Phone stuck in fastboot LG V30 H932 - LG V30 Questions & Answers

I have a LG V30 H932 device that is stuck in fastboot mode. I can get into download mode to flash kdz but that is all. I tried countless times to flash kdz to fix like what the internet says but i have no luck. Please help. I recently flashed H93220K Oreo to it. It still is stuck.

Either there is a hardware problem with your phone, or you wiped out a partition that doesn't get flashed by a KDZ but is required to boot your phone.
Hardware problem would obviously have to be handled by LG, but if you can give some more info on what you were doing that caused this to happen, I can probably help you fix it.

I unlocked, relocked, unlocked, then relocked it then tried flashing the kdz hoping it would erase the bootloader unlock counter instead i have this problem.

You can't erase the bootloader unlock counter. Otherwise why would be of any use to the OEM/carrier to see if you have unlocked your bootloader?
EDIT: According to @runningnak3d, apparently you can erase it, but it's not easy and you needed to make preparations BEFORE unlocking the bootloader the first time.

Did you let it boot each time you unlocked / relocked?

Actually you can reset the counter, just not by flashing a KDZ. Unlike Samsung, the unlock counter isn't stored in an eFuse.

Interesting. I did not know that. In researching, I didn't find that answer. Thank you.
Then what use is it?

The only way (that *I* know of) is to make a full backup ... and I mean FULL -- every partition except userdata, when you first get the phone -- heck before it even boots. When you are ready to sell your phone, or if it needs a repair and it isn't so toast that you can't do a restore, then you restore that backup. If your phone is so broke that it won't boot, I have never had LG give me grief.

Ah, I re-read your answer! So, user can NOT do by simply re-flashing KDZ. User needs to make preparations well before unlocking the bootloader the first time.

Yes. I had to set it up and open the dev options to allow OEM unlocking.
Is there any hope for my situation or am I up s**t creek without a paddle with this phone (pardon my language)?

I called LG and explained my problem and I mentioned that the bootloader is unlocked and they told me that because the bootloader is unlocked I have voided the warranty.
Also...a little side note, the LG V30 is the first V flagships I have come accross that explicitly says in the bootloader menu that unlocking it will void warranty (therefore this is where the need for a bootloader unlock counter comes in).
If your carrier sees any numbers in the bootloader menu (any trips) then they won't help you because the warranty is voided.

The others that use the WTF exploit do not have to waive warranty to unlock their bootloader.
It still may be voided --but there's nothing stating that because we are doing it without LG permission.
On one of my US998 V30, I have LG's OFFICIAL bootloader unlock code. Had to jump through hoops proving I was original owner, the IMEI, the DEVICE_ID, etc -- and had to waive the warranty. Then I got the bootloader unlock code -- which only works with that one phone. After bootloader unlock, of course I had full fastboot flash commands.
T-mobile H932 doesn't have those fastboot flash commands. That's why we said the T-mobile H932 only has "fake" bootloader unlock. @runningnak3d worked around that with his laf exploit, but took some real work!
Whereas with WTF (which H932 cannot use), we don't need LG's permission so there's no AGREEMENT or NOTICE your warranty is being waived. I've used that on US998 V30+, which is NOT eligible for LG's official bootloader unlock code.

1) I was replying to your comment about voiding the warranty. You brought up the topic, not me.
2) You obviously did not actually read it, because I was not "lecturing"on anything. I was giving information which may help others.
3) I will reply to what I want and how I want.
4) Try a MASTER RESET .

UPDATE
I got the bootloader unlock cohnter to reset to zero using "fastboot flashing lock" or something and it reset the counter. T-mobile replaced the device under a warrenty replacement.

I have root on Lollipop, can I use it to unlock the bootloader?

I have a h960AY rooted via the tot method, so no bootloader unlocked.
The LG developer site doesn't give me an unlock option because my device is from a Telecom (Orange).
after attending an event for LG the VP operations for the RonLight said in front of 30 people that unlocking the bootloader will not damage warranty, so I feel fine doing it.
If I already have root, I should be able to write to any part of memory I want, no ?

Yes, having root access means one can write anywhere on the flash you want to. Alas, in order to unlock the bootloader you need to know where to write in the flash memory. Most likely somewhere in /dev/block/mmcblk0p25 (the "misc" area) is a bit that can be flipped to unlock the boot loader, but at this time we don't know which one and even this much is guessing.
At this point we either need LG to unlock the bootloader or else do some analysis/cracking of the bootloader to figure out how to unlock it. This is not simple, but if someone has the time/skills it should be possible. (or if an annoyed LG employee is up for releasing details anonymously)

Test for Fastboot Commands? (Tmo LG V30)

So I got the T-Mobile Variant of the LG V30 and ran command to unlock the bootloader and it seems to have unlocked it as well as wiping the data and cache. I know with previous LG devices with T-mobile that the there were no commands to be able to write to the device. Is there anyway to verify if this is the case?

This is very interesting, I wonder if bootloader is unlocked on the upcoming "sim unlocked" US998 as well? If the T-Mobile bootloader is unlocked this may be a game changer.
Apparently you can unlock bootloader but cannot run ANY other commands. So, its basically useless.

if only i would've seen this earlier because that's what i ended up trying out in adb and boom a voided warranty and i didn't get time to take up the daydream offer since i'm sure they will be able to see i already voided my warranty. . In the mean time i have pulled a couple of files out like for example system(i used the adb pull /system), vendor( adb pull /system/vendor) and frameworks(adb pull /system/framework). ive just been poking around trying to see if there is any way to find the boot image. any ideas where it could be located?
If you have pulled system. can you please check if you have any *.mbn files there. If yes then copy, zip and attach them here.
These are lte modem configuration files which interest me much.
Thank you

It has been discussed in the LG V30 Unlock bootloader and Root thread as well as the more specific T-mobile LG V30 root effort thread.
This post (October 7) shows commands a T-mobile LG V30 user tried after unlocking his bootloader:
https://forum.xda-developers.com/showpost.php?p=74080195&postcount=112
And here's other exchanges in that same thread:
bp328i said:
Try "fastboot oem device-id"
I bet it fails which means yes the bootloader can be unlocked but adb is disabled so no way to load TWRP or any custom recovery. This would be the same as on the T-Mobile G6.

ShadowDXS said:
It does fail. That means we will have to download the image for TWRP on the device, and if root is gained we can then cp the file to the recovery directory. That blows.

So there we have it. It's locked just like previous models. Now we wait for the unlocked variant...
Edit: locked as in the fastboot commands have been disabled the same was they were on the g6
Click to expand...
Click to collapse
With the fastboot commands disabled you need root to install TWRP or you need TWRP to get root, and neither is possible right now.
The posts above are from the more general LG V30 Unlock bootloader and Root -- general because it covers ALL LG V30 models, and it's pretty much agreed only the official carrier unlocked LG V30 US998 and H930 will have "real" bootloader unlock with full ADB fastboot commands. That doesn't exclue that some exploit might be found by devs, but just if you want easy bootloader unlock and root -- like with the LG G6 carrier unlocked models, which have root, recovery, ROMs, kernels.
_________
However, this is the thread below is to specifically discuss the T-mobile LG V30 root efforts:
T-mobile LG V30: Progress Towards Root/TWRP/ROMs (not achieved yet)
If there's any dev magic, that will be the thread to watch.
Initially the op did not specify he wished to only talk about the T-mobile LG V30 instead of all LG V30 models -- but once we got that clarified (the first few posts on page 1) then that's what the rest of the thread is about.

Been discussed in depth since early September in the bootloader unlock and root thread -- even before the LG V30 was released. Well known, the T-mobile LG V30 would have an "unlocked" bootloader -- but it doesn't do any good because the ADB fastboot commands are removed. (September 3)
The official carrier unlocked US998 and H930 models -- the ones NOT sold by any carriers, what LG calls for the "open market" will be placed on the LG Developer Bootloader Unlock list AFTER release, and will be eligible for bootloader unlock. They will have full ADB fastboot commands. Just like the LG G6 models then they will quickly get dev support for root, recovery, ROMs, kernels.
The official carrier unlocked LG G6 US997 was released May 12, 2017 but was not placed on the the Bootloader Unlock list until June 29. SIX WEEKS. However, there's now tons of dev work available.
Let's hope it doesn't take that long after the LG V30 US998 is released!
Whereas, the T-mobile LG G6 while ostensibly having an unlocked bootloader still has no root or recovery. Six or seven months later, still no dev work available.

T-Mobile H932 has crippled ADB.

That last thread was started back in early September -- and even then on the first page, we detailed the issue T-Mobile LG V30 would have, based on the T-Mobile LG G6.
Both the LG carrier unlocked versions have official bootloader unlock and root, while the T-Mobile model has a bootloader unlock but most of the ADB flash commands are removed. The T-Mobile LG G6 STILL doesn't have root.

yes as always for LG TMO's , but probably you still don't have write commands enabled on Fastboot.
You should only be able to send "read" commands from there

If i will try to unlock the H930G Israel model (no carrier) using this method (fastboot) - will i theoretically have write commands?

You can try on the LG Developer Bootloader Unlock list website, but when you put in your IMEI or serial number or whatever they go buy, they'll probably say the phone isn't eligible. Same way U.S.Cellular version is not eligible...
But wouldn't hurt to try. LG system could have a snafu and you might very lucky.
Goodbye warranty for no benefit. you have no fastboot commands, so it is useless to unlock on your phone model.
and the phone keeps track of if the bootloader has been unlocked, even if you re-lock it.
That might be a big deal for some but the way I go through phones I'm not too concerned.

Yup.. Didn't need unlock.bin.. Just like you said.. Strange.. Has anyone tried using write commands or is everything I'm reading assumptions? I can't find proof of What was tried anywhere.. What if twrp recovery worked? No one can confirm really unless it exists.. What if writing recovery is one of few commands that might work.. Any information would be appreciated..

What you did is useless. Been discussed for a hundred pages elsewhere. Notice you've dug up an old thread from December 2017?
Right now (September 2018), every V30/V30+/V30S on the planet can be bootloader unlocked and rooted ----except for T-Mobile H932. Been that way since mid-May 2018, when we discovered the WTF Oreo bootloader unlock expoit.
H932 does not have any fastboot flash commands, so cannot be rooted. Also, since it has different RSA encryption it cannot be converted (Frankenstein) to carrier unlocked US998 which does have fastboot flash commands, like all the other North American variants.
See post #2 of this thread you are in for more information. I notice you quoted post #1 but didn't quote post #2? There were only 7 posts in this thread before it died off! If you can't find proof it's because you haven't actually looked... Here's post #2, from December 1, 2017:

Go read THAT referenced thread, which is current, and is up to 148 pages now. H932 may get root eventually, but right now still impossible.
Also, you could have bought a carrier unlocked V30 and use it on T-Mobile and have root. Or you could buy a mint LS998 for just over $300 off eBay, convert it to carrier unlocked US998 and have root.

What's wrong with it?
Your V30 is obviously a used phone and previous owner had unlocked the bootloader.
The bootloader was locked back before selling or else you would see bootloader unlocked warning every time you reboot. Like I see on my phone.
If you think/know your phone is brand new, then there's an issue where someone unlocked the bootloader at one point prior to sale, but locked it back.
Requesting this be moved to Q&A. It's in wrong section.
Is it possible to make it official again? If not, I If it's not possible, I'il give it back. Thank you.

It's got stock firmware and the bootloader is locked back. It is official.
If you mean counter set back to zero, I don't know. That doesn't affect functionality whatsoever.
Your phone was not new, right? Used by someone else before this, right?
Yes it is. I bought a friend's device. Where can we see counter 1 or 0 Thank you so much.

Question TracFone unlocking policy

Do they mean network unlocking or bootloader unlock? Has anyone been successful in unlocking their bootloader on this website?
I have this device and it's for cricket and it says not a supported device at the Motorola website. So tho I have the twrp I can't flash it until I unlock my bootloader which I pray someone can get around. That's what you guys do fingers crossed....but until there's a way to unlock my bootloader I have to look at the twrp and root images without being able to use them or root ....someone told me you can flash a different bootloader so I figured someone with the same Motorola G Power 2021 but different carrier can provide you their firmware and images for boot and so on. Plz help thanks again and Merry Xmas to all

You could always download the firmware from other moto builds and variants on the lolinet site. The problem is you will most likely brick your device attempting to flash, if you're even able to, or using RSA to trick it into recovering a build not designed for your phone. I'm not experienced with Cricket devices, but I'm assuming since they are based on ATT network that they are not eligible for bootloader unlocking. Though that's a huge guess on my part since that normally is up to the carrier and both ATT and Verizon find much of their purpose executing their right to do so to their hearts content.

That website talks about "network unlocking" as you call it. Not bootloader unlocking.
