Is downgrading from ZVE to ZV8 safe? - Sprint LG G3

Is downgrading from ZVE to ZV8 safe? Last time I did an downgrade with the G4, it got hard bricked. I dont want it to happen again.

Took a leap of faith and did it.
For future reference, yes, it is safe to downgrade from zve to zv8.

What's a zv8?
And will it affect me being rooted?
Zv8 is a firmware version, but a few posts down someone asks if it will work on any firmware, he said yes. So as long as you are on a stock based firmware, you should be ok. Root doesn't matter.

Upgrading to lollipop from 4.4.2 with mdk loader

I am currently on 4.4.2 with a MDK bootloader. Originally I wanted to upgrade to Lollipop to use Magisk, but was informed that MDK is a fully unlocked bootloader so it wouldn't work.
That being said I would still like to upgrade to Lollipop. Without using the OTA method what is my best option? I have seen a few threads talking about different options, but most of them either don't mention MDK loader.
That being said maybe at this point in the phones life I just do the OTA update and loose the good bootloader. While having root is nice, I could probably live without it.

root h960a international model

Hi i have a question. I have lg v 10 h960a 32gb under marshmaallow can i root it with tot lolipop version systemrooted without unloking bootloader ? If there is really chance or it is a risk to brick my phone. Thnxs you
Hi,
if you flash the rooted lolipop tot you have a rooted phone with lolipop (of course), but not marshmallow. For rooting marshmallow you need an unlocked bootloader.
If there is a risk in flashing the lolipop tot in regards of bricking your phone I don't know. I always went forward in terms of android versions, never backwards, but I would expect that there are no issues if the tot file contains a complete rom and not just required changes to get a rooted lolipop rom.

Downgrade H830 to 20a

I've seen people say that they have successfully downgraded from 20i to 20a. When I tried it using the instructions at https://forum.xda-developers.com/tm...ock-h830-20a-rom-flashable-zips-imgs-t3511294 I just got an error, but LGUP wouldn't even tell me what the error was. Are there any instructions anywhere for downgrading as opposed to upgrading?
I try without success too! Someone can help us?

Should I avoid updating before bootloader unlock/root?

Very happy with my new V30 (H930), and looking forward to rooting it. I don't want to unlock the bootloader until I've had it a few weeks, so was wondering: is there any risk from upgrading the stock OS, that it will become harder to root and to install custom ROMs in the future, or to do any other kind of mod? (I know bootloader unlock will still be possible through the LG website.) Specifically, I now have 10f-222-01, and am now being offered 10g, and I expect it will then ask me to upgrade all the way to Oreo (don't know the version code for that).
Couldn't find any definitive info on this, but I have heard of advice for other phones that upgrading will make things harder or impossible due to encryption/partition changes, and vulnerability fixes etc. so I'm asking just in case.
Thanks

Yes. For H930, don't upgrade past Oreo 20D or 20R, until you unlock your bootloader. Right now you can manually flash the version you want with full image KDZ, which is superior to partial image OTA anytime.

While the official website lets you unlock bootloader no matter the version -- IF you have one of the approved models -- you have to waive your warranty. I did that with one of my open market LG US998 V30.
With the WTF bootloader unlock exploit you are not agreeing to waive the warranty. The WTF bootloader unlock exploit is also much easier and faster than the official method. It works on Oreo but starting with firmware which has July 2018 security update, the exploit is patched.
Simple answer is to not yet go beyond H930 20R. You can downgrade back to previous firmware (unless LG also blocks that), but why risk that BEFORE bootloader unlock and root?
After bootloader unlock, you can then update to latest firmware and still keep unlocked bootloader.
And we've talked about this SEVERAL times in Frankenstein thread, the WTF bootloader unlock thread, and I posted it at the top of the H939 Oreo KDZ and US998 Oreo KDZ and H939DS Oreo KDZ threads...

If you want to maintain the ability to root then avoid downloading any newer firmware versions than 20B(March 1st Security Update). You can use the LGUP software to flash kdz files containing the updates for your phone. It's best you update manually from Nougat to Oreo with kdz files rather than risk downloading the newest update that will likely fix the bootloader exploit. If you want to root your phone then you might as well go ahead; backup your data and do it.

Thank you, that's just what I needed. Sorry about repeating the topic - I didn't see those threads, and wasn't aware of the WTF exploit.
