Hi,
So I bought an LG G3 a few weeks ago, rooted it and first flashed TWRP 2.8 to back up the stock ROM then flashed Cloudy G3 V1.2 this is the ROM I'm using now. I really wanna try Lollipop and already downloaded AndroidNow HD 7.0. Now my question is how should I flash this to make sure that it **** happens I'll be able to go back to my stock backup. As far as I know my version of TWRP does not back up the modem partition and since lollipop updates it as well.
What I was thinking is going back to stock rom from the back up, updating TWRP to the one that is able to backup the modem partition and then create a new backup and then flash AndroidNow HD 7.0. Is that necessary? Or am I good with the old backup?

Hello guys, i was wondering since I've made the 5.0 update (european) if it was possible for me to flash a custom rom like cyanogen without root (because root isn't an option since llp) ?

After flashing a ROM, flash SuperSu 2.4 to get root.
Sent from my Nexus 7 using XDA Free mobile app
But how do I flash without root ?
It's noobish question, i can't get to recovery, I've tried with the Power and vol down keys, all i can get is a menu to erase my data, thats it.
Firsh backup your data. Then go back to EU stock ROM:

Now you can root your LG G3, use TWRP/CWM custom recovery and flash custom ROM.

Thank you, I hoped there was another way, i will downgrade then, thanks.
maybe there is. Im not pro neither I received OTA for 5.0, but I wanted to have my LG rooted, so I had to downgrade and now I am running AN HD.
And use that to restore what is currently an F240 to Stock ATT? Clearly I have to root the stock one and install twrp, then back up the rom. If I get TWRP on the other device can I restore the stock rooted rom onto the F240? Has anyone done this?

yes. I'm pretty sure.
Hello guys,
following situation:
Long time I had a 4.4.something Rom installed. Before I flashed a custom Lollipop rom, I followed the advice to just go back to stock and let it update to Lollipop so that the firmware will be updated accordingly and I won't run into problems when flashing a Lollipop Custom Rom. Everything worked fine. Now I had to send my phone to HTC for display repair and just to make sure they won't nag about the custom Rom I reflashed some older stock rom via TWRP backup I found here, I think it was a 4.0 or so. The question is, does this also affect my phones firmware or is it still on the current newest level? So when I get it back, would I need to update to stock Lollipop again before flashing a custom rom or can I go for it straight away?

It won't affect your firmware.
Okay thanks, so Firmware should still be up to date and I can flash a Lollipop Custom Rom. I don't know what they do at HTC repair, if they only reset it or if they also update it, well I'll see.
I have been running marshmallow based custom roms and have made their nandroid backups in twrp. But after one bad incident(unresponsive screen) i gave it to service centre and landed up with stock kitkat..now i have a rooted stock kitkat with twrp recovery.. my question is ..can i just restore the marshmallow backup with twrp OR do i have to upgrade to stock marshmallow first.?
edit: nevermind..restored backup directly..

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.
