Did you check it?
If not, can anyone else out there confirm you can downgrade to 20a from 20o using LG UP?

I can confirm it. Just flash the 20a over 20o normally with LG UP. Only hiccup I had was after the downgrade a lot of services kept crashing and the only fix was a factory reset.

Great, thanks for letting me know
I just downgrade to 20a successfully,according to the thread https://forum.xda-developers.com/tm...ock-h830-20a-rom-flashable-zips-imgs-t3511294
and i have a question: can 20o be rooted now?
whats the latest ota for H830? do we have a flashable zip?
I can't install the H830 20a KDZ. It's currently running 20o. LGUP tells me the that KDZ file is invalid.

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.

i hope yes
but locked bootloader state could avoid boot unsigned code ...

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.

F800K is the phone from Korean Telcom so you are going to have the same issue. I have the F800K this is how I know.

Wolf, could you please upload the LGUP you are using. All the ones I have found will not go past 9-10% when trying to flash the Tmobile .tot.
f800S?

Hi
Has anyone used this successfully on the F800K ?
Does it flash perfectly??
Could anyone post a new download link? Thanks!
I'm on Marshmallow OTA for my LG G3 D850. Does anyone know what the best way to root it is, and whether or not AutoRec works on 6.0? Need recovery to do a backup and did not want Marshmallow to begin with and was planning on installing TWRP and backing up before someone did the update so having trouble getting things ready.

thx

I am on 10A with root. Do I flash a 20C zip or will I brick it?
Do I have to update to each different version?
Thanks for any help.
Update via lg Bridge.
just connect your phone and pressing update button.
To answer the question, I flashed to 10D via Twrp, then to 20C.

Is 20c considered Nougat then? And are you going to update any further than 20c or just stay there? Thanks and sorry for the questions. Just confused.

Yes 20C is Android 7 and there are no roms past 20c as of yet. Just flash it via twrp and you'll be good to go.

Do I flash Autoprimes complete20c zip in TWRP. And the flash SuperSU separately? Or is there an individual 20c KDZ zip file I flash? Thanks for helping.

You can just flash the zip file then just flash super su immediately after.
Was wondering if the H830 with latest updates, be rolled-back all the way to 10j Marshmallow 6.01? or any version of marshmallow.
Thanks

You can flash any ROM ARB01, 10J - just like that, so you can!
How would you do this? I have a h830 with Oreo, and I can't install TWRP or flash anything at all.
I followed the instructions to roll back to 20a using LGUP, but have not had any success. When I attempt to flash TWRP, I get the message like "remote command unknown".
Don't know how to troubleshoot why the rollback is not working. Any advice or links?
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.
