It seems I have lost TWRP on laf at some point. When I tried to boot into it by powering the phone off, holding power up and plugging the phone in, it went into the regular download mode. I don't know if the 20o update set it back or what. But if I want TWRP on laf again, do I need to go through the whole FWUL thing again? Or just use the following instructions again in a normal command prompt in Windows?

If you would like a second copy of TWRP on your laf partition (I *highly* recommend this), follow these instructions:

-Download the version of TWRP that you want to install onto laf.

-Rename it to twrp.img

-Boot your phone to TWRP, and connect it to your PC

-Open a command prompt where you downloaded TWRP and type:

--adb push twrp.img /sdcard/

--adb shell dd if=/sdcard/twrp.img of=/dev/block/bootdevice/by-name/laf
[LG V30 Guides, News, & Discussion] inuyasha1999:
If you're still rooted, then you should just need to run through the process you quoted there. You should only have to run through the whole process again if you didn't flash Magisk again after flashing the 20o zip.
[LG V30 Guides, News, & Discussion] seadersn:
btw: with recent twrp versions diskdump (dd) isn't needed, the laf partition is backupable and flashable from within twrp. select image flashing, select your twrp image and select laf partition to flash onto. done. :highfive:
[LG V30 Guides, News, & Discussion] igorya79:
I have no antivirus, there is no firewall.

I did this procedure on two different computers

I wrote FWUL on two different media.

I formatted the card FAT and FAT32

On a 2GB card I have:

twrp.img (TWRP-3.2.3-6a-IntSD)

lg-rctd-disabler-1.0.zip

no-verity-opt-encrypt-6.0.zip

Magisk-v17.1.zip

what other conditions need to be met, to remove the problem: factory data reset is disabled by kill switch
[LG V30 Guides, News, & Discussion] Josh McGrath:
McAfee likes to A: stay on the device after uninstall and B: is also on the phone from OEM albeit a small version.

So, check device admins and disable that if McAfee is still there.

It truly is a garbage app. Oh and it's a security app, yet you can't use special characters for passwords...
[LG V30 Guides, News, & Discussion] ChazzMatt:
Then get rid of the kill switch. ;) UNINSTALL malware/bloatware McAfee.

UNINSTALL McAfee app.

It's on the phone.

It's what's causing your kill switch.
[LG V30 Guides, News, & Discussion] igorya79:
I reset to factory settings, after that I did not connect the phone to the Internet, and I checked all existing applications, including system applications - I did not find McAfee
[LG V30 Guides, News, & Discussion] Josh McGrath:
Check your device admins still
[LG V30 Guides, News, & Discussion] igorya79:
still not find
[LG V30 Guides, News, & Discussion] Josh McGrath:
I'd say just start over. Go to download mode and flash 10d and just go from that point on. That should bypass any locks and put you back 100pct stock
[LG V30 Guides, News, & Discussion] igorya79:
I did it - to no avail.

Can I flash a lower firmware version? to root her ...
[LG V30 Guides, News, & Discussion] Josh McGrath:
What was your error?
[LG V30 Guides, News, & Discussion] igorya79:
no error!

All process goes without problems.

but can't get into TWRP

When the LG logo appears, immediately release power (and ONLY power) and then immediately hold power again

- At this stage, the message appears: factory data reset is disabled by kill switch

and after that the phone is loaded into android and works as usual
[LG V30 Guides, News, & Discussion] Josh McGrath:
There is no possible way for any apps whatsever to survive an official kdz flash, not on internal storage nothing! Take out your sd card if you even have one in there?? At this point I'd just call tmo and have them swap it out.

[MENTION=5871700]igorya79[/MENTION]79

Do me a favor and check your FRP lock, LGs and also Google's in your phone and report back plz. You'll probably have to set up the phone all over again to check
[LG V30 Guides, News, & Discussion] TheDannemand:
I always delete my Google account first (Android Settings-General-Accounts) if I'm going to factory reset outside of Android's Reset menu. That disables Factory Reset Protection. I don't know if it also pacifies this McAfee thing as I don't have that. But worth a try, if you haven't already.
[LG V30 Guides, News, & Discussion] adamjrod:
I followed the steps and was fine until the phone was bricked and will not turn on at all.

I had just completed step 1, did the second partition and was moving on to FWUL. Now the phone is just BLACK AND WILL NOT TURN ON.

Any thoughts?
[LG V30 Guides, News, & Discussion] mattgyver:
Are you sure that when you did step 1, you had ONLY the laf partition checked for the h933 kdz? And then you chose the h932 kdz and checked everything BUT laf?

I'm pretty sure there was at least one person on here that accidentally chose either more than just laf on the h933 kdz, or chose the h933 laf on the second lgup flashing. Either way, that would brick the device.
[LG V30 Guides, News, & Discussion] adamjrod:
Sh*t!

Well is there anyway to unbrick?

Not to complain, but in that step, I would like BOLDFACE WARNING THIS IS THE KEY THING TO CHECK because those file names are easy to mixup. But thats just me.
[LG V30 Guides, News, & Discussion] mattgyver:
Not that I'm aware of. But I haven't been around these parts much since getting the "promotion" to forum mod and being assigned to other XDA areas. I don't know if there is a solution, outside of taking it to a TMobile shop or creating a service ticket for replacement with LG/TMobile.

As for the steps, boldfaced or not, H933 will still look like H932. It's the responsibility of the user doing the flashing to be 100% sure what they're choosing during each step. The laf may be something that can go between models, but the important ones are specific, especially when it comes to the unique RSA signature for the H932..

I could be wrong, but that's what I remember from when this all first came about.
[LG V30 Guides, News, & Discussion] igorya79:
Hi guys, I still can not overcome this problem:

I made a complete reset

I closed the bootloader

I flashed a full stock

no accounts or junk apps are installed in the phone - but I still can't get the factory reset screen

how is this possible?
[LG V30 Guides, News, & Discussion] TheDannemand:
Clearly Factory Reset Protection is enabled, and the way to disable it is by removing your Google account - which you say isn't currently there.

Let's get the normal stuff working now (i.e. resetting from inside the OS with FRP enabled) before getting to the abnormal (i.e. Master Reset, partition wipes etc).

Are you able to add your Google account in Android Settings-General-Accounts? If so, do it. Then run a Factory Reset from the Android Settings menu.

Assuming that succeeds, boot back into Android and add your account again. Reboot. Then delete your account. This should disable FRP so that you can now (hopefully) perform Master Reset outside the OS.

There is also an engineering/service menu reset which may do the trick. I forget the dialer code for it, but I can find it if the above doesn't work.

Edit: Obviously the Google account you add must be the last account that was used on the phone. If you don't have that account, then FRP is really doing what it was supposed to do: Prevent the phone from being used by someone other than its (presumed) legitimate owner. If the phone was bought used and the previous owner performed a Master Reset without deleting his/her Google account, that would trigger FRP.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Here's a screenshot of the instructions. It clearly tells where dev patched LGUP needs to be installed. ;)

It even clearly says you can't just unzip it "anywhere".

Please PRINT OUT the instructions before starting this.
[LG V30 Guides, News, & Discussion] Septembersrain:
Finally found LGUP the original. Downloaded. Deleted all content in folder. Now I'm back on Nougat.

Here comes the fun part. I probably can't get much further than the first part as I have no idea how to run FWUL. Also need to find an SD card and USB stick. What size stick and USB card should I need?
[LG V30 Guides, News, & Discussion] runningnak3d:
You only need a 64meg (yes Meg not gig)SD card, just big enough to hold TWRP and Magisk, but anything larger will work as long as it is formatted FAT.

For USB, you need at least a 4 gig stick, and 8 is better.

It's saying reboot countdown right after LAF, should I cut it before that?

Okay. So it restarted but it restarted fine after that. Next step.

[LG V30 Guides, News, & Discussion] Josh McGrath:
I used the included in Windows tool Diskpart to make a 500mb FAT16 partition in my 200gb SD card and then changed it back afterwards. So you can even do that.

If you're on Windows 10, you'll have to hold down SHIFT and then click on shutdown while still holding shift till the PC powers off. If you don't it won't boot into the FWUL USB stick and will keep booting into windows. Also you might have to set it up to boot in bios (if it's even bios on your PC anymore) if you need help let us know.

---------- Post added at 11:24 PM ---------- Previous post was at 11:21 PM ----------

Edit to your edit: if youre back to 10d, now select the 933 and ****ONLY SELECT LAF!!!*** under partition download. After you see LAF get done and it moves to something else, I think GPT, pull the USB cord. It doesn't matter what else gets written, just don't let it finish.

Then flash the h93210d again, flashing everything except LAF and let it finish.

These steps are assuming you were updated already past 10d

[ROOT] H932 - lafploit 1.5 up to v20k (but you MUST downgrade to v10d)

Husband will be home soon. He's better with computers. I'm more the jump in type with phones. Need to find a spare stick and SD.

I did that. Software still says H93210d. What should it say? I did all the steps with just LAF on 933. Then did the 932 without LAF.
[LG V30 Guides, News, & Discussion] Josh McGrath:
It will say that still since it's only LAF that's been changed. The dangerous part is over now ?
[LG V30 Guides, News, & Discussion] Septembersrain:
I pulled it when it was flashing 100% complete on the LAF with 933. Should I have waited until it tried to move on to the next?
[LG V30 Guides, News, & Discussion] runningnak3d:
Whoa, so you let it restart while you were flashing H933?

If that is the case, then none of the partitions that get flashed are RSA signed, and there is ZERO risk for this process.

Need verification on wether or not you let it restart while flashing the H933 KDZ.

The factory reset screen, to get to TWRP, is that only that one time, to flash magisk, at which point recovery-from-boot.p gets removed? I'm just curious if that is the only way to get to TWRP after everything is done.
[LG V30 Guides, News, & Discussion] Josh McGrath:
This is crazy. You either got really lucky that nothing major was flashed with an rsa sig or else there's no rsa verification on this and no risk as [MENTION=3167089]runningnak3d[/MENTION] said.

You weren't supposed to let it get to 100pct when flashing with the 933 kdz. I think mine finished flashing at 11pct after laf and I pulled the cable

---------- Post added at 12:12 AM ---------- Previous post was at 12:10 AM ----------

That's the only way to get to TWRP at first cause if it boots up it'll erase TWRP. After that adb reboot recovery or an app works perfectly

---------- Post added at 12:16 AM ---------- Previous post was at 12:12 AM ----------

You can't. You may get lucky and get the OTA to Oreo like I did which brought back download mode for me. So if it will let you, and you're on nougat, do the OTA to Oreo then try. But remember, that's your last shot so don't forget to flash magisk too or you'll lose twrp
[LG V30 Guides, News, & Discussion] Septembersrain:
I'm running the V30+. Still came up after going to the H932 and flashing everything but LAF. Works fine. Still can access the download mode too.

[LG V30 Guides, News, & Discussion] runningnak3d:
After watching the video in HD, the partitions that are changed are: cache, OP, and userdata. There is zero risk to this procedure. You can let the H933 KDZ flash those 3 additional partitions without problems.

I will update the first post. Pulling the cable is optional.

Zero risk of bricking your phone.

The OP links to this thread for TWRP

https://xdaforums.com/lg-v30/development/recovery-twrp-3-2-3-0-time-date-incl-t3852402

This wasn't the case when I first rooted. I think it was an old version of TWRP back then. I want to update my TWRP. So my question is, which one is everyone using? I see a DataIMG and an IntSD version (not really understanding the differences). Is TWRP for LG V30 made for all models? So I don't have to worry about compatibility? I also want to flash on laf partition. Does either version matter? And I assume any future TWRP update in that thread are safe to flash for us H932 users as well? Thanks in advance.
[LG V30 Guides, News, & Discussion] seadersn:
regarding the different new versions: the idea behind these both versions is to add the possibility to include your internal storages (= /data/media) content in your backup. this is not included by default, but contains additional data from your android setup. like emails, bigger files from games or other apps which need additional data (like maps from navigation software), configurations for apps and system and more. this additional data is needed when you want to have a fully working restored rom with all settings and data.

there are two versions, both capable of including this data: DataIMG has default /data/media handling, but has an image backup function for userdata added. it writes a complete userdata partition image which is really big, like ~55gb. you need a more advanced filesystem on your external sdcard, that can handle such big files.

IntSD version has changed the handling of /data/media in twrp sources, /data/media/0 (0 = main user = you; other numbers/users are not included for privacy reasons) is included in data partition backups here. some big default folders are excluded from that (downloads, twrp, movies, music), means the data backup is much smaller in size, can be compressed and will fit on every external sdcards filesystem. you can even backup this on your internal sdcard (/data/media :D): that of course isn't possible with the data image function.

it's made for all joan models, there are no compatibility problems. it also has the ability to flash LAF partition with either an recovery or an LAF image. you can continue using the older version by SGCMarkus, there's no real reason to update, they both work. it's only both the newer versions have some additions and fixes: they are compiled from a newer branch (8.1 vs. 7.x), have a slightly updated kernel, time and date is recognized correctly, are capable of handling encrypted data and have the possibility to leave out lockscreen settings when restoring data backups. that's all :) and yes, it's safe :good:
[LG V30 Guides, News, & Discussion] ChazzMatt:
1) ALL "Joan" TWRP are compatible with all Joan phones. [MENTION=3138121]seadersn[/MENTION] took over TWRP development from [MENTION=3475147]SGCMarkus[/MENTION]. [MENTION=3475147]SGCMarkus[/MENTION] had TWO versions of TWRP -- more basic (what most people need) and very advanced for vendor partition, stuff like that. The "basic" version was what was used in WTF root thread, as well as here in this H932 root thread. It's what you used.

2) When [MENTION=3138121]seadersn[/MENTION] took over V30 (JOAN) TWRP development, I asked him to make one for the WTF thread that was UPDATED but just had functionality most people needed -- like the [MENTION=3475147]SGCMarkus[/MENTION] TWRP originally used here and in WTF. He has done that. This more basic version (see link below) is NOT posted in his TWRP thread -- because then he would have THREE versions, and everyone would be really confused. :rolleyes:

He just released a new version of this "basic" TWRP yesterday. It has everything I need -- this is what I use -- and is the "spiritual" successor to the TWRP you rooted with in this thread. The TWRP below is what I currently have posted in WTF for bootloader unlock and root. In my opinion, it's less "confusing" than the two more advanced versions posted in the TWRP thread. Your choice.

I thank [MENTION=3138121]seadersn[/MENTION] for giving us this:

TWRP 3.2.3-7 | JOAN V30

Thank you [MENTION=3138121]seadersn[/MENTION] and [MENTION=3250376]ChazzMatt[/MENTION] for the detailed explanations. The two linked in the OP are way more than what I need. I just need a basic one. The main reason I was looking to update was so I could flash the recovery to the laf partition right from TWRP. I don't know if the newest "basic version" has that option but I'll update it and if not, I'll go the old fashioned command prompt way. Thanks again.

I've got a strange issue. Pretty sure I am just doing something wrong, but I'm not 100% sure what. When it comes to the lafsploit stuff, when I go to boot into recovery, it does an actual factory reset instead of going into TWRP. I tried waiting after the first command, reflashed the kdz's, turning on debugging, etc. Not sure what else to try. My bootloader is unlocked and everything was flashed properly. The only difference is that I formatted an entire 16GB SD card to Fat32. Do I need to do 2G only as FAT32, FAT16, or is my setup fine? Thanks in advance!

So I just picked up one of these used, it's already on 20p, and I don't see the fastboot OEM unlock in developer options, and I can't get into fastboot mode. I'm assuming it's 20p, but it's totally possible I'm doing something wrong as well?

[LG V30 Guides, News, & Discussion] invert_nexus:
From what I just googled, this kill switch is a theft protection measure.

I'm not totally clear about all the particulars, I think that it might be initiated by both the phone itself and McAfee.

The phone's kill switch would be caused by not logging into the original Google account for the phone.

McAfee apparently requires a pin number and/or deregistering your device from the McAfee website. Probably requiring said pin number.

A pain in the ass, I suppose, but if it makes someone think twice about stealing your phone, then great.
[LG V30 Guides, News, & Discussion] akira022:
ok, something I don't understand. It says check OEM UNLOCK in developer options AND fastboot oem unlock.

My dev options just has oem unlock and my software version is H93210d. Thanks.
