Do not downgrade from ZVC - Sprint LG G5 Guides, News, & Discussion

Pretty self explanitory. There is no Zvc firmware released if u try to downgrade from zvc to lower brick will occur no fix available as ther is no Zvc firmware to reflash to fix.
This serves as a warning now.
If bricks occur its your own fault for not reading before hand.
As of rite now only fix would be to send to LG and pay to fix as they will know what has happend.....

ZVC is KitKat.. You sure you're not upgrading from zv8 to zva? (JB)ZV7>(JB)ZV8>(JB)ZVA>(KK)ZVC>(KK)ZVD>(KK)ZVE>(LP)ZVG
Just hit update again and again after each update until you get where you want. I'm sure you are now on ZVA or ZV8 if you're not on 4.4.2 yet and you did one update. You can skip all that by using a .tot file to ZVE. (Granted, you will lose any data you may have on the device)
If you want KitKat, go up to ZVE. If you want Lollipop, go up to ZVG.

when i bought the device it started update automatically from Jelly Bean to KitKat but was unsuccessful,, i tried 3 times but failed.... So can u tell me that can i update from Jelly Bean to Lollipop using .tot file and is there any risk of Sim-Lock after update???? another question is that does it matter that the device should be rooted or un-rooted before updating?

It should NOT be rooted for the update. You can't have any modified system files, or any stock system apps removed either. As of right now, there is no .tot for LP. You could .tot to ZVE and then update to ZVG(LP). I'm not sure since its factory unlocked if you'd lose the unlock. Anyone who has unlocked their device themselves has had the SIM lock back up after a .tot. So honestly, I don't have an answer for the SIM question.

do u know how can i make backup of current stock rom before flashing it?
I think that does not exist factory unlocked ls980. To upgrade you must be totally stock and if you are unlocked you arent. I advise you to wait some time until some dev can give you a good multi variant (and so unlocked) lollipop rom.

[Q] rooting/to Downgrade unrooted LP S4 i9505, needing Stock KK Rom !?

Hi guys, i am doing this for a friend, hes on offial 5.0.1 LP accidentally updated it and he doesnt like it.
we need to root it and then downgrade Bootloader and Modem then flash a Stock based ROM yes !?
i have fetched latest KK modem/BL from a thread on xda , one with WiFi fix supposedly.. and the latest KK BL as well.
but i cant find a Flashable Stock KitKat Rom anywhere.. can someone help me with this please !?
and maybe link me to the stock Modem/BL as well.. cause i dont wanna brick his phone.
for now i have only Rooted it with AutoRoot.
You don't need to root it in order to be able to downgrade. You might even trip Knox in the process, so you're on the safer side if you don't do that. But as you have probably already done that, you could back EFS up using EFS Professional or terminal, just in case it gets corrupted during flashing.
I'm not completely sure about the downgrade process and what it takes not to brick your I9505, but you can find stock KitKat firmwares (flashable in Odin) here and here. There are some stock KitKat firmwares here as well, but some of them are offline. You can find some firmwares at SamMobile too, but you will probably need to pay to download from there.
Some pre-Lollipop modems can be found here, some more modems and bootloaders here.

Helpp pleasee, firmware upgrade problem !

Hello guys,
I have updated my G900F to 5.0 lollipop and after i saw that Kit Kat is way better i wanted to switch back to Kit Kat. When i tried to get it back to Kit Kat via Odin, it got stuck! It said Firmware upgrade problem. I solved the problem with adding PIT file i found on XDA forums. But since then i can't update OTA and can't update via Kies Please help me solve this problem. I guess it's a problem with PIT file i installed but without it i couldn't solve the problem with Firmware upgrade. After updating i also got a problem with camera sometimes failing, it starts and shows black screen. It can be solved with restart but after sometime the bug comes up again. Please help me, this is really annyoing and bugging me a lot
Why do you want to OTA if you want to stay on KK?
OTA will take you back to Lollipop
If you are rooted / custom recovery, you can not OTA

I know but ever since update i have this camera problem, and i wanted to update over kies cause it's the safest way to fix the problem. Or do you think it's not a software problem ?

Help downgrading firmware LG V20 H91810K

I just bought a LG V20 H91810K and I was wondering how to downgrade the firmware so I can root it. I've read one of the post on downgrading it to h91810j but i'm new to this so i really don't know how to go about doing that. I've downloaded LGUP onto my PC. Can you guys point the way? Tutorial writeup or vids of some kind on how to downgrade? I'll try to figure out the rest once I've downgraded.
