Oh I relocked the bootloader because I was going to sell the phone.

I'll give what you're suggesting a try.
[LG V30 Guides, News, & Discussion] dancarriv:
My luck, my son accidentally unplugged the phone while flashing. Now LGUP does not recognize any device...

I think this is it. I have a beautiful paper weight now.

Oh well...
[LG V30 Guides, News, & Discussion] cityneversleepz:
Did you try uninstalling and reinstalling LGUP and of course, rebooting the machine too.
[LG V30 Guides, News, & Discussion] MicroMod777:
Can you get to download mode?
[LG V30 Guides, News, & Discussion] dancarriv:
I can go to download mode, but LGUP doesn't recognize the phone.
[LG V30 Guides, News, & Discussion] MicroMod777:
Try another USB port, and then put in download mode 1st, then after 30 seconds or more open LGUP. If still not detected, try another pc.
[LG V30 Guides, News, & Discussion] RandomPooka:
And try another cable (higher quality is desirable) in all those places too. It could literally be any of those things, or a combination of them.

Well, its been a bit, but after a bunch of flashing (and some time away from the phone) there is one common issue with flashing North American firmware onto an H930DS: the modem.

While I did successfully flash both VS996 and US998 firmware onto the H930, I didn't look too closely at first. Flashing either of those leaves the phone in Service state: Radio off. This is why I could never get a signal or activate on VZW. I did activate on Fi, but there is no data (with H930 firmware). This is the same even if I run H930 firmware with different modems, no modem/radio off.

I have been through many "radio off" threads from the G3 up to the V30, but nothing I have read has helped. I tried zeroing out modemst1, etc but all that did was make me lose my IMEI for a bit. Hopefully I missed something else that is simple...

I'm tempted to just use chip erase while flashing US998 and then restoring my IMEI, etc but that might be a waste of time.

During this process I did learn what "Board DL" means in LGUP. Maybe it's known, but I haven't come across it yet. It is basically "Partition DL" with a factory reset. It does something slightly different, but the output flashes too quickly for me to fully read it. The effects seem to be the same. If you are going to immediately flash another firmware then it will save you from having to factory reset in between.
[LG V30 Guides, News, & Discussion] xaxxelous:
I should clarify: It's like Partition DL with select all. You don't get to choose partitions.

H931 TO BE CONVERTED TO US998

How far are you getting?

Did you install the Dev Patched LGUP correctly?

Does LGUP recognize the phone?

You need to go into Download mode manually BEFORE opening Dev Patched LGUP.

Many many people have used this method and it works.

Sprint LS998 V30+ and AT&T H931 V30 do not have publicly released updates. If you are not a Sprint or AT&T customer you will not ever have updates for your phone. Yes, dealers can use a code to carrier unlock an AT&T H931 to use on other carriers, but you will never receive updates. The solution is to convert to US998 -- which is carrier unlocked and has public updates you can install via LGUP software.

The key is you first have to downgrade to US998 Nougat, do a Master Reset (very important!), then you can update to US998 Oreo. US998 20h is the most recent Oreo firmware, and Pie is coming soon.

Usually problems with LG are solved by reinstalling drivers, changing cables, changing ports. Making sure LG up is installed correctly in first place.

Okay what about the next steps? What happens when you choose the kdz in the three dots menu and then choose partition DL and all partitions?

What happens when you choose the US998 kdz in the three dot menu from your PC folder, and then choose Partition DL and choose all partitions?

Does you see that choice in the LGUP window?

Look at screenshot #1 in the instructions. Does it look similar to that? The only difference is you should have US998 10D instead of US998 20A...

NEW STICKIES FOR NEWBIES

OK, the posts are now stickied. Thanks to the mods who helped.

Rather than a FAQ post -- which was suggested -- I wanted separate stickied posts that directly answer the two most common questions

* LS998 & H931 -- How to Update!

Has NOTHING to do with bootloader unlock or root, and happens now more with AT&T H931... But people buy either of these variants off eBay/Swappa but cannot update their phones because both Sprint and AT&T do not give updates to non-customers. That post directs you straight to the instructions for converting either variant to carrier unlocked US998, which DOES have publicly released updates they can easily install via LGUP. a.k.a. Frankenstein.

Yes, Frankenstein is ALSO used for most non-US998 North American phones during WTF, but that's a totally separate issue from just wanting updates for LS998 or US998. You do NOT need bootloader unlock and root just to get Android updates.

* ROOT YOUR V3O!

No matter what V30 variant you have, it can be rooted and that post will show you where to go.

How are these stickies helpful? Now when those questions are asked, we can just point to the sticky links instead of having to explain everything over and over. :p

I flashed nougat first, but my phone keeps rebooting like yours did. I did a factory reset. It won't stay on long enough for me to go to settings and enable developer options to turn on USB debugging. And lgup says no phone connected. What should I do to fix it?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Not factory reset. Master Reset.
[LG V30 Guides, News, & Discussion] :
I did the master reset. I said factory, but meant to say master reset
[LG V30 Guides, News, & Discussion] ChazzMatt:
Try it again? The Master Reset stabilizes Nougat. Then it won't keep rebooting. Then you can go into Settings, etc
[LG V30 Guides, News, & Discussion] :
I've did the master reset a few times, but no luck. Won't stay powered on long enough to get into the settings. FML. Update, I just got lgup to see my phone. I'm flashing it now.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Until you stabilize Nougat you won't be able to successfully flash Oreo...

If you can't Master Reset successfully for whatever reason -- tell me more how you're doing it? -- then try Board DL with Nougat instead of Partition DL. I've not used it myself, but here's recent post talking about it:
[LG V30 Guides, News, & Discussion] dancarriv:
I got my V30+ back from the dead. After fiddling with LGUP and trying multiple things, I just paid someone I found in eBay and they spent over two hours flashing and flashing and doing God knows what, but the phone is back alive, and was on Nougat. I have since upgraded to Oreo.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Congratulations!
[LG V30 Guides, News, & Discussion] xaxxelous:
If Board DL doesnt do it, don't forget that flashing nougat and then flashing nougat again in Refurb made all the difference for some of us where resets didn't work.

Also, I ashamedly admit I only went back a few pages to read your posts. Sorry if I missed something

---------- Post added at 20:30 ---------- Previous post was at 20:24 ----------

What method were they using to flash? JTAG or something like that?

Is it possible to share who helped you for others that might want/need it?
[LG V30 Guides, News, & Discussion] :
I finally got lgup to communicate with my phone in download mode. I had to run regular lgup, then I deleted lgup, model and logs and replaced them with patched lgup, and I didn't reboot my laptop, I just immediately ran patched lgup and it was able to communicate with my phone in download mode ? So I was able to fix it. BTW, I realized that I did accidentally flash Oreo instead of nougat, that's why I ran into that issue.
[LG V30 Guides, News, & Discussion] dancarriv:
I don't know if I can post their details here. They used JTAG, Octoplus software, and some other things I couldn't quite catch.

Look on eBay for "remote service unbrick LG G6 G5 V10 V20 V30 in Qualcomm mode 9008"

You will have to remove the back cover, disconnect the battery, and use the test point method to put the phone on 9008 mode. Then they connect to your computer via TeamViewer 14.

[LG V30 Guides, News, & Discussion] xaxxelous:
Thanks. I think I have seen that on ebay before, but your info helps.

I assume it would work if you put (or accidentally got) the phone in 9008 mode the old fashioned way? I.E. Flashing something bad.
[LG V30 Guides, News, & Discussion] dancarriv:
I played with cross flashing until my phone was in a boot loop to fastboot I couldn't get out of. So I opened it and put the phone in 9008 thinking that I could use QPST or QFIL. Since I was way out of my league, I just started searching and found those guys on eBay. Problem solved.

[LG V30 Guides, News, & Discussion] dancarriv:
Well, since my phone was back up and running, I inserted my SIM card from Bell Canada, and it was catching all bands that it was expected to catch. I didn't unlock the bootloader at that stage. I removed my SIM from Bell, and inserted my Freedom SIM (Freedom uses band 66 in Ontario). It wasn't seeing that band.

Still without unlocking the bootloader, I used LGUP to upgrade to Oreo (20a) and inserted my Freedom SIM. To my surprise, it was running on band 66 flawlessly. At that point I did a hard reset, and I set up the phone, entered my google account details, installed apps, etc. (no bootloader unlock). Next morning, the IMEI and all those codes had

dissapeared

.

So I did another hard reset after removing my google account and SIM. No IMEI.

Then:

- I downgraded to Nougat with LGUP - No IMEI (no sim inserted, on partition DL);

- I tried the same with Board DL - Still no IMEI (no SIM inserted);

- I had to run some errands and came back home in the evening. When I turned on the phone, IMEI was back!;

- I inserted the Freedom SIM, I entered my google account (did not install any apps), and upgraded to Oreo using 20b (to this point I had always used 20a); and

- The IMEI did not disappear this time, but the phone does not catch band 66 any longer.

I unlocked the bootloader and upgraded to 20h using LGUP, and I set up the phone without removing the Freedom SIM, but it does not connect to LTE via band 66, only bands 4 or 7.

Has anyone experienced this, where the IMEI disappears and then reappears out of nothing? And any thoughts on what could have happened that made me lose band 66?

Check out that link and be sure to read my inclusion at the end. I believe if you want to have the bands from freedom you're going to need to do as I've done with ChatR and dump your working radio.

If you already have then disregard of course.

As for your question I've only ever lost IMEI by cross flashing from H93310h to US99820h but obviously this whole procedure for all of us is wild lol
[LG V30 Guides, News, & Discussion] ChazzMatt:
You can also lose IMEI by doing Chip Erase in LGUP -- and it won't ever magically reappear... He didn't do that, so strange his IMEI disappeared by just doing a reset.

Anyone have a fix for when you forget to disable your pin before attempting this and can't get into the master reset mode after flashing us998 nougat? I'm out of ideas.

Can't find a way to flash back to LS998, and I am totally stuck at the LG logo. Only thing I can actually do is enter download mode.
[LG V30 Guides, News, & Discussion] ChazzMatt:
You can't flash back to LS998 -- until you have bootloader unlock and are rooted.

If you have download mode, that should be all you need. Maybe I'm misunderstanding something...

You don't "get into" master reset mode, you perform it. It's hardware base button pushes which is like a super duper factory reset. More powerful than factory reset. It will stabilize the wonky Nougat flash you had to do before flashing Oreo.

An alternative I've been told is to flash Board DL instead of Partition DL. Supposedly it's like Partition DL + Master Reset. But I've never done it myself.
[LG V30 Guides, News, & Discussion] cityneversleepz:
Did you try to hold the power button until the phone turns off? If it turns off, you should be able to master reset from there. If you can't turn it off, another possible way to get to master reset; hold the power button until the LG logo. Then press and hold volume down so that you're holding both during the logo. You have to be fast this way though. Now let go of power button for a half second and then hold it again.
[LG V30 Guides, News, & Discussion] nascar48:
There’s some security feature that prevents me from doing a master reset. So I get an error message doing that on the phone.

Also, can’t do a board dl with even the modded LGUP because it still sees it as a LS998 and pops up an error in LGUP because the mod must only be for partition DL.

So, I think my only option would be to find a ls998 .kdz and flash that using board dL, disable the pin security so the master reset works and do it again maybe??? But can’t find a ls998 .kdz anywhere.
[LG V30 Guides, News, & Discussion] ChazzMatt:

what do you mean by partition DL?

I'm trying to root an H931 (AT&T) and leave it on AT&T with H931 firmware. I gather I need to flash it to US99810d_01_0411.kdz, and then to US99820a_04_0330.kdz and then to H931 20H Flashable. I'm not clear at this point when and where I do the intermediate steps like new_unlock.bin or magisk or the like but right now I cant get past the first flash. I get Error 0x4, Not support cross model download H931 to US998. Tf I'm understanding these posts I'm stick sooner than most of you got the first flash OK but can't do the second. if any of this is wrong or even frighteningly wrong, I welcome a warning (or more) even if it reveals the depths of my ignorance.

i had been opening the download mode first

i kept getting wrong dll messages if I didn't do the download more first.

starting d/l mode first is the #1 troubleshooting step and I have been using that list., I might be missing something but I think I've done them all. It's a different computer and a clean install, several different cables (now using the charging cord that came with the phone) and i've tried the three ports on the laptop which seemed to work better than the desktop with 8 ports, I think I have the lgup files correct but arent sure of that. Aything I missed? i know you say that you just refer people back to that list. anything else? is it necessary to only have one dll file on the common folder?
[LG V30 Guides, News, & Discussion] Bob Simons:
maybe this is what I was doing wrong?

I was using or at least trying to use LGUP in upgrade mode. I'd read that “refurb” wiped the phone and “upgrade” preserved data and that “chiperase “would eat the IMEI and all that but I never caught the instructions to use the DL Partition (Partition DL?) was this a problem? I now see to try upgrade as another thing to try. So I was wrong to start 2wihgt upgrade, I gather?

Can you confirm the LGUP Patch instructions? Put the common dll file in the model\common folder and have only one dll file there? remove any present file if it isn’t overwritten buy the new one? The log file isn’t important, and is from the installer and can be ignored? Rename the old LGUP file and copy the new one or delete the old one or it doesn't matter? I'm only asking because of all the errors I’ve seen. I see a lot of people with similar questions and while the prevailing advice is to keep pushing on trying different cables and port and all that, I’m still unclear about the folder context. Are there multiple versions of the updated dll and consequently many are wrong?

Sorry to keep badgering but I don’t see what I’m doing wrong here.
[LG V30 Guides, News, & Discussion] Bob Simons:
just to be clear, I'm trying to use LGUP to flash US99810d_01_0411.kdz to a new H931 running v 7.1.2. The LGUP is the file named LGUP_Store_Frame_Ver_1_14_3.msi from the Frankenstein port #168. It has been patched with the file LGUP+V30DLL_PATCHED_(5).zip and the LGUP.exe file has replaced the file at C:\Program Files (x86)\LG Electronics\LGUP. The patch also contained a dll named LGUP_common.dll located at C:\Program Files (x86)\LG Electronics\LGUP\model\common\LGUP_common.dll. I've tried this on 3 computers, 2 win 10/64 and 1 laptop running 7-64.

Once LGUP starts, I uncheck the checkbox next to the file type and patch section in the lower part of the window. that makes a path field appear and I point to US99810d_01_0411.kdz. The instructions refer to a command named DL Partition which I don't find although I find a Partition. I'm concerned about a warning regarding ChipEArase and other options which essentially says “don’t ever do anything that I don’t tell you to do” here but there are two comments immediately following which say that using "Erase" worked so I try Erase. This fails with a not support cross model download error.

Is this expected because you can't do a model change as an upgrade? Am I to use the Partition DL option or refurbish?

Have I made a different mistake?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Bob, if you look at the screenshots at the bottom of the instructions you will see the different modes. Refurbish is the default. If you have Dev Patched LGUP (and you used it a few weeks ago when you bootloader unlocked and rooted your US998, so you should be familiar with it) you will also see Partition DL. Like this:

When you choose Partition DL, you will then see a box/window appear which has the Partitions you wish to overwrite. You will choose all. That window may be hidden behind other windows. I have screenshots of what it looks like. Please go look at the screenshots.

When you successfully overwrite all the partitions to convert to Nougat US998, your phone will be highly unstable until you Master Reset. Do NOT freak out, just Master Reset it. This is a necessary step to then upgrade to Oreo US998.

Please do not try Chip Erase. I will not help you get your IMEI back.
[LG V30 Guides, News, & Discussion] Bob Simons:
i promise you I will never go near chip erase.

Why would a rational person do that? trying to change the IMEI, with a misguided belief that it woiuld work out well if they tried? trying to get their calls billed to another party? Of just adventuristically trying things? I used to be very afraid of losing my IMEI in my Samsung days and I remember tryiung to back up the partition wiht the IMEI info and never feeling conifdent that the backuop was ever qany good. I'm not about to screw around with a chance of losing it.

Without his nudging, these instructions probably wouldn't exist. "Frankenstein" for V30 predates WTF bootloader unlock and is used to carrier unlock or convert to other North American V30 variants.

[Frankenstein Phone] Using LGUP for crossflashing

Now back to regularly scheduled programming...

Bob, posting this here. I'd really rather answer in the thread. I sometimes don't see Private Messages until days later and any answers can help others.

doing something wrong with LGUP, most likely DLL placement

Your basic plan is right for the H931.

The "not support cross model" error some people get initially but manage to overcome it. It's always reinstalling drivers, USB cords, different computer ports, going into Download mode first, etc.

I know you are using the cord that came with the phone. Just for fun, use another one. See if that makes a difference.

This has worked for thousands of people and will continue to work. We've had Frankenstein for a year now. (See post above.) If there was SOMETHING ELSE to write in the instructions I would, but the instructions are as complete as they can be. I even include screenshots at the bottom and trouble shooting tips.

For SOME PEOPLE installing the "regular" LGUP first then shows them where to replace the .dll properly. But you used Dev Patched LGUP before on your US998, so you should be very familiar with it.
[LG V30 Guides, News, & Discussion] Bob Simons:
tried 3 computers, lots of cables and lots of ports. I keep thinking that I'm not doing the patching correctly. Is there another DLL I should try? I've re flashed the LG drivers, reinstalled the LGUP, rechecked the dll, and set up 2 desktops and one laptop and grabbed several new Anker and stock cables. feeling dumb and frustrated. You say this is all that there is. Where could I think I was doing it right when I really wasn't? I'm thinking the DLL is the most likely place.

What are your thoughts?

And yes, I've rebooted two of the three computers.

Now I have an iMac. Is there some worthwhile magic that I should bother to set up the mac in this horror show?

You say to always make sure you're in download mode first but you suggest there's an alternative. is there an alternative and is it worth trying it??
