Probably a stupid question... but. - LG V30 Questions & Answers

I bought a LG V30+ (V300) Korean version and I was wondering if it would be possible to flash an international stock rom on it.
Is this possible?
Anybody experience doing so?
Thank you.

There is no chance to fladh anotoher Rom in ours Lg V300k yet. First will be needed to unlock our bootloader (not achieved yet), then TWRP and finally to have suitable ROM's for ours devices.
Step be step, lets be patient

On LG V20 they flashed another ROM (KDZ) using a custom made LGUP.exe file -- BEFORE the bootloader was unlocked. They did it in order to unlock the bootloader, installed TWRP, then flashed back the orginal ROM while keeping TWRP.
https://forum.xda-developers.com/showpost.php?p=74689131&postcount=123
However that method would only help you (on South Korean variant) if you then had a way to unlock the bootloader AFTER you flashed it.
This "flashing another KDZ variant"method would possibly work on the T-mobile H932 which already has easily unlocked bootloader, but just has most of the ADB flash commands removed. It would temporarily turn the H932 into an LG US998U once that KDZ is available. Install TWRP, flash back to original H932 firmware, while not overwriting the new TWRP recovery.
But doing that on South Korea model won't let you unlock bootloader because your IMEI is ineligible on the LG Developer website, and the bootloader unlock exploit the V20 devs used has been patched.

Shouldn't that be possible on this? Or was there a patched exploit after that? Sounds similar to the G4 if I remember correctly.

The bootloader unlock exploit they used on the V20 has been patched, but the T-mobile H932 V30 doesn't need a bootloader unlock exploit -- bootloader is easily unlocked. What it needs is a US998U KDZ and a custom made LGUP.exe to allow installing KDZ from another variant. That custom LGUP.exe is what does the magic, but a dev needs to make one that works on the LG V30. Go follow the links I posted.

sprint lg v30 can i flash other carrier roms

When i had my galaxy s7 on sprint i was able to flash other carrier roms and unlocked version roms through samsung flash tool .Can this be done with lg phones on some kind of flash tool ? Sorry for question just was wondering i use to flash unlocked version on my sprint v30 to have a bloat free phone
So the question I have is this. If you are going to root and unlock the phone anyway, why not just remove the bloatware on the phone? Why concern yourself with other carriers?
If all the carriers are equal as far as communication frequencies are concerned, then unlocking the phone is all you really need. Once unlocked (you don't even need to root for this) you can go to any carrier.
I could do that without root. And flashing unlocked version rom has no carrier bloat. Also i said nothing about rooting

If memory serves and may not, so unless something has changed, flashing any function on an android phone requires root access.

"Unlock" has different meanings in a dev forum. You mean carrier unlocked, SIM card unlocked. Not bootloader unlock.
U.S. Cellular has SIM card unlocked, carrier unlocked version. The "open market" version which will be released in early December will be both carrier unlocked and will be eligible for official bootloader unlock.
You basically want to convert your phone to another phone? Yes, with Samsung phones you can do something like that with Odin. I have a friend who bought UK Galaxy S8 and flashed Australian ROM (with Samsung Pay) through Odin. He's not rooted and doesn't want root.
There is an LG flash tool, to flash KDZ and TOT firmware:
http://www.droidviews.com/download-lg-flash-tool-to-flash-kdz-and-tot-firmwares/
I know with the V20 H910, once Dirty Santa was patched in order for someone to root their phone, they had to basically flash their phone to an older Freedom ROM, which was not yet patched, then install some engineering mode module, and then run Dirty Santa.
https://forum.xda-developers.com/showthread.php?t=3664500
So, some of what you're are asking can be done. But that ROM flashing was temporary and on some carriers you would lose signal. It was just a step to getting the bootloader unlocked and TWRP installed. Then the regular H910 ROM was reinstalled, and all signal functionally restored.
____
NOTE: this is a very simplified answer to the question. There are even "patched" versions of the tools to allow you to flash versions you aren't supposed to.

No, after the V20 LG has now added signature checks so you can't flash other variants to convert to another.
This was not widely known a few months ago. We thought that V20 trick would still work.
Too bad.

LGM-V300L on H930?

Can I play SW with the Korean version of V300L on the European version of the H930 using LGUP and KDZ?
Do you need to unlock the bootloader?
Thank you...
EDIT: no.
___________
possibly, if you have a custom version of the LGUP.exe.
On the LG V20, they did it BEFORE unlocking the bootloader so they could flash a KDZ for another LG V20 variant that allowed unlocking the bootloader with Dirty Santa. YES, I know Dirty Santa has been patched and does not apply to this phone. My point is they flashed a KDZ for ANOTHER LG V20 variant, using custom LGUP.exe-- BEFORE the bootloader was unlocked.

Should I avoid updating before bootloader unlock/root?

Very happy with my new V30 (H930), and looking forward to rooting it. I don't want to unlock the bootloader until I've had it a few weeks, so was wondering: is there any risk from upgrading the stock OS, that it will become harder to root and to install custom ROMs in the future, or to do any other kind of mod? (I know bootloader unlock will still be possible through the LG website.) Specifically, I now have 10f-222-01, and am now being offered 10g, and I expect it will then ask me to upgrade all the way to Oreo (don't know the version code for that).
Couldn't find any definitive info on this, but I have heard of advice for other phones that upgrading will make things harder or impossible due to encryption/partition changes, and vulnerability fixes etc. so I'm asking just in case.
Thanks

Yes. For H930, don't upgrade past Oreo 20D or 20R, until you unlock your bootloader. Right now you can manually flash the version you want with full image KDZ, which is superior to partial image OTA anytime.
https://forum.xda-developers.com/lg-v30/development/h930-lg-v30-european-market-h930-t3779076
While the official website lets you unlock bootloader no matter the version -- IF you have one of the approved models -- you have to waive your warranty. I did that with one of my open market LG US998 V30.
With the WTF bootloader unlock exploit you are not agreeing to waive the warranty. The WTF bootloader unlock exploit is also much easier and faster than the official method. It works on Oreo but starting with firmware which has July 2018 security update, the exploit is patched.
Simple answer is to not yet go beyond H930 20R. You can downgrade back to previous firmware (unless LG also blocks that), but why risk that BEFORE bootloader unlock and root?
After bootloader unlock, you can then update to latest firmware and still keep unlocked bootloader.
And we've talked about this SEVERAL times in Frankenstein thread, the WTF bootloader unlock thread, and I posted it at the top of the H939 Oreo KDZ and US998 Oreo KDZ and H939DS Oreo KDZ threads...

If you want to maintain the ability to root then avoid downloading any newer firmware versions than 20B(March 1st Security Update). You can use the LGUP software to flash kdz files containing the updates for your phone. It's best you update manually from Nougat to Oreo with kdz files rather than risk downloading the newest update that will likely fix the bootloader exploit. If you want to root your phone then you might as well go ahead; backup your data and do it.

Convert the H931 to US998. You will have truly carrier unlocked V30. (You will also no longer have AT&T bloatware.)
See Frankenstein instructions.
This happened to someone else who bought "unlocked" AT&T H931 off eBay.

Well known issue. Read the Root Sticky, see post #2, point #2:
ROOT YOUR V30!
https://forum.xda-developers.com/lg-v30/how-to/root-v30-t3927154
It tells how both former H931/H933 need much extra prep work to run AOSP/Lineage custom ROMs, even when converted to US998.
If you look in the Guides section you'll be a thread of two which tell the additional steps for former H931/H933 to run AOSP/LINEAGE ROMs.

Also briefly mentioned in the WTF INSTRUCTIONS themselves.
See the Custom ROMs linked reference. It goes to the Root Sticky, linked above.
But since it's outside the scope of bootloader unlock, TWRP installation and root, it's not delved into deeply.
Many people like myself run rooted stock firmware with various mods (Anxious V30, Gravity Box, etc) instead of AOSP/LINEAGE ROMs.
