Lg g3 d851 running Marshmallow 6.0 Error flashing lollipop :/

I am Using 6.0 but It's draining battery too fast and I would like to downgrade to lollipop But when i flash it using the LG FLASH TOOL 2014 using kdz file then on download mode it just blink the screen of download mode and tool says RETRY
I have setup everything like driver etc everything is good and setup
I think it some thing like that 6.0 blocking to downgrade, I can't understand why this happening
And I have installed LGUP too is says "Please connect the known device" :/
Help

Had the same problem. You need to download the required DLL for LGUP to find the phone. Just google: LGUP d851 DLL and look for LGUP_8974_DLL_Ver_0_5.MSI
Once you install the DLL LGUP will work and you will be able to flash lollipot

Thanks a lot Brother :good::good::good:
It worked for me

How do I rollback to 10J MM? I am on 20a rooted and twrped BL-unlocked ..

Thought I'd ask again after month or so.
I am on 20a , TWRPED, rooted , BL -unlocked.
How do I properly downgrade to 10j MM? It has the same 01 rollback version so it should be doable right?
Thanks

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.

Sim lock happens ???????

Can the H830 be rolled-back all the way to Marshmallow 6.01 10j ?

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?

Upgrade Moto G7 non-OTA

After failed to to update an unrooted and blocked bootloader Moto G7 by OTA (security update was dated on Januray, 1), found yesterday to update the phone by PC with the Lenovo MOTO Smart Assistant (LMSA). This software can be used for updating or reflashing.
Found a very nicde description of reflashing by Akipe at the Moto G5 section. :good:
By upgrading the phone, don´t forget to backup with the bulit-in function of LMSA.

I always use Lolinet, download latest correct image, and then fastboot "flash-all.bat" the unzipped image.
