I think it is very hard to root LG G8, especially T-mobile Version.

What about the unlocked version? Will that also be hard to root with OEM bootloader unlock?

Can this T-Mobile firmware be flashed over the Verizon software? Also, is there an unbranded firmware that can be used for American phones kind of like the way Samsung S series are?

Just got my tmo g8 yesterday, there is very little bloat. It seems to mostly respect lg's work. Not sure if that's a concern for you.

I thought the bootloaders were locked on all the US variants. How exactly would you flash this?

You can flash it with lg UP, but only to the intended variant, i don't believe we have a modified dll to allow us to cross flash kdz's between different models.

I wouldn't recommend it, but I used LGUP and installed the Verizon software on my Sprint phone by mistake. But to my surprise, the phone booted, and i could make phone calls.

Why you wouldn't recommend it? Not everything works? Or there are other issues?

1. I didn't check to see if everything else worked. 2. If you want to stay on Pie, and everything else won't work you will have to find someone like VLAD to install Pie back on your phone.
Pie isn't installed on Sprint yet.

Maybe I'm not putting it in the proper folder. Do you need root for this? What exact folder am I moving this to?

I tried with LGUP and it is still on V405UA, it won't swith over to V405QA. Am I doing something wrong, or since this was a Sprint phone it will only stay on UA not QA?
Thanks for any help anyone can give.:highfive:

Sprint V405UA to Korea Android 10 rom?

Hi,
Have heard of reports of people getting Android 10 via crossflashing to the Korean unlocked rom, but heard of possible caveats. Are there special steps to take? Besides loss of possible LTE USA bands in the firmware, anything dangerous about crossflashing to this
V409NO30b_00_OPEN_KR_OP_0515
firmware?
Thanks so much

Hello,
I have the same question. I'm tired of waiting Sprint for Android 10. Does it work with this Korean rom ? There is any step to be careful ? Thank you !
EDIT : if there is a Verizon Rom that work with Android 10, please let me know were to download it, i don't find it on lg-firmwares.com

Hello Phantafun/fireblade20, i have the sprint model. And i download the V405UA20A Verizon firmware from lg fan club and as soon as i booted the phone it requested me to update to Android 10, note i do not have a Verizon sim. I did not like the bloatware so i went for the Korean version V409NUA30d BEST DECISION EVER, nothing wrong, did not loose the network bands, plus the Korean version gets monthly updates.

Thanks a lot for the feedback ! I try it if as soon as I can get rid of the error 0x6004 CrossDl :/

sure ... because the korean version is 128 gb, memory, rom?

So, can anyone confirm that v405ua can be crossflashed with korean firmware?

I cannot flash the Korean rom (a new error code), but I finally get rid of the error code 0x6004 : i change the LGUP_Common.dll for another one found on another topic.
I'm on Verizon rom, it's really great : I can now desactivate the bloatware unlike the sprint Roms that lock this option.

I'm not clear on this. Is there a an android 10 ROM I can safely flash on a Sprint version?

I flash my Sprint V40 with the Verizon rom I found on LG Fan (lastest version I found, Android 9, and I received OTA update to Android 10).

DO you have any link to the instruction to cross flash it?
Were you root?

If you have an error code, you should try with other LG V40 DDL that you can find on Google or other topic on XDA.

Sprint Lg V40 LM-405UA to Tmobile android 10

Hey guys, I just bought an Unlocked Spring LG V40 lm-405ua that is on Android 9. Can I simply flash it to the latest Tmobile firmware which is Android 10? Thanks

No, you absolutely cannot and should not do that. T-mobile's roms / devices use their own specific hardware encryption / signature.
There's a caveat with virtually any of the major threads for pretty much all LG devices, and that is the guide / rom etc applies to ALL versions EXCEPT T-MOBILE.
And that's because of their own unique encryption / hdwr signature. Basically, you flash a t-mobile rom ONLY to a t-mobile phone.
cheers

meh, *delete*
