I'm currently on G2 apps rom V5, but wanted to try out KitKat and Sphinx rom,
I know there is the KDZ method of going back to stock, however I was wondering if I could load my backup from stock JB 4.1.2 before installing G2 apps V5, unroot, and then work from there. Is this method possible? Thanks!

I don't quite understand what you're asking, but I'll try my best to answer.
Are you asking about the stock OTA Kitkat when you say "Kitkat"?
If so, then if you restore that backup, then you'd also have to somehow restore the recovery or else the OTA will not work.
You will be back on stock 4.1.2 though and can flash any rom you want, so if you get one of the flashable versions of the stock Kitkats, then you can flash it without issue.
If you are on the E980, then the flashable Kitkat is here: http://forum.xda-developers.com/showthread.php?t=2760895
You shouldn't have to return to stock to flash Sphinx. All you'd need to do is format System, Cache, Dalvik, and Data, then flash.
Thanks for the reply sorry for not being more specific.
I have a 240L that was on 4.1.2 when I rooted and flashed the g2 apps rom.
I have been reading that I will brick the phone if I try to flash from my current rom, and that I need to OTA update from 4.1.2 to 4.4.2 as well. I didnt realize about the stock recovery though so the only way to get that back is thru flashing the KDZ file anyway?
Thanks again for the reply!

I'm currently trying to flash stock firmware via KDZ, however, the method provided on xda is not working for me.
LG Support tools is telling me that my software is updated already and is not letting me flash the KDZ.
What am I doing wrong? Please help, thank you...

I have the T999 SG3 model, am rooted and currently running the Wicked v10 rom. I want to try out the 4.3 upgrade and was wondering what the best/safest way is to do this. I already did a nan backup. Do I need to unroot? Thanks in advance for any help/suggestions.

If you are looking to have your phone download the OTA, then you'd probably need to wipe and install a stock rom. You would then lose root, however. Not sure what the implications of that would be, but I'm sure you'd have to use ODIN, etc, etc, to get back to rooted and custom rom.
I would just flash the stock ROM from DocHoliday's thread instead of going through Odin.. Don't have to worry about Knox or anything, and if you don't like it you can easily wipe and restore your nandroid

I am running IOKP 4.3.1 on my nexus. I have downloaded the OTA update for kitkat 4.4. Can I flash the 4.4 update from cwm or so I have to return to stock then flash it? I ask this because my stock backup will not restore due to md5 mismatch. Thanks for any advice.
Anyone?
Just backup, restore a flash the 4.4 ROM.

You can only flash an OTA if you are on stock ROM.
OK but how do I get back to stock ROM then? My backup won't restore.

If you don't know how to flash back to stock manually you are probably better off using one of the toolkits in the development forums.

They seem to be stock kitkat. I would need to flash stock JB and then flash KK though, yeah?

No. Just wipe(cache, dalvik cache, data, and system) and then flash KK and you are done.
Another edit: Since you can't use a computer for this, you should download a few other ROMs so you have something else to flash if something goes wrong. I would really only recommend upgrading if you have access to a computer. Things can go wrong very easily. Good luck.
Thanks very much!
They aren't update custom ROMs, they're like factory images. You just need a kitkat 4.4 custom ROM that you can flash in custom recovery. If you don't have custom recovery on your tablet, you need to use your PC to flash it, or just boot temporarily.
Afterwards, restore your tablet, clear cache and dalvik cache, install zip, choose your custom rom, and flash it.
If there is an update for a ROM (such like nightlies for CM) you wouldn't have to restore the tablet, just flash the updated custom ROM because it's just an upgrade.

I attempted to flash a 4.4.2 rom yesterday but it couldnt and it gave me a status 7 error. I looked it up and people said that you have to update clockworkmod. Well i tried to through terminal but it couldn't. It said something like could not find directory. So if anyone has any idea what I can do pleast tell me.

If you can't flash a KK ROM, you may need to update your bootloader. If you're not on a 4.3 bootloader, try and avoid it for now.

im on a 4.3 rom but if i get error status 7 again ill just restore my backup and avoid it...is there a 4.3 bootloader? Also i was about to wipe it but its asking me wipe data/factory reset or clean to install a new ROM. I suggest its the 2nd one but if i do it and it doesnt work can i still restore my backup?

There is a 4.3 bootloader that would be installed if you ran an OTA update to 4.3 or you manually installed the 4.3 bootloader.
Did you make your backup using Philz? If not, make the backup using Philz, then wipe and install.

Doesn't really matter but it's good to know that you need to stay away from any attempts to downgrade the bootloader.

You can't restore to a completely stock ROM not that you have a 4.3 bootloader. AT&T never released a full 4.3 stock ROM, only an update to 4.3 from an earlier stock ROM.
If you did not have a 4.3 bootloader, you could install any stock AT&T ROM such as 4.1.1. Being able to restore to stock 4.1.1 would also allow you to sim unlock your phone for free, if necessary.

well im on rogers and its the same as att. i still have the original samsung touchwiz 4.1 rom just incase anything happens.
Your original post said you have an sgh-i747 which is an AT&T model. If you have a Rogers s3, it's an sgh-i747m.
Regardless of which model you have, you can't downgrade from any 4.3 bootloader which means you can't completely revert back to 4.1.1. The best you could do would be to run 4.1.1 on a 4.3 bootloader.

sorry i should have included the m lol. i wont worry about going back to 4.1 until the galaxy s5 comes out and im ready to give it to my dad. but back to focusing on this. im about to attempt to flash a 4.4.2 rom. either liquidsmooth or carbon. what do you like?
I prefer Validus version 4.3 because it includes Nova Launcher and it has a dark UI theme.
but thats 4.3. i wanna be on 4.4 and im installing nova and making it the way i had it before.
wait a second is it a 4.4 rom?

It is a 4.4.2-based rom. The release is version 4.3.
hmm interesting...you do recommend it? what great features does it come with?
I like it because it's a very stripped-down ROM, has a dark UI, and is AOSP-based.
It's not radically different from other ROMs but has exactly what I want. I run the same ROM on a Nexus 4 and Motorola Atrix HD.
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...

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?

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.
