[STOCK] [H932] [30d] [Pie] T-Mobile LG V30 Stock Collection

[Vuzeultra]

The way to uninstall Magisk -- like to install a new version -- is to flash the Magisk uninstall file in TWRP. Then install new version.

What was your purpose?

If you wanted to go back to full stock for some reason, not be rooted, not have TWRP custom recovery, you would flash the KDZ in Dev Patched LGUP.

You got into Download mode before opening up LGUP? That's the best way. Get into Download mode first, THEN open up Dev Patched LGUP.

Also are you using the Pie compatible Dev Patched LGUP? It's the one with the devset.bat file and you open from desktop shortcut. It's NOT the one where you had to replace the .dll file manually.

If you're not sure, uninstall the LGUP and reinstall the one from any Pie KDZ thread, even the T-Mobile H932 Pie KDZ thread.


If that doesn't do anything, then someone with T-Mobile H932 will have to help you. This variant doesn't have normal fastboot flash commands.

I appreciate the help and just tried this version installed correctly.
My device is recognized during the bootloop, reaches 4% in LGUP and then reboots into download mode. Once in download mode it is unrecognizable by the PC "ERROR open port 0x200, Port open error (COM3)" failing the installation.

The download mode on the phone looks very empty, it says "Now waiting for any connection" and never changes. Below that shows "Unknown B74" which seems in increase in number, and shows "Unknown / E / L / R0".

I'm trying to flash H93230d. My phone is never recognized in LGUP while in download mode, only in bootloop.

Any suggestions?

I'm sorry this has happened to you. You will probably need assistance from experienced users who own the T-mobile H932. @TheDannemand?

You possibly still have TWRP, but will need to do the hardware "button dance" to get to it. It can be tricky and takes eye-hand coordination. In the last step you are saying YES you want to wipe your phone, but IF you have TWRP it actually boots to TWRP.

Power off your phone
Hold vol down + power.
When the LG logo appears, immediately release power (and ONLY power) and then immediately hold power again until you get the the factory reset screen.
You never let go of vol down until the factory reset screen appears. Once it appears, you can release both buttons.
Choose yes twice by using the vol down key and power to select.

I just read up on this. That really is too bad that uninstalling Magisk borked your phone like that. I cannot say why, but goes to show how sensitive the H932 can be. But also that trusting the Magisk installer to do right on every possible phone can be risky business. Better to clean flash in TWRP.

Good advice from ChazzMatt: Unless LGUP already overwrote TWRP during that partial flash, I think it's likely that TWRP is still there. And Button Dance is how to access it. I personally don't find it difficult at all, but many people do.

Alternatively you could boot into fastboot (PowerOff, hold VolDown while plugging in cable) then use the command fastboot reboot recovery. I believe that works on H932, although I am not sure.

I know you wanted to unroot, which is fine. But do NOT re-lock the bootloader in fastboot unless you are completely 100% stock. Once you do, the phone will verify boot chain integrity using RSA keys -- and you'll have a brick if anything has been modified.

*IF* you manage to get into TWRP, then your first business is to plug into the computer and back up anything important from internal storage.

Next (if you manage to get into TWRP) is to flash laf to make sure your Download Mode is intact. It sounded like you were on Oreo, in which case I would flash @weakNPCdotCom's StockLaf.zip from post #1 in the H932 20s thread. If you were on Pie, you should flash StockLaf.zip from post #1 of this thread.

Next you could restore a nandroid (TWRP backup) just system and boot partitions (not data) and hope that you can still get to your app data. But ideally I would do a TWRP factory wipe then a clean flash of stock ROM, either from this thread (if on Pie) or from the Oreo thread (linked above).

*IF* you manage to resuscitate your phone, I highly recommend to clean it up with a full LGUP flash of 10d: First Partition DL to straighten out the partition table, then Refurb. You can then update to Oreo or Pie either using LGUP KDZ or by using LG Bridge -- which always worked well for me on H932, although I realize it doesn't work for all models. LG Bridge also has a repair mode which re-installs the KDZ (and maybe does other cleanup).

As an aside, make sure you are using the latest LG USB drivers. And (as Chazz would point out) make sure to fully uninstall previous LGUP versions before installing another. Also, I know it sounds trivial, but Restart Windows to flush out gremlins. Shutdown does NOT actually reboot Windows, it merely hibernates and resumes the machine state.

I no longer have my H932, and when I did, I deliberately kept it on Oreo. My wife has an H932 and upgraded to Pie through OTA.

Good luck. Please keep us posted on your progress

Edit: Sorry, first version of this post was a mess, so please read it here and disregard the version in your email notification.

Hi, I managed to get into fastboot, and is recognized on the PC. I don't know what to do from there. I tried installing TWRP through it, but it says " FAILED (remote: unknown command) "

You cannot use fastboot on H932 to flash TWRP. If you could, it would have been the easiest LG phone ever to root, since it also allows for super easy BL unlock. Instead it's the hardest to root, because fastboot is mostly useless and because it cannot be cross flashed.

As I wrote in my previous response, try fastboot reboot recovery. I believe H932 has that command, though I don't remember. The purpose of this would simply be to boot TWRP. If H932 doesn't have that command, you'll have to keep trying Button Dance; make sure phone is unplugged and powered off first; press and hold VolDown and Power for 8 secs to force power off.

If your TWRP was lost, then the above won't matter. But if you manage to get into TWRP, my last post has my suggestions.

Otherwise the only thing I can think of is to keep trying Download Mode with different USB cable, different USB port, different computer, re-installed USB drivers, re-installed LGUP, different LGUP versions... The fact that you are able to start flashing in LGUP indicates that Download Mode may be intact after all.

That's really all I can think of. A rooted H932 is a stool with three legs: TWRP, Download Mode, OS. Each can be used to recover in different ways. Even without root, Download Mode can be repaired through the OS. But if all three are lost or inaccessible, it's over

It doesn't seem like that command works.
When trying to enter TWRP through the button dance it says erasing and then reboots.
I guess that's the end for my little friend. I appreciate the help :good:

Sorry to hear that.

So TWRP is gone for sure. You managed to complete Master Reset through Button Dance, which is good. But you're still not able to boot the OS after that, right?

But didn't you say you were able to do a partial flash in LGUP? If so Download Mode must be there. That's why I suggested you try different cables, USB port, computer. These often make a difference -- always much to the surprise of the user.

Whether it's worth your time, only you can say. Good luck either way

Edit: Another thought: Are you using the same computer as when you first rooted? Is it an AMD or Intel? I understand some AMD models are known not to work with LGUP.

Edit 2: Something else to try if the above fails, inspired by the post linked below: Find an OTA file (.up) newer than your current ROM, copy it to a folder named SoftwareUpdate on an SD card, put SD card in phone, try Master Reset again (in order to load stock recovery). Long shot, but worth a try.

I have tried tried different computers and cables. My v35 is recognized so I know it's my v30 at fault.

I'd like to try the .up method, but where do I find these files? Do I change the extension of a kdz or zip rom? I can't find .up anywhere

Understood (about the cables and all).

.up files are the actual OTA update files, not KDZ or ROM files. Search the V30 forum for H932 OTA files and see what you can find. Or try googling "H932 OTA files". These files are used when you force an update through LGUP FOTA mode (done inside the OS). But OTA updates were traditionally installed through recovery (although as ZIP files). Reading the post I linked (by @david.542569) I just wondered if that mechanism might still work, at least far enough to restore Download Mode.

A total long shot, but it's all I can think of at this point. Anybody else?

Did a bad one..

I have a phone converted to us998 and have been running roms no problem, was having some service problems and am on TMO so I thought I would try flashing this.

Followed directions in post #5 up to formatting data rebooted to recovery and NADA, tried charging, buttons. She Dead.. I am running Linux at the moment and am assuming I'll need to set up a Virtualbox to make any headway. can anyone provide some info to get me started on potentially unbricking?

Going to order a pixel 3 in the meantime but can't live without that DAC in the car...

I did a quick lsusb and in fact have the good ol': 9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)

Now accepting criticism...

Ouch!

As you found, H932 firmware is completely incompatible with all the other V30 models, and vice versa. Different RSA keys. If you flash it on a BL locked phone, you have a brick; blown Qfuse or something. But maybe yours can be rescued, since you are BL unlocked (relaxed RSA checking for recovery, system and boot partitions), and since we have a firehose (for all models except H932). Let me find the thread for that and get back.

Don't be too hard on yourself: You know you made a mistake, we all make them from time to time

Finally forced to flash this, since Edxposed development is dead and no longer passes Safetynet. Thanks, Google.

In case anyone else is flashing up from Oreo these days and finds thmselves with a busted/non-existent boot screen and System UI crashes upon boot: try not flashing everything at once. The only required thing to flash along with the ROM is no-encrypt (and that only if not using TWRP 3.2.1-2 or encryption isn't needed).

In my case, Magisk was causing the issue. Flashing the other stuff, booting the first time, then immediately going straight back to recovery and flashing Magisk finally allowed the phone to boot properly with root.

Hope this helps somebody.

LG has no bandwidth so be prepared to spend half the day just downloading the 2 KDZ files.

Is the 10h correct? I see it says it's for the H933. I'm assuming that's part of the plan.

Is this the most resent method?

The link for TWRP is not the newest version available for this device from what I see in the pie thread. Can we fix that?

Can the us998 firmware be flashed, anyone know?

What about my TWRP backup from a us998 data partition?

Any answers and help appreciated.

Thanks

 

[callihn]

I have also downloaded the H93310h_00_OPEN_CA_OP_1124.kdz file from two other separate sources and although the MD5 hash matches on both of those downloads it does not match the hash given on the LG link provided. What's going on with that?

Not on a T-Mobile H932. You will hard brick your phone.

Just to clarify, when rooting the T-Mobile H932 the only reason you would use the H933 firmware is to flash ONE partition -- the LAF partition, so you can install TWRP and then root. The only reason it doesn't hard brick your phone is because your bootloader is unlocked prior to that and the trust chain is relaxed to allow that one exception. If you accidentally flash the entire stock firmware of any model other than T-Mobile H932 on a T-Mobile H932 you will brick your phone.

The T-mobile H932 is the hardest of the V30 variants to root. You would be following these directions:

[ROOT] H932 - lafploit 1.5 up to v20a​

Understood. Though the issue still remains, the file I mentioned has a different hash listed on that site than all the others and in fact after wasting 12 hours of my life downloading it from that LG site it did not match the hash they have listed there.

So any any working link that is usable for this purpose and actually has more bandwidth than than an ISDN would be greatly appreciated.

Why is there even a recovery.img in the stock laff zip?
Please explain.
Thank you.

 

[ChazzMatt]

That would probably be stock recovery. When you install TWRP recovery it overwrites the stock recovery.

Anyone know why I cannot use youtube after flashing this fullstock rom? I think it has something to do with webview because some other apps are not working either. They just load forever but never actually work its like they cannot access the internet. Youtube loading spins forever. Any ideas? I have tried vanced youtube and same issue.

EDIT: Fixed my issue. Noticed my camera was not working either. Flashed permissive fix in TWRP. Everything appears normal now including YouTube.
