Hi,
How to root LG SU 640 with V20F firmware. My phone was on V20D rooted, then updated to V20F with LG PC software and lost root. Procedures for older versions seem to be not working with this. Is there any way to root? Need root to 1. uninstall annoying Korean SKT apps, 2. install custom ROM.
Thank you.

Revert to GB rom, root, flash custom recovery, flash custom rom.

Thanks, If I want to stick with stock for a while then? And flashing ROM is a tedious process, I would keep it as last option. Noway to root V20F?
you can root it, you cant put custom recovery.
best bet is to get back to GB root, custom recovery, put custom Stock ics rom if thats what you want.
Edit: i have rooted it but dont remember if that was 20D or 20F, but i did get root and able to delete system files. but get soft brick every time i tried to flash recovery. but after the new wind kernels i forgot about ICS and stock ROM's.
I flashed a 20b ROM but now want to go back to kitkat so I can use my unlimited wifi tethering.
The ROM thread says to flash the 10r bootstrap before restoring to my saved kitkat nandroid, but when I do and then reboot it, I have no Data.
Im pretty sure I am still using the 20b modem. What do I need to flash to restore back to kitkat?

If you didn't backup your efs then you're stuck on lollipop ?
Any update or changes to this? I use an app at work that does not work on Lollipop at all.
I NEED Kitkat...
Give this method a try...

Other than having your phone replaced, this is the only method I know of that actually works for restoring LTE after a downgrade. Here's a link to the original thread...

I am coming from a G2 where we had to flash a baseband then flash CloudyG2. I now have a G3 in hand that is stock and on 4.4.2 and the model is D851. I only have to root, install custom recovery, and flash CLoudyG3 2.2 and no other baseband/modem/zips? Is that correct?

CloudyG3 2.2 is Lollipop i think
So i would think that you would need to flash the lollipop baseband if you are currently on KitKat

Thats what I thought too, but there are vague references in the the main thread that say it contains the bootloader in the zip file for the rom.... I just wanted to make sure so I thought I would ask here.
I decided to live dangerously and just give it a go after backing up my current rom. Works just fine. No need to flash a baseband first as I believe the zip file includes it.
Hello.
I kinda would like to try the LG G3s Lollipop firmware but I have a question, if I upgraded to lollipop and then root and installed TWRP would I be able to return to KitKat using my 4.4.2 nandroid backup (In case I didn't like it or battery was poor) or would the baseband have a conflict and not work. Also I am currently rooted now on KitKat with TWRP installed, if I were going to update how would I do it without bricking? Do I have to unroot and uninstall xposed?
Anyone?

You can downgrade to KitKat with Nandroid

Okay, and this wouldn't cause a baseband conflict with stock 4.4? Or cause modems to not work anymore?

It depends on the backup you have.
You can definitely downgrade the G3 using kdz or tot files, but they contain the baseband and modems within themselfs.

The backup I have contains: Boot, Cache, Data, EFS, and System partitions... A full Nandroid backup... I have almost all the KDZ files for the US990 but need the 10c firmware for it as that is what I am on, I have been unable to find the 10c firmware and that's why I want to know if a full Nandroid backup can get me from stock lollipop back to 10c kitkat

If I'm not mistaken the EFS partition contained the modem but not the bootloader.
Custom ROM zips shouldn't affect the EFS and bootloader anyway, but you should have a backup of the EFS just in case.
And you'll always be able to downgrade using a flash tool and KDZ or TOT files.
Also I recommend trying a 7.1.1 AOSP ROM, performance is much better than stock plus you'll get the latest security updates.

Unfortunately the US990 only has two ROMs and getting 7.1.1 is very unlikely as nobody really owns that device anymore....

Here's my experience, I'm currently on a stock version of 4.4.2 Kitkat with TWRP 3.0. I went up to MM when it first came out, not enough of what I needed was compatible at the time (mostly xposed stuff) so I reverted to my 4.4.2 nandroid backup. Everything worked except the modem. I ended up finding one, installing and everything was the exact same. It's been a long time and I use 10R but i'm assuming the process is the same.
You don't have to uninstall TWRP, just backup everything, wipe and install new rom. If you don't like it, revert to backup. Make sure you don't delete the backup and make sure you have the latest TWRP.

That sucks. If one of them is AOSP based, I've always been getting better performance on good clean AOSP ROMs compared to stock.
My d851 is currently rooted and running Lineage 14. It originally was running 30d, which I rooted with kingroot, installed twrp with flashify, and then finally installed Lineage through the twrp recovery.
My question is, does it make sense to upgrade the modem of my d851 with the modem from 30E from here? If so, how would I go about doing that while keeping Lineage? Just flash the modem file in twrp? Or would I need to flash the bootloader as well?
