I have the T mobile H901 Like just about everyone else. I got it with android 6.0 and I wanted to root it. Now i didn't really know what to do, so I tried following some guides on here. I got my bootloader unlocked, but TWRP would not install, and I kept getting some "unknown command" error. So I installed this via LGUP: https://forum.xda-developers.com/tmobile-lg-v10/general/root-android-6-0-h901-t3382819
That gave me twrp, but I could no longer boot into system. From there I tried installing stock 6.0 .zip files, Installing .kdz files through LGUP, but nothing was working.
So then I tried this thread: https://forum.xda-developers.com/tmobile-lg-v10/development/rom-v10h901v20estock-customized-t3360240
I installed the V10_H901_V20L_Update_P1.zip, then the V10_H901_V20J_Stock_Custom_2e_FULL-signed.zip both though TWRP 3.0, and followed the rest of the instructions until I got to: "Once in Fastboot type this command "fastboot oem unlock"" BUT my phone already WAS unlocked. So I (not really thinking) typed "fastboot oem lock" and then it said "erasing data" like it was supposed to. But after that, I can do longer get into my recovery, Boot to system, and If I don't enter fastboot OR download mode, It stays in a bootloop where it says: "boot verification fail!! - Cause : MISMATCH_SIG_LEN
Please if anyone could help I would be so happy.
EDIT: I should also mention that when I try and flash the stock 6.0 rom with LGUP (The "H90120e_00_0316") It gets to 9% and fails with the error: Error Code - 0x2000, TOT antirollback version is smaller than device version.
OK I fixed my phone by using LG Bridge firmware update while my phone was in download mode. The only problem is NOW I can't root. I hope someone can get a Nougat root working.

Working with some Korean friends on that now. No promises but early testing is progressing well. Hopefully it works for 20 & possibly 30
So today i decided to update magisk to its latest versio, it all whet well,i did within android. later on in the day i decided to reboot myphone, and to my surprise it got stuck o thelgv30 thinq scree, after decide 10m was enough i rebooted and the it was stuck in bootloop, so i decided to restore my nanddroid , after it was done i hit reboot to system, and now it will only noot to fastootmode,, its as if there is nothing flashed to boot or system. any help will greatly appreciated.
EDIT: VERY OLD POST; WE CAN NOW USE NEWER MAGISK
____________
By "latest" you mean Magisk beta? You can only use stable 16.0 Magisk. Stated in the bootloader unlock/TWRP/root instructions that beta Magisk will mess up your phone.
Download Magisk or SuperSu. Magisk 16 (Use stable Magisk -- which right now is 16.0! Magisk "beta" will mess up your phone.)

You may need to Master Reset (wipe everything), reflash TWRP, etc. Good luck.

Probably. First Master Reset to clear everything. SEE if that works. Post 101 of the Frankenstein thread.
If that doesn't work, then go into download mode manually, then open dev patched LGUP and reflash Oreo KDZ.
Then use ADB to reinstall TWRP, and go from there. Your bootloader will already be unlocked so you'll continue to get the "scary" bootloader unlock warning. But you'll otherwise be following the instruction of the bootloader unlock thread, except for the bootloader unlock part.

I've tried using LgUP to try and get me back onto an OS, but it will not boot into the OS, only into fastboot. Anything I can do?
If you were using Trebel TWRP you have to use normal TWRP and restore the backup GPT in order for a stock nandroid to work or a stock based clean flash...

Download kdz flashable zip then extract it. Flash the system.img and boot.img file via fastboot
This just happened to me today. It was either from the newest Magisk (v22) or from the newest YouTube Vanced. Those were the only things that changed recently on my phone. Rebooted today and it will only go to Fastboot mode and that's it.
Master Reset will get me into TWRP, but I think my USB port on the phone is damaged, it will charge but neither my Windows nor Linux PCs will recognize that it's plugged in. So it's like only USB charging works but not USB data. So I think I'm screwed, idk if it's fixable. Sad day.
Am also stack here qhile trying to unlock my bootloader using @bilong9 thread on my v300l .please help
This also happened to me while trying to update to Magisk 22. First I had an error with Magisk in a restart cycle, then when I tried to update manually from the APK I got stuck in a fastboot loop with no ADB access. I was able to boot to TWRP from fastboot on my PC, then re-flash the Pie image. My settings were all lost, but I did get my phone back at least. BEWARE of Magisk 22, or at least until it's fixed for the V30!
edit: I found that I COULD install Magisk 22.0.zip while following these instructions for restoring my phone:
LG V30/V30+/V30S Bootloader Unlock & Root Method (With Clear Instructions)
(WTF...!) LG V30/V30+/V30S Bootloader Unlock & Root Method (With Clear Instructions) WTF...! LG V30,V30+,V30S (MOST VARIANTS) BOOTLOADER UNLOCK, TWRP, ROOT INSTRUCTIONS HERE >>>CLICK HERE TO POST #193
forum.xda-developers.com
after a few extra prompts from the Magisk app, v22 now works.
I've had no issues using Magisk v22 with an LOS 17.1 (Android 10) based ROM. It could just be that there's a problem with it on either LG stock or Pie ROMs.
UPDATE
* Variant: US998 US Cellular/Carrier Unlocked
* ROM: Rooted Stock Pie (US99830b)
* Magisk: v21.4
So it seems the issue is not that it "soft bricks", but something about the new installation process of Magisk v22 goes wrong with the /boot partition, causing the phone to only be able to boot into Fastboot mode.
After getting my phone fully recovered and restored from the last failed attempt (and making a new TWRP backup), I attempted the v22 update again. First Magisk attempted to download and install the new v22 app, and then a popup notification said "additional setup is required for your device, press OK to reboot". So I hit okay, and that's when once again I got stuck in Fastboot with no other options.
If you have a TWRP/nandroid backup, you can easily fix this by performing the Master Reset process in order to boot into TWRP, and then just Restoring the /boot partition from your TWRP backup. This will get you back to Magisk v21.4 where you were before, which is where I'm currently at.
At this time, unless Magisk releases a TWRP-flashable .zip for v22, or unless there's a way to update to v22 via Fastboot, it doesn't look like updating to v22 will be possible, at least for the Stock Pie ROM.
I've seen on both reddit and XDA that several people are saying they updated to v22 without issue, but it's unclear if they were on Stock or Custom ROM. My guess would be that Custom ROMs are probably working fine and it's the Stock ROM that's having the issue.

I simply renamed the available .apk to .zip and it flashed in TWRP.

If by "recovery" you mean TWRP, yes.
If you have unlocked bootloader and TWRP, unless you are flashing a TWRP flashable zip, then you need to flash full H930DS KDZ using Refurbish mode. Yes, you will lose TWRP recovery, but you can add it back with fastboot.
All H930 variants firmware (including H930DS) has fastboot. What have you flashed that doesn't have fastboot? Korean firmware does not. They have to flash to H930 variant firmware for bootloader unlock and TWRP installation, then flash to TWRP flashable zip to get radios back.

Thank you for your reply ChazzMatt,
But the problem and that my device is stuck on the LG Logo.
And if I press the power + Volume Down button, the screen turns black and then restart right behind.
So do you think I can flash the ROM KDZ with LGUP?

If you've lost download mode and fastboot mode then you'll need to do the button dance to get into QLD 9008 mode--then pay for a remote JTAG Octoplus box repair fix for $15-$35 (some give $20 discount to XDA members) on Ebay

We are in the same boat my friend. I have a V30 ( V300L ) LG+ korean operator. I have tried to update to pie several times without success. I have used a kdz from
lg-firmwares.com so I think I have used the correct software. LG bridge says it can't read the information of the cellphone. Also I have never received an OTA.
I have used LGUP for developers to upgrade it. Once the process is completed the phone gets stuck at the LG logo. I can fix this by downgrading to OREO using the refurbish mode of LGUP. It seems that my cellphone is gonna stay on OREO for long time. At least it hasnt bricked yet.

Detailed in the instructions for US998 Pie, as that has the most problems.
Hi guys, dealing with a H933 --> US998.
TL;DR - stuck on LG logo, no download mode, no fastboot, master reset does not work, LGUP (patched or unpatched) doesn't recognize phone, computer doesn't recognize it either.
----
Frankenstein method followed correctly, and had unlocked bootloader + root.
Followed H933 specific steps to install AOSP/Linage ROMS. Attempted to install Lineage 16.0 and flashed Lunar kernel. Booted to animation logo and didn't get past that.
Decided to revert back to stock Pie by flashing one of the US998 kdz's. To be honest with you, I tried a few different ones and everything was working fine (I went from Nougat --> Oreo --> Pie in order to bring myself back to Pie firmware to try Lineage install once more but with stock kernel).
This time, phone wouldn't move past the LG animation (right after the logo).
At this point, I lost access to download mode - but I still had fastboot. Installed TWRP again through fastboot and attempted to flash TWRP-JOAN_H933_CANADA_20i.
Lost unlocked bootloader image - lost access to fastboot and recovery - and still didn't have download mode (it would not pass the original download mode image) and would not be recognized by LGUP (patched or unpatched). The phone would be stuck at LG logo, and keep rebooting.
At that point I decided to try a Master Reset. On the second YES, it would hang, and then go back to the LG logo bootloop. Phone does not get recognized by computer.
I know I messed up in numerous points. I got overzealous and likely didn't pay enough attention. Spent all night trying to resurrect it, but to no avail. Any advice for me? Or is the device fully bricked? :crying:
Greatly appreciate any feedback and assistance. Thank you in advance.
Sorry to hear that. I think you have four options.
1) Reach out on the telegram v30 forum to someone with an Octoplus box to remotely resurrect your device.
2) Send it in for "repair".
3) Do it yourself, see https://forum.xda-developers.com/g4/general/guide-unbrick-via-external-sdcard-qfil-t3748946.
4) Buy a new phone.
The third option isn't hard, but may involve a lot of work so I'd go with the first one.
don"t worry too much, that phone is almost unbrickable, at least you are really unlucky, you will revive it. Wait for @ChazzMatt to give you some help before giving up hope entirely
Meanwhile, I can give you some advice because I was stuck one time on LG Logo, you were on which firmware when it last booted up?
While it is bootlooping, connect it to the pc, do a soft reset with power and volume down buttons, release them when the screen goes black and immediately press the volume up button to access fastboot menu, and if PC doesnt recognize it, shut down the phone by selecting it with volume button.
Deconnecting the phone and press volume down while reconnecting it to the pc to try to go to download mode and kdz your phone.
Somewhat working
Hey guys - brief update. I got back to US998 Oreo with bootloader unlocked and root. I tried to upgrade to US998 Pie by flashing US99830b.zip in TWRP following all the steps, and now the phone doesn't boot again and gets stuck on the LG Logo. Download mode shows "Now waiting For Any Connection" and doesn't detect PC. Any idea how to get this to work so I can flash back to US998 Oreo and just stick there?
Update: Flashed US99820H and back in running order. I still wonder how to get my phone onto Pie while keeping bootloader unlocked and have root, without having the phone get stuck.

Thoroughly discussed in the US998 Pie KDZ thread. Top of post #2 (one method), all of post #6 (three different workarounds).
If none of the 4 methods work for you, there are no other answers and you have to wait for another US998 Pie KDZ.
I've struggle for a couple days and finally i can flash pie stock rom to my us998. What i did :
1.Refurbish us99820h lgup, boot os
2.flash and boot twrp via fastboot
3.flash magisk,dm verity, rctd, via twrp...format data reboot format data then magisk again
4. Boot OS
5. Boot recovery then shutdown
6. Partition DL h93310h lgup except RECOVERY AND RECOVERYBAK
7. Boot OS .... Once your lg logo appeared ( BEFORE LG ANIMATION ) press and hold vol down + power. Release power and hold it again IMMEDIATELY once you see LG LOGO ( BEFORE LG ANIMATION ) click the "yes" and "yes"
8. You got the twrp
9. Flash us99820e + magisk via twrp , boot up
10. Refurbish us99820h, boot up
11. Do step 2 and 3
12. Boot OS
13. Boot recovery
14. Flash us99830b via twrp then flash magisk
15. Done u should have pie now
What you are describing is Method #3 in post #6 of the US998 KDZ Pie thread.
It's the workaround which has the most success but is also most complicated.

Yes.
What you are talking about is you can't run LOS-16 ROMs on stock Pie. You have to downgrade back to Oreo, and even then you will forever have to run permissive kernel with Oreo firmware for camera/flashlight to work since you once flashed stock Pie.
You would downgrade to Oreo 20h, flash all those steps (H933 Nougat, etc) and eventually get back to US998 20h and then stay there.

1) On my backup V30+ which is on stock US998 30b Pie (but doesn't have a SIM card inserted nor even signed into my Google account), it's connected fine to my home Wi-Fi network so I know it's not a stock US998 Pie issue...
2) This happens even on public free Wi-Fi networks? (Here in the U.S. we have McDonalds, Starbucks?) That would give you clue whether it's one particular router or all your phone has problem with. Or possibly problem with the type of encryption you have on your router.
Usually that message means the router is rejecting the device. You just have to figure out why. But is it one router or all?
3) If one particular router, try rebooting the Wi-Fi router itself.
4) Make sure you don't have any kind of router whitelist for certain devices or MAC addresses and your phone is not included. Or that you don't have some older b/g Wi-Fi chipset standard set; this one is not likely but I had that happen for an older Wi-Fi printer when I had "N" or higher set on my router.
5) On the phone, try forgetting the Wi-Fi network and refinding it. Enter in the password again.
6) Almost last, on the phone try the Network Settings Reset. (See screenshot from US998 30b Pie.) It will reset all network settings including Wi-Fi, Bluetooth.
7) Last, try Factory Reset?

How did you unbrick your phone? I'm in the same boat as you. I can get to the Download mode, but not past the blue dot image. If I try to master reset, the phone just restarts after the second time I select yes. It's been bootlooping like this for a while now. For context, I was on US99820H(dirty flashed via twrp) when I tried to flash H93330k. @ChazzMatt, I know this is a long shot as what I did was incredibly stupid, but is there anyway I can get out of this?

I tried to upgrade to US998 Pie by flashing US99830b.zip in TWRP following all the steps, and now the phone doesn't boot again and gets stuck on the LG Logo. Download mode shows "Now waiting For Any Connection" and doesn't detect PC. Any idea how to get this to work so I can flash back to US998 Oreo and just stick there?

Previous process:
Started from unlocked H931 Nougat
I'm afraid I actually forgot the precise order... maybe Nougat US998 -> Oreo, maybe Oreo H931 -> US998... Of course using Frankenstein method.
Using WTF..! method unlocked bootloader (I'm pretty sure at some point I also had twrp, and again, may have been prior to US998/Oreo flash... order).
Because of network problems flashed H931 Oreo, 2 years stable.
Current problem:
Flashed US998 Oreo from here: https://forum.xda-developers.com/lg-v30/development/us998-lg-v30-us998-us99820a040330-kdz-t3786337
Tried flashing US998 PIE from here: https://forum.xda-developers.com/lg-v30/development/us998-lg-v30-us998-us99830a000704-kdz-t3952256
In LGUP instead of refurbish I clicked partition dl.
Phone was stuck in bootloop. I tried the button dance to Master reset, worked, however the erased system wasn't able to boot before anyway, how would this help I don't know. The bootloop stays.
Hoped to reach familiar Download mode, but couldn't even power the phone off (in no way from across the forum). Opened the phone, disconnected the battery - it's off. Tried to enter download mode... doesn't work. At least it charges. Tried to boot, entered bootloop again, master reset, bootloop again, disconnect battery.
Found this: https://forum.xda-developers.com/lg-v30/help/download-mode-doesnt-anymore-t3973801 , which leads to a possible solution here: https://forum.xda-developers.com/lg-v30/development/rom-fw-lg-v30-joan-us998-30b-twrp-t3973811
I searched the comments, apparent solution was entering master reset menu and clicking yes in the dialog menus, which should start TWRP. I guess I don't have TWRP, because this does nothing much. A screen saying erasing appears, then goes to the same bootloop.
Bootloop, Download mode doesn't work, cannot acces TWRP. (soft brick)
Found no previous solution to work. (possibly couldn't find it)
Is there any help for me? Should I start looking for something less LG?
have you fixed it? Have you unlocked your device's bootloader yet?
If you have unlocked the bootloader then flash the laf.img file

If you want to update android 9 us998, please kdz via ROM h93030b to install twrp, then flash us99830b.zip via twrp
give it a try
Unfortunately not yet. Thanks for the tip, but until I find a way to boot anything on the phone, I guess I won't get to flashing.
I think @thao12345 is saying that (1) if your bootloader is unlocked (it must have been if you ever installed TWRP, unless you relocked it) and (2) if you are currently on US998 ROM, then you should have working fastboot flash commands, and you can fix almost anything.
Boot into fastboot from power off by holding Vol- while plugging in the cable. Of course ADB installed on computer. Test with "fastboot devices".
From there you can use "fastboot flash recovery twrp.img" to get TWRP, or "fastboot flash laf laf.img' to fix download mode. I believe laf.img can be found in the TWRP-flashable US998 ROM thread.
Once you have working download mode, the next step is to temporarily flash US998 Nougat using Partition DL and the latest Pie compatible LGUP. This should help clean up the phone.

right. If the phone is in us998 or h930, you can flash the laf.img file.
If not in the two modes above but get bricked then you can try the ways to enter "EDL qualcom 9008" mode then rewrite the partition using a tool such as QFIL

Are you having "Now waiting for any connection ..." error in download mode
Thanks guys, I get it now. I'll have to re-learn adb and fastboot, that's no problem I hope. I haven't had time to do it yet, I'll update later.

I don't have download mode at all, I only have 2 different screens - bootloop (V30/unlocked bootloader logo) or charging screen. I cannot access download mode.

If you can go to twrp recovery, you can go to reinstall the partition
If brick is black then try qualcom 9008 mode to rewrite the partition (I used to succeed this way)

Could you tell us a bit more about what you did? Which model V30 do you have? How did you lose download mode? And what steps did you take to repair it?
I'll be honest, I ask because having seen your many posts in various threads here recently, all very similar to the one you posted here -- sharing no real information -- I think you're most likely a bot, trying to build post count before dropping a spam payload.
That is presumptuous on my part and I may be wrong. If so I apologize deeply and will update this post after seeing your response.
