Wow. Being so sick has made me not think straight . I can't believe I didn't think about that since you have to flash back to 10d.

No pressure on the flashable. It isn't that big of deal for me or us but thanks for thinking about us with the extra work.

Hey Brian. I dont know if you saw my pm but im glad it works :P
[LG V30 Guides, News, & Discussion] runningnak3d:
[MENTION=4591212]me2151[/MENTION] No, sorry, my PM box is so backed up. I am going to have to spend some time this weekend going through it.

This isn't quite the same as lafsploit for the H918, but the concept came from research for that project.

Next tasks:

* Get Oreo and root working on the V20

* Get all other G6s root in addition to the H872

* Consider buying a V30 so I can help here as well :)

[LG V30 Guides, News, & Discussion] me2151:
Ah lol. My pm had jsut suggested taking a look into the h932 since its similar to the h918 in regards to bootloader. yea you should join us. I have my P rom working now. ill probably hold off on releasing it to the public though til i do more features. However. Only non stock rom to have enforcing on Joan :D

You stated, "You need to grab FWUL (version 2.7 or later) and burn it to a USB stick: link

Even if you have Linux, and you think you can install the dependencies, don't. I know this works from FWUL."

When I went to the page it has 2 options/2 types of FWUL... which should we download:

"Main Download Server:

persistent mode ( read FAQ #4 ): Latest version (click)

forgetful mode ( read FAQ #4 ): Latest version (click)"

I'm guessing Persistent mode version....?

Thanks

Feedback

I had a moment to go through the instructions as a "typical user", and am providing feedback to make this as painless as possible, crystal-clear, & hopefully prevent any bricks!: (Please correct any inaccuracies!!)

EVERYTHING should be said!!! Especially things that will brick our phones :) People like me that ARE extremely computer literate and have been 'custom rom-ing' for almost a decade still won't know all of these nuances. I've been just catching up on all of these advancements with the V30 and your latest discovery, read hundreds of posts, but I still won't pretend to know everything! And apparently a mistake like this could've made my phone gar-bosh. So don't underestimate peeps like me :) So: in Android phone settings->Developer Options: There are 2 checkbox(es) we need to select? "OEM Unlock" and "Fastboot OEM unlock"? (Im not sure about the latter mostly)

Link or steps if you're NOT? Ways to check? (I like many users will either get a random phone off ebay, or have one already, and won't know our baseline or how to determine this. & is this a deal breaker if it's not 10d?)

Link or steps if you're NOT? Does that link also contain the software or is there another link we need? (Again, if there's another link, version-mismatch might cause unpredictable results for some users)

Fat32: I've used SwissKnife https://swissknife.en.uptodown.com/windows to do easy FAT (same as FAT16) formatting. I say this because I already saw issues around this.

I'm looking to buy a V30 only since you figured this out :) Much thanks! I'll say that again, you're awesome & I'm jealous! It sounds like now ALL variants can get the bootloader unlocked and a custom recovery installed: H932 via this thread/method & all other variants via WTF exploit (Again, please keep me honest!). (I just want to double-check my info so I (& others) buy a phone that will be able to get a custom ROM & plan to get the H932 and will report back if/when I get band 71 working for those interested.

I know some of you that have been in this since the beginning are thinking, come on man, read the posts! Like I said, I have been for over a week. There are thousands of posts, and even if I/we read EVERYTHING, we still wouldn't be able to decipher the bad info from the good! ...so thanks for your patience :) I'll post more once I actually try this. And thanks again Brian!! Really awesome...

---------- Post added at 03:07 PM ---------- Previous post was at 03:01 PM ----------

Umm... For all of us that use this and get it working, I think we should do donations until Brian can get a free V30, eh?!? (Can't yall read between the lines :) ) Besides, think of all the additional support you'll get if he actually has a phone to test with!! haha

[MENTION=3270051]igotroot[/MENTION]

Did you get it working yet? If not I can run you through the hardest part of it. Also, choose the persistent FWUL. Basically persistent mode means it saves your data when you leave. It's just easier that way
[LG V30 Guides, News, & Discussion] runningnak3d:
If you just want stock v20k, then there is a link in the first post to a "quick a dirty" ROM I threw together. You MUST flash Magisk again after flashing it, or you will lose TWRP again.

[LG V30 Guides, News, & Discussion] runningnak3d:
First post updated with credits to [MENTION=5497494]R800x_user[/MENTION] for the use of his phone to make this happen. I *MIGHT* have been able to pull it off without a phone to test with, but the fact that he loaned me his phone -- understanding that I *MIGHT* brick it -- was just awesome, and definitely made the process much easier on me.

Massive kudos dude!

[LG V30 Guides, News, & Discussion] KUSOsan:
It gets pretty bad if it exists. On the V20 only certain models had it. But yeah it'll end up making the phone start lagging to the point where it feels like TouchWiz on the older Samsung's. Mine got pretty bad.
[LG V30 Guides, News, & Discussion] inuyasha1999:
Can't wait to try again after I get my phone back from LG or replacement phone (whichever they end up doing). I somehow managed to brick mine a few days ago while trying to do the H933 laf flash/H932 flash - laf. Ended up with my phone only being able to boot to fastboot mode :(. As per Brian, this might as well be a 9008 brick. Phone should be on its way to LG today, and will hopefully have it back, or a replacement, next week (I'm in Texas where their facility is).
[LG V30 Guides, News, & Discussion] K-alz:
Has anyone found out how to get download mode back? Mine is gone. I'm willing to mail you my phone, Brian. So you can make a video and at the same time root it for me lol

[LG V30 Guides, News, & Discussion] K-alz:

[LG V30 Guides, News, & Discussion] runningnak3d:
What version are you on? If you are on 20k then you will have to find a kind soul that is either still on 20d, or is willing to flash back to 20d so they can get your the update.zip. They have to be rooted, otherwise they don't have access to the directory that it is stored in.

[LG V30 Guides, News, & Discussion] K-alz:
20K. You heard the man, guys. Help a brother out. lol
[LG V30 Guides, News, & Discussion] Septembersrain:
[ROOT] H932 - lafploit 1.5 up to v20k (but you MUST downgrade to v10d)

LOL! I saw the erase data screen but held the buttons too long. Tried again 5 more times. I'm just going to move back to stock. It's all good. Haha.

By the way, Make sure to update to Oreo before you relock your bootloader if you decide to go my route. Sorry guys!

From Brian-

You have to be SURE that TWRP isn't on your phone before you lock your bootloader. If you lock your bootloader, and laf, boot, or recovery are modified, you will get that warning screen that you get when your bootloader is unlocked (the yellow one), only this one will be RED and your phone will not boot, and you have no way to unlock your bootloader.

Lastly, if you never rooted, you definitely have H933 laf still on your phone (unless you have taken an OTA), and that IS a modified partition, so you will have the RED warning, and be stuck.

Bottom line, take an OTA before you lock your bootloader.
[LG V30 Guides, News, & Discussion] SweetwaterBurns:
I'm probably going to be doing this tonight. If no one beats me to it, I'll try to grab the update.zip after downgrading. In what directory is that typically located?
[LG V30 Guides, News, & Discussion] runningnak3d:
Once your phone is rooted, and you have booted into the OS, check for updates, and once it has finished downloading:

adb shell
su
cd /
find . -type d -name "/proc" -prune -o -type f -name update.zip -print

That will give you the path to update.zip. You can then adb pull it, or use a root explorer on your phone. Either way, you definitely want to delete it after you copy it off.

Now when I try to go back to download mode, and I did not quite enter at the end, I ended up restarting the device, I am looking for infor but I can not find much to help me, you know what happened?

I try to flash a rom with lgup, but the program also fails to enter download mode.

I already tried the ADB mode "adb reboot download" and I am not logging in either.

Edit : install android 8 via twrp, then install android 9 via twrp and that's when i had the problem.
[LG V30 Guides, News, & Discussion] TheDannemand:
Use TWRP to flash H932 laf (I suggest the one from weakNPCdotCom's 20s thread). That will restore download mode.

At this point you want to flash ROMs (and other things) primarily with TWRP. Download mode is your fallback option.
[LG V30 Guides, News, & Discussion] ChazzMatt:
As [MENTION=832590]TheDannemand[/MENTION] said, you will flash any ROMs in TWRP.

But, you need to go back to last Oreo 20S TWRP flashable zip, IF you want LOS/AOSP custom ROMs. Any custom LOS/AOSP ROMs the T-mobile H932 can flash will need last Android 8 (Oreo). LOS-16 ROMs need blobs (drivers) from LG stock Oreo/Android 8.

There are no LOS-17 ROMs yet compatible with T-mobile H932.

See this post, in THIS thread:

LOS Custom ROMs for T-mobile H932

https://xdaforums.com/showpost.php?p=82736509&postcount=1935

[MENTION=2022267]ShapeShifter499[/MENTION] is keeping LOS-16 updated for all V30 variants, but especially for the T-mobile H932.
[LG V30 Guides, News, & Discussion] l3dson:
or god now I notice that I lost the twrp !!!!!!!

Now what the hell? Nothing can be done ? :mad::crying:
[LG V30 Guides, News, & Discussion] TheDannemand:
Yeah, I bet if you flashed Pie with LGUP that caused it. Do you still have a working OS? If so, you can salvage this. But you have to be VERY careful at this point: H932 is a 3-legged stool: OS, Download mode, TWRP. As long as you have one of these, you can recover. If you lose all three, it's over. (US998, H930 etc have an extra leg in the form of a useful Fastboot. And all V30 models except H932 have an emergency spare in the form of a firehose for 9008 mode.)

1) If you have working OS with root, you can use dd (ADB) to flash TWRP to recovery and go from there. I don't remember the exact commands in my head, and don't have time to dig them out. But look around and you will find them. (Edit: Commands are here.)

2) If you have working OS, but NO root, and you are NOT on the latest Android version, you can take the OTA update offered to you, which will restore Download mode (even if the update doesn't complete). Keep shifting the phone's date forward by a few days to trigger the update offer.

3) If you have working OS, but NO root, and you ARE already on the latest Android version, you can use LGUP in FOTA mode to force an update, which will restore Download mode (even if the update doesn't complete). You need to get hold of the OTA file for your OS version. Look back in this thread about a year (+/- a few months) and you will find discussion of this. Several references to it later, but I don't have time to find them now. (Edit: Discussion of this is here.)

4) You can also try LG Bridge, which DOES work with H932 (it doesn't work with all V30 models) and has a Repair mode on the Update tab. Some people reported it required working Download mode (which you don't have) others reported that it didn't.

If you have neither of these, you are probably toast. Sorry to say.

Afraid I am out of time until Sunday. Read a lot, try only a little. Fingers crossed for you :fingers-crossed:

Edit: As a last resort, reach out to XDA member [MENTION=8187877]motogvasyag[/MENTION] and ask if he can help (for a fee). He has an Octoplus box, which didn't use to have H932 firehose, but maybe they got one since.
[LG V30 Guides, News, & Discussion] l3dson:
thanks man for your time but with some of the steps I could not recover the download mode, if I have the operating system on android 9 only I lost the download mode and the recovery, but well the other.

unfortunately you cannot recover it with the OTA update due to an error that I could not find on the web.

I think I will have to stay like this.
[LG V30 Guides, News, & Discussion] TheDannemand:
(For some reason I am unable to view your screenshot, both in XDA app and in PC Chrome)

I am sorry that it has come to this. You were doing so well recovering and getting root back. Once again, H932 is a sensitive creature, not forgiving of even small mistakes.

If you haven't yet tried LG Bridge, I would definitely do so.

As for using LGUP FOTA mode, it DOESN'T require working Download mode, it works inside the OS. But you need the OTA file for Pie. Old Oreo OTA files won't do since you are already on Pie. Others have been looking for that Pie OTA, and I haven't seen it posted yet. But you can keep looking for that. If you find it, I think flashing that in LGUP FOTA mode WILL fix your Download mode.

Until then, at least you have a working OS. And of course if LG and TMO miraculously decide to push another OTA, you are golden :)
[LG V30 Guides, News, & Discussion] Paintedstars:
Could anyone offer advice? I've been working on this root for the last couple of days and I'm at the final steps but there's an issue.

I install TWRP with fwul and after pressing yes twice android reboots, but it's stuck in fastboot. I can try to restart but it always goes from v30 screen quickly to fastboot, no TWRP.

I looked into advice about flashing my SD to FAT16 and that hasn't worked either.
[LG V30 Guides, News, & Discussion] TheDannemand:
Yes, create a small FAT16 partition on your SD card, then verify FWUL can read it. See the commands for that posted here in the last 1-2 weeks.

If you are currently unable to boot OS, and you don't have TWRP, but you have Download mode, that means you're just one misstep from a total brick.

I would suggest starting over, LGUP Partition DL back to 10d. If you've ever been on Pie, use the latest Dev patched LGUP for this step (from one of ChazzMatt's threads). Then completely uninstall that version of LGUP and switch to the one from post #1 for the remaining steps. (The LGUP link in post #1 doesn't work anymore. There's a link to a copy on my Gdrive in the last few pages.)

We have a treat for those who lost Download mode while on Pie -- and who don't have TWRP or a rooted OS with which to re-flash it, but who still have a working stock-like OS. Member [MENTION=2234254]tbxn[/MENTION] managed to capture the H932 Pie OTA file and shared the URL with us. In many cases this now makes it possible to restore Download mode.

The OP is no longer active here. I shared a copy of it on my Gdrive and posted the link several times in the thread. Look back the last few pages, or search for posts from me, you'll find it.

Edit: My copy of the LGUP from post #1 can be downloaded here.
[LG V30 Guides, News, & Discussion] AntwonTheDamaja:
Thanks, I found it, but I still have a question.

In the OP he says

I'm above 10d, but he says the link for 10d is below. The first link is H932 10d, region is USA, but it's above where he wrote that, and the second link is for the H933 10h and the region is Canadian (below where he wrote that). Is the guide just formatted poorly? Which one do I downgrade my phone with?
[LG V30 Guides, News, & Discussion] ChazzMatt:
He first wrote the directions as one LONG post and people with reading comprehension issues got confused. So he then broke it down into "chapters". He may not have rearranged everything in doing that.

You NEED to be on T-Mobile H932 Nougat for this exploit to work. So putting it above makes sense, even if he originally may have said "below".

The Canadian H933 Nougat is very dangerous. You will only use it to flash one particular partition (LAF) and even then ONLY after you've bootloader unlocked your phone. You will NEVER cross flash firmware from another V30 variant over T-Mobile H932, after this one very narrow exception this one time.
[LG V30 Guides, News, & Discussion] AntwonTheDamaja:
Hey, thanks for the speedy response. I have successfully rooted my V30, and I have only one more question. I hear that Oreo has better battery life, so I kinda wanna upgrade back to Oreo. My only question is that the zip file that OP told us to download to get Oreo back on your phone, where do you install it from? TWRP? And how do you suggest I get it onto my phone if there are file size limitations? Thanks much!

Hi, I don't know if you still monitor this thread, but I was doing this method and on part 1 I got caught in a bootloop.

It occurred after flashing only laf and I made sure to follow the instructions to the letter. Can't even boot into recovery now. Any hope or is the phone done?
[LG V30 Guides, News, & Discussion] mattgyver:
Are you ABSOLUTELY sure you chose the right kdz to choose the right laf? I can guarantee that if you followed the instructions 100% then it should have worked. I've beat my H932 up heavily with the number of times I've unrooted and rerooted since runningnak3d released these instructions.
[LG V30 Guides, News, & Discussion] TheDannemand:
:)

Some users in the thread reported that the version of LGUP made a difference, particularly after coming back from Pie. That's is why we recommend the following:

* If you've ever been on Pie, use the latest Dual Mode Dev Patched LGUP from one of ChazzMatt's Pie threads to roll back to to H932 Nougat 10d. After this, completely uninstall this LGUP and restart Windows.

* For the remaining steps of the root procedure, use the LGUP in post #1. Unfortunately that link is now dead, but several members have shared copies (myself included). Scan back a few pages and you will see the links.

Edit: My copy of the LGUP from post #1 can be downloaded from the link below

LGUP for H932 lafsploit root

https://drive.google.com/file/d/1TNbA4dDGmnnZyNhRamFpvvzWlvH8ir6K/view?usp=sharing

As for your current predicament, I can think of the following:

1) Did you unlock the bootloader first? Otherwise it *may* not be too late: Power off (if necessary, hold VolDown and Power for 8 secs). Then Hold VolDown while plugging in the cable. Now follow the bootloader unlocking steps from post #1.

2) It sounds like you've already been trying perform a Master Reset, but otherwise try that: Power off (if necessary, hold VolDown and Power for 8 secs). Then perform the Button Dance: With phone off, hold VolDown & Power until you see LG screen, then quickly toggle the power button, but keep VolDown pressed throughout. That should get you to the Factory Reset menu.

3) Get back into Download mode and re-flash Nougat 10d. Power off phone. Then Hold VolDown while plugging in the cable. Assuming you get Download mode, use the latest Dual Mode Dev Patched LGUP to flash H932 Nougat 10d using Partition DL mode.

That's all I can think of. I hope you are able to salvage your phone. Either way, please post your findings here :)

Hey Matt,

We could save users some trouble (and ourselves a lot of time) if you could insert a Mod note in post #1 containing the following:

* A working download link for the original LGUP. I think you already have it, otherwise see the copy I shared above.

* Point out about the need to use the latest Dual Mode LGUP to roll back Nougat 10d if the phone has been on Pie, BUT then switching to the original LGUP for the remaining lafsploit steps. I wish I could point to the posts now where members reported this to make a difference...

* Point to the lglaf command in FWUL to verify that laf can read the SD card. I last posted about it here.

* Point to weakNPCdotCom's latest TWRP flashable ROM threads: Oreo 20s and Pie 30d respectively.

I think that would cover the advise we mostly keep having to repeat in this thread. But of course include any others you can think of. (@ChazzMatt please any thoughts you may have as well.)
