MY PHONE DOESN'T HAVE IMEI
[LG V30 Guides, News, & Discussion] jcsww:
Nice! It makes me wonder if that is what other models need to resort to in order to actually turn, for example, an H933 into a US998. Not having an IMEI though isn't good. Did it wipe the serial number too?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Well, I must say your experiences have educated everyone.

Now we know what "chip erase" does. You will probably have to Google for a way to restore your IMEI. I am not suggesting you change your IMEI, but you probably need to restore the one you had. It's printed on your box, so don't lose that.
[LG V30 Guides, News, & Discussion] datechnerd:
*#546368#*998# - SVC Menu - CRCWIZARD Test - Auto MID.

I mean that is more my test phone, it's blacklisted anyway lol. I will try few more things with it but idk should i try to put H930 on (now) as998. I don't want to kill my device totally, as long i have download mode I'm good, but without that I'll have glass brick. I'm using that phone to be my second camera for my YT videos. This is my IMEI now. Phone doesn't have sim card in it. It's not Plus version either. Now it's just LG V30Thinq as998 without right IMEI and s/n lol.

REAL FRANKENSTEIN PHONE omg

I will try today to erase the chip again and then again try to put us998 nougat on as998 oreo. I think it will work. Still i don't recommend that to no one bc idk what the heck just happened with my imei, sn, etc. If flashing of us998 will not succed then I'll not even try to flash h930 on it. It doesn't have sense. It will be n interesting day so please guys stay online ???

I know we saw an H933 "V30+" that was probably previously a Sprint LS988 V30+. So, may work both ways? But you don't want to flash your H933 to LS988. That's like running INTO a burning house.

You could probably flash to AS988, but not sure what the benefits would be for you. AS988 is basically U.S.regional carriers US998.
[LG V30 Guides, News, & Discussion] jcsww:
The only change I was interested in making to the H933 was to get it to the T-Mobile H932. The US998 doesn't really offer much of a difference over the H933 stock firmware. Then again, there is the possibility of if it would flash to the US998, that maybe it could then be flashed to the H932. With the Galaxy S9 Plus I have, that is what was needed to take my 965W. I had to flash 965U1 with a factory wipe to the device, then flash it again to the 965U T-Mobile firmware to get band 71 to appear in the *#2263# hidden LTE menu.

I only need one phone on T-Mobile right now though and the S9 Plus is what I am using. It is cheaper for me to get phones on the Canadian side thanks to my loyalty plan with Telus over T-Mobile in most cases. The H933 cost me nothing from Telus and the S9 Plus only cost me $380 Canadian Pesos after tax and crap. My Telus loyalty plan doesn't charge me any subsidy fees so the price is the same whether I get a new phone or not, so I may as well get new phones. :P
[LG V30 Guides, News, & Discussion] ChazzMatt:
What does storage show in Settings? That still shows 128GB, right? The only thing different about V30/V30+ is the internal storage. The back of your phone still shows V30+ and if internal memory shows 128GB, then only in "About Phone" is it different. Maybe AS998 doesn't have a V30+.
[LG V30 Guides, News, & Discussion] SeeZaar:
Long story short:

1. Phone: Originally i had LG V30+ LS998 Sprint nougat. Lunch LGUP press partition dl>choose as998 oreo>start>select all>flash and it works flawlessly. Now my phone name is just lg v30(thinq of course), but with all v30+ features, but i still didn't try to put sim card in my second SIM card slot to see does that one work. (Yes lgv30+ have two sim card slots, another is where sd card slot is) My IMEI, S/N ETC... Still the same.

Benefits: No any Sprint carrier bloatwares(apps), sprint longo or anything similar. Clean, fast LG just how I like. And faster 4G LTE speed.

Now i don't even have a need to root my phone.

My 2. Phone: Originally LG V30+ ls998 Sprint oreo. Lunc LGUP>partition dl>choose us998 nougat>start>select all>flash>doesn't wanna boot, keep restarting over and over. Put the phone back in download mode. Lunc LGUP>CHIPERASE>Then partition dl choose as998 oreo>start>select all>flash= works without problem, but my IMEI is totally different and i don't have serial number any more (if that is (S/N)). Ididn't try does it work with sim card. Should I try? Then i tried to Erase the chip again and install us998 on again, but it didn't work. All i got is this weird booloader screen so i put as998 again and it's working again.

Small correction: when u choose ChipErase option , u must choose kdz file anyway so after doing chiperase u don't need to do partition dl and install kdz file.

Btw: LG OCTOPLUS IS needed I THINQ:laugh: only for changing IMEI if is blacklisted.

I was wondering? Isn't the phone of incapable of flashing backwards like from Oreo to nougat. Maybe that why you ran into problems getting it to boot...
[LG V30 Guides, News, & Discussion] ChazzMatt:
No, what I meant was you said originally one of your LS998 had Oreo and the other didn't. Unless I read that wrong. You had two LS998 phones, one with Oreo and one with Nougat, right?

First you flashed the Nougat LS998 to Oreo AS998. Success.

Then you tried the Oreo LS998 to the Nougat US998. Failure. For some reason it wouldn't let you convert and downgrade OS at the same time? Something wasn't compatible.

But if you had reversed that -- Nougat to Nougat, Oreo to Oreo, I'm wondering if both would have been a success.
[LG V30 Guides, News, & Discussion] SeeZaar:
It wouldn't succeed anyway bc i did chiperase so i delete everything from the phone and i was still not able to install us998 on it

Usually it's the T-mobile guys who have issues the McAfee kill switch. I assume that's what it is... You're the first to have that problem with Frankenstein.

At this point you have flashed to US998 so you can't go back to LS998 (no KDZ), whereas the T-mobile guys can go back to their T-mobile KDZ and rip out the stupid McAfee.

Maybe try flashing US998 Nougat via REFURBISH? If it works, it will probably still be unstable and may still need Master Reset. If it works, thank [MENTION=2190582]mrsubway[/MENTION]:

Try flashing another KDZ, like AS998. THEN go to US998. I have that posted in the ROMs section.

Hoping someone here can help me... So I bought two excellent cond LS998 V30+ planning on carrier unlocking them to US998. After downloading all the required files I boot into download mode (Both phones are running LS99810a) Using the Partition DL I flash US99810d_01_0411.kdz All's well until I do step#3 Master Reset (post# 168) as soon as I let off the power button the screen blacks out and flashes a green android and I think it says "not connected" lower down... By doing the Master Reset button sequence I can get it back to the reset screen but I'm not able to "select" yes... The patched LGUP doesn't see any device for me to reflash or refurbish.... Thinking the first phone was just low on power or a fluke I carefully followed the instructions and bricked the second device!!!! Help!!!

Edit: I need to add that I successfully unlocked a LS998 a couple months ago and then found out it had a bad IMEI and returned it... So this isn't a strange process to me

Edit: I found out that by pressing the power button rapidly for about 15 sec suddenly gave me the reset options!!!! Yeah!! I'm making progress!!

[LG V30 Guides, News, & Discussion] ChazzMatt:
That behavior you describe sounds very much like the unstable Nougat US998 stage, before using Master Reset to stabilize and fix. Or trying to flash to Oreo US998 first without flashing Nougat first. Tell us EXACTLY the steps you've done.

You flashed to what firmware? Noguat -- what model, what version? Oreo -- what model, what version? US998?

And you tried the Master Reset instructions you quoted? Did you try Master Reset in between flashing Nougat US998/Oreo US998?

Master Reset is that specific set of actions you just quoted. It works if you're on the UNSTABLE Nougat US998 (before flashing Oreo US998), and you have to to do it before going on to Oreo from Nougat on the US998. Also can work to fix other situations.

You sure you followed all the steps? You

* flashed to Nougat US998 first via Partition DL (you can NOT skip this step!)

* THEN did a Master Reset (not a factory reset),

* then updated to Oreo US998?

(Some people can use upgrade for that last step, but others have to do full Partition DL again)

IF you already did all that, then either Master Reset again or use "refurbish" in LGUP mode to flash US998 20B -- or do all the Frankenstein steps again, starting with Nougat US998.

Yes, always.

If you flashed the TWRP-flashable zip, the instructions in the thread clearly say to reflash Magisk. You didn't read that? ;)

If you update via KDZ with LGUP, you have to UNcheck the recovery partitions to keep TWRP, then boot to TWRP, reflash the no root, no encryption files, as well as Magisk.

SO, easier to update via TWRP. Less steps, but in each you have to reflash Magisk.

I rarely write stuff in directions just to write stuff. If it's there, it's important.

(The exception may be my rant against phones like OnePlus and opinions about the V30, in the preface to the WTF INSTRUCTIONS -- but that's meant to be educational. You can't appreciate how "good" the V30 is unless you understand how "bad" -- what's missing -- other phones are.)

If you're already on Oreo, you just need to downgrade to Oreo 20A or 20B. No need to go back to Nougat.
