brick

After fleshing LS988 to US988 DL Partition a have bricked my phone.

Power for 18 sec doesn't work.

Power and VlmDn in 10 sec restarts phone and shows "LG V30+..." but after 7-8 sec it shows green android for half sec. and switches off.

Power and PwrUp shows something for 0,1 sec and switches off.

Connecting to PC doesn't make anything.

Haw can I unbrick it?

No, that's how [MENTION=6158380]TxanMoe[/MENTION] permanently bricked his phone.

Well, he did it with H931 to US998 to H930DS, but same thing. North American variants seemingly aren't compatible with H930DS.

I have the LS988 Sprint Flashed To US988 can't factory reset data are nothing I have a blinking no command and I only have fastboot & download mode working I get no help from this
[LG V30 Guides, News, & Discussion] ChazzMatt:
If you flashed via DL Partition that wipes your data, so I don't understand. Plus you still have download mode, so you aren't really making sense. Let's go through this step by step.

1) Do a Master Reset? (the step between Nougat and Oreo). THAT will definitely clear all your data.

Master Reset -- using buttons:

1. Press and hold the Power and Volume down buttons.

2. When the LG logo appears and quickly release the Power button only and press Power button again but keep pressing the Volume down button until you see the screen to select Yes to erase and reset everything.

2) Also if you have download mode, just reflash KDZ. Use DL Partition. THAT will definitely clear your data, and you should have done that when flashing to US998, in the first step where you flashed Nougat US998 before upgrading to Oreo.

3) You say flashed to US998 but you don't say WHICH US998. Nougat, Oreo? Somewhere in between? Did you follow the instructions?

CONVERTING ANY NORTH AMERICA V30/V30+ (except T-mobile H932) TO US998 OREO

Yeah I did but I format the data in twrp so I get bootloops I was thinking about just flashing a rom but I'ma wait into I get the main part done first by me being a big head I don't read alot so my bad if I don't get it right in oh ls98821a thats what I was coming from
[LG V30 Guides, News, & Discussion] ChazzMatt:
OK, so if you have TWRP already, then you've actually completed all this Frankenstein process at least once.

In TWRP, you probably should have just flashed [MENTION=3642089]westwood24[/MENTION] US998 20D stock image. Or are you a Sprint user and need Sprint LTE bands?

Master Reset will definitely clear data. We also use it to stabilize/stop bootloops in the stage between US998 Nougat and Us998 Oreo.
[LG V30 Guides, News, & Discussion] Deandre7452:
Yeah I'ma Sprint user but I'm on Us998b Oreo I seen a flash twrp for that but should I just got back to download mode in update to Us998D then flash the lastest twrp.....the buttons keep going to fastboot nothing else

I can get the IMEI screen but thats about it
[LG V30 Guides, News, & Discussion] ChazzMatt:
Do a Master Reset.

Master Reset has nothing to do with seeing stock Recovery or has anything to do with stock Recovery. Read the instructions, if you don't know what a Master Reset is.

I have asked in an H933 thread but will ask here as it also applies and there are probably a lot more eyes here.

I have gone through this process but am wanting to return to stock H933 with a locked bootloader.

I have flashed H933 stock 20f and master reset but have lost Mobile data. I have gone through multiple steps including master reset, verified APN, mobile data on & no limits, correct mobile type connection setting, reset network settings, carrier reprovisioned, tested a working SIM in the device and no data... So it is something on my device and not the network. :( Also, the bootloader remains unlocked and I don't think fastboot is working on the H933, so I don't know how to relock it.

1. looking for help on getting data working again

2. looking for guidance on how to relock the bootloader for the H933. I'm thinking I might need to flash it back to H998, relock there then flash back?
[LG V30 Guides, News, & Discussion] ChazzMatt:
I've never relocked a bootloader in the past 8 years, so I wouldn't know.

I always unlock them. ;)

[LG V30 Guides, News, & Discussion] Mad Medik:
I have flashed back to US998 Nougat. My data connection returned. I have access to fastboot commands here so I can deal with the bootloader issue here.

Any thoughts on the loss of data access when going to H933?

I am downloading H933 Nougat and will flash to that and see if (for some reason) data works going that way. Then I can upgrade to Oreo from there.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, any North American V30 variant converted to carrier unlocked US998 can be used on T-Mobile.

You can also unlock the bootloader and root, using the WTF method if you wish. But if you just wish to have a carrier unlocked phone, you have that now.
[LG V30 Guides, News, & Discussion] ChazzMatt:
The loss of cellular data part is mystifying. You've converted everything back to H933, flashing ALL partitions (including modem), so you should have a fully working H933.
[LG V30 Guides, News, & Discussion] lost_:
So I bought a second US998 from the same seller, but he sent an LS998 instead.

However, I was able to frankenform it to US998 without ever flashing the Nougat KDZ. Instead, I LGUPped straight to US998 20B (DL Partition All), unlocked BL, and flashed TWRP. Once on TWRP, I then reformatted data, flashed the 20D zip, magisk, encrypt disabled and no root check. Everything looks stable. I put in T-Mobile SIM and got VoLTE + wifi calling.

Question: does the franken-US998 now support

the same exact set of LTE bands

as a true-US998, now that it has the US998 modem?
[LG V30 Guides, News, & Discussion] Mad Medik:
Issue resolved: I flashed H93320f (again) using DL partition. It rebooted into the new device setup. Without disconnecting, I selected refurbish and the same BIN file and went through again. It completed with a reboot into new device setup again but I had mobile data back. Credit to [MENTION=9452558]dapakhtun[/MENTION] over here for the idea.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Hmmm. You must have gotten lucky. Me and at least two other people could not do that on LS998.

Even when we found out the Verizon VS996 could do that (go straight to Oreo), I still wouldn't change the instructions.

That question has been answered over and over. Search the thread. It's also mentioned in the WTF thread.

If I follow the lineage os install guide will I mess anything else up here?

Can I simply follow this guide

Root then install lineage os

then just install magisk again after lineage os and continue to enjoy all of sprints bands?
[LG V30 Guides, News, & Discussion] ChazzMatt:
You don't say what V30 variant you wish to convert, but some North American V30 variants cannot install Lineage/AOSP ROMs, even when converted to US998 -- specifically H931 and H933.

You should start with WTF bootloader unlock and root thread instructions. If you need this Frankenstein conversion, the step where you need it will bring you back here.

If you have LS998 (since you mention Sprint), find the Sprint post-root thread to reflash Sprint modems.

ACTIVATE with Sprint first before converting your phone, unlocking bootloader, or anything like that.

Simple "upgrade" to US998 Oreo via dev patched LGUP. Hard part is already done, converting over to us998 Nougat.

See the Frankenstein thread for directions. Skip down to the part where you are just upgrading to Oreo.

https://xdaforums.com/showpost.php?p=76510671&postcount=168

Be cognizant that you want pre July 2018 Oreo firmware (20A or 20B) if you plan to unlock your bootloader. You can always update to latest firmware immediately after bootloader unlock and root.

If you don't care about bootloader unlock and root, then go ahead and upgrade to the latest -- which right now is 20E.

I cant seem to get lg up to recognize my ls998. I have the files to flash to us998 but I just cant get into the cross flash portion of this sprint root tutorial. Any advice on troubleshooting patched lg up would be greatly appreciated. I don't think I am "patching" it as directed. please advise. Thank you
[LG V30 Guides, News, & Discussion] ChazzMatt:
First, please go back and edit your post to REMOVE the entire LONG instructions post. We already know what it says. ;)

Second, you followed the directions, downloaded the dev patched LGUP, installed it where it's supposed to be installed? You went into download mode FIRST before opening dev patched LGUP?

You followed ALL the trouble shooting tips?

________

You posted over in the UPPERCUT thread about this issue, which confuses me. Uppercut has NOTHING to do with this V30 Frankenstein conversion and can conflict with dev patched LGUP. You need to uninstall Uppercut, if you have it installed.

In the Uppercut thread, you said you couldn't find the V30 driver. It's IN the dev patched LGUP. If for some reason you are having trouble downloading it, it's also attached to

post #1 of the US998 KDZ thread.

You NEED the US998 KDZ (20A or 20B) and you can download dev patched LGUP from there, if for some reason you can't download it from the instructions thread here.
[LG V30 Guides, News, & Discussion] alecthenice:
I did download the lg up files wrong. Will the files to flash be in patched lg up?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Dev Patched LGUP is a tool you will be using to flash the US998 Nougat KDZ and then later the US998 Oreo KDZ. Think of dev patched LGUP sort of like TWRP. You will be using it to flash OTHER stuff. The KDZ are sort of like ROMs. So, the same way you use TWRP to flash ROMs, you are using dev patched LGUP to flash KDZ -- first US998 Nougat, then master reset, then US998 Oreo KDZ (20a or 20b).

The links I show below -- the blue, underlined links -- are where to download the two KDZ you will need.

I'm quoting the instructions below. This is the "short" version. I then explain more about these steps further down in that same post, the same post you quoted.

In the instructions I also have screenshots to show what it looks like.

What what does the phone do when you try to go into download mode manually? Describe your manual download mode process. Some people think they're doing something the right way and then they realize they're pushing the wrong buttons. I've done it many times myself.

Looks like your phone is trying to go into download mode. You installed the lg drivers? LG Bridge? LG Bridge has a recovery mode which will download the stock kdz and attempt to recover your phone.

Did you try a different USB port? Different cable? Different computer? I had a similar issue with fastboot where it would not stay in fastboot and would just reboot itself. Had to try different combinations before i got it to work.

LG download mode

turn the phone completely off

while phone completely off

press and hold volume up

insert usbc cable connected to your computer with patched LGUP

Let go as soon as it goes into download mode

LGBridge - NOT VERIZON SOFTWARE

Download and install LG drivers and lg bridge form lg website or from links provided

with phone on and connected, make sure that phone is in photo usb mode

LGBridge recovery

Start LG Bridge and go to software tab, then recovery

Turn off phone

while phone completely off press and hold volume up

insert usb cable while holding button down until it gets into download mode

LGBridge should detect your phone and start recovery

And try a different usb port / computer / and cable.

If all of this doesn't work, you may have a bad usb port on your phone.

[LG V30 Guides, News, & Discussion] Alibaba0101:
I watched the whole video.

I saw you trying to use lgup, but you didn't do so using download mode on the phone. lgup requires download mode and must be used with the patched dll or the dll for your specific phone.

I couldn't see if your computer detected your phone or what drivers it was using. From the looks of it, you phone was on and not in download mode.

When you were trying download mode, you were using the verizon software and kept your finger on the volume up the whole time. What happens when you let go as soon as you see the download mode start? And use lgup or lgbridge recovery with the latest lg drivers?

Free help is worth just that, all i can do is try and give you some items to try. Take it for what its worth.

Did you try a different cable?

Did you try a different computer?

Did you try a different usb port on the computer?

Did you download the LG Bridge and LG Drivers?

so far none of these questions have been answered. If you have no interest in rooting and all you want to do is update the phone to oreo, then you should have no problem taking the phone to the verizon store and ask them to do the update for you.

[LG V30 Guides, News, & Discussion] Alibaba0101:
Can you connect your phone to the computer using the usb cable and does it detect it? If it does, provide a screenshot of which device drivers it's using in device manager. If you tried everything including a different cable computer port/computer, then it may just be a bad usb data port on the phone.

Or, if this a company owned phone or running IT policy/device management, they may be blocking updates or use of the usb port. I don't think any mobile device management can block download mode though.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Theoretically possible. However some people with real H933 once flashed to US998 had problems flashing back to native modem.

But LS998 has no problem flashing to US998. Your US998 if original (or possibly previously LS998) should work. If it doesn't, just flash back to. US998.

Before WTF, the Canadian H933, "regional carrier" AS998 and /open market US998 were the three most popular carrier unlocked models the Sprint LS998 and AT&T H931 were flashed to.

Because back then Frankenstein was really just for carrier unlocking.

When we saw an Canadian H933 V30+ (128GB), we knew something was up. Doesn't exist in real life -- only H933 64GB V30 was ever released. That's how we discovered online dealers were using Octopus boxes to convert V30 to other variants like H933 to carrier unlocked them.
