thanks !
working good on my G900EM !
here is the hidden menu code that worked for me : https://forum.xda-developers.com/t/lg-velvet-hidden-menu-code.4125641/
( #*462633*#900# )
PS : It didn t seem to work straight away ... I deleted previous fingerprints, rebooted and progressively entered only 2 fingers and it worked ... maybe it didn t like that I ve added 4 fingers the first time ...

Hey bro,
You don't need any DLL file.
To flash it you simply have to use same LGUP version used for LG G5 and follow same steps like you flash for KDZ files.
Just tried and it works perfectly
Also, LGUP can take dz file for upgrade (data stays intact).
is it possible to insert SuperSu directly into the restore file to have a pre rooted stock rom, while we wait for TWRP??

That's what @tungkick did.
He made prerooted .tot for G5 and .dz for G Pad X 8.0
Both are T-Mobile version with unlocked bootloader with missing fastboot commands.

Actually, locked bootloader does not matter anymore.
You have to do reverse engineering with hex editor to retrieve keys in order to bypass the bootloader. This is how Samsung Tab A6 can be rooted and TWRP installed even the bootloader is tight locked (and you have to patch the kernel to change SE Linux policy).

It would be great to bring all our computers together to crack the code like mining bit coins. How neat would that be.
Are you guys optimistic for root on the V20? Or will it be a similar story to that of the Note 7 with 99.9% stable root?
Thanks for your efforts.

T-Mobile LG G5 on stock Oreo (H83030c)

Is there a way to install a custom ROM on a LG G5 running stock Oreo? Can the stock firmware be downgraded to one of the stock nougat builds to help with bootloader unlock and TWRP install?

Yes, you can downgrade 30c to 20a, then unlock bootloader and install TWRP.
Is there a guide on how to do this? Thanks
I never found a solution to this and ended up getting a new phone. But that new phone just brokeand I am back to using the LG G5 again.
So now I am looking for a way to downgrade to 20a and the files needed to unlock the bootloader.
Appreciate any help provided.

Hi subaron what version are you on now? If you are on the latest 30C then you need to downgrade to 20A stock ROM first.
You must download the 20A kdz file and flash it with UPPERCUT. Then you enable Developer Options and can follow the info in this thread on how to install TWRP recovery and root. The only thing different from those directions is: instead of SuperSU, install Magisk.
Once you have rooted 20A with TWRP installed, then you copy the 30C COMPLETE .zip to the sdcard, reboot into recovery, and install that and install Magisk once again.

Common Questions:-
1) I cant Download OTA , What to do?
Ans:- Its normal, those who are rooted here cant updated directly,wait for Official release in lg website and my post or follow https://forum.xda-developers.com/lg-k10/how-to/guide-downloading-kdz-lg-bridge-t3504497!
***Do not magisk the same old-raw boot.img with updated firmware.***

https://imgur.com/GYk0nbw
3) How to Debloat some garbage like movies, sheets, slides, LG health etc ?
Ans:-Well! Its upto you what you like or dislike , but I'll recommend to uninstall drive (its upto u, my case no needs),duo,docs,sheets,slides,gmusic,gvideos---> and remove entire content ..260mb+ profit
For System App & Pre installed user app remover I recommend Multi tasking app called SD Maid Pro
After Installing go to overview --gain root access--go to settings--app control--tick include system app and --back to app control
Here u can find Some garbages like LG smart world(if u need wallpaper ,theme etc dont uninstall),lg health,Email,lgcloud,quickhelp,pocket adviser .
:good: Click the app , Scrool down to Delete/Uninstall,restart.
Enjoy Rooting :good:
@chirantantab Thanks for the guide , what i was thinking that , if we can use European pie ( 710em ) in our indian G7 emw. Right now the only problem is if we use euro pie , we ll lose volte. But i think if we are rooted and can change system files then we can enable volte ( as i did in my international LG g5 )
Benefit of this is that we dont have to wait for release of indian updates.
Let me know if you can try by flashing euro pie .
To figure out , how to enable volte in international rom , search for my thread in google with " Lg g5 volte fix "

You can unlock the bootloader only on A11, on A12 it is impossible. You need to go to A11, unlock bl and then go to A12.
