[Q] unrooted back up can restore root? - G3 Q&A, Help & Troubleshooting

Hello,
I just exchanged my LG G3 D855. It was an unrooted phone updated to Lollipop OAE. I had a backup file created through the LG's own software. Now I have the same LG G3 but I rooted it with D85520A-boot-rooted-bumped-skin1980. If I use the restore from backup will by any chance restore the unrooted version of lollipop from my old phone?
Many thanks,

[Q] Re-root android 4.4.2 g3 on sprint

So my device was previously rooted on 4.4.2 and at the beginning of December there was an update available. I got excited thinking it was 5.0 so I decided to update. Well all it was was a patch I'm still on 4.4.2 unrooted now and I CAN'T get rerooted.. I've tried purpledrake I've tried stump (original root method) and I've tried ioroot.. None of which have worked.. Any suggestions out there?

1) Wrong section. There is a special forum for sprint's g3, go post in there.
2) Basically, you have to downgrage to rootable firmware, root it, install twrp, install newer (and already rooted) rom via it.
Okay thank you sorry.

[Q] Prepare for transition: 10L -> 20E & back.

Hi,
I have 855 (generic European version), V10L, rooted (using towel rooter), no TWRP, all OTA (since July 2014) installed automatically and seamlessly so far (keeping the root).
Today I got a prompt about V20E available upgrade.
I have LG PC Suite up-to-date backups of this device, and anyhow don't have anything that can't be restored, but in general prefer to not reconfigure everything manually.
Did nothing so far.
Questions:
Is it worth to move to V20E, is the version stable enough, worth to wait for V20F or whatever comes next ?
If I decide to proceed now, I want to be able to return to my current state (I do not need to fast switch between multiple roms, just way to get back V10L with my current configuration).
I prefer the way that allows me to keep receiving OTAs, and not to flush next updates manually.
After looking on the forums I though about the following workflows
First (without TWRP):
1. Create one more backup using LG PC Suite.
2. Unroot (just to be safe).
3. Accept OTA.
If I understand correctly I will loose root here, and it can not be restored (for now).
In case of need to restore:
1. Follow LG G3 Stock Firmware (Go Back to Stock) to flash D855 V10A. I hope after flushing it will receive 10L OTA ? Am I right, or I will be stuck with 10A ?
2. Restore my existing backup using LG PC Suite. If I do restore on V10A, will it bring me back to 10L ?
3. Reroot if needed.
Second, with TWRP:
1. Install TWRP.
2. Create full backup from inside TWRP.
3. Get prebumped Lollypop image (I see only V20C here. Where can I get more recent versions ?)
4. Install it and reroot if needed.
In this case I must reject upcoming OTA prompts and flash future prebumped images manually.
To restore
1. Restore full TWRP backup, and I'll get V10L with all my stuff preconfigured.
2. If at this step I want to get rid off TWRP, can I remove it somehow ? Will it restore the phone to the current state (rooted, V10L, able to get OTAs) ?
Sorry for multiple questions but currently the whole process looks a bit unclear for me.
Q: Is it worth to move to V20E, is the version stable enough, worth to wait for V20F or whatever comes next ?
A: No V20H got released today and its probably gonna be available in your region really soon
Note: If you do ever want to install stock lollipop please be aware LG backup cannot save the appdata of any system applications such as chrome etc etc
Q: Follow LG G3 Stock Firmware (Go Back to Stock) to flash D855 V10A. I hope after flushing it will receive 10L OTA ? Am I right, or I will be stuck with 10A ?
A: Check (http://lg-phone-firmware.com/index.php?id_mod=41) and download the v10 firmware the corrosponds with your country. If the firmware has a 6 in front of it its for the 16GB variant
Q: Where can I get more recent versions?
A: http://forum.xda-developers.com/lg-g3/development/stock-t2961073
Q: If at this step I want to get rid off TWRP, can I remove it somehow ? Will it restore the phone to the current state (rooted, V10L, able to get OTAs) ?
A: Yes, by flashing stock recovery.img. Restoring your TWRP backup will restore the phone to the current state

Thanks, but I am not sure about this one. What is the process ?
If I flash stock kdz it will remove TWRP, but I will not be able to restore TWRP backup (without TWRP), right ?
Is it possible to first restore TWRP backup, then flash "something" that will replace only TWRP, leaving android OS intact ?
Before saying anything, I would just like to give you a thank you for your post, it's very clear and pleasant to read. Looks like you also did a bit of research before asking so that is also very good :good:
So, I'm not gonna be able to help you a lot about the backup thing because I like to always start fresh when I change Rom or if I want to go back to stock. I backup my data manually and restore what I want to. Using a Google account it will automatically reinstall your apps, but you'll have to reconfigure them manually.
Anyway, I also got a D855, French variant A6FR. (A6 means 16GB) You can check what is the latest version that LG offers you by checking the link bellow. You just put your IMEI at the end and it will give you an XML with information about your phone, like your specific variant (German, UK, ... don't know where you are from) and the latest firmware available for your and a link to download it. For me it says D85520F_00 so it's LL version F.
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI
So, you can go back to stock using the KDZ method and with the firmware LG offers you (removing root, revovery, ...), but as you probably now, LL is not rootable. To summarize, that is not really interesting unless you want a STOCK STOCK LL.
But you guessed right with the V10A. If you go back to stock with this version, it will remove the root, custom recovery and anything else you have, you will also end up with a completely stock G3, but KitKat G3. There is no obligation to use V10A, if you find a KDZ of a later version you can use it too. Of course we are talking here about V10something not V20 that is LL. Just make sure to use a version suitable to your phone (16/32GB).
Flashing that, LG will be happy and will let you do OTAs. So if you flash V10A, it will give you all the OTAs untill the latest available. So you can go V10A --> V10B --> V10C --> ...... --> V10L --> ..... --> Lollipop
You won't be stuck with V10A.
Now if you want a rooted LL, you will need to use a custom Rom. In the Dev section you can find for example GloudyG3 that is based on the stock LG rom with a few enhancements. It is currently based on V20F and will probably move to V20H which is a brand new version that went up like 2 days ago.
To summarize
KDZ with V10something allows you to go completely stock and give you official OTAs. It can be rooted.
KDZ with V20something works too and will give you OTAs, but is not rootable, so if you want a custom rom, you will have to downgrade to V10, root and install TWRP.
Flashing a KDZ always erase everything on your phone.
If you flash a custom rom, you won't have LG's OTAs so you won't have to worry about rejecting them.
Before doing anything crazy, backup your EFS (basically your IMEI partion) with TWRP and manually. Always nice to have several ways to do it.

[Q] Downgrade from 23C to 10C?

I have a newly purchased verizon LG G3 that updated to 23C on its own. I have already rooted the device following a howto on lgg3 subreddit but in order to install Cyanogenmod the Cyanogenmod wiki says the phone needs to be 12B or lower. I found this http://forum.xda-developers.com/showthread.php?t=2799647 which says I can restore the phone back to 10C (it doesnt say 10C in the gudie but the user who posted on reddit said it) but I need the LG G3 files and I do not know where to get them. Any advice/recommendations how to get this? Is it possible I can perform a full backup incase something goes wrong I can restore the phone (its rooted already)?
