Good job!

Yes, use the other LGUP for the rest of the root procedure. But the newer one is recommended for anything to do with Pie.

Just follow the Part 1 steps in post #2.

Post #1 mentions unplugging the USB cable to interrupt flashing H933 after laf, which the OP later confirmed you don't need to do. I could have sworn he updated this in post #1 as well. I think an older version of that post may have been restored accidentally at some point.

Good luck (y)
I have succesfully gotten TWRP on the recovery partiton but i need to know if it is safe to update twrp from twrp on this device (becasue the pie stock flashable via Twrp lists a newer version)

Well done rooting your H932!

You should be OK to update to a later TWRP using TWRP. Certainly if it's a TWRP version listed in one of the stock H932 threads.

I no longer have my H932, and never went to Pie on it. Kept it on latest Oreo.

Hi there. I cannot for the life of me downgrade my lg from pie down to nougat like we're supposed in this tutorial. I get an error every time because I can't get the right DLL for LGUP. I'm really frustrated. I understand how to follow instructions but not for downgrading obviously. I've done it before on other phones so I don't see what the problem is? Would someone be able help me with this part before I throw my phone in the fire? I just wanna root this phone and I'm up to challenge, but I'm up against this brick wall right now. For something that seems so easy, it's just not working for me today.

Urk, i think i may have posted too soon because i think i figured it out by lgup dual mode and am currently booting nougat as i type this, yep, so easy a caveman can do it. Now onto the rest of this festivus!

Well, now im really stumped. I was sailing in part 2 and am in fwul. After first three lines of code i a whole bunch of lines that looks something is not working and I do not know what to do. I dont want do anything else until hopefully someone can help me with this. Here is shows up in terminal after the first three lines of code:

I read in this thread that someone else had the same problem, but i dont understand how they were gonna fix it. Im lost and I'm scared that phone is gonna be f**t now. I hope not.
Please, if someone could enlighten me on this issue asap i will forever indebted to you. Please please help me!

So I unplugged the device from my laptop and the phone is working. I just flashed pie on it again so I could have working phone. The bootloader is still unlocked, but I have know idea what to do now. I'm reading up around the internet to see my options. If I had of known that this phone would be such a pain I arse to modify, I wouldnot have bought it. I don't know what Im gonna do with it now. I would still like to obtain root on it of if I can figure it out, but I am seriously contemplating buying another phone again. One that is not not such a pain to modify. This is second time I bought an LG that had to be so whacky to play with, the latter being the G4 from Verizon. I gotta stop doin this to myself lol...

Glad you got this part figured out. It's really the easiest, compared to the rest necessary for the T-mobile H932.

Yeah, the T-mobile H932 is the hardest nut to crack of the V30 models. All the others can use the WTF method.

As you know the problem is T-mobile/LG put in totally different RSA encryption for this model ONLY -- of all the 2 dozen V30/V30+/V30S variants.

With what we know now, the only reason for someone to buy T-mobile H932 would be if they were a T-mobile customer and NEEDED LTE band 71. Even then, many T-mobile customers buy US998 or LS998 and convert to US998. (US998 firmware allows T-mobile VoLTE and Vo-WiFi.)

Even the Dev of this thread (who is a T-mobile customer) sold his T-mobile H932 to get the current OnePlus phone at the time -- quickly ditched it as crap, and came back to the V30. But the 2nd time, he bought a US998.

However, you CAN do it. This thread exists because it does work. Just takes patience!

Yeah didn't know that and obviously didn't do any homework. I'm from Canada and I bought this one used off of someone because I was walking around with a rotten Apple. I really have no idea what to do next but it's going to take a whole lot of learning it seems. I'm pretty sure I will just ditch this one and move on to something a lot more user friendly because this one hurts my brain. It's too bad because this really is a nice phone but can't be unleashed to its full potential so in a way it's broken to me. Thanks T-Mobile 🤬

Since I didn't actually achieve root yet, I do have a strange sort of problem. After my phone boots up and after the bootloader unlocked screen warning, it switches to a screen with a padlock with a spinning circle around it. And then the phone starts up and goes a verifying app rigmarole and then the phone seems normal after that. Does anyone know what that's about? It seems to be working fine so far but it has that little quirk at startup.

NOOO Don't ever take an OTA. You will need to flash an Oreo zip to get back. I am guessing there isn't one since there would be no need.

I don't have time to make one today unfortunately.

EDIT: and what?! you mean TMO finally has a locked bootloader on the G7 just like all other carriers? They didn't just strip fastboot flash, they removed oem unlock as well?

I got H932 with TWRP and Oreo installed, but this phone is locked to T-Mobile for me to unlock I have to put the phone in download mode, since there is TWRP installed how can I get back to download mode without messing things up? Because when I try to go into download mode it takes me back to TWRP.

You can unlock H932 using this method without any issues see this video


for that method to work I have to have download mode, since I followed your WTF V30 H932 guide I was able to root my phone, but I found that method later on that why I was asking to get the download mode back. Is there any way to get back the download mode without messing anything up? Since it's replaced with TWRP.

Go to the H932 20s thread (linked below) and fetch the StockLAF.zip file. Flashing that in TWRP should restore your Download mode. Of course make sure you have TWRP on recovery too before overwriting the one on laf.

Remember to thank weakNPCdotCom for creating these ZIPs :)

I got stumped for a few hours trying to get laf on the FWUL OS read my sd card. I re-formated the sd card, partitioned it many times, renamed the TWRP file, and redid all the steps two times with no luck. I have a 32gb card that I partitioned down to 512mb and is on fat16. I read the instructions over and over again and read many of the posts before posting mine. I don't know what's missing. Update: I swapped sd cards to no avail, renamed the twrp file to twrp.img (that's the file extension) and reflashed the phone a third time to see the same thing on FWUL.

Hi I got LG v30 is not rooted and OEM locked it's still locked so what happens I downgrade from Android 9 to Android 8 and once I do that phone's boot up fine, but it's stuck with that T-Mobile logo it would not pass that when I go back I can go back to download mode or I can go back to fast boot mode and if I want to I can also reflash at h93210d and it will stuck into the T-Mobile logo for a minute and then it will say Android is starting do not turn off phone and then it will go back to 98% and then he will restart again so I don't know what's going on with it

I can hear the T-Mobile chime and I can see the T-Mobile logo with the white background and then it will go back again I did try do hard reset and that did not help I don't know if the motherboard is done for a day or something else can be done to fix this thank you

boot the phone normally and see if your sd card can be seen inside the phone or not? I had an issue with V30 I bought and that v30 had broken sd card reader inside which failed to read the sd card no matter what I did
